心血管风险评估

最后更新：2023年08月31日

接口能力

本接口可通过捕捉慢病人群的心电特征，结合基础生理数据和部分症状指标来综合评估其未来三年内冠心病、脑卒中（中风）、心梗的发病风险。

请求方法

HTTP方法： POST
请求URL：http://api.amsu-new.com/amsu-analysis/v2/health/cvdr/results/
数据提交方式：multipart/form-data

Header参数：

字段 类型 描述
Authorization Bearer Token 构造方式为Bearer+(空格)+(Access Token)

Body参数：

字段 类型 必传 范围 描述
height Integer 是 90 - 240 身高，单位：cm
weight Float 是 30.0 - 200.9 体重，单位：kg
age Integer 是 20 - 90 年龄
gender Integer 是 0 - 1 性别，男1女0
htn Integer 是 0 - 1 高血压确诊情况，确诊1未确诊0
dm Integer 是 0 - 1 糖尿病确诊情况，确诊1未确诊0
sbp Integer 是 75 - 240 收缩压
symptom Array of Integer 是 1, 2, 3, 4, 5, 6, 7 临床症状，列出所有已出现的症状编号（请见下方表格）
disease Array of String 是 J45, G43, G47, R05, R07, R53 确诊疾病，列出所有已确诊疾病的ICD-10编码（请见下方表格）
ecg_file File 是 *.ecg 二进制心电文件，以.ecg作后缀名，尺寸限制 100M 以内（约55小时离线数据）。数据将按照 小端序 2字节short型被解析，可使用 心电图查看工具 观察您的文件是否能正确解析
model String 是 online、offline 心电记录模式，通过蓝牙采集的心电数据为online，在AMSU设备中存储的心电数据为offline
device String 是 V6、S1 心电设备类型，对应蓝牙协议中「Device Information」-「Model Number」里包含的开发代号，心电衣（带）主机对应代号为V6，心电贴对应代号为S1

提示

若 model 为 online ，请在构造心电文件时用您自定义的信息（或任意值）填充前256个字节作为头部，若不构造头部，则文件中前1~2秒的心电数据不会参与分析。

症状编号：

编号 描述 编号 描述 编号 描述
1 头晕头痛 4 心悸胸闷 7 水肿
2 恶心呕吐 5 呼吸道出血
3 呼吸异常 6 四肢麻木

ICD-10疾病编码:

编码 描述 编码 描述 编码 描述
J45 哮喘 G47 睡眠障碍 R07 咽痛或胸痛
G43 偏头痛 R05 咳嗽 R53 不适和疲劳

返回参数

字段 类型 描述
id Integer 本次分析的标识
chd Float 三年期冠心病患病风险（概率）
cva Float 三年期脑卒中（中风）发病风险（概率）
ami Float 三年期心梗发病风险（概率）

正确返回示例：

HTTP状态码：200

{
    "id": 459,
    "chd": 0.119,
    "cva": 0.103,
    "ami": 0.213
}
错误返回示例：

HTTP状态码不为200

{
    "error": {
        "code": "ECG.INVALID_DATA",
        "msg": "ECG data cannot be analyzed normally, which may be due to wrong format or poor signal quality."
    }
}

错误码

HTTP状态码 错误码 说明
422 ECG.INVALID_DATA 无法从心电数据中有效识别出R波，此错误的可能原因有：1. 心电文件格式出错；2.心电数据未正常采集；3.心电数据质量过差

另请参见 公共错误码
