Correlation between coronary artery calcification and COVID-19.

Background: Coronary heart disease (CHD) is an underlying cardiac condition contributing to increased COVID-19 mortality and morbidity which can be assessed by several diagnosis methods including coronary artery calcification (CAC). The goal of this study was to find out if there were potential links between CAC, clinical findings, severity of COVID-19, and in-hospital outcomes.

Methods: This retrospective study evaluated 551 suspected patients admitted to teaching hospitals of the Babol University of Medical Sciences, Babol, Iran, from March to October 2021.

Electrocardiographic parameters and mortality in patients with SARS-CoV-2 infection: A single center study.

Background: Coronavirus disease 2019 (COVID-19) is a pandemic outbreak of RNA coronaviruses (SARS-CoV-2), associated with acute respiratory distress syndrome, multiple organ failure, and death. The surface electrocardiogram is the first line assessment of cardiac electrical system. We aimed to interpret classically the electrocardiographic parameters at admission and during hospital course and association of them with prognosis in patients admitted with diagnosis of infection with SARS-CoV-2.

Coronary artery calcification score as a prognostic indicator for COVID-19 mortality: evidence from a retrospective cohort study in Iran.

Background: Coronary artery calcification (CAC) has been established as an independent risk factor for major adverse cardiovascular events. Nevertheless, the effect of CAC on in-hospital mortality and adverse clinical outcomes in patients with COVID-19 has yet to be determined.

Objective: To investigate the association between CAC score and in-hospital mortality of COVID-19 patients.

Methods: This online program was conducted in three days. The main content of the class was taught during one hour, and after that, the teacher spent enough time for responding the asked questions.

Complications of Implantable Cardioverter Defibrillator and Their Potential Risk Factors in Patients with Hypertrophic Cardiomyopathy.

Background: Hypertrophic cardiomyopathy (HCM) has different complications such as cardiac arrhythmia and sudden cardiac death (SCD). Insertion of an implantable cardioverter defibrillator (ICD) is recommended for HCM patients who are at high risk of SCD and malignant arrhythmias, despite having their own potential complications. .

Novel SCN5A variants identified in a group of Iranian Brugada syndrome patients.

Brugada syndrome (BrS) is a rare hereditary arrhythmia syndrome that increases an individual's risk for sudden cardiac death (SCD) due to ventricular fibrillation. This disorder is regarded as a notable cause of death in individuals aged less than 40 years, responsible for up to 40% of sudden deaths in cases without structural heart disease, and is reported to be an endemic in Asian countries. Mutations in SCN5A are found in approximately 30% of patients with Brugada syndrome.

Interleukin 10, lipid profile, vitamin D, selenium, metabolic syndrome, and serum antioxidant capacity in elderly people with and without cardiovascular disease: Amirkola health and ageing project cohort-based study.

Background: The age-related autoinflammation-mediated atherosclerosis is associated with some immunological, nutritional, and metabolic parameters and redox status. Here, we evaluated the association of circulatory interleukin 10 (IL-10) levels with lipid profile, some nutrients, and total anti-oxidant capacity in elderly people who presented cardiovascular disease (CVD) with or without metabolic syndrome (MetS) and in healthy subjects.

Methods: In this cross-sectional case-control study, 258 sera prepared from elderly people (144 healthy and 114 patient subjects) who participated in a community-based study, the Amirkola Health and Ageing Project (AHAP), were analyzed for IL-10, lipid profile, vitamin D, selenium (Se), antioxidant capacity, and MetS.

Association of vitamin D deficiency and premature coronary artery disease.

Background: Evidence suggests hypovitaminosis D is associated with increased risk of coronary artery disease (CAD) and its extent and related risk factors. However, some investigations have produced contrary results. Therefore, we aimed to evaluate the association between serum vitamin D levels and the severity of premature coronary artery involvement.

Implantable cardioverter-defibrillator in a patient with dextrocardia situs inversus.

Background: Dextrocardia is a congenital anomaly, which may have coexistent coronary artery disease (CAD), arrhythmias and conventional indications for device therapy. However, the implantation of transvenous leads can be technically challenging and the approach needs to be tailored to the patient's individual anatomy.

Case Presentation: A 54-year-old male with dextrocardia situs inversus and ischemic left ventricular dysfunction developed ventricular tachycardia and fibrillation.

Pericardial Graft vs. Host Disease in a Patient with β-Thalassemia Major.

Bone marrow transplantation (BMT) in young children improves results in β-thalassemia major. Graft versus host disease (GVHD) is an important complication of peripheral blood stem cell transplantation. GVHD affects heart with a behavior resembling an autoimmune disease, including pericardial effusion.

Etiology of syncope in hospitalized patients.

Background: Syncope is a common clinical problem which can be remarkably debilitating and associated with high health care costs. Syncope is a clinical syndrome with many potential causes. The aim of the study was to determine the etiologies of patients with syncope in the emergency department (ED) of a referral and general university hospital.

Aortic dissection and postpartum cardiomyopathy in a postpartum young woman: a case report study.

Introduction: Aortic dissection is a rare condition in young women and usually related with congenital anomalies of aorta and connective tissue disorders. We reported a 34-year-old postpartum woman with aortic dissection.

Case Presentation: The patient complained of respiratory distress and weakness with no abdominal pain or chest pain 20 days after delivery and had no history of hypertension during pregnancy and perinatal or prior heart disease.

Evaluation of tissue doppler echocardiography and T2* magnetic resonance imaging in iron load of patients with thalassemia major.

Background: Iron-mediated cardiomyopathy is the main complication of thalassemia major (TM) patients. Therefore, there is an important clinical need in the early diagnosis and risk stratification of patients. The aim of this study was to evaluate the efficacy of tissue doppler imaging (TDI) to study cardiac iron overload in patients with TM using T2* magnetic resonance (MR) as the gold-standard non-invasive diagnostic test.
