Utilizing a registry for ST segment elevation myocardial infarction from a tertiary care hospital in Thailand: opportunities to improve the quality of care.

Background: Treatment of acute coronary syndrome requires a reliable measurement of quality for ensuring evidence-based care. Clinical registries have been used to support quality improvement activities in some countries, but there are few data concerning their implementation in developing countries. In 2008, a multidisciplinary Siriraj ST segment elevation myocardial infarction (STEMI) registry team was formed with the intention to improve the process of care.

Coronary-artery bypass surgery in patients with left ventricular dysfunction.

Background: The role of coronary-artery bypass grafting (CABG) in the treatment of patients with coronary artery disease and heart failure has not been clearly established.

Methods: Between July 2002 and May 2007, a total of 1212 patients with an ejection fraction of 35% or less and coronary artery disease amenable to CABG were randomly assigned to medical therapy alone (602 patients) or medical therapy plus CABG (610 patients). The primary outcome was the rate of death from any cause.

The effectiveness of "Siriraj Leg Lock" brace on back pain after percutaneous coronary intervention: PCI.

Background: The most common problem experienced by patients after Percutaneous Coronary Intervention (PCI) is back pain. After the procedure, patients are restricted to complete bed rest with no hip flexion for up to 10 hours, causing much discomfort, especially back pain. In some patients, anxiety arises due to limited movement, with the belief that movement might cause re-bleeding from the wound.

Early and intermediate outcomes of left main coronary intervention.

Objective: We examined the immediate and long-term outcomes after stenting of all comers for left main coronary artery (LMCA) stenoses.

Background: Left main coronary artery disease is regarded as an absolute contraindication for coronary angioplasty. Recently, several reports on protected or unprotected LMCA stenting, or both, suggested the possibility of percutaneous intervention for this prohibited area.

Stent placement compared with balloon angioplasty for obstructed coronary artery disease in Thai elderly patients: initial result and 6 months follow-up.

Unlabelled: Percutaneous Old Balloon Angioplasty (POBA) is accepted worldwide for the treatment of obstructive coronary artery disease because this technique is safe, and quick and the patient may return to work earlier than with bypass surgery (particularly elderly patients). But the major problem with POBA is restenosis which occurs between 20-40 per cent. Stent placement has been reported to reduce the restenosis rate to 10-20 per cent.

An abnormal systemic and regional hypercoagulable state in patients with mitral stenosis.

Mitral stenosis still remains a major problem in Southeast Asia including Thailand. It contributes to the morbidity and mortality related to thromboembolism which was associated with the left atrial thrombus. However, the pathogenesis of left atrial thrombus in these patients is not completely understood.

An electrocardiographic survey of elderly Thai people in the rural community.

Unlabelled: Electrocardiographic findings in the elderly reflect both common cardiac diseases and physiologic ageing change. This cross-sectional population-based study explored the prevalence of various abnormalities in the electrocardiograms of active older people and those who are free from any cardiac pathology and determined their relationship to age and gender in a rural area of Thailand. Nine hundred and sixty three people aged 60 years or more were recruited.

Efficacy and safety of percutaneous metallic mitral valvuloplasty in rheumatic mitral stenosis at Siriraj Hospital.
