All of the body's tissues need oxygen to function, so ischemia can result in significant damage or even the shutdown of an organ. Among the causes of ischemia are sickle cell anemia, ventricular tachycardia, the
The inclusion of nonischemic causes of hand pain canmake the diagnosis evenmore challenging. Given the devastating consequences that may result from hand ischemia, its timely recognition and appropriate referral by practicing nephrologists is of utmost importance. There have been recent advances in the...
During ischemia, it is possible that the drop in oxygen supplied to neurons can result in a lack of ATP, which can induce a loss of the cell's ability to maintain its axonal transport system[135], and this loss of pro-survival signaling by neurotrophic factors will induce apoptosis[136, ...
Some of the causes of ischemia include: Atherosclerosis– This is one of the most common causes of ischemia and in this condition, cholesterol and other waste products from the cells accumulates on the walls of the blood vessels narrowing it and restricting the flow of blood. Blood clot– In ...
This lesson defines the concept of ischemia. Then you'll learn the major reasons for why it might occur and the signs and symptoms of various...
Chvostek's sign is de- scribed as the twitching of facial muscles in response to tapping over the area of the facial nerve (Video 1). Trousseau's sign iscarpopedal spasm that results from ischemia, such as that induced by pressure applied to the upper arm from an in- flated sphygmomanom...
How does myocardial ischemia lead to left-sided heart failure? Is hypertensive heart disease chronic? What does an enlarged left ventricle mean? What condition most commonly results in coronary artery disease? Is hypertension a kind of ischemic heart disease?
Cell death can be broadly classified into regulated cell death (RCD) and unregulated cell death a.k.a. accidental cell death (ACD). While ACD is a disordered process resulting from an unexpected attack or injury, RCD proceeds through precise signaling pathways which result in defined biochemical...
The source of exogenous mitochondria can be classified by donors and tissues. Donors can be divided into autologous and non-autologous. In order to avoid immune reaction and ensure safety, transplantation of autologously derived mitochondria is widely used to protect the heart from ischemia-reperfusion...
Explain how ischemia can cause a myocardial infarction. What are the different heart attack symptoms associated with women? Give one reason as to why the heart attack occurs to human beings. What is the most common cause of left-sided heart failure? What is meant by forward heart failure? De...
