Aging causes the heart to lose weight, pumping weak blood

Scientists have evidence to explain why aging itself is an important factor in heart failure. According to the results of the study, the older the person becomes, the lighter the heart and the slower the heart muscle.

Since 2000, the team from Johns Hopkins University, USA, has used many methods to monitor heart structure and function to evaluate the smallest heart changes of 5.004 people, both male and female.

female, 45 - 84 years old, from many different ethnic groups in North America.

At the time of the study, all of these people had no symptoms of heart disease. One of the above methods is to use cardiac images taken with high-tech magnetic resonance imaging (MRI) to look at changes in heart muscle that correspond to the heartbeat.

Research results show that each year passes in the elderly, myocardial contractility slows from 2% to 5%, blood volume is reduced by about 8 ml by heart and myocardial volume decreases by 0.3. g.

Up to now, 79 people have suffered from congestive heart failure.

Female doctor Susan Cheng, the lead researcher, said: 'The effect of aging in heart failure among healthy, multi-racial people is a concern, but heart failure is not just arising. from known causes, such as high blood pressure '.

Ms. Cheng said that the finding could lead to diagnostic tests to determine the heart of someone who is aging faster than others, in order to apply preventive or lifestyle changes to do so. Slow, or even exclude, effects that are harmful to the heart.

The study emphasizes changes in heart function and heart structure when people age naturally , similar to the cases that are common in older adults such as arteriosclerosis, bone weakness due to calcium loss, and impairment. decreased kidney function.

According to Associate Professor Joao Lima of Johns Hopkins University, this finding is particularly significant for people who are entering the age of 60 - ages with signs of heart disease. In the US alone, there are currently 5 million people affected by some symptoms of congestive heart failure, such as difficulty breathing and fatigue.

He emphasized: 'Doctors and patients need to be aware that such changes may be accelerated by risk factors, but may also be slowed by adopting a healthy and productive lifestyle. Satisfactory medical care '.

The results of this study were published on November 4 at the annual meeting of the American Heart Association, in Orlando, Florida.
