1.How hypertension lead to a stroke, and cause death to a lot of people? -

quot;Hypertension or high blood pressure is a medical condition wherein the blood pressure is chronically elevated. While it is formally called arterial hypertension, the word quot;hypertensionquot; without a qualifier usually refers to arterial hypertension. Persistent hypertension is one of the risk factors for strokes, heart attacks, heart failure and arterial aneurysm, and is a leading cause of chronic renal failure.quot; - taken from stroke, also known as cerebrovascular accident (CVA), is an acute neurologic injury whereby the blood supply to a part of the brain is interrupted. Stroke can also be said to be a syndrome of sudden loss of neuronal function due to disturbance in cerebral perfusion. This disturbance in perfusion is commonly on the arterial side of the circulation, but can be on the venous side. The part of the brain with disturbed perfusion can no longer receive adequate oxygen carried by the blood; brain cells are therefore damaged or die, impairing function from that part of the brain. Stroke is a medical emergency and can cause permanent neurologic damage or even death if not promptly diagnosed and treated. It is the third leading cause of death and adult disability in the US and industrialized European nations. On average, a stroke occurs every 45 seconds and someone dies every 3 minutes. Of every 5 deaths from stroke, 2 occur in men and 3 in women. Risk factors include advanced age, hypertension (high blood pressure), diabetes mellitus, high cholesterol, and cigarette smoking. Cigarette smoking is the most important modifiable risk factor of stroke.quot; -taken from http://en.wikipedia.org/wiki/Stroke

Just like to much pressure in a garden hose it will eventually blister out and pop.

Great web page to give you all of the information the you need regarding causative factors and treatment of hypertension.

Uncontrolled hypertension may cause a blow out of an artery, but far more common is rupture of a congenital aneurym of the Circle of Willis. This can occur with normal BP.

Hypertension means high pressure in blood vessels which may cause them to rupture especially when there is aneurysm .This cause bleeding inside the skull and brain tissue ,which lead to stroke or sudden death depending on the severity of bleeding , this happens especially in arteriosclerotic people .
