Heart failure, mortality rate rises, the most suitable is 60 beats/min
Peking University First Hospital Cardiology Deputy Chief Physician Chen Erdong
"In a person's life, the number of beatings of the heart is limited, and the sooner people jump, the sooner they fail." Although such rumors are sometimes sensational, heart rate is indeed dangerous. Recently, the Journal of the American Medical Association The subspecialty of the cardiology published a study that observed that observations of community groups showed that heart rate increased 5 times per minute, the risk of heart failure increased by 13%, the risk of death increased by 13%, the most appropriate heart rate was 60 times/ Minute.
There have been many studies in the past on the relationship between heart rate and mortality rate, especially heart rate and cardiovascular and cerebrovascular diseases. For example, in 2014, the Framingham Study, known for its rigorous follow-up and complete data, released the 'heart rate' The conclusion is that the faster the heart rate is, the higher the risk of cardiovascular and cerebrovascular diseases will be. With every beat of the heart, there will be a blood flow pulse and blood vessels. The passive elastic force is a shock to the whole body's arteries. Under the action of various forces, the more heartbeats, the greater the damage to the arteries, and the more prone to atherosclerosis and endothelial injury. In addition, heart rate is a common result of the regulation of the human nervous system and the endocrine system. The increase in heart rate may be manifested by various pathological processes such as hyperactive sympathetic nervous system and excessive secretion of catecholamine hormones. These factors are hypertension, arteriosclerosis, heart failure and other diseases. An important mechanism in the development. Decreasing heart rate is the most important therapeutic goal. Research has confirmed that using drugs reduces the heart rate of heart failure patients by 10 beats/min, and the risk of death within 3 years can drop by 11%.
For certain groups of people, such as coronary heart disease, heart failure patients, heart rate should be controlled as much as 60 beats per minute. For the majority of healthy people, as long as the heart rate is in the normal range of 60 to 100 beats per minute, there is no problem. At the same time, control diet, lose weight, Increased aerobic exercise, etc., also have the effect of reducing the resting heart rate. Both healthy and cardiovascular and cerebrovascular patients should adhere to such a lifestyle.
