UNASSIGNED: The inclusion criteria were ischemic cardiomyopathy with left ventricular ejection fraction of <40% diagnosed using standard 2DE, 2D-STE, and 3DE examination. Patients were followed for 6 years, and cardiac mortality was recorded.
UNASSIGNED: The study sample comprised a total of 54 participants. During the period of follow-up, 24% (13/54) died. The 2DE models showed that being older, having a higher body mass index (BMI), having higher systolic pulmonary artery pressure (SPAP), and a lower RV global longitudinal strain were associated with cardiac mortality in our cohort after 6-year follow-up. Finally, the 3DE models showed that in addition to being older, having higher BMI, having a higher SPAP baseline, lower baseline 3DE RV stroke volume, and larger 3DE RV end-diastolic volume and 3DE RV end-systolic volume were associated with cardiac mortality over 6-year follow-up.
UNASSIGNED: This study provides evidence that RV dysfunction as seen on 2D-STE and 3DE could be associated with increased risk of cardiac-related mortality in patients with heart failure over 6 years.
■纳入标准为使用标准2DE诊断左心室射血分数<40%的缺血性心肌病,2D-STE,3DE检查。患者随访6年,并记录心脏死亡率.
■研究样本共有54名参与者。在后续行动期间,24%(13/54)死亡。2DE模型显示年龄较大,具有较高的体重指数(BMI),具有较高的收缩期肺动脉压(SPAP),在我们的队列中,6年随访后,较低的RV整体纵向应变与心脏死亡率相关.最后,3DE模型显示,除了年龄较大,有较高的BMI,具有较高的SPAP基线,较低基线3DE右心室每搏输出量,更大的3DERV舒张末期容积和3DERV收缩末期容积与6年随访期间的心脏死亡率相关。
■这项研究提供了证据,证明在2D-STE和3DE上观察到的RV功能障碍可能与6年以上心力衰竭患者的心脏相关死亡风险增加有关。
