We usually think that in a year, the incidence of coronary heart disease is the highest in the cold autumn and winter. And some studies have found that there is a high incidence of time of coronary heart disease in one day. The incidental possibility of coronary heart disease may increase from 6:00 pm, and 9 to 11 pm is the most likely to attack. Then why is it easy to attack at night?

1. Repletion

Modern people like to eat a big dinner, but in fact, this is not necessarily beneficial to health, but may be too rich, and cholesterol, fat, protein and other content is too high, causing the burden of the body. Angina, myocardial infarction and diabetes may have a close relationship with the long-term big dinner. If patients with coronary heart disease eat too much at night, gastrointestinal expansion and diaphragm lift will make it difficult to breathe. In order to digest too much food, more blood will be supplied to the digestive system, promoting the heart blood supply burden to increase, resulting in angina and myocardial infarction.

2. Agitation

After dinner, many people like to sit in the living room to watch TV. Sometimes the videos may relate to war or fighting scenes, which is too intense that, may cause sympathetic excitement and catecholamine substances increase in the blood, causing high blood pressure, coronary artery spasm, resulting in myocardial ischemia that also can cause angina pectoris or myocardial infarction.

3. Taking antihypertensive drugs before sleep

People's blood pressure will be lower at night, some patients with hypertension before going to bed will take antihypertensive drugs, so their blood pressure gets further declined, resulting in slow blood flow, heart blood deficiency, and myocardial infarction becomes easy to happen.

4. Decrease of air temperature in the evening

Winter night is cold, and it will increase the incidence of angina and myocardial infarction. Coldness can make sympathetic excitement and coronary artery spasm, aggravate coronary heart disease symptoms, inducing coronary heart disease attack. In summer, many people like to put the air conditioning on a whole night, while the body temperature regulation in sleep will be weakened, which may cause blood vessel contraction and even induce angina, etc. due to the low temperature.

Main measures to prevent the occurrence of coronary heart disease at night

1. Dinner should not be too full, generally about 80% of the satiety;

2. Appropriate restrictions of the TV time, while trying not to watch the tense and stimulant program;

3. Do not mention unpleasant things at night, so as not to affect personal emotions;

4. Ensure a quiet and comfortable sleep environment, in nocturnal sleep, patients with coronary heart disease accompanied by angina can choose 10 to 15 degrees tilted bed, that is, to keep the upper part of the body high and the lower part low, or to make the head of bed higher 15 to 20 cm than the foot of the bed;

5. Try to keep warm when sleeping in winter, and adjust to appropriate temperature of air conditioners in summer before sleep;

6. Had better prepare emergency drugs in the head of bed in case of need.
