What is ischemetic heart disease?

Answer 1

there really isn't any such thing as an ischaemic artery (it can happen, but I've never heard of it!). Rather ischemia (or ischaemia for our English and Australian friends) is a lack of sufficient oxygen delivery to a tissue. Oxygen is carried by HEMoglobin in the blood hence the iscHEMia. Ischemia is usually caused by an interruption to the blood flow to a particular area. One way to interrupt blood flow is to block an artery. (which usually deliver oxygenated blood to tissues) A blockage may be the result of a plaque (a fatty aggregation on the inside walls of an artery), or a thombus (clot), or an embolus of some sort. People often hear that they may have ischemic Heart disease. This is a condition of severely narrowed arteries (often greater than 70% of their cross sectional area may be blocked) which leads to decreased blood (and hence oxygen) supply to the muscle of the heart. This can cause Angina. If the coronary arteries completely block off, then a heart attack will ensue, where cardiac muscle dies because of lack of oxygen. Treatment ranges from medications to: lower cholesterol, decrease oxygen consumption of the heart, vasodilators to increase delivery of blood through that artery; to surgery to operate and either re-open the blocked vessel (balloon angioplasty and stenting ) or procedures to essentially replace the diseased vessels in By-pass surgery (CABG- coronary artery bypass grafting). Hopefully that helps!! Aj :)

Answer 2

The term ischemia comes from the Greek roots "isch-" and "-heme" and literally means "restriction of blood". It occurs when too little blood reaches a particular organ or tissue, which occurs when tissues are poorly perfused with blood.

Ischemia is generally considered in terms of poor perfusion and is therefore distinguished from the concept of hypoxemia, which refers to low oxygen content in the blood. The end result is generally the same, but ischemia and hypoxemia are distinct concepts.

Answer 3

Ischemic heart disease is characterized by reduced blood supply of the heart muscle due to coronary artery disease. It increases with age, smoking, high cholesterol, Diabetes and high blood pressure.

Answer 4

Ischemic stroke is the most frequent type of stroke, corresponding to about 80% of cases. This type of stroke occurs when there is an obstruction of a cerebral blood vessel by an embolus coming from the heart or by a fatty plaque. In this video, I explain the major differences between ischemic and hemorrhagic strokes (youtu.be/ajkjTpdjxV4).

Answer 5

Ischemic heart disease is basically reduced blood going to the heart. You have a blockage in the arteries which causes the blood flow to decrease with this disease.

Answer 6

The definition of an ischemic stroke is an obstruction with a blood vessel supplying blood to the brain. There are two main types of ischemic stroke embolic and thrombotic.

Answer 7

Insufficient blood reaching the tissues
