The p.K56M variant and risk of heart failure in chronic kidney disease: the Chronic Renal Insufficiency Cohort study.

Background: Intercellular adhesion molecule-1 (ICAM-1) is a cell-surface protein that facilitates inflammation through leucocyte adhesion. Approximately 35% of Black individuals carry at least one copy of an missense variant (rs5491; p.K56M), which has been associated with increased risk of heart failure (HF) with preserved ejection fraction (HFpEF).

Prognostic utility of rhythmic components in 24-hour ambulatory blood pressure monitoring for the risk stratification of chronic kidney disease patients with cardiovascular co-morbidity.

Background: Chronic kidney disease (CKD) represents a significant global burden. Hypertension is a modifiable risk factor for rapid progression of CKD.

Methods: We extend the risk stratification by introducing the non-parametric determination of rhythmic components in 24-hour profiles of ambulatory blood pressure monitoring (ABPM) in the African American Study for Kidney Disease and Hypertension (AASK) cohort and the Chronic Renal Insufficiency Cohort (CRIC) using Cox proportional hazards models.
