To produce knockouts, using RECOMBINANT DNA technology, the normal DNA sequence of the gene being studied is altered to prevent synthesis of a normal gene product. Cloned cells in which this DNA alteration is successful are then injected into mouse EMBRYOS to produce chimeric mice. The chimeric mice are then bred to yield a strain in which all the cells of the mouse contain the disrupted gene. Knockout mice are used as EXPERIMENTAL ANIMAL MODELS for diseases (DISEASE MODELS, ANIMAL) and to clarify the functions of the genes.Ventricular Pressure: The pressure within a CARDIAC VENTRICLE. Ventricular pressure waveforms can be measured in the beating heart by catheterization or estimated using imaging techniques (e.g., DOPPLER ECHOCARDIOGRAPHY).

In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.Thermodilution: Measurement of blood flow based on induction at one point of the circulation of a known change in the intravascular heat content of flowing blood and detection of the resultant change in temperature at a point downstream.Diastole: Post-systolic relaxation of the HEART, especially the HEART VENTRICLES.Echocardiography, Doppler: Measurement of intracardiac blood flow using an M-mode and/or two-dimensional (2-D) echocardiogram while simultaneously recording the spectrum of the audible Doppler signal (e.g., velocity, direction, amplitude, intensity, timing) reflected from the moving column of red blood cells.GATA4 Transcription Factor: A GATA transcription factor that is expressed in the MYOCARDIUM of developing heart and has been implicated in the differentiation of CARDIAC MYOCYTES.

The alpha-1 subunit is the binding site for calcium-based antagonists. Dihydropyridine-based calcium antagonists are used as markers for these binding sites.Tachycardia, Ventricular: An abnormally rapid ventricular rhythm usually in excess of 150 beats per minute. It is generated within the ventricle below the BUNDLE OF HIS, either as autonomic impulse formation or reentrant impulse conduction. Depending on the etiology, onset of ventricular tachycardia can be paroxysmal (sudden) or nonparoxysmal, its wide QRS complexes can be uniform or polymorphic, and the ventricular beating may be independent of the atrial beating (AV dissociation).Purkinje Fibers: Modified cardiac muscle fibers composing the terminal portion of the heart conduction system.3-Iodobenzylguanidine: A guanidine analog with specific affinity for tissues of the sympathetic nervous system and related tumors.

