Objectives
To examine the prevalence of peripheral artery disease (PAD) and the relationship between PAD and cardiovascular (CV) outcomes in subjects with left ventricular systolic dysfunction, heart failure or both after acute myocardial infarction (MI).Background
PAD is associated with poorer prognosis in patients with stable and unstable coronary heart disease but whether PAD is associated with worse outcomes following substantial acute MI is unknown.Methods
Univariate and multivariate Cox proportional hazards modelling was used to compare clinical outcomes in an individual-patient meta-analysis of 4 trials (CAPRICORN, EPHESUS, OPTIMAAL and VALIANT).Results
Of the 28,771 patients randomized, 2357 (8.2%) had PAD. These patients were older and had more co-morbidity and were less likely to be prescribed aspirin or a beta-blocker compared to patients without PAD. Over a mean follow-up of 2.7 years, 5121 (17.8%) patients died and 15,055 (52.3%) experienced CV death or hospitalization. PAD was an independent predictor of all individual and composite CV outcomes examined (including heart failure), with the exception of stroke. In patients with PAD (compared to those without PAD), the adjusted hazard ratio (HR) for all-cause mortality was 1.25 (95% CI 1.15–1.37; p < 0.001) and the HR for CV death, non-fatal MI, non-fatal stroke or heart failure hospitalization was 1.24 (1.16–1.33; p < 0.001).Conclusions
PAD is common and is an independent predictor of worse outcomes in patients already at high risk after MI because of left ventricular systolic dysfunction, heart failure or both. These patients represent an important group for intensive application of secondary preventive therapies. 相似文献2.

The American Heart Association meeting reported the results of several clinical trials of particular interest to those who care for patients with heart failure. Omega-3 fatty acids were associated with a trend to increased recurrence of ventricular arrhythmias but not mortality in patients with an implantable debrillator. The ACTIV in CHF study provides more evidence of a therapeutic role for arginine vasopressin antagonists in the treatment of heart failure. The VALIANT study provides further evidence to suggest that a combination of angiotensin receptor antagonist and ACE inhibitor does not reduce mortality but may reduce morbidity in post-MI patients with heart failure or major LV systolic dysfunction. A study of autologous bone marrow cell transplantation into myocardial scar give gave encouraging results. SPORTIF V showed ximelagation to be as effective as warfarin but with improved safety. ORBIT and PAD showed public access defibrillators saved lives but questioned their cost effectiveness. DEFINITE supported a role for ICDs in patients with non-ischemic cardiomyopathy, although cost-effectiveness remains in doubt. 相似文献
