Association of CHADS₂ and CHA₂DS₂-VASc Scores with Left Atrial Thrombus with Nonvalvular Atrial Fibrillation: A Single Center Based Retrospective Study in a Cohort of 2695 Chinese Subjects

Table 2

Presence of LAT by CHADS₂ or CHA₂DS₂-VAS scores.

Risk category	Total number	LAT, (%)	values (χ^2 test)
CHADS2 score
0	1234	27 (2.2)	0.07
1	971	35 (3.6)
2+	490	19 (3.9)
CHA2DS2-VASc score
0	728	14 (1.9)	0.12
1	855	27 (3.2)
2+	1112	40 (3.6)

LAT = left atrial thrombus; CHADS₂ = congestive heart failure, hypertension, age ≥ 75 years, diabetes mellitus, and previous stroke/transient ischemic attack [double risk weight]; CHA₂DS₂-VASc = congestive heart failure, hypertension, age ≥ 75 years [doubled risk weight], diabetes mellitus, previous stroke/transient ischemic attack [doubled risk weight], vascular disease, age 65 to 74 years, and sex; TEE = transesophageal echocardiogram.