A variety of specific sodium channel subtypes are involved in serving specialized functions such as neuronal signaling, CARDIAC MUSCLE contraction, and KIDNEY function.Cardiovascular System: The HEART and the BLOOD VESSELS by which BLOOD is pumped and circulated through the body.Electric Countershock: An electrical current applied to the HEART to terminate a disturbance of its rhythm, ARRHYTHMIAS, CARDIAC. (Stedman, 25th ed)Gene Expression Regulation: Any of the processes by which nuclear, cytoplasmic, or intercellular factors influence the differential control (induction or repression) of gene action at the level of transcription or translation.Myosins: A diverse superfamily of proteins that function as translocating proteins. They share the common characteristics of being able to bind ACTINS and hydrolyze MgATP. Myosins generally consist of heavy chains which are involved in locomotion, and light chains which are involved in regulation. Within the structure of myosin heavy chain are three domains: the head, the neck and the tail. The head region of the heavy chain contains the actin binding domain and MgATPase domain which provides energy for locomotion. The neck region is involved in binding the light-chains. The tail region provides the anchoring point that maintains the position of the heavy chain. The superfamily of myosins is organized into structural classes based upon the type and arrangement of the subunits they contain.Heart Block: Impaired conduction of cardiac impulse that can occur anywhere along the conduction pathway, such as between the SINOATRIAL NODE and the right atrium (SA block) or between atria and ventricles (AV block). Heart blocks can be classified by the duration, frequency, or completeness of conduction block. Reversibility depends on the degree of structural or functional defects.Norepinephrine: Precursor of epinephrine that is secreted by the adrenal medulla and is a widespread central and autonomic neurotransmitter. Norepinephrine is the principal transmitter of most postganglionic sympathetic fibers and of the diffuse projection system in the brain arising from the locus ceruleus. It is also found in plants and is used pharmacologically as a sympathomimetic.Sodium-Calcium Exchanger: An electrogenic ion exchange protein that maintains a steady level of calcium by removing an amount of calcium equal to that which enters the cells. It is widely distributed in most excitable membranes, including the brain and heart.Defibrillators: Cardiac electrical stimulators that apply brief high-voltage electroshocks to the HEART. These stimulators are used to restore normal rhythm and contractile function in hearts of patients who are experiencing VENTRICULAR FIBRILLATION or ventricular tachycardia (TACHYCARDIA, VENTRICULAR) that is not accompanied by a palpable PULSE. Some defibrillators may also be used to correct certain noncritical dysrhythmias (called synchronized defibrillation or CARDIOVERSION), using relatively low-level discharges synchronized to the patient's ECG waveform. (UMDNS, 2003)Hypothermia, Induced: Abnormally low BODY TEMPERATURE that is intentionally induced in warm-blooded animals by artificial means. In humans, mild or moderate hypothermia has been used to reduce tissue damages, particularly after cardiac or spinal cord injuries and during subsequent surgeries.Analysis of Variance: A statistical technique that isolates and assesses the contributions of categorical independent variables to variation in the mean of a continuous dependent variable.Magnetic Resonance Imaging: Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.Cardiology: The study of the heart, its physiology, and its functions.Emergency Medical Services: Services specifically designed, staffed, and equipped for the emergency care of patients.Sensitivity and Specificity: Binary classification measures to assess test results. Sensitivity or recall rate is the proportion of true positives. Specificity is the probability of correctly determining the absence of a condition. (From Last, Dictionary of Epidemiology, 2d ed)Electrophysiology: The study of the generation and behavior of electrical charges in living organisms particularly the nervous system and the effects of electricity on living organisms.Calcium Signaling: Signal transduction mechanisms whereby calcium mobilization (from outside the cell or from intracellular storage pools) to the cytoplasm is triggered by external stimuli. Calcium signals are often seen to propagate as waves, oscillations, spikes, sparks, or puffs. The calcium acts as an intracellular messenger by activating calcium-responsive proteins.Models, Animal: Non-human animals, selected because of specific characteristics, for use in experimental research, teaching, or testing.Heart Massage: Rhythmic compression of the heart by pressure applied manually over the sternum (closed heart massage) or directly to the heart through an opening in the chest wall (open heart massage). It is done to reinstate and maintain circulation. (Dorland, 28th ed)Cardiac-Gated Imaging Techniques: Timing the acquisition of imaging data to specific points in the cardiac cycle to minimize image blurring and other motion artifacts.Electrocardiography, Ambulatory: Method in which prolonged electrocardiographic recordings are made on a portable tape recorder (Holter-type system) or solid-state device ("real-time" system), while the patient undergoes normal daily activities. It is useful in the diagnosis and management of intermittent cardiac arrhythmias and transient myocardial ischemia.Calcium-Binding Proteins: Proteins to which calcium ions are bound. They can act as transport proteins, regulator proteins, or activator proteins. They typically contain EF HAND MOTIFS.Gene Expression: The phenotypic manifestation of a gene or genes by the processes of GENETIC TRANSCRIPTION and GENETIC TRANSLATION.Rhabdomyoma: A benign tumor derived from striated muscle. It is extremely rare, generally occurring in the tongue, neck