# Elevated Soluble ST2 Blood Levels in Patients with Depression and Comorbid Heart Failure: A Correlative Study

## TL;DR

This study finds that patients with heart failure and depression have higher levels of a blood marker called soluble ST2 compared to those without depression.

## Contribution

The study identifies a novel correlation between depression and elevated soluble ST2 levels in heart failure patients.

## Key findings

- Soluble ST2 levels were 1.6 times higher in heart failure patients with depression compared to those without.
- The correlation suggests soluble ST2 could serve as a potential biomarker for depression in heart failure patients.

## Abstract

Depressive disorders frequently coexist with chronic medical conditions like heart failure (HF), significantly impacting patients’ overall health and quality of life. This study aims to explore the correlation between soluble ST2 molecule levels and the presence of depressive disorders in patients with heart failure.

A total of 200 patients, all diagnosed with heart failure, were included in this study. Among them, 30 patients were mentally healthy, and the remaining 170 exhibited medium-level depressive disorders. Blood samples were collected and analyzed for soluble ST2 levels to assess the potential correlation between depressive disorders and soluble ST2 levels in patients with heart failure.

A total of 200 patients, all diagnosed with heart failure, were included in this study. Among them, 30 patients were mentally healthy, and the remaining 170 exhibited medium-level depressive disorders. Blood samples were collected and analyzed for soluble ST2 levels to assess the potential correlation between depressive disorders and soluble ST2 levels in patients with heart failure.

The study demonstrated a statistically significant finding, indicating that the levels of soluble ST2 were 1.6 times higher in patients with depression and comorbid heart failure compared to mentally healthy individuals with heart failure.

This study elucidates a statistically significant correlation between medium-level depressive disorders and elevated soluble ST2 levels in patients with coexisting heart failure, shedding light on the potential role of soluble ST2 as a biomarker in identifying and managing depressive disorders in heart failure patients. The observed 1.6-fold increase in soluble ST2 levels in heart failure patients with depression emphasizes the importance of mental health assessment and intervention in individuals with chronic medical conditions, particularly heart failure, to enhance overall care and outcomes.
