The remaining blood vessels are blocked and the blocked capillaries are opened. Only the blood in this capillary grows normally, but whether other capillaries need residual blood is more serious and narrow. If other capillaries have more severe stenosis, it will also cause discomfort to patients. Sometimes there will be another situation, that is, microangiopathy. According to the contrast examination, the capillaries are fine and not severely narrowed, but the patient only has the performance of insufficient blood supply to the heart, not caused by microvascular disease. Coronary stent surgery is particularly important for patients with coronary heart disease (coronary artery stenosis ≥75), especially in the treatment of acute myocardial infarction, which can quickly open capillaries, repair cardiovascular blood supply and reduce the damage to the heart caused by insufficient blood supply. Clinically, we often encounter some patients who have undergone stent surgery complaining of chest tightness, shortness of breath, breath holding and other heart discomfort.
I want to know the reason why this happened. There are many reasons for heart discomfort after coronary artery surgery, and according to the questioner, the blood condition has improved very well after surgery, so there is no problem of restenosis after stent implantation. Today, let's find out why people with good blood condition after stent implantation still have heart discomfort. Ophthalmologists believe that if you feel very anxious, especially worried about the recurrence of myocardial infarction, it is necessary for you to receive psychological counseling to relieve your stress. The most common complications of myocardial infarction are short-term and long-term myocardial infarction complications. The most common manifestations of these symptoms are tingling in the precordial region or behind the sternum, sharp needle-like pain, or squeezing-like dull pain, which is sometimes mistaken for insufficient blood supply to the heart.
Subacute obstruction of capillaries represents the termination of myocardial blood supply. When the blood supply to nerve cells is cut off for one to three hours, permanent myocardial necrosis will occur. The longer the duration, the wider the scope of ischemia and the larger the area of myocardial necrosis, which means that the atrophic heart loses the function of aggregation and left ventricle. Therefore, even after cardiovascular stent treatment, there may be the possibility of heart function decline, that is, energy failure, and the common symptom is poor breathing after exercise. Insufficient blood supply to the heart. Coronary artery lesions may be three-stage. Although the blocked capillary is opened, there may still be residual small occupying lesions in other capillaries. If left untreated, patients may still have symptoms of obstetric angina pectoris. In addition, some patients with coronary heart disease are likely to be depressed, which will lead to a series of uncomfortable symptoms. Generally speaking, if you have symptoms of discomfort, you should seek medical advice in time to avoid the possibility of organic diseases.
