Surprising health news today, as we learn that former President George W. Bush underwent a procedure to have a stent placed in his heart. A Bush spokesperson says he had the surgery a day after a blockage was found in an artery. So how can an artery blockage eventually cause a heart attack?
We all know plaque is bad, blocks your blood vessels. Plaque is formed by LDL cholesterol in the blood, the bad cholesterol, think of it as L for lousy.
Building up on the wall of your arteries, forming plaque. Plaque can accumulate slowly, over time, narrowing the blood vessels, like something building up inside a pipe.
This narrowing, in the blood vessels leading to your hear, can cause chest pain, called angina. It can also cause a heart attack.
Did you ever wonder how seemingly healthy people can have a heart attack? This may surprise you, most heart attacks happen in people with no symptoms.
In people whose arteries are less than 50% blocked, here's how: cholesterol can cause unstable bubbles or blisters of plaque to form in your arteries.
These can be incredibly dangerous, most are covered by a cap, but inflammation and stress can cause the cap to thin and rupture, resulting in a clot that blocks the flow of blood to the heart.
Robbed of oxygen, the heart muscle can't function properly, heart attack.
ROBBED OF OXYGEN, THE HEART MUSCLE CAN'T FUNCTION PROPERLY. HEART ATTACK.
