About this trial

This is a prospective clinical study aiming to investigate the efficacy of Magnetocardiography (MCG) in detecting myocardial ischemia in patients of a suspected non-ST-elevation-acute coronary syndrome (NSTE-ACS) by using Single photon emission computed tomography (SPECT) as the gold standard for determining the presence and severity of myocardial ischemia.

Eligibility criteria

Qualifiers

Age 18 years or older;

Patients with symptoms of myocardial ischemia such as angina pectoris, who have CAG showing <70% stenosis at the most severe site or CTA showing non-severe stenosis

Signed informed consent.

Disqualifiers

Patients with absolute or relative contraindications to SPECT-loaded myocardial perfusion, including acute myocardial infarction within 48 hours, significant left main coronary artery stenosis, bronchial asthma, and adenosine injection allergy;

Patients with Non-ischemic dilated cardiomyopathy, or hypertrophic cardiomyopathy, or moderate or severe valvular disease;

Patients with Hemodynamic instability (systolic blood pressure<90 mmHg, or who requires vasoactive drugs), or patients with tachyarrhythmia, Ⅱdegree atrioventricular block and above that have not returned to normal;

Patients who have severe renal abnormality with eGFR <30 ml/min, or patients who are on dialysis;
