One night a few days ago, a patient who had surgery with me 1 year ago called me and in the past few days, he started to feel an angina attack again. After coming to me for a dual source 64-row spiral CT, he found that, except for the anterior descending internal mammary artery bridge, which had the usual flow, several other bridges had varying degrees of stenosis, with the most severe one reaching 90%. Worse still, two of the vessels that had not been stenosed had stenoses approaching 70%. This patient was not too old, in his 50s, and the postoperative period was not too long. Although venous vascular bridges do not have as high a rate of long-term patency as internal mammary artery bridges, it is not too common to see this degree of stenosis so soon. Due to the distance from us, he did not come back for review except for 1 month postoperatively. After asking him more about his treatment and life during the year, we finally realized how the problem had arisen. He was a diabetic patient, and postoperative blood glucose control has a very important impact on the outcome of treatment. But unfortunately, except for going to the clinic once in a while to test his blood glucose, he never tested his blood glucose on weekdays and just took oral hypoglycemic drugs according to the regimen he was discharged from the hospital. Worse still, he had never exercised dietary control either, and a review after hospitalization revealed that his fasting blood glucose had exceeded 10 μg/ml without his knowledge. Poor control of blood glucose was only one of the reasons for his condition. After the operation, he did not take any of all the medications for coronary artery disease except aspirin and Polivir. This was bad enough that, on this review, his coronary vessels were much more calcified than they had been a year earlier. Of course, this is “thanks” to his high salt, high fat diet and a pack of cigarettes a day. The same situation is not limited to bypass patients; postoperative restenosis is more common in stented patients. Neither bare-metal nor drug-coated stents can completely solve the problem of in-stent restenosis. If in-stent restenosis is a technical problem that cannot be solved completely, the short-term development of new stenosis in other parts of the coronary arteries is largely related to the individual’s inability to standardize the use of medication and poor lifestyle habits. I know a patient who is a Muslim. The diet is beef and lamb, high fat content, plus he loves smoking and drinking. 2011, coronary blood vessels have problems, do a stent, quite good, angina symptoms no longer, happy to go home. In 2011, he had a stent done, which was very good, and he went home happily, but he came back a year later, saying that his angina had returned, the same as before. My first impression was that the stent was blocked. Then I had to have an angiogram. What was the result? The stent that was put in a year ago was fine, and the other vessel had a stenosis of more than 90%, whereas a year ago the stenosis was less than 70%. I told him when he was discharged, “If you don’t go home and change your habits of eating, drinking, smoking and drinking, you’ll have to come back to me next year.” It is difficult to change existing habits. Many people can tolerate the pain of surgery, but cannot make up their minds to change those bad habits. Many patients have the impression that coronary heart disease is cured after surgery. There are also many patients who ask me this way: “Director Shang, if I build the bridge, my coronary heart disease is cured, right? I will be able to do anything and everything, right?” In fact, I would always pour cold water on them. Whether it is stenting or bypassing the bridge, it only solves the problem of stenosis and cardiac ischemia that currently occurs in the coronary arteries, but the cause of coronary heart disease has not been removed. Therefore, after surgery is still a coronary heart disease patients, still need to strictly in accordance with the coronary heart disease for standardized treatment and review. In a word: the surgery cured the table, the original problem has not been solved. This may be a little discouraging to many patients who have had surgery and are preparing to have surgery, but in terms of the treatment of coronary heart disease, this is definitely a protracted battle. The idea that it’s all over in one fell swoop is difficult to realize at this point, and it’s also extremely harmful.
