How Do You Know if You Have Coronary Artery Disease

Overview

The 4 main coronary arteries are the right coronary avenue (RCA), left coronary artery (LCA), left inductive descending artery (LAD) and left circumflex artery.

What is coronary avenue disease?

Coronary artery disease is a narrowing or blockage of your coronary arteries unremarkably caused past the buildup of fatty material chosen plaque. Coronary artery disease is also called coronary center disease, ischemic heart illness and center disease.

Where are the coronary arteries? What exercise they do?

Coronary arteries are the claret vessels that supply oxygen-rich blood to your heart muscle to keep information technology pumping. The coronary arteries are directly on top of your heart muscle. You have iv chief coronary arteries:

• The right coronary artery.
• The left coronary artery.
• The left anterior descending artery.
• The left circumflex avenue.

What happens to the arteries in coronary artery disease?

Coronary artery illness is acquired past atherosclerosis. Atherosclerosis is the buildup of plaque within your arteries. Plaque consists of cholesterol, fatty substances, waste product products, calcium and the clot-making substance fibrin. As plaque continues to collect on your artery walls, your arteries narrow and stiffen. Plaque can clog or impairment your arteries, which limits or stops blood catamenia to your center musculus. If your heart does not become plenty blood, it tin can't go the oxygen and nutrients it needs to work properly. This status is called ischemia. Not getting enough claret supply to your heart musculus can lead to breast discomfort or chest pain (called angina). It likewise puts you at gamble for a middle attack.

How does plaque build-up in the arteries?

Coronary artery disease happens in everyone. The speed at which it develops differs from person to person. The procedure commonly starts when you are very immature. Before your teen years, the claret vessel walls start to evidence streaks of fatty. As plaque deposits in your avenue's inner walls, your body fights back against this ongoing process past sending white blood cells to attack the cholesterol, merely the attack causes more inflammation. This triggers yet other cells in the artery wall to course a soft cap over the plaque.

This thin cap over the plaque can suspension open (due to blood pressure or other causes). Claret jail cell fragments called platelets stick to the site of "the injury," causing a clot to form. The jell further narrows arteries. Sometimes a blood clot breaks apart on its ain. Other times the jell blocks blood menses through the artery, depriving the heart of oxygen and causing a heart attack.

The process of how plaque builds upwardly in your coronary arteries.

Who gets coronary avenue disease?

You take an increased risk of coronary artery affliction if you:

• Have a high cholesterol level (specially a high LDL "bad" cholesterol level and a low HDL "expert" cholesterol level).
• Accept high blood pressure level.
• Family history of heart illness.
• Have diabetes.
• Are a smoker.
• Are a man over 45 years of age or a mail service-menopausal woman.
• Are overweight.
• Are physically inactive.
• Are Black, Mexican American, Native American, Native Hawaiian or Asian American. The increased risks are caused by higher rates of high blood pressure, obesity and diabetes in these populations.

If y'all take these take chances factors, talk with your healthcare provider. They may want to test you lot for coronary avenue disease.

Symptoms and Causes

Location of symptoms of a center attack.

What are the symptoms of coronary artery disease?

You may not know y'all accept coronary artery disease since you lot may not accept symptoms at first. The buildup of plaque in your arteries takes years to decades. But equally your arteries narrow, you may detect mild symptoms that indicate your middle is pumping harder to deliver oxygen-rich claret to your body. The most common symptoms are chest pain or shortness of breath, especially later low-cal physical activity like walking upward stairs, but even at rest.

Sometimes y'all won't know you have coronary artery illness until you lot have a centre assault. Symptoms of a heart attack include:

• Chest discomfort (angina) described equally heaviness, tightness, force per unit area, aching, called-for, numbness, fullness, squeezing or a dull anguish. The discomfort tin can also spread to or just exist felt in your left shoulder, arms, neck, back or jaw.
• Feeling tired.
• Dizziness, lightheadedness.
• Nausea.
• Weakness.

Symptoms of a heart attack in women can be slightly different and include:

• Discomfort or hurting in the shoulders, neck, belly (belly) and/or back.
• Feeling of indigestion or heartburn.
• Unexplained anxiety.
• Cold sweat.

What should I do if I accept symptoms of coronary artery disease?

Considering the symptoms of coronary artery affliction can be symptoms of a heart assault, yous need to seek immediate assist. Call 911 if you call back yous are having symptoms of a heart attack.

If a blood jell in a coronary artery has broken loose and moved into your encephalon, it tin can crusade a stroke, although this is rare. Symptoms of a stroke include:

• Drooping on one side of your face up. Await at your smiling in a mirror or ask someone to check your grinning.
• Arm weakness or numbness.
• Difficulty speaking/slurred speech communication.

If you feel any of these symptoms, call 911. Every minute you spend without treatment increases your risk of long-term harm.

Diagnosis and Tests

How is coronary avenue illness diagnosed?

