Comment from Dr. Jennifer Johnson (Pittsburgh, PA), Section Editor of Pediatric Cardiology Journal Watch: This is a single center retrospective chart review of all pediatric hypertrophic cardiomyopathy patients who underwent exercise stress echocardiography to determine if exercise stress echocardiography can be useful in risk stratifying hypertrophic cardiomyopathy subgroups and if LVOT obstruction occurs in the patients with nonobstructive hypertrophic cardiomyopathy.. Methods: Data was collected on all pediatric hypertrophic cardiomyopathy patient who underwent exercise stress echocardiography from 2007-2018 at Boston Childrens Hospital. Subjects were assigned to one of three categories based on left ventricular outflow tract gradients: group 1: ,30 mm Hg at rest and exercise; group 2: ,30 mm Hg at rest and ≥30 mm Hg with exercise; and group 3: ≥ 30 mm Hg at rest and exercise. The composite adverse endpoints on follow-up included heart transplant, aborted cardiac arrest, and sudden ...
Commentary from Dr. Jared Hershenson (Greater Washington DC), section editor of Pediatric Cardiology Journal Watch: Exercise stress echocardiography (ESE) is not a commonly used modality in pediatric patients and there are few published studies reporting the utility of ESE in this population. ESE is commonly used to assess cardiac function in adults with coronary issues, hypertrophic cardiomyopathy (HCM), aortic valve disorders, and EKG abnormalities (e.g. LBBB), but some pediatric labs have started to use ESE in pediatric patients with many of the above issues. The primary aim of this study was to evaluate the utility of ESE in a large single pediatric program and a secondary aim was to see how ESE impacted clinical management. Test indications were divided into 5 categories: 1) symptoms with exercise, 2) sports/activity clearance, 3) HCM, 4) coronary abnormalities, and 5) abnormal EKG. It was not clearly stated, but patients with pre-existing CHD (besides coronary anomalies) were seemingly ...
A stress echocardiogram (or stress echo) is a diagnostic test usually used to assess for coronary artery disease but can also be used in assessment of valvular heart disease. It is an ultrasound test performed both at rest and then with the heart under stress. The stress is achieved either by exercising on a treadmill or by receiving a medication which stimulates the heart - see dobutamine stress echocardiogram. Your doctor will decide which is the better option for you. The test takes around 1 hour.

Introduction: Stress echocardiography is a safe and cost-effective method of evaluating the patients with suspected coronary artery disease (CAD). However, the risk factors of an adverse cardiovascular event after a normal exercise (ESE) or dobutamine (DSE) stress echocardiography are not well established. Methods: A cohort of 705 patients without previous history of CAD and a negative ESE/DSE was studied. All studies were performed in a high-volume echocardiologic laboratory and interpreted by two experienced echocardiography-trained cardiologists. Patients with inconclusive studies and those with an evidence of myocardial ischemia were excluded. Demographic, echocardiographic and hemodynamic findings were recorded. Patients were followed for at least 2 years. Independent predictors of major adverse cardiovascular events (MACE) were determined by regression analysis. Results: During a period of 55.7±17.5 months, MACE occurred in 35 (5.0%) of patients. Negative predictive value (NPV) of DSE was 89.2%

Coronary heart disease (CHD) continues to be a major global cause of death and morbidity. Tremendous resources have been invested in diagnosing CHD and predicting CHD mortality and morbidity. Although Framingham and other risk scores have contributed importantly to risk stratification of patients with suspected CHD, they are imperfect. Consequently, major efforts have been devoted to investigating the incremental utility of cardiac noninvasive imaging techniques, serum biomarkers, and so on, in predicting mortality and morbidity in patients with suspected CHD.. In this issue of iJACC, Gaibazzi, et al. (1) present the results of a retrospective multicenter transthoracic echocardiography assessment of the value of an echocardiographic calcium score (eCS) in addition to stress-induced left ventricular (LV) wall motion abnormalities (WMAs) as detected by exercise or pharmacological stress echocardiography in predicting myocardial infarction (MI) and all-cause mortality.

