Abstract

Coronary heart disease is a cardiovascular disease caused by the blockage of the coronary arteries due to plaque buildup. According to the World Health Organization (WHO) in 2021, heart disease is the leading cause of death from non-communicable diseases, accounting for 43,6% of total deaths from non communicable diseases worldwide. In 2024, Mitra Sejati General Hospital recorded 253 cases of CHD. This study aims to identify risk factors associated with the occurrence of coronary heart disease in outpatients at Mitra Sejati General Hospital in 2025. This is a quantitative study using a cross-sectional design. The sample size in this study was 120 people, selected using accidental sampling. Data were collected through interviews and medical records. The univariate analysis results show that most respondents were aged 55-74 years (64,1%), male (53,3%), Batak ethnicity (57,5%), high school/equivalent education (50,8%), unemployed (52,5%), no family history of coronary heart disease (78,3%), no hypertension (63,3%), normal cholesterol levels (75%), not obese (52,5%), non-smokers (74,2%), and non-alcohol consumers (94,2%). Bivariate analysis using the Chi-square test found a significant relationship between age (p<0,05), gender (p<0,05), occupation (<0,05), family history (p<0,05), hypertension (p<0,05), cholesterol levels (p<0,05), obesity (p<0,05), and smoking habits (p<0,05). There is no relationship between ethnicity (p>0,05), education (p>0,05), and alcohol consumption (p>0,05) with the incidence of coronary heart disease. The recommendation to the public is to adopt a healthy lifestyle, including quitting smoking, maintaining a healthy weight, and controlling blood pressure and cholesterol levels.
