Causes Of Heart Disease

The initial hour of a heart attack is known as the "golden hour." If we can get help during that first hour, the chances of recovery are more likely. But still many people vacillate to get help when they first experience symptoms. It is always best to get help at the earliest. Often they are afraid of the embarrassment of going to the emergency room and finding that nothing is wrong. So, it is important that we know the symptoms that may indicate that a heart attack is in progress. Prevention is always better than cure and the earlier the better.

Many of the symptoms of heart attack can be brought on by digestive disturbances or other less serious conditions. Many people suffering from gastric problems feel a burning sensation in their chest. But only urbane medical tests can determine for sure if we are having a heart attack. Heart attacks may vary from person to person, and from heart attack to heart attack. Women, for instance, may experience "atypical' symptoms such as pain between the shoulder blades rather than a severe chest pain. This may result in them delaying looking for treatment. That is a great mistake. Never should we ignore we the slightest of pain or discomfort caused in and around the chest area.

With time, cholesterol buildup can occur in these blood vessels in the form of plaque. This narrows the artery and can restrict the amount of blood that can flow through it. If the artery becomes too narrow, it cannot supply enough blood to the heart muscle when it becomes stressed. Just like arm muscles that begin to hurt if you lift too much, or legs that ache when you run too fast; the heart muscle will ache if it doesn't get adequate blood supply. This ache is called angina. This is when the heart attack may occur. The heart does not receive enough blood thus blocking the way and causing a blockage.

If the plaque ruptures, a small blood clot can form within the blood vessel and intensely block the blood flow. When that part of the heart loses its blood supply completely, the muscle dies. This is called a heart attack, or an MI - a myocardial infarction. Depending on the blockage it could be a minor attack or a severe one. But even a minor can lead to a major attack.

The heart is a muscle like any other in the body. It needs constant blood flow to supply oxygen to allow it to work. When there isn't enough oxygen, the muscle starts to suffer, and when there is no oxygen, the muscle starts to die.

Heart muscle gets its blood supply from arteries that start in the aorta and run on the surface of the heart, known as the coronary arteries. The right coronary artery supplies the right ventricle of the heart and the inferior (lower) portion of the left ventricle. The left anterior descending coronary artery supplies the majority of the left ventricle, while the circumflex artery supplies the back of the left ventricle. Regular exercise, fat free food including fresh foods and vegetables and a stress free lifestyle can lead to a happy heart.