AIMS: To determine if perfusion stress echocardiography (PSE) with Imagify (perflubutane polymer microspheres) is comparable to stress perfusion imaging using (99m)Tc single photon emission computed tomography (SPECT) for coronary artery disease (CAD) detection. PSE is a novel technique for evaluating myocardial perfusion. RAMP (real-time assessment of myocardial perfusion)-1 and -2 were international, Phase 3 trials that evaluated the ability of PSE with Imagify, to detect CAD. METHODS AND RESULTS: Chronic, stable, chest pain patients (n=662) underwent Imagify PSE and gated SPECT imaging at rest and during dipyridamole stress. Independent blinded cardiologists [three PSE readers per trial, and four SPECT readers (one for RAMP-1, three for RAMP-2)] interpreted images. CAD was defined by quantitative coronary angiography or 90-day outcome with clinical review. Accuracy, sensitivity, and specificity were evaluated using non-inferiority analysis (one-sided alpha=0.025) compared with SPECT. SPECT ...
A Stress Echocardiogram is a non-invasive test that combines two tests: a treadmill stress test and an echocardiogram (an ultrasound of the heart). If there are any abnormalities in heart function after exercise, this may be due to a blocked artery or coronary artery disease (CAD). This information is useful to your doctor to help establish a diagnosis and guide your treatment.. What to Expect During a Stress Echocardiogram. A stress echocardiogram is done by a cardiologist who is assisted by a specially certified technician called an echocardiographer. The echocardiographer will begin by placing electrodes on your chest to monitor your heart rate and rhythm throughout the test. First the echocardiogram will be performed at rest while you lie on the exam table.. Immediately following, you will begin to walk on the treadmill, which normally gets faster and steeper every three minutes. You will exercise until the doctor says you have done enough or you indicate that you have done enough. If you ...
Stress echocardiography, or stress echo, is a test that records images of your heart before and after exercise. By comparing the images, your doctor can tell whether your heart is getting enough blood to meet its increased demand for oxygen.
Stress echocardiography assesses the likelihood that you have significant narrowings in your heart arteries. By comparing your heart function before and after exercise using echocardiography
Exercise stress testing has been widely undertaken for the diagnosis of heart diseases. The accurate assessment of clinical conditions can be conducted by comparing the findings obtained from the results of stress echocardiography with the changes in the blood/heart rate and electrocardiograms. Numerous overseas studies have reported the utility of stress echocardiography in diagnosing myocardial ischemia; in Japan, the use of this modality for this purpose was included in the national health insurance reimbursable list in 2012. Nevertheless, stress echocardiography is far from being a widespread practice in Japan. This might be due to insufficient equipment (e.g., ergometers, space for test implementation) at each medical institution, shortage of technicians and sonographers who are well experienced and who are responsible for obtaining images during stress testing. The other possible reasons include the limited evidence available in Japan and the lack of a standardized testing protocol. ...

BACKGROUND: Interpretation of dobutamine stress echocardiogram (DSE) is often subjective and requires expert training. The purposes of this study was to determine optimal cutoff values for longitudinal, circumferential, and radial strains at peak DSE
Echocardiography is a test that uses ultrasound techniques to produce images of the heart in real time. Stress echocardiography uses this technique to evaluate the heart rate response while performing an activity in which the heart has to work (stress). Stress echocardiography can reveal traces of cardiovascular disease in its early stages, before it manifests, and so this technique becomes a valuable screening tool.. A protocol of stress echocardiography that has proved to have advantages in the clinical practice is obtained while performing handgrip exercises. However, the maximal exercise levels are not easily quantified and regulated, requiring the analysis of the complete data sequences (thousands of images), which poses a challenge for the clinician.. An analytical framework is proposed that explicitly addresses the practical challenges posed by analysing thousands of complete data and illustrates the potential of their study on a specific group of heart patients. A study published in the ...

Results Of 591 recruited patients, 580 (men, 46%; mean age 59 ± 11 years) patients were available for follow-up. SE demonstrated myocardial ischemia in 12%, but prevalence of carotid plaques was 59%. During a mean follow-up of 1,117 ± 361 days, 40 first MAEs occurred. In the multivariable regression model, pre-test probability (PTP) of CAD (p = 0.001), abnormal SE (p , 0.0001), and CPB (p , 0.0001) predicted MAEs. MAE rates per year increased from 0.9% versus 1.97% versus 4.3% versus 9.7% in patients with no carotid plaque and normal SE versus patients who had plaque and normal SE versus those with no plaque and abnormal SE versus patients with plaque and abnormal SE, respectively (p , 0.0001). In hierarchical analysis, plaque burden provided incremental prognostic value over PTP of CAD and SE; likewise, SE was incremental to PTP-CAD and CPB (p , 0.0001 for both). ...

