Клінічна характеристика пацієнтів похилого віку з ураженням основного стовбура лівої коронарної артерії

​The​ ​aim – to analyze the clinical features of elderly patients with left main coronary artery disease (CAD).Materials and methods. This prospective cohort study included 124 patients with left main CAD aged 60 to 75 years (elderly age group) and 100 control patients aged 44 to 60 who underwent coronary angiography between September 2021 and July 2024. Demographic data, history of coronary artery disease and associated diseases, laboratory test results, results of echocardiography and coronary angiography were collected and analyzed. Results. Elderly patients were characterized by a significantly higher (p = 0.030) frequency of myocardial infarction, as well as higher (p = 0.035) frequency of previous percutaneous coronary interventions compared to middle-aged patients. Elderly patients also had a significantly higher functional class according to NYHA compared to middle-aged patients (p = 0.0005), significantly higher rate of arterial hypertension (p = 0.012), diabetes mellitus (p = 0.033), cerebrovascular disease (p = 0.009), chronic kidney disease (p = 0.011) and anemia (p = 0.044), compared to middle-aged patients. Moreover, elderly patients were characterized by significantly higher creatinine, LDL and glucose levels.Conclusions. Elderly patients with left main CAD were characterized by a more severe course of the disease, more severe coronary lesions, and a higher frequency of concomitant cardiac and non-cardiac diseases compared to middle-aged patients.
