Abstract

Background: Managed Care in Acute Myocardial Infarction (MC-AMI) is a program introduced in Poland aimed at comprehensive, scheduled, and supervised care for AMI patients to improve long-term prognosis. Aims: Our study aimed to compare 24-month mortality and the incidence of major cardiovascular events (MACE: a composite of death, recurrent MI, and hospitalization for heart failure) in a cohort of AMI patients treated in the MC-AMI era (intention-to-treat analysis) vs. similar population treated before the MC-AMI era. Methods: We analyzed 2323 consecutive patients with AMI: 1261 patients enrolled in the MC-AMI era (study group) and 1062 patients treated 12 months before the MC-AMI era (control group). In the study group, 57% of patients participated in MC-AMI while 43% of patients remained under standard care. The patients were followed up for 24 months. Mortality and MACE were recorded. Results: Treatment in the MC-AMI era was related to a 30% reduction in all-cause mortality and a 14% reduction of MACE although it was not related to the reduction of hospitalization for heart failure (HF) or AMI in 24 months. The 24-month survival rate was the highest in MC-AMI enrolled patients while patients treated in the MC-AMI era but not enrolled had a similar prognosis to those treated before the MC-AMI era. Multivariable Cox regression analysis revealed the MC-AMI era to be inversely associated with mortality in 24-month follow-up (hazard ratio [HR], 0.49; 95% confidence interval [Cl], 0.38–0.65; P <0.001). Conclusions: AMI treatment in the MC-AMI era reduces 24-month mortality and MACE. Moreover, AMI treatment in MC-AMI is inversely related to mortality, MACE, and hospitalization for HF. The effect is pronounced in patients enrolled in MC-AMI.
