Efficacy of a cardiac rehabilitation program in a municipal sports center compared to the hospital program: randomized controlled trial eCARCEX.

BACKGROUND

This study aimed to analyze the effects of an outpatient cardiac rehabilitation program in a municipal sports center on functional capacity and adherence to physical exercise - among other variables - compared to an in-hospital program.

METHODS

Randomized clinical trial that included two parallel groups of acute coronary syndrome patients who performed a cardiac rehabilitation program that consisted of moderate physical exercise intervals along with learning healthy habits in a municipal sports center (experimental group) and in a tertiary hospital (control group) between September 2019 and June 2020. We collected the following data: compliance, anthropometrical, clinical, psychological variables, diet and tobacco habits, strength and functional capacity from ergospirometry.

RESULTS

Twenty-two patients completed the cardiac rehabilitation program (experimental group=12, control group=10). Significant improvement was observed for cholesterol, the sit-and-stand test, cardiac frequency in VT1 and VT2, and watts in VT1 in the control group, and for HDL-cholesterol, triglycerides, the sit-and-stand test, and frequency, and watts in VT1 in the experimental group. Better achievement was found in the control group for cardiac frequency in VT2 (11.17 vs 2.88 bpm) and in EG for HDL-cholesterol (11.0 vs 0.63 mg/dL).

CONCLUSIONS

We are unable to determine the effectiveness of the out-of-hospital cardiac rehabilitation program due to a lack of power (high number of withdrawals caused by COVID-19 lockdown). However, the experimented group achieved higher HDL-cholesterol levels, while cardiac frequency in VT2 was higher in the control group.
