Coronary Artery Disease: Causes, Symptoms, Treatment

Coronary artery disease (CAD) happens when plaque builds up in the coronary arteries. These are the arteries that supply oxygen-rich blood to your heart. Plaque is made up of fat, cholesterol, calcium, and other substances in the blood. Over time, plaque can harden or rupture. This causes a heart attack or angina.

What Is Coronary Artery Disease?

Coronary artery disease (CAD) is a condition in which the arteries that supply blood to the heart become hardened and narrowed. This can lead to chest pain (angina), shortness of breath, heart attacks, and other problems. CAD is the most common type of heart disease, and it is the leading cause of death in the United States.

Causes

Coronary artery disease (CAD) happens when the arteries that supply blood to the heart muscle become narrow. A buildup of plaque (a waxy substance) on the inner walls of the arteries reduces blood flow to the heart and can cause chest pain or a heart attack.

Coronary artery disease is caused by a buildup of plaque on the inner walls of the arteries. This plaque buildup narrows the arteries and reduces blood flow to the heart. This can cause chest pain or a heart attack. CAD is the most common type of heart disease in the World.

There are many different factors that can contribute to the development of coronary artery disease. Some of the more common causes include:

• Atherosclerosis: This is a condition in which the arteries become narrowed and hardened due to the buildup of plaque.
• High blood pressure: This can cause the arteries to become damaged and weaken over time.
• High cholesterol: This can also lead to the buildup of plaque in the arteries.
• Smoking: This is a major risk factor as it damages the arteries and increases the chances of developing plaque.
• Diabetes: This can cause the arteries to become stiff and narrow.

What are the main causes of coronary artery disease?

One of the main causes of coronary artery disease is the buildup of plaque in the arteries. Plaque is made up of fat, cholesterol, and other substances. Over time, plaque can harden and narrow the arteries, which can lead to a heart attack or stroke.

Symptoms

Coronary artery disease occurs when the arteries that supply blood to the heart muscle become narrowed or blocked. This can lead to chest pain (angina), shortness of breath, heart attack, and other problems.

• Burning
• Aching
• Numbness
• Fullness
• Pressure
• Heaviness
• Squeezing
• Tightness
• Discomfort

If you have CAD, you may experience one or more of the following symptoms:

• Chest pain or discomfort: This may feel like a squeezing, heaviness, or pressure in your chest. It may also feel like pain or discomfort in your shoulders, arms, neck, jaw, or back. Chest pain or discomfort is often the most common symptom of CAD.

• Shortness of breath: This can occur when the heart is not pumping enough blood to meet the body’s needs.
• Fatigue: This can occur when the heart is not pumping enough blood to meet the body’s needs.
• A heartbeat that is irregular or faster than normal: This is called arrhythmia, and it can be a sign that the heart is not getting enough oxygen.

• Heartburn or indigestion: This can occur when the stomach acid backs up into the esophagus.
• Sweating: This can occur when the body is not getting enough oxygen.

What are the risk factors for coronary artery disease?

Some of the main risk factors for developing coronary artery disease include high blood pressure, high cholesterol, diabetes, smoking, obesity, and a sedentary lifestyle.

What Puts Me at Risk?

Coronary artery disease happens when plaque builds up in your coronary arteries. Plaque is made up of fat, cholesterol, calcium, and other substances found in the blood. Over time, plaque hardens and narrows your arteries. This limits the flow of oxygen-rich blood to your heart muscle, which can eventually lead to heart failure.

The most common symptom of coronary artery disease is chest pain or discomfort, which is also called angina. Angina can feel like pressure or squeezing in your chest. It can also feel like indigestion. Not all people with coronary artery disease will have angina, but it’s a common symptom.

Coronary artery disease has many risk factors, some of which you can control and some you can’t. Controllable risk factors include:

• High blood pressure
• High cholesterol
• Smoking
• Obesity
• Physical inactivity
• Unhealthy diet

Risk factors you can’t control include:

• Age
• Gender
• Family history
• Diabetes

Diagnosis

The steps for diagnosing coronary artery disease are as follows:

• A health care provider will take a medical history and perform a physical examination.
• Blood tests may be ordered to look for factors that can lead to coronary artery diseases, such as high cholesterol or diabetes.

