Abstract
Background Coronary artery disease, as well as other cardiovascular diseases, poses a significant health burden globally. Understanding the relationship between clinical variables and coronary artery disease is crucial for effective management. This study explores the link between carotid intima-media thickness and different risk factors in the Indian population. Aims and objectives The primary objective of this study is to investigate the correlation between coronary artery disease and carotid intima-media thickness in a cohort of Indian individuals. Secondary objectives include analyzing the impact of demographic factors, lifestyle choices, and biomarkers on coronary artery disease risk. Methodology This study adopts an analytic, prospective case-control design spanning 18 months from July 2022 to December 2023. The research is conducted in a hospital setting, utilizing data from patients undergoing coronary angiography. The case group comprises 42 patients diagnosed with coronary artery disease, while the control group consists of 18 age-matched individuals without coronary artery disease. Demographic details, lifestyle factors, and biomarker levels are assessed. Statistical analyses involve Fisher's exact tests, chi-square tests, ANOVA, and independent sample t-tests. Primary outcome measures include the association between carotid intima-media thickness and coronary artery disease, as well as the impact of demographic and lifestyle factors on coronary artery disease risk. Secondary outcome measures involve the predictive capability of carotid intima-media thickness through receiver operating characteristic (ROC) curve analysis. Results Significant findings include a notable association between gender and coronary artery disease, with a statistically significant relationship observed for smoking, alcohol consumption, and hypertension. Biomarkers such as high-sensitivity C-reactive protein (hs-CRP) and carotid intima-media thickness exhibit highly significant differences in coronary artery disease patients compared to controls. Conclusions This study underscores the importance of carotid intima-media thickness as a potential predictor for coronary artery disease in the Indian population. Gender, lifestyle choices, and certain biomarkers significantly influence coronary artery disease risk. These findings contribute to a nuanced understanding of coronary artery disease etiology and risk stratification. This study sheds light on the intricate interplay of clinical factors influencing coronary artery disease in the Indian population, paving the way for enhanced risk assessment and preventative strategies.
