To study the coronary artery disease (CAD) pattern by angiogram using Gensini score in cities, urban and rural populations.

A cross-sectional study of all patients with CAD coming to Bhagawan Mahaveer Jain Heart Centre, Bangalore, or its peripheral centres from city, urban and rural areas presenting with known or suspected CAD with chest pain suggestive of CAD and various investigations suggestive of CAD were screened. Patients with evidence of CAD on coronary angiogram were included in the study

In total, there were 400 patients with evidence of CAD on coronary angiogram. Among them, the number of patients from city areas was 197, from urban areas was 102 and from rural areas was 101. Patients were divided into three groups as per their Gensini score: those with 50 score, 51–150 score and > 150 score. Majority of the patients belonged to the 50 score group, with 129 (65.5%) from city, 67 (65.7%) from urban and 81 (80.2%) from rural areas. In the 51–150 Gensini-score group, 67 (34.0%) were from city, 33 (32.4%) from urban and 20 (19.8%) from rura areas. In the > 150 Gensini-score group, 1 (0.5%) was from city, 2 (2.0%) from urban and none from rural areas, with significant difference between the groups (p = 0.041).

Gensini score was higher in city population than in rural population, indicating increased burden of coronary lesions in the former
