Proportion of Low-Risk Survivors of Acute MI Increased From 2001 to 2011
The number of low-risk survivors of acute myocardial infarction increased during the last decade.
(HealthDay News) — The proportion of low-risk survivors of acute myocardial infarction (MI) increased from 2001 to 2011, and characteristics include younger age, male gender, and being married, according to a study published in The American Journal of Cardiology.
Mayra Tisminetzky, MD, PhD, from the University of Massachusetts Medical School in Worcester, and colleagues reviewed data from 4268 residents of the Worcester metropolitan area discharged after an acute MI from 3 central Massachusetts hospitals from 2001 to 2011.
The researchers found that 43.5% of patients were classified as low-risk survivors of an acute MI from 2001 to 2011, 12.3% died, and 44.2% had at least 1 rehospitalization during the following year. During the study period there was an increase in the proportion of low-risk survivors from 42.6% to 46.4% and a decrease in the proportion of those who died within a year after hospital discharge from 14.3% to 10.5%.
After adjustment for multiple patient characteristics, the likelihood of being classified as a low-risk acute MI survivor was increased for younger persons (≤65 years), men, married patients, patients not presenting with multimorbidities, and patients who did not develop in-hospital clinical complications.
"Identifying low-risk survivors of an acute MI may help health care providers to focus more intensive efforts and interventions on those at higher risk for dying and/or being readmitted to the hospital during the post-discharge transition period after an acute MI," the researchers wrote.
