These unchangeable factors are independent and as we observed they are related to different conditions. These factors may be explained too. For example, the first mentioned factor, age, differs from women to men. This risk factor may occur in men over the age of 45 and in women after the age of 55.

A family history of early heart disease is also divided for men and women. An early heart disease is considered for men younger than 55 and for women younger than 65.

A personal history of CAD means an angina, a previous heart attack or a surgical procedure to increase the blood flow to the heart.

These were the unchangeable risk factors. Among the other type of risk factors, that a patient can change, we have to remember smoking, high blood pressure, high blood cholesterol, obesity, physical inactivity or diabetes.

Along with the risk factors we also have to mention the warning signs and symptoms of a heart attack.

Chest discomfort is one of the most common warning signs. In most of the cases discomfort occurs for a few minutes but keeps on coming back. Patients feel an uncomfortable pressure, squeezing, fullness or pain. In some cases the heart attack pain may feel like indigestion or heartburn.

Discomfort may occur in other areas of the body, not only in the chest. The pain may occur in the arms, the back, neck, jaw or stomach.

Shortness of breath is also a common warning sign. It may occur with the chest discomfort but sometimes can even occur before it.

Along with these common symptoms, a patient may develop symptoms that include breaking out in a cold sweat, nausea or dizziness too.

The sings and the symptoms are different from one person to another. It was noticed that for a second heart attack the symptoms are different from the first one. There are cases when people do not experience symptoms. Their problem is called silent heart attack.

A very important advice is to go to a hospital when you experience these symptoms.

The ways of diagnosing heart attack are the electrocardiogram (ECG or EKG), blood tests, nuclear heart scan, cardiac catheterization and coronary angiography.
