纳入标准:

第一阶段:建立不同海拔高度人群的心血管健康状况队列数据库 研究人群:高原不同海拔干部群众,民族不限。 第二阶段:建立不同海拔人群心血管疾病发病及危险因素数据库 对于不同疾病的入选标准及数据采集要求如下:心血管疾病:a.冠心病:①既往冠脉造影或冠脉CT诊断史并提供依据,而并非是仅心电图异常②既往住院诊断冠心病;③对于高度疑似患者进行进一步检查。b.心力衰竭:心力衰竭属于心血管疾病患者的病理生理状态,而非一种疾病,心力衰竭的诊断需依靠超声心动图评价患者心脏收缩或舒张功能,而不能仅依靠患者的主诉或者生命体征,可以使用纽约心脏学会心功能分级、6分钟步行试验或者生活质量评分等评价患者心力衰竭严重程度;c.高血压①既往明确诊断高血压且正规服药者;②两次血压收缩压≥140mmHg和或舒张压≥90mmHg;d. 肺动脉高压①超声心动图:三尖瓣反流速度(TRV)>2.8m/s或肺动脉收缩压>35mmHg;②胸部CT:肺动脉高压征。 第三阶段:高原地区冠状动脉微循环的研究 纳入标准:1)年龄18-80岁;2)临床疑诊冠心病,拟进行冠脉造影检查;3)有清晰可供分析的冠状动脉造影影像。 第四阶段:采用代谢组学和蛋白组学研究冠心病、高血压发生机制的方法及流程 诊断为高血压、冠心病的患者。

Inclusion criteria

Stage 1: Establish a cohort database of cardiovascular health status of people at different altitudes. Study population: cadres and people at different altitudes of plateau, regardless of nationality Stage 2: To establish a database of cardiovascular disease incidence and risk factors at different altitudes The inclusion criteria and data collection requirements for different diseases were as follows: cardiovascular disease: a. Coronary heart disease: ① previous diagnosis of coronary artery disease by coronary angiography or coronary CT, other than ECG abnormalities; 3) further examination of highly suspected patients. b. Heart failure: Heart failure is a pathophysiological state of patients with cardiovascular disease, rather than a disease. The diagnosis of heart failure depends on the evaluation of systolic or diastolic function of the patient's heart by echocardiography, and can not only rely on the patient's complaints or vital signs. c. Hypertension ① Patients with a definite diagnosis of hypertension and regular medication; ② two blood pressure systolic blood pressure >=140mmHg and/or diastolic blood pressure >= 90mmHg; d. Pulmonary hypertension: ① Echocardiography: tricuspid regurgitation velocity (TRV) >2.8m/s or pulmonary artery systolic pressure > 35mmHg; ② Chest CT showed signs of pulmonary hypertension. Stage 3:Study of coronary microcirculation at high altitude Inclusion criteria: 1) Age of 18-80 years old; 2) Coronary angiography if clinically suspected CAD; And 3) clear coronary angiography images for analysis. Stage 4: Methods and procedures for studying the mechanisms of coronary heart disease and hypertension using metabolomics and proteomics Patients diagnosed with hypertension, coronary heart disease.

随机方法(请说明由何人用什么方法产生随机序列):

第一阶段:在西藏自治区下辖6个地级市,1个地区(8个市辖区,66个县),通过分层抽样方法共抽取2976名人员。 根据估算的每层所需最小样本量62个,4个样本区域各调查744个体,每个区域按工作年限6个层(当地工作年限6个时间段(1-5年,6-10年,11-15年,16-20年,21-25年,>25年)各层124个体,6个层内按不同性别分为2组(男、女)每组62例。 第三阶段:根据血红蛋白浓度(HGB)与AMR对患者进行分组。1)根据HGB(g/L) 分组:正常 vs. 升高 (升高人群中按HGB三分位分组);2)根据AMR分组:<250vs. ≥250。 第四阶段:以不同海拔、不同居住年限人群诊断冠心病患者为研究对象。A:冠心病组(N=60例),符合冠心病国际诊断标准。B组:健康对照组(N=30例)。

Randomization Procedure (please state who generates the random number sequence and by what method):

Stage1: A total of 2976 subjects were selected by stratified sampling method from 6 prefecture-level cities and 1 district (8 municipal districts and 66 counties) in Tibet Autonomous Region. According to the estimated minimum sample size of 62 for each stratum, 744 individuals were investigated in each of the 4 sample areas, and 124 individuals were investigated in each stratum according to the working years (6 periods of local working years (1-5 years, 6-10 years, 11-15 years, 16-20 years, 21-25 years, > 25 years). Within the 6 layers, they were divided into 2 groups (male and female, 62 cases in each group). Stage 3:Patients were grouped according to hemoglobin concentration (HGB) and AMR. 1) According to HGB (g/L) Grouping: normal vs. elevated (tertiles of HGB in those with elevated levels); 2) grouping according to AMR: <250vs. >=250. Stage 4:Patients with CHD diagnosed at different altitudes and living years were selected as the research objects.A: Coronary heart disease group (N=60), which met the international diagnostic criteria for coronary heart disease. Group B: healthy control group (N=30).
