Lymphocytic Myocarditis and Cardiogenic Shock in Hawai'i: A Case Series.

Lymphocytic myocarditis is an inflammatory disease of the heart that may present in a myriad of fashions ranging from mild febrile illness to florid myocarditis and cardiogenic shock. Given its nonspecific clinical presentation, the diagnosis of lymphocytic myocarditis is often challenging. The authors describe four cases of lymphocytic myocarditis in young women who presented with cardiogenic shock. Two patients survived and two died. This presentation has not been seen previously in Hawai'i and the public awareness of this condition is critical. Early diagnosis and the prompt initiation of biventricular mechanical circulatory support appear to have been critical in improving patient survival.
