Abstract   Aims  Lower extremity arterial disease (LEAD) and left ventricular diastolic dysfunction (LVDD) share many risk factors, but the characteristics of LVDD and its association with prognosis in patients with LEAD have not been fully examined.    Methods and results  We investigated the impact of LVDD on the clinical outcomes in LEAD patients. LVDD was classified according to the newest suggested classification by the American Society of Echocardiography. Survival analysis for mortality (primary endpoint) and major adverse cardiac events (MACE; secondary endpoint) was calculated with all clinical variables and adjusted by multivariate Cox regression. We consecutively enrolled 221 controls and 464 LEAD patients from outpatient clinics and hospitals. The prevalence of LVDD was proportional to the severity of LEAD defined by the Rutherford class. The difference of LVDD severity is significant when compared with the control and LEAD patients or LEAD patients who underwent endovascular therapy (EVT), and it is also proportional to the LEAD severity. The grade of LVDD was a significant factor in predicting MACE and mortality in LEAD patients after multivariate Cox regression analysis [hazard ratio (HR) = 2.11, 95% CI = 1.47–2.83,  P  = 0.026; HR = 1.47, 95% CI = 1.02–2.02,  P  = 0.041]. This impact remained significant in LEAD patients who underwent EVT.    Conclusions  The degree of LVDD may predict MACE and mortality in LEAD patients. Whether early identification of LVDD in LEAD patients is helpful warrants further large‐scale prospective randomized studies.
