Abstract: | Arterial stiffening is a hallmark of the aging process and atherosclerosis, including peripheral arterial disease (PAD). We investigated the associations between carotid‐femoral pulse wave velocity (c‐fPWV), augmentation index corrected for heart rate (Aix@HR75), ankle brachial index (ABI), and subendocardial viability ratio (SEVR), an indicator of cardiac perfusion. The c‐fPWV, Aix@HR75, and SEVR was estimated using applanation tonometry. The ankle systolic pressure measurements for the calculation of the ABI were obtained using an 8‐mHz Doppler probe. The study group included 555 subjects, mean age 63 ± 11 years (248 PAD (ABI < 1.0), and 307 non‐PAD (ABI ≥ 1.0 ≤ 1.3). After the stepwise selection process in both PAD and non‐PAD patients SEVR was not related to c‐fPWV and ABI (P = .154; P = .156) and (P = .101; P = .402), respectively. In PAD patients, SEVR was negatively related to Aix@HR75 (P < .0001) and aortic PP (P = .0005). In conclusion, arterial stiffness is associated with non‐invasive indices of myocardial perfusion in PAD patients, suggesting a potential pathophysiological link for increased cardiovascular events. |