First, unless your condition is an emergency (y'all're having a heart attack or stroke), your cardiologist (heart md) will enquire yous nearly your symptoms, have your medical history, review your risk factors and perform a concrete exam.

Diagnostic tests may include:

• Electrocardiograph tests (EKG): This test records the electrical activity of the eye. Tin observe center attack, ischemia and center rhythm issues.
• Practice stress tests: This is a treadmill examination to determine how well your heart functions when it'southward working the hardest. Can detect angina and coronary blockages.
• Pharmacologic stress test: Instead of using practice to test your heart when it is working its hardest, medication is given to increase your heart rate and mimic exercise. This test can observe angina and coronary blockages.
• Coronary calcium scan: This test measures the amount of calcium in the walls of your coronary arteries, which can exist a sign of atherosclerosis.
• Echocardiogram: This test uses sound waves to see how well the structures of your heart are working and the overall function of your heart.
• Blood tests: Many blood tests are ordered for factors that bear on arteries, such as triglycerides, cholesterol, lipoprotein, C-reactive poly peptide, glucose, HbA1c (a measure of diabetic control) and other tests.
• Cardiac catheterization: This test involves inserting small tubes into the blood vessels of the middle to evaluate center function including the presence of coronary artery disease.

Other diagnostic imaging tests may include:

• Nuclear imaging: This test produces images of the heart later administering a radioactive tracer.
• Computed tomography angiogram: Uses CT and dissimilarity dye to view 3D pictures of the moving eye and detect blockages in the coronary arteries.

Management and Handling

How is coronary artery affliction treated?

Your healthcare provider volition talk to you most the best handling programme for you lot. Follow your treatment plan to reduce your take chances of problems that tin upshot from coronary artery disease, like heart attack and stroke.

Lifestyle changes

The first footstep in treating coronary avenue disease is to reduce your risk factors. This involves making changes in your lifestyle.

• Don't fume. If you smoke or utilize tobacco products, quit. Inquire your healthcare providers most ways to quit, including programs and medications.
• Manage wellness problems like high cholesterol, high claret pressure level and diabetes.
• Eat a heart-good for you diet. Talk to your healthcare provider or a registered dietitian most ways to modify your nutrition to reduce your risk of heart disease. Good dietary choices include the Mediterranean and Dash diets.
• Limit alcohol utilise. Limit daily drinks to no more one drink per day for women and ii drinks per day for men.
• Increase your activity level. Exercise helps you lose weight, improve your concrete condition and relieve stress. Most people tin reduce their risk of heart assail by doing 30 minutes of walking five times per calendar week or walking 10,000 steps per day. Talk to your healthcare provider before you commencement any exercise program.

Medications

Your healthcare provider volition recommend medications to best manage your run a risk factors for heart disease. Types of eye-related medications that may exist selected for you include:

• Medication to lower your cholesterol levels, such equally statins, bile acid sequestrants, niacin and fibrates.
• Medications to lower blood force per unit area, such as beta blockers, calcium aqueduct blockers, angiotensin-converting enzyme (ACE) inhibitors or angiotensin II receptor blockers.
• Medications to stop angina, such as nitrates/nitroglycerin or ranolazine.
• Medications to reduce the take a chance of claret clots, such as anticoagulants (including aspirin) and antiplatelets.

If yous have diabetes and coronary artery disease, you'll be prescribed medications to lower your blood carbohydrate level.

Information technology's important to take all medications every bit prescribed, including those for heart disease and all other health weather. Talk to your healthcare provider if y'all accept any questions or concerns about which medications to take or how to take them.

Procedures and surgery

Interventional procedures are nonsurgical treatments to get rid of plaque buildup in the arteries and preclude blockages. Mutual procedures are balloon angioplasty and stenting. These procedures are done with a long, sparse tube called a catheter. It is inserted into an artery in the wrist or the top of the leg through a small incision and guided to the blocked or narrowed surface area of the artery. The airship widens the diameter of the artery to restore blood menses to the middle. A stent (a small-scale metal spring-like scaffold) is left in place to keep your artery open.

Coronary artery featherbed graft (CABG) surgery involves creating a new path for blood to menstruation when there is a blockage in the coronary arteries. In most cases, the surgeon removes blood vessels from your chest, arm or leg, and creates a new pathway to deliver oxygen-rich blood to the eye.

If traditional handling options are not successful, your cardiologist may recommend other treatment options, such every bit enhanced external counterpulsation (EECP). In this procedure, inflatable cuffs (similar blood force per unit area cuffs) are used to squeeze the claret vessels in your lower body. This helps improve blood flow to the heart and helps create natural bypasses (collateral circulation) around blocked coronary arteries. Enhanced external counterpulsation is a possible handling for those with chronic stable angina who tin can't take an invasive procedure or bypass surgery and don't get relief from medication.

What are the complications of coronary artery disease?

Coronary artery illness can lead to the following other heart weather condition:

• Angina.
• Heart attack.
• Heart rhythm problems.
• Heart failure.
• Cardiogenic shock.
• Sudden cardiac arrest.

