background: more diagnostic techniques require a better understanding of the forces and stresses developed in the wall of the left ventricle. the aim of this study was to differentiate significant coronary artery disease (cad) patients using a non-invasive quantification of myocardial wall stress in the diastole phase. methods: sixty male subjects with sinus rhythm (30 patients with significant...

Background: Evidence suggests hypovitaminosis D is associated with increased risk of coronary artery disease (CAD) and its extent and related risk factors. However, some investigations have produced contrary results. Therefore, we aimed to evaluate the association between serum vitamin D levels and the severity of premature coronary artery involvement. Methods: This randomized prospective, cas...

background one of the most important causes of mortality in developed and developing countries is coronary artery disease. coronary artery disease (cad) may develop by deposition of lipid, fibrous or calcified debris on the surface of the coronary artery lumen. fibrous plaque and calcified plaque may cause substantial stenosis of coronary arteries leading to ischemia of heart muscle while lipid...

conclusions cgm is a non-invasive technique recently developed for quantitative three-dimensional vectorial analysis of myocardial activity and detection of ischemia and infarction. this technique is clearly more sensitive and more specific than a standard resting 12-lead ecg. results the coronary angiography showed a normal coronary artery in 263 patients (67.4%). a median of cgm score was 1 (...

Coronary Artery Disease (CAD) is a leading cause of life-threatening ventricular arrhythmias (LTVAs). This study aimed to identify distinct clusters CAD individuals based on QRS morphology using 3-nearest neighbors clustering algorithm. Cluster 1, characterized by the lowest amplitudes and widest complexes, was strongly associated with LTVA risk.

BACKGROUND AND AIMS The association between gallstone disease and coronary artery atherosclerotic disease (CAD) remains unclear. To clarify their relationship, patients with CAD newly diagnosed by coronary angiography were investigated in this cross-sectional study. METHODS The study cohort consisted of 1,270 patients undergoing coronary angiography for the first time between January 2007 and...

Coronary artery disease (CAD) is a chronic progressive with social significance, result of obstructive or non- atherosclerotic plaque accumulation in the epicardial arteries. CAD one leading causes for deterioration quality life and cardiovascular mortality. has dynamic character its major clinical presentations are: acute coronary syndromes / STEMI, NSTEMI, UA/ syndromes. In this case report w...

objectives to evaluate predictive value of vessel specific coronary artery calcium (cac) score in predicting obstructive coronary artery disease. patients and methods in this diagnostic test study we evaluated patients with coronary computed tomography angiography (ccta) and cac score which had been referred to two referral radiology center in tehran, iran and finally we selected 2525 patients ...

cardiovascular disease (cad) screening in asymptomatic patients with diabetes mellitus is controversial. an exercise stress test is a safe and effective initial testing for ischemic heart disease (ihd) screening. treadmill stress test is not the best screening method for a particular patient who is not able to exercise, abnormal electrocardiogram (ecg) or positive exercise treadmill test (ett) ...
