Effects on the left ventricular diastolic dysfunction of a cardiac rehabilitation program in chronic heart failure patients

Abstract Funding Acknowledgements Type of funding sources: None. PURPOSE The aim the present study is to evaluate impact a cardiac rehabilitation program on diastolic dysfunction, ejection fraction (EF) left ventricular and volume index atrium comparing 2 groups: those with restricted EF (<40%) intermediate preserved (≥ 40%). METHODS In 41 stable CHF patients (N = 41; 56 ±10 years [mean ± SD], 34 males 7 females) participated in an exercise (3 sessions week). Only 38 them completed form circuit-interval aerobic training, adjusted according 70–80% heart rate reserve, for period 3 months. A detailed echocardiogram was performed before immediately after program, focusing dysfunction assessment ventricular. RESULTS At end three months stage significantly decreased (from 1.45+/- 0.72 1.08 +/-0.67, p .000). LV increased 34.97+/-10.66 36.68 +/-10.52, .002). addition, there significant decrease E/E" RVSP 9.37+/-3.54 8.47+/-3.34 from 28.44+/-6.86mmHg 27.38+/-5.87 mmHg, =.033 =.030, respectively). Finally, atrial average e" had no decrease. CONCLUSIONS Circuit training improved both systolic but repercussion volume. From this it concluded that can have improvement especially group, mechanism essential pathophysiology CHF. Table 1 PairedDifferences t df Sig. (2-tailed) Mean Std.
