Abstract

Cardiovascular disease particularly ischemic heart disease has emerged as a leading cause of death. Atherosclerosis in epicardium results in CAD without the restriction of coronary circulation but the other processes that may disrupt the myocardial supply and demand in patients exhibiting angina symptoms or indications may be suspected of having non-obstructive CAD. Objective: To find out the prevalence of non-obstructive CAD in patients enrolled for elective angiography. Methods: A cross-sectional descriptive analysis was done in the Cardiology department in King Edward Medical University and Mayo Hospital, Lahore. The duration of study was for six months from 01-08-2022 to 01-02-2023. After approval from hospital ethical committee, 150 patients were enrolled in the study with informed written consent. Demographics including Name, age, BMI, confounding factors like (diabetes, hypertension, smoking and family history) and address were noted. All selected patients underwent coronary angiography via right femoral artery approach by a consultant cardiologist. Non-obstructive coronary artery disease was assessed as per operational definition. All the information was noted on pre-designed proforma (attached). Results: A total of 150 patients were selected for the study. It showed that out of 150 patients, 2.7% (n=4) fall in age group of 18-40 years and 97.3 % (n=146) were in age group of 41-60 years, average age was 51.94±5.26 years and the BMI was 27.96±6.44 kg/m2. There were 62.7 % (n=94) male and 37.3 % (n=56) females. Frequency of diabetes mellitus was 34.7 % (n=52), hypertension was 24.7 % (n=37), smokers 16.7 % (n=25), family history was 12.7 % (n=19) and frequency of non-obstructive CAD was 27.3 % (n=41). Conclusions: It is to be concluded that a considerable percentage of patients enrolled for elective coronary angiography had non-obstructive CAD.
