@heartdocjeng: You've probably heard someone say "Heart attacks aren't caused by plaque—they're caused by blood clots." Technically, a blood clot is often what suddenly blocks the artery. But that's only the final step. Most heart attacks begin years earlier as cholesterol plaque builds up inside the artery. When that plaque ruptures, your body forms a blood clot over the injury—and that's what can completely block blood flow to the heart. Understanding the difference matters because preventing plaque formation is one of the most effective ways to reduce your risk of heart attack. #MedicalMyths #DoctorDebunks #HealthFacts #HeartAttack #HeartHealth #Cardiology #PreventiveCardiology
