Positive association between Cheyne-Stokes respiration events and diastolic dysfunction in pre-heart failure: a cross-sectional study with longitudinal implications.

ABSTRACT:

Background

Cheyne-Stokes respiration (CSR), a distinct type of sleep-related breathing disorder, is closely associated with heart failure (HF). In clinical practice, it has been observed that some patients with CSR do not present with HF or related symptoms. However, limited studies have investigated this phenomenon. This study aimed to explore whether CSR events may indicate specific cardiac structural/functional alterations or serve as an early warning sign for HF progression.

Materials and methods

We enrolled middle-aged and elderly patients (≥45 years) hospitalized at Guangdong Provincial Hospital of Traditional Chinese Medicine without a diagnosis or symptoms of HF. Data on medical history, echocardiography, BNP/NT-proBNP levels, and polysomnography were collected. Part
