Description for medicine or protocol of treatment in detail:

 

纳入标准:

(1)年龄18-80岁;
(2)有典型心绞痛症状(CCS分级Ⅱ级以上);
(3)CCTA提示冠脉主支狭窄40-90%(因CCTA相比冠脉造影可能会高估狭窄程度);
(4)拟入院行冠状动脉造影;
(5)经知情同意参加本项研究并提供本人资料。

Inclusion criteria

(1) Age 18-80 years old;
(2) With typical symptoms of angina pectoris (CCS grade II or above);
(3) CCTA indicates 40-90% stenosis of the main coronary artery (because CCTA may overestimate the degree of stenosis compared with coronary angiography);
(4) Intending to be admitted to the hospital for coronary angiography;
(5) Participate in this study with informed consent and provide personal information.

排除标准:

(1)急性心肌梗死; (2)陈旧性心肌梗死; (3)复杂心律失常,如频发性房性早搏、室性早搏、心房颤动、心房扑动等; (4)PCI/CABG术后; (5)先天性心脏病史; (6)明确诊断的心肌病; (7)冠脉起源或发育异常; (8)CCTA提示多支病变(≥2支冠脉主支狭窄>50%); (9)CCTA提示左主干病变(LM狭窄>50%); (10)冠脉重度钙化(CCTA钙化积分>400); (11)起搏器术后及植入药物泵患者; (12)躯干部位有钢板、钢钉等金属植入物; (13)患有幽闭恐惧症,无法在密闭环境静卧2分钟的患者; (14)其他原因研究者认为不适合入选的受试者; (15)冠脉最重狭窄<40%; (16)冠脉最重狭窄≥90%(接受介入治疗); (17)冠脉狭窄介于70-89%的患者由术者决定直接介入治疗或者行FFR评估; (18)受试者拒绝接受FFR检查。

Exclusion criteria:

(1) Acute myocardial infarction; (2) Old myocardial infarction; (3) Complex arrhythmias, such as frequent atrial premature beats, premature ventricular beats, atrial fibrillation, atrial flutter, etc.; (4) After PCI/CABG; (5) History of congenital heart disease; (6) Definitely diagnosed cardiomyopathy; (7) Abnormal origin or development of coronary arteries; (8) CCTA indicates multi-vessel disease (≥2 main coronary artery stenosis >50%); (9) CCTA shows left main lesion (LM stenosis > 50%); (10) Severe coronary artery calcification (CCTA calcification score > 400); (11) Patients with pacemaker surgery and drug pump implantation; (12) There are metal implants such as steel plates and nails in the trunk; (13) Patients who suffer from claustrophobia and cannot lie still for 2 minutes in a closed environment; (14) Subjects considered by the investigators to be unsuitable for inclusion for other reasons; (15) The most severe stenosis of coronary artery <40%; (16) The worst stenosis of coronary artery ≥ 90% (received interventional therapy); (17) For patients with coronary artery stenosis between 70-89%, the operator decides to directly intervene or perform FFR evaluation; (18) The subjects refused to accept the FFR examination.

Target condition (The target condition is a particular disease or disease stage that the index test will be intended to identify. Please specify the characteristics in detail; the population should has a complete spectrum and good representative):

Coronary angiography shows that the most severe coronary artery stenosis is between 40-89% and the patients with FFR<0.8

容易混淆的疾病人群(即与目标疾病不易区分的一种或多种不同疾病,应避免采用正常人群对照的病例-对照设计):

冠状动脉造影显示冠状动脉最重狭窄在40-89%之间,FFR≥0.8的患者

例数:

Sample size:
