Exercise Test
- Current status of stress echocardiography in the diagnosis of coronary artery disease
Electrocardiography with exercise or pharmacologic stress is gaining clinical acceptance, but its accuracy depends on the expertise of the people who perform it.
- Stress echocardiography: its emerging role in identifying viable myocardium
In patients with chronic ischemia or left ventricular systolic dysfunction, this test can indicate whether the damaged myocardium is still viable and, therefore, whether revascularization would be beneficial.
- Cardiopulmonary exercise testing in patients with chronic obstructive pulmonary disease
Defining the etiology of dyspnea, evaluating impairment, and assessing the response to therapy are among the current indications.
- Atrial natriuretic factor and catecholamine levels during exercise in patients with and without coronary artery disease
In coronary artery disease, exercise-induced myocardial ischemia does not produce further release of ANF, suggesting that the cause of ANF release is not ischemia itself, but left ventricular dysfunction leading to increases in intracardiac pressures.
