Dobutamine or adenosine stress test:This is for people unable to exercise. You’ll take a drug to make the heart respond as if you wereexercising. This way, the doctor can still determine if there are blockages in thearteries. Stressechocardiogram:Anechocardiogram(often called "echo") is a ...

Before starting an exercise test, a baseline echocardiogram is performed in the left lateral decubitus position for an initial assessment, with 2D and M-mode image acquisition in at least four planes, i.e., parasternal long axis, parasternal short axis, apical four-chamber, and apical two-...
Assessment of patients with low-risk chest pain in the emergency department: Head-to-head comparison of exercise stress echocardiography and exercise myocardial SPECTdoi:10.1016/j.ahj.2004.09.048Objectives The aim of the study was to compare head-to-head the performance of exercise tolerance test–...
A dobutamine stress test works by mimicking the heart's response to exercise without the need for physical exertion. While a...
Number of stress echocardiograms (SE) that would have been authorized (green bars) or deferred (pink bars) according to the guidelines of (A) radiology benefits managers (RBM) #1 and (B) RBM #2, stratified according to their appropriateness rating (combined appropriate and uncertain vs. inappr...
17 One of the widely used parameters in sECG prognosis is the Duke treadmill score (DTS), which factors in exercise time, maximum ST depression and presence of angina during test. Those with a DTS of 5 or above had excellent 5-year prognosis whereas those with a DTS worse than −11 ...
and pulmonary vascular capacitance determined by cardiac catheterization is a strong predictor of survival in patients with pulmonary hypertension. Pulmonary Vascular Capacitance can be derived noninvasively from a comprehensive 3 D and Doppler echocardiogram. Using the peak systolic tricuspid regurgitation vel...
Echocardiograms were recorded using a Vevo-3100 ultrasound system (Visual Sonics, Toronto, Ontario, Canada) equipped with a 70-MHz transducer. Protein interaction was analyzed using immunofluorescent imaging and biochemical coimmunoprecipitation. Peak intensity of Cav1.2 at t-tubules is quantified using...
In a retrospective review of nearly 2000 exercise stress echocardiograms, inducible ischemia was not associated with death, but nearly half of the study population was younger than 50 years [16]. A different study in patients aged 50–75 years which included over 600 relatively healthy patients ...
