Abstract [en]

Background and Purpose Acute myocardial infarction (AMI) increases the risk of ischemic stroke, and mortality among these patients is high. Here, we aimed to estimate the 1-year mortality reliably after AMI complicated by ischemic stroke. We also aimed to identify trends over time for mortality during 1998-2008, as well as factors that predicted increased or decreased mortality. Methods Data for 173 233 unselected patients with AMI were collected from the Swedish Register of Information and Knowledge about Swedish Heart Intensive Care Admissions registry for 1998-2008. Specifically, we analyzed 1-year follow-up and mortality data for patients with AMI with and without ischemic stroke. Kaplan-Meyer analysis was used to analyze mortality trends over time, and Cox regression analysis was used to identify uni- and multivariate predictors of mortality. Results The 1-year mortality was 36.5% for AMI complicated by ischemic stroke and 18.3% for AMI without stroke. Mortality decreased over time in patients with and without ischemic stroke. The absolute decreases in mortality were 9.4% and 7.5%, respectively. Reperfusion and secondary preventive therapies were associated with a decreased mortality rate. Conclusions Mortality after AMI complicated by an ischemic stroke is very high but decreased from 1998 to 2008. The increased use of evidence-based therapies explains the improved prognosis.
