Coronary artery disease - symptoms and causes (2023)

General description

Coronary arterial disease is a common heart condition.The main blood vessels that provide the heart (coronary arteries) struggle to send blood, oxygen and sufficient nutrients to the heart muscle.Cholesterol deposits (plaques) in heart arteries and inflammation are usually the cause of coronary artery disease.

Signs and symptoms of coronary artery disease occur when the heart does not obtain sufficient oxygen blood.If you have coronary arterial disease, reduced blood flow to the heart can cause chest pain (angina) and shortness of breath.A complete blockade of blood flow can cause a heart attack.

Coronary arterial disease usually develops for decades.Symptoms may go unnoticed until a significant block causes problems or heart attacks.

Coronary arterial disease can also be called coronary heart disease.

Coronary artery disease, also called CAD, is a condition that affects your heart.It is the most common heart disease in the United States..This happens when coronary arteries struggle to provide sufficient blood, oxygen and nutrients in the heart.Cholesterol deposits or signs are almost always culprits.These accumulations reduce their arteries, reducing blood flow to your heart.This can cause pain in pain in pain in pain pain in pain in pain in pain pain in pain in pain in pain in pain in pain.The chest, shortness of breath or even a heart attack..Usually it has been developing for a long time.Much, patients do not know that they have it until there is a problem.But there are ways to prevent coronary artery disease and the ways of knowing if it is at risk and ways to treat it.

Who understands this?

Anyone can develop..Sher when fats, cholesterols, and other substances meet along the walls of their arteries.This process is called atherosclerosis.Obstructing the blood flow.There are a number of risk factors, ordinary red flags that can contribute to this and finally lead to leading to leading to coronary arterial disease.First, aging can mean more damaged and narrow arteries second, men usually have a higher risk.But the risk of women increases after menopause.Existing health conditions are also important.High blood pressure can thicken its arteries, reducing its blood flow.High cholesterol levels can increase the plate accumulation rate.Diabetes is also associated with greater risk, as is overweight.Your lifestyle also plays an implanting.Physical inactivity, long periods of stress not relieved in your life, a harmful diet and smoke can increase your risk.And finally, family history.If a relative close to an early age with heart disease with heart disease has been diagnosed, was diagnosed, diagnosed, was diagnosed, was diagnosed, was diagnosed, if a relative close to heart disease with heart disease, was diagnosed, diagnosed,It was diagnosed, was diagnosed, was diagnosed, if a relative near a heart disease with heart disease with heart disease, has a higher risk.All these factors together can paint an image of their risk of developing..

What are the symptoms?

When the coronary arteries narrow, the heart does not get enough blood in oxygen.Observe these signs and symptoms of pressure or oppression in the chest.This pain is called angina.It may seem that someone is standing on your chest.When their hearts cannot pump enough blood to meet your body's needs, you can develop difficulty breathing or extreme fatigue during activities.And if an artery is fully blocked, it will lead to a heart attack.Sweat, however, many heart attacks have minimal or null symptoms and are later found during routine tests.

How is diagnosed?

Diagnosis.Start talking to your doctor.They will analyze their medical history, will do a physical examination and order routine blood analysis.Depending on this, you may suggest one or more of the following tests: an electrocardiogram or ECG, an echocardiogram or heart wavet tests, stress testing, cardiac catheterization and angiogram, or a cardiacConnecticutScan.

How is it treated?

Treating coronary arterial disease usually means making changes in your lifestyle.This can be healthy foods, exercise regularly, lose overweight, reduce stress or quit smoking.Good news is that these changes can do a lot to improve your perspective.Life translates into healthier arteries.When necessary, treatment may involve drugs such as aspirin, cholesterol, beta -blockers or certain medical procedures such as angioplasty or perfortunate surgery of the coronary artery.

Now that?

Find out that it has a coronary artery disease can be overwhelming.But be encouraged.Your stress can make a big difference.Better heart health begins by educating.So he is not afraid to seek information and ask doctors about coronary arterial disease.If you want to learn even more about this condition, watch our other related videos or visit wish you the best.


Symptoms may not be recognized at first, or can only occur when the heart hits hard as during exercise.As coronary arteries continue to be limited, less and less blood reaches the heart and symptoms can become more serious or frequent.

Signs and symptoms of coronary artery disease may include:

  • Chest pain (angina).You may feel pressure or oppression in the chest.Some people say someone is standing in the chest.Chest pain usually occurs on the medium or left side of the chest.Strong activity or emotions can trigger angina.The pain usually disappears a few minutes later the activation event ends.Some people, especially women, pain may be brief or clear and the direction in the neck, arm or back.
  • Difficulty breathing.You may feel that you cannot recover your breath.
  • Fatigue.If the heart cannot pump enough blood to meet the needs of your body, you can feel extraordinarily tired.
  • Myocardial infarction.A completely blocked coronary artery will cause a heart attack.Classic signs and symptoms of a heart attack include pain or overwhelming chest, shoulder or arm, shortness of breath and sweating.Women may have less typical symptoms, such as pain in pain in neck pain or jaw, nausea and fatigue.Some heart attacks do not cause remarkable signs or symptoms.

When to see a doctor

If you think you are having a heart attack, call 911 immediately or the local emergency number.If you do not have access to emergency medical services, get someone to the nearest hospital.Stop just like a last option.

Smoking or having high blood pressure, high cholesterol, diabetes, obesity or a strong family history of heart disease increases the likelihood of obtaining a sickness of the coronary artery.If you have a high risk of coronary artery disease, talk to your medical care supplier.It is possible to need evidence to verify the narrow arteries and coronary artery disease.

