Like "Hi Lady Trolley, It looks like you have extensive family history of heart disease. I suggest you have regular heart checkups with your doctor and periodic blood workups to keep a close eye on cholesterol levels even if you’re ok now. Also, make sure you keep your blood pressure in check. If any of those parameters are out of control then make sure you take the medications your doctor prescribes to rectify any of those conditions if any. Also, ask your doctor about starting an Aspirin regimen to keep your blood thin to help avoid any heart attacks. You are to be commended on making favorable lifestyle choices because to you it’s a must and not an option. Keep your weight under control and stay physically fit by getting involved in aerobic activity such as cycling indoors and outdoors, using elliptical machines at the gym, brisk walking and swimming. Make sure you get clearance from your doctor on what you can and can’t do before embarking on such activity. Also, make sure you make favorable food choices by raising your fiber intake, cutting back on animal fat such as bacon, butter, whole milk products and fatty cuts of meat. Increase your intake of fruit, vegetables and good sources of fat such as nuts, avocados, canola and olive oil. Reduce sugar from beverages and other sources because sugar transfers to fat in your body and make sure you reduce portion sizes. One last thing never smoke and try to avoid second hand smoke. If you follow these general recommendations and stay healthy throughout life then you can reduce your chances of having heart problems even if you have a strong genetic tendency. I hope this was helpful. "
