Background: Alterations in glucose metabolism have been reported as risk and poor prognostic factors for acute myocardial infarction (AMI); however in Latin-American population this information is limited. Thus, an evaluation was performed on the association between glycaemic status and short- and long-term outcomes in patients with a first AMI.
Methods: A multicentre, prospective, observational, cohort study was conducted in 8 hospitals from Colombia and Ecuador.
Results: A total of 439 patients with confirmed AMI were included, of which 305 (69.5%) had prediabetes or type2 diabetes mellitus (DM2). Compared with normal glycaemia group, patients with known DM2 had greater risk of prolonged hospital stay (HR: 2.60, 95%CI: 1.38-4.92, P=.003), Killip class iii/iv (HR: 9.46, 95%CI: 2.20-40.62, P=.002), and in-hospital heart failure (HR: 10.76, 95%CI: 3.37-34.31, P<.001). Patients with prediabetes, new DM2, and known DM2 showed higher rates of major adverse cardiovascular events after 3years follow-up.
Conclusion: Glucose metabolism abnormalities have an important significance in the short- and long-term prognosis in Latin-American patients that survive a first AMI.
