1.) Are there different types of heart attacks? (ehealth) Non Q-wave heart attacks and Q-wave heart attacks. Non Q-wave heart attacks occur if a coronary artery becomes partially blocked for a long period of time, causing a lack of blood flowing through it. Or if its totally blocked but blood vessels nearby are still working well, this cause the same effect. Q-wave heart attacks occur when its totally blocked and nearby blood vessels supply poor amounts of blood causing a clot that could cause a Q-wave heart attack. 2.) What is the survival rate of heart attacks? (wrongdiagnosis) 30% of heart attacks are fatal, many before they reach the hospital.

3.) What causes heart attacks? (ehealth) The term "heart attack" is often used to refer to signs and symptoms that result from the sudden blockage of blood flow to a portion of the heart. Without good blood flow, the heart does not receive enough oxygen and begins to die. People suffering a heart attack may experience symptoms such as chest pain, sweating, nausea, weakness, and shortness of breath. Each year about 1.5 million Americans have heart attacks. Heart disease remains the leading cause of death in the United States for both men and women. Heart attack is the common term for a "myocardial infarction." This refers to the permanent damage done to the heart muscle, or myocardium, when blood flow is blocked. A heart attack most commonly happens when a blood vessel that brings blood to the heart is suddenly blocked by a blood clot. 4.) What are the warning signs of heart attacks? (ehealth) but 20% of people have silent heart attacks, and they have no symptoms. 5.) How many people have heart attacks in a year? (womensheart) 1.5 million heart attacks occur in the United States each year with 500,000 deaths.

EXTRA: (ehealth)
 * The adult human heart is about the size of a clenched fist.
 * Hearts have been known to pump for 100 years without resting more that a second at a time - a feat unequaled by any man-made device.
 * The average heart beats 60 times a minute; 3,600 times an hour; 86,400 per day; 31.5 million per year, and 2.4 billion in a lifetime.
 * In an average lifetime, the heart pumps 1 million barrels of blood - enough blood to fill 3.3 supertankers - and expends more than enough energy enough to lift a battleship out of the water.
 * In the U.S., about 26.3 million men (27.6 percent) and 22.7 million women (22.1 percent) are smokers, putting them at increased risk for a heart attack.
 * About 99.5 million American adults have total blood cholesterol values of 200 mg/dL and higher (borderline high). About 39.9 million American adults have total blood cholesterol levels of 240 or above (high). An elevated blood cholesterol level is a risk factor for a heart attack.
 * As many as 50 million Americans have high blood pressure, which places them at risk for a heart attack.
 * About every 29 seconds, an American will experience a heart problem.
 * It's estimated that 7.2 million Americans age 20 and older have a history of a heart attack (4.4 million men and 2.8 million women).
 * Each year, about 1.1 million Americans are expected to have a new or recurrent coronary attack.
