  • Summary

  • CardioNerds (Dr. Rick Ferraro and Dr. Dan Ambinder) join Dr. Sri Mandava, Dr. David Meister, and Dr. Marissa Donatelle from the Columbia University Division of Cardiology at Mount Sinai Medical Center in Miami. Expert commentary is provided by Dr. Pranav Venkataraman. They discuss the following case involving a patient with cardiac sarcoidosis presenting as STEMI: A 57-year-old man with a history of hyperlipidemia presented with sudden onset chest pain. On admission, he was vitally stable with a normal cardiorespiratory exam but appeared in acute distress and was diffusely diaphoretic. His ECG revealed sinus rhythm, a right bundle branch block (RBBB), and ST elevation in the inferior-posterior leads. He was promptly taken for emergent cardiac catheterization, which identified a complete thrombotic occlusion of the mid-left circumflex artery (LCX) and large obtuse marginal (OM) branch, with no underlying coronary atherosclerotic disease. Aspiration thrombectomy and percutaneous coronary intervention (PCI) were performed, with one drug-eluting stent placed. An echocardiogram showed a left ventricular ejection fraction (EF) of 31%, hypokinesis of the inferior, lateral, and apical regions, and an apical left ventricular thrombus. The patient was started on triple therapy. A hypercoagulable workup was negative. A cardiac MRI was obtained to further evaluate non-ischemic cardiomyopathy. In conjunction with a subsequent CT chest, the results raised suspicion for cardiac sarcoidosis with systemic involvement. In view of a reduced EF and significant late-gadolinium enhancement, electrophysiology was consulted to evaluate for ICD candidacy. A decision was made to delay ICD implantation until a definitive diagnosis of cardiac sarcoidosis could be established by tissue biopsy. The patient was started on HF-GDMT and discharged with a LifeVest. Close outpatient follow-up with cardiology and electrophysiology was arranged.

Pearls - Cardiac Sarcoidosis Presenting as STEMI Cardiac sarcoidosis can present with a variety of symptoms, including arrhythmias, heart block, heart failure, or sudden cardiac death. Symptoms can be subtle or mimic other cardiac conditions. Conduction abnormalities, particularly AV block or ventricular arrhythmias, are common and may be the initial indication of cardiac involvement with sarcoidosis. The additive value of Echocardiography, FDG-PET, and cardiac MR is indispensable in the diagnostic workup of suspected cardiac sarcoidosis. Specific role of MRI/PET: Both cardiac MRI and FDG-PET provide a complementary role in the diagnosis of cardiac sarcoidosis. Cardiac MRI is an effective diagnostic screening tool with fairly high sensitivity but is limited by its inability to decipher inflammatory (“active” disease) versus fibrotic myocardium. FDG-PT helps to make this discrimination, refine the diagnosis, and guide clinical management. Ultimately, these studies are most useful when interpreted in the context of other clinical information. Primary prevention of sudden cardiac death in cardiac sarcoidosis focuses on risk stratification, with ICD placement for high-risk patients. For patients awaiting definitive diagnosis, a LifeVest may be used as a temporary measure to protect from sudden arrhythmic events until an ICD is placed. Notes - Cardiac Sarcoidosis Presenting as STEMI 1. Is STEMI always a result of coronary artery disease? By definition, a STEMI is an acute S-T segment elevation myocardial infarction. This occurs when there is occlusion of a major coronary artery, which results in transmural ischemia and damage,
