A heart attack occurs when the usual blood supply to a specific part of the heart muscle itself (the myocardium) is harshly abridged or even stopped utterly. The medical term called a heart attack is the myocardial infarction. If one or more of coronary arteries that supply blood to the muscle of heart is blocked then it causes the diminution or stoppage of blood supply.
This might be happened due to the accumulation of plaque (clotting of fatty substances) and this condition is also known as atherosclerosis. The plaque may ultimately tear, rupture or burst creating a condition where the artery is blocked by a blood clot formation. This condition may lead a person to a severe heart attack.
A statistical structure
A heart attack is sometime called as a coronary occlusion or coronary thrombosis. It is a calculated medical fact that the heart disease is one of the most dangerous health hazards that is mostly faced by the people of 50 years and older in USA. Up to 1 in 3 American female may die of heart disease, and two times as many women die from cardiovascular diseases than males.
Key points of coronary heart attack
Laboratory investigations, number of surveys and clinical studies represent that certain personal characteristics and standard of living can lead to augmented dangers of a heart attack by coronary heart disease. These dangerous facts are called the “risk factors”. The well known risk factors are high blood cholesterol, high blood pressure, diabetes mellitus and smoking. Some other risk factors that may cause the increasing of the risk of getting a heart attack are sedentary life-style, an obesity, certain drugs and aggressive response to stress.
Reducing the risk factors
In the last two decades, thousands of Americans have became concerned about these risk factors and have tried to diminish them by conducting medical awareness and by shifting their lifestyles. Many adults have tried to stop smoking. The medicinal control of the high blood pressure has significantly developed. The usual cholesterol level of the people has decreased significantly over the last two decades, perhaps due to changes in their dietary habits and improved physical exercise. This effort to adapt the risk factors almost undoubtedly has kept contribution in the declining the death rate from coronary heart disease in the USA as well as the entire world.
Consciousness and seriousness is needed
On the whole, coronary related problems have reduced about almost 25 percent during the last decade. Some of this reduction is certainly due to the better medical treatment of heart attack patients, but it is true that a great percentage is associated with the modification of the risk factors. The total inhabitants have become more conscious of the significance of heart disease and coronary heart problems. Most of the key risk factors are silent. They must be sought dynamically, and the responsibility for their exposure deceits with each of us as the individuals to a great extent. Regular check-ups are predominantly required if there is a family heredity of high blood pressure, diabetes, high cholesterol levels or heart disease.
