BACKGROUND Pulmonary arterial hypertension (PAH) is a well-known complication of systemic sclerosis (SSc). Doppler echocardiographic screening for the detection of PAH (by measuring right ventricular systolic pressure [RVSP]) is therefore recommended for all patients with SSc. However, the validity of RVSP as a predictor of mortality in patients with SSc is(More)
BACKGROUND Resolution of left atrial thrombus after long-term oral anticoagulation enhances safe percutaneous transvenous mitral commissurotomy (PTMC); however, the short-term benefit has not been defined. OBJECTIVES To estimate the resolution rate of left atrial thrombus among PTMC candidates after 6 months of oral anticoagulation and to determine its(More)
OBJECTIVES We sought to develop a prognostic model to predict the disappearance of left atrial thrombi (LAT) among candidates for percutaneous transvenous mitral commissurotomy (PTMC). BACKGROUND Complete LAT resolution can be achieved with oral anticoagulation, allowing a number of patients to safely undergo PTMC. METHODS We randomly allocated 108 PTMC(More)
BACKGROUND Cardiac troponin T level (cTnT) is commonly increased in end stage chronic kidney disease (CKD) in the absence of acute myocardial infarction. There are few data available on serum cTnT concentration in patients with pre-end stage CKD. OBJECTIVE To evaluate the correlation of cTnT level and severity of kidney disease in patients with CKD stage(More)
BACKGROUND PCI is increasingly performed in patients with ULMCA disease. The efficacy and safety of drug-eluting stents in ULMCA disease have been reported. OBJECTIVE To evaluate the early and mid-term clinical outcome of the Percutaneous Coronary Intervention (PCI) with Drug-Eluting stent (DES) in unprotected left main coronary artery (ULMCA) disease(More)
BACKGROUND AND AIMS OF THE STUDY Little is known of the fate of left atrial thrombus (LAT) among candidates for percutaneous transvenous mitral commissurotomy (PTMC) after oral anticoagulation (OA) therapy. The aim of this study was to estimate the resolution rate of documented LAT, and to determine its significant predictors among this population. (More)
OBJECTIVE To determine baseline prognostic factors of in-hospital mortality in Thai patients with non-ST-elevation acute coronary syndrome (NSTE-ACS). MATERIAL AND METHOD Among 5,537 NSTE-ACS patients enrolled in Thai Acute Coronary Syndrome Registry, a univariate analysis and multivariate analysis were used to estimate the relationship of baseline(More)
BACKGROUND Systemic embolism is one of the major complications in patients with mitral stenosis (MS) who are in atrial fibrillation; however, this serious complication can also occur in patients with MS in sinus rhythm. OBJECTIVE The purpose of the present study was to identify the predictive factors of systemic emboli in patients with MS in sinus rhythm.(More)
OBJECTIVE Anticoagulation therapy is strongly recommended in all patients with mitral stenosis (MS) in atrial fibrillation (AF) but this treatment is controversial in patients in sinus rhythm (SR). The objective of the present study was to investigate the coagulation activity in patients with MS in sinus rhythm compared to those in atrial fibrillation. (More)
