Survey of Assessment and MAnagement of CoRonary Heart Disease PaTients (SMART) in India.

OBJECTIVE

Survey of Assessment and MAnagement of CoRonary Heart Disease PaTients was undertaken to describe profile and management pattern of adult Acute Coronary Syndrome (ACS) patients from presentation till discharge, in private tertiary care Indian hospitals.

MATERIALS AND

METHODS

This was an observational, prospective study. Based on standard criteria, patients were diagnosed to have ST-segment elevation myocardial infarction (STEMI), non-ST-segment elevation myocardial infarction (NSTEMI) or unstable angina (UA). For patients surviving till hospital discharge, demographic characteristics, medical history, time to hospital presentation, investigations, vascular interventions and medical management during the hospital stay were recorded.

RESULTS

In total, 1340 patients with definitive ACS diagnosis and surviving their hospital stay were enrolled. Mean patient age was 58.7 years, 75% were males and 36.9% were diagnosed with STEMI, 8.9% with NSTEMI and 54.2% with UA. 41.9%, 35% and 18.4% patients reached hospital within 6 hours for STEMI, NSTEMI and UA respectively. Pre-existing hypertension and diabetes were observed less frequently in patients with STEMI (54.8%, 31.9%) than in NSTEMI (70.8%, 45.8%) or UA (64.2%, 41.5%). Aspirin, clopidogrel, nitrates, β-Blockers, angiotensin converting enzyme inhibitors and statins were used more frequently in NSTEMI than in STEMI or UA patients. Percutaneous trans-coronary angioplasty was performed more commonly in STEMI (64.2%) than in NSTEMI (41.7%) or UA (41.2%).

CONCLUSIONS

UA is the commonest and NSTEMI is the least common type of ACS observed in our study. We observed important differences in patient profile, time to hospital presentation, in-hospital acute pharmacological management and vascular interventions performed between the three different types of ACS.
