Résumé
The relationship between long-term outcome in patients with lower extremity artery disease (LEAD) and left ventricular (LV) diastolic dysfunction has not been systematically studied. The aim of this study was to assess the impact of LV diastolic dysfunction on the long-term outcome in patients with LEAD. Two hundred LEAD patients (male 66 %, mean age 76±9 years) with preserved LV systolic function assessed by echocardiography (ejection fraction ≥50 %) were enrolled from a single center database between January 2013 and May 2015. We divided the patients into two groups on the basis of LV diastolic dysfunction, which was diagnosed based on the American Society of Echocardiography/European Association of Cardiovascular Imaging guidelines. The 3-year cumulative incidence of the primary endpoint was compared between LEAD patients with LV diastolic dysfunction and those without. The primary endpoint was a composite of major adverse cardiac and cerebrovascular events (MACCE: death, hospitalization for heart failure, myocardial infarction, and stroke). Multivariate analysis was performed to determine whether LV diastolic dysfunction was independently associated with the MACCE. LV diastolic dysfunction was identified in 31 % of LEAD patients. The mean observation period was 32±21 months. The 3-year cumulative incidence of MACCE occurred more frequently in patients with LV diastolic dysfunction than those without (35 % vs 23 %, p=0.01). In multivariate analysis, LV diastolic dysfunction (HR=1.96, 95 % CI 1.09-3.55, p=0.03) and critical limb ischemia (HR=2.52, 95 % CI 1.24-5.10, p=0.01) were an independent predictor for MACCE. LV diastolic dysfunction increased the risk for MACCE in patients with LEAD.

BACKGROUND
The relationship between long-term outcome in patients with lower extremity artery disease (LEAD) and left ventricular (LV) diastolic dysfunction has not been systematically studied. The aim of this study was to assess the impact of LV diastolic dysfunction on the long-term outcome in patients with LEAD.
METHODS
Two hundred LEAD patients (male 66 %, mean age 76±9 years) with preserved LV systolic function assessed by echocardiography (ejection fraction ≥50 %) were enrolled from a single center database between January 2013 and May 2015. We divided the patients into two groups on the basis of LV diastolic dysfunction, which was diagnosed based on the American Society of Echocardiography/European Association of Cardiovascular Imaging guidelines. The 3-year cumulative incidence of the primary endpoint was compared between LEAD patients with LV diastolic dysfunction and those without. The primary endpoint was a composite of major adverse cardiac and cerebrovascular events (MACCE: death, hospitalization for heart failure, myocardial infarction, and stroke). Multivariate analysis was performed to determine whether LV diastolic dysfunction was independently associated with the MACCE.
RESULTS
LV diastolic dysfunction was identified in 31 % of LEAD patients. The mean observation period was 32±21 months. The 3-year cumulative incidence of MACCE occurred more frequently in patients with LV diastolic dysfunction than those without (35 % vs 23 %, p=0.01). In multivariate analysis, LV diastolic dysfunction (HR=1.96, 95 % CI 1.09-3.55, p=0.03) and critical limb ischemia (HR=2.52, 95 % CI 1.24-5.10, p=0.01) were an independent predictor for MACCE.
CONCLUSION
LV diastolic dysfunction increased the risk for MACCE in patients with LEAD.
