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).
Connective tissue cells which secrete an extracellular matrix rich in collagen and other macromolecules.
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.

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. We asked respondents to use the same scale used to develop the AUC; they rated 5 clinical scenarios from 1 (bad ...

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.
Acute coronary syndrome (ACS) is a common, sometimes difficult to diagnose spectrum of diseases occurring after abrupt reduction in blood flow through a coronary artery. Given the diagnostic challenge, it is sensible for emergency physicians to have an approach to prognosticate patients with possible ACS. Multiple prediction models have been developed to help identify patients at increased risk of adverse outcomes. The HEART score is the first model to be derived, validated, and undergo clinical impact studies in emergency department (ED) patients with possible ACS. To develop a protocol for a prognostic systematic review of the literature evaluating the HEART score as a predictor of major adverse cardiac events (MACE) in patients presenting to the ED with possible ACS. This protocol is reported according to the PRISMA-P statement and is registered on PROSPERO. All methodological tools to be used are endorsed by the Cochrane Prognosis Methods Group. Pre-defined eligibility criteria are provided.
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.. NASH supports the National Health Freedom Coalition and NASH is aligned with their goals and mission.. ...
Sep 26, 2016 , Orbital Disease, Patient Education, Thyroid (Graves) Eye Disease. Graves disease is an autoimmune condition in which immune cells attack the thyroid gland, which in turn responds by secreting an excess amount of thyroid hormone. As a result, the inflamed thyroid gland can enlarge (goiter) and excess hormone changes metabolism and affects the function of the heart, brain and other organs. The eyes are particularly vulnerable to thyroid disease, because the immune system that attacks the thyroid gland often also targets the eye muscles and connective tissue within the eye socket. The skin is also affected, but to a lesser degree in most patients. ...

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 ...

Is this stent necessary? Is this angioplasty inappropriate? Is this cardiologist uncertain if the procedure will help? Ever since the Appropriate Use Criteria for Coronary Revascularization were published, the three category labels of appropriate, uncertain, and inappropriate have confused the profession, press and population at large. The issue of definitions had still not been addressed in the most recent update of the AUC.. So (drumroll, please) yesterday, new categories were approved by the ACC Appropriateness Use Criteria Working Group. The new terminology will be Appropriate, May Be Appropriate(which replaces Uncertain), and Rarely Appropriate (which replaces Inappropriate).. I have written about this a number of times, most recently last December in my post, A Stent By Any Other Name, in which I called for a change:.

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. Fully 175 responses-among them a detailed letter by the American College of Cardiology (ACC)-made it into the Federal Register before the close of public comment on October 3.. The proposal was announced by the Department of Health & Human Services in July and, as reported by TCTMD, only eight individuals had commented by late September.. In addition to the ACC, the full list of respondents includes other cardiology-related professional groups such as the Society of Thoracic Surgeons, Heart Rhythm Society, American Heart Association, and Society for Cardiovascular Angiography and Interventions. Closely related subspecialties such as the American Geriatrics Society, American Telemedicine Association, and American Association of Nurse Practitioners also weighed in. Other ...

During 14 months, patients presenting with chest pain to the Emergency Department (ED) of participating hospitals will be included in the study. First, all hospitals will apply usual care to all patients, i.e. risk assessment and subsequent management without application of the HEART score. Then, during a 14 month period, each 1,5 month 1 randomly allocated hospital will sequentially start to apply the HEART score in all chest pain patients (intervention period); during this intervention period patients with a HEART score 0-3 will not be admitted to the hospital (in accordance with the results of our validation studies), and patients with a HEART score above 3 will be treated according to current guidelines ...

