Ventricular tachycardia (VT, a potentially fatal condition where the ventricle of the heart beats rapidly) superimposed on non-ischemic cardiomyopathy (NICM, a disease of heart with broad etiologies except coronary artery disease). This disease has been associated with inflammation in the heart. The purpose of this study is to assess the benefit of immunosuppressive therapy to suppress the VT, improve heart function, avoid invasive intervention and hospitalization. Positron Emission Tomography (PET) imaging shows inflammation in the heart. After enrollment, baseline tests (including physical exams, blood tests, genetic test, electrocardiography, echocardiography) will be done. Next, will be an 8-week medication regimen which contains either immunosuppressive drugs or standard GDMT without immunosuppressant medication. Some of the examinations will be repeated during the study to evaluate the treatment response and monitor any adverse events.
Ventricular arrhythmia (VT) is a well-established consequence in patients with non-ischemic cardiomyopathy (NICM). NICM is a broad category that includes a wide spectrum of causes, which may include: bacterial, viral toxin mediated and immune mediated and "unexplained" when coronary disease has been excluded. The pathophysiology of NICM is not well understood but inflammatory responses with macrophage recruitment during remodeling have been described. On the other hand, an infectious trigger i.e. myocarditis may be the inciting event for the development of cardiomyopathy. A previous study by T…
