Correlation Between CHA₂DS₂-VASc Scores and Left Atrial Measurements: A Single-Center Retrospective Study.

Background: Left atrial (LA) and left atrial appendage (LAA) remodeling are critical indicators of adverse cardiovascular outcomes linked to various risk factors. This study aims to investigate the correlation between CHA2DS2-VASc and left atrial measurements in patients with sinus rhythm.

Methodology: The retrospective, single-center study included 250 patients who underwent coronary computed tomography angiography (CCTA) imaging at a state hospital in Turkey. LA dimensions, volumes, LAA types, and LAA orifice area and volume were assessed using CCTA images. Additionally, we evaluated CHA₂DS₂-VASc scores and cardiovascular risk factors.

Results: This present study indicated that patients with low CHA₂DS₂-VASc scores had smaller appendage orifice area (270.69±84.72 vs. 300.97±97.65 mm², p=0.01), LA long diameter (60.73±6.83 vs. 64.53±7.66 mm, p<0.001), LA short diameter (40.32±5.88 vs. 43.02±6.54 mm, p=0.001), and LA volume (101.55±34.14 vs. 114.34±32.58 mm³, p=0.003). There was a significant relationship between patient age and all LA and LAA measurements, including LAA volume (r=0.204, p<0.001), LAA orifice area (r=0.342, p<0.001), LA long diameter (r=0.329, p<0.001), LA short diameter (r=0.257, p<0.001), and LA volume (r=0.231, p<0.001).

Conclusion: Cardiovascular risk factors and CHA₂DS₂-VASc scores are valuable markers for assessing atrial cardiomyopathy and left atrial appendage (LAA) remodeling, and they may aid in predicting stroke risk.
