ABSTRACT
Objective: To determine the frequency of coronary artery disease in suspected patients with zero calcium score on coronary CT angiography.
Study Design: Cross-sectional study
Place and Duration of Study: This study was conducted at the Department of Cardiology, Ch. Pervaiz Elahi Institute of Cardiology, Multan 1-Aug-2017 to 31-Jan-2018.
Materials and Methods: A total number of 86 patients having age 18 to 65 years, with suspicion of coronary artery disease and having zero calcium score on CT angiography were included in this study. The data was analyzed through statistical analysis software (SPSS version 21.0). Qualitative variables e.g. gender, diabetes and presence of CAD was presented as frequency and percentage. Stratification of confounder variables was done. Post-stratification Chi-square test was applied.
Results: Mean age of study patients was 49.43+8.16 years. There were 71 (82.56%) male patients and 15 (17.44%) female patients. There were 37 (43.02%) diabetic patients. Coronary artery disease was diagnosed in 5 (5.81%) patients. while remaining 81 (94.19%) patients were having normal coronary arteries. There was no effect of age and gender on frequency of CAD. In diabetic patients, CAD was diagnosed in 4 patients and in only 1 patient without diabetes mellitus. Frequency of CAD was high in diabetics but statistically insignificant.
Conclusion: In our study, frequency of coronary artery disease in patients with zero calcium score on CT angiography was 5.81%.
Key Words: Coronary artery disease, coronary artery calcium score, CT angiography.
