Outside the indoor the temperature difference is big, easy to initiate coronary disease

　　In the summer the outdoor heat, in the room the air conditioning is cool, this kind of relapse from arrives hotly coldly, from Leng Daore the environmental variation, to the cardiovascular patient is extremely disadvantageous. Dr. Zhang Jian minister pointed out that cardiovascular disease and the temperature relations are very close. When hyperpyrexia, will increase the blood vessel blood stream quantity, will increase the heart pressure; But works as the temperature while cold, will have caused the blood vessel to contract correspondingly. If now hot and now cold, blood vessel's force contraction can cause in the coronary artery the mottling which forms to pull pulls the breakage, causes the thrombus, stops up the blood vessel, thus initiation cardiac arrest. Therefore, turns on the air conditioning not to be able the underheating, as soon as moves take the body slightly perspires as well, causes the environment which places maintains the relatively constant temperature as far as possible.

　　The indoor air pollution, easy to initiate the heart failure

　　The air conditioning room quite seals up, the indoor air pollution, the bacterium increases, if is in this kind of environment for a long time, easy to reduce in blood's oxygen content, suffers from the respiratory infections, this is especially dangerous to the heart function not entire patient, has the suggestion heart failure danger.

　　Causes cold cold, easy to initiate the rheumatic heart disease

　　The weather is summer burning hot, the people attire were few, has neglected to the joint the protection, if the long time blew the air conditioning, easy to suffer cold's attack, laid down the rheumatic heart disease's cause of disaster. In addition, the long time blows the air conditioning also very easy cold, enlarged has contracted the rheumatic heart disease's risk.

　　The aggravation blood pressure fluctuation, easy to initiate the angina pectoris and the arrythmia

　　In July, our country's many places are in the rainy season, the barometric pressure are low, the temperature is high, sultry, the moist environment is extremely easy to induce coronary disease. Dr. Zhang Jian minister stressed that if contracts hypertension's person long time to blow the air conditioning again, is very easy to cause the blood vessel to contract fiercely, the aggravation blood pressure's fluctuation, causes the blood pressure control not to be steady, causes the blood vessel lumen narrowly even to stop up, causes the cardiac muscle ischemia oxygen deficit, affects the heart function even to cause the sudden death, but may also display for symptoms and so on angina pectoris, arrythmia.

　　Obviously, summer blows the air conditioning, although cool comfortable, actually easy to initiate the cardiac arrest, the heart failure, the rheumatic heart disease, the angina pectoris, the arrythmia and so on many kinds of heart diseases. Then, blows when the air conditioning how can avoid initiating heart disease? Had heart disease or just completed heart surgery's person whether could blow the air conditioning? In view of these common questions, Dr. Zhang Jian minister has also made the detailed explanation.

　　Blows when the air conditioning how to avoid initiating heart disease?

　　Dr. Zhang Jianqing: Must prevent blows the air conditioning initiation heart disease, must pay attention to the following several spots.

　　1. pays attention to the surge chamber the temperature. Indoor temperature take 25~27℃ as suitable, do not be lower than 20℃.

　　more than 2. the windowing air changes, maintain the indoor air are fresh, one day should better maintain the room windowing ventilates 2~3 times. Generally the air conditioning opens 1~3 hours later must close down, evening sleeps when cannot turn on the air conditioning all night.

　　3. when goes out on the body perspires are many enters air conditioned room, should immediately take off has the perspiration fluid wet clothes, and dries on body's perspiration water as soon as possible.

　　4. the attention suitable supplement moisture content, drinks some weak teas, do not drink the ice water.

　　5. cleans the air conditioning frequently.

　　6 may take some preventive medicines suitably.

　　Human who has heart disease summer can blow the air conditioning?

　　Dr. Zhang Jianqing: Generally speaking, so long as the trouble is not the serious heart disease, is also may blow the air conditioning. Is worth paying attention, coronary disease patient, has the cardiac arrest, the heart to fade, or has the chest stuffily and so on oxygen deficit symptom patients, not blow the air conditioning suitably.
