Effect of intravenous atropine on treadmill stress test results in patients with poor exercise capacity or chronotropic incompetence
Objective: Exercise stress test (EST) is one of the main diagnostic and prognostic tests for ischemic heart disease. However, its usefulness depends on achieving target heart rate, then chronotropic incompetence and poor ...
Comparison between covered and bare Cheatham-platinum stents for endovascular treatment of patients with native post-ductal aortic coarctation: Immediate and intermediate-term results
Objectives: This study sought to evaluate the outcomes of endovascular treatment with covered versus bare Cheatham-platinum stents (NuMed, Hopkinton, New York) in coarctation of aorta (CoA) patients. Background: Covered ...
The value of endothelium dependent vasodilation in diagnosing coronary artery disease and its comparison with the results of routine diagnostic tests
Objective: To determine the predictive value of flow-mediated vasodilation (FMD) compared with angina pectoris, exercise electrocardiography, and myocardial perfusion imaging (MPI). Methods: This study was carried out in ...
Mitral regurgitation after percutaneous balloon mitral valvotomy in patients with rheumatic mitral stenosis: A single-center study
Background: Percutaneous balloon mitral valvotomy (BMV) is the gold standard treatment for rheumatic mitral stenosis (MS) in that it causes significant changes in mitral valve area (MVA) and improves leaflet mobility. ...
64-Slice multidetector computed tomographic angiography and invasive coronary angiography in diagnosis of significant coronary artery stenosis
Introduction: Introduction of 64-slice multidetector computed tomography (MDCT) has resulted in a great improvement of the non-invasive coronary artery imaging. The present study aimed to evaluate the diagnostic accuracy ...
Predictive value of the fragmented QRS complex in 6-month mortality and morbidity following acute coronary syndrome
Background: Fragmented QRS encompasses different RSR' patterns showing various morphologies of the QRS complexes with or without the Q wave on a resting 12-lead electrocardiogram. It has been shown possibly to cause adverse ...
