Magnetocardiography in the Accurate Identification of Myocardial Infarction

Other illness

• Those who with acute or chronic respiratory diseases;
• Those who with endocrine diseases such as abnormal thyroid function;
• Those who with anemia or other blood diseases;
• Those who with connective tissue diseases (lupus erythematosus, rheumatoid arthritis, dermatomyositis, polyarteritis nodosa, etc.);
• Those who with malignant tumors;
• Those who with infectious diseases or infectious diseases;
• Those who with psychological or mental illness such as depression;
• Due to various reasons such as allergy to contrast agents, metal implants in vivo that are prohibited from performing 1.5T MRI (such as prostheses or steel plates implanted in orthopaedics, uterine contraceptive device) and other reasons, those who cannot or fail to cooperate with the corresponding research requirements.
  • For chest pain patients who will receive ECG, biomarkers, or non-invasive imaging examination:
• Patients with known structural heart disease such as cardiomyopathy and valvular disease;
• Patients with arrhythmias such as atrial fibrillation, supraventricular tachycardia, and atrioventricular block that have not returned to normal;
• History of other cardiovascular diseases such as pulmonary embolism and aortic dissection;
• Patients with connective tissue diseases (lupus erythematosus, rheumatoid arthritis, dermatomyositis, polyarteritis nodosa, etc.) combined with cardiac complications;
• Obvious abnormal thyroid function, severe anemia or other blood diseases and other diseases that obviously affect the circulating blood supply;
• Patients with malignant tumors;
• Acute diseases or critical illnesses in other systems, such as acute or severe respiratory diseases, abnormal liver function or renal function, etc.;
• Patients with infectious diseases or infectious diseases;
• Those who are unable or fail to perform magnetocardiography due to claustrophobia, physical impairment, etc.;

Other

• Those who with obvious abnormality of liver or kidney function;
• Those who are obese (BMI\>30kg/cm2) or underweight (BMI\<18kg/cm2);
• Those who with trauma or physical disability;
• Those who are professional athletes, pregnant or breastfeeding women, alcoholics;
• Those who are unable to perform magnetocardiography examination due to claustrophobia, etc., or those who fail to receive magnetocardiography examination;
• Obese (BMI\>30kg/cm2) or underweight (BMI\<18kg/cm2);
• Professional athletes, pregnant or breastfeeding women, alcoholics;
• Unable to or fail to cooperate with the corresponding research requirements.

• Age 18-79 years old;
• No history of cardiovascular disease (coronary heart disease, structural heart disease, arrhythmia, heart failure, stroke, pulmonary embolism, aortic dissection, etc.), no cardiovascular risk factors (hypertension, diabetes, hyperlipidemia). For people over 65 years old, those with hypertension or hyperlipidemia, but with well-controlled blood pressure and lipid levels, taking no more than 2 drugs, and echocardiography showing no left ventricular hypertrophy, can be included;
• The electrocardiogram is normal, and the cardiac ultrasound is basically normal in the past 1 year (mild valvular regurgitation can be included).
• Sign the informed consent.
• Age 18-79 years old;
• Those with chest pain symptoms, diagnosed or highly suspected by the attending doctor or above as stable angina pectoris (SA), unstable angina pectoris (UA), non-ST segment elevation myocardial infarction (NSTEMI), ST segment elevation myocardial infarction (STEMI), and plan to receive electrocardiogram, biomarkers (high-sensitivity cardiac troponin, etc), or non-invasive imaging (cardiac magnetic resonance or single-photon-emission tomography);
• Sign the informed consent.
