What is cerebral ischemia?
Focal cerebral ischemia (FCI) is often results from a blood clot in the brain. The blood flow in the affected area is reduced. The reduction could be severe or mild but usually FCI causes irreversible injury to sensitive neurons.
Patient experiences severe ischemia what can happen to heart?
Ischemia is a medical term meaning insufficient oxygen ... usually caused by insufficient blood flow. If the ischemia is occurring in the heart it will probably cause some type of cardiac problem: anything from mild cardiac failure (not pumping all the blood that the body demands) to pain (angina) to death of some or all of the cardiac muscle (a heart attack).
What is the scientific name for a heart attack?
Myocardial infarction (often abbreviated MI) is the medical terminology for heart attack. An MI occurs when a blood clot reaches cardiac tissue resulting in death of the affected area. Normally tests for such a condition would include blood tests (e.g. troponin T) and ECG. Occaisionally an echocardiogram might be ordered to establish an ejection fraction.Myocardial infarction (MI) or acute myocardial infarction (AMI), is commonly known as a heart attack.Cardiac ArrestYou can call it a 'myocardial infarction' if you want. I'd stick with 'heart attack' because people don't say "huh?".It can also be known as either of the following: Acute myocardial infarction (AMI for short) Or Myocardial infarction (or MI for short).
Is a myocardial infarction a stroke?
A myocardial infarction is a heart attack. It is caused when the cells of the muscle of the heart do not get enough oxygen and glucose, resulting in anaerobic metabolism and buildup of products of that metabolism, resulting in cellular acidosis, shutdown of cellular metabolism, and finally cell death and necrosis. In the overwhelming number of casea, this process results from the blockage of a coronary artery by a thrombus formed when a cholesterol plaque ruptures, causing a clot to form. It can be caused by several other things, however. Severe dehydration, severe hypotension, partial blockage of an artery by a large plaque that has not ruptured and other low flow states can result in not enough oxygen and glucose getting to the cells. Also, anything that increases the metabolic demands on the heart muscle can cause similar effects - sepsis with shock, toxins, drugs, and poisonings.
Can heat cause a high heart rate?
Heat related to the human body causes vein and artery dilation (expansion) and decreases pressure or blood flow (blood pressure). If a person has plaque severe enough that the body requires a certain pressure to push blood through it and you take that pressure away, the artery can spasm and close or be deprived of needed blood flow causing ischemia (lack of oxygen) or infarct (myocardial infarct or heart attack).
Which of the following is a life threatening condition associated with severe colonic dilatation?
C.difficile infecton
What is a life threatening condition associated with severe colonic dilatation?
i really dont know
Differentiate myocardial ischemia from myocardial infarction?
Ischaemia is the lack of blood supply to a tissue which start anaerobic respiratory mechanisms. Infarction is cell death through apoptosis resulting from prolonged or severe ischaemia. Clinicaly myocardial infarction will be more painful and is unrelieved by rest. On ECG infarction will reult in ST segment elevation where ischaemia will result in ST segment depresion (unless it is a posterior MI!). In MI there will also be raised biochemical markers hours later such as creatine kinase and troponin.
What causes global ceregral ischemia?
Global cerebral ischemia can be caused by a variety of factors, including cardiac arrest, severe hypotension, blood loss, or as a complication of aortic dissection. This condition leads to a widespread lack of blood flow to the brain, resulting in brain cell damage and potentially leading to serious neurological deficits or even death.
How does cerebral palsy affects the mind?
Generally no but in some severe cases mental retardation is associated with the condition.
Is a condition associated with severe emotional and physical problems that are closely linked to the menstrual cycle?
premenstrual dysphoric disorder
What are two common symptoms associated with acute myocardial infarction?
severe crushing chest pain that may radiate down the arm and into the jaw sweating shortness of breath nausea lack of consciosness
What is the medical term meaning insufficient blood supply to head?
The medical term for insufficient blood supply to the head is cerebral ischemia. This condition can lead to a lack of oxygen and nutrients reaching the brain, causing symptoms such as dizziness, confusion, and in severe cases, stroke. Treatment typically involves restoring blood flow to the affected area to prevent further damage.
What happens when coronary circulation is prevented in humans?
Preventing coronary circulation in humans can lead to a heart attack or myocardial ischemia, which occurs when the heart muscle is deprived of oxygen and nutrients. This can result in chest pain, shortness of breath, and damage to the heart muscle. In severe cases, it can lead to heart failure or even death.
What is cerebral ischemia?
Focal cerebral ischemia (FCI) is often results from a blood clot in the brain. The blood flow in the affected area is reduced. The reduction could be severe or mild but usually FCI causes irreversible injury to sensitive neurons.
What are the symptoms of intestinal ischemia?
Symptoms of intestinal ischemia include sudden abdominal pain. The pain can range from mild to severe. A sudden needs to use the bathroom, frequent and forceful stools, tenderness in the abdomen, bloody stools, vomiting and fever.
Why does laxative drugs given to patients after myocardial infarction?
severe straining can do much damage to a person with a MI and avoid constipation