Atherosclerosis development

Coronary artery disease - symptoms and causes (1)

Atherosclerosis development

If there is much blood cholesterol, cholesterol and other substances can form deposits (plates) that accumulate on the artery walls.A blood clot.Blood plates and clots can reduce blood flow through an artery.

Coronary arterial disease begins when fats, cholesterols and other substances accumulate on the inner walls of the arteries of the heart.This condition is called atherosclerosis.The accumulation is called plate.The plate can make the arteries restrict, blocking the blood flow.The plate can also explode, which leads to a blood clot.

In addition to high cholesterol, damage to coronary arteries can be caused by:

  • Resistance to diabetes or insulin
  • Hypertension
  • Do not exercise enough (sedentary lifestyle)
  • Use of smoking tobacco

Risk factors

Coronary arterial disease is common.Age, genetics, other health conditions and lifestyle options can affect the health of heart arteries.

The risk factors of coronary artery disease include:

  • Age.Aging increases the risk of damaged and narrow arteries.
  • Sex.Men usually have a higher risk of coronary artery disease.However, the risk of women increases after menopause.
  • Family history.A family history of heart disease makes you more likely that a coronary artery disease.This is especially true if a close relative (father, brother) has developed a heart disease at an early age.Heart disease before 55 or if your mother or sister developed it before age 65.
  • Smoking.If he smokes, he renounces.Slipping is bad for heart health.People who smoke have a significantly higher risk of heart disease.Second -hand smoke breathing also increases the risk.
  • Hypertension.Unmistved high blood pressure can make the arteries harsh and rigid (arterial stiffness).Coronary arteries can become narrow, reducing blood flow.
  • High cholesterol.Very bad blood cholesterol can increase the risk of atherosclerosis.Bad cholesterol is called low density lipoprotein cholesterol (LDL).It is not enough cholesterol, called High Density Lipoprotein (HDL), also leads to atherosclerosis.
  • Diabetes.Diabetes increases the risk of coronary heart disease.Type 2 diabetes and coronary artery disease share some risk factors such as obesity and high blood pressure.
  • Overweight or obesity.Excessive body weight is bad for overall health.Obesity can lead to type 2 diabetes and high blood pressure.Press your medical care provider that healthy weight is for you.
  • Chronic kidney disease.Having a long -term kidney disease increases the risk of coronary artery disease.
  • Do not exercise enough.Physical activity is important for good health.Lack of exercise (sedentary lifestyle) is related to coronary artery disease and some of its risk factors.
  • Very stress.Emotional stress can damage arteries and worsen other risk factors for coronary artery disease.
  • Non -healthy diet.Eating foods with a large number of saturated fats, trans fats, salt and sugar can increase the risk of coronary artery disease.
  • Alcohol consumption.Heavy alcohol consumption can cause heart damage to the heart.Other risk factors for coronary artery disease may also get worse.
  • Amount of sleep.Very little and too much sleep has been related to a higher risk of heart disease.

Risk factors usually occur together.A risk factor can trigger another.

When they are grouped, certain risk factors further increase the likelihood of developing a coronary artery disease.For example, metabolic syndrome, a group of conditions that includes high blood pressure, high blood sugar, excess body fat at the waist and high levels of triglycerides, the risk of coronary artery disease increases.

Sometimes coronary artery disease develops without any classic risk factor.Other risk factors for coronary artery disease may include:

  • Breathing breaks during sleep (obstructive sleep apnea).This condition causes breathing to stop and start during sleep.It can cause sudden drops in blood oxygen levels.The heart must work harder.Blood pressure increases.
  • High sensitivity C-reactive protein (HS-CRP).This protein appears in higher quantities than usual when there is inflammation somewhere in the body.HS-CRPLevels can be a risk factor for heart disease.It is believed that, as the coronary arteries narrow, the level ofHS-CRPIn the blood rises.
  • High triglycerides.This is a type of fat (lipid) in the blood.High levels may increase the risk of coronary artery disease, especially for women.
  • Homocysteine.Homocysteine is an amino acid that the body uses to make protein and build and maintain the fabric.But high levels of homocysteine may increase the risk of coronary artery disease.
  • Pre eclampsia.This complication of pregnancy causes high blood pressure and an increase in protein in the urine.It can lead to a higher risk of heart disease later in life.
  • Other complications of pregnancy.Diabetes or high blood pressure during pregnancy are also known risk factors for coronary artery disease.
  • Certain autoimmune diseases.People who have conditions such as rheumatoid arthritis and lupus (and other inflammatory conditions) have a higher risk of atherosclerosis.


Coronary arterial disease can lead to:

  • Chest pain (angina).When the coronary arteries narrow, the heart may not have enough blood when they need it, how to exercise.This can cause chest pain (angina) or shortness of breath.
  • Myocardial infarction.A heart attack can occur if a cholesterol plate opens and making a blood clot.A blood flower flower flower.Lack of blood can damage the heart muscle.The amount of damage depends in part of the speed.
  • Cardiac insufficiency.High heart or high blood pressure can make the heart weak or rigid, so it is more difficult to pump blood.Heart failure is when the heart does not pump blood as it should.
  • Irregular heart rhythms (arrhythmias).There is not enough blood in the heart can alter normalization of the normal heart, causing irregular heartbeat.


The same lifestyle habits used to help treat coronary artery disease can also help prevent it.A healthy lifestyle can help keep arteries strong and away from the plate.To improve heart health, follow these tips:

  • Stop smoking.
  • Control high blood pressure, high cholesterol and diabetes.
  • Exercises frequently.
  • Keep a healthy weight.
  • Eat a diet with low fat and low salt content, rich in fruits, vegetables and whole grains.
  • Reduce and manage stress.
