Normal blood pressure during the day and high blood pressure in the evening is a form of hypertension. Normal blood pressure has two peaks in the morning and two peaks in the afternoon, and a trough in the early hours of the night, in the form of a spoon shape. In patients with hypertension, the spoon shape tends to disappear, and in some cases there is an inverse spoon shape, meaning that the blood pressure is normal during the day and significantly higher at night. In patients with hypertension, the rhythm of circadian fluctuations in blood pressure is altered. Patients with hypertension should be treated with antihypertensive medications and lifestyle interventions to prevent cardiovascular and cerebrovascular events through blood pressure control.
