Managed Care after Acute Myocardial Infarction (MC-AMI) – a Poland’s nationwide program of comprehensive post-MI care - improves prognosis in 12-month follow-up. Preliminary experience from a single high-volume center

Abstract

BackgroundDespite progress in the treatment of acute myocardial infarction (AMI), long-term prognosis in MI survivors remains a challenge. The Managed Care in Acute Myocardial Infarction (MC-AMI, KOS-zawal) is the first program of a comprehensive, supervised care for patients with AMI to improve long-term prognosis. It includes acute intervention, complex revascularization, cardiac rehabilitation (CR), outpatient follow-up, and prevention of SCD. Our aim was to assess the relation between participation in MC-AMI and major adverse cardiovascular and cerebrovascular events (MACCE) in 12-month follow-up. Methods and resultsIn this single-center, retrospective analysis we compared 719 patients participating in MC-AMI and compared them to 1130 subjects in the control group. After propensity score matching, two groups of 529 subjects each were compared.MC-AMI was related with MACCE reduction by 40% in a 12-month observation. Participants of MC-AMI had a higher adherence to cardiac rehabilitation (98 vs. 14%), higher rate of scheduled revascularisation (coronary artery bypass grafting: 9.8% vs. 4.9%, p ≪ 0.001; elective percutaneous coronary intervention: 3.0% vs 2.1%, p ≪ 0.05) and ICD implantation (2.8% vs. 0.6%, p ≪ 0.05) compared to control.Multivariable Cox regression analysis revealed MC-AMI to be inversely associated with the occurrence of MACCE (HR = 0.500, 95% Cl 0.349–0.718, p ≪ 0.001). Besides, older age, diabetes mellitus, hyperlipidemia, prior PAD, previous UA, and lower LVEF were significantly associated with the primary endpoint. ConclusionsMC-AMI is the first program of comprehensive care for AMI patients. MC-AMI improves prognosis by increasing the rate of patients undergoing CR, complete revascularization and ICD implantation, thus reducing MACCE.
