Analysis of Characteristics of Coronary Artery Stenosis Based on the Comorbidities in Coronary Heart Disease Patients Undergoing Coronary Angiography

Abstract

Background: Comorbid diseases are a risk factor for atherosclerosis in coronary heart disease (CHD). Atherosclerosis causes the narrowing of the coronary arteries so that the heart muscles lack blood supply. Diagnostic coronary angiography is an invasive medical examination performed to determine the presence of coronary artery stenosis and to show the location and the number of coronary artery stenosis. Objective: This study aimed to analyze the characteristics of coronary artery stenosis based on comorbidities of patients with CHD undergoing coronary angiography. Methods: This analytical study was conducted using a cross-sectional design of 105 patients with CHD undergoing coronary angiographyat the catheterization laboratory at Bahteramas Hospital, Southeast Sulawesi, from January 1 to December 31, 2021.Statistical testing used Chi-squaretests with 95% confidence interval and significance set as p<0.05. Results: Most of the respondents were over 45 years old as many as 87 (82.9%), and most are male as many as 72 (68.6%). The category of the highest number of stenosis was less than two stenosis, namely 70 patients (66.7%) with the most common location as the Left Anterior Descending. The comorbidities category included a history of dyslipidemia in 41 people (39.0%), history of diabetes mellitus (DM) in 28 people (26.7%), and history of hypertension in 75 people (71.4%).The bivariate analysis showed a history of DM was associated with coronary artery stenosis (p-value = 0.007) with an Odds Ratio of 3.111. Conclusions: Patients with DM have 3.111 times greater possibility of developing stenosis of the coronary arteries.WC:246
