Little-known fat can be a heartbreaker

"If you're worried about reducing your risk of heart disease, you probably already know that you should quit smoking, eat a healthful diet, exercise regularly, keep your blood pressure in check, and make sure your cholesterol levels aren't too high. But, do you know what your lipoprotein (a) levels are? Well, if you don't have a family history of early heart disease or have unexplained heart disease yourself, you probably don't need to know how much lipoprotein (a) is lurking in your blood. But, if any males in your family had a heart attack before age 55 or any of the women had heart disease before 65, you should have your lipoprotein levels checked. Ditto if you have heart disease, and you don't have any of the usual risk factors, such as obesity and high blood pressure" - HealthDay
