Usually myocardial ischemia in pregnant women is not normal. Having myocardial ischemia in either a pregnant woman or another patient is not in itself a normal presentation. Pregnant women are more likely to develop myocardial ischemia in the late stage of pregnancy, mainly because the fetus is getting bigger in the late stage of pregnancy, which causes pressure on the lungs of pregnant women, leading to respiratory difficulties and insufficient supply of oxygen to the heart, which will trigger myocardial ischemia. Pregnant women may experience panic, dyspnea, shortness of breath and other symptoms. It is recommended that patients should pay more attention to rest in general, avoid exertion, stay up late, and relax more. When the uncomfortable symptoms attack can be combined with oxygen therapy, help to relieve the symptoms of discomfort in the precordial area. In addition, if all of the above methods are still unable to relieve the symptoms, it is recommended that pregnant women go to the hospital in a timely manner and follow the doctor’s instructions for treatment in order to avoid delaying the condition.
