Effect of intravenous atropine on treadmill stress test results in patients with poor exercise capacity or chronotropic incompetence
(2006)
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 ...
Coronary artery dimensions: Iranian population versus Indo-Asians and Caucasians
(2015)
Background The dimensions of the coronary arteries have been shown to vary among ethnic groups. There are no data available regarding the normal size of coronary arteries in Iranians. This study aimed to investigate normal ...
Comparison between Negative T waves characteristics in acute coronary syndrome and pulmonary embolism
(2018)
Background: Electrocardiogram (ECG) is the first available modality used in patients with chest pain and dyspnea in emergency rooms. We aimed to study differences between acute coronary syndrome (ACS) and acute pulmonary ...
Comparison between covered and bare Cheatham-platinum stents for endovascular treatment of patients with native post-ductal aortic coarctation: Immediate and intermediate-term results
(2014)
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
(2007)
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
(2014)
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. ...
Electrocardiography changes in acute aortic dissection—association with troponin leak, coronary anatomy, and prognosis
(2016)
Background Electrocardiography (ECG) offers some information that may be used to prognosticate acute type A aortic dissection (AAOD) for short- and long-term mortality. Methods We retrospectively analyzed the electrocardiograms ...
64-Slice multidetector computed tomographic angiography and invasive coronary angiography in diagnosis of significant coronary artery stenosis
(2012)
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 ...
Patient's radiation exposure in coronary angiography and angioplasty: The impact of different projections
(2014)
Introduction: We aimed to determine angiography projections with lower Dose Area Product (DAP) rate by measuring the mean DAP and fluoroscopy times in coronary angiography (CAG) and percutaneous coronary intervention (PCI) ...
Predictive value of the fragmented QRS complex in 6-month mortality and morbidity following acute coronary syndrome
(2013)
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 ...
