What is a primary cause of coronary heart disease?

Hypertension, or persistently high blood pressure, puts extra strain on artery walls and contributes to damage and narrowing of the coronary arteries. This makes it a primary risk factor for coronary heart disease. Eating fruit and exercising vigorously are generally beneficial for heart health, while deep vein thrombosis is a clot in a vein and is not a primary cause of coronary heart disease.
