Premature Coronary Artery Disease (Age <55M, <65F)

Premature coronary artery disease, or CAD, happens when your heart arteries become narrowed or blocked before age 55 in men or age 65 in women. These arteries carry oxygen-rich blood to your heart muscle. When plaque, a waxy substance made of cholesterol and other materials, builds up inside artery walls, it restricts blood flow to your heart.

This condition is different from typical heart disease because it strikes earlier in life. Many people think heart disease only affects older adults, but premature CAD shows that cardiovascular problems can begin decades earlier. Catching this condition early gives you the best chance to prevent heart attacks, chest pain, and other serious complications.

Premature CAD often runs in families and shares many risk factors with later-onset heart disease. The good news is that early detection through blood testing can identify your risk before symptoms appear. This allows you to make lifestyle changes and work with your doctor on prevention strategies that protect your heart for years to come.

• Chest pain or pressure, especially during physical activity or stress
• Shortness of breath during exercise or at rest
• Fatigue that seems out of proportion to your activity level
• Pain in your neck, jaw, shoulder, or arm
• Rapid or irregular heartbeat
• Nausea or indigestion-like discomfort
• Dizziness or lightheadedness
• Sweating without an obvious cause

Many people with premature CAD have no symptoms in the early stages. Your arteries can be significantly narrowed before you notice any problems. This is why blood testing for cardiovascular risk factors is so important, especially if you have a family history of early heart disease.

Premature CAD develops when plaque builds up in your coronary arteries earlier than expected. Family history plays a major role, especially if a parent or sibling had heart disease before age 55 for men or 65 for women. Inherited conditions like familial hypercholesterolemia, which causes very high cholesterol levels from birth, significantly raise your risk. High levels of Apolipoprotein B, or Apo B, indicate more cholesterol-carrying particles in your blood that can damage artery walls.

Lifestyle factors combine with genetics to accelerate plaque formation. Smoking damages artery linings and makes plaque buildup worse. High blood pressure forces your heart to work harder and damages artery walls over time. Diabetes and insulin resistance promote inflammation and plaque development. Being overweight, eating a diet high in saturated fats and processed foods, lack of physical activity, and chronic stress all contribute. Some people have multiple risk factors that work together to cause premature disease.

Your doctor diagnoses premature CAD through a combination of your medical history, physical exam, and testing. Blood tests are essential for identifying risk factors before symptoms appear. Apolipoprotein B, or Apo B, testing measures the number of cholesterol-carrying particles in your blood. High Apo B levels indicate increased risk for premature CAD, even when standard cholesterol tests look normal. This test is particularly valuable for young adults with family history of early heart disease.

Rite Aid offers Apo B testing as an add-on to help you understand your cardiovascular risk. This proactive approach allows you to catch problems early and work with your doctor on prevention. Additional tests may include an electrocardiogram, or EKG, which records your heart's electrical activity. Stress tests show how your heart performs during exercise. Imaging tests like coronary calcium scoring or CT angiography can visualize plaque buildup in your arteries.

• Quit smoking immediately, as it is one of the most harmful risk factors for premature CAD
• Follow a heart-healthy diet rich in vegetables, fruits, whole grains, lean proteins, and healthy fats like olive oil and fatty fish
• Exercise regularly, aiming for at least 150 minutes of moderate activity per week
• Lose weight if needed, as even modest weight loss improves heart health
• Manage stress through meditation, yoga, deep breathing, or counseling
• Take medications as prescribed, which may include statins to lower cholesterol
• Use PCSK9 inhibitors if your cholesterol remains high despite other treatments
• Take aspirin if your doctor recommends it to prevent blood clots
• Control blood pressure with medication and lifestyle changes
• Manage diabetes carefully to reduce cardiovascular risk
• Consider cardiac rehabilitation programs that provide supervised exercise and education
• Work closely with a cardiologist who specializes in preventive heart care
