摘要
Background and aims: Previous data show contradicting results regarding relevance of obesity on outcome in peripheral arterial disease (PAD). Thus, this study aims to evaluate the predictive power of obesity as measured by established and novel obesity indices (waist circumference WC, waist-hip ratio WHR, body-mass index BMI, body adiposity index BAI, visceral adiposity index VAI, weight-adjusted waist index WWI) in a PAD cohort. Methods and results: In 367 patients with diagnosed PAD anthropometric parameters were assessed at study inclusion in an observational study. Mortality data was retrieved from the central death registry after five years. Outcome analyses were performed by multivariable Cox-regression models. 57 PAD patients (15.5%) died during the follow-up, of those 36 were categorized as cardiovascular origin. Patients from the all-cause mortality group were older, more often diabetics with a worse glucose control and had worse renal function. Obesity indices were not significantly different between the event and control group. None of the evaluated risk factors predicted cardiovascular or all-cause death after multivariable adjustment for age, gender, LDL-C, serum creatinine, systolic blood pressure, CRP, smoking habits, diabetes status and previous history of peripheral revascularisation (all-cause WC 1.007 (0.983-1.031), WHR 1.772 (0.106 -29.595), BMI 1.006 (0.939-1.078), BAI 1.002 (0.945-1.063), VAI 1.019 (0.895-1.161), WWI 1.085 (0.831-1.416); cv-death WC 1.007 (0.978-1.036), WHR 0.382 (0.006-25.338), BMI 1.004 (0.918-1.098), BAI 1.034 (0.959-1.116), VAI 1.036 (0.885-1.213), WWI 1.061 (0.782-1.441)). Conclusion: Obesity as risk marker estimated by indices both for general and visceral adiposity, does not predict mortality in a secondary prevention cohort of PAD patients.