muscles, larynx, uvula, nasal cavity, axilla, vulva, and heart. These tumors are treated by simple excision. (Dorland, 27th ed; DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p1354)Perfusion: Treatment process involving the injection of fluid into an organ or tissue.Cardiography, Impedance: A type of impedance plethysmography in which bioelectrical impedance is measured between electrodes positioned around the neck and around the lower thorax. It is used principally to calculate stroke volume and cardiac volume, but it is also related to myocardial contractility, thoracic fluid content, and circulation to the extremities.Death, Sudden: The abrupt cessation of all vital bodily functions, manifested by the permanent loss of total cerebral, respiratory, and cardiovascular functions.Cardiovascular Agents: Agents that affect the rate or intensity of cardiac contraction, blood vessel diameter, or blood volume.Phosphorylation: The introduction of a phosphoryl group into a compound through the formation of an ester bond between the compound and a phosphorus moiety.Phenotype: The outward appearance of the individual. It is the product of interactions between genes, and between the GENOTYPE and the environment.Blood Circulation: The movement of the BLOOD as it is pumped through the CARDIOVASCULAR SYSTEM.Swine: Any of various animals that constitute the family Suidae and comprise stout-bodied, short-legged omnivorous mammals with thick skin, usually covered with coarse bristles, a rather long mobile snout, and small tail. Included are the genera Babyrousa, Phacochoerus (wart hogs), and Sus, the latter containing the domestic pig (see SUS SCROFA).Muscle, Skeletal: A subtype of striated muscle, attached by TENDONS to the SKELETON. Skeletal muscles are innervated and their movement can be consciously controlled. They are also called voluntary muscles.Survival Rate: The proportion of survivors in a group, e.g., of patients, studied and followed over a period, or the proportion of persons in a specified group alive at the beginning of a time interval who survive to the end of the interval. It is often studied using life table methods.Monitoring, Physiologic: The continuous measurement of physiological processes, blood pressure, heart rate, renal output, reflexes, respiration, etc., in a patient or experimental animal; includes pharmacologic monitoring, the measurement of administered drugs or their metabolites in the blood, tissues, or urine.Dobutamine: A catecholamine derivative with specificity for BETA-1 ADRENERGIC RECEPTORS. It is commonly used as a cardiotonic agent after CARDIAC SURGERY and during DOBUTAMINE STRESS ECHOCARDIOGRAPHY.Postoperative Period: The period following a surgical operation.Membrane Potentials: The voltage differences across a membrane. For cellular membranes they are computed by subtracting the voltage measured outside the membrane from the voltage measured inside the membrane. They result from differences of inside versus outside concentration of potassium, sodium, chloride, and other ions across cells' or ORGANELLES membranes. For excitable cells, the resting membrane potentials range between -30 and -100 millivolts. Physical, chemical, or electrical stimuli can make a membrane potential more negative (hyperpolarization), or less negative (depolarization).Fibroblasts: Connective tissue cells which secrete an extracellular matrix rich in collagen and other macromolecules.Atrial Fibrillation: Abnormal cardiac rhythm that is characterized by rapid, uncoordinated firing of electrical impulses in the upper chambers of the heart (HEART ATRIA). In such case, blood cannot be effectively pumped into the lower chambers of the heart (HEART VENTRICLES). It is caused by abnormal impulse generation.Diabetic Cardiomyopathies: Diabetes complications in which VENTRICULAR REMODELING in the absence of CORONARY ATHEROSCLEROSIS and hypertension results in cardiac dysfunctions, typically LEFT VENTRICULAR DYSFUNCTION. The changes also result in myocardial hypertrophy, myocardial necrosis and fibrosis, and collagen deposition due to impaired glucose tolerance.Cardiac Output, High: A state of elevated cardiac output due to conditions of either increased hemodynamic demand or reduced cardiac oxygen output. These conditions may include ANEMIA; ARTERIOVENOUS FISTULA; THYROTOXICOSIS; PREGNANCY; EXERCISE; FEVER; and ANOXIA. In time, compensatory changes of the heart can lead to pathological form of high cardiac output and eventual HEART FAILURE.Tachycardia: Abnormally rapid heartbeat, usually with a HEART RATE above 100 beats per minute for adults. Tachycardia accompanied by disturbance in the cardiac depolarization (cardiac arrhythmia) is called tachyarrhythmia.Potassium Channels: Cell membrane glycoproteins that are selectively permeable to potassium ions. At least eight major groups of K channels exist and they are made up of dozens of different subunits.Blotting, Western: Identification of proteins or peptides that have been electrophoretically separated by blot transferring from the electrophoresis gel to strips of nitrocellulose paper, followed by labeling with antibody probes.Heart Arrest, Induced: A procedure to stop the contraction of MYOCARDIUM during HEART SURGERY. It is usually achieved with the use of chemicals (CARDIOPLEGIC SOLUTIONS) or cold temperature (such as chilled perfusate).Patch-Clamp Techniques: An electrophysiologic technique for studying cells, cell membranes, and occasionally isolated organelles. All patch-clamp methods rely on a very high-resistance seal between a micropipette and a membrane; the seal is usually attained by gentle suction. The four most common variants include on-cell patch, inside-out patch, outside-out patch, and whole-cell clamp. Patch-clamp methods are commonly used to voltage clamp, that is control the voltage across the membrane and measure current flow, but current-clamp methods, in which the current is controlled and the voltage is measured, are also used.

