For such patients, blood should be drawn to check the lipids to see if the patient has elevated blood lipids. If there is elevated blood lipids, we should actively consider lipid-lowering treatment, and can take oral simvastatin and atorvastatin to actively lower blood lipids. Patients should exercise more often, mainly by walking or jogging, and use olive oil and oil blends instead of vegetable oil in cooking and stir-frying. Patients should also be careful to eat less cholesterol-rich foods, such as egg yolks and animal offal.
