1.What do you mean by coronary circulation?
A: Coronary circulation, that is, the blood circulation constituted by the arteries and veins that nourish the heart itself. The coronary circulation is the shortest circulation in the body circulation. The blood in the coronary vein mainly flows back to the right atrium through the coronary sinus, and the coronary artery starts from the root of the aorta, which has higher pressure and faster flow rate, and the anastomotic branch between the coronary arteries is relatively small and thin.
2.What is the heart rate of a normal person?
A: The average heart rate of a healthy adult in a quiet state is about 75 beats per minute, and the fluctuation range of normal adult heart rate is 60-100/min. The heart rate of women is faster than that of men, and the heart rate can increase during physical activity and mental excitement. Women’s heart rate is faster than men’s heart rate, but everything is relative, for example, people who often engage in heavy physical labor or physical exercise have a slower heart rate, which can be less than 60 beats per minute, but this can never be said to be a pathological state, and should be considered comprehensively.
3.How to detect heart disease early?
A: When the following phenomena occur in life, it is recommended to have a heart examination in order to detect heart disease early so that effective measures can be taken.
(1) Palpitations, fatigue, shortness of breath or feeling of breathlessness during physical activity.
(2) Sudden onset of retrosternal pain or chest tightness and pressure during exertion or stress.
(3) Pain in the left chest accompanied by sweating or pain radiating to the shoulder, arm and neck.
(4) Rapid, slow, short or irregular pulse.
(5) Sudden awakening during sleep or nightmares, palpitations, chest tightness, and breathlessness, and the need to sit up for a while to get better.
(6) Difficulty in breathing, chest tightness or chest pain during sexual intercourse.
(7) Palpitations, chest tightness or chest pain during a full meal, cold, smoking, or watching a stressful movie or TV.
(8) Feeling chest tightness, breathlessness and insufficient air especially easier than others in public places or meeting places.
(9) Palpitations and shortness of breath when going upstairs more easily than before or than others.
(10) Sudden palpitations, dizziness, blackness in front of the eyes, and a feeling of falling down.
(11) Children are less active than children of their age, or they feel palpitations, shortness of breath, and weakness during activities, or they have blue lips during activities.
(12) Palpitations and fatigue even after doing some light daily work after catching a cold, or feeling shortness of breath when walking slightly fast.
(13) Sudden chest discomfort and fainting on the floor, or a feeling of “dying” immediately.
(14) Difficulty in breathing at night when the pillow is low, and need to lie on a high pillow.
(15) Swelling of the lower extremities.
(16) Hypertrophy and deformation of the ends of the fingers or toes.
(17) Abnormal color of the face, lips and nails, such as cyanosis or dark red.
(18) Abnormal sound of heartbeat at rest, or tremor when touching the heart area on the anterior chest wall with the hand.
(19) Palpitations, dizziness, shortness of breath or swelling during pregnancy.
(20) Left shoulder pain that does not heal for a long time.
4.Which seven contraindications for heart patients?
A: (1) A contraindication to rapid weight loss. Weight loss too quickly, resulting in a large amount of protein consumption and muscle tissue reduction, resulting in the decline of myocardial tissue, inducing heart failure.
(2) Two avoid full meals. Three meals are too full, the stomach wall expansion, will make the lung pressure, resulting in increased cardiac metabolism, easy to induce the cause of myocardial infarction.
(3) Three avoid frequent night. The United States Boston Women’s Hospital, a study data show that heart patients are at risk of getting up in the middle of the night.
(4) four avoid refusing fat. University of London nutritionist Sanders research shows that if heart patients consume fish fat twice a week, their mortality rate is 30% lower than patients who restrict all fat and eat only higher fiber foods. Therefore, heart patients in the three meals a day appropriate arrangements of fish, poultry food, help heart recovery.
(5) Five avoid canola oil. Canola oil contains 40% of erucic acid, heart patients will thicken the blood vessel wall after eating, heart fat accumulation, aggravating the disease.
(6) six avoid morning running. Japanese sports medicine experts found that early morning jogging on the heart can cause undue pressure, so should take a walk, practice gas and other ways.
(7) seven avoid drinking alcohol, including drinks containing alcohol, there is a risk of causing myocardial infarction.