Y'all can reduce your chance of developing these heart atmospheric condition if yous follow your cardiologist's treatment plan.

Prevention

Can coronary artery disease be prevented?

You lot can certainly brand changes that will lower your run a risk of developing coronary artery disease, but this status is not 100% preventable. This is because there are two kinds of chance factors: Those that can't be inverse (nonmodifiable) and those that can be (modifiable).

Nonmodifiable risk factors include older age, male gender, a family history of heart affliction and genetic factors. Run across the question, "who gets coronary artery illness" earlier in this commodity for more information.

Still, there are many hazard factors that you can modify. These are by and large lifestyle changes like losing weight if you're overweight, stopping smoking if you smoke, keeping your blood pressure level and cholesterol level at their goal numbers and managing diabetes. Come across "lifestyle changes" under the treatment department of this article for more than examples.

Keep in mind that the more than risk factors you lot accept, the college the chance of having heart illness. Fortunately, you can cull to help yourself and reduce the take a chance of illness past taking control over your take chances factors that can exist changed.

Outlook / Prognosis

What should I look if I have coronary artery affliction? Can it be cured?

Technically coronary avenue illness tin can't be cured. If yous've been diagnosed with coronary artery affliction, follow your healthcare provider's handling program to help prevent your status from getting worse. Your treatment program may include procedures and surgery to increase the blood supply to your heart, lifestyle changes to target your take a chance factors and medications.

If your coronary artery disease has led to a center attack, your healthcare provider can recommend a cardiac rehabilitation plan to reduce your risk of futurity heart problems, regain forcefulness and improve the quality of your life.

It'southward of import to go on all follow-up appointments and have all tests ordered by your healthcare provider. These are needed to keep track of your condition, monitor how well your handling plan is working and brand adjustments if needed.

Living With

What is acute coronary syndrome?

Astute coronary syndrome is the name given to types of coronary disease that are associated with a sudden blockage in the blood supply to your eye. Some people accept symptoms earlier they have acute coronary syndrome, but y'all may non have symptoms until the condition occurs. Some people never have any symptoms. Changes caused by acute coronary syndrome can be seen on an electrocardiogram (ECG) and in blood tests. Acute coronary syndrome is defined by the location of the blockage, length of fourth dimension the artery is blocked and corporeality of damage and is defined as:

• Unstable angina: This may be a new symptom or tin happen if you have stable angina that changes to unstable angina. You may start to have angina more than often, when you are resting, or information technology may exist worse or final longer. The condition tin can lead to a heart attack. If you have unstable angina, yous will need medication, such as nitroglycerin or a procedure to correct the problem.
• Non-ST segment top myocardial infarction (NSTEMI): This is a type of heart set on (MI) that does not cause major changes on an ECG. But, a claret examination volition bear witness that there is damage to your centre muscle.
• ST segment height myocardial infarction (STEMI): This type of centre attack (MI) is acquired by a sudden blockage of the blood supply to the heart.

These are life-threatening conditions that crave emergency medical care.

How is angina different from a heart attack?

Both angina and heart attack are a consequence of coronary artery disease. The symptoms of a eye attack (myocardial infarction/MI) are similar to angina. But, angina is a warning symptom of heart illness, not a center set on.

Angina	Eye Assail
Caused by a drop in blood supply to the heart due to the gradual build-up of blockage in the arteries.	Acquired past a sudden lack of blood supply to the eye muscle. The blockage is often due to a jell in a coronary artery.
Does not crusade permanent impairment to the centre.	Tin crusade permanent impairment to the heart muscle.
Symptoms last a few minutes and usually end if you rest or take medication. You may accept chest pain or discomfort, shortness of jiff, palpitations, fast heartbeat, dizziness, nausea, extreme weakness and sweating. Symptoms are oftentimes triggered by strenuous activity, stress, eating or beingness in the common cold.	Symptoms ordinarily concluding more than than a few minutes and do not completely go away later taking nitroglycerin. Symptoms include chest hurting or discomfort; pain or discomfort in other areas of the upper body; trouble breathing or shortness of breath; sweating or "cold" sweat; feeling full, like you lot are choking or indigestion; nausea or airsickness; lightheadedness; extreme weakness; feet; fast or irregular heartbeat.
Emergency medical attention is not needed. Call your doctor if you have non had symptoms before or if your symptoms have gotten worse or happen more often.	Emergency medical attention is needed if symptoms terminal longer than 5 minutes.

A note from Cleveland Clinic

Coronary avenue disease is a narrowing or blockage of your coronary arteries ordinarily caused past the buildup of fat material called plaque. Coronary artery disease can lead to angina and heart attack. Fortunately, if you know the risk factors and symptoms for disease, you can be seen at regular intervals and your management plan can be adjusted.

There's a lot you lot can do to prevent or slow the progression of coronary artery disease. Work with your healthcare provider to brand lifestyle changes that will aid you live your life to the fullest.
