Prognosis of Developing Heart Failure Following ST Elevation (STEMI) and Non ST Elevation (NSTEMI) Infarct

Patients with myocardial infarction (MI) and Heart failure (HF) have a poor prognosis. However, there is a paucity of data investigating the difference in the prognosis of patients who developed HF following either ST elevation (STEMI) or non-ST elevation MI (NSTEMI) as evidenced by electrocardiogram (ECG). Aim: To identify the prognosis of patients who develop HF following STEMI and NSTEMI. Method: Case notes of 204 patients who had an MI in 1998 were identified according to the hospital discharge summary by the Hull & East Yorkshire Hospitals Trust Information Department, were used to identify events between 1998 and 2005. Results: 40% had died by the end of 205. 68% of the sample were male (mean age 67 ±12 years). 71% of patients had STEMI and 29% had NSTEMI. The overall mortality was similar in STEMI and NSTEMI (41% vs 32%). However, there was a trend towards higher early mortality in STEMI during index admission (21% vs 11%). 81 patients developed HF following MI during the index admission. These patients had higher early (during first admission), late (during follow-up) and overall mortality rates when compared to those who did not develop heart failure Similar trends were observed in those with STEMI and NSTEMI.
