Material And Methods: Fifty-one patients with HCM (51% female, mean age = 21 ± 5.

Endothelial nitric oxide synthase Asp298Glu (894G/T) gene polymorphism as a possible risk factor for the coronary slow flow phenomenon among Iranians.

Background: Mounting evidence indicates an association between endothelial dysfunction and the coronary slow flow phenomenon (CSFP). In the present study, we aimed to evaluate the possible role of endothelial nitric oxide synthase (eNOS) 894G/T and interleukin-1β (IL-1β) 315C/T polymorphisms as possible risk factors for CSFP.

Methods: This prospective study enrolled patients with CSFP and individuals with normal coronary arteries.

Cardiac Reverse Remodeling After Transcatheter Patent Ductus Arteriosus Closure in Adults.

Whereas most patent ductus arteriosus (PDAs) are identified and treated in the childhood, and the long term outcome studies have approved the outstanding results (positive cardiac reverse remodeling) in these group of patients, the outcome of percutaneous PDA closure in adults is not comprehensible. The aim of this retrospective cohort study which consecutively recruited 121 adult patients (age >16 years) who underwent the transcatheter closure (TCC) of PDAs between 2012 and 2018 is, evaluation at least 1-year follow-up of adult patients after PDA closure and compare the hemodynamic and the cardiac reverse remodeling findings with the previous studies in adults and children.

Percutaneous Balloon Pulmonary Valvuloplasty of Critical Pulmonary Stenosis and severe pulmonary stenosis in Neonates and Early Infancy: A Challenge in the Cyanotic.

Pulmonary stenosis with an intact ventricular septum (PS-IVS) is one of the common causes of cyanotic heart disease in neonates with diverse morphologies as well as management and treatment protocols. The aim of this study was to evaluate short and midterm results of balloon pulmonary valvuloplasty (BPV) for this disorder. Between 2012 and 2016, Totally 45 neonates and infants under 6 months old were evaluated.

Warning signals of elevated prediabetes prevalence in the modern Iranian urban population.

Background: We sought to estimate the prevalence of diabetes mellitus (DM) and pre-DM and their associated factors among a sample of the Iranian urban population between 2017 and 2019.

Methods: The present investigation is a sub-study on the HAMRAH cohort study, a longitudinal population-based cohort study to assess the 10-year risk of cardiovascular diseases and their related risk factors in the adult population of the Iranian capital, Tehran. Via a multistage cluster randomized sampling method, 2123 adults aged between 30 and 75 years who had no history of cardiovascular diseases were selected for the study.

Is there any association between contrast-induced nephropathy and serum uric acid levels?

During the recent years, several studies have investigated that hyperuricemia is associated with greater incidence of contrast induced nephropathy (CIN). Most of them are in acute conditions like primary percutaneous coronary interventions. This study aimed to assess the relationship between high serum uric acid and incidence of acute kidney injury in patients undergoing elective angiography and angioplasty.

Intravascular Ultrasound for Assessment of Residual Coarctation of the Aorta after Balloon Angioplasty in Infants.

Intravascular ultrasound (IVUS) has been introduced as an accurate and minimally invasive diagnostic technique for the assessment of vascular anatomy and its abnormalities. We believe that IVUS can be used for clarifying the reasons for failure of balloon angiography in infantile coarctation of the aorta (CoA), because post-balloon angioplasty tearing, intimal flap, thrombosis and pseudoaneurysm of the aorta can be evaluated by IVUS with greater sensitivity and specificity. We aimed to assess the outcome of balloon angioplasty of CoA using angiography as the gold standard and IVUS as a new method in infants, comparing the two techniques for the evaluation of the diameter and area of CoA segment pre- and post-procedure.

The Relationship Between Spiritual Health and Quality of Life of Heart Transplant Candidates.
