Fish oil pills are proven to reduce heart attacks. Exercise is good for HDL. Eat lots of salmon (my favorite recipe: put salmon in a frying pan, pour in some orange juice-enough to almost cover the salmon, then bring to a low boil, simmer until the fish is cooked through). Replace butter with olive oil. Avoid red meat. I use free range eggs with enhanced omega-3 fatty acids. Try adding ground flaxseed to your food. My dad struggled with high cholesterol for years, suffered lots of side effects on one medication after another, then started eating flaxseed. Now he has reasonable cholesterol without taking drugs.
Consider your family history as well. Are there people with early heart attacks (before 50)? That would make it more of a worry than high cholesterol alone.
