Atherosclerosis, Coronary Artery Disease (CAD)
Conditions
Brief summary
The MyoVista system is a novel electrocardiogram technology that provides non-invasive assessment of myocardial abnormalities by analyzing energy changes at the cellular level of the myocardium.
Detailed description
The MyoVista iECG Electrocardiograph is a diagnostic device used to process electrical signals transmitted through electrocardiograph electrodes and to detect ischemia abnormalities based on electrical waveform, patient data, demographics, algorithmic sensitivity and software based informatics. The MyoVista provides the clinician with a standard ECG conventional waveform, along with an additional report derived from the proprietary informatics exclusive to the MyoVista. The device holds a lot of promise for early intervention to properly diagnose and treat patients under risk timely and effectively. The MyoVista captures and amplifies signals from the myocardial tissue. These signals are then processed and compared to an algorithm that looks for certain changes occurring in these processed waveforms. The changes that have been identified occur much sooner than those processed by a traditional electrocardiogram (ECG). These recordings focus on early detection of myocardial abnormalities by non-linear analysis of electrical activity and physiological phenomenon. This novel assessment might be capable of detecting subclinical myocardial dysfunction in a variety of heart diseases. The study would compare MyoVista results to subclinical measures of atherosclerosis (CAC and CT angiography) in 200 subjects at risk for coronary disease. Correlations between the MyoVista reading and the presence of calcified plaque, soft plaque, CTA stenosis, will be determined. This study has the potential to confirm MyoVista as a reliable and sensitive marker of atherosclerosis. Findings may provide a strong indication for the value of a MyoVista test to confirm CAD in clinical practice, and for the clinical application of MyoVista in management of coronary disease and atherosclerosis.
Interventions
DEVICEMyoVista
The clinical set up of MyoVista™ is identical to that of a traditional 12-lead ECG but it obtains and processes signal information in a way that permits much greater resolution of the electrical activity associated with the myocardium MyoVista.
