title: Correlating the relationship between interarm systolic blood pressure and cardiovascular disease risk factors.
abstract: Interarm systolic blood pressure difference (IASBPD) can predict cardiovascular disease. To investigate the relationship between IASBPD and cardiovascular disease risk factors, a total of 1426 individuals were studied. Blood pressure was assessed simultaneously and IASBPD was expressed as the absolute difference value (|R-L|). Cardiovascular disease risk factors were compared between the high IASBPD group (IASBPD ≥10 mm Hg) and the normal IASBPD group (IASBPD <10 mm Hg). An increased prevalence of hypertension, body mass index, and systolic and diastolic blood pressure were observed in the high IASBPD group (P<.05), associated with the enhanced mean values of intima-media thickness and maximum intima-media thickness (P<.05). Brachial-ankle pulse wave velocity was increased, while ankle-brachial index was lower in the high IASBPD group (P<.05). Multivariate logistic regression analysis revealed that IASBPD ≥10 mm Hg was positively associated with body mass index (odds ratio, 1.077; P=.002) and systolic blood pressure (odds ratio, 1.032; P<.001), and negatively associated with ankle-brachial index (odds ratio, 0.038; P<.001).