How is Control Area Criteria Task Force abbreviated? CACTF stands for Control Area Criteria Task Force. CACTF is defined as Control Area Criteria Task Force very rarely.
The indications included in this publication cover a variety of cardiovascular signs and symptoms as well as clinical judgments as to the likelihood of cardiovascular findings. Within each main disease category, a standardized approach was used to capture a significant number of clinical scenarios without making the list of indications excessive. The term "indication" is used interchangeably with "clinical scenario" in the document for brevity and does not imply that imaging should necessarily be done. Diagnostic catheterization may include several different procedure components. The indications developed focused primarily on 2 aspects of diagnostic catheterization. Many indications focused on the performance of coronary angiography for the detection of coronary artery disease (CAD), with other procedure components (e.g., hemodynamic measurements, ventriculography) performed at the discretion of the operator. The majority of the remaining indications focused on hemodynamic measurements to ...

Appropriate use criteria (AUC) have been developed for a variety of cardiovascular tests and services. AUC are based on the best available evidence with the goal of identifying which clinical scenarios are likely to result in net patient benefit or harm. Little is known about how well physicians on the clinical care frontlines know about and apply AUC when making decisions about care. Patients do not have a role in developing AUC; their reflections on appropriateness of care have not been well studied.. We conducted an anonymous survey of patients and health care providers and asked them to rate the appropriateness of myocardial perfusion imaging (MPI) for a series of clinical scenarios. We also gathered data on attitudes and awareness of issues related to AUC. We hypothesized that patients and providers would overestimate the appropriateness of MPI compared with the published AUC.

The American College of Cardiology, along with several partnering organizations, today released updated appropriate use criteria for performing coronary revascularization in patients with stable ischemic heart disease.
To apply more appropriate labels to utilization norms, new terminology has been approved for the ACCFs Appropriate Use Criteria (AUC). Starting with the set of AUC released last month covering the use of implantable defibrillators, future criteria will be categorized as appropriate, maybe appropriate, and rarely appropriate. This replaces the original AUC terms: appropriate, uncertain, and inappropriate. In an AUC Methodology Update, published online at JACC on February 22, the AUC Task Force notes that the categorical nature of the original AUC terminology "often led to misperceptions by all stakeholders about when a procedure may be considered for a patient.". Peter L. Duffy, MD, was one interventionalist who came to believe that use of the term "inappropriate" was itself inappropriate. "I think its really important that we get rid of that term," said the director of cardiovascular quality at Reid Heart Center, Pinehurst, North Carolina. "There are always cases where we all agree that while ...

WASHINGTON, D.C., and DALLAS (March 17, 2014) - The increasing number of percutaneous coronary interventions (PCIs) being performed at low-volume centers without on-site cardiac surgery backup has driven the need for new safety and quality protocols, according to an expert consensus document released today and written by a committee representing the Society for Cardiovascular Angiography and Interventions (SCAI), the American College of Cardiology Foundation (ACCF) and the American Heart Association (AHA). The document outlines steps hospitals can take to provide the safest possible environment for PCI when the facility does not provide cardiac surgery as a backup should complications occur.
How do we end the misconceptions? First, institutions like the AHA should be more proactive in educating doctors about the inflammatory disease model and how to communicate it to patients. The 2011 American College of Cardiology Foundation/AHA/Society for Cardiovascular Angiography and Interventions guideline for PCI23 is a step in the right direction, stating that patients considering PCI "should understand when the procedure is being performed in an attempt to improve symptoms, survival, or both." The guideline points out that "evaluation of 61 trials of PCI conducted over several decades shows that despite improvements in PCI technology and pharmacotherapy, PCI has not been demonstrated to reduce the risk of death or [myocardial infarction] in patients without recent [acute coronary syndrome]" but makes no mention of pathophysiology. Few medical questions have engendered 61 randomized trials, yet the authors of the guideline still rate the Level of Evidence as "B" (limited populations ...
Each and every one of us has the right to make our own unique health care choices to keep ourselves healthy and happy. As Americans, we believe these freedoms are intrinsic to all. NASH believes that public policy and laws must allow for freedom of choice. An acceptable balance must be created between individual rights to self-determination, and the governments concerns for public safety.. Vaccination is a personal consideration and choice. There are numerous factors that must be considered in each individual case. NASH advocates each individual doing as much research as they need to feel satisfied with the choices they make for themselves and their family; furthermore all of the information about potential benefits or harm must be available to everyone to make appropriate choices..

