BACKGROUND Multi-slice computed tomography (MSCT) is a fast-growing technology that permits a non-invasive, yet reliable, assessment of coronary atherosclerosis. We sought to explore the diagnostic accuracy of MSCT angiography in the detection of significant stenosis of the left main coronary artery (LMCA) in a series of patients with an intermediate pre-test likelihood of coronary artery disea...

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...

conclusions cgm is a non-invasive technique recently developed for quantitative three-dimensional vectorial analysis of myocardial activity and detection of ischemia and infarction. this technique is clearly more sensitive and more specific than a standard resting 12-lead ecg. results the coronary angiography showed a normal coronary artery in 263 patients (67.4%). a median of cgm score was 1 (...

Coronary artery disease (CAD) is an important cause of morbidity and mortality worldwide and is associated with a sustained increase in vascular tone. Large conductance, voltage-dependent and calcium-activated potassium (K) channels, or BK channels determine membrane electrical activity in human coronary artery smooth muscle cells (HCASMCs). Their activation leads to hyperpolarization, a decrea...

OBJECTIVE Coronary calcium score (CCS), carotid plaque area (CPA), intima-media thickness (IMT), and C-reactive protein (CRP) are independent predictors of cardiovascular prognosis. Although each test may enhance risk stratification, their comparative abilities to screen for underlying coronary stenoses in individual patients is less established. METHODS AND RESULTS Forty-two patients who had...

Introduction: Neutrophil-to-lymphocyte ratio (NLR) is considered as an independent predictor of long-term prognosis in the individual patients with coronary artery disease (CAD). This study sought to assess the relationship between NLR and CAD severity in Iranian patients undergoing cardiac catheterization.Material and Methods: This prospective study was conducted on 500 patients with acute cor...

Background and Purpose: Coronary Artery Disease (CAD) is the major cause of limitation in adults' life. But it can be prevented by controlling its risk factors, modifying life style and educating the population about general health. Besides, health education is one of the important issues about changing life style. Nurses play an important role in health education .Thus this study was perform...
