Cardiovascular disease is more common in the elderly after fracture and is an important cause of death due to deterioration of cardiovascular disease. So why is it easier to induce cardiovascular and cerebrovascular diseases after fracture? The main reasons are as follows: 1. The severe pain after fracture causes sympathetic excitation and the activity of renin-angiotensin-aldosterone system rises, leading to an increase in blood pressure and causing cerebral hemorrhage in severe cases. 2. After fracture and surgery, the body is in a highly stressful state and the concentration of catecholamines increases, which can directly damage the myocardium and increase myocardial autoregulation and ectopic pacing point activity. 3.When bedridden for a long time, the blood flow is slow and the cerebral ischemia and hypoxia are aggravated, causing the central nerve and vegetative nerve dysfunction that govern the heart, which can also lead to changes in cardiac conduction and autoregulation. In addition, due to the decline of heart function in the elderly, coupled with their own coronary heart disease, this is more likely to trigger arrhythmias, etc. To prevent and stop the occurrence and deterioration of cardiovascular disease after fracture, patients should pay attention to the following points: 1., elderly people should pay attention to the prevention and control of osteoporosis. Usually pay attention to calcium supplementation, properly enhance skeletal weight-bearing training and go outdoors to get sunlight often, which is very important to reduce the incidence of fracture. 2, to actively prevent and control hypertension, diabetes, obesity and hyperlipidemia and other common diseases. You should exercise more in moderation, eat a low-calorie, low-fat and low-salt diet, and control your weight, which can help prevent or delay the occurrence of cardiovascular diseases. In addition, once a fracture occurs in the elderly, close observation should be made to monitor changes in blood pressure and heart rhythm, and when conditions permit, early and active surgical treatment should be given to prevent the deterioration of cardiovascular and cerebrovascular disease that occurs after a fracture.