The report was issued today by the Society for Cardiovascular Angiography and Interventions (SCAI) and is published online in Catheterization and Cardiovascular Interventions.. Up to half of all patients with coronary artery disease have blockages in more than more artery. As many as one in five percutaneous coronary intervention (PCI) patients receives treatment in more than one vessel. SCAIs new clinical document reviews treatment options for these patients and provides recommendations for treatment of multiple vessels in one stage or in multiple stages.. "When multiple arteries are treated it is usually done in one session, which may not be the safest approach," said James C. Blankenship, M.D., FSCAI, lead author of the new document. "Yet interventional cardiologists have not had comprehensive recommendations on when it is better to split the treatment of several arteries into two sessions. Splitting the procedure into separate sessions is less convenient for patients and more costly to ...

Background: There has been a significant increase in myocardial perfusion imaging (MPI) exams performed. Appropriate use criteria (AUC) have been published to provide guidance in the use of MPI testing. However, limited data are available regarding the evaluation of AUC and how it relates to repeat MPI testing and MPI Results.. Hypothesis: We hypothesized that most repeat MPI exams would be performed for appopriate indications and sought to determine the timing between repeat MPI exams and their relation to AUC.. Methods: The electronic medical record was reviewed, including the MPI report with a listed indication as well as clinical notes and diagnostic codes. A single best indication for each test was identified, a MPI appropriate use classification was assigned based on current multisociety guidelines, and MPI results were recorded.. Results: Of 1097 patients undergoing index MPI, 424 underwent additional MPI. Median time between repeated MPI exams was 23.7 months. 56% of patients undergoing ...
More than 1 million stents are implanted annually in the United States to treat coronary disease, in the continuing hope that they are more effective than medical therapy in preventing heart attacks and prolonging life, despite abundant evidence to the contrary. Despite the highly publicized COURAGE findings, fewer than half of Americans with stable CAD who undergo stent placement have received medical therapy first. This latest meta-analysis, looking at recent PCI trials, again finds no benefit of PCI compared with medical therapy. Increasing use of American College of Cardiology Appropriate Use Criteria and realigning incentives for evidence-based approach will help improve quality of care. A "PCI first" strategy for patients with stable CAD gets a Less Is More designation because there is no known benefit and there are definite harms.". Rita F. Redberg, MD, MSc, ...

Coronary artery disease (CAD) is a major cause of death and disability. Several diagnostic tests, such as myocardial perfusion scintigraphy (MPS), are accurate for the detection of CAD, as well as having prognostic value for the prediction of cardiovascular events. Nevertheless, the diagnostic and prognostic value of these tests should be cost-effective and should lead to improved clinical outcome. We have reviewed the literature on the cost-effectiveness of MPS in different circumstances: (i) the diagnosis and management of CAD; (ii) comparison with exercise electrocardiography (ECG) and other imaging tests; (iii) as gatekeeper to invasive coronary angiography (ICA), (iv) the impact of appropriate use criteria; (v) acute chest pain, and (vi) screening of asymptomatic patients with type-2 diabetes ...

