What Happens If 3 Arteries Are Blocked – Blocked arteries are a condition in which a waxy substance called plaque builds up inside the coronary arteries.
. Over time, the plaque hardens and narrows the arteries. This restricts the flow of oxygen-rich blood to organs and other parts of the body.

What Happens If 3 Arteries Are Blocked
When plaque builds up in the walls, including the inside of the arteries, the condition is called atherosclerosis. Atherosclerosis is a disease in which plaque builds up inside the arteries. As arterial plaque accumulates over many years, the artery wall thickens. This narrows the opening, reducing blood flow and oxygen to the cells. While arterial plaque builds up, you may not notice the problem until a significant blockage occurs. The buildup of plaque increases the likelihood of blood clots forming in the arteries.
The Warning Signs Of Clogged Arteries
Eventually, a section of plaque may rupture (split) inside the artery. When this happens, pieces of blood cells called platelets stick to the site of injury. They can join together and form blood clots. If the clot becomes large enough, it can partially or completely block the flow of oxygen-rich blood to the body.
If the blockage increases to the point of completely blocking the artery and is not treated quickly, part of the heart, brain, muscles and vital organs that the artery supports begin to die, which can lead to serious problems including stroke, blindness, gangrene, organ failure or even death.
. Plaque may partially or completely block blood flow through large or medium-sized arteries in the heart, brain, pelvis, legs, arms, or kidneys. In this case, various diseases may occur. These include:
If any of these happen, the artery may be blocked and blood flow interrupted. If an artery supplying the heart or brain is blocked, a heart attack or stroke may occur. If the artery that supplies oxygen to the extremities (often the legs) is blocked, gangrene can occur. Gangrene is the death of tissue.

Atherosclerosis is a slowly progressive disease that can begin in childhood. For some people, it progresses rapidly after age 30. For others, it does not become dangerous until they are in their 50s or 60s. As we age, arteries tend to harden.
. Researchers continue to search for the causes of atherosclerosis, or clogged arteries. They hope to find answers to questions such as
Certain characteristics, conditions, or habits may increase your risk of disease. These conditions are called risk factors. The more risk factors you have, the more likely you are to develop atherosclerosis.
You can control most risk factors and help prevent or slow the development of atherosclerosis. Other risk factors cannot be controlled.
Blockage & Human Age Correlation
Although age and a family history of early heart disease are risk factors, having one or both factors does not mean you will develop atherosclerosis. Genetic influence and prevention of atherosclerosis are often reduced even in adults when other risk factors are controlled.
Research shows that an increasing number of children and young people are at risk of developing atherosclerosis. This is due to a number of reasons, including the rise in childhood obesity.
Smoking plays an important role in the development of atherosclerosis of the coronary arteries, aorta and leg arteries. Because of this, fat deposits are more likely to form and grow larger and faster.
Inflammation is the body’s response to injury or infection. Damage to the inner walls of arteries appears to stimulate inflammation and promote plaque growth.

