BACKGROUND Malignancy-associated thoracic radiation leads to radiation-associated cardiac disease (RACD) that often necessitates cardiac surgery. Myocardial dysfunction is common in patients with RACD. We sought to determine the predictive value of global left ventricular ejection fraction and long-axis function left ventricular global longitudinal strain(More)
BACKGROUND Left atrial volume (LAV) and exercise capacity are important prognostic determinants of cardiovascular risk. Exercise intolerance and increased LAV are expected in patients with diastolic dysfunction. While dyspnea is the symptom reported by the patient and considered subjective, exercise capacity obtained by exercise testing provides an(More)
BACKGROUND Standard aortic root dimensional measurement by the two dimensional echocardiography should be routinely performed in all patients. There is limited data on the normal reference on Thai population. OBJECTIVE Aims of this study were (1) to determine the normal reference of aortic root dimension in Thai population and (2) to determine the(More)
BACKGROUND Cardiac allograft vasculopathy (CAV), a major cause of graft failure and mortality at >3 years after orthotopic heart transplantation (OHT), is commonly evaluated using dobutamine stress echocardiography (DSE). We sought to study: (a) the incidence of positive results and diagnostic accuracy of DSE; and (b) the predictors of adverse outcomes in(More)
BACKGROUND Patients with non ST-segment elevation acute coronary syndrome (NSTEACS) present with diverse clinical, electrocardiographic, cardiac biomarker, echocardiographic and angiographic characteristics. We sought to determine whether there was any difference in the indices of left ventricular systolic and diastolic function among subgroups of patients(More)
BACKGROUND AND OBJECTIVE Echocardiography is usually performed to quantify the severity of regurgitation. Magnetic resonance imaging (MRI) can also quantify mitral regurgitation. This study was performed to determine whether MRI can reliably quantify the severity of mitral regurgitation when compared with echocardiography MATERIAL AND METHOD The authors(More)
BACKGROUND Pericardiectomy is an effective intervention for constrictive pericarditis. Speckle-tracking echocardiography can provide quantitative information not only about longitudinal strain (LS) but about longitudinal displacement (LD) and septal-to-lateral rotational displacement (SLRD). The aim of this study was to investigate whether pericardiectomy(More)
Patients undergoing maintenance hemodialysis develop both structural and functional cardiovascular abnormalities. Despite improvement of dialysis technology, cardiovascular mortality of this population remains high. The pathophysiological mechanisms of these changes are complex and not well understood. It has been postulated that several non-traditional,(More)
