摘要

AIM: To investigate the relationship between coronary artery calcium (CAC) score and left ventricular global longitudinal strain (LV GLS) in patients with arterial hypertension who had a negative treadmill exercise stress test but mild to intermediate coronary stenosis on coronary computed tomography angiography (CCTA). METHODS: A total of 53 hypertensive patients (mean age 54.8 ± 4.8 years; 50.9% male) with 30-50% coronary stenosis on CCTA were included. Patients with diabetes, malignancy, or established coronary/peripheral artery disease were excluded. CAC score, left ventricular ejection fraction (LVEF, Simpson's method), and LV GLS (speckle-tracking echocardiography) were measured. Groups were stratified by GLS (< 18.5% vs. ≥ 18.5%) and LVEF (< 60% vs. ≥ 60%), and CAC score differences were assessed using the Mann-Whitney U test. RESULTS: The median CAC score was 27 (IQR 16-44.5), median LVEF 60% (IQR 58-63%), and mean GLS 19.37 ± 0.89%. No overall association was found between CAC score and LV function by LVEF or GLS. In patients with left anterior descending (LAD) stenosis (30-50%), reduced LV function was linked to significantly higher CAC score. Median CAC score was higher in patients with GLS ≤ 18.5% (157 vs. 44.5; p = 0.019) and LVEF <60% (157 vs. 44.5; p = 0.019). No significant associations were found in right coronary artery (RCA), circumflex artery (Cx), or three-vessel stenosis subgroups. CONCLUSION: Higher CAC score in hypertensive patients with mild LAD stenosis and negative stress testing identify those at risk of subclinical LV dysfunction.
