On average, blood pressure is 15% lower at night than during the day. If with the help of some trick you measure the pressure at night, and it is not going to decrease there, that this is a bad sign. This is even worse than if it jumped during the day.
Even if the pressure was only slightly increased during the day, then such a lack of a night fall immediately increases the chance of getting heart failure later or something else bad.
It is not clear exactly why the pressure refuses to drop at night. It is suspected that it could be due to kidney problems or melatonin.
In short, when cardiologists began to understand the ups and downs of blood pressure at night, they tried to rectify the situation. Since people are rarely able to maintain their pressure with one pill, it was decided to drink a second or third before going to bed.
The results of this intervention were strange. Some researchers swore that the evening pill reduced the risk of heart death and other unpleasant events by 50%. Other scientists were surprised and objected that such good results, in principle, cannot be obtained in scientific research. But they still haven't figured out who is right and who is wrong.
Since initially there was a suspicion of kidney problems in such people, it became a good form for patients with increased arterial pressure and chronic kidney disease to move from morning to evening any of the three drugs to choose from: an inhibitor an angiotensin-converting enzyme like lisinopril or an angiotensin receptor antagonist like losartan, or long acting a calcium antagonist like amlodipine.
