Patients with high diastolic blood pressure are in a relatively serious condition. Patients with high diastolic blood pressure are commonly seen in middle-aged and young adults, but rarely in the elderly. These patients have some primary causes of hypertension, such as renal artery stenosis or adrenal pheochromocytoma, which can cause high blood pressure, so for these patients it is a serious condition, and surgery is recommended for complete treatment. In addition, patients with high blood pressure may also have cardiovascular and cerebrovascular complications, such as myocardial infarction, insufficient blood supply to the cerebral arteries, and cardiovascular and cerebrovascular atherosclerosis, so high blood pressure is a more serious condition and should be promptly intervened and treated.
