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@ HR 75), ankle brachial index ( ABI ), and subendocardial viability ratio ( SEVR ), an indicator of cardiac perfusion. The c‐ fPWV , Aix@ HR 75, and SEVR was estimated using applanation tonometry. The ankle systolic pressure measurements for the calculation of the ABI were obtained using an 8‐ mH z 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@ HR 75 ( 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.
