More than a million Americans have a heart attack each year! Fatty matter, calcium, proteins, and inflammatory cells build up within the arteries to form plaques of different sizes. The plaque deposits are hard on the outside and soft on the inside.
When the plaque is hard, the outer shell cracks (plaque rupture), platelets (disc-shaped particles in the blood that aid clotting) come to the area, and blood clots form around the plaque. If a blood clot totally blocks the artery, the heart muscle becomes “starved” for oxygen. Within a short time, death of heart muscle cells occurs, causing permanent damage. This is a heart attack.
But, there are also numerous other factors that cause heart failure and the most often are: smoking, obesity, high cholesterol levels and unhealthy lifestyle habits. A late study has revealed that men are more vulnerable from heart attacks than women.
