Gender differences related to the presence of atrial fibrillation in older hypertensive patients

Table 3 Independent predictors of global atrial fibrillation in the total study population and in subgroups according to gender

Variable	Total	Females	Males
	OR (95%CI)	OR (95%CI)	OR (95%CI)
Age, yr	1.1 (1.1-1.1)	1.1 (1.1-1.1)	1.1 (1.03-1.13)
	P < 0.001	P = 0.010	P = 0.003
Alcohol abuse	5.2 (2.1-12.2)	7.0 (0.6-82.9)	4.2 (1.5-11.4)
	P = 0.001	NS	P = 0.005
Heart disease	4.7 (3.0-7.5)	6.1 (3.1-12.4),	3.4 (1.9-6.2)
	P < 0.001	P < 0.001	P < 0.01
GFR, mL/min per m2	0.98 (0.97-0.99)	0.98 (0.96-0.99)	0.99 (0.9-1.0)
	P = 0.027	P = 0.039	NS

	P = NS	P = 0.032	NS

Multivariate analysis: Age, gender, body mass index, physical exercise, alcohol use, time from the onset of hypertension, clinical blood pressure, 24-h ambulatory blood pressure monitoring result, family history of early cardiovascular disease, diabetes, smoking, obesity, dyslipidaemia, abdominal obesity, left ventricular hypertrophy, atherosclerotic plaque, renal damage, coronary disease, heart failure, renal disease, and treatment type. GFR: Glomerular filtration rate; ECG: Electrocardiogram; NS: No significant.
