What should I do if I encounter such a situation? Acute attack: If you have an acute attack of angina after coronary intervention, stay sedated, stop all activities and rest in place. Immediately take 1 sublingual nitroglycerin tablet or 10 quick-acting heart pills. If the effect is not good, it should be taken every 5 minutes. If it is not effective even after 3 times, you may have an acute myocardial infarction and should immediately call “120” or “999” and go to the hospital as soon as possible. If you take the medication on your own, you should also go to the hospital to review the coronary angiogram as soon as possible. If the symptoms of angina pectoris are similar to those before surgery, the possibility of in-stent restenosis should be considered. If the symptoms are different from those before surgery, there may be a new coronary lesion. Before an important event: Before an important event, patients often experience elevated blood pressure and increased heart rate due to mental stress. To avoid the resulting angina, patients may take an additional 2-4 tablets of cardiac pain and half or one tablet of betalactone before an important event, depending on the blood pressure and heart rate at that time. If there is still an angina attack, rest in place and immediately take sublingual nitroglycerin or quick-acting heart pills. If the medication provides rapid relief, you can finish your business and then seek medical attention and review the coronary angiogram. If the attack is more severe than before, with sweating and panic, stop all activities and seek medical attention quickly. Travel: After coronary intervention, patients should bring their own emergency medicine box (nitroglycerin, quick-acting heart pills, etc.) and daily oral medicine, especially aspirin and clopidogrel, which should not be forgotten after intervention. When you travel, your diet is often irregular, but you must take your medication on time. If you have an angina attack that cannot be relieved by oral medication, you should immediately go to the nearest local hospital and take a nitroglycerin every 5 minutes on the way, or if you have a fast pulse (>70 times/minute) you can take or chew a piece of betalactone orally. If the acute attack of angina is well controlled by drugs and does not recur, you can go home and be hospitalized nearby to review coronary angiography. If angina is frequent or acute myocardial infarction occurs, you should immediately go to the nearest hospital with interventional conditions to actively control the condition and avoid possible dangers on the way home. Couple life: Couple life is very physically demanding. After intervention, if there is no restenosis of the stent and no new lesions in the coronary arteries, etc., normal couple life should not be affected. However, patients should proceed at their own discretion according to their conditions. If patients are worried about inducing angina, they can take anti-cardiac pain and/or betalactone beforehand, which will be effective in preventing angina attacks. Cold, fever, diarrhea: There is no conflict between current post-coronary intervention medications and anti-cold medications, antipyretics and medications for diarrhea in general. However, patients should be aware that blood volume is often insufficient during cold, fever and diarrhea, and patients should reduce or stop antihypertensive drugs according to the blood pressure at that time to avoid excessive blood pressure reduction. However, beta-blockers such as betalactam and atenolol should not be discontinued as much as possible. Other examinations such as MRI: After coronary intervention, patients are generally not affected by other examinations, but for special examinations such as MRI, it is recommended that patients should be examined 3 months after the intervention. Before having other tests, patients should inform their doctors that they are taking aspirin, clopidogrel, statins and other medications after the intervention. Patients with coronary artery disease should inform the surgeon of their past medical history before undergoing other procedures so that the surgeon can weigh the pros and cons. Anticoagulants such as aspirin and clopidogrel should be discontinued prior to general surgical procedures to avoid intraoperative hemorrhage. However, patients who are within 3 months after bare metal stent placement or within 1 year after drug stent placement, discontinuing the above drugs can induce in-stent thrombosis, causing acute myocardial infarction and threatening the patient’s life. Therefore, post-interventional patients should try not to undergo surgical procedures during this period. If surgery is necessary, aspirin and clopidogrel can be discontinued for 5-7 days under close supervision in hospital and subcutaneous injection of low molecular heparin can be applied at the same time, but there is still a possibility of myocardial infarction. Trauma: Trauma often triggers angina pectoris due to factors such as pain and stress, and the treatment medication is the same as in an acute attack, but trauma may lower blood pressure due to blood loss, so the amount of nitroglycerin contained should be reduced as appropriate. The most common problem encountered in trauma is bleeding. If the bleeding is localized on the body surface, compression may be applied to stop the bleeding and anticoagulants such as aspirin and clopidogrel should not be discontinued. However, if internal bleeding or intracranial bleeding is suspected, aspirin and clopidogrel must be stopped and hospitalized as soon as possible under close observation.
