Inclusion Criteria: * Aged 18 years and older, with no gender restrictions. Clinically suspected or confirmed cardiovascular disease (including but not limited to ischemic heart disease, non-ischemic cardiomyopathy, myocarditis, valvular disease, etc.), requiring a cardiac magnetic resonance (CMR) examination to determine the etiology or evaluate myocardial tissue characteristics. No contraindications to magnetic resonance examination, and able to cooperate with breath-holding instructions. Voluntarily participate in this study and sign a written informed consent form. Exclusion Criteria: * Absolute contraindications: Implantation of non-MRI compatible metallic foreign bodies (e.g., old pacemakers, implantable cardioverter-defibrillators \[ICD\], aneurysm clips, etc.). Relative contraindications: Severe claustrophobia, unable to complete the examination despite communication. Severe renal insufficiency. Special populations: Pregnant or lactating women. Presence of severe arrhythmias (e.g., persistent atrial fibrillation) leading to severely impaired magnetic resonance signal acquisition, rendering the image quality inadequate for diagnosis. Poor expected compliance: Unable to complete follow-up, or deemed unsuitable for enrollment by the investigator for other reasons.