Treadmill, stress echocardiography, Thallium and Angiography do not detect early blockages. Treadmill can miss blockages up to 70%; stress echocardiography up to 60%, angiography upto 40%.. Most heart attacks occur because of a plaque rupture in patients with blockages of less than 50%. If the blockage is more than 70% the patient usually presents with heart pain and not massive heart attack.. The only way to detect heart blockages before they cause symptoms or are detected in conventional tests is to measure the wall thickness of the neck artery or the leg artery. Normally, the wall thickness is less than 0.5mm. If the wall thickness is more than 0.75mm, it is suggestive of underlying heart blockages and if it is more than 1mm, it is suggestive of blockages in all three arteries of the heart.. Any thickness of more than 1mm is called as a plaque and a plaque area calculated by high resolution ultrasound is a new marker for heart blockages, progression as well as regression.. If the artery wall ...

A standard echocardiogram is a simple, painless and safe procedure. There are no side effects from the scan, although the lubricating gel may feel cold and you may experience some minor discomfort when the electrodes are removed from your skin at the end of the test.. Unlike some other tests and scans, such as X-rays and computerised tomography (CT) scans, no radiation is used during an echocardiogram. However, there are some risks associated with the less common types of echocardiogram.. You may find the TOE procedure uncomfortable and your throat may feel sore for a few hours afterwards. You wont be able to drive for 24 hours after the test as you may still feel drowsy from the sedative. Theres also a small chance of the probe damaging your throat..

Dr. Sharma conveys reasonable concerns with regard to our findings from the ACIC (Advanced Cardiovascular Imaging Consortium) registry (1). We agree that using a cutoff of ,50% stenosis rather than ,70% stenosis is a limitation of this study, as clarified in the paper. Stress tests in this study were varied and consisted of 3 different modalities that have varied strengths and limitations. For example, although stress echocardiography performs best to detect ischemia in territories with hemodynamically significant (,70%) stenosis, numerous studies have also assessed the accuracy of this modality for using an angiographic stenosis cutoff of ≥50% as significant (2). Due to its ability to detect flow heterogeneity because of impairment of flow reserve (rather than ischemia), nuclear imaging can pick up ,70% stenosis (3). Hence, a cutoff of ,50% in this mixed bag of stress tests might not be unreasonable.. With respect to accuracy, our findings reflect the limitations of comparing anatomic ...

In this study we showed that the use of second harmonic imaging during dobutamine stress echocardiography improved the accuracy of the detection of viable myocardium in patients with severe left ventricular dysfunction compared with fundamental imaging, DISA-SPECT being used as a reference method. Compared with fundamental imaging, the agreement between dobutamine stress echocardiography and DISA-SPECT on viability assessment increased significantly from 78% (κ = 0.56) to 89% (κ = 0.77) when second harmonic imaging was used (p = 0.001).. Although the use of combined low/high dose dobutamine echocardiography has improved the accuracy of dobutamine stress echocardiography for detecting viability,21 22 there remains some discordance between dobutamine echocardiography and nuclear imaging.23-25 Previous studies have shown that 201thallium classified a significantly higher percentage of segments as viable compared with dobutamine stress echocardiography.7 24 A similar discrepancy was observed ...

