Preventive measures for aortic coarctation include monitoring and controlling blood pressure, lowering blood lipids, controlling blood glucose, paying attention to warmth, quitting smoking and limiting alcohol. 1. Monitoring and controlling blood pressure: High blood pressure is an important factor that induces aortic coarctation. On the basis of aortic endothelial damage, a persistent rise in blood pressure will easily cause tearing of the arterial lining and formation of coarctation. Therefore, blood pressure should be measured regularly and timely intervention should be made when elevated blood pressure is found. 2. Reduce blood lipid: atherosclerosis can cause arterial endothelial damage and then endothelial rupture or plaque formation, and it is easy to tear the endothelium to form a sandwich when the blood pressure rises. Therefore, it is necessary to pay attention to diet, reduce sugar and fat intake, and should be treated in time when dyslipidemia is found. 3. Control blood sugar: high blood sugar will promote the development of atherosclerosis and accelerate vascular sclerosis, so diabetic patients should actively control blood sugar and regularly monitor the blood sugar level to avoid diabetic complications. 4. Pay attention to keep warm: some studies show that winter is the high incidence of aortic coarctation, which may be related to the dramatic fluctuation of blood pressure caused by cold. Therefore, you should pay attention to keep warm in winter to avoid rapid changes in blood pressure. 5. Quit smoking and limit alcohol consumption: Smoking is a clear risk factor for the development of atherosclerosis, while alcohol consumption tends to cause sharp fluctuations in blood pressure, thus both increase the risk of aortic coarctation. If there is any discomfort, we recommend that you seek medical attention.
