To find out when and how to die is partly very frightening and often you do not want to know exactly. On the other hand, exactly this information could contribute to that longer life through medical help is possible.
Researcher of University of Gothenburg (Sweden) have based on the resting pulse rate Determined how long a person still has to live. A pulse of 75 beats per minute (BPM) in persons of middle age, therefore, at the risk of one premature death out.
Retirement: 798 men were examined between 1943 and 2014
The English trade journal Open heart of British Medical Journal published the results of the Swedish researchers. They examined the influence of altered heart rate on the risk of previous death in a total of 798 men, all of whom were born in 1943. At the beginning of the 1993 study, subjects (all aged 50 and over) completed a questionnaire on their lifestyle, current stress and any family history of heart disease. In addition, they had to undergo a medical examination in which the resting frequency was measured. Based on this, the men were divided into different groups. In 2003 and 2014, the investigations took place again.
In the course of the study, a total of 119 participants died before their 71st birthday. 237 men developed cardiovascular disease, with 113 participants suffering from coronary heart disease. (The coronary artery disease is a damage to the blood vessels, which are responsible for the oxygen and nutrient supply of the heart.)
Now, comparing the different resting heart rates, the 21-year study concludes that middle-aged people with a heart rate of 55 bpm ("beats per minute") or below have higher life expectancies. By comparison, people with a resting heart rate of 75 bpm or more die twice as often within the next two decades. According to the researchers, at 55 bpm each additional resting heartbeat per minute is associated with a three percent higher risk of dying.
Stable frequencies have a lower risk of heart disease
Among the men studied who had a stable frequency between 1993 and 2003, the risk of developing cardiovascular disease within the next eleven years was 44 percent lower, compared to other subjects who experienced an increase in heart rate with increasing age who demonstrated.
In addition, it was found that men with a BMP of over 55, more frequent smokers, were sedentary and stressed. They also often suffer from typical risk factors for heart disease, such as hypertension or obesity.
The resting heart rate indicates the beats of the organs per minute, if the body is not particularly strained. The normal value is between 50 and 100 strokes. Low heart rates indicate a healthy cardiovascular system and general fitness.
The study is just an observational study and suggests a specific age group. The results can therefore not be related to the general public.