To study the effects of Beta-blockers during Dobutamine Stress Echocardiography (DSE) comparing the hemodynamic benefits of an early administration of atropine in patients taking or not Beta-blockers. One hundred and twenty-one patients were submitted to dobutamine stress echocardiography for the investigation of myocardial ischemia. The administration of atropine was randomized into two groups: A or B (early protocol when atropine was administered at 10 and 20 mcg/kg/min of dobutamine, respectively) and C (standard protocol with atropine at 40 mcg/kg/min of dobutamine). Analysis of the effects of Beta-blockers was done regarding the behavior pattern of heart rate and blood pressure, test time, number of conclusive and inconclusive (negative sub-maximum test) results, total doses of atropine and dobutamine, and general complications. Beta-blocked patients who received early atropine (Group A&B) had a significantly lower double product (p = 0.008), a higher mean test time (p = 0.010) and required a
To the Editor:. We first would like to thank Tanimoto et al1 for their study regarding cardiac magnetic resonance and ischemic mitral regurgitation (IMR). They sought to explore the relationship between papillary muscle infarction (detected by postgadolinium cardiac magnetic resonance) and IMR. IMR is still a subject of debate: Its qualification is challenging, and its treatment remains not much evaluated. We believe it would be interesting to argue in regard to Tanimoto et als conclusions. Because IMR is known to be related to left ventricular remodeling and to loading conditions, it probably should be explored by exercise stress echocardiography. We all know that IMR severity, even its reality, might be extremely load dependent. Exercise stress echocardiography has been demonstrated for IMR diagnosis and prognostic evaluation.2 During an exercise, changes in loading conditions might reveal any significant IMR.3 An ongoing European multicentric study has sought to confirm the clinical value of ...

If exercise on a treadmill is not an option (too much stress on the heart) due to a persons medical condition, a doctor may use an intravenous medication called dobutamine. Dobutamine causes the heart to beat faster and will mimic the effects of exercise on the heart.. An echocardiogram is a noninvasive (the skin is not pierced) procedure used to assess the hearts function and structures. During the procedure, a transducer (like a microphone) sends out ultrasonic sound waves at a frequency too high to be heard. When the transducer is placed on the chest at certain locations and angles, the ultrasonic sound waves move through the skin and other body tissues to the heart tissues, where the waves bounce or echo off of the heart structures. The transducer picks up the reflected waves and sends them to a computer. The computer displays the echoes as images of ...

Dual imaging stress echocardiography, combining the evaluation of wall motion and coronary flow reserve (CFR) on the left anterior descending artery (LAD), and computed tomography coronary angiography (CTCA) are established techniques for assessing prognosis in chest pain patients. In this study we compared the prognostic value of the two methods in a cohort of patients with chest pain having suspected coronary artery disease (CAD). A total of 131 patients (76 men; age 68 ± 9 years) with chest pain of unknown origin underwent dipyridamole (up to 0.84 mg/kg over 6 min) stress echo with CFR assessment of LAD by Doppler and CTCA. A CFR ≤ 1.9 was considered abnormal, while | 50% lumen diameter reduction was the criterion for significant CAD at CTCA. Of 131 patients, 34 (26%) had ischemia at stress echo (new wall motion abnormalities), and 56 (43%) had reduced CFR on LAD. Significant coronary stenosis at CTCA was found in 69 (53%) patients. Forty-six patients (84%) with abnormal CFR on LAD showed
The prognostic value of SE in diabetic patients with known or suspected CAD has been previously demonstrated (16-19). However, given their high-risk status for the development of cardiovascular diseases (1-4), diabetic patients present with a substantially increased pretest likelihood of adverse outcome. Thus, to verify whether the test conveys similar prognostic information in diabetic and nondiabetic patients is of primary clinical relevance. With this aim in mind, we analyzed the data of a large cohort of patients with and without diabetes mellitus who were referred for pharmacological SE. Diabetic patients had a higher risk profile, as demonstrated in the more advanced age and higher prevalence of CAD, hypertension, resting wall motion abnormalities, and ischemic or scar echocardiographic pattern. Moreover, they more frequently underwent coronary interventions and fared worse than nondiabetic patients independently of the presence of a known CAD. Diabetic patients with suspected CAD had a ...

This type of echocardiogram utilizes a special medication called dobutamine. Essentially, this medication mimics regular echocardiograms, stimulating your heart so it appears that you are exercising. The dobutamine allows cardiologists to:. ...
A stress echo is a test that takes pictures of the heart with the use of a probe placed outside your chest wall while your heart is working hard. To stress the heart, youll be given an intravenous medication (Dobutamine) that will make your heart beat harder and faster just like it would during exercise. ​​. The pictures taken before, during and after your heart is stressed are displayed on the ultrasound monitor and are recorded on a disk for review and comparison. A dobutamine stress echo is performed by a sonographer and interpreted by a cardiologist ...

