ABSTRACT

Most common causes of death and morbidity worldwide, particularly in developed countries, are coronary heart diseases. This study used coronary angiography to identify the dominant coronary artery in the Saudi population and assess the arterial supply to the atrioventricular node and bundle in relation to the degree of coronary artery stenosis. Retrospective research was done on patients who visited the King Fahad Cardiac Center, Riyadh between January, 2022 and December, 2022. The records of 310 patients, aged 18 years or older, of both sexes, whose coronary artery angiography revealed disease in coronary arteries, were included as a sample in the study. The results revealed that the right coronary artery predominated in both male and female Saudi patients (56.1%) and that both the right coronary artery and anterior descending artery were equally susceptible to stenosis. There was no connection between sex and the stenosis site. The results also revealed a weak relationship between the dominant coronary artery and the degree of right coronary artery stenosis and anterior descending artery stenosis reduction.
