INTRODUCTION The mediastinitis is a serious postoperative complication of cardiac surgery, with an incidence of 0.4 to 5% and mortality between 14 and 47%. Several models were proposed to assess risk of mediastinitis after cardiac surgery. However, most of these models do not evaluate the postoperative morbidity. OBJECTIVE This study aims to develop a score risk model to predict the risk of m...

coronary artery bypass grafting (cabg) surgery is being performed increasingly in iran. so far, no large-scale report has described characteristics and risk factor profile and in-hospital mortality of patients undergoing this procedure in iran. we conducted this study to address these topics in order to help clarify iran's current state of cabg and to provide assistance in planning combat again...

INTRODUCTION The most widely used model for predicting mortality in cardiac surgery was recently remodeled, but the doubts regarding its methodology and development have been reported. OBJECTIVE The aim of this study was to assess the performance of the EuroSCORE II to predict mortality in patients undergoing coronary artery bypass grafts or valve surgery at our institution. METHODS One tho...

abstract nowadays, coronary artery bypass grafting (cabg) is considered to be one of the most common surgical procedures. this procedure has been the main topic in many clinical research studies, which have assessed the effect of the procedure on patients’ outcomes. like other surgical procedures, this procedure is also accompanied by a number of unwanted complications, including those of the r...

OBJECTIVE The aim of this study is to establish a cut-off value for troponin I by correlating it to occurrence of postoperative myocardial infarction. METHODS 180 consecutive patients with coronary disease referred for surgery were included. The mean age of the patients were 60.6 (+/-9.3) years, with 119 (66.1%) males and 61 (33.9%) females. The patients were divided into two groups: group wi...

background: given the lack of consistency in the literature regarding the reliability of the ankle-brachial index (abi) as a valid screening tool and an independent risk indicator of cardiovascular events and mortality, we compared it with angiography as a reference standard test. methods: this case-control study, conducted between 2010 and 2011 in tehran heart center, recruited 362 angiographi...

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 < ...
