BACKGROUND Atherosclerosis is the commonest cause of vascular disease which can involve peripheral and/or cardiac vessels. This study was conducted to evaluate the possible link between Ankle-Brachial Index (ABI) and coronary vessel involvement in patients with stable angina. METHODS This cross-sectional study was conducted in 2008 on 120 individuals who were hospitalized in Chamran Heart Cen...

Residual self-interference (SI) cancellation in the digital baseband is an important problem in full-duplex (FD) communication systems. In this paper, we propose a new technique for estimating the SI and communication channels in a FD communication system, which is inspired from superimposed signalling. In our proposed technique, we add a constant real number to each constellation point of a co...

OBJECTIVE This study assessed the relative risk factors for osteoporosis in women referring to the Bone Densitometry Center during 2007, with the aim of designing a formula to estimate the severity of osteoporosis. SUBJECTS AND METHODS Data of outpatients (n = 1,047) who visited the Bone Densitometry Center of Chamran Hospital were gathered by administering a questionnaire to subjects before ...

BACKGROUND Today, ischemic heart diseases (IHDs) are the most common diseases worldwide. Angiography is the best way to diagnose IHDs. Angiographic complications however can include death, myocardial infarction, nausea, spasm of the coronary arteries, chest pain, bradyarrhythmia, hypotension, or hypertension. This study aimed to determine the effects of a simultaneous injection of trinitroglyce...

BACKGROUND Coronary artery disease is a leading cause of death in developed countries. On the other hand, increased level of CRP has been seen in atherosclerosis. According to this finding, we decided to conduct this study to assess the relationship between CRP and complex lesions of coronary arteries in patients with unstable angina. METHODS In this analytical cross sectional study which was...

BACKGROUND Cardiovascular events are common in patients with diabetes mellitus (DM), which make coronary artery bypass graft (CABG) a highly demanded surgery in this population. Tight control of blood glucose in patients with DM is beneficial in reducing postoperative complications; however, the adequate range has not been determined yet. OBJECTIVES This study aimed to investigate the effect ...

BACKGROUND Iron is essential for many physiological processes; whereas, iron overload has been known as a risk factor in progression of atherosclerosis. The aim of this study was to investigate the importance of serum ferritin levels, which are known as an indicator of body iron stored in the incidence of coronary artery disease (CAD). METHODS In a case-control study, we evaluated 432 eligibl...

BACKGROUND There is a lack of data in our society on the outcomes, complications, and prognostic factors in patients with coronary artery disease who underwent percutaneous coronary intervention (PCI). We evaluated the success rate, early and late outcomes, and prognostic factors in a referral university center in Isfahan, IRAN. METHODS This prospective cohort study was conducted in Chamran U...

BACKGROUND No-reflow phenomenon after percutaneous coronary intervention (PCI) in patients with acute ST-segment-elevation myocardial infarction (STEMI) is relatively common and has therapeutic and prognostic implications. Cigarette smoking is known as deleterious in patients with coronary artery disease (CAD), but the effect of smoking on no-reflow phenomenon is less investigated. The aim of t...
