| dc.description.abstract | Coronary artery bypass grafting (CABG operation), which is also called coronary artery bypass grafting, referred to as coronary bypass or bypass, is a relief of angina and reduce the risk of death from coronary heart disease operation. The bypass artery or vein were derived from the patient’s own (internal mammary artery, radial artery, right gastroepiploic artery, saphenous vein). The operation bridges the blood vessel on coronary artery to get around the coronary atherosclerotic stenosis, improve coronary perfusion, and increase myocardial oxygen supply. This operation is usually performed in cardiac arrest, requiring the use of cardiopulmonary bypass support; and bypass surgery can also be performed on the beating heart, the so-called “off-pump” operation. Same as other operation, CABG gets risk of coronary artery bypass grafting. For example, the Postoperative delirium, some research shows that delirium is a group of syndrome, also known as acute brain syndrome, the expression is recognizant obstacle, behavior no chapter, no purpose, inability to concentrate. To be strict, delirium is not a disease but clinical syndrome caused by a variety of reasons. In this paper we use MMSE to evaluate the intelligent condition of patients after operation, then analysis the relationships between MMSE and the condition of patients themselves or the ICU. | en_US |
