WHAT CAUSES HEART ATTACKS: Heart attack is the leading cause of death in North and South America and in Europe. It is usually the result of prolonged hardening and narrowing of the arteries that direct blood into the heart. When blood vessels are healthy, oxygen-rich blood flows easily to all the muscles and organs of the body. But if they become clogged by the buildup of fatty deposits on vessel walls, blood can be cut off, killing heart muscle cells. This is called coronary heart disease, and it can lead to heart attacks or strokes.
SIGNS OF A HEART ATTACK:
- Pressure, tightness, or burning chest pain. May extend into the jaw, shoulders, back, or arms
- Nausea or vomiting
- Shortness of breath
ABOUT NANOTECHNOLOGY: Nanotechnology is science at the size of individual atoms and molecules: objects and devices measuring mere billionths of a meter, smaller than a red blood cell. At that size scale, materials have different chemical and physical properties than those of the same materials in bulk, because quantum mechanics is more important.
