Correct sleeping posture will also reduce the occurrence of coronary heart disease. Sleeping posture will have an effect on the heart. The sleeping position we often adopt is supine with straight legs and bent legs on the left and right sides. The best position is to lie down with knees bent on the right side, because the pressure on the heart is small, just in line with the old saying "lying like a bow". Patients with coronary heart disease have poor heart function, and the onset time of coronary heart disease is at night, so patients with coronary heart disease should choose the correct sleeping position. Patients with moderate or severe angina pectoris of coronary heart disease, or patients with cardiac insufficiency of coronary heart disease, should choose high head and low feet and high head and chest pad to reduce blood return to the heart and reduce the burden on the heart, so it is beneficial to the condition. If you use a bed that can swing, you can swing the bed appropriately according to the patient's feeling, generally 10- 15 degrees. This can also reduce the incidence of coronary heart disease.
