May 5, 2021 · Myocardial ischemia, also called cardiac ischemia, reduces the heart muscle's ability to pump blood. A sudden, severe blockage of one of the heart's artery can lead to a heart attack. Myocardial ischemia might also cause serious abnormal heart rhythms. Treatment for myocardial ischemia involves improving blood flow to the heart muscle.
Jun 6, 2014 · Mechanisms of Plaque Rupture, Erosion, and Thrombosis. Atherosclerosis alone may obstruct coronary blood flow and cause stable angina pectoris, but this is rarely fatal in the absence of scarring of the myocardium, which can elicit an arrhythmia presenting as sudden cardiac death.

Oct 1, 2024 · It happens when the brain's blood vessels become narrowed or blocked. This causes reduced blood flow, known as ischemia. Blocked or narrowed blood vessels can be caused by fatty deposits that build up in blood vessels. Or they can be caused by blood clots or other debris that travel through the bloodstream, most often from the heart.
Atherosclerosis is a specific type of arteriosclerosis. Atherosclerosis is the buildup of fats, cholesterol and other substances in and on the artery walls. This buildup is called plaque. The plaque can cause arteries to narrow, blocking blood flow. The plaque also can burst, leading to a blood clot. Although atherosclerosis is often considered ...
Clots form in the brain and interrupt blood flow, clogging arteries and causing blood vessels to break, leading to bleeding. Rupture of the arteries leading to the brain during stroke results in the sudden death of brain cells owing to a lack of oxygen. Stroke can also lead to depression and dementia.
Sep 29, 2018 · Cerebrovascular accident (CVA) is the medical term for a stroke. A stroke is when blood flow to a part of your brain is stopped either by a blockage or the rupture of a blood vessel.

Feb 27, 2023 · A ruptured blood vessel: This is most commonly associated with an aneurysm, which is an outpouching of a blood vessel. A brain aneurysm that is fragile or becoming larger is most likely to rupture, especially if blood pressure is elevated. A leaking blood vessel: A cerebral aneurysm can slowly leak instead of rupturing. An arteriovenous ...