People with low levels of CRP may develop atherosclerosis more slowly than people with high levels of CRP. Research is currently being conducted to see if reducing inflammation and lowering CRP levels can reduce the risk of atherosclerosis.
The lining of the artery, called the endothelium, can be damaged by high levels of cholesterol and triglycerides, toxic substances in cigarette smoke, high blood sugar and other factors in the blood. High blood pressure can also damage the lining of the artery. When a blood vessel is damaged, atherosclerosis begins and plaques form.
Due to the damage, fat, cholesterol, platelets, cellular waste and calcium begin to deposit in the walls of the arteries. These substances can stimulate cells in the artery wall to produce other substances. As a result, more cells accumulate in the inner layer of the arterial wall, where atherosclerotic lesions form. These cells accumulate and many divide. At the same time, fat accumulates in and around these cells. They also form connective tissue. This cluster is called a plaque. Large and medium-sized arteries are usually affected. These cells and surrounding material greatly enlarge the endothelium. The diameter of the artery decreases and blood flow decreases, which reduces the supply of oxygen.
Most damage occurs when plaques become brittle and rupture. Rupture plaques lead to the formation of blood clots, which can block blood flow or break off and travel to another part of the body. In one such situation, if a blood clot blocks a blood vessel supplying the heart, it causes a heart attack. If it blocks a blood vessel supplying blood to the brain, it causes a stroke. If the blood supply to the arms or legs is reduced or blocked, it can lead to difficulty walking and eventually gangrene.
Small Vessel Disease
Taking steps to control risk factors can help prevent or slow clogged arteries, atherosclerosis, and related diseases. The risk of developing atherosclerosis increases with the number of risk factors you have.
Other steps that can prevent or slow clogged arteries or atherosclerosis include knowing your family history of atherosclerosis. If you or someone in your family has a disease associated with atherosclerosis, be sure to tell your doctor.
If lifestyle changes are not enough, your doctor may prescribe medications to control risk factors for atherosclerosis. Take all medications as directed by your doctor.
. Many people don’t know they have this disease until they have a medical emergency, such as a heart attack or stroke.
What Are Clogged Arteries Causes & Symptoms?
Some people may have signs and symptoms of the disease. Signs and symptoms will depend on the arteries affected.
The coronary arteries supply the heart with oxygen-rich blood. If plaque narrows or blocks these arteries (a condition called coronary artery disease), angina is a common symptom. Angina is chest pain or discomfort that occurs when the heart muscle does not receive enough oxygen-rich blood.
. You may feel it in your shoulders, arms, neck, jaw or back. The pain of angina may even look like an upset stomach. The pain usually worsens with physical activity and goes away with rest. Emotional stress can also trigger pain.
. Symptoms of microvascular coronary artery disease include angina, shortness of breath, trouble sleeping, fatigue (tiredness), and lack of energy.
Cerebral Bypass Surgery
. If plaque narrows or blocks these arteries (a condition called carotid artery disease), you may experience stroke symptoms. These symptoms may include:
Plaques can also build up in the large arteries that supply oxygen-rich blood to the legs, arms, and pelvis (a condition called peripheral artery disease).
The renal arteries deliver oxygen-rich blood to the kidneys. If plaque builds up in these arteries, you may develop chronic kidney disease. Over time, chronic kidney disease causes a slow loss of kidney function.
Early kidney disease often has no signs or symptoms. As the disease worsens, this can lead to fatigue, changes in the way you urinate (more or less frequently), loss of appetite, nausea (nausea), swelling of the hands or feet, itching or numbness, and difficulty concentrating.
Heart Block: Types, Causes, Symptoms, And Risk Factors
Your doctor diagnoses clogged arteries or atherosclerosis based on your medical and family history, physical examination, and test results.
If you have atherosclerosis, you may be treated by a primary care physician, such as an internist or family doctor. Your doctor may recommend other health care professionals if you need specialized treatment, such as:
During a physical examination, your doctor may listen to your arteries for an abnormal whistling sound called a murmur. Your doctor may hear a murmur when he places the stethoscope on the affected artery. An abscess may indicate poor blood flow due to plaque buildup.
Your doctor may also check to see if any part of your pulse is weak or absent (for example, in your leg or foot). A weak or absent pulse may be a sign of a blocked artery.
What Is Peripheral (leg) Artery Disease?
Your doctor may recommend one or more tests to diagnose atherosclerosis. These tests can also help your doctor know the extent of your disease and plan the best treatment.
Blood tests check the levels of certain fats, cholesterol, sugar and proteins in the blood. Abnormal levels may be a sign that you are at risk for atherosclerosis.
An ECG is a simple and painless test that records the electrical activity of the heart. The test shows how fast the heart is beating and whether its rhythm is fast or irregular. An ECG also records the strength and timing of electrical signals passing through the heart.
An ECG can reveal signs of heart damage caused by coronary artery disease. The test can also look for signs of a previous or current heart attack.
