When myocardial ischemia eat gum can only play a certain auxiliary role, but can not play a decisive role. Myocardial ischemia generally suggests that because of coronary heart disease and lead to problems with the blood supply of the heart, so called myocardial ischemia, in the electrocardiogram can be reflected as some changes in the ST segment or T wave, as a diagnostic basis, if necessary, you can perform coronary angiography or coronary artery CTA to make a clear diagnosis. Myocardial ischemia is not entirely caused by anemia, but by the formation of plaque in the coronary arteries, coronary artery stenosis, resulting in a reduction in blood flow, corresponding to the myocardial cells of the heart ischemic manifestations. When myocardial ischemia occurs in patients, the treatment can only rely on nitrate drugs to dilate the coronary arteries and establish rich collateral circulation to supply the ischemic state of the ischemic region. Coronary stenting can also be considered to open up the blood vessels and improve the ischemia in the functional area after the blood flow is enriched, or coronary artery bypass grafting can be considered to complete the improvement of ischemia. Aspirin should also be used as an antiplatelet aggregation therapy to prevent the formation of blood clots that can block the blood vessels.
