Myocardial infarction increases incidence of heart failure

Recent research has revealed that 1 in 4 patients will develop heart failure within four years of their first heart attack. The results of prospective study, presented at Heart Failure 2016 and the 3rd World Congress on Acute Heart Failure,  included nearly 25, 000 patients and identified several factors contributing to an increased risk of heart failure. Every 10 year increase in age was associated with a 45% increased risk. Greater socioeconomic deprivation was associated with a 27% increased risk. Several co-morbid health conditions increased risk, with diabetes increasing risk by 44%, COPD increasing risk by 28% and hypertension increasing risk by 16%. Increased risk of later incidence of heart failure was also associated with atrial fibrillation (63% increased risk), peripheral artery disease (38% increased risk) and ST elevation myocardial infarction at presentation (21% increased risk).

The authors concluded by saying that identifying prognostic factors in heart attack patients could reduce heart failure incidence by targeting treatments to reduce risk.