• An electrocardiogram (EKG) may be done to check for changes in the heart’s electrical activity that can be seen with coronary artery disease.

• A stress test may be done to see how well the heart handles physical activity and stress. This test may be done using exercise on a treadmill or by injecting a medicine that makes the heart work harder while it is being monitored.

• Cardiac catheterization (angiography) is sometimes done to look at the coronary arteries directly. A thin, flexible tube (catheter) is inserted into an artery in the leg and passed up to the heart. Dye is then injected into the coronary arteries through the catheter so that they can be seen on an x-ray.

• Computed tomography (CT) or magnetic resonance imaging (MRI) may be done to create detailed pictures of the coronary arteries.

• If coronary artery disease is found, further tests may be done to see if the heart is damaged and to find out how severe the disease is.

How is coronary artery disease diagnosed?

There are a few ways that coronary artery disease can be diagnosed. One way is through a coronary angiogram, which is an x-ray of the arteries. Another way is through a stress test, which measures how well the heart is functioning during physical activity.

Treatment

There are a number of treatments available for coronary artery disease, depending on the severity of the condition.

Lifestyle changes: There are many different lifestyle changes that can be helpful in treating coronary artery disease. Some lifestyle changes that may be helpful include eating a healthy diet, exercising regularly, quitting smoking, and managing stress. Making these lifestyle changes can help to improve your overall health and reduce your risk of developing coronary artery disease or experiencing a heart attack or stroke.

Manage your stress level: There are a few things you can do to manage stress levels while receiving coronary artery disease treatment. First, make sure to communicate any concerns or questions you have with your care team. Secondly, take some time for yourself each day to relax and tour (!?) from the juggling of treatment and life responsibilities. Lastly, do not hesitate to ask for support from family and friends when needed. All of these measures can help decrease stress and improve your overall treatment experience.

Healthy Eat: The best way to treat coronary artery disease is through healthy eating habits. This means eating plenty of fruits and vegetables, lean proteins, and whole grains. Additionally, it is important to avoid processed foods, sugary drinks, and excessive amounts of saturated and unhealthy fats. By following a healthy diet, you can significantly improve your overall cardiovascular health and reduce your risk of experiencing a heart attack or other serious cardiovascular event.

Alcohol Limit: If you have coronary artery disease, alcohol may pose a serious threat to your heart health. While moderate alcohol consumption is generally considered safe, large amounts of alcohol can lead to potentially life-threatening cardiac problems. Therefore, it is important to speak with your doctor about how much alcohol is safe for you to consume.

Avoid cigarette smoke: Smoking is a major risk factor for coronary artery disease, so it’s important to avoid cigarette smoke if you have this condition. There are many ways to do this, including quitting smoking, avoiding secondhand smoke, and using medications or other treatments to help you quit.

Focus on healthy weight: It is important to focus on maintaining a healthy weight if you are treating coronary artery disease. This is because being overweight or obese can contribute to the development of the disease. Losing weight can help to reduce the risk of developing coronary artery disease.

Prevention: In treating coronary artery disease, prevention is key. Taking steps to prevent the disease from progressing is essential to keeping your heart healthy. Some preventive measures you can take include quitting smoking, eating a healthy diet, and exercising regularly.

Coronary artery bypass: Coronary artery bypass grafting (CABG) is a type of surgery that is used to treat coronary heart disease. The surgery involves taking a healthy blood vessel from another part of the body and using it to bypass the blocked or narrowed coronary artery. This surgery can improve blood flow to the heart and relieve symptoms such as chest pain.

Angioplasty: Coronary angioplasty is a procedure to widen narrow or blocked coronary (heart) arteries. A balloon-tipped catheter is inserted into the narrowed section of the coronary artery. The balloon is then inflated. This widens the artery and improves blood flow to the heart muscle.

Medications: There are many medications that can help treat coronary artery disease. Some of these medications can help to prevent the disease from getting worse, while others can help to improve the symptoms. Some of the most common medications used to treat this condition include aspirin, beta-blockers, and statins.

Exercise: Regular exercise is one of the best things you can do for your heart health. That’s because it lowers your risk of heart disease and improves your heart’s function. If you have coronary artery disease, exercise can also help improve your symptoms.
