Every afternoon blood pressure suddenly increased without energy, to meet the diagnostic criteria for hypertension, you can follow the doctor’s instructions to take antihypertensive drug treatment. Clinically normal adults in a quiet state, the normal range of blood pressure in the systolic blood pressure 139mmhg / diastolic blood pressure 89mmhg, if more than 140mmhg systolic blood pressure and/or diastolic blood pressure 90mmhg after the diagnosis of hypertension. A physiologic increase in blood pressure usually occurs between 4:00 pm and 8:00 pm, so care needs to be taken to monitor blood pressure. It is recommended to monitor the blood pressure 3 times not on the same day and then take the average value for evaluation. If the average value exceeds the systolic blood pressure of 140mmhg and/or diastolic blood pressure of 90mmhg, then the diagnostic criteria of hypertension are met, and antihypertensive drugs can be taken for treatment as prescribed by the doctor. Usually antihypertensive drugs are: 1. Diuretics, such as furosemide, hydrochlorothiazide, etc.; they can reduce the extracellular volume and lower the peripheral vascular resistance, so as to achieve the effect of lowering blood pressure. 2. β-blockers, such as metoprolol, etc.; they can inhibit myocardial contractility and slow down the heart rate, thus playing a role in lowering blood pressure. 3. Calcium channel blockers, such as nifedipine and amlodipine, can inhibit the entry of extracellular calcium ions into the vascular smooth muscle cells and reduce the contraction response of the resistance vessels, so as to achieve the effect of lowering blood pressure. Usually, after a sudden increase in blood pressure in the afternoon, it is recommended to consult the cardiovascular medicine department in time, after the doctor’s comprehensive assessment of the condition for treatment.
