As we mentioned in Part I, except cancer and heart disease, stroke is the third leading cause of death. Recent estimates of stroke events in the United States place the number between 700,000 to 750,000 per year, about one quarter of all stroke victims die as a direct result of a stroke or complications. Stroke is caused by uncontrolled diet that is high in saturated and trans fats, as a result of bad cholesterol building up in blood vessels that block the circulation of blood in the body including the brain. If oxygen is not delivered to brain cells, some cells die and can not play, then May you have a stroke. Other strokes happen when blood vessels in the brain ruptures causing the cells in the brain that is deprived of oxygen. In this article we will discuss ischemic stroke in great detail than 80% of all strokes are ischemic.
Stroke occurs when there is a problem with the amount of blood in ischemic stroke that is too little blood to the brain. They occur when the brain arteries are narrowed or blocked, causing difficult to decreased blood flow (ischemia). This deprives your brain cells with oxygen and nutrients, and cells may begin to die within a few ischemic strokes are:
1. Thrombotic stroke:
These moves are also sometimes referred to as large artery strokes. The process leading to thrombotic stroke is complex and occurs over time. Thrombotic stroke can be caused by arterial walls slowly thickening and hardening of the arteries as a result of being injured. Such injuries signals the immune system to release white blood cells at the site causing stroke. Thrombotic stroke occurs when the inner walls of arteries were injured in result of less nitrogen oxide is produced, causing hardening of the arteries. If a blood clot then blocks the already narrowed artery and stops the oxygen part of the brain, we have a thrombotic stroke.
2. Embolic stroke
Embolic stroke occurs when a blood clot or other particle forms in a blood vessel away from your brain. This is usually caused by a dislodged blood clot that has traveled through the blood vessels until it becomes wedged in the arteries. It is also caused by irregular beating in the two upper heart chambers. This abnormal heart rhythms can lead to poor blood flow and blood clots.
