Impaired Orthostatic Tolerance after Bed Rest in Patients with Myocardial Infarction

Abstract
In the presence of coronary atherosclerosis, systemic hypotension may result in acute ischemic damage to the myocardium. In 22 patients convalescing from acute myocardial infarction, orthostatic tolerance was studied by means of measurements of heart rate and blood pressure after bed rest. Tests were repeated after full mobilization in 16 patients.
