However, the effects of aerobic training (AT) versus resistance training (RT) on cardiac function in patients with heart failure with reduced ejection fraction are not well defined. The aim of this study was to evaluate the impact of these exercise modalities on echocardiographic parameters.
Participants with stable heart failure with reduced ejection fraction (ejection fraction < 50%) were randomized to 12 weeks of AT, RT, or untrained control. Exercise was performed at matched relative intensities of each training modality (50%–70% of maximum). Echocardiography and cardiopulmonary exercise testing were performed at baseline and after 12 weeks of training.
Thirty-eight participants were randomized, and 12 in each group completed the intervention (mean age, 61.5 ± 1.7 years; 89% men). Peak oxygen consumption increased from 14.5 ± 1.3 to 17.2 ± 1.6 ml · min−1 · kg−1 after AT and from 13.7 ± 1.2 to 16.4 ± 1.1 ml · min−1 · kg−1 after RT (P < .001 for both). In the AT group, there was a decrease in septal e′ (from 0.052 ± 0.004 to 0.041 ± 0.004 m/sec) and increases in E/e′ ratio (from 18.2 ± 3.1 to 23.8 ± 3.5), left atrial volume (from 86 ± 9 to 99 ± 10 mL), and right ventricular end-diastolic area (from 18 ± 1 to 20 ± 1 cm2; P < .05 for all), but these were unchanged in the control and RT groups. There were no significant changes in left ventricular diameters or volumes or right ventricular fractional area change after exercise.
There is a differential effect of AT versus RT on some echocardiographic parameters in patients with heart failure with reduced ejection fraction. AT was associated with evidence of worsening myocardial diastolic function, whereas this was not apparent after RT. Further studies are indicated to investigate the long-term clinical significance of these adaptations.
