Background There are some data showing that repurposed drugs used for the Coronavirus disease-19 (COVID-19) have potential to increase risk of QTc prolongation and torsade de pointes (TdP), these arrhythmic side effects not been adequately addressed in COVID-19 patients treated with medications. Methods This is prospective study 2403 hospitalised at 13 hospitals within epicentres Iran. These were chloroquine, hydroxychloroquine, lopinavir/ritonavir, atazanavir/ritonavir, oseltamivir,...
The novel coronavirus spread all over the world in 2019 and became a serious international health concern of this century. Coronavirus disease (COVID-19) had wide range clinical manifestations; it can cause mild-to-severe multiorgan diseases, mostly affecting respiratory system, but cardiovascular symptoms complications are also frequently presented COVID-19 patients. Herein, we report type A aortic dissection confirmed case COVID-19.
Obstruction of the access vein following cardiac pacemaker and defibrillator implantation is a common complication. However, exact incidence contributing risk factors are unknown. The aim this study to determine analyze contribution each factor.57 consecutive patients candidate for their first transvenous pacemaker, implantable cardioverter-defibrillator (ICD), or resynchronization therapy device were enrolled. After implantation, venography ipsilateral peripheral arm was performed. Patients...
Background & objectives: cardiovascular diseases are the main cause of mortality around whole world.However, there is limited information on its economic costs in Iran.The aim this study was to evaluate coronary heart disease Iran 2014.Methods: The were calculated based incidence approach using a bottomup method and community-oriented perspective.The drug cost obtained from angiographed patients (607 cases) Shahid Modarres Hospital simple random sampling method.Other like incidence,...
In this paper, we develop a low-cost cellular internet of medical things (IoMT)-based electrocardiogram (ECG) recorder for monitoring heart conditions and used in practical cases. order to remove noise from signals recorded by these non-clinical devices, propose cloud-based denoising approach that focuses on utilizing deep neural network techniques the time-frequency domain through two stages. Accordingly, exploit fractional Stockwell transform (FrST) transfer ECG signal into apply robust...
Abstract Background . Recent studies have confirmed the essential and paramount role of L-Citrulline on nitric oxide regulation endothelial function improvement. Materials Methods In this cross-over clinical trial, thirty patients, diagnosed with coronary artery disease (CAD) flow mediated dilation to nitroglycerin dependent vasodilation (FMD/NMD) ratio less than 1, were included. The patients randomly divided into two groups 15 underwent treatment by or placebo for days, in 2 step protocol....
Abstract Background Implantable cardioverter‐defibrillator (ICD) is the most effective therapy currently available to prevent sudden cardiac death (SCD) in patients with left ventricular (LV) dysfunction. Although LV ejection fraction (LVEF) an excellent marker of SCD these patients, determining other predictors might help identify who will be benefit more from device implantation. The purpose this study was determine whether abnormal sphericity index (SI) transthoracic echocardiography...
We report on a 45-year-old female who developed cardiomyopathy due to incessant dual atrioventricular nodal nonreentrant tachycardia. Her condition was completely resolved by performing radiofrequency ablation of the slow pathway.
Brugada Syndrome is a cardiac ion channel disorder that affects the sodium current. This syndrome characterized by cove-shaped ST elevation in ECG leads V1 to V3 absence of structural heart disease.A 36-year-old man diagnosed with was reffered our center frequent implantable cardioverter-defibrillator (ICD) discharges. ICD interrogation showed several appropriate intervention for tachycardia detected ventricular fibrillation zone. Unfortunately, quinidine not available country at time...
Previous studies evaluated the impact of particle matters (PM) on risk acute myocardial infarction (AMI) based local registries.This study aimed to evaluate possible short term effect air pollutants occurrence AMI a specific case report sheet that was designed for this purpose.AMI documented among 982 patients who referred emergency departments in Tehran, Iran, between July 2017 March 2019. For each patient, period defined as 24 hour preceding time admission and referent periods were...
Introduction: Prognosis of the patients with beta blocker or calcium channel induced AV block is not well known to date.Methods: All symptomatic second-degree third-degree atrioventricular (AV) referred our institution during one year were recuited prospectively and classified in two groups based on drug consumption (beta blocker/calcium versus none). They followed for six months then collected data was analyzed.Results: The study included 49 patients, 28 (age 60.1 ± 20, 19 male) did use any...
The use of vagal nerve stimulation is identified as a proper treatment option in patients with stable supraventricular tachycardia (SVT). This study aimed to assess the success Valsalva maneuver via handmade device reversion SVT.In this quasi experimental study, using device, vagus was performed for SVT presenting emergency department or cardiac intervention unit and rate its related factors were assessed.100 mean age 53.05 ± 13.70 years studied (67% female). 12 (12%) cases unable do...
<br><b>Background:</b> Several complications can occur during electrophysiology (EP) study and radiofrequency catheter ablation (RFCA). In this study, we aimed to determine the frequency types of following EP RF in a tertiary cardiovascular center. <b>Methods:</b> Between September 2012 December 2012, patients undergoing studies were prospectively enrolled. Demographic clinical data patients, as well underlying arrhythmia indication for recorded. Complications occurring procedure admission...
Background: Differentiating ischemic from nonischemic cardiomyopathy is important both prognostically and therapeutically, although it may be difficult clinically. Objectives: We aimed to determine the diagnostic power of Cardiogoniometry (CGM) in differentiation etiology left bundle branch block (LBBB). Patients Methods: studied 37 patients with LBBB on electrocardiogram (ECG) ventricular ejection fraction (LVEF) < 30%. All them underwent coronary angiography, 33 were included. Eighteen...
