A high BNP level, diabetes, female gender, a low albumin level, ABI and BMI are risk factors for CLI. In this study, differences in the levels of anatomical lesions and correlated risk factors were found between the CLI and IC groups.
Aim:The goal of the study was to investigate the relationships between coronary artery disease (CAD) and risk factors, including the serum levels of high-sensitivity C-reactive protein (hs-CRP), lipoprotein(a) (Lp(a)) and homocysteine, in Japanese patients with peripheral arterial disease (PAD). Methods: Coronary angiography was performed in 451 patients with PAD, among whom the prevalence and clinical characteristics of CAD were analyzed. A multiple logistic analysis was used to evaluate the relationships between CAD and the risk factors. The relationships between the severity of coronary arterial lesions and the risk factors were evaluated using multiple regression analysis. Results: The prevalence of CAD (≥ 70% luminal diameter narrowing or a history of CAD) and coronary artery stenosis (≥ 50%) was 55.9% and 74.1%, respectively, and the rate of CAD (≥ 70%) with single-, double-and triple-vessel disease was 25.9%, 13.5% and 10.6%, respectively. The prevalence of diabetes was higher among the patients with CAD than among those without. The serum levels of hs-CRP, Lp(a), and homocysteine were higher in the patients with CAD, whereas the estimated glomerular filtration rates and HDL-cholesterol levels were lower in these patients. According to the multiple logistic analysis, CAD was related to diabetes (hazard ratio [
Post-cardiotomy right ventricular failure is a serious complication that frequently results in adverse outcomes. We reviewed our experience with the Impella Recover RD (Impella Cardiosystems GMbH, Aachen, Germany). From January 2007 to December 2007, 7 patients (5 males, 54 +7 years old) had this device implanted for temporary support after heart transplantation in 4, after repeat mitral valve replacement in 2, and with a left ventricular assist device in 1. Devices were implanted during initial operation (n =5) or shortly thereafter (n =2). Six patients underwent implantation without cardiopulmonary bypass. Effective support with pump flows of 4.0-4.5 L x min(-1) and adequate unloading (central venous pressure decreased from 15.3 +/- 1.4 to 9.4 +/- 1.2 mm Hg) was achieved in all patients. Patients were assisted for a mean duration of 4.9 +/- 4.5 days. Three patients could be weaned after 7.0 +/- 5.6 days of support and underwent device explantation without cardiopulmonary bypass. One of these patients died of recurrent right ventricular failure, 2 remained stable but died later of sepsis. The patient with a left ventricular assist device was switched to an alternative device for prolonged support. Two patients experienced pump dysfunction. Our preliminary experience shows that the Impella Recover RD is an effective device that can be easily implanted and explanted. However, its mechanical reliability needs to be improved.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
