Abstract

In this exploratory analysis of 35 patients with ischemic cardiogenic shock, we evaluated the correlation between tricuspid regurgitation velocity (TRV) and pulmonary artery catheter-derived pressures. TRV correlated best with pulmonary artery mean pressure (r = 0.54, p = 0.0009), more than with systolic or diastolic pressures. A TRV threshold of 2.3 m/s identified mean pressure >25 mmHg with 81% sensitivity and 62% specificity. These findings suggest that TRV may serve as a non-invasive indicator of elevated pulmonary pressure in critically ill patients when invasive monitoring is unavailable. Further validation in larger, diverse cohorts is needed.

心源性休克时三尖瓣反流速度比收缩压更能反映肺动脉平均压。

在对35例缺血性心源性休克患者的探索性分析中，我们评估了三尖瓣反流速度（TRV）与肺动脉导管源性压力的相关性。TRV与肺动脉平均压相关性最好（r = 0.54, p = 0.0009），高于与收缩压和舒张压相关性。TRV阈值为2.3 m/s，以81%的灵敏度和62%的特异性识别平均压力bbb25 mmHg。这些发现表明，在无法进行有创监测的危重患者中，TRV可作为肺动脉高压升高的非创性指标。需要在更大的、不同的队列中进一步验证。

期刊介绍： The Journal of the Intensive Care Society (JICS) is an international, peer-reviewed journal that strives to disseminate clinically and scientifically relevant peer-reviewed research, evaluation, experience and opinion to all staff working in the field of intensive care medicine. Our aim is to inform clinicians on the provision of best practice and provide direction for innovative scientific research in what is one of the broadest and most multi-disciplinary healthcare specialties. While original articles and systematic reviews lie at the heart of the Journal, we also value and recognise the need for opinion articles, case reports and correspondence to guide clinically and scientifically important areas in which conclusive evidence is lacking. The style of the Journal is based on its founding mission statement to ‘instruct, inform and entertain by encompassing the best aspects of both tabloid and broadsheet''.
