Detection of Coronary Artery Disease With Micro Electro-Mechanical Sensors

Status Active, not recruiting

Clinical Trial Summary

This study aims to validate the sensor data of gyroscope and accelerometer in detection of hemodynamically significant CAD.

Clinical Trial Description

Heart diseases are the most common cause of morbidity and mortality in the western world. Coronary artery disease (CAD) alone is estimated to affect 110 million people globally and resulted in 8.9 million deaths in 2015. A hallmark phenomenon in the development of CAD is the formation of arterial stenoses eventually limiting the arterial circulation. Myocardial ischemia caused by the stenoses may present symptoms considered typical, i.e, angina pectoris chest pain, but the symptoms may vary up to an asymptomatic state. Estimating the pre-test likelihood of angiographically significant CAD (≥50% diameter stenotic CAD) is a fundamental component in the initial evaluation of symptomatic patients presenting with suspected CAD. This determination directly influences subsequent decisions for noninvasive diagnostic testing and treatment. However, studies have shown a relatively low prevalence of either ischemia or obstructive CAD on noninvasive imaging and invasive angiography (IA) in this population. Therefore, additional methods are needed to improve patient selection for such testing. Mechanocardiography (MCG) assesses the condition of the heart by measuring the mechanical activity (cardiac muscle motion) of the heart from the surface of thorax. MCG can be measured with accelerometer and gyroscope which react to recoil and vibration caused my cardiac contraction. This study aims to validate how the gyroscope and accelerometer derived parameters can identify patients with hemodynamically significant CAD in combined contrast computed tomography (CT) coronary angiography and positron emission tomography (PET) perfusion imaging in combination of high-sensitive troponin testing. The performance of different MCG algorithms will be tested offline as a head-to-head comparison with medical history, cardiovascular events, high-sensitive troponin values, coronary computed tomography angiography (CCTA) and PET scan results. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
