background: obstructive sleep apnea (osa) is very frequent and often unrecognized in surgical patients. osa is associated with perioperative complications. we evaluated the effects of osa on postoperative complications and hospital outcomes in patients undergoing coronary artery bypass graft (cabg) surgery. methods: candidates of elective cabg were evaluated by the berlin questionnaire for osa....

INTRODUCTION Coronary artery bypass grafting is a safe procedure performed worldwide with low rates of mortality and morbidity in general population. OBJECTIVE To investigate risk factors for mortality of patients undergoing coronary artery bypass grafting coronary artery bypass grafting surgery. METHODS A total of 1,628 consecutive patients undergoing on-pump coronary artery bypass graftin...

BACKGROUND Current study addressed the predictive value of 12-lead electrocardiogram (ECG) in patients with suspected coronary artery disease (CAD). METHODS Four hundred consecutive patients with new onset of chest pain were studied. A resting standard 12-lead ECG was recorded and all patients underwent coronary angiography. RESULTS ECG correctly detected significant stenosis in 176 out of ...

OBJECTIVES This study evaluated whether coronary artery calcium scores (CACS) and the degree of stenosis that were measured with computed tomography coronary angiography (CTCA) predicted post-operative cardiovascular events in patients who were undergoing intermediate-risk noncardiac surgery. BACKGROUND Cardiovascular complications are important causes of mortality and morbidity in patients u...

a t t c t Background. Coronary artery endarterectomy with cornary artery bypass grafting for diffuse coronary artery isease has been associated with increased morbidity nd mortality. We evaluated our institutional experience o redefine the role of coronary endarterectomy for difuse coronary artery disease. Methods. From 1985 to 2002 isolated coronary artery ndarterectomy with coronary artery by...

BACKGROUND Insulin-resistance is associated with cardiovascular disease but it is not used as a marker for disease in clinical practice. AIMS To study the association between the homeostatic model assessment (HOMA-IR) and triglyceride/HDLc ratio (TG/HDLc) with the presence of coronary artery disease in patients submitted to cardiac catheterization. METHODS In a cross-sectional study, 131 pa...

The instantaneous wave-free ratio (iFR) closely related to fractional flow reserve (FFR) is a adenosine-independent physiologic index of coronary stenosis severity. We sought to evaluate whether iFR derived from coronary computed tomographic angiography (iFRCT) can be used as a novel noninvasive method for diagnosis of ischemia-causing coronary stenosis.We retrospectively enrolled 33 patients (...

BACKGROUND Interleukin-6 (IL-6) plays a central role in atherosclerosis and inflammation. It may improve risk prediction in patients at intermediate cardiovascular risk. OBJECTIVE To analyze the impact of serum IL-6 in predicting early angiographic coronary artery disease in patients at intermediate cardiovascular risk with chest pain. METHODS In a cross-sectional study, patients referred f...

conclusions the findings showed a positive effect of therapeutic relationship based on peplau's model on reducing anxiety of patients undergoing cabg. therefore, health care teams, including nurses, should take advantage of appropriate communication with patients in their care procedures. in that regard, peplau's communication model is recommended as a simple, low-cost, and efficient method. re...
