P-wave dispersion is defined as the difference between the maximum and the minimum P-wave duration recorded from multiple different-surface ECG leads. It has been known that increased P-wave duration and P-wave dispersion reflect prolongation of intraatrial and interatrial conduction time and the inhomogeneous propagation of sinus impulses, which are(More)
The clinical goals of risk stratification of sudden death are to identify subjects who are at high risk of, and eventually to reduce the incidence of, sudden death. Numerous studies have described risk stratification techniques for serious cardiac events in patients following myocardial infarction. However, relatively little information is available(More)
A 59-year-old man was admitted with unresolved chest pain after coronary artery bypass graft surgery that had been performed 3 years earlier; aorta-obtuse margina-lis, and aorta-posterior descending artery with the use of a saphenous vein graft and left anterior descending artery-left internal mammary artery (LIMA). He reported recurrent angina pectoris and(More)
Hypertrophic cardiomyopathy (HCM) is defined as myocardial hypertrophy in the absence of another cardiac or systemic disease capable of producing the magnitude of present hypertrophy. In about 70% of patients with HCM, there is left ventricular outflow tract (LVOT) obstruction (LVOTO) and this is known as obstructive type of hypertrophic cardiomyopathy(More)
Clinical trials of pharmacological therapies in acute heart failure syndromes: lessons learned and directions forward. Relationship between early physician follow-up and 30-day readmission among medicare beneficiaries hospitalized for heart failure. Sinus of Valsalva aneurysms (SVAs) are rare cardiac anomalies which may be acquired or congenital, most(More)
OBJECTIVE This study examined the effects of low dialysate sodium on endothelial dysfunction (ED) as measured by flow-mediated dilatation (FMD) of brachial artery in haemodialysis (HD) patients. METHODS Thirty HD patients (17 men; mean age: 48.4 ± 17.8 years) were studied. Subjects underwent two consecutive 6-week HD periods. Dialysate sodium was 143(More)
BACKGROUND Cardiac resynchronization therapy (CRT) has been shown to reduce heart failure-related morbidity and mortality. However, approximately one in three patients do not respond to CRT. The aim of the current study was to determine the parameter(s) which predict reverse remodeling and clinical improvement after CRT. METHODS A total of 54 patients (43(More)
