Abstract

Inflammation and malnutrition are common problems in patients who are hospitalized for acute heart failure (AHF). C-reactive protein (CRP) is an acute-phase reactant and nonspecific marker for evaluating systemic inflammation. There has been growing interest in prealbumin for nutritional assessment. Additionally, prealbumin is a negative acute-phase protein because its synthesis is suppressed in the inflammatory setting in which cytokines stimulate hepatic production of acute-phase proteins (e.g. CRP). Therefore, the CRP to prealbumin ratio (CP ratio) may be a comprehensive marker of inflammation and malnutrition. We evaluated the relationship of the CP ratio with mortality in patients with AHF. We analyzed 257 hospitalized patients with AHF who had CRP and prealbumin levels examined on admission. The median CP ratio on admission was 0.57, with an interquartile range of 0.11 to 1.94. In receiver operating characteristic curve analysis, the area under the curve was 0.729 and the optimal cut-off point of the CP ratio for all-cause death was >1.60 (sensitivity: 67.5%; specificity: 77.6%; p = 0.003). Kaplan-Meier survival curves showed that patients with a high CP ratio (>1.60) had a significantly greater risk of all-cause, cardiac...Continue Reading

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.
