Background: Left main coronary artery (LMCA) stenosis is a leading cause of mortality and morbidity in many countries. Metabolic syndrome (MS) is a risk factor for coronary artery disease (CAD). The effects of MS on left main coronary artery stenosis are not well-defined. The aim of this study was to examine the effects of MS on left main coronary artery stenosis.Methods: A total number of 495 ...
background: the incidence of stroke after coronary artery bypass grafting (cabg) is between 0.9% and 6.7%, which significantly increases in-hospital and out-hospital costs. this study was designed to evaluate the prevalence of significant carotid stenosis and its risk factors in cabg. methods: in total, 2044 consecutive patients undergoing elective cabg were investigated through a pre-operative...
Introduction: Renal artery stenosis is the most prevalent disease of renal artery and has an important role in making hypertension and renal atrophy. Since in previous researches, despite high frequency of risk of cardiovascular disease in Iran, there did not exist any general research investigating risk factors of coronary artery disease and incidence of contemporary renal artery stenisis, ...
successful implantation of coronary sinus lead after balloon angioplasty of a coronary vein stenosis
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.
background: early clinical and retrospective angiographic evaluations indicated that in patients with acute myocardial infarction (mi), vulnerable plaques most often represented a mild luminal stenosis. more recent studies drawing upon prospective angiograms, however, have demonstrated that in majority of patients with acute mi, the underlying stenosis is significant. methods: twenty-eight pa...
conclusions the coronary sinus flow per minute is the most accurate parameter among the three echocardiographic parameters mentioned above for the assessment of significant stenosis of the coronary artery. results flow (ml/minute), flow/lvm (ml/minuteg) and lv (d-s) mass a-l all correlated significantly with the percentage of stenosis (r = -0.64, p < 0.001; r = -0.47, p < 0.001; r = -0.56, p < ...
conclusions presence of cae in patients with cas increases its cardiovascular event rate. isolated cae is not a benign finding and mi can occur. risk factors of cae are similar to cas, but c/s is more associated with cae than cas. dm is seen in cae patients less than cas. results hypertension (htn), dyslipidemia (dlp), and male sex were matched in both groups without significant difference. cig...
conclusion we conclude that coronary calcium scoring provided useful information in the management of patients. in cacs less than 100, it has a npv of 87% in excluding significant stenosis in patients with the risk of cad but it does not have enough diagnostic accuracy for surely excluding coronary stenosis, so we should perform a combination of cacs and coronary ct angiography for patients. re...
background: coronary disease is the most common cause of death in the world. because of common risk factors, atherosclerotic stenosis of coronary and carotid arteries occurs together. this study evaluated the prevalence of carotid stenosis in diabetic candidates for angiography methods: in a cross-sectional study, 152 diabetic candidates for angiography referred to cardiology clinic of shariati...
Abstract Background: Recently, small dense low density lipoprotein (sdLDL) has been highlighted as a new risk factor for the coronary artery disease (CAD).Small dense LDLs 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 low density lipoprotein (LDL) receptor and increased affinity...
