Aims Takotsubo syndrome (TTS) is associated to serious adverse in-hospital complications. We evaluated the role of invasively assessed left ventricular end-diastolic pressure (LVEDP) for predicting in-hospital complications in TTS patients compared to the most widely used echocardiographic parameters of ventricular function. Methods and Results We prospectively enrolled 130 patients (mean age 71.2 ± 11.3 years, 114 [87.7%] female) with TTS. Invasive measurement of LVEDP was performed at the time of cardiac catheterization. The rate of in-hospital complications (composite of acute heart failure, life-threatening arrhythmias and all-cause death) was examined. In-hospital complications occurred in 37 (28.5%) patients. Patients who experienced in-hospital complications had a higher prevalence of neurological trigger and lower prevalence of emotional trigger, higher LVEDP and mean E/e′ ratio and lower LV ejection fraction (LVEF) values compared to those who did not experience in-hospital complications. At multivariate logistic regression, higher LVEDP [odds ratio (OR) 1.12, 95% confidence interval (CI) [1.05–1.20], P < 0.001] and lower LVEF (OR 0.95, 95% CI [0.91–0.99], P = 0.011) remained independently predictors of in-hospital complications, while emotional trigger was associated to a lower risk (OR 0.24, 95% CI [0.06–0.96], P = 0.044). The area under the curve (AUC) for LEVDP in the prediction of in-hospital events was 0.776 (95% CI [0.69–0.86], P <0.001, with a sensitivity and specificity of 95% and 58% using a LVEDP cut-off value of 22.5 mmHg). The AUC was significantly higher for LVEDP than for E/e′ ratio (P = 0.037). Conclusions LVEDP measured at the time of catheterization may help in identifying TTS patients at higher risk of cardiovascular deterioration with relevant therapeutic implications.

左心室舒张末期压力可预测 takotsubo 综合征的住院结局

目的 Takotsubo 综合征 (TTS) 与严重的院内不良并发症有关。与最广泛使用的心室功能超声心动图参数相比,我们评估了侵入性评估的左心室舒张末期压力 (LVEDP) 在预测 TTS 患者住院并发症中的作用。方法和结果 我们前瞻性地招募了 130 名 TTS 患者(平均年龄 71.2 ± 11.3 岁,114 名 [87.7%] 女性)。在心导管插入术时进行 LVEDP 的侵入性测量。检查了住院并发症的发生率(急性心力衰竭、危及生命的心律失常和全因死亡)。37 名 (28.5%) 患者出现院内并发症。与未发生院内并发症的患者相比,发生院内并发症的患者神经系统触发发生率较高,情绪触发发生率较低,LVEDP 和平均 E/e' 比值较高,左室射血分数 (LVEF) 值较低. 在多元逻辑回归中,较高的 LVEDP [优势比 (OR) 1.12, 95% 置信区间 (CI) [1.05–1.20], P <; 0.001] 和较低的 LVEF (OR 0.95, 95% CI [0.91–0.99], P = 0.011) 仍然是院内并发症的独立预测因子,而情绪触发与较低的风险相关 (OR 0.24, 95% CI [0.06– 0.96],P = 0.044)。LEVDP 预测住院事件的曲线下面积 (AUC) 为 0.776 (95% CI [0.69–0.86], P <0.001,使用 LVEDP 切割的敏感性和特异性分别为 95% 和 58% -off 值为 22.5 mmHg)。LVEDP 的 AUC 显着高于 E/e' 比 (P = 0.037)。结论 导管插入时测量的 LVEDP 可能有助于识别具有相关治疗意义的心血管恶化风险较高的 TTS 患者。
