Heart attack is the number one killer disease in North America.
Heart disease is the number one killer of American women, and nearly half of all heart attack deaths each year happen to women. Furthermore, women are less likely to survive a heart attack than are men.
The medical term for heart attack -- myocardial infarction -- means "death of heart muscle.“
Heart attacks are not sudden most victims are warned well in advance by episodes of chest pain, shortness of breath, or fatigue.But the heart attack itself may seem sudden.
A stroke occurs when a blood vessel that carries oxygen and nutrients to the brain is either blocked by a clot or bursts. When that happens, part of the brain cannot get the blood (and oxygen) it needs, so it starts to die.Clots that block an artery cause ischemic (is-KEM-ik) strokes. This is the most common type of stroke, acounting for approximately 88 percent of all strokes.
Ruptured blood vessels cause hemorrhagic (hem-o-RAJ-ik) or bleeding strokes.
