Background: Despite the increasing magnitude and impact, there are limited data available on the clinical management and in-hospital outcomes of patients who have diabetes mellitus (DM) and chronic kidney disease (CKD) at the time of hospitalization for acute myocardial infarction (AMI). The objectives of our population-based observational study in residents of central Massachusetts were to describe decade-long trends (1999–2009) in the characteristics, in-hospital management, and hospital outcomes of AMI patients with and without these comorbidities.
Methods: We reviewed the medical records of 6,018 persons who were hospitalized for AMI on a biennial basis between 1999 and 2009 at all eleven medical centers in central Massachusetts. Our sample consisted of the following four groups: DM with CKD (n=587), CKD without DM (n=524), DM without CKD (n=1,442), and non-DM/non-CKD (n=3,465).
Results: Diabetic patients with CKD were more likely to have a higher prevalence of previously diagnosed comorbidities, to have developed heart failure acutely, and to have a longer hospital stay compared with non-DM/non-CKD patients. Between 1999 and 2009, there were marked increases in the prescribing of beta-blockers, statins, and aspirin for patients with CKD and DM as compared to those without these comorbidities. In-hospital death rates remained unchanged in patients with DM and CKD, while they declined markedly in patients with CKD without DM (20.2% dying in 1999; 11.3% dying in 2009).
Conclusion: Despite increases in the prescribing of effective cardiac medications, AMI patients with DM and CKD continue to experience high in-hospital death rates.
