Abstract

Background: The study’s aim was to examine the effect of exercise training on left ventricular diastolic function (LVDF) and whether LVDF could predict an improvement in exercise capacity (EC) in post-myocardial infarction patients.
Methods: Forty-eight males, aged 56.4 ± 7.2 years, with preserved left ventricular systolic function (LVSF) and mild diastolic dysfunction (the ratio of transmitral early left ventricular filling velocity to early diastolic mitral annulus velocity E/E’ > 8 as the average of the septal and lateral annulus velocities), were assigned to either a training group (TG, n = 32) or controls (n = 16). Before, and at the end of the study, all patients underwent a cardiopulmonary test and echocardiography with tissue Doppler imaging (TDI).
Results: After a 4.5-month training program, maximal oxygen consumption increased significantly in TG (26.66 ± 3.88 vs. 28.79 ± 5.00 mL/kg/min, p < 0.0001). TDI-derived E/E’ did not change after the training program. After dividing TG according to septal E/E’s > 10 and < 10 and lateral E/E’l > 8 and < 8, exercise capacity improved significantly only in patients with E/E’s < 10 and E/E’l < 8.
Conclusions: A 4.5-month training program in post-myocardial infarction patients with preserved LVSF and mild diastolic dysfunction led to improved exercise capacity only in TG. The diastolic function did not change significantly. The improvement in exercise capacity was significantly greater in patients with a better LVDF measured by TDI.
