Coronary artery disease (CAD) is a major cardiovascular disease (CVD) that affects a large population globally. This study aimed at determining coronary arterial lesions (CAL), particularly in terms of age, gender, coronary artery/arteries involved, number of lesions, and dominant coronary artery in the Kingdom of Saudi Arabia (KSA).
A cross-sectional study was conducted at the King Khalid Hospital and Prince Sultan Centre for Health Care in Al-Kharj between January 2017 and March 2018. The patients with CAD lesion/s, fulfilling the inclusion criteria, were recruited from the cardiovascular medicine unit. Demographic information and the location and extent of their CAD lesions were extracted and documented in electronic case report form (eCRF). SPSS 22.0 was used for statistical analysis, and p value ≤ 0.05 was considered as significant.
Of the 262 patients, male and female preponderance was 74.8% and 25.2%, respectively. The majority of the patients were adults above the age of 50 (72%). About half of all patients were active smokers (53%). Diabetes, hypertension, and hyperlipidaemia were recorded in 63%, 53.7% and 25% respectively. The incidence of cardiovascular lesions was documented after coronary angiography; left circumflex artery lesions had the highest incidence (85.3%), followed by left anterior descending artery lesions (82.4%) and right circumflex artery lesions (74.3%). Left main coronary artery lesions had the lowest incidence (10.3%). Most patients (59.6%) had three concomitant lesions, whereas a minority of patients had two (22.8%) and one lesion (17.7%).
The pattern of CALs is different among the Saudi population as compared to other countries.
冠状动脉疾病（CAD）是一种主要的心血管疾病（CVD），全球有大量人口受其影响。本研究旨在确定沙特阿拉伯王国（KSA）的冠状动脉病变（CAL），特别是在年龄、性别、受累冠状动脉、病变数量和优势冠状动脉方面。
2017年1月至2018年3月在哈立德国王医院和位于哈吉尔的苏丹王子医疗中心进行了一项横断面研究。符合纳入标准的CAD病变患者从心血管内科招募。提取人口统计学信息以及他们CAD病变的位置和范围，并记录在电子病例报告表（eCRF）中。使用SPSS 22.0进行统计分析，p值≤0.05被认为具有统计学意义。
在262例患者中，男性和女性的占比分别为74.8%和25.2%。大多数患者为50岁以上的成年人（72%）。所有患者中约一半为现吸烟者（53%）。糖尿病、高血压和高脂血症的记录率分别为63%、53.7%和25%。冠状动脉造影后记录了心血管病变的发生率；左旋支动脉病变的发生率最高（85.3%），其次是左前降支动脉病变（82.4%）和右回旋支动脉病变（74.3%）。左主干冠状动脉病变的发生率最低（10.3%）。大多数患者（59.6%）有三种合并病变，而少数患者有两种（22.8%）和一种病变（17.7%）。
与其他国家相比，沙特人群中CAL的模式有所不同。
