Why does coronary heart disease recur after stent implantation?

In fact, surgical treatment only makes the infarcted blood vessels recanalize. If we don't change the unhealthy lifestyle and control the risk factors of cardiovascular diseases, there will still be the risk of recurrence. Experts remind that patients with coronary heart disease after stent implantation, besides taking medicine according to doctor's advice, reasonable diet and exercise can also reduce the recurrence rate and mortality rate of myocardial infarction. Symptoms of recurrence of coronary heart disease after stent implantation? Tell everyone.

Symptoms of recurrence of coronary heart disease after stent implantation

1, angina pectoris type: manifested as a feeling of squeezing behind the sternum, abdominal distension, accompanied by obvious anxiety, lasting for 3 ~ 5 minutes, often spreading to the left arm, shoulder, jaw, throat and back, and also radiating to the right arm. Sometimes it may involve coronary atherosclerotic heart disease.

2, myocardial infarction type: about a week before infarction, there are often premonitory symptoms, such as angina pectoris and slight physical activity at rest, accompanied by obvious discomfort and fatigue. During infarction, it is characterized by persistent intense pressure, tightness and even knife-like pain, which is located behind the sternum and often involves the whole chest, especially the left side. Some patients can radiate downward along the ulnar side of the left arm, causing tingling sensation in the left wrist, palm and finger hemp, and some patients can radiate to the upper limbs, shoulders, neck and mandible, mainly on the left side. The pain site is the same as the previous angina pectoris, but it lasts longer and the pain is heavier. Rest and nitroglycerin can't relieve it. Sometimes it is manifested as epigastric pain, which is easily confused with abdominal diseases. Accompanied by low fever, irritability, sweating, cold sweat, nausea, vomiting, palpitation, dizziness, extreme fatigue, dyspnea, and sense of dying, lasting for more than 30 minutes and often lasting for several hours. You should see a doctor immediately if you find this situation.

3. Asymptomatic myocardial ischemia: Many patients have extensive coronary artery obstruction but do not feel angina pectoris, and even some patients do not feel angina pectoris during myocardial infarction. Some patients have sudden cardiac death, which was discovered only after routine physical examination found myocardial infarction. Some patients underwent coronary angiography because of arrhythmia on ischemic electrocardiogram or positive exercise test. The probability of sudden cardiac death and myocardial infarction in these patients is the same as that in patients with angina pectoris, so we should pay attention to the usual heart health care. Sudden cardiac death may occur in seemingly healthy people. Here we mainly talk about a kind of coronary heart disease, called unstable plaque. Because coronary atherosclerotic plaque is very small and does not block blood vessels, there are no symptoms at ordinary times. However, the plaque will suddenly rupture, and a thrombus composed of platelets and red blood cells will be formed locally after rupture, which is very large, and the coronary artery will cramp and narrow, leading to severe ischemia. Then, a large area of myocardial infarction,

Matters needing attention

In addition to exercise intensity, there are four standards for the amount of exercise during the rehabilitation of patients with coronary heart disease. First of all, a little sweating during exercise and slight breathing acceleration will not affect the dialogue; Followed by the end of exercise, the heart rate recovered 5- 10 minutes after rest; Once again, I am relaxed and happy after exercise, and my appetite and sleep are good; Finally, there is no persistent fatigue and muscle aches. Patients with coronary heart disease should exercise in strict accordance with the above standards.
