Background: Assessing the trend of ischemic heart diseases and the process of acute coronary care is one of the most important tools in monitoring the programs dedicated to control of ischemic diseases. The current project was developed to assess the feasibility of using routine data registered in clinical records for coronary event registration according to the standards of WHO/MONICA project....
Background & Aim :Low density lipoprotein (LDL) particles are heterogenous with respect to their size,density and lipid composition. Among LDL particles ,the smaller and denser LDLs (small dense (sd)LDL) are believed to be atherogenic since these particles are taken up more easily by arterial wall.They are readily oxidized and have reduced affinity for LDL receptor and increased affinity for ...
Introduction: QT dispersion (QT Max – QT min) reflects inhomogeneous ventricular depolarization that may provide a substrate for serious arrythmias and is associated with adverse clinical outcomes in patients with coronary artery disease. Some studies have shown reduction in QT dispersion after successful angioplasty due to coronary reperfusion, but effect of coronary artery bypass grafting o...
Background & Aims:Over the last decade, cardiovascular disease (CVD) has become the single largest cause of death worldwide including all developing regions. The coronary artery disease (CAD) is the most lethal form of CVD. Ceruloplasmin is a ferroxidase enzyme with two paradoxically oxidative and antioxidative performances. Some studies show that ceruloplasmin give rise to atherosclerosis...
Background: Multislice computed tomography (MSCT) is a noninvasive method of detecting coronary artery disease (CAD). The purpose of the present study was to investigate the accuracy of 64-slice MSCT (64-MSCT) in daily practice, without patient selection. Methods: Sixty-four consecutive suspected CAD patients underwent both 64-MSCT and quantitative coronary angiography (QCA). The CT system The...
background :in addition to diagnosing the acute myocardial infarction (mi), stratifying high-risk patients and proper treatment strategies are important issues in managing patients complaining of chest pain and suspecting mi. many studies have been conducted to predict the occlusion site by interpreting the st segment deviations in electrocardiogram (ecg).additional posterior and right precordi...
over a period of four years, we followed 200 male cases (female patients were excluded from this study because from early childhood, the majority of iranian girls have their ears pierced which tends to distort the ear lobe and renders the diagnosis of the crease difficult) of proved coronary artery disease (angina pectoris, coronary insufficiency, and myocardial infarction) in a private clinic ...
background: according to the angiographic findings, 3%-8% of atherosclerotic coronary artery patients suffer from coronary artery ectasia (cae). we conducted this study to estimate the prevalence of cae among patients who underwent angiography and compared this group with those patients without cae and atherosclerosis in terms of common coronary heart disease (chd) risk factors. methods : this ...
case presentation we present a case of a grade iii coronary perforation in which the double guiding catheter technique helped us to deliver the graft stent. conclusions the double-guiding technique is useful in emergency situations to increase the safety and efficacy of sealing a coronary perforation. introduction coronary vessel perforation is one of the most feared complications of coronary a...
triggering of acute myocardial infarction m. salehian [1] abstract coronary heart disease (chd) is the leading cause of death in the united states each year about 450.000 people die from chd, and 1.000.000 experience an initial or recurrent coronary event. plaque rupture and it's its subsequent thrombosis at the site of the plaque rupture is the most common underlying pathophysio...
