Clinical Significance of ST Elevation in Lead aVR in Acute Pulmonary Embolism.
(2017)
Prognostic stratification of patients with acute pulmonary embolism (PTE) is crucial in identifying patients who would benefit from more aggressive treatment. We aimed to examine the value of ST elevation in lead aVR (STEaVR ...
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 ...
Clinical and laboratory predictors of coronary slow flow in coronary angiography.
(2017)
The coronary slow-flow phenomenon (CSFP) is a multifactorial angiographic finding with no established pathogenesis.To investigate the role of clinical profile and laboratory findings in patients with CSFP.We prospectively ...
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 ...
A pilot randomized trial of pentoxifylline for the reduction of periprocedural myocardial injury in patients undergoing elective percutaneous coronary intervention.
(2015)
Periprocedural myocardial injury (PMI) following percutaneous coronary intervention (PCI) has received great attention due to its significant association with mortality and morbidity. Accordingly, cardioprotection during ...
Association between HbA1c levels with severity of coronary artery disease and short-term outcomes of acute ST-elevation myocardial infarction in nondiabetic patients
(2015)
Background: The severity of coronary artery disease (CAD) is directly related to the quality of glucose control in diabetic patients. Additionally, mortality after an acute coronary syndrome is higher in patients with ...
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 ...
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 ...
Abnormal heart rate recovery after exercise predicts coronary artery disease severity.
(2011)
Slow heart rate recovery (HRR) after exercise is considered to represent impaired parasympathetic tone and to be a predictor of all-cause and cardiovascular mortality, but the independent value of abnormal HRR in predicting ...
