Heart disease is a general term for heart disease, including rheumatic heart disease, congenital heart disease, hypertensive heart disease, coronary heart disease, and myocarditis.
Common complications: heart failure, pulmonary infarction, cerebral infarction, myocardial infarction, sudden death, pulmonary heart disease, multiple organ failure and so on. Room septal defect, ventricular septal defect, and patent ductus arteriosus are often prone to pneumonia, prone to heart failure, Fallot’s quadruple syndrome can often be complicated by cerebral thrombosis, brain abscess.
The items that should be checked during the physical examination of patients with heart disease include a medical examination, blood pressure, electrocardiogram, blood lipids, blood sugar, liver and kidney function, and blood routine.
From the perspective of environmental protection, all the sounds that affect people’s normal learning, work and rest are all people’s “unwanted voices” in some occasions, collectively referred to as noise. Such as the roar of the machine, the motor sound of various vehicles, the sound of whistling, the noise of people and all kinds of sudden sounds, etc., are called noise.
The range of noise impacts on people’s health can be said to be more and more extensive. A large amount of data available has already shown that not only serious damage to hearing, but also serious impact on people’s health.
In China, the relevant standards stipulate that residential area noise should not exceed 55 decibels during the day and 45 decibels at night. Some cities around the world have imposed restrictions on the noise generated by transportation.
In order to prevent noise, Professor Ma , a famous Chinese acoustician, has summarized and studied the various types of noise hazards and standards at home and abroad, and put forward three suggestions:
1 In order to protect people’s hearing and physical health, the allowable value of noise is in 75~90 decibels.
2 Guarantee conversation and communication. The allowable value of ambient noise is in 45~60 decibels.
3 For sleep time, it is recommended to decibel in 35~50.
1 30~40 decibel is the ideal quiet environment.
2 70 decibels can affect conversations.
3 Long-term living in an environment above 90 decibels, hearing can be severely affected and cause neurasthenia, headache, high blood pressure and other diseases.
4 If suddenly exposed to noise up to 150 decibels, the light tympanic membrane will rupture and bleed, and both ears will completely lose hearing; heart resonance leads to death.
All relevant factors were statistically analyzed, including age, gender, education level, lifestyle, community noise, airport and rail noise.The results showed a statistically significant correlation between the noise received by residents living in the community and the heart disease.
In the 2006 year, these researchers, from the experimental population, found that patients with cardiovascular disease who were first discovered by 1600 were added. There is a clear causal relationship between these noise exposures and cardiovascular disease.
