U-shaped association between serum calcium and in-hospital mortality in patients with congestive heart failure.

ABSTRACT:

Aims

Serum calcium level is widely used for evaluating disease severity, but its impact on clinical outcomes in patients with congestive heart failure (CHF) remains poorly understood. The aim of this study is to investigate the relationship between serum calcium levels and in-hospital mortality in CHF patients.

Methods and results

We conducted a retrospective analysis utilizing clinical data from the Medical Information Mart for Intensive Care database, encompassing a cohort of 15 983 CHF patients. This cohort was stratified based on their serum calcium levels, with the primary objective being the determination of in-hospital mortality. To assess the impact of admission serum calcium levels on in-hospital mortality, we employed various statistical methodologies, including mu
