The importance of the preoperative nutritional status of cardiothoracic surgical patients in determining outcomes is demonstrated and discussed. Demographic, anthropometric, and biochemical changes in patients undergoing cardiothoracic surgery increase the importance of identifying those at risk for postoperative complications resulting from malnutrition. The interrelationships of chronic heart failure, cardiac cachexia, nutritional status, and nutritional support are identified and emphasized. The complexities of myocardial energetics and metabolism are outlined together with the nutrient needs for patients undergoing cardiac, pulmonary, or other intrathoracic operative procedures.
本文论述并强调了心胸外科患者术前营养状况对手术结果的重要性。接受心胸外科手术的患者存在人口统计学、人体测量学和生物化学变化，这增加了识别因营养不良而导致术后并发症风险的重要性。本文还明确并强调了慢性心力衰竭、心脏恶病质、营养状况和营养支持之间的相互关系。本文还概述了心肌能量学和代谢的复杂性，以及接受心脏、肺部或其他胸腔内手术的患者的营养需求。
