Cardiovascular rehabilitation represents a very important measure in post myocardial infarction patients for both, improving their quality of life and preventing other acute cardiovascular events. It is important to accurately assess functional capacity of patients after acute coronary events, in order to optimize the results of cardiac rehabilitation program. Cardiopulmonary exercise testing (CPET) represents the gold standard in functional capacity assessment. We present 3 clinical cases of post STEMI patients, with coronary revascularization interventions, addressed to cardiovascular rehabilitation. They underwent CPET evaluation at baseline and during rehabilitation program. This method proved important utility for individualization of cardiovascular rehabilitation program, as well as for monitoring the long term evolution after myocardial infarction.

Cardiac rehabilitation (CR) is indicated in all patients after acute myocardial infarction (AMI) to improve prognosis and exercise capacity (EC). Previous studies reported that up to a third of patients did not improve their EC after CR (non-responders). Our aim was to assess the cardiac and peripheral mechanisms of EC improvement after CR using combined exercise echocardiography and cardiopulmonary exercise testing (CPET-SE). The responders included patients with an improved EC assessed as a rise in peak oxygen uptake (VO2) ≥ 1 mL/kg/min. Peripheral oxygen extraction was calculated as arteriovenous oxygen difference (A-VO2Diff). Out of 41 patients (67% male, mean age 57.5 ± 10 years) after AMI with left ventricular ejection fraction (LVEF) ≥ 40%, 73% improved their EC. In responders, peak VO2 improved by 27% from 17.9 ± 5.2 mL/kg/min to 22.7 ± 5.1 mL/kg/min, p < 0.001, while non-responders had a non-significant 5% decrease in peak VO2. In the responder group, the peak exercise heart rate, early diastolic myocardial velocity at peak exercise, LVEF at rest and at peak exercise, and A-VO2Diff at peak exercise increased, the minute ventilation to carbon dioxide production slope decreased, but the stroke volume and cardiac index were unchanged after CR. Non-responders had no changes in assessed parameters. EC improvement after CR of patients with preserved LVEF after AMI is associated with an increased heart rate response and better peripheral oxygen extraction during exercise.
