Abstract

Full, as compared with partial, correction of anaemia did not reduce the mortality risk in patients with chronic kidney disease (CKD), although the underlying mechanisms are unknown. Since CKD is a high-risk population for cardiovascular disease (CVD), we tested a hypothesis that the presence of atherosclerosis affects the relationship between anaemia and mortality risk. We performed a single-centre 10-year follow-up study with an observational cohort of 505 haemodialysis patients to analyse the relationship between haematocrit and all-cause mortality. Baseline haematocrit levels did not differ between the 153 patients with CVD and the 352 patients without CVD. During the follow-up, 268 patients died. Both Kaplan-Meier and univariate Cox analyses showed that higher haematocrit levels were a significant predictor of lower risk of death in the CVD (-) group, whereas haematocrit did not predict death in the CVD (+) group. In multivariate Cox analyses, the inverse relationship between haematocrit and mortality in the CVD (-) group remained significant and independent of 14 covariates including the use of erythropoietin. In contrast, using the same Cox models, the CVD (+) group did not show such a beneficial effect of higher haemato...Continue Reading

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.

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.

Atherosclerosis Disease Progression

Atherosclerosis is the buildup of plaque on artery walls, causing stenosis which can eventually lead to clinically apparent cardiovascular disease. Find the latest research on atherosclerosis disease progression here.
