Insights
Coronary artery lesions in Saudi Arabia show a distinct pattern, with the left circumflex artery most frequently affected. This study highlights unique characteristics of coronary artery disease (CAD) in the Saudi population.
Area of Science:
- Cardiology
- Epidemiology
- Public Health
Background:
- Coronary artery disease (CAD) is a significant global cardiovascular disease (CVD).
- Understanding CAD patterns is crucial for targeted healthcare strategies.
- This study focuses on coronary arterial lesions (CAL) in the Kingdom of Saudi Arabia (KSA).
Purpose of the Study:
- To determine the characteristics of coronary arterial lesions (CAL) in Saudi Arabia.
- To analyze CAL patterns based on age, gender, affected coronary artery, lesion number, and dominance.
- To compare CAL patterns in KSA with international data.
Main Methods:
- A cross-sectional study was conducted from January 2017 to March 2018.
- Data from 262 patients with CAD lesions were collected at King Khalid Hospital and Prince Sultan Centre for Health Care.
- Demographic data and lesion details were analyzed using SPSS, with p ≤ 0.05 considered significant.
Main Results:
- The study included 74.8% males and 25.2% females, with 72% over 50 years old.
- Prevalence of smoking, diabetes, hypertension, and hyperlipidemia were 53%, 63%, 53.7%, and 25%, respectively.
- The left circumflex artery had the highest lesion incidence (85.3%), followed by the left anterior descending (82.4%) and right circumflex (74.3%). Most patients (59.6%) had three lesions.
Conclusions:
- The pattern of coronary arterial lesions (CAL) in the Saudi population differs from that observed in other countries.
- This suggests a need for region-specific approaches to CAD management.
- Further research is warranted to elucidate the unique epidemiological profile of CAD in KSA.
Introduction:
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).
Methods:
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.
Results:
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%).
Conclusion:
The pattern of CALs is different among the Saudi population as compared to other countries.
