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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
