Abstract

Objective To explore the relationship between the body weight and the structure and function of the left ventricle in the elderly inpatients, in order to emphasize the importance of body weight in the health management for elderly patients. Methods A total of 152 elderly inpatients meeting the enrollment criteria and providing informed consent were consecutively recruited. The height, body weight, body mass index (BMI), liver and kidney function, glycosylated hemoglobin, blood lipid, blood uric acid and structure and function of left ventricular were measured by anthropometry, biochemical examination and echocardiography respectively. The clinical characteristics, metabolic parameters, structure and function of left ventricular were compared among the low/normal weight, overweight and obesity groups. The correlation between left ventricular diastolic dysfunction (E/A≤0.7) and the metabolic factors was analyzed. Results The incidences of lower/normal weight, overweight and obesity in elderly inpatients were 29.6% (45/152), 52.6% (80/152) and 17.8% (27/152) respectively. Compared with the lower/normal weight group, the level of systolic blood pressure, glycosylated hemoglobin(P=0.005), left atrial diameter(P=0.000), left ventricular posterior wall dimension(P=0.010), left ventricular diastolic diameter(P=0.010), left ventricular mass(P=0.000), relative wall thickness and septal thickness increased significantly in overweight and obesity groups (all P<0.05). A higher proportion of left ventricular diastolic dysfunction was observed in overweight and obesity groups in the patients aging 60-69 years (P=0.028). There was positive correlation between left ventricular diastolic dysfunction and BMI (P=0.022). Conclusions Overweight/obesity increases the risk of left ventricular diastolic dysfunction among elderly inpatients. The body weight management needs to be strengthened in health management for the elderly patients. Key words: Elderly inpatient; Body mass index; Left ventricle; Correlation

老年住院患者体重与左心室结构、功能的关系

目的探讨老年住院患者的体重与左心室结构和功能的关系，以强调体重在老年患者健康管理中的重要性。方法连续招募符合入组标准并提供知情同意书的152名老年住院患者。分别采用人体测量、生化检查和超声心动图测量身高、体重、体重指数、肝肾功能、糖化血红蛋白、血脂、血尿酸及左心室结构和功能。比较低/正常体重组、超重组和肥胖组的临床特征、代谢参数、左心室结构和功能。分析左心室舒张功能障碍（E/A≤0.7）与代谢因素的相关性。结果住院老年人低体重/正常体重、超重和肥胖的发生率分别为29.6%（45/152）、52.6%（80/152）和17.8%（27/152）。与体重较低/正常组相比，收缩压、糖化血红蛋白（P=0.005）、左心房直径（P=0.000）、左心室后壁尺寸（P=0.010）、左室舒张直径（P=0.010，超重组和肥胖组的相对壁厚和室间隔厚度均显著增加（均P<0.05）。在60-69岁的患者中，超重组和肥胖症组左心室舒张功能障碍的比例较高（P=0.028）。左心室舒张功能紊乱与BMI呈正相关（P=0.022）增加了老年住院患者左心室舒张功能障碍的风险。老年患者的健康管理需要加强体重管理。关键词：老年住院患者；体重指数；左心室；相关性

期刊介绍： The Chinese Journal of Clinical Nutrition was founded in 1993. It is the first professional academic journal (bimonthly) in my country co-sponsored by the Chinese Medical Association and the Chinese Academy of Medical Sciences to disseminate information on clinical nutrition support, nutrient metabolism, the impact of nutrition support on outcomes and "cost-effectiveness", as well as translational medicine and nutrition research. It is also a professional journal of the Chinese Medical Association's Parenteral and Enteral Nutrition Branch. The purpose of the Chinese Journal of Clinical Nutrition is to promote the rapid dissemination of knowledge on nutrient metabolism and the rational application of parenteral and enteral nutrition, focusing on the combination of multidisciplinary and multi-regional field investigations and clinical research. It mainly reports on nutritional risk screening related to the indications of parenteral and enteral nutrition support, "cost-effectiveness" research on nutritional drugs, consensus on clinical nutrition, guidelines, expert reviews, randomized controlled studies, cohort studies, glycoprotein and other nutrient metabolism research, systematic evaluation of clinical research, evidence-based case reports, special reviews, case reports and clinical experience exchanges, etc., and has a special column on new technologies related to the field of clinical nutrition and their clinical applications.
