Handgrip in Acute Myocardial Infarction

with acute myocardial infarction had a significant (P < 0.005) elevation of 5.4 ± 1.3 mm Hg in the pulmonary arterial diastolic or pulmonary wedge pressure. This may be a result of either increased left ventricular stiffness or decreased myocardial functional reserve. In the setting of acute myocardial infarction, patients with normal left ventricular filling pressures have abnormal ventricular performance. Isometric effort is poorly tolerated and should be avoided. increase of the end-systolic volume with reduction in ejection fraction.9”#{176} This study was undertaken to evaluate the response of patients with acute myocardial infarction and normal resting left ventricular filling pressure to a measured amount of isometric stress. This approach was taken in an attempt to unmask an underlying abnormal hemodynamic state.
