The purpose of this study was to compare the effects of a sitting shower versus a sitting sink bath in low-risk patients with myocardial infarction (MI). Heart rate, blood pressure (mean blood pressure and rate-pressure-product), ratings of perceived exertion, and occurrence of symptoms during the baths and between resting, bathing, and recovery periods were evaluated. Thirty patients with MI were tested during their first and second self-bath on 2 consecutive days between 2 and 9 days after MI. The bathing methods produced significant increases from the resting values in all the variables (p less than or equal to 0.05). No significant differences between the resting and recovery values existed (p greater than 0.05). Ten subjects experienced atypical responses to bathing as indicated by heart rate and blood pressures. Fatigue was the most frequently encountered symptom at rest and during the bathing activities. The findings suggest that low-risk patients with MI can choose between a sitting sink bath or a sitting shower as their first self-bath after MI, based on preferences. However, because the bathing activity (and not the bathing method) did produce some atypical responses in one third of the subjects, readiness to engage in bathing activities should be individually assessed by objective and subjective criteria.
本研究的目的是比较坐式淋浴与坐式坐浴对低风险心肌梗死（MI）患者的影响。评估了心率、血压（平均血压和率压积）、主观用力程度评分以及沐浴期间和休息、沐浴及恢复阶段出现症状的情况。30例心肌梗死患者在心肌梗死后2至9天内连续两天的首次和第二次自行沐浴期间接受测试。所有变量的沐浴后值均较静息值显著升高（p≤0.05）。静息值与恢复值之间无显著差异（p＞0.05）。10名受试者的心率和血压显示对沐浴有非典型反应。疲劳是静息时和沐浴活动期间最常出现的症状。研究结果表明，低风险心肌梗死患者可根据个人喜好在心肌梗死后首次自行沐浴时选择坐式坐浴或坐式淋浴。然而，由于在三分之一的受试者中沐浴活动（而非沐浴方式）确实产生了一些非典型反应，因此应通过客观和主观标准对参与沐浴活动的准备情况进行个体评估。
