Heart attacks are the leading cause of death in the United States, surpassing the number of cancer deaths.  In 2008 alone, heart disease caused up to 25 percent of deaths, which is almost 1 in every 4. Coronary heart disease is the most common type of heart disease, affecting more men than women. Annually, 785,000 Americans have coronary attack for the first time and 470,000 who already had one or more have another attack.

As reported by the Center for Disease Control and Prevention, high blood pressure, smoking, and high cholesterol are the three major causes of heart attack and conditions like being overweight, poor diet, physical inactivity, excessive alcohol intake, and diabetes also add to the risk of heart attack.

Early detection is the critical point when it comes to the likelihood of survival, as nearly half of the heart attacks occur outside the hospital.  A study done by the Center for Disease Control and Prevention has shown that 92 percent of the sufferers experienced chest discomfort as an early symptom of a heart attack. Only 27 percent of them knew that this symptom indicated a heart attack and knew that it was the time to call 9-1-1.

Symptoms Of A Heart Attack

The 6 symptoms below are the major early signs of heart attack. They could let you know that you are at risk of having a heart attack up to a month before it strikes.

1. Chest Discomfort

Chest discomfort comes in many different forms, such as burning sensation, pinching, or feeling pressure in the chest.  These unpleasant symptoms may occur during physical activity or while you are at rest.  In case you experience any unusual sensation in the chest, consult a doctor as soon as possible.

Note:  One can be having a heart attack without feeling discomfort in the chest, as it typically occurs in women.

2. Fatigue

Unexplained fatigue may also indicate that a heart attack is on its way.  As arteries begin to close up, the heart starts working much harder, and this in turn makes the performance of simple tasks much more exhausting.  Consequently, this may lead to sleeping much longer or feeling the urge to take a few naps during the day.

3. Persistent Cough

Persistent cough which doesn’t seem to subside after an extended period of time can be a sign of heart failure. This happens as result of the blood accumulated in the lungs, which is caused by the struggle of the heart to supply the body with sufficient amount of blood.  White or pink mucus could be a product of blood leakage, so pay attention to this sign!

4. Dizziness

In case of compromised heart function the blood circulation is restricted, causing lack of oxygen in the blood. This causes symptoms like dizziness and lightheadedness, which seek immediate medical attention.

5. Shortness of Breath

Shortness of breath is yet another common sign of an impending heart attack. The lungs and the heart wok in synergy, so as heart`s function deteriorates, the lungs fail to get sufficient amount of oxygen they need to function optimally. Hence, this leads to shortness of breath and difficulty breathing.

6. Swelling

Last but not least, heart`s struggle to pump blood may cause the blood to swell, resulting in a bloating-like effect.  The legs, feet, and ankles are the major points of swelling as they are at the greatest distance from the heart.  Peripheral cyanosis, a blue tinge in the extremities or on the lips, is also possible.