In this trial, criteria defining SAHF were inclusive of nearly every heart failure risk factor. Whereas this heterogeneity may have confounded results, as patients with different risk factors may progress to SBHF at different rates, a positive outcome would have been remarkably generalizable. It would also support revision of the appropriate use criteria for echocardiography, which currently do not consider screening to be indicated in most circumstances (4). There may also have been positive implications for health care costs, though it is unclear whether the added costs of screening and treatment would offset cost savings from delayed disease progression.. In excluding patients with pre-existing SBHF, Yang et al. (3) assigned a conservative cutoff of LVEF (,40%) as abnormal. Patients with mid-range EF (40% to 53%) without diastolic dysfunction or abnormal GLS were not considered to have SBHF. Whereas this may be controversial, it is not unreasonable; treatment of mid-rage EF has not shown ...
Greetings from Dallas, Texas, where the springtimes warmth and emerging colors are upon us. This has been a wonderful year to be a part of the SRS team, as the Societys productivity has never been greater.. Much has happened since our last newsletter in December. We held a productive Board of Directors (BOD) meeting during the February 2012 American Academy of Orthopaedic Surgeons (AAOS) Annual Meeting in San Francisco, California, USA. From the committee reports delivered, our 33 committees and ten taskforces are hard at work completing their numerous charges. These are year-long tasks and were fortunate to have strong leaders in the committee chair positions. The next day, we held a half-day seminar on the development of Appropriate Use Criteria (AUC) and Medical Decision Modeling. Teryl Nuckols, MD, an expert with the RAND Corporation, joined us as we further explored this concept for our Society. Earlier in October 2011 at the Cabinet Meeting, wed held an introductory half-day primer ...

The clinical utility of PET and PET/CT scanning as surveillance in asymptomatic patients or patients with chronic stable symptoms to detect disease recurrence is not well studied. Routine surveillance with PET and PET/CT scans in asymptomatic patients has not been shown to improve survival, provide better quality of life or impact the ability to palliate recurrent disease (make cancer or its symptoms less severe or unpleasant) and is therefore not recommended. The National Comprehensive Cancer Network (NCCN) clinical practice guidelines (Treatment of Cancer by Site) and NCCN Imaging Appropriate Use Criteria for various malignancies often note that PET and PET/CT scans are not recommended in asymptomatic individuals. Also, ASCO Choosing Wisely statement issued for providers includes until high level evidence demonstrates that routine surveillance with PET or PET/CT scans helps prolong life or promote well-being after treatment for a specific type of cancer, this practice should not be done.

The North American Society for Comparative Endocrinology (NASCE; Societé Nord-Americaine dEndocrinologie Comparée (SNAEC); Sociedad Norteamericana de Endocrinologìa Comparada (SNAEC)) is an interdisciplinary scientific organization dedicated to the study of comparative, evolutionary, ecological and model systems endocrinology. Endocrinology is the study of hormones and their actions. This field is rooted in the comparative study of hormones in diverse species, which has provided the foundation for the modern fields of evolutionary, environmental and biomedical endocrinology. The NASCE is distinguished from other professional societies in North America in that it serves scientists who, in addition to conducting research on biomedically important species like rodents and nonhuman primates, as part of their profession study diverse species including non-mammalian animal model systems.. The biennial meetings of the NASCE and its journal, General and Comparative Endocrinology provide essential ...

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. After all, we were starting a new professional organization without the sanction, of senior physicians in our field, and we were apprehensive about the way it ...

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 ...
The expected benefits of stenting in stable coronary artery disease (a reduction in the risk of death or heart attack), is not supported by its widespread usage and non-medical factors sometimes play a major influence on physician decision making.. On August 15, 2013 the NYTimes published an article in tune with a number of articles we have previously published on this website, most recently in a report on the recent stent implantation in President Bush:. Far too often, studies show, stents continue to be implanted in patients who stand to gain little if any benefit. Elective procedures performed on patients with stable coronary artery disease, a type that can cause chest pain and other symptoms during physical exertion but generally not at other times. Studies show that in these particular patients, inserting a stent is generally no better at preventing a heart attack or an early death than taking medication alone.. And yet many patients continue to undergo such procedures, even when there is ...
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. ...
