Severity and distribution of coronary artery disease in lebanese patients undergoing coronary angiography: Impact of gender and age on angiographic characteristics, a cross-sectional study.

The study included 212 Lebanese patients with angiographically confirmed CAD with a mean age of 60.6 years and slight male predominance.

• Total sample size was 212 patients with CAD
• 51.4% of patients were male
• Mean age was 60.6 years
• Patients were enrolled between January 2021 and February 2022
• This was described as the first study in Lebanon to evaluate gender- and age-related differences in angiographic patterns and clinical characteristics of CAD

Male patients more frequently had prior angina, myocardial infarction, and coronary revascularization compared to female patients.

• Prior history of angina, myocardial infarction, and coronary revascularization were all more common in male patients
• These differences were observed in a multicenter, cross-sectional study design
• Data were obtained through patient interviews and comprehensive review of medical records

Male patients exhibited more severe coronary lesions, particularly involving the left anterior descending artery.

• Males showed more severe coronary lesions compared to females
• The left anterior descending artery was particularly more involved in male patients
• Among patients with multivessel disease (MVD), males had a greater extent of coronary involvement

Younger patients (≤55 years) more often reported a family history of CAD compared to older patients.

• Patients were stratified into younger (≤55 years) and older (>55 years) age groups
• Family history of CAD was more frequently reported among younger patients
• This suggests a stronger hereditary component in early-onset CAD in this Lebanese population

Older patients (>55 years) had a higher prevalence of cardiovascular comorbidities, prior ischemic events, coronary interventions, heart failure, and reduced left ventricular ejection fraction.

• Older patients (>55 years) demonstrated greater comorbidity burden compared to younger patients
• Prior ischemic events and coronary interventions were more common in the older age group
• Heart failure and reduced left ventricular ejection fraction were more prevalent in older patients
• Echocardiographic assessment of left ventricular systolic function was included in data collection
