          Abstract

          The clinical and imaging features of cardiac sarcoidosis (CS) and giant cell myocarditis (GCM) are occasionally indistinguishable. This is a case of heart block and ventricular tachycardia where cardiac MRI, fluorodeoxyglucose positron emission tomography (FDG-PET) and biopsy revealed intermediate clinicohistologic phenotype between CS and GCM. This highlights gaps in the management of overlap conditions.

          Underlying causes and long-term survival in patients with initially unexplained cardiomyopathy.

          D Clemetson, G. Michael Felker, R Thompson … (2000)
          Previous studies of the prognosis of patients with heart failure due to cardiomyopathy categorized patients according to whether they had ischemic or nonischemic disease. The prognostic value of identifying more specific underlying causes of cardiomyopathy is unknown. We evaluated the outcomes of 1230 patients with cardiomyopathy. The patients were grouped into the following categories according to underlying cause: idiopathic cardiomyopathy (616 patients), peripartum cardiomyopathy (51); and cardiomyopathy due to myocarditis (111), ischemic heart disease (91), infiltrative myocardial disease (59), hypertension (49), human immunodeficiency virus (HIV) infection (45), connective-tissue disease (39), substance abuse (37), therapy with doxorubicin (15), and other causes (117). Cox proportional-hazards analysis was used to assess the association between the underlying cause of cardiomyopathy and survival. During a mean follow-up of 4.4 years, 417 patients died and 57 underwent cardiac transplantation. As compared with the patients with idiopathic cardiomyopathy, the patients with peripartum cardiomyopathy had better survival (adjusted hazard ratio for death, 0.31; 95 percent confidence interval, 0.09 to 0.98), and survival was significantly worse among the patients with cardiomyopathy due to infiltrative myocardial disease (adjusted hazard ratio, 4.40; 95 percent confidence interval, 3.04 to 6.39), HIV infection (adjusted hazard ratio, 5.86; 95 percent confidence interval, 3.92 to 8.77), therapy with doxorubicin (adjusted hazard ratio, 3.46; 95 percent confidence interval, 1.67 to 7.18), and ischemic heart disease (adjusted hazard ratio, 1.52; 95 percent confidence interval, 1.07 to 2.17). The underlying cause of heart failure has prognostic value in patients with unexplained cardiomyopathy. Patients with peripartum cardiomyopathy appear to have a better prognosis than those with other forms of cardiomyopathy. Patients with cardiomyopathy due to infiltrative myocardial diseases, HIV infection, or doxorubicin therapy have an especially poor prognosis.

            A clinical and histopathologic comparison of cardiac sarcoidosis and idiopathic giant cell myocarditis.

            Yuji Okura, G.William Dec, Joshua Hare … (2003)
            The goal of this study was to determine the prognostic value of clinical data available at presentation and histology in cardiac sarcoidosis (CS) and idiopathic giant cell myocarditis (IGCM). The prognosis of patients with nonischemic cardiomyopathy is partly dependent on the histologic diagnosis. Survival in IGCM is poor. The prognosis of a histologically related entity, cardiac sarcoidosis (CS), is less well established, and the prognostic value of the distinction between CS and IGCM on endomyocardial biopsy (EMB) is unknown. We identified 115 patients from the Multicenter IGCM Registry with CS (n = 42) and IGCM (n = 73). We compared the clinical data for these two groups using Cox proportional-hazards models to assess the association between histologic diagnosis and survival. In order to determine whether histologic features could reliably differentiate these two entities, two cardiac pathologists semiquantitatively graded the inflammatory infiltrate components and compared the results between groups. Black race was more frequent in the CS group (31% vs. 4%, p < 0.0001). Syncope and atrioventricular block were also more frequently observed in CS than IGCM (31% vs. 5%, p = 0.0002 and 50% vs. 15%, p < 0.0001, respectively). Left-sided heart failure was more common in IGCM (40% vs. 64%, p = 0.013). In CS patients diagnosed by EMB, the five-year transplant-free survival after diagnosis was 69.8% versus 21.9% for IGCM (p < 0.0001, log-rank test). In multivariate models, presentation with heart failure predicted IGCM, and presentation with heart block or more than nine weeks of symptoms predicted CS. Eosinophils, myocyte damage, and foci of lymphocytic myocarditis were more frequent in IGCM, while granulomas and fibrosis were more frequent in CS. Transplant-free survival is better for patients with CS than for IGCM diagnosed by EMB. Presentation with heart failure predicted IGCM, and presentation with heart block or more than nine weeks of symptoms predicted CS.

              Manifestations and Outcome of Cardiac Sarcoidosis and Idiopathic Giant Cell Myocarditis by 25‐Year Nationwide Cohorts

              Hanna-Kaisa Nordenswan, Jukka Lehtonen, Kaj Ekström … (2021)
              Background Cardiac sarcoidosis (CS) and giant cell myocarditis (GCM) share many histopathologic and clinical features. Whether they are parts of a one‐disease continuum has been discussed. Methods and Results We compared medical record data of 351 CS and 28 GCM cases diagnosed in Finland since the late 1980s and followed until February 2018 for a composite end point of cardiac death, aborted sudden death, and heart transplantation. Heart failure was the presenting manifestation in 50% versus 15% ( P <0.001), and high‐grade atrioventricular block in 21% versus 43% ( P =0.044), of GCM and CS, respectively. At presentation, left ventricular ejection fraction was ≤50% in 81% of cases of GCM versus in 48% of CS ( P =0.004). The median (interquartile range) of plasma NT‐proBNP (N‐terminal pro‐B‐type natriuretic peptide) was 5273 (2782–11309) ng/L on admission in GCM versus 859 (290–1950) ng/L in CS ( P <0.001), and cardiac troponin T exceeded 50 ng/L in 17 of 19 cases of GCM versus in 48 of 239 cases of CS ( P <0.001). The 5‐year estimate of event‐free survival was 77% (95% CI, 72%–82%) in CS versus 27% (95% CI, 10%–45%) in GCM ( P <0.001). By Cox regression analysis, GCM predicted cardiac events with a hazard ratio of 5.16 (95% CI, 2.82–9.45), which, however, decreased to 1.58 (95% CI, 0.71–3.52) after inclusion of markers of myocardial injury and dysfunction in the model. Conclusions GCM differs from CS in presenting with more extensive myocardial injury and having worse long‐term outcome. Yet the key determinant of prognosis appears to be the extent of myocardial injury rather than the histopathologic diagnosis.