Objectives: To examine the feasibility of application of the recent ACCF/ASE Appropriateness Criteria for Echocardiography.. Methods: Indications for transthoracic (TTE) and transesophageal echocardiography(TEE) were retrospectively determined by physician chart review in consecutive patients at a tertiary care center, and were classified according to the guidelines as appropriate (A), inappropriate (I), or uncertain (U), or, for situations not addressed in the document, as not classifiable (NC). To assess interobserver agreement, 63 studies were independently reviewed by 2 physicians.. Results: We included 493 consecutive pts who underwent echo: 176 (35%) outpatient TTE, 131 (26%) inpatient TTE, 95 (19%) outpatient TEE, and 91 (18%) inpatient TEE. Of all studies, 420 (85%) were A, 25 (5%) I, 1 (0.2%) U, and 47 (10%) NC. I and NC studies were more commonly TTE (7%, 13%, respectively) compared to TEE (2%, 5%) (p, 0.001). I studies were more common in outpatients than inpatients (9% vs 2%, p, ...
OBJECTIVE-This study sought to determine whether stress echocardiography using exercise (when feasible) or dobutamine echo could be used to predict mortality in patients with diabetes.. RESEARCH DESIGN AND METHODS-Stress echo was performed in 937 patients with diabetes (aged 59 ± 13 years, 529 men) for symptom evaluation (42%) and follow-up of known coronary artery disease (CAD) (58%). Stress echocardiography using exercise was performed in 333 patients able to exercise maximally, and dobutamine echo using a standard dobutamine stress was used in 604 patients. Patients were followed for ≤9 years (mean 3.9 ± 2.3) for all-cause mortality.. RESULTS-Normal studies were obtained in 567 (60%) patients; 29% had resting left ventricular (LV) dysfunction, and 25% had ischemia. Abnormalities were confined to one territory in 183 (20%) patients and to multiple territories in 187 (20%) patients. Death (in 275 [29%] patients) was predicted by referral for pharmacologic stress (hazard ratio [HR] 3.94, P , ...

By Bob Hobbs, APRN, MBA. With Healthcare reform focusing on more preventative services we wanted to discuss a diagnostics/screening test that has been around for years. The stress test was developed in 1928 and has been used since 1929 to help diagnose and screen patients with various heart related problems. It has evolved into a cardiac investigative test. Technological improvements over the years have led to the decrease in costs of performing this test which makes it available to more facilities. Patients are being screened now at the primary care level. In this article we will discuss the basics of a cardiopulmonary exercise stress test (CPET), discuss how the results of the test are used, and which patients should be asking their provider more about this test.. What is the CPET Stress Test?. While there are several types of stress tests that are performed such as a Dobutamine or Adenosine Stress Test (chemical stress test for those patients unable to exercise), stress echocardiogram, and ...
In an effort to establish my risk of cardiovascular disease, I recently underwent whats known as stress echocardiography (stress echo test) with Dr Jason Kaplan at Macquarie University Clinic. This was following my first lot of tests (calcium score and pulse wave analysis amongst others), which indicated I have a very low risk of developing cardiovascular disease for the time being. Watch my interview with Jason below, or scroll down to read my notes. The first steps in a stress echo test The first part of the stress echo test is having real-time ultrasound pictures taken of your heart from.... Read More ...

About 1 month or so ago I started having sharp stabbing chest pains. The pains were near and around the heart. My family physician diagnosed me with reflux....after treatment, we concluded it was an incorrect diagnosis. I have been to the ER 3 times for this chest pain. The day that the first pains came about I was just sitting on the couch watching tv and the pain radiated from my back shoulder blade to my chest, along with shortness of breath. Ive had blood work, EKGs, ABG, CT w/dye of my heart at the ERs all came back fine. Next stop was the cardiologist. He did an EKG, echocardiogram & a Stress Echocardiogram. The echo showed that I have mild tricuspid regurgitation and mild mitral valve regurgitation. I could not get my heart rate up as high as he wanted me to during my stress echo. So when they tried to do the ultrasound of my heart, my heart rate dropped quickly. He put me on 25 mg of toprol-xl 1x daily. My blood pressure has always been around 120/80 and now with the toprol it has ...
