What happens to the plaque when a stent is put in?

What happens to the plaque when a stent is put in?

When the tube reaches the blockage, the balloon is inflated. The balloon pushes the plaque against the wall of the artery and widens it. This helps to increase the flow of blood to the heart.

What causes plaque to break off in arteries?

Like magma underneath a volcano, rumblings in the core of a deposit, which contains dead cells, can break open the plaques. Once the plaque ruptures, a blood clot in the lumen of the artery can form.

What happens if plaque breaks loose?

A piece of plaque can break off, travel through the arteries to the brain, block blood vessels in the brain and cause a stroke or mini-stroke (TIA).

What is a risk associated with fitting a stent?

The risks associated with stenting include: an allergic reaction to medications or dyes used in the procedure. breathing problems due to anesthesia or using a stent in the bronchi. bleeding.

Which plaque is most prone to rupture?

Mechanisms of Plaque Rupture. Plaque rupture occurs where the cap is thinnest and most infiltrated by foam cells (macrophages). In eccentric plaques, the weakest spot is often the cap margin or shoulder region,86 and only extremely thin fibrous caps are at risk of rupturing.

Can a plaque rupture?

Rupture of the plaque surface, often with thrombosis superimposed, occurs frequently during the evolution of coronary atherosclerotic lesions. It is probably the most important mechanism underlying the sudden, rapid plaque progression responsible for acute coronary syndromes.

Which patient is at the highest risk of dying from a myocardial infarction?

The death rate related to acute MI is approximately three times higher in men than in women. It is more frequent in black patients compared to white patientss, an excess that disappears by age 75 years. Among the Hispanic population, coronary mortality is not as high as it is among black individuals and white persons.

How do you prevent a ruptured coronary plaque?

Aggressive cholesterol reduction and control of factors which produce endothelial injury and contribute to the development and progression of atherosclerosis such as smoking and hypertension, and prevention of intravascular thrombosis such as aspirin, may prevent plaque rupture, intravascular thrombosis and acute …

What is the mortality rate for myocardial infarctions?

Acute myocardial infarction (MI) is associated with a 30% mortality rate; about 50% of the deaths occur prior to arrival at the hospital. An additional 5-10% of survivors die within the first year after their myocardial infarction.

How long can you live with myocardial infarction?

About 68.4 per cent males and 89.8 per cent females still living have already lived 10 to 14 years or longer after their first infarction attack; 27.3 per cent males, 15 to 19 years; and 4.3 per cent, 20 years or longer; of the females, one is alive 15 years, one 23 years and one 25 years or longer.
