HIGH BLOOD PRESSURE AND STROKE
A stroke can occur in a person that can result in fatal conditions by affecting the brain. It occurs when the blood supply or flow to some area stops. This results in lack of oxygen and glucose to the brain cells. If not treated early, it can result in permanent brain damage.
The chances of stroke affecting a person increases by 4 to 6 times due to uncontrolled high blood pressure. The higher the blood pressure, the more the person is at risk of stroke.
High blood pressure may block the small blood vessels, or weaken the blood vessels in the brain, which can cause them to balloon up and burst. It may also harden the large arteries and cause atherosclerosis.
TYPES OF STROKE
There are 2 types of strokes:
1. Ischemic stroke: Clots form in blood vessels related to brain.
2. Hemorrhagic stroke: Any blood vessel of the brain ruptures or breaks.
SIGNS OF STROKE
Typical signs of stroke include: reduced/blurred vision, paralysis, sudden headache with nausea, brief unconsciousness, sudden confusion and numbness in face, arm or legs.
TREATMENT OF STROKE
tPA is thrombolytic agent which clears off the clots. It is given within the first 4.5 hours of the stroke symptoms. New experimental drugs are there that may stop or reverse the brain damage associated with stroke, if administered immediately.
Reducing high blood pressure and treating atherosclerosis is also vital to prevent stroke. People at risk for heart attack and stroke may be treated with aspirin or similar medications, which prevent formation of blood clots. Some people are required to have their arteries widened or plaque to be removed in order to improve blood flow.
About 80% strokes are preventable, if the risk factors are controlled before they can problems. Some risk factors, which if controlled can prevent stroke; these include:
· Atrial fibrillation (irregular heart rhythm)
· High blood pressure (greater than 140/90)
· High total cholesterol (greater than 200)
· Uncontrolled diabetes
· Excess Alcohol
· Existing carotid and/or coronary artery disease
· Being overweight/Obesity
To prevent stroke, it is very important to take adequate measures to lower cholesterol and blood pressure if they are elevated, quit smoking, control diabetes, maintain a healthy weight, and get plenty of exercise.
