Correlation Between Coronary Artery and Brain Study

Patients: Patients with heart disease, such as coronary heart disease, atrial fibrillation or flutter, cardiac insufficiency, etc. were included. And collect the patient's brain MRI data simultaneously. To explore the relationship between embolic properties and cerebral embolism, the relationship between cardiovascular and cerebrovascular diseases and cognitive dysfunction, and also comparison of changes in cardiocerebral structure and function before and after intervention with risk factors. Imaging protocols: Brain magnetic resonance acquisition: Use a 3.0T magnetic resonance scanner for imaging, and the acquisition coil uses a dedicated brain coil. The scan sequence includes routine T1WI, T2WI, FLAIR, and other sequences. If necessary, further patient functional magnetic resonance examinations such as BOLD, 3D T2FLAIR, 3D FSPGR-T1WI, 3D pCASL, DTI, and 3D SWI are performed. Cardiac magnetic resonance acquisition: cardiac and coronary CTA, cardiac and coronary MRA; Myocardial perfusion magnetic resonance imaging, etc. Treatment: Intervention treatment for risk factors Follow-up: Baseline (MRI+clinical evaluation); 3-months, 6-months,1-year (MRI+clinical evaluation).
