Relationship between Noise Exposure and Prognosis of Patients with Heart Failure: A Retrospective Analysis.

Background: Environmental noise damages the cardiovascular system and endangers human health. This study was conducted to analyze the relationship between noise exposure and prognosis of patients with heart failure and to provide a good strategy for disease treatment.

Methods and materials: This study was a retrospective analysis. A total of 487 patients with heart failure admitted to Ganzhou People's Hospital from September 2021 to September 2023 were selected as research subjects, and they were divided into the low noise exposure group (<55 dB; group A) and the high noise exposure group (≥55 dB; group B) according to the noise exposure conditions. The baseline data and physiological indicators of the two groups were analyzed.

Results: In this study, 84 patients were included in group B, and the remaining 403 patients were included in group A. Group A had lower systolic pressure, diastolic pressure, heart rate, and respiratory rate compared to group B (P < 0.05). The serum B-type natriuretic peptide (BNP) level in group A was lower than that in group B (P < 0.001). Group B had significantly higher scores on the Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) compared to group A (P < 0.001). The noise level was correlated with SAS score, SDS score, and serum BNP level (all P < 0.001).

Conclusion: The noise exposure is correlated with the prognosis of patients with heart failure, suggesting that active strategies should be adopted to reduce the impact of noise on their disease.
