Can poison cause myocardial ischemia

summary

Myocardial ischemia will seriously affect the normal function of the heart, there are many diseases will cause myocardial ischemia. At present, there are many reasons for myocardial ischemia. Some patients are very curious about whether poisoning can cause myocardial ischemia. Let's talk about whether poisoning can cause myocardial ischemia.

Can poison cause myocardial ischemia

First: myocardial ischemia is a pathological state in which the blood perfusion of the heart is reduced, resulting in the decrease of oxygen supply to the heart, abnormal myocardial energy metabolism, and unable to support the normal work of the heart. Coronary heart disease is the most important and common cause of myocardial ischemia. With the improvement of people's living standards, the prevalence of myocardial ischemia in China is increasing year by year, which has become a common and frequently occurring disease in the elderly.

Second, there are many causes of myocardial ischemia, such as decreased blood pressure, decreased aortic blood supply, and coronary artery occlusion, which can directly lead to decreased blood supply to the heart; valvular heart disease, changes in blood viscosity, and myocardial lesions can also reduce blood supply to the heart. The most common cause is coronary atherosclerosis, followed by inflammation (rheumatic, syphilitic, Kawasaki disease and vascular occlusive vasculitis), spasm, embolism, connective tissue disease, trauma and congenital malformation.

Third: the energy needed for heart activity is almost completely provided by aerobic metabolism, so even when it is quiet, the blood oxygen uptake rate of the myocardium is also very high (about 70%). Under normal circumstances, the body can adjust itself to make the blood supply and demand relatively constant, so as to ensure the normal work of the heart. Epidemiological studies have found that the important risk factors associated with atherosclerosis are hyperlipidemia, hypertension, diabetes, smoking, obesity, less physical activity, old age and so on.

matters needing attention

The above introduction is about the cause of myocardial ischemia, and some symptoms, we can see that it is generally caused by coronary heart disease and some other heart diseases. Although it is said that the poison will have a great impact on the human body and is life-threatening, it can not be confirmed by research that the poison can cause myocardial ischemia.
