Obesity is a major risk factor for coronary heart disease. Obesity is associated with high blood pressure, heart attacks, heart failure and diabetes mellitus, type 2. Your body contour or shape may also increase your risk of coronary heart disease. Research has found a higher incidence of coronary heart disease and diabetes in people who are ‘apple-shaped’ and store fat around their abdomens in contrast to those who are more ‘pear-shaped’ with fat mostly around their hips and thighs. If you are overweight or obese, losing weight may cut your risk of heart disease or heart attack considerably.
What Is a Heart Attack?
A heart attack occurs when the supply of blood and oxygen to an area of heart muscle is blocked, usually by a clot in a coronary artery. Often, this blockage leads to arrhythmias (irregular heartbeat or rhythm) that cause a severe decrease in the pumping function of the heart and may bring about sudden death. If the blockage is not treated within a few hours, the affected heart muscle will die and be replaced by scar tissue.
A heart attack is a life-threatening event. Everyone should know the warning signs of a heart attack and how to get emergency help.
The warning signs and symptoms of a
heart attack can include:
Chest discomfort. Most heart attacks involve discomfort in the center of the chest that lasts for more than a few minutes, or goes away and comes back. The discomfort can feel like uncomfortable pressure, squeezing, fullness, or pain. Heart attack pain can sometimes feel like indigestion or heartburn.
Discomfort in other areas of the upper body. Can include pain, discomfort, or numbness in one or both arms, the back, neck, jaw, or stomach.
Shortness of breath. Often comes along with chest discomfort. But it also can occur before chest discomfort.
Other symptoms. May include breaking out in a cold sweat, having nausea and vomiting, or feeling light-headed or dizzy.
Signs and symptoms vary from person to person. In fact, if you have a second heart attack, your symptoms may not be the same as for the first heart attack. Some people have no symptoms. This is called a "silent" heart attack.
The symptoms of angina can be similar to those of a heart attack. If you have angina and notice a change or a worsening of your symptoms, talk with your doctor right away. Many people suffer permanent damage to their hearts or die because they do not get help immediately.Each year, more than a million persons in the U.S. have a heart attack and about half (515,000) of them die. About one-half of those who die do so within 1 hour of the start of symptoms and before reaching the hospital.
Emergency personnel can often stop arrhythmias with emergency CPR (cardiopulmonary resuscitation), defibrillation (electrical shock), and prompt advanced cardiac life support procedures. If care is sought soon enough, blood flow in the blocked artery can be restored in time to prevent permanent damage to the heart. Yet, most people do not seek medical care for 2 hours or more after symptoms begin. Many people wait 12 hours or longer.
A heart attack is an emergency. Call 9-1-1 if you think you (or someone else) may be having a heart attack. Prompt treatment of a heart attack can help prevent or limit lasting damage to the heart and can prevent sudden death.
