Background: Although there is increasing evidence of the effectiveness of endovascular therapy for complex aortoiliac (AI) occlusive disease, it is not universally applied to TASC D lesions. Methods: A total of 2096 patients, 2601 limbs with AI occlusive disease, were enrolled. The lesions were categorized as TASC D (395) or TASC A-C (2206), and we compared baseline data, procedure, and follow-up result between the 2 groups. Results: The success rate of the procedure was significantly lower in the TASC D group (91.6% vs 99.3%, P < .01), and more procedure complications occurred in the TASC D group (11.1% vs 5.2%, P < .01). The results of a 5-year follow-up revealed no significant difference in primary patency (77.9% vs 77.1%, P = .17) and major adverse cardiovascular and limb events (MACLE; 30.5% vs 33.4%, P = .42) between the 2 groups. A multivariate analysis revealed complications and critical limb ischemia are independent predictors of MACLE in the TASC D group. Conclusion: The success rate of the procedure was lower in the TASC D group. Complications were more frequent in the TASC D group, and they were related to MACLE. [ABSTRACT FROM AUTHOR]

Peripheral artery disease (PAD) and heart failure (HF) share many risk factors; however, the prevalence and characteristics of HF in patients with PAD have not been fully examined. We investigated 120 consecutive patients with PAD, defined by an ankle-brachial index ≤0.9. In all, 36 (30%) patients had brain natriuretic peptide (BNP) levels ≥100 pg/mL (high BNP group), and 84 (70%) patients had BNP levels <100 pg/mL (low BNP group). Univariate analysis showed that high BNP was associated with age, estimated glomerular filtration rate, hypertension, and transmitral E-wave/early diastolic mitral annular velocity (E/e′) ratio. Multivariate logistic regression analysis established that a high BNP was strongly and independently associated with the highest quartile of E/e′, highlighting these patients’ diastolic dysfunction. The prevalence of high BNP levels in patients with PAD suggests that routine BNP measurements might be useful to detect HF. [ABSTRACT FROM PUBLISHER]
