HF without OSA

The following data were collected at the first medical visit and during follow-up (1) echocardiography parameters, including left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume (LVEDD), left atria size (LA), interventricular septum thickness (IVS) and left ventricular posterior wall (LVPW), the ratio of early diastolic mitral in flow velocity (E) to early diastolic TDI annular velocityle’s (E/e’) , and calculated left ventricular mass index (LVMI); (2) N-terminal B-type natriuretic peptide (NT-proBNP); (3) Physical examination information and New York Heart Association (NYHA) functional class; (4) history of smoking and drinking; (5) drugs for heart failure, co-morbidities (cardiovascular, metabolic, and respiratory);

本数据集采集自患者首次就诊及随访阶段的数据，具体包含以下内容：(1) 超声心动图参数：包括左心室射血分数（left ventricular ejection fraction, LVEF）、左心室舒张末期容积（left ventricular end-diastolic volume, LVEDD）、左心房内径（left atria size, LA）、室间隔厚度（interventricular septum thickness, IVS）、左心室后壁厚度（left ventricular posterior wall, LVPW）、舒张早期二尖瓣血流速度（E）与舒张早期组织多普勒成像（TDI）环部速度（e’）的比值（E/e’），以及计算所得的左心室质量指数（left ventricular mass index, LVMI）；(2) N末端B型利钠肽原（N-terminal B-type natriuretic peptide, NT-proBNP）；(3) 体格检查信息与纽约心脏协会（New York Heart Association, NYHA）心功能分级；(4) 吸烟与饮酒史；(5) 心力衰竭用药情况及合并症（心血管、代谢及呼吸系统疾病）
