Objective: This study aimed to evaluate the predictors and clinical outcomes of coronary artery ectasia (CAE) in patients presenting with acute coronary syndromes (ACS). Methods: Study included patients diagnosed with CAE who presented wit…
Efficacy and safety of combination therapy Ezetimibe 10/rosuvastatin 40 in Egyptian patients at very high risk of atherosclerotic cardiovascular disease Open
Background Lipid-lowering therapies (LLT) are well-established in reducing cardiovascular complications and improving outcomes in patients with atherosclerotic cardiovascular disease (ASCVD). However, the efficacy of LLT varies across diff…
Tips for preventing hematoma and infection after pacemaker implantation Open
Background: The purpose of the study was to identify the clinical factors associated with hematoma formation after PM or ICD device implantation and how to prevent it. Methods: Fifty patients (group 1) were subjected to local measures such…
Impact of left ventricular hypertrophy on frequency and complexity of ventricular arrhythmia among hypertensive Egyptian patients Open
Background Left ventricular hypertrophy (LVH) is associated with an increased risk of ventricular arrhythmias and cardiovascular mortality. The study objective was to investigate the effect of LVH severity on the complexity and severity of…
Stenting the unprotected left main coronary artery- mid-term outcomes of the observational registry Open
Background: The results of stenting the unprotected left main coronary artery (UPLM) without IVUS but with meticulous care need to be studied more.Methods: This prospective and retrospective study was performed in multiple local centers.Th…
Stenting the unprotected left main coronary artery- mid-term outcomes of the observational registry Open
Background New imaging modalities such as IVUS had improved results of Stenting of the unprotected left main coronary artery (UPLM). The results of stenting UPLM without these new modalities but with meticulous care need to be studied more…
Correlation between the incidence and severity of Aortic Valve Calcific Stenosis and Carotid Atherosclerosis Open
ABSTRACT Background: Aortic valvular calcification (AVC) and carotid arterial disease (CaAD) have a high prevalence in elderly patients (pts). Aim of the work: To study the severity and relation of carotid plaques and coronary atherosclero…
Smoking is a more dangerous risk factor than metabolic syndrome in Egyptian patients with Acute Myocardial Infarction Open
ABSTRACT Background: The effect of metabolic syndrome and other risk factors of myocardial infarction are not consistent in all studies. Aim: To assess the incidence of each risk factor in our community as a predictor of acute myocardial i…
Right ventricular pacing is not harmful as perceived previously Open
Background: Pacing from the apex of the RV is not optimal. This study aimed to assess and compare RV and LV pacing of LV function and dyssynchrony. Thirty-six patients who presented with indications for pacemakers were studied. We divided …
Study of electrocardiogram in competitive athletes Open
ABSTRACT Background: Sudden death in athletes is a major concern; the predictors and value of prior investigations remain to be settled. The work aims at studying electrocardiograms (ECG) in competitive athletes to define incidence of abn…
Stenting the unprotected left main coronary artery without invasive imaging techniques Open
Background New imaging modalities such as IVUS had improved results of stenting of the unprotected left main coronary artery (UPLM). The results of stenting UPLM without these new modalities but with meticulous care need to be studied more…
Comparative study of the effect of left ventricular pacing versus right ventricular pacing on left ventricular function Open
Background : Pacing from the apex of the RV is not considered optimal. This work aimed to assess and compare RV and LV pacing concerning LV function and dyssynchrony. Thirty-six patients who presented with indications for pacemakers were d…
Innovations in Electrophysiology Technologies and Devices Open
There are major advances and achievements in devices used in electrophysiology diagnosis and treatment.This short summary is collection of recent publications around this subject.

Background: Pacing from the apex of the RV is not considered optimal. This work aimed to assess and compare RV and LV pacing concerning LV function and dyssynchrony.Thirty-six patients who presented with indications for pacemakers were div…
Study of Bradyarrhythmias in Acute Myocardial Infarction Open
Background: Arrhythmias after acute myocardial infarction are common. Bradyarrhythmias need specific insight into when and how to treat them. Objectives: To delineate the incidence, course, and management of different types of bradyarrhyth…

Aims The aim of the Familial Hypercholesterolemia Research Collaboration (FHRC) is to collect date about the clinical, laboratory phenotypes, and treatment strategies of patients with FH all over the world. We present the Egyptian data of …
Upgrading Patients with Pacemakers to Resynchronization Pacing: Predictors of Success Open
The investigations of predictors of success or failure of cardiac resynchronization therapy (CRT) were studied previously. But assessment of success in patients already on dual or single pacemakers and upgraded to CRT were not extensively …
Smoking is a more dangerous risk factor than metabolic syndrome in Egyptian patients with acute myocardial infarction Open
The aim of the manuscript is to assess the incidence of each risk factor in our community as a predictor of acute myocardial infarction. Fifty patients (Pts) admitted to the main university hospital with acute MI were studied. Inclusion cr…
