aneurysms of the left main coronary artery are exceedingly rare clinical entities, encountered incidentally in approximately 0.1% of patients who undergo routine angiography. the most common cause of coronary artery aneurysms is atherosclerosis. angiography is the gold standard for diagnosis and treatment. depending on the severity of the coexisting coronary stenosis, patients with left main co...

Background and Objective: Coronary artery disease (CAD) is one of the most common diseases today. Among the diagnostic methods, angiography is the main and gold standard in the diagnosis Since angiography is an invasive procedure, this procedure complications range widely from minor problems with short term sequelae to life threatening ones may cause irreversible damage or even death. Materials...

the coronary slow flow phenomenon (csfp) is characterized by a delayed coronary blood flow in the absence of an obstructive coronary artery disease. although the relation between the csfp and myocardial ischemia has been reported previously, there is no knowledge about the relationship between the csfp and the conduction system disorder. in this case report, we describe a patient with the csfp ...

objectives to evaluate predictive value of vessel specific coronary artery calcium (cac) score in predicting obstructive coronary artery disease. patients and methods in this diagnostic test study we evaluated patients with coronary computed tomography angiography (ccta) and cac score which had been referred to two referral radiology center in tehran, iran and finally we selected 2525 patients ...

introduction: coronary endarterectomy is not a perfect procedure. however, it is sometimes the only available alternative for cardiac surgeons in patients suffering from diffuse coronary artery disease. according to a large volume of studies, coronary endarterectomy results (such as survival, recurrence of the symptoms of myocardial ischemia, and graft patency) are not as satisfactory as standa...

a 55-year-old man referred for cardiac resynchronization therapy (crt) due to severe heart failure. a severe stenosis in the coronary sinus vein after the posterior branch disallowed the insertion of the lead. nevertheless, the stenosis was dilated and the left ventricle (lv) lead was implanted in the lateral marginal branch.

Conophylline is a vinca alkaloid extracted from the tropical plant Ervatamia microphylla and has been shown to induce differentiation of pancreatic AR42J cells. In the present study, we investigated the effect of conophylline on the differentiation of pancreatic precursor cells. In the rat pancreatic rudiment in organ culture, conophylline inhibited the formation of cystic structure and increas...

conclusions in total, application of therapeutic approaches in patients with cad depends on many factors. in our study not only risk factors such as gender, lifestyle, smoking, alcohol abuse, diabetes and hypertension were associated with the incidence of cad, but also they were highly correlated with the severity of the disease. results the mean age of total patients was 58.3 ± 11.5 years (p =...

coronary artery anomalies are rare, with their incidence varying from 1 to 5%. angiography is a commonly used modality for the assessment of coronary artery anomalies. based on previous reports, a majority of coronary artery anomalies are of origin or distribution, with separate ostia of the left anterior descending artery and left circumflex artery. coronary artery anomalies may cause myocardi...

conclusions the eft, as measured by echocardiography, with a cut off value 2.95 mm has a strong association with premature cad. results among baseline characteristics, waist circumference, triglyceride levels, cigarette smoking and history of statin use were significantly higher in the cad group. the body mass index (bmi) was significantly higher in the non-cad group. according to echocardiogra...
