Experts noted that high heart rate in middle age increases the risk of premature death by half. They have not yet been able to name the exact reasons for this connection, and noted that monitoring the change in heart rate helps to know how high the risk of developing cardiovascular diseases is in humans.

Scientists from Sweden conducted a study in which they found out: if a pulse is 75 beats per minute at a middle-aged person, then his risk of early death from various diseases is twice as high.

Experts recalled that a person’s heart rate varies at different ages. So, in 40-50 years old the norm is 65-90 beats per minute, in people over 51 years old – 60-90 beats per minute.

It is known that a small pulse (within the normal range, of course) indicates good physical fitness and a normal state of the cardiovascular system.

Diseases of the heart and blood vessels, according to researchers, is the main cause of death among the population of middle and old age.

Scientists decided to find out how changing heart rate affects health and whether it can be associated with the risk of early death.

The experiment was carried out in 1993, it was attended by 798 men born in 1943 in Sweden. They answered questions in the questionnaire and were surveyed.

The subjects were divided into four groups of heart rates: 55 or less beats per minute, 56-65 beats per minute, 66-75 beats per minute, and over 75 beats per minute.

Then the volunteers who were still alive were re-examined in 2003 and 2014 (654 and 536, respectively).

As a result, during the observation, 119 men died before the age of 71, 237 had cardiovascular diseases and 113 had ischemic heart disease. Since 2003, 111 participants in the experiment increased the pulse, 205 remained the same, and 338 decreased.

The researchers concluded that a heart rate of more than 75 beats per minute was associated with an increase in the risk of death from any cause by half, compared with a pulse of 55 beats per minute and below.
