Blood pressure 170/105 combined with other target organ damage is more dangerous; if only simple hypertension, timely control can improve the quality of life. Blood pressure of 170/105mmHg is the second level of hypertension, at this time, if the blood pressure control is not stable, it is easy to cause damage to the heart, kidneys, brain and blood vessels and other target organs, thus inducing myocardial infarction, heart failure, cerebral hemorrhage and other cardio-cerebral vascular events, which is a greater threat to the life and health. However, if there are no obvious clinical symptoms, and the examination shows good cardiac and renal function, no history of coronary heart disease, cerebral infarction, diabetes mellitus, etc., then follow the doctor’s instructions to take antihypertensive drugs, such as hydrochlorothiazide, nifedipine, etc., which can effectively control the blood pressure, prevent the damage to the target organs, and control the condition effectively. If the clinical examination suggests high blood pressure, the patient should follow the doctor’s instructions and take active treatment to avoid damage to the quality of life.
