Insights
Community-based cardiac rehabilitation (CR) significantly improved outcomes for acute myocardial infarction (AMI) patients post-percutaneous coronary intervention (PCI). This safe and effective program enhanced cardiac function, exercise capacity, and reduced adverse events, improving patients' quality of life.
Area of Science:
- Cardiology
- Rehabilitation Medicine
- Public Health
Background:
- Acute myocardial infarction (AMI) remains a primary cause of mortality and disability globally.
- Cardiac rehabilitation (CR) development in AMI patients, particularly post-percutaneous coronary intervention (PCI), has been slow.
- This study evaluates the safety and efficacy of community-based CR for AMI patients after PCI.
Purpose of the Study:
- To assess the effectiveness of community-based cardiac rehabilitation in improving clinical outcomes for AMI patients post-PCI.
- To determine if CR enhances cardiac function, exercise tolerance, and cardiovascular risk factors in this population.
Main Methods:
- 130 ST-segment elevated myocardial infarction (STEMI) patients post-PCI were randomized into a community-based rehabilitation group (n=65) or a control group (n=65).
- Interventions included monitoring cardiac function, 6-minute walk distance, exercise metrics, and cardiovascular risk factors before and after the rehabilitation program.
- Statistical analysis was performed using SPSS 16.0.
Main Results:
- The rehabilitation group demonstrated significant improvements in reducing recurrent angina and readmission rates (P < .01).
- Left ventricular ejection fraction (LVEF) improved significantly in both phase II and III cardiac rehabilitation (P < .01).
- The rehabilitation group showed better cardiovascular risk factor management and improved exercise tolerance (6-minute walk distance, aerobic exercise time, steps) compared to the control group (P < .05).
Conclusions:
- Community-based CR, utilizing simple and safe exercises, effectively enhances the quality of life for AMI patients post-PCI.
- The program leads to increased cardiac ejection fraction, improved exercise tolerance, and better physical status.
- Successful implementation relies on collaboration between cardiologists, general practitioners, patients, and their families.
Background:
Acute myocardial infarction (AMI) is one of the leading causes of death and physical disability worldwide. However, the development of community- based cardiac rehabilitation (CR) in AMI patients is hysteretic. Here, we aimed to evaluate the safety and efficacy of CR applied in the community in AMI patients who underwent percutaneous coronary intervention (PCI).
Methods:
A total of 130 ST-segment elevated myocardial infarction (STEMI) patients after PCI were randomly divided into 2 groups in the community, rehabilitation group (n = 65) and control group (n = 65). Cardiac function, a 6-minute walk distance, exercise time and steps, cardiovascular risk factors were monitored respectively and compared before and after the intervention of 2 groups. The software of EpiData 3.1 was used to input research data and SPSS16.0 was used for statistical analysis.
Results:
After a planned rehabilitation intervention, the rehabilitation group showed better results than the control group. The rehabilitation group had a significant improvement in recurrence angina and readmission (P < .01). Left ventricular ejection fraction (LVEF) of rehabilitation group showed improvement in phase II (t = 4.963, P < .01) and phase III (t = 11.802, P < .01), and the New York Heart Association (NYHA) classification was recovered within class II. There was a significant difference compared with before (Z = 7.238, P < .01). Six minutes walking distance, aerobic exercise time, and steps all achieved rehabilitation requirements in rehabilitation group in phase II and III, there existed distinct variation between 2 phases. Rehabilitation group had a better result in cardiovascular risk factors than control group (P < .05).
Conclusion:
Community-based CR after PCI through simple but safe exercise methods can improve the AMI patient's living quality, which includes increasing cardiac ejection fraction, exercise tolerance, and physical status. It must be emphasized that the good result should be established by the foundation of close cooperation between cardiologists and general practitioners, also the importance of cooperation of patients and their families should not be ignored. The rehabilitation program we used is feasible, safe, and effective.
