Impact of Hospital Ward Acoustic Design on Postoperative Recovery of Patients with Acute Myocardial Infarction.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAcute myocardial infarction (AMI) is a critical condition requiring effective postoperative recovery management. Hospital noise, often exceeding recommended levels, can heighten stress and disrupt healing post-AMI. This study investigated the effects of acoustic design in hospital wards on postoperative recovery for patients with AMI.
methodsA retrospective analysis was conducted on 192 patients with AMI hospitalized between June 2021 and July 2023. Patients were allocated into two groups on the basis of ward design: an acoustically optimized ward (AOW, n = 91) and a conventional ward (CW, n = 101). Outcomes, including vital signs, sleep quality, patient perceptions, and recovery metrics, were assessed. Noise levels were monitored continually, and sleep quality was gauged using sleep diaries.
resultsThe AOW group exhibited significantly lower systolic (P = 0.011) and diastolic (P = 0.016) blood pressures and improved postoperative left ventricular ejection fraction (LVEF, P = 0.002) than the CW group, but LVEF was not reassessed at discharge. The AOW group further demonstrated reduced noise levels both day (P = 0.004) and night (P = 0.021), fostering better sleep outcomes such as fewer awakenings (P = 0.024). Additionally, the AOW group experienced shorter hospital stays (13.21 ± 3.57 days) than the CW group (14.34 ± 3.19 days, P = 0.022) and improved patient satisfaction at discharge (P = 0.029). Perceived pain was significantly reduced in the AOW group (P = 0.026). Anxiety levels displayed no significant differences.
conclusionThe acoustic optimization of hospital wards was associated with improvements in postoperative recovery outcomes, such as lower blood pressure, enhanced sleep quality, reduced perceived pain, and shorter hospital stays, for patients with AMI, suggesting that a good sound environment may play a positive role in postoperative recovery.
