ASSESSMENT OF ANTHROPOMETRIC CHARACTERISTICS IN PATIENTS WITH CORONARY ARTERY DISEASE IN KAZAKHSTAN: DATA FROM A PROSPECTIVE CROSS-SECTIONAL STUDY, SINGLE-CENTER EXPERIENCE

Abstract

Objective: Coronary artery disease (CAD) remains one of the leading causes of mortality and disability worldwide. In
patients with CAD, the lumen of the coronary arteries gradually narrows due to atherosclerosis, leading to an imbalance
between myocardial oxygen supply and demand. Non-invasive methods such as scintigraphy and positron emission
tomography (PET) are widely used for the diagnosis of CAD. Invasive coronary angiography (ICA) has long been considered
the "gold standard" for diagnosing CAD. However, studies have shown that the degree of stenosis determined by ICA does
not always correlate with the functional significance of the lesion. The aim of our study was to investigate the correlations
between the volume, length, and diameter of coronary arteries, myocardial mass (MM), and anthropometric indicators such
as height, weight, body mass index, body surface area, age, and sex.
Methods: We analyzed 654 medical records of patients who underwent inpatient treatment at the Pavlodar Regional
Cardiology Center from November 2024 to January 2025. The patients, aged 18 years and older, were hospitalized with
coronary artery pathology, received conservative treatment, and underwent diagnostic coronary angiography (D-CAG).
Results: Our study revealed a significant positive correlation between the volume of coronary arteries and myocardial
mass, myocardial mass and patient weight, patient height and the length of coronary arteries (p < 0.05). However, no
association was found between the volume of coronary arteries, their diameter, and other anthropometric indicators (body
mass index, body surface area) (p > 0.05).
Conclusion: Thus, our study demonstrates that the dimensions of coronary arteries are closely related to the
anthropometric characteristics of the patient.
