Sex
Male, n (%)	312 (99.05%)	294 (98.99%)	18 (100%)	1.00
Female, n (%)	3 (0.95%)	3 (1.01%)	0 (0%)	1.00
Concomitant disease
Hypertension, n (%)	192 (60.95%)	179 (60.27%)	13 (72.22%)	0.31
Diabetes, n (%)	85 (26.98%)	79 (26.60%)	6 (33.33%)	0.53
CHF*, n (%)	99 (31.43%)	83 (27.95%)	16 (88.89%)	0.00
Stroke/TIA, n (%)	38 (12.06%)	35 (11.78%)	3 (16.67%)	0.88

Notes:

* Continuity correction Chi-square test, P < 0.05. The P value represents a comparison of the sinus rhythm (SR) and atrial fibrillation (AF) groups.

Abbreviations: CHF, chronic heart failure; CAD, coronary heart disease; TIA, transient ischemic attack.

Weight, kg (SD)	70.82 (9.0)	70.78 (9.10)	71.44 (7.58)	0.72

Pulse rate, bpm (SD)	69.83 (9.62)	70.01 (9. 73)	66.83 (7.25)	0.09
Heart rate, bpm (SD)	70.12 (9.74)	70.01 (9. 73)	71.89 (10.08)	0.45
SBP, mmHg (SD)	131.03 (17.31)	131.32 (16.90)	126.33 (23.23)	0.38
DBP*, mmHg (SD)	70.30 (10.83)	71.08 (10.54)	57.33 (6.87)	0.00

Notes:

* t-test, P < 0.05. The P value represents a comparison of the sinus rhythm (SR) and atrial fibrillation (AF) groups.

Abbreviations: BMI, body mass index; SBP, systolic blood pressure; DBP, diastolic blood pressure.

Table 3 The number of vessels with coronary disease in elderly patients with chest distress

	CAD in AF (n = 14)	CAD in SR (n = 275)	χ^2	P value
Single-vessel coronary disease (n, %)	4 (28.57%)	77 (28.0%)	0.00	0.96
Double-vessel coronary disease (n, %)	2 (14.29%)	57 (20.73%)	0.34	0.56
Multivessel coronary disease (n, %)	8 (57.14%)	141 (51.27%)	0.18	0.67

Abbreviations: CAD, coronary artery disease; SR, sinus rhythm; AF, atrial fibrillation.

	AF (n = 18)	SR (n = 297)	χ^2	P value
≤50% (n, %)	4 (22.22%)	31 (10.44%)	2.39	0.12
50%–74% (n, %)	6 (33.33%)	49 (16.50%)	3.34	0.07
≥75%* (n, %)	8 (44.44%)	217 (73.06%)	6.81	0.01

Notes:

* Chi-square test, P< 0.05. The P value represents a comparison of the sinus rhythm (SR) and atrial fibrillation (AF) groups.
