As in any other CAD study, the male population was predominant. Among the conventional risk factors, the most common one was dyslipidemia (Table 2). Most of the patients in each group were asymptomatic and were leading active life style. Significant number of patients in each group 61.6% and 56.2% had undergone percutaneous revascularization while more than 20% were post-coronary artery bypass graft patients. Even though the two groups appear very much heterogeneous, statistically they are comparable.
