If a patient has an abnormal diastolic blood pressure of 100 mmHg and a systolic blood pressure of 130 mmHg, he or she is considered hypertensive. It is recommended that the patient can first be treated with lifestyle interventions. If the patient is currently overweight or obese, it is not excluded that after weight loss exercise, it is likely that the blood pressure will return to normal accordingly, because blood pressure is often proportional to weight. If it is the first time that a patient finds his blood pressure so high, it is advisable to have ambulatory blood pressure monitoring to assess the overall blood pressure over 24 hours. If the patient’s blood pressure is still around this range after 1-3 months of lifestyle intervention, the treatment is currently focused on high diastolic blood pressure, and the preferred antihypertensive drugs are the pulmonary or sartan antihypertensive drugs, with representative drugs such as perindopril and telmisartan.
