The correct expression for high pressure 150 and low pressure 80 is 150 mmHg systolic and 80 mmHg diastolic. high pressure 150 and low pressure 80 is considered mild hypertension. Mild hypertension needs to be treatable by improving lifestyle, treating comorbidities, and controlling risk factors. If this does not work for six months, then drug therapy needs to be initiated. Hypertension is diagnosed if systolic blood pressure is ≥140 mmHg and/or diastolic blood pressure is ≥90 mmHg when blood pressure is measured once a day, respectively, over a three-day period without antihypertensive medication. Patients with a previous history of hypertension who had received regular blood pressure-lowering treatment were diagnosed with hypertension despite a blood pressure <140/90 mmHg. Hypertension was further classified into three levels according to the level of elevated blood pressure. Grade I hypertension (mild) was 140~159 mmHg systolic and 90~99 mmHg diastolic; Grade II hypertension (moderate) was 160~179 mmHg systolic and 100~109 mmHg diastolic; Grade III hypertension (severe) was ≥180 mmHg systolic and ≥110 mmHg diastolic. High pressure 150 low pressure 80 Referring to the above diagnostic criteria. It can be seen that 150 meets the systolic range of 140~159mmHg for class I hypertension, but 80 is lower than the diastolic range of 90~99mmHg. Like this case, the level of hypertension is judged by the highest degree of blood pressure, therefore, high pressure 150 and low pressure 80 can be judged as mild hypertension. The treatment of mild hypertension should not be taken lightly, as it can still be aggravated and cause target organ damage if not properly controlled.
