Heart Problem, Risk Factors for Stroke
In the simplest way to explain that the stroke (or stroke) is the damage caused by interruption of blood supply to the brain. Its causes are diverse, but it is important that high percentages are due to bad habits that are preventable and the problem is mainly due to:
Thrombosis. Progressive narrowing and blockage of an artery in the brain or neck, usually due to accumulation of cholesterol, fatty compound produced by the body and is responsible (among other things) to regulate the operation of certain hormones, enters the body by containing foods (red meat, eggs, seafood and most dairy products, mainly).
Embolism. Blockage of an artery in the brain or neck by a blood clot may form elsewhere in the body (usually the heart) and is transported by the bloodstream to the head.
Hemorrhage. Rupture of an artery in the brain or brain surface, which may be due to an aneurysm (thin, weak area of the artery wall) or a malformation, with which it is born, the circulatory system that supplies the brain. The bloodshed may occur inside the brain or the space between it and the outer protective membrane.

An estimated 60% of cases of stroke due to thrombosis, and 40% are divided between strokes and bleeding. However, statistics show that 50% of future cases can be avoided if you follow doctor’s orders and amending certain harmful habits in lifestyle, which directly influence the risk factors:
High cholesterol and overweight. The excess of this compound fat can be deposited in artery walls and cause the blockage of these vessels due to thrombosis, in turn excess weight strains the entire circulatory system and predisposes the person to other risk factors, as high blood pressure (hypertension). It is understood that should go to a nutritionist who prescribed the diet to improve the physical condition and thus reduce the problems mentioned here, as far as possible avoiding charlatans and opportunists who may endanger health.
Hypertension. High blood pressure damages artery walls and can increase bleeding, it favors the formation of “plugs” of blood that cause stroke; this problem may increase from 2 to 6 times the risk of stroke. To avoid major problems is essential to follow certain precautions, such as eating balanced diet, eating fruit, maintain proper weight and exercise. You should only resort to prescription drugs.
Atrial Fibrillation. Atrial fibrillation (AF) is the name given to the irregular heart rhythm that occurs in the left atrium (left upper chamber of the heart), which can get to beat up to 400 times per minute when you will usually be between 60 and 100 contractions long term, untreated AF can also weaken the heart and cause heart attack. Always consult a cardiologist for treatment, and in no way to stop.
Smoking. Compounds that are inhaled by smoking cigarette or cigar considerable damage to tissues that are on their way to the lungs, including blood vessels and arteries, causing hardening of the walls, and thereby forces the heart to work more than normal blood pressure rise. Smoking also makes blood clot more easily, increasing the risk of causing obstructions. This bad habit cans double the risk of stroke, so it is imperative to stop.
Remember also that there are other risk factors for stroke that is impossible to change, including:
* Diabetes. Circulatory problems associated with the disease may increase the risk of stroke even if tightly control blood sugar and insulin.
* Age. The risk of stroke doubles every 10 years after 35 years of age.
* Heritage. Family history of stroke indicates increased risk for the person.
* Race. Negroid descent people have twice the risk of stroke than other racial groups.
* Gender. Men have slightly higher stroke risk for women.
In addition to these risk factors, stroke also related to alcohol consumption (especially when drinking excessive quantities) and the combined use of oral contraceptives with high estrogen and snuff for women over 30 years of age.
