Long-Term Mortality After Invasive Angiography and Endovascular Revascularization in Patients With PAD Having Chronic Kidney Disease

Abstract

Peripheral arterial disease (PAD) and chronic kidney disease (CKD) are associated with increased mortality rates. We assessed long-term outcomes of patients with PAD and CKD. Patients with PAD undergoing invasive angiography and/or endovascular revascularization between 2005 and 2010 were retrospectively classified into 5 CKD stages. A follow-up was performed and 572 patients were included, 116 patients (20%) had normal renal function, 245 were in CKD stage 2 (43%), 156 in CKD stage 3 (27%), and 55 in CKD stages 4 + 5 (10%). Diabetes mellitus, hypertension, and anemia were more frequent in higher CKD stages (P < .03). During follow-up (mean 1135 days; 95% confidence interval 1159-1259), cumulative mortality was 21% and increased with advanced CKD stages (9%, 16%, 29%, and 47%, respectively, P < .001). In multivariate Cox regression models, higher CKD stages were significantly associated with poor survival. Medication adherence for secondary prevention was significantly lower than recommended but irrespective of CKD stages. Kidney function is an independent predictor of worse long-term survival in patients with PAD. While standard medications were used less often than recommended, no differences between CKD stages were noted.

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.

Antihypertensive Agents: Mechanisms of Action

Antihypertensive drugs are used to treat hypertension (high blood pressure) which aims to prevent the complications of high blood pressure, such as stroke and myocardial infarction. Discover the latest research on antihypertensive drugs and their mechanism of action here.
