Hospital Readmission Through the Emergency Department.

Background: Hospital readmission places a high burden on both health care systems and patients. Most readmissions are thought to be related to the quality of the health care system.

Objectives: The aim of this study was to examine the causes and rates of early readmission in emergency department in a Tehran hospital.

Atorvastatin therapy is not associated with slowing the progression of aortic stenosis: findings of a randomized controlled trial.

Background: Aortic stenosis (AS) is the most common type of valvular cardiac disorders. AS has many risk factors in common with atherosclerosis. Hypercholesterolemia is an important pathomechanism for AS.

Impact of cardiac rehabilitation on metabolic syndrome in Iranian patients with coronary heart disease: the role of obesity.

Background: Due to high prevalence of metabolic syndrome (MetS) and coronary heart disease (CHD) in Iran, and their mutual relationship, we evaluated how comprehensive cardiac rehabilitation (CR) can affect MetS in patients with CHD.

Method: In this study (1998-2003), we evaluated 547 patients with CHD undergoing comprehensive CR.

Results: Cases with MetS decreased from 42.

Coincidence of free-floating thrombus in the aortic arch, severe mitral stenosis, and left atrial appendage clot.

We describe the surgical management of a free-floating thrombus in the aortic arch in a patient with severe mitral stenosis, a left atrial appendage (LAA) clot, and an iliac artery thrombus. A 60-year-old woman complaining of dyspnea and pain in her right leg was referred to our multidisciplinary clinic. After a brief history was taken, an electrocardiography evaluation showed atrial fibrillation.

Gender differences in risk factors and outcomes after cardiac rehabilitation.

Objective: We compared the baseline characteristics, cardiovascular risk factors and outcomes between men and women in an Iranian cardiac rehabilitation programme after adjusting for age, body mass index and waist-to-hip ratio.

Methods: In a self-controlled descriptive study performed between 1996 and 2006, we evaluated 547 patients with documented coronary heart disease before and after a 24-session cardiac rehabilitation programme.

Results: Women were older, more likely to be obese, anxious, depressed, and had more traditional coronary heart disease risk factors than men.

Knowledge, attitude, and practice of Iranian surgeons about blood-borne diseases.

Background: Perhaps more than any other healthcare worker, it is the surgeons who are at an increased risk of exposure to hepatitis B (HB) virus, hepatitis C virus, and human immunodeficiency virus. The aim of this study was to evaluate surgeons' concerns regarding risk awareness and behavioral methods of protection against blood-borne pathogen transmission during surgery.

Materials And Methods: A 31-item questionnaire with a reliability coefficient of 0.

A very rare case of single coronary artery anomaly, with left anterior descending and left circumflex arteries originating separately from proximal right coronary artery.

Coronary artery anomalies are rare, with the reported prevalence of 0.2% to 1% in routine angiographic studies. Among them, presence of a single coronary artery is one of the rarest anomalies, comprising less than 3% of all coronary anomalies.
