■本研究的主要目的是证明术前右心室自由壁纵向应变(RVFWLS)和术前/术后应变变化(δ应变)与临床和超声心动图诊断右心室功能障碍的相关性。其次要目的是确定RVFWLS和delta菌株与重症监护病房(ICU)住院时间(LOS)的相关性,通风天数,利钠肽试验的趋势。前48小时(NT-proBNP)和乳酸,急性肾功能衰竭的发病率,28天死亡率

■无。
■在基线时收集所有临床和经食管超声心动图(TEE)参数,手术前(T1)和术后ICU入院时(T2)。在术后期间,右的临床和超声心动图诊断,左,或评估双心室功能障碍。TEE参数由心脏病专家离线评估。根据任何类型的心室功能障碍的发展,将患者分为两个亚组。两组之间无统计学差异。根据逻辑回归模型,-15%的T1-RVFWLS值似乎可预测双心室功能障碍(敏感性:100%;特异性:91.3%).T1-或T2-RVFWLS与肌酐无相关性,发现通气数小时或ICULOS。
■我们的研究引入了一个新的参数,可用于围手术期评估,以识别有术后双心室功能障碍风险的患者。
UNASSIGNED: This
study\'s primary purpose was to demonstrate the correlation of preoperative right ventricular free-wall longitudinal strain (RVFWLS) and pre-/postsurgical variation in strain (delta strain) with the clinical and echocardiographic diagnosis of right ventricular dysfunction. Its secondary purpose was to determine the correlation of RVFWLS and delta strain with length of stay (LOS) in the intensive care unit (ICU), ventilation days, trend of natriuretic peptide test. (NT-proBNP) and lactate in the first 48 h, incidence of acute renal failure, and 28-day mortality.
UNASSIGNED: Prospective observational
study.
UNASSIGNED: Cardio-thoracic and Vascular Anaesthesia Department and ICU of the University Hospital Integrated Trust of Verona.
UNASSIGNED: Patients scheduled for mitral surgery.
UNASSIGNED: None.
UNASSIGNED: All clinical and transoesophageal echocardiographic (TEE) parameters were collected at baseline, before surgery (T1) and at admission in the ICU postsurgery (T2). During the postoperative period, the clinical and echocardiographic diagnoses of right, left, or biventricular dysfunction were evaluated. TEE parameters were evaluated by a cardiologist offline. The patients were divided into two subgroups according to the development of any type of ventricular dysfunction. No statistically significant differences emerged between the two groups. According to a logistic regression model, a T1-RVFWLS value of -15% appeared to predict biventricular dysfunction (sensitivity: 100%; specificity: 91.3%). No correlation between T1- or T2-RVFWLS and creatinine, hours of ventilation or ICU LOS was found.
UNASSIGNED: Our
study introduces a new parameter that could be used in perioperative evaluations to identify patients at risk of postoperative biventricular dysfunction.
