• The Prevalence, Clinical Spectrum and the Long Term Outcome of ST-segment Elevation Myocardial Infarction in Young - A Prospective Observational Study

    Abstract

    Introduction

    Incidence of coronary artery disease at the younger age is rising. We studied the prevalence, clinical spectrum and long term outcome of ST-segment elevation myocardial infarction in young.

    Material and methods

    This is a prospective observational study, performed at a tertiary care center from January 2015 to June 2016. Of the total 977 consecutive patients with ST segment elevation myocardial infarction (STEMI), 130 patients aged ≤45 years were included. All patients were followed-up for at least 1-year from the index admission.

    Results

    The overall prevalence of STEMI among younger patients was 12.8%. There was male dominance (96.8%). Smoking (37.6%) was observed to be the most common risk factor for young STEMI, followed by diabetes mellitus (16.8%) and hypertension (16%). Younger patients with acute MI had preponderance to anterior wall (68.8%), single-vessel disease (50%) and left anterior descending artery being the culprit lesion (67.3%). Near normal/normal coronary arteries were observed in 12.9% of cases. The most commonly used management strategy was mechanical revascularisation (43.2%), followed by thrombolysis (28.8%) and medical management (28%). The overall mortality and combined MACCE rates at 1 year were 3.2% and 18.4% respectively. Outcome was better in patients who received mechanical revascularization/thrombolysis than those who received medical management only, with a lower MACCE rates (hazard ratio: 0.36; 95% CI: 0.16–0.8, p = 0.01.

    Conclusion

    The young MI patients are unique in having male dominance, better outcome, more of single-vessel disease with significant number of normal coronaries, better response to mechanical as well as pharmacological revascularization.
