General features
Each year over one million Americans from attack of heart disease. Although heart disease remains the leading cause of death in the United States have made great strides have been made over the past decade in the treatment of heart attacks and help people who have both suffered life is a permanent full , active.
The most common type of heart attack caused by coronary thrombosis, when a blood clot (thrombus) blocks ormost of the blood vessels that feed the heart muscle. As a result of shortage of blood, part of the muscle can be damaged and lost the capacity to contract can be. This is known as a myocardial infarction. If the stroke is small, electrical impulses, control of the heart s (beats) are not disturbed contractions, the chances of recovery are excellent.
Coronary heart disease
coronary thrombosis is a manifestation of coronary artery disease.As we age, our blood vessels tend to their elasticity, a process known as atherosclerosis lose. The arteries can also be reduced or blocked by deposits of fatty material called atheroma, a condition called atherosclerosis. Atherosclerosis is a progressive and usually produce no symptoms until there is a significant block blood flow. Sometimes, in fact, the first symptom of this disease is the heart of a heart attack.
Although the exact cause ofAtherosclerosis is not known, it was shown that some risk factors to identify population groups that help develop more. Three major risk factors include high cholesterol and other blood fats, high blood pressure (hypertension) and cigarette smoking. Others include diabetes, obesity, sedentary lifestyle, aging, being male, and inheritance.
Atherosclerosis begins as fatty streaks formed on the inner wall of an artery, usually their point of branching outand disrupts the smooth flow of blood. As an accumulation of adipose tissue patch, the inner wall is narrower, blood flow inhibits significantly. Artery continues as the construction progresses tissue thin, and with time, the fat deposit a hard mass of adipose tissue with a hard outer shell of cells a commemorative plaque. As plaque grows and thicken, they undermine the artery wall that blood flow is blocked and there is always turbulent. This turbulence mayTrigger of blood for a blood clot (thrombus) in a partial or total closure of the artery. Furthermore, a fragment of the clot (embolism) are carried through the bloodstream and block an artery at some distance, the tight spot.
Heart attacks sometimes occur in people with little or no coronary disease. Some experts believe that a sudden contraction or spasm of the coronary arteries can cause attacks of these hearts. It seems that coronary spasm may occurThis is completely free of atherosclerosis (as in a shot that has this condition), and this would explain why many people suffer from angina and other heart problems without proof that blocks arteries.