OBJECTIVE: The HEART score can accurately stratify the risk of major adverse cardiac events (MACE) in patients with chest pain. We investigated the frequency, circumstances and potential consequences of errors in its calculation. METHODS: We performed a secondary analysis of a stepped wedge trial of patients with chest pain presenting ... read more to nine Dutch emergency departments. We recalculated HEART scores for all patients by re-evaluating the elements age (A), risk factors (R) and troponin (T) and compared these new scores with those given by physicians in daily practice. We investigated which circumstances increased the probability of incorrect scoring and explored the potential consequences. RESULTS: The HEART score was incorrectly scored in 266 out of 1752 patients (15.2%; 95% CI 13.5% to 16.9%). Most errors occurred in the R (Risk factors) element (61%). Time of admission, and patients age or gender did not contribute to errors, but more errors were made in patients with higher ...
The clinical importance of autonomic control became apparent in the late 1980s, when heart rate variability (HRV) was confirmed to be strong and independent predictor of mortality after acute myocardial infarction. There was a significant relationship between the autonomic nervous system and cardiovascular mortality, including sudden cardiac death. Thanks to the availability of high frequency 24-h electrocardiographic Holter recorders, HRV can potentially provide additional valuable insight into physiological and pathological conditions and risk stratification in different cardiac diseases [53], [54], [55]. There are many commercial available automated HRV measurement devices utilizing variety of methods [56], [57], [58], providing cardiologists with a seemingly simple tool for both research and clinical studies. In 1996, a Task Force of the European Society of Cardiology and the North American Society of Pacing and Electrophysiology defined time and frequency domain parameters for the ...

The Australasian accelerated protocol studies [3-6] used hs-cTn, which is not approved for use in the United States. The HEART Score, however, provided a prospectively validated risk assessment tool [7, 8] that had been studied and validated in the United States [9,10]. This tool is safe, efficient, and uses the FDA-approved conventional cTN I.. The HEART score (details at heartscore.org) was developed using the conventional troponin assay, cTNI. It is an easily applied scoring system that can be built into an existing electronic health record template.. The external, prospective validation by Backus, et al. [4,8], demonstrated that of 2388 patients with chest pain, only 1.7% of patients with a score of 0-3 had a major adverse cardiac event within 6 weeks. This proportion was further reduced to ,1% when a second troponin was added at hour 3 in the studies of Mahler, et al [9,10].. Based on the above information, the University of Maryland Risk Forum formally recommended the use of the HEART ...

Abstract:. Fetal Alcohol Syndrome (FAS), is something whose mere mention implies different things to different people. It is a syndrome immersed in stereotypes by the North American society in which we live, the majority of which are sadly negative. In the paper that follows, though written from a North American perspective, I will refrain from examining the specifics of these stereotypes, for to acknowledge them would only give them attention that I do not believe that they deserve in the context of this article.. This paper is about FAS and the way we, as a North American society, educate people about its known, and possible, causes. The paper is split into six sections. It begins by looking at a history of the discovery of FAS and Fetal Alcohol Effects, (FAE) and goes on to define each to avoid confusion within the paper. Having dealt with descriptions of FAS/FAE, it briefly examines four articles that offer a contrasting view to that of the mother being soley responsible for a child with ...

The wide-spread use of drug-eluting stents (DES) has evolved as standard of care in de novo lesions. The PROMUS Element Plus Everolimus-Eluting Platinum Chromium Coronary Stent System is indicated for improving luminal diameter in patients with symptomatic heart disease or documented silent ischemia due to de novo lesions in native coronary arteries ≥2.25 mm to ≤4.00 mm in diameter in lesions ≤34 mm in length. The proposed study will compile real-world clinical outcomes data for the PROMUS Element Plus Everolimus-Eluting Platinum Chromium Coronary Stent System in routine clinical practice.. Patients enrolled in this study are expected to follow antiplatelet therapy recommendations per American College of Cardiology (ACC)/American Heart Association (AHA)/Society for Cardiovascular Angiography and Interventions (SCAI) guidelines for percutaneous coronary intervention (PCI). Recommended medications include aspirin, which should be taken for 3 days prior to the procedure or as a ...
At first, the US governments plan to bundle Medicare payments related to MI care and bypass surgery was met with what seemed like lukewarm curiosity. But now it seems the muted reaction could be blamed on procrastination.

Several months later, in early March of 1982, I attended a meeting of the Aspen Retinal Detachment Society with Dr. Levit and Dr. Verne. The three of us, along with our wives, had an intimate dinner at Poppys Restaurant in Aspen. I discussed Esters idea of forming a new subspecialty society. Everyone at the dinner table enthusiastically applauded the concept.. Fortunately, Roy Levit took prompt action. Immediately after he returned to El Paso, he asked an attorney to incorporate the Vitreous Society as a non-profit organization in his home state. Simultaneously, Allen Verne attacked the process of designing and printing membership certificates. The executive offices of the society were located in Toledo, Ohio, where I maintained my vitreoretinal practice.. With great trepidation, I configured a letter to the invited charter members.

