Background: Coronary heart disease is a rising cause of adult death in Nepal. Diagnostic and interventional facilities such as coronary angiography and angioplasty have also collaterally improved in Nepal over the last decade. This study explores the most common coronary vessels involved in the Nepalese population based on the coronary angiographic findings. Methods: This is a retrospective stu...

Introduction: One of the most effective means for treatment of coronary arteries cramp (CHD) is coronary intravascular Brachiotherapy. In this study, with use of MCNP code, in order to invastigating the score of ditribution of absorbed dose, drope in dose, and simulation mean, radiation doses around iridium_192 radioactive has been done.   Materials and Methods:</str...

Coronary heart disease has been one of the main threats to human health. Coronary angiography is taken as the gold standard; for the assessment of coronary artery disease. However, sometimes, the images are difficult to visually interpret because of the crossing and overlapping of vessels in the angiogram. Vessel extraction from X-ray angiograms has been a challenging problem for several years....

OBJECTIVE Percutaneous coronary intervention with drug-eluting stents is challenging coronary artery bypass grafting (CABG) as the gold standard for treatment of three-vessel and left main coronary disease. We evaluated the current practice pattern in hospitals throughout Europe and USA. METHODS To qualify for participation in the SYNTAX (Synergy between PCI with TAXUS drug-eluting stent and ...

OBJECTIVES The aim of this study was to examine the ability of exercise single-photon emission computed tomographic (SPECT) thallium imaging to identify high risk women with left main or three-vessel coronary artery disease using a stepwise discriminant analysis. BACKGROUND Previous studies have used statistical methods to identify high risk men with coronary artery disease. Only limited data...

BACKGROUND Direct noninvasive visualization of the coronary vessel wall may enhance risk stratification by quantifying subclinical coronary atherosclerotic plaque burden. We sought to evaluate high-resolution black-blood 3D cardiovascular magnetic resonance (CMR) imaging for in vivo visualization of the proximal coronary artery vessel wall. METHODS AND RESULTS Twelve adult subjects, including...

PURPOSE Many patients admitted for acute myocardial infarction (AMI) have chronic renal insufficiency and erectile dysfunction (ED). This study aimed to evaluate the relationship between ED and the glomerular filtration rate (GFR) in patients with coronary artery disease. MATERIALS AND METHODS We studied 183 patients undergoing coronary angiography owing to AMI. The GFR was calculated and the...

A 69-year-old patient with unstable angina presented to cardiac catheterization with a tight lesion in the mid right coronary artery (Figure 1A) and moderate lesions in the left main and left anterior descending coronary arteries. During coronary angioplasty, a stent was electively implanted in the right coronary artery, with good initial results. However, during subsequent aggressive, high-pre...

BACKGROUND The prevalence of coronary vessel wall alterations in the general population is not known. Therefore, the aim of our study was to determine the prevalence of coronary artery disease in persons in whom the underlying disease was not related to coronary artery disease and could therefore be regarded as a near normal population. METHODS We included 331 consecutive patients (173 men, 1...

The purpose of our study was to determine differences in coronary lesions after myocardial infarction between Japan and Western countries. One hundred ninety-two patients under 69 years of age admitted to our CCU were diagnosed as having an acute myocardial infarction. One hundred thirty of 153 surviving patients received coronary arteriography, and 12% had zero-vessel, 42% single-vessel, 25% t...
