Hypertension cardiovascular examination mainly have electrocardiogram, heart ultrasound, chest X-ray, because hypertension long-term control is not good, will lead to hypertensive heart disease, in the electrocardiogram will reflect the left ventricular high voltage, myocardial ischemia and so on changes; X-ray on the chest film will reflect the boot-shaped heart; cardiac ultrasound will appear in the performance of the left ventricular hypertrophy, the cardiac cavity enlarged. In addition to cardiovascular examination, blood can also be drawn for 4 items of coagulation, blood lipids, liver and kidney function, blood glucose, and 4 items of hypertension, because these tests can be abnormal, for example, hypertension should be looked at 4 items of hypertension and adrenal CT, to rule out the possibility of secondary hypertension. People with poor kidney function may cause high blood pressure, as well as lipids, blood sugar and other risk factors need to be detected, in addition to checking the carotid ultrasound to see if there is any plaque, stenosis in the carotid region, and if there are any risk factors for coronary heart disease caused by high blood pressure. Hypertension can also lead to retinopathy, so the examination of the fundus is necessary.
