Understanding coronary artery disease: Causes and symptoms

Coronary artery disease (CAD) is a term that often comes up in discussions about heart health, but what does it really mean?

In simple terms, CAD is a condition where the major blood vessels that supply your heart with blood, oxygen, and nutrients (coronary arteries) become damaged or diseased.

This usually happens due to the buildup of plaque, a combination of fat, cholesterol, and other substances. This guide aims to unpack the causes, symptoms, and treatments of CAD in an easy-to-understand manner, making sense of the science behind it.

The journey of CAD begins with the buildup of plaque in the coronary arteries, a process known as atherosclerosis. This buildup can start early in life and progress over the years, narrowing the arteries and making it harder for blood to flow through.

When the blood flow to your heart is reduced or blocked, it can lead to serious health problems, including heart attacks.

Several factors can increase your risk of developing CAD. These include smoking, high blood pressure, high cholesterol, diabetes, being overweight, leading a sedentary lifestyle, and having a family history of heart disease.

Each of these factors can contribute to the damage of your coronary arteries, accelerating the buildup of plaque.

The symptoms of CAD might not be obvious at first and can vary widely from person to person. Some people might not experience symptoms at all until they have a heart attack.

However, the most common symptom is angina, which is chest pain or discomfort that occurs when your heart muscle doesn’t get enough blood.

Angina can feel like pressure or a squeezing sensation in your chest, and it might also be felt in the shoulders, arms, neck, jaw, or back. Other symptoms can include shortness of breath, fatigue, and palpitations.

When it comes to diagnosing CAD, doctors have several tools at their disposal. These can include physical exams, blood tests, electrocardiograms (EKGs), echocardiograms, stress tests, and coronary angiograms.

These tests help doctors understand how well your coronary arteries are functioning and whether there’s any significant blockage.

Treatment for CAD has come a long way, and there are now many options available depending on the severity of the condition. Lifestyle changes are the first line of defense.

This can include eating a heart-healthy diet, exercising regularly, quitting smoking, and managing stress. Medications may also be prescribed to help manage symptoms and control risk factors like high blood pressure, high cholesterol, and diabetes.

In more severe cases, procedures like angioplasty and stent placement or coronary artery bypass surgery may be necessary.

Angioplasty involves using a tiny balloon to widen the blocked artery, often followed by placing a stent to keep the artery open.

Coronary artery bypass surgery involves taking a blood vessel from another part of your body and using it to reroute blood around the blocked artery.

Prevention is also a key part of managing CAD. This includes regular check-ups with your doctor, monitoring your heart health, and making lifestyle changes that reduce your risk factors.

By understanding CAD and taking steps to manage your risk, you can protect your heart and lead a healthier life.

In summary, coronary artery disease is a common yet serious condition that affects the blood vessels of the heart. It’s caused by a buildup of plaque, leading to narrowed arteries and reduced blood flow to the heart.

While it can have serious consequences, understanding the causes, recognizing the symptoms, and following through with effective treatment and lifestyle changes can greatly improve outcomes for those affected.
