Prospective cohort study of the temporal profile of QT dispersion in acute myocardial infarction
Abstract
Coronary artery disease has become the prime killer of man today. The absolute number of patients who will have MI is expected to increase in the future. Accordingly, sudden cardiac death after MI will continue to be a significant clinical problem. Identification of MI patients with preserved LVEF >40% at risk of dying suddenly, however, is an unresolved clinical challenge (1).
The mortality rate in acute myocardial infarction is approximately 30% within first month. It is all the more important as 50% of these deaths are sudden cardiac deaths and affects people in most productive period of life(2).
