Insights
Cardiac rehabilitation significantly improves exercise capacity in ST-segment elevation myocardial infarction (STEMI) patients post-hospitalization. Benefits were observed across diverse patient groups, highlighting its importance for long-term recovery.
Area of Science:
- Cardiology
- Rehabilitation Medicine
- Public Health
Background:
- High inpatient mortality reduction in STEMI interventions in Poland.
- Increased mortality rates observed within 3 years post-discharge.
- Need for continued cardiac rehabilitation to reduce out-of-hospital mortality.
Purpose of the Study:
- Evaluate cardiac rehabilitation's effect on exercise capacity in STEMI patients.
- Analyze benefits based on age, gender, BMI, ejection fraction (EF), diabetes, and nicotine dependence.
- Assess effectiveness using exercise ECG stress tests and 6-minute walk tests.
Main Methods:
- Retrospective study of 100 randomly selected STEMI patients.
- Inclusion criteria: aged 40-75, BMI ≤ 40 kg/m², controlled hypertension, no anemia or pulmonary comorbidities.
- Pre- and post-rehabilitation assessments of exercise capacity.
Main Results:
- Significant increase in exercise capacity: +1 MET on stress ECG, +75.4 m on 6-min walk test.
- Improvements observed irrespective of gender, age, BMI, and nicotine dependence.
- Greatest benefits noted in nicotine-dependent individuals, males, younger patients (≤55), and those with reduced EF (<50%).
Conclusions:
- All STEMI patients can benefit from cardiac rehabilitation.
- Cardiac rehabilitation is crucial for improving long-term outcomes post-STEMI.
- Personalized rehabilitation strategies may further optimize benefits for specific patient subgroups.
Abstract:
Background: The efficacy of interventions in ST-segment elevation myocardial infarction (STEMI) assessed by a decrease in inpatient mortality in Poland is very high. However, a rise in mortality rate is recorded within 3 years of the discharge from the intervention centre. In order to reduce out-of-hospital mortality, the treatment should be continued with cardiac rehabilitation after hospitalization. The aim of this retrospective study was to evaluate the effect of cardiac rehabilitation on exercise capacity increase patients with STEMI with regard to their age, gender, Body Mass Index (BMI), ejection fraction (EF), concomitant diabetes and nicotine dependence. The effectiveness of cardiac rehabilitation was assessed by exercise ECG (electrocardiogram) stress test or the 6-min walk test, prior to and after cardiac rehabilitation completion. Methods: The study group included 100 randomly selected patients undergoing cardiac rehabilitation after STEMI, aged 40-75 years, with BMI ≤ 40 kg/m2, with controlled arterial hypertension, without anemia and any pulmonary comorbidities. Results: The study patients' exercise capacity was observed to have increased significantly (+1 metabolic equivalent (MET) in exercise ECG stress test and +75.4 m in the 6-min walk test) regardless of their gender, age, BMI and nicotine dependence. Conclusions: This study proved that every patient with STEMI could benefit from cardiac rehabilitation. Nicotine-dependents, males, patients aged ≤55 and those with reduced EF (<50%) were found to have benefitted most substantially.
