The chest tightness has been reduced. Is my symptoms caused by high blood lipids? What else should I do or what should I pay attention to? 1.Symptoms are not necessarily related to dyslipidemia, but dyslipidemia is very harmful and requires early intervention. 2.With normal liver function, it is recommended to start applying statins for lipid regulation to lower total cholesterol, LDL, triglycerides and high-sensitivity C-reactive protein, and raise HDL, so as to reduce the risk of cardiovascular disease and prevent coronary heart disease. 3.First of all, we should improve our lifestyle, such as quitting smoking If the symptoms of chest tightness and chest pain are obvious during strenuous activities or exertion and can be relieved after rest, there is a higher possibility of coronary heart disease, and treatment according to the program of coronary heart disease is needed, and coronary CTA examination is feasible if necessary to understand whether the coronary arteries are narrowed.
