Ankle blood pressure as a predictor of total and cardiovascular mortality

Table 3 Hazard Ratios (HR, 95% Confidence Interval (CI) of Cardiovascular and All-Cause Deaths in Different Levels of Ankle Blood Pressure (ABP).¹

	Model 1			Model 2
Ankle Blood Pressure Category (n)	HR	95% CI	p	HR	95% CI	p
Cardiovascular death
100–150 mmHg (n = 1214)	1	(reference)		1	(reference)
151–174 mmHg (n = 1082)	1.54	0.85 – 2.79	0.2	1.52	0.83 – 2.78	0.2
175–200 mmHg (n = 1086)	1.71	0.97 – 3.02	0.06	1.73	0.97 – 3.07	0.06
201–300 mmHg (n = 355)	1.98	1.03 – 3.84	0.04	1.77	0.91 – 3.45	0.1
Abnormal (< 0.97) ABI (n = 121)	2.38	1.10 – 5.17	0.03	1.53	0.68 – 3.4	0.3
All-cause death
100–150 mmHg (n = 1214)	1	(reference)		1	(reference)
151–174 mmHg (n = 1082)	1.30	0.95 – 1.79	0.1	1.30	0.94 – 1.79	0.2
175–200 mmHg (n = 1086)	1.44	1.06 – 1.95	0.02	1.47	1.08 – 2.00	0.02
201–300 mmHg (n = 335)	1.70	1.18 – 2.43	0.003	1.53	1.06 – 2.21	0.02
Abnormal (0.97) ABI (n = 121)	2.20	1.43 – 3.40	< 0.0001	1.49	1.00 – 2.33	0.02

Model 1: adjusted for age and sex
Model 2: adjusted for age, sex, BMI, smoking, early parental cardiovascular disease, exercise capacity measured in metabolic equivalents, self-reported elevated cholesterol and abnormal blood glucose
Please see Table 1 and the Methods-section for the explanation for the blood pressure groups
¹ Persons with low ABI separated as their own group
