A coronary CT calcium scan is a computed tomography (CT) scan of the heart for the assessment of severity of coronary artery disease. Specifically, it looks for calcium deposits in atherosclerotic plaques in the coronary arteries that can narrow arteries and increase the risk of heart attack. [1] These plaques are the cause of most heart ...
Gardening enthusiasts call your friends to let them know the Johnson County Master Gardeners (JCMG) will host its 15th annual Plant Sale & Flea Market on Saturday, May 11, from 9 a.m. to noon, at ...
Cardiac resynchronization therapy. Cardiac resynchronisation therapy ( CRT or CRT-P) is the insertion of electrodes in the left and right ventricles of the heart, as well as on occasion the right atrium, to treat heart failure by coordinating the function of the left and right ventricles via a pacemaker, a small device inserted into the ...
Frequency. 2% of people over 65 (developed world) [1] Aortic stenosis ( AS or AoS) is the narrowing of the exit of the left ventricle of the heart (where the aorta begins), such that problems result. [1] It may occur at the aortic valve as well as above and below this level. [1] It typically gets worse over time. [1]
Myocardial perfusion imaging. Myocardial perfusion imaging or scanning (also referred to as MPI or MPS) is a nuclear medicine procedure that illustrates the function of the heart muscle ( myocardium ). [1] It evaluates many heart conditions, such as coronary artery disease (CAD), [2] hypertrophic cardiomyopathy and heart wall motion abnormalities.
The BioButton stays on the skin with an adhesive, is waterproof, and has up to a 30-day battery life. The company says the device — which allows providers to quickly notice deteriorating health ...
Patient portals are healthcare-related online applications that allow patients to interact and communicate with their healthcare providers, such as physicians and hospitals. Typically, portal services are available on the Internet at all hours of the day and night.
Intravascular imaging. Intravascular imaging is a catheter based system that allows physicians such as interventional cardiologists to acquire images of diseased vessels from inside the artery. Intravascular imaging provides detailed and accurate measurements of vessel lumen morphology, vessel size, extension of diseased artery segments, vessel ...
Arrhythmogenic cardiomyopathy ( ACM) is an inherited heart disease. [1] ACM is caused by genetic defects of parts of the cardiac muscle known as desmosomes, areas on the surface of muscle cells which link them together. The desmosomes are composed of several proteins, and many of those proteins can have harmful mutations .
Cardiac contractility modulation is a therapy which is intended for the treatment of patients with moderate to severe heart failure ( NYHA class II–IV) with symptoms despite optimal medical therapy who can benefit from an improvement in cardiac output. The short- and long-term use of this therapy enhances the strength of ventricular ...
