Breaking Myths About Coronary Artery Disease: What Science Says

Coronary artery disease (CAD) is one of the leading causes of heart-related deaths worldwide. Unfortunately, misinformation about CAD often leads to unnecessary fear, poor management, and missed opportunities for prevention. In this blog, we will break down common myths about CAD and uncover the scientific truth behind them.

Myth #1: Only Older Adults Get Coronary Artery Disease

Fact: While the risk of CAD increases with age, younger individuals can also develop the condition. Factors such as genetics, poor lifestyle choices, obesity, and diabetes can contribute to early onset CAD, even in people in their 30s or 40s.

Myth #2: Chest Pain Is the Only Symptom of CAD

Fact: Although chest pain (angina) is a common symptom, CAD can manifest in various ways, including shortness of breath, fatigue, nausea, dizziness, and even silent heart attacks with no obvious symptoms. Women, in particular, may experience atypical symptoms such as jaw pain or indigestion.

Myth #3: If You Have CAD, You Should Avoid Exercise

Fact: Regular physical activity is one of the best ways to manage CAD. While intense workouts should be approached with caution, moderate activities such as walking, cycling, and swimming help improve heart health by strengthening the cardiovascular system and improving circulation.

Myth #4: CAD Is Only a Problem for People Who Are Overweight

Fact: While obesity is a risk factor, even individuals with a normal body weight can develop CAD. Factors such as high cholesterol, smoking, high blood pressure, and stress contribute to plaque buildup in the arteries regardless of body weight.

Myth #5: If You Have No Symptoms, You Don’t Have CAD

Fact: Many people with CAD experience no symptoms until a major cardiac event occurs, such as a heart attack. Regular check-ups, cholesterol tests, and blood pressure monitoring are essential to detect CAD early and take preventive measures.

Myth #6: Heart Disease Runs in Families, So There’s Nothing You Can Do

Fact: While genetics play a role in CAD risk, lifestyle choices significantly influence disease progression. A healthy diet, regular exercise, and quitting smoking can greatly reduce the risk, even for those with a family history of heart disease.

Myth #7: Medications Alone Can Cure CAD

Fact: Medications help manage CAD by lowering cholesterol, controlling blood pressure, and preventing clot formation. However, they work best when combined with lifestyle changes such as a heart-healthy diet, stress management, and regular exercise.

Myth #8: Low-Fat Diets Are the Best Way to Prevent CAD

Fact: Not all fats are bad. Healthy fats, such as those found in nuts, avocados, and fish, support heart health. A well-balanced diet that includes whole grains, lean proteins, and fiber-rich foods is more effective in preventing CAD than simply cutting fat intake.

Conclusion

Misinformation about coronary artery disease can lead to poor health choices and increased risk. Understanding the science behind CAD allows individuals to take proactive steps in preventing and managing the disease. Regular check-ups, a balanced lifestyle, and proper medical guidance remain the best defense against CAD.
