ANALYSIS OF CHOLESTEROL LEVELS AND DEGREE OF STENOSIS IN PATIENTS WITH CORONARY ARTERY DISEASE AT BW HEART HOSPITAL JAKARTA

Abstract

Coronary Artery Disease (CAD) is the leading cause of death worldwide, with an estimated 17.9 million deaths in 2019 due to cardiovascular diseases (CVDs). One of the major types of CVDs is CAD. Dyslipidemia is one of the risk factors contributing to CAD. This study aims to analyze the relationship between cholesterol levels and the degree of stenosis in CAD patients at BW Heart Hospital. The research method used was descriptive correlational with a cross-sectional design. The target population consisted of 250 individuals, and a purposive sampling technique was used to recruit 84 respondents. Univariate and bivariate analyses were conducted, with the Chi-Square test applied at α = 5%. Results showed that 41 respondents (64.1%) had abnormal LDL cholesterol levels and severe stenosis. The Chi-Square analysis indicated a significant relationship between LDL levels and degree of stenosis with a P-value of 0.004 (p < 0.05), leading to the rejection of H0. The study concludes that LDL cholesterol levels are significantly associated with the degree of stenosis in CAD patients. Education to control CAD risk factors—especially LDL levels—is recommended to prevent worsening stenosis.
