It is estimated that about 3.5 million people die from cardiovascular diseases in China every year, accounting for 41% of the total causes of death and topping the list of various diseases. As a common pathological state of cardiovascular disease, myocardial ischemia can bring serious adverse effects to the heart and body and is very harmful, so it is important to ensure timely and standardized treatment to avoid missing the best time for disease treatment. Here’s how to recognize myocardial ischemia and see how Panax ginseng works on it.
Understanding myocardial ischemia
Myocardial ischemia is a pathological state in which the blood perfusion to the heart is reduced, resulting in reduced oxygen supply to the heart and abnormal myocardial energy metabolism, which cannot support the normal work of the heart. The energy required for cardiac activity is almost entirely provided by aerobic metabolism, so even when it is quiet, the myocardial blood oxygen uptake rate is high (about 70%). Under normal circumstances, the body can promote relatively constant blood supply and demand through its own regulation to ensure the normal work of the heart. When there is an imbalance of blood supply and demand to the myocardium for some reason, it constitutes myocardial ischemia in the true sense.
Causes of myocardial ischemia
Many people do not know what causes myocardial ischemia? Next, Master Yun popularizes the causes of myocardial ischemia, which are mainly the following three causes.
Coronary artery atherosclerosis
The common cause of myocardial ischemia is coronary atherosclerosis, because the generation of coronary atherosclerosis is not conducive to the myocardial blood supply in the ischemic area, which will increase the risk of myocardial infarction, accelerate the process of heart failure and easily induce myocardial ischemia. Epidemiological studies have found that important risk factors associated with atherosclerosis, such as hyperlipidemia, hypertension, diabetes, smoking, obesity, increased homocysteine, and low physical activity, can also trigger myocardial ischemia.
Age Factors
Aging of blood vessels (which include capillaries or arteries of the heart) or thickening of vessel walls in the elderly can lead to poor blood flow, causing insufficient blood supply to the heart and predisposing to myocardial ischemia.
Other causes
Next are various factors such as inflammation (rheumatic, syphilitic, Kawasaki disease and vaso-occlusive vasculitis), spasm, embolism, connective tissue diseases, trauma and congenital malformations.
Clinical manifestations of myocardial ischemia
The incidence of myocardial ischemia is high in the elderly, and the symptoms are not particularly obvious at the early stage of the disease, so it is easy to be ignored by patients, thus delaying the treatment and leading to deterioration of the disease, which brings serious threat to physical and mental health. Therefore, it is necessary to know the symptoms of myocardial ischemia.
The symptoms of myocardial ischemia are.
1.Dull pain in the posterior sternum or precordial area or tightness-like pain when exertion or mental tension occurs and radiates to the left shoulder and left upper arm for 3 to 5 minutes, which can be relieved by itself after rest and accompanied by heavy sweating.
2. Chest tightness, palpitations and shortness of breath occur during physical force activities, and are relieved by themselves at rest.
3.Sore throat and burning and tightening sensation related to exercise, toothache, etc.
4.Chest pain and tightness appear after a full meal, cold, or drinking alcohol.
5.When sleeping with a low pillow at night, you feel chest tightness and breathlessness, and you need to lie down with a high pillow to feel comfortable; when sleeping or lying down during the day, you suddenly have chest pain, palpitations and difficulty in breathing, which can be relieved by sitting up or standing up immediately.
6, panic, chest tightness, shortness of breath or chest pain when straining to defecate.
7.Sudden bradycardia, decreased blood pressure or syncope.
8.Tiredness without any cause that can be explained, lack of energy.
9.Patients without typical symptoms only feel upset stomach, nausea, or toothache, cervical pain, etc.
The effect and principle of Panax ginseng on myocardial ischemia
The main active ingredient of Panax notoginseng is total saponin, which can inhibit platelet aggregation, reduce blood viscosity, increase blood flow in coronary arteries, reduce myocardial load and lower myocardial oxygen consumption.
Meanwhile, a spectroscopic study on the protective effect of Panax notoginseng on myocardial ischemia in China Modern Applied Pharmacology showed that Panax notoginseng total saponin can significantly improve the ischemic state of human body, reduce the scope of myocardial ischemia, reverse the left ventricular diastolic dysfunction in patients with exertional angina and restore it to normal, and have good preventive and adjuvant therapeutic effects on myocardial ischemia.
Warm Tips
In addition to early medical diagnosis of myocardial ischemia, dietary treatment in life is also very important, so what fruit is good for myocardial ischemia?
1.Kiwifruit
Kiwifruit is known as the king of fruits, its high vitamin content, but also has antioxidant effect, for myocardial ischemia has a good preventive effect.
2, walnuts
Walnuts are rich in unsaturated fatty acids, which can prevent the symptoms of myocardial ischemia brought about by atherosclerosis.
3.Hawthorn
Hawthorn is rich in vasodilator substances, which are good for strengthening the heart muscle and regulating blood lipids.
