Interarm Difference in Blood Pressure: Reproducibility and Association with Peripheral Vascular Disease

Table 1

Systolic blood pressure levels and ankle brachial indices.

Systolic arm blood pressure, right (mmHg)	143±24
Systolic arm blood pressure, left (mmHg)	142±24^∗
Num. diff. in systolic arm blood pressure (mmHg)	8.3±9.1
Systolic ankle blood pressure, right (mmHg)	139±41
Systolic ankle blood pressure, left (mmHg)	138±41
Ankle brachial index >1.30 (%)	5.0
Ankle brachial index 1.00–1.29 (%)	38.1
Ankle brachial index 0.90–0.99 (%)	8.8
Ankle brachial index 0.40–0.89 (%)	43.7
Ankle brachial index <0.39 (%)	4.4

The table shows systolic blood pressure on both arms and ankles and the numerical difference in systolic blood pressure between the two arms given as mean values ± standard deviations. Percentages of patients were grouped according to their ankle brachial index (ABI). ^∗𝑃=0.015 for the differences in systolic blood pressure between the two arms.
