Keywords: percutaneous coronary intervention care
Coronary heart disease refers to coronary artery due to the occurrence of severe atheroma hyperplasia or merge thrombus formation causing luminal obstruction caused by coronary insufficiency, myocardial ischemia or infarction of a heart attack. According to the different circumstances of blocked blood vessels, angina pectoris, myocardial infarction, arrhythmias, heart failure and even cardiac arrest and other clinical manifestations of coronary heart disease.
Any physical activity or emotional chest men Tong, rest a few minutes after remission should do coronary angiography to determine whether the presence of coronary artery disease, and provide the basis for the next treatment. Coronary angiography is inserted into a special catheter through the femoral artery thigh or upper extremity of the radial artery puncture coronary openings, selectively injecting the contrast agent into the coronary artery, the recording developing process to whether the judgment coronary lesions.
Severe stenosis after coronary angiography confirmed presence of coronary transluminal coronary angioplasty called PTCA treatment, depending on the situation through the femoral artery or radial artery under X-ray fluoroscopy, the front end with a balloon catheter to the part of the coronary artery lesions, pressure filled balloon dilatation of the stenotic lesions, so as to achieve the purpose of improving myocardial blood supply and relieve symptoms. Stenosis restenosis after balloon dilation, 40% of the lesions occur, some patients with acute coronary occlusion lead to the onset of acute myocardial infarction or death happens, After the completion of the expansion of blood vessels, need to re-use coronary stent lesion permanent distraction. Implanted stenting to to reduce plaque tear collapse and acute occlusion, and to increase the safety of the operation, to reduce restenosis.
By family members and patients before surgery on the surgical consent signature, the surgery eve of prescription drugs and adequate rest, fasting on the morning of surgery, preoperative emptying urine. Surgery is equipped with a the angiography machine of DSA room, the patients simply lying on the operating table, and according to the doctor’s orders in a timely manner can adjust the breath. Patients themselves without feeling the pain, surgery, the doctor will be in the patient’s thigh roots or wrist, first made puncture local anesthesia, and there a variety of catheter insertion direct cardiac angiography or treatment of bleeding during surgery rarely, patients not feel the catheter movement within the body. In patients sometimes do angiography precordial discomfort or fever flu treatment (dilation of blood vessels or put a stent) may have a similar sense of the chest pain of angina pectoris. These are normal, but one has these feelings to the doctor immediately explained.
The patient should drink plenty of water discharged to facilitate contrast agent, within 24 hours, try not to eat a high-protein diet, the legs do not move as far as possible within 24 hours of surgery and whether the blood oozing own place to observe the puncture oppression. Postoperative sure was prescribed oral anticoagulant drugs such as aspirin, aspirin, pay attention to the follow-up of white blood cells. Generally one week after the normal activities January avoid doing MRI follow-up after discharge back to the hospital according to the doctor’s medical advice. Must continue to control the predisposing factors for coronary heart disease, and the treatment of related diseases.
