Coronary artery disease (CAD) is one of the most common chronic health conditions worldwide and is a leading cause of heart attacks and serious cardiovascular complications. It occurs when the coronary arteries, which supply the heart muscle with blood and oxygen, become narrowed or blocked, reducing blood flow to the heart and putting patients at risk of life-threatening conditions.

Dr. Ahmed Kamel, a specialist in cardiology and coronary artery diseases, emphasizes that early detection of coronary artery disease and adherence to appropriate treatment play a crucial role in preventing complications and improving patients’ quality of life.

What Is Coronary Artery Disease?

Coronary artery disease is a condition that develops when fatty deposits, cholesterol, and other substances accumulate on the walls of the coronary arteries, forming plaques that narrow the arteries and restrict blood flow to the heart muscle.

Dr. Ahmed Kamel explains that reduced blood flow to the heart can cause chest pain, known as angina, and may progress to a heart attack if a coronary artery becomes completely blocked.

Causes and Risk Factors for Coronary Artery Disease

Several factors increase the risk of developing coronary artery disease, including:

• High blood pressure

• High cholesterol and triglyceride levels

• Diabetes mellitus

• Smoking

• Obesity and overweight

• Physical inactivity

• Chronic stress and psychological pressure

• Family history of heart disease

• Advancing age

Dr. Ahmed Kamel emphasizes that controlling these risk factors and adopting a healthier lifestyle can significantly reduce the likelihood of developing coronary artery disease.

Symptoms of Coronary Artery Disease

Symptoms may not appear during the early stages of the disease. However, as the condition progresses, patients may experience:

• Chest pain or pressure

• Shortness of breath

• Persistent fatigue

• Pain radiating to the arm, shoulder, or jaw

• Rapid or irregular heartbeat

• Dizziness or fainting in some cases

Dr. Ahmed Kamel notes that symptoms vary from person to person and that some patients, especially those with diabetes, may not experience typical warning signs.

When Do Symptoms Become a Medical Emergency?

Immediate medical attention is required if any of the following symptoms occur:

• Severe chest pain lasting several minutes

• Significant shortness of breath

• Sudden cold sweating

• Pain spreading to the left arm or jaw

• Loss of consciousness or severe dizziness

Dr. Ahmed Kamel emphasizes that rapid medical intervention when these symptoms occur can save lives and reduce damage to the heart muscle.

ــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــــ

How Is Coronary Artery Disease Diagnosed?

Diagnosis typically involves several tests and evaluations, including:

• Reviewing medical and family history

• Physical examination

• Measuring blood pressure, cholesterol, and blood glucose levels

• Electrocardiogram (ECG)

• Exercise stress testing

• Echocardiography

• Coronary CT angiography

• Diagnostic cardiac catheterization

Dr. Ahmed Kamel explains that selecting the appropriate diagnostic tests depends on the patient’s symptoms, risk factors, and overall health condition.

Modern Treatment Options for Coronary Artery Disease

Treatment depends on the severity of the disease and the degree of arterial blockage and may include:

Medication Therapy

Medications are used to control risk factors, improve blood flow, and reduce the risk of heart attacks.

Lifestyle Modifications

• Quitting smoking

• Following a heart-healthy diet low in saturated fats and salt

• Exercising regularly

• Maintaining a healthy weight

• Controlling blood pressure and blood sugar levels

Angioplasty and Stent Placement

These procedures help open narrowed or blocked arteries and restore blood flow to the heart.

Coronary Artery Bypass Surgery

This surgery may be necessary in advanced cases or when multiple blockages are present.

Dr. Ahmed Kamel emphasizes that adherence to the prescribed treatment plan and regular follow-up visits help reduce complications and improve heart function.

Tips for Preventing Coronary Artery Disease

• Stop smoking

• Eat a balanced diet rich in fruits and vegetables

• Exercise regularly

• Maintain a healthy body weight

• Undergo regular medical check-ups

• Control blood sugar, cholesterol, and blood pressure levels

• Manage stress effectively

When Should You See a Doctor?

You should consult a doctor if you experience recurrent chest pain, shortness of breath, or unexplained fatigue, especially if you have risk factors such as diabetes, high blood pressure, or a family history of heart disease.

In conclusion, Dr. Ahmed Kamel confirms that coronary artery disease can be effectively prevented and managed through early diagnosis, adherence to treatment, and a healthy lifestyle, helping protect the heart and reduce the risk of serious complications.
