Initiation and monitoring of immunosuppressive therapy | Identification and quantification of inflammation, including longitudinal follow-up |
Device therapy/implantable cardioverter-defibrillator | Identification of high-risk patients for sudden cardiac death beyond traditional markers (left ventricular ejection fraction) |
