Coronary steal is also the mechanism in most drug-based cardiac stress tests; When a patient is incapable of doing physical activity they are given a vasodilator that produces a "cardiac steal syndrome" as a diagnostic procedure. The test result is positive if the patient's symptoms reappear or if ECG alterations are seen. [citation needed]
Plaques in the walls of the coronary arteries can rupture, resulting in occlusion of the artery and deprivation of blood flow and oxygen to the heart muscle, resulting in cardiac cell death. [9] This is known as myocardial infarction. [9] A heart attack can cause arrhythmias, as well as permanent damage to the heart muscle. [25]
This blood clot may then restrict blood flow within the heart, leading to heart tissue damage, or a myocardial infarction, also known as a heart attack. [ 1 ] Coronary thrombosis is most commonly caused as a downstream effect of atherosclerosis , a buildup of cholesterol and fats in the artery walls.
This type of myoclonus often is caused by brain damage that results from a lack of oxygen and blood flow to the brain when breathing or heartbeat is temporarily stopped. Over-excitement of the sensorimotor cortex (cortical reflex myoclonus) or reticular formation (reticular reflex myoclonus) is also a cause of action myoclonus.
Coronary artery disease (CAD), also called coronary heart disease (CHD), or ischemic heart disease (IHD), [13] is a type of heart disease involving the reduction of blood flow to the cardiac muscle due to a build-up of atheromatous plaque in the arteries of the heart. [5] [6] [14] It is the most common of the cardiovascular diseases. [15]
Each year in the United States, according to the Centers for Disease Control and Prevention (CDC), about 735,000 people have a heart attack and 610,000 people die of coronary heart disease (CHD).
Cardiotoxicity is the occurrence of heart dysfunction as electric or muscle damage, resulting in heart toxicity. [1] This can cause heart failure, arrhythmia, myocarditis, and cardiomyopathy in patients. [2] Some effects are reversible, while in others, permanent damage requiring further treatment may arise. The heart becomes weaker and is not ...
A large study published in Nature Medicine reviewed the effects of GLP-1 drugs like Ozempic and Mounjaro on 175 different health outcomes. The findings show benefits for brain and heart health ...
