Positive evidence from clinical trials has fueled growing acceptance of traditional Chinese medicine (TCM) for the treatment of cardiac diseases; however, little is known about the underlying mechanisms. Here, we investigated the nature and underlying mechanisms of the effects of YiXin-Shu (YXS), an antioxidant-enriched TCM formula, on myocardial(More)
BACKGROUND Two-dimensional speckle tracking echocardiography (2DSTE) has been used widely in research, but rarely in clinical practice because data acquisition and analysis are time-consuming. By reducing the acquisition and analysis time, 3-dimensional STE may improve clinical impact. We investigated the feasibility of 3DSTE myocardial deformation, with(More)
Behçet's disease (BD) is a multi-system inflammatory disorder. We report the case of a BD patient with severe aortic root vasculitis. Two-dimensional transthoracic echocardiography (2DE) images suggested left Valsalva sinus aneurysm ruptured into the left ventricular outflow tract. However, preoperative transesophageal real-time 3-dimensional(More)
To investigate the impact of microvascular dysfunction assessed by angiography on myocardial deformation assessed by two-dimensional speckle-tracking echocardiography in ST-segment elevation myocardial infarction (STEMI). A total of 121 STEMI patients who received primary percutaneous coronary intervention were included. Thrombolysis in myocardial(More)
BACKGROUND Intramyocardial hemorrhage (IMH) and microvascular obstruction (MVO) are two major mechanisms of reperfusion injury of the left ventricle after acute ST-segment elevation myocardial infarction (STEMI). The aim of this study was to assess the impact of IMH and MVO on left ventricular (LV) cardiac mechanics using two-dimensional speckle-tracking(More)
Backgrounds: Despite their clear therapeutic benefits, anthracycline-induced cardiotoxicity is a major concern limiting the ability to reduce morbidity and mortality associated with cancers. The early identification of anthracycline-induced cardiotoxicity is of vital importance to assess the cardiac risk against the potential cancer treatment. Objective:(More)
A 63-year-old man was admitted because of current chest pain with perspiration for 6 hours. Electrocardiography showed complete right bundle-branch block and ST-segment elevation on leads II, III, aVF, and V 2 through V 6 (Figure 1); we therefore suspected an anterior and inferior wall acute myocardial infarction. Coronary angiography revealed total(More)
