A resting echocardiogram is obtained prior to stress. The ultrasound images obtained are similar to the ones obtained during a full surface echocardiogram, commonly referred to as transthoracic echocardiogram. The patient is subjected to stress in the form of exercise or chemically (often dobutamine). After the target heart rate is achieved ...
Dobutamine is a medication used in the treatment of cardiogenic shock (as a result of inadequate tissue perfusion) and severe heart failure. [ 2][ 3] It may also be used in certain types of cardiac stress tests. [ 2] It is given by IV only, as an injection into a vein or intraosseous as a continuous infusion. [ 2]
Tests include coronary angiography, intravascular ultrasound, dobutamine stress echocardiography, positron emission tomography, computed tomographic angiography (CT angiography) and several biomarkers. [2] Statins and aspirin are commenced early after transplantation and on detection of CAV. [2]
Peripartum cardiomyopathy (PPCM) is a form of dilated cardiomyopathy that is defined as a deterioration in cardiac function presenting typically between the last month of pregnancy and up to six months postpartum. As with other forms of dilated cardiomyopathy, PPCM involves systolic dysfunction of the heart with a decrease of the left ...
Echocardiography: A wall motion abnormality at rest which improves during a low-dose dobutamine stress test is classified as "hibernating myocardium." Low dose dobutamine stimulates contractile function and thus helps to predict functional recovery after revascularization. Cardiac magnetic resonance: The most frequently used MR contrast agents ...
Strain rate imaging. Strain rate imaging is a method in echocardiography ( medical ultrasound) for measuring regional or global deformation of the myocardium (heart muscle). The term "deformation" refers to the myocardium changing shape and dimensions during the cardiac cycle. If there is myocardial ischemia, or there has been a myocardial ...
Making the diagnosis of HCM often involves a family history or pedigree, an electrocardiogram, echocardiogram, and stress testing. [7] Genetic testing may also be done. [ 7 ] HCM can be distinguished from other inherited causes of cardiomyopathy by its autosomal dominant pattern, whereas Fabry disease is X-linked, and Friedreich's ataxia is ...
Coronary ischemia, myocardial ischemia, [ 1] or cardiac ischemia, [ 2] is a medical term for abnormally reduced blood flow in the coronary circulation through the coronary arteries. [ 3] Coronary ischemia is linked to heart disease, and heart attacks. [ 4] Coronary arteries deliver oxygen-rich blood to the heart muscle. [ 5]
