Correlating the relationship between interarm systolic blood pressure and cardiovascular disease risk factors

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).