An analysis of clinical practice guidelines archived on the National Guideline Clearinghouse (NGC) website as of June 2011 demonstrated poor compliance with Institute of Medicine (IOM) standards, with little if any improvement over the past 2 decades, say authors of an article published this month in Archives of Medicine. For the study, 2 reviewers independently screened 130 guidelines selected at random from NGCs website for compliance with 18 of 25 IOM standards.. The overall median number of IOM standards satisfied (out of 18) was 8 (44.4%). Fewer than half of the guidelines surveyed met more than 50% of IOM standards. Barely a third of the guidelines produced by subspecialty societies satisfied more than 50% of the IOM standards surveyed. Information on conflicts of interest was given in fewer than half of the guidelines surveyed. Non-English literature, unpublished data, and/or abstracts were rarely considered in developing guidelines. Differences of opinion among committee members ...

We agree with Weinfurt and colleagues that diagnostic technologies such as the ACI-TIPI should be evaluated in prospective controlled clinical trials. As emphasized by the National Institutes of Health National Heart Attack Alert Program (NHAAP) Diagnostic Technologies Working Group report (1), not only should such technologies be shown to have good diagnostic performance in relevant patients, but also they should be demonstrated to be safe and effective in actual use in clinical care. The latter is crucial, because even if a tests diagnostic performance is good in isolation, this may not translate into better physician decision making (2, 3) ...
This chapter about antithrombotic therapy for coronary artery disease (CAD) is part of the Seventh ACCP Conference on Antithrombotic and Thrombolytic Therapy: Evidence Based Guidelines. Grade 1 recommendations arestrong and indicate that the benefits do, or do not, outweigh risks, burden, and costs. Grade 2 suggests that individual patients values may lead to different choices (for a full understanding of the grading see Guyatt et al, CHEST 2004; 126:179S-187S). Among the key recommendations in this chapter are the following: For patients presenting with non-ST-segment elevation (NSTE) acute coronarysyndrome (ACS), we recommend immediate and then daily oral aspirin (Grade 1A). For patients with an aspirin allergy, we recommend immediate treatment with clopidogrel, 300-mg bolus po, followed by 75 mg/d indefinitely (Grade 1A). In all NSTE ACS patients in whom diagnostic catheterization will be delayed or when coronary bypass surgery will not occur until > 5 days, we recommend clopidogrel as ...
Some children arrive in Israel only to wait for weeks, sometimes months, before their surgery date. For others, like Yasna, there is barely enough time to become acquainted before the operation takes place. This adorable toddler made her grand entrance into Israel one week ago and received some surprising and very welcome news today. Originally, Yasna was scheduled to have a diagnostic catheterization of her heart this Wednesday, with surgery most likely the following week. In an unexpected turn of events, however, Yasna was invited to Wolfson today for a welcome surprise!. I was at the hospital with two other Kurdish families when Dr. Alona requested that we bring Yasna in as soon as possible. It was decided that she did not require a cath after all. Moreover, there happened to be an opening in the OR schedule for tomorrow morning! Several volunteers helped Yasna and her mother quickly prepare and leave for Tel Aviv. When they arrived, I was outside waiting, thankful to share in this good news. ...

Instructive case with important messages! As to the ECG - features supporting a non-acute picture are: i) How extreme the increase in voltage is (through the overlap in V4-V5, one can see that the R in V5 is no less than 31mm! - and the S in V2 no less than 25mm! - not too mention the S in V3 that goes off the page); ii) If one flips this ECG upside down (ie, applies the "mirror test") - the slightly elevated ST-T waves seen in V1,V2,V3 now take on an appearance identical to that expected for lateral lead LV "strain"; and iii) The "pseudo-Wellens" ST-T wave appearance that we see in lead V4 is exactly what one might expect if you "fused" the ST-T wave appearance in neighboring leads V3 and V5. I generally write down on my official interpretation, "LVH with strain and/or ischemia" for my assessment of ST-T wave appearance seen here in the 6 chest leads - but the important point, is to appreciate how this overall ST-T wave pattern is probably longterm, and clearly unlikely to account for this ...
