There is evidence that there is a bidirectional relationship between major depression and cardiovascular disorder (CVD): depressed patients are a population at risk for increased cardiac morbidity and mortality, and depression is more frequent in patients who suffer from CVD. There is also evidence that inflammatory and oxidative and nitrosative stress(More)
Percutaneous transluminal coronary angioplasty (PTCA) and coronary artery bypass grafting (CABG) are both used widely for angina but information about their comparative efficacy is limited. This study compared the outcome of 358 consecutive patients undergoing initial revascularization for significant narrowing of the left anterior descending artery (LAD)(More)
BACKGROUND Coronary magnetic resonance angiography is a noninvasive method to visualize coronary arteries. The objective of this study was to determine the accuracy of coronary magnetic resonance imaging in the detection of coronary artery stenosis. METHOD The authors studied 61 patients who were scheduled for their first diagnostic X-ray coronary(More)
The objective of this investigation was the assessment of the response rate of oral atenolol in patients with vasovagal syncope after 1 month of treatment. We randomized into two groups all patients referred to our unit who had had at least one episode of syncope or two episodes of presyncope 1 month before presentation and had a positive isuprel Tilt Table(More)
Prior to exercise treadmill testing (ETT), 157 patients (92 males and 65 females) were interviewed twice separately, using a Thai version of the Rose questionnaire for angina pectoris. One interview was conducted by a physician and the other by a nurse. The questionnaire responses were compared with ETT results. Based on physician-conducted interview, the(More)
The role of Chlamydia pneumoniae infection in precipitating acute coronary syndrome (ACS) is unclear. Some studies have indicated that intervention with macrolide antibiotics might reduce coronary events in patients with ACS. A double blind, randomized, placebo-control trial was conducted on 84 ACS patients. Patients were randomized to 30 days of treatment(More)
Association between obesity and conventional risk factors for coronary artery disease is well established. Obesity is currently considered an independent risk for coronary artery disease. The relationship between body mass index (BMI) and fasting plasma lipids and glucose and blood pressures in non-obese subjects is not established. The authors studied(More)
Chlamydia pneumoniae (C. pneumoniae) is an emerging infectious agent, with a spectrum of clinical manifestations, and it has recently been tentatively linked to atherosclerosis. In order to describe the seroprevalence of C. pneumoniae in Thailand, we evaluated 1,798 normal healthy subjects (aged 20-93 years) for anti-C. pneumoniae IgG and IgA. Specific(More)
Physical inactivity has been counted as a risk factor for coronary artery disease. Regular exercise has also been reported to reduce risk of cardiovascular disease and its risk factors. We surveyed 3615 subjects for their conventional risk factors of coronary disease and for the frequency of their exercise. We found that subjects who had regular exercise(More)
BACKGROUND Enhanced external counterpulsation (EECP) enhances coronary perfusion and reduces left ventricular afterload. However, the role of EECP on renal function in cardiac patients is unknown. Our aim was to assess renal function determined by serum cystatin C in cardiac patients before and after EECP treatment. METHODS A prospective observational(More)
