Why Healthy People Over 60 Have SUDDEN Heart Attacks And How To Prevent It.

Could a dangerous blockage be growing inside your heart while you feel completely healthy? In this educational presentation, Dr. Leonid Kim explains how coronary artery disease can remain silent for years—even in active adults whose cholesterol results and routine checkups appear normal. You will learn how the coronary arteries supply oxygen to the heart, why the left anterior descending artery is often called the “widowmaker,” and how plaque can grow inside the artery wall without immediately restricting blood flow. Dr. Kim also explains positive arterial remodeling, the difference between stable and unstable plaque, and how a relatively small plaque can suddenly rupture and trigger a blood clot that completely blocks an artery within minutes. The video also explores how intense physical activity can create a supply-and-demand imbalance in someone with a partial blockage, why some heart attacks occur without a completely blocked artery, and how atrial fibrillation may increase strain on the heart. You will discover warning symptoms that older adults should never ignore, including unusual exhaustion, shortness of breath, chest pressure, cold sweating, nausea, jaw or arm discomfort and a sudden feeling that something is seriously wrong. Finally, Dr. Leonid Kim discusses two tests used to evaluate coronary artery disease: the coronary artery calcium scan, also known as a CAC score, and CT coronary angiography, which can provide a more detailed view of coronary plaque. Screening tests are not appropriate for every person. Their potential benefits, limitations, radiation exposure, contrast risks and costs should always be discussed with a qualified healthcare professional. Watch until the end to learn the practical steps that may help protect your heart, including controlling blood pressure, managing blood sugar, staying physically active and discussing your individual cardiovascular risk with your doctor.
