The long-term benefit of a cardiac rehabilitation program after myocardial infarction in patients under the Managed Care for Acute Myocardial Infarction Survivors (MACAMIS) program in Poland: A single-center study.

ABSTRACT

BACKGROUND: The Managed Care for Acute Myocardial Infarction Survivors (MACAMIS) program introduced for patients after myocardial infarction (MI) consists of 4 modules including early cardiac rehabilitation (CR). AIMS: We compared the impact of CR on survival of patients after MI included in the MACAMIS program. METHODS: Patients in MACAMIS were divided into subgroups based on being qualified or not qual-ified for CR and on whether they completed or failed to complete CR. We evaluated one-, two-, and three-year mortality. RESULTS: Of 244 patients in MACAMIS, 174 patients were qualified for CR. They were younger, had less advanced coronary artery disease (CAD), higher ejection fraction (EF), and fewer comorbidities. Finally, 102 (58.6%) patients completed CR. These patients were younger and more likely to have STEMI; they were more often treated invasively, with no differences in comorbidity burden. The survival rates at one, two, and three years were 93.6%, 87.8%, and 65.0%, respectively. Patients who qualified for CR had a better prognosis. The mortality rates at one, two, and three years were 2.38% vs. 16.18% (P = 0.0003), 6.71% vs. 25.4% (P = 0.002), and 26.87% vs. 51.35% (P = 0.01), respectively. Patients who completed CR, again, had a significantly better prognosis. The mortality rate was 1% vs. 10.29% (P = 0.009), 4.17% vs. 17.56% (P = 0.002), and 23.33% vs. 40.54% (P = 0.09) in analyzed periods. The only independent factors related to survival were completion of CR and number of comorbidities. CONCLUSIONS: Patients with MI in the MACAMIS program had better prognosis when participating in CR. After completing the MACAMIS program, increased mortality was observed in the following years. Despite the flexibility of the CR program, the proportion of patients who qualified and completed CR remained low.
