Background: Distal Radial Artery (DRA) is a new arterial access for coronary catheterization. Assessment of the vascular complications of this new procedure is important in the provision of nursing care to cardiac patients. The aim of this study was the nursing assessment of vascular complications of DRA in angiography and angioplasty.

World Health Organization has designated coronavirus disease 2019 (COVID-19) as a pandemic. During the past several weeks, a considerable burden has been imposed on the Iranian's healthcare system. The present document reviewed the latest evidence and expert opinion regarding the management of ST-segment-elevation myocardial infarction during the outbreak of COVID-19 and outlines a practical algorithm for it.

Objectives: The regenerative potential of bone marrow-derived mononuclear cells (MNCs) and CD133+ stem cells in the heart varies in terms of their pro-angiogenic effects. This phase II/III, multicenter and double-blind trial is designed to compare the functional effects of intramyocardial autologous transplantation of both cell types and placebo in patients with recent myocardial infarction (RMI) post-coronary artery bypass graft.
Materials And Methods: This was a phase II/III, randomized, double-blind, placebo-controlled trial COMPARE CPM-RMI (CD133, Placebo, MNCs - recent myocardial infarction) conducted in accordance with the Declaration of Helsinki that assessed the safety and efficacy of CD133 and MNCs compared to placebo in patients with RMI.
Traditionally, the degree of luminal obstruction has been used to assess the vulnerability of atherosclerotic plaques. However, recent studies have revealed that other factors such as plaque morphology, material properties of lesion components and blood pressure may contribute to the fracture of atherosclerotic plaques. The aim of this study was to investigate the mechanism of fracture of atherosclerotic plaques based on the mechanical stress distribution and fatigue analysis by means of numerical simulation.

Objectives: Therefore, we evaluated the most used and suggested protocol for treating Vitamin D deficiency in Percutaneous coronary intervention (PCI) candidate patients referred to our hospital in a short-term clinical trial.
Background: Diabetes mellitus (DM) is a very well-known risk factor for development of atherosclerosis, and it has been hypothesized that poor glycemic control and hyperglycemia plays a major role in this process. In the current study, we aimed to evaluate the associates of poor glycemic control in Iranian patients who have already undergone coronary artery bypass grafting (CABG), with especial focus on the inhabitation of infectious agents within the coronary arterial wall.
Methods: In January 2010, 52 consecutive patients with type 2 DM who undergone CABG at the Department of Cardiovascular Surgery of Baqiyatallah University of Medical Sciences (Tehran, Iran) were included into this cross-sectional study and biopsy specimens from their coronary plaques were taken and analyzed by polymerase chain reaction (PCR) methods for detecting Helicobacter species, cytomegalovirus (CMV) and Chlamydia pneumoniae, and their potential relation to the glycemic control status in these patients.
An association between Chlamydia pneumoniae (C. pneumoniae) and cardiovascular disease has been demonstrated. In this study, we aimed to study this potential relationship in 105 Iranian patients.

Methods: Blood flow through aortic valve was measured by Doppler flow echocardiography. Aortic valve geometry was calculated by echocardiographic imaging.
It has been shown that cytomegalovirus (CMV) is present in coronary atherosclerotic plaques, but the clinical relevance of this presence remains to be elucidated. In this study we sought to examine CMV infection in atherosclerosis patients defined by different methods and to identify the clinical significance of CMV replication in the atherosclerotic plaques. The study included 105 consecutive patients who were admitted to our department and underwent coronary artery bypass grafting (CABG) surgical interventions.

In the current study, we aimed to evaluate the prevalence and relevance of H. pylori infection, using polymerase chain reaction (PCR) methods, in the coronary arterial wall of Iranian patients who have already undergone coronary bypass grafting (CABG).

Methods And Results: We retrospectively surveyed our hospital carotid stenting data base, to identify all patients who were scheduled to undergo staged carotid stenting followed by CABG. A total of 39 patients who underwent CAS were candidates for staged CABG but only 28 (71.
Background: Carotid artery stenting has recently been recommended as an alternative to carotid endarterectomy by some clinicians.
Objective: To evaluate success rate, as well as in-hospital and 30-day adverse events in our first experience in Iran for carotid artery stenting with protection devices.
Methods: From December 2003 through July 2004, we performed 12 consecutive (9 males and 3 females) carotid artery stenting procedures.
Background/objective: In patients with severe concurrent coronary and carotid artery disease, two different treatment strategies may be used: simultaneous endarterectomy and coronary bypass surgery, and carotid stenting with delayed coronary bypass surgery after a few weeks. To evaluate the safety and efficacy of carotid stenting with delayed coronary bypass surgery after a few weeks in patients referred to Tehran Heart Center, Tehran, Iran and to determine the independent predictors that may be used to identify the appropriate treatment plan for such patients.
Methods: This prospective study was performed from December 2003 through October 2004.
