If patients want to determine their blood pressure fluctuations, they can go to the hospital for 24-hour ambulatory blood pressure monitoring to determine the type. If there is no condition, please ask your family to take a blood pressure test every two hours at night to determine whether you need to take medicine at night. The high blood pressure with a decrease of more than 10% at night (from 22 p.m. to 6 p.m. the next day) is called spoon type. This kind of hypertension patients really should not take antihypertensive drugs at night, or 2 hours later to reach the drug efficiency period, which may lead to a significant drop in blood pressure, affect the blood supply of heart, brain, kidney and other organs, slow blood rheology, insufficient blood supply to brain tissue, and increased blood coagulation. Especially in the elderly with atherosclerosis, the intima of the blood vessels is rough, which is more likely to form thrombus, block the heart and brain vessels and lead to ischemic stroke, which leads to the insufficiency of myocardial blood supply and leads to angina pectoris and myocardial infarction. For this kind of patients, it is recommended that the last antihypertensive drug be arranged 3-4 hours before going to bed every day.
Part of the patients with hypertension do not fall at night or the extent of decline is very small. This type of blood pressure fluctuation is called non spoon type, especially in patients with severe hypertension, heart, brain, kidney and other organ damage, or severe insomnia and some patients with sleep apnea syndrome. This part of patients blood pressure fluctuated less or disappeared in the day and night. The blood pressure kept at a high level at night, which would make the heart, brain and kidney vessels in a long-term state of overload. If you dont take antihypertensive drugs at night, your blood pressure cant be effectively controlled, which is easy to cause chronic damage, even lead to heart disease and stroke. It is necessary for such people to take antihypertensive drugs at night.
Even though the blood pressure shows a normal law of decreasing at night, it may temporarily increase in some special cases, such as emotional excitement, staying up late, insomnia, etc. At this time, the blood pressure should be measured in time and compared with that at night. If necessary, the antihypertensive drugs can be temporarily taken once, the dosage is half of the single time in the daytime.
Therefore, whether to take antihypertensive drugs at night cannot be generalized. There are great individual differences among different patients. In addition, the condition, course of disease, organ damage and complications are different. It is necessary to decide how to take antihypertensive drugs according to the specific situation, especially the change of blood pressure at night.
