Q. What do you know by Hemodynamic Responses?

Reduced exercise capacity roughly reflects impaired LV function, and may contribute its prognostic value to this association. Completing a workload of at least 3 MET implies a favorable prognosis even if ST-segment depression or ventricular arrhythmias occurred. Excluding patients with clinical heart failure, it is found that a maximum workload of less then 4 METS at 3 weeks after infarction, is a risk factor for future cardiac events. Inadequate blood pressure response (defined as an increase of 10mm or less in systolic blood pressure with a peak systolic blood pressure of 140mm or less, or a fall of greater than 20mm in systolic pressure from peak systolic blood pressure) also appeared predictive of coronary events and seemed to correlate with exercise duration.
