[Perioperative Management for Prevention of Cardiac Complications in General Thoracic Surgery]. Koike Terumoto,Tsuchida Masanori Kyobu geka. The Japanese journal of thoracic surgery For general thoracic surgeons, perioperative management for prevention of cardiac complications is important because patients undergoing general thoracic surgery often have risk factors for cardiac disease. Sever cardiac failure should be detected and treated prior to surgery, and coronary artery may be examined in patients with risk factors for ischemic heart disease. Pulmonary resection sometimes causes right-sided heart failure due to reducing pulmonary vascular bed. In high-risk patients for rightsided heart failure, pulmonary artery pressure monitoring by right heart catheterization should be considered in addition to blood pressure and central venous pressure monitoring, and precise fluid management is required. Because perioperatively occurred myocardial infarction is sometimes lethal, patients with preoperatively identified significant coronary artery stenosis, percutaneous coronary intervention or coronary artery bypass grafting should be considered although surgeons need to be careful for the timing of surgery and anticoagulant therapy. Even if patients have no typical symptoms, perioperative myocardial infarction can be diagnosed 12-lead electrocardiogram and serum biomarkers. Cooperation with cardiologists is necessary for the treatment of perioperative myocardial infarction. Although arrhythmia is one of the major complications after general thoracic surgery, arrhythmia with hemodynamic instability should be immediately treated. Early diagnosis and management of cardiovascular events can minimize the consequences of these complications.
