The current prevalence of hypertension in China is around 30%, which means that 30 out of 100 people can be definitively diagnosed with hypertension. The age of onset of hypertension is getting earlier and earlier, and now people in their 30s can be clearly diagnosed with hypertension. In the guidelines, senior age and super senior age are clearly defined, and those who are older than 70 years old are considered senior patients, and those who are older than 80 years old are super senior patients, so senior hypertension generally refers to hypertensive patients who are 75 years old or older. For elderly hypertension requirements is not required to reduce the systolic blood pressure to below 140mmHg, but below 150mmHg is acceptable, because the elderly exist cerebrovascular blood supply, must maintain a certain degree of high blood pressure to ensure adequate blood perfusion, so for the elderly patients over 75 years of age hypertension lowering target can be appropriately relaxed to 150mmHg.
