A heart attack occurs because there is a blockage in the arteries that nourish the heart with oxygen-rich blood. It is a life-threatening emergency where every second counts. Heart attacks are the major leading cause of death in Canada. Over one third of population die from heart attacks. Most Canadians have overcome this disease and the numbers of death have been reduced. Our scientists have concentrated on this disease and they have published a lot of information regarding to this disease. That has helped a lot of Canadians especially immigrants. .
This essay will be focused on the causes of heart disease, how to prevent it, symptoms of this disease, and effects it has on our society. Very specifically giving tables, graphs, surveys from Canadians, and other biological information will describe each one of these subjects. The goal of this project is to provide a Canadian overview of disease's current and past activities.
In all forms of heart disease the blood supply to the muscle is inadequate. The blood supply is limited because arteries conducting blood to the heart become narrowed due to number of blood vessel diseases. When there are vessel diseases, the fat deposits in inner wall lining of an artery. The fat particularly consists of cholesterol and other materials in the blood such as compounds that facilitate clotting. As the fat builds up, the artery narrows, restricting blood passage. Heart attacks occur due to many other causes such as nutrition, smoking, excessive alcohol use, mental stress, high blood pressure, diabetes, inactive leisure time, and multiple risk factors.
Firstly, high cholesterol diet produces fatty streaks, which raises the blood lipid levels to a high fat. The blood carries oxygen to the heart, and if enough blood and oxygen cannot reach the heart, it may suffer chest pain. If the blood supply to a portion of the heart is completely cut off by a blockage, the result is a heart attack.
