Former U.S. President Bill Clinton underwent coronary artery bypass surgery for coronary heart disease, and a leading medical newspaper listed the medications Clinton must take daily after the surgery, including beta-blockers. Clinton, who has often been exposed as having affairs with women, may be concerned by this. This is because the main adverse effect of beta blockers is that they can make men impotent and seriously affect a man’s sexual performance. The suave man has become a question mark in people’s minds as to whether he will remain as good as ever after the surgery. Heart bypass surgery is medically known as coronary artery vascular bypass grafting, or coronary artery bypass surgery for short. Coronary heart patients have atherosclerotic plaque in their coronary arteries, making the lumen narrow, making it difficult for blood flow to supply the distal myocardium through the stenosis, causing myocardial ischemia and hypoxia, resulting in palpitations, shortness of breath, posterior sternal pain and other angina symptoms, as well as arrhythmias, heart failure or myocardial infarction, and possibly ventricular wall tumors, septal perforation or mitral valve insufficiency due to myocardial infarction. Coronary artery bypass grafting is to reconnect the large blood vessel with the distal coronary artery by using another autologous blood vessel of the patient to cross the stenosis of the coronary artery, just like building a bridge to the heart, so that the blood can be resupplied to the distal ischemic myocardial tissue through this bridge to improve the ischemic state of the myocardium and achieve the purpose of treating coronary heart disease. After the symptoms of angina pectoris appear, coronary heart patients should seek medical help in time to do electrocardiogram, lipid examination, etc. If necessary, dynamic electrocardiogram or stress electrocardiogram should be done, and other tests such as echocardiogram and radionuclide myocardial imaging are helpful for diagnosis. To confirm the diagnosis, coronary angiography is required to provide a reliable basis for the indications for surgery. If the coronary angiogram determines the presence of stenosis, coronary artery bypass surgery must be considered. Patients need to undergo a physical examination before surgery to find out whether there are other physical problems, such as whether the patient has hypertension, diabetes, ulcer disease, etc., and whether the function of the lungs, liver, kidneys and other organs is normal. Of course, some patients are worried that they still need to take some drugs such as beta-blockers after surgery, and they are worried that such drugs will affect their sexual function and their virility will no longer. If the patient’s surgery is successful, there is no need to take as many allopathic drugs such as beta-blockers after surgery as before surgery. Moreover, the effect on sexual function is a not very common side effect of beta-blocker use, and it is entirely possible that Clinton will still be able to move around his social circle with grace and style, leaving behind many affairs. As for how to prevent restenosis of the bypass vessel or the rest of the blood vessels, it is necessary to control the risk factors that cause atherosclerosis, and doctors will advise patients to take aspirin-like antiplatelet drugs for life to prevent the restenosis of the bypass vessel due to atherosclerosis.
