Things To Know About Coronary Artery Disease

The heart usually pumps for about 3000 gallons of blood within the body each day. Like any other muscle, the heart requires a continuous supply of blood to perform its functions properly. It is the job of coronary arteries to supply blood to the heart. 

Coronary Artery Disease is also called Coronary Heart Disease and is the effect of accumulation of plaque in the arteries. It affects a large number of Americans as per the recent surveys in this regard.

What Is Coronary Artery Disease?

It refers to a condition when coronary arteries narrow down or block as a result of atherosclerosis. The plaque(cholesterol and fat repositories) in the inner walls of arteries can decrease in the flow of blood to the heart. 

This decrease in blood flow can cause chest pain, breathing problems, and several other coronary artery disease symptoms. A heart attack occurs when there is a complete blockage in the coronary artery.  

The Coronary Artery Disease develops over the years, and you can’t detect it unless there is a severe blockage in the artery or a heart attack.  

Having a healthy balanced diet can help you prevent the disease to some extent. 

What Are The Causes Of Coronary Artery Disease?

  • High cholesterol
  • High blood pressure
  • Lack of activity

What Are The Symptoms Of CAD?

  • Chest pain
  • Tightness
  • Inflammatory sensations
  • Heaviness
  • Sweating
  • Shortness of breath
  • Nausea
  • Increased heartbeat
  • Nausea
  • Palpitations
  • Indigestion
  • Muscle cramps

What Are The Risk Factors Of Coronary Artery Disease?

Age: As you age, the risks for coronary artery blockage also increases.

Sex: Coronary artery disease happens more in men as compared to women. Usually, the risk of CAD in women increases after menopause.

Unhealthy diet: Diet is one of the significant risk factors for CAD. Plan a high fiber, low saturated fat, plant-based diet, and abstain yourself from consuming unsaturated, trans fat. 

Family history: If you have someone in your family with coronary artery disease, you are at serious risk of developing the disease. The risk further increases if they have got the disease at an early age.

Smoking: Smoking increases the chances of getting coronary artery disease and can also increase your chances of death from CAD. Also, living with someone who smokes can significantly increase the risk of CAD.

Diabetes: The high blood glucose resulting from diabetes can ruin your blood vessels from within. If you have got diabetes for several years, you are on the verge of getting struck by CAD soon. Follow the preventive measures discussed later in this blog and reduce your chances of getting one. 

High blood pressure: An added exertion is put against the walls of the artery, which increases the risk of coronary diseases.

Obesity: Obesity is the primary cause of several diseases, including CAD. It can even worsen other risk factors, as well. 

Physical Inactivity: If you have a sedentary lifestyle, you are at great risk of getting the disease. Do some physical activities regularly and reduce the risk to an extent. 

Stress: Stress is also a significant risk factor that leads to coronary artery disease. To relieve stress, you can involve yourself in yoga, meditation, or other similar activities.

How Are The CADs Diagnosed?


ECG stands for electrocardiogram. It records the electrical activity of the heart and determines if it is functioning correctly. With this test, the doctor can detect the impending heart attack in advance. 

In some cases, the doctor does Holter monitor reading. Holter monitor is a small device operated with a battery. It measures and records certain heart activities like rate and rhythm. It is a portable device, and the doctor will recommend you keep wearing it wherever you go and all through your daily activities. 

Stress Tests

In stress tests, the doctor finds out how your heart performs during physical activities. He notes breathing, rhythm, and blood pressure. You can be told to ride a stationary bike or to walk on the treadmill for this test. Stress tests help determine the risk of coronary artery disease.

Laboratory Tests

Several blood tests are also done to detect the problem in the electrical activity of the heart. 

Invasive Tests

In these tests, the doctor inserts a small instrument into your blood vessels. The process is similar to that of endoscopy and is relatively pain-free.

Radiographic tests

In some instances, the doctor recommends patients to go through radiographic tests. High tech equipment like CT, MRI, and x-ray is used to diagnose the treatment for heart disease. 

How To Treat Coronary Artery Disease?

Some lifestyle changes can lower your risk of heart disease to a considerable degree. The treatment relies on several factors, including risk factors and your current health condition. 

  • Have a healthy diet
  • Avoid smoking
  • Stop alcohol consumption
  • Lose weight
  • Involve yourself in some physical activities regularly

The doctor use one of the following drugs to treat CAD:

  • Aspirin
  • Beta-blockers
  • Calcium channel blockers
  • Cholesterol-modifying medication
  • Nitroglycerine
  • Ranolazine
