Abstract

BACKGROUND AND OBJECTIVE

Patients have reported that they perceive their own heart sounds differently after open cardiac surgery than before the surgery. The present study was designed to investigate whether changes in heart sounds can be quantitatively measured.

METHOD

Heart sounds were recorded from 57 patients undergoing coronary artery bypass graft (CABG) surgery and from a control group of 10 subjects. The so-called Hjorth descriptors and the main frequency peak were compared before and after surgery to determine whether the characteristics of the heart sounds had changed.

RESULTS

At a group level, the first heart sound was found to be significantly different after CABG surgery. Generally, the heart sounds shifted toward a lower frequency after surgery in the CABG group. No significant changes were found in the control group.

CONCLUSIONS

Heart sounds are altered after CABG surgery. The changes are objectively quantifiable and may also be subjectively perceived by the patients.

摘要

背景与目的

患者报告称，他们在心脏直视手术后对自身心音的感知与手术前不同。本研究旨在调查心音变化是否可以进行定量测量。

方法

记录了57例行冠状动脉旁路移植术（CABG）的患者以及10名受试者组成的对照组的心音。比较手术前后所谓的约尔特描述符和主要频率峰值，以确定心音特征是否发生了变化。

结果

在组水平上，发现冠状动脉旁路移植术后第一心音有显著差异。一般来说，冠状动脉旁路移植术组术后心音向较低频率偏移。对照组未发现显著变化。

结论

冠状动脉旁路移植术后心音发生改变。这些变化可以客观地量化，患者也可能主观感觉到。
