background: streptokinase, which is injected intravenously with a standard dose of 1.5 miu, is the most widely used thrombolytic agent around the world. what is so important about this bioproduct is the level of antistreptokinase (anti-sk) antibody in the population, which is directly correlated to the incidence of streptococcal infections in that population. objective: since iran is an endemic...

Background: Evidence suggests hypovitaminosis D is associated with increased risk of coronary artery disease (CAD) and its extent and related risk factors. However, some investigations have produced contrary results. Therefore, we aimed to evaluate the association between serum vitamin D levels and the severity of premature coronary artery involvement. Methods: This randomized prospective, cas...

discussion the reason is that we assess the relative and not absolute differences of the tracer uptake in this imaging modality. there may be other findings on mpi images which could help us overcome this pitfall, including detecting wall motion abnormalities, lung uptake of the tracer, or transient ischemic dilation. another important issue is the ecg changes during exercise stress testing, wh...

Obesity is a common public health problem and obese individuals in particular have a disproportionate incidence of acute coronary events. This study was undertaken to identify coronary artery lesions as well as associated clinical features, risk factors and demographics in patients with a body mass index (BMI) >40 kg/m(2) without known coronary artery disease (CAD). Morbidly obese subjects were...

Coronary artery disease (CAD) is the most common type of heart progression once major coronary arteries are injured or diseased. When primary blood which supply myocardium with blood, oxygen and nutrients narrowed arterial progresses. Plaque buildup in walls from hypercholesterolemia (high cholesterol), dyslipidemia, vascular inflammation contribute to atherosclerosis formation, a agent for CAD.

With better control of infective and metabolic complications, diabetes has emerged as a cardiovascular disease. The ATP III recognizes it as a CHD equivalent and the American Diabetes Association has categorized it as a cardiovascular disease. Unlike microvascular disease, which gets clicked with onset of diabetes, macrovascular disease, particularly coronary artery disease (CAD) predates the d...

OBJECTIVES This study sought to assess the incidence of transplant coronary artery disease (CAD) in Chinese heart recipients. BACKGROUND The prevalence of transplant CAD detected by angiography at 1, 2 and 4 years after heart transplantation was 11%, 22% and 45%, respectively. The incidence of transplant CAD in Chinese heart recipients has not been reported. METHODS For those recipients sur...

background: given gender differences in the risk of coronary artery disease (cad), the present study sought to investigate these dissimilarities amongst patients who underwent angiography at a major, tertiary heart hospital in iran. methods: between 2005 and 2010, 44,820 patients who underwent coronary angiography were enrolled in a registry. pre-procedural data such as demographics, cad risk f...
