Ejection fraction at the first attack of myocardial infarction and postinfarction survival in south Indian population.

ABSTRACT

Ischemic heart disease is estimated to be the most important cause of mortality by the end of 2020 world wide despite sufficient improvement in health care. It has several modifiable and few non modifiable prognostic variables. Therefore, we analyzed the data of all patients admitted for the first time for acute myocardial infarction (MI) and evaluated the long term modifiable prognostic variables retrospectively. We did not find any difference in the age, blood pressure, hematological and several biochemical parameters between patients who survived and those who expired in 4 years of follow up. Our study revealed that in the expired group patients, the mean admission heart rate, ejection fraction, serum urea and creatinine levels were higher and bicarbonate level was lower compared to survived group patients at the first attack of MI. Also, despite the less incidence of myocardial infarction in females, the percentage of cardiac death was higher in female MI patients. We suggest from our retrospective analysis that MI patients with higher heart rate, altered renal function and metabolic acidosis should be rigorously followed up and special counseling should be provided to old age female patients for better prognosis and survival.
