Current concepts in the management of stable ischemic heart disease and acute coronary syndrome in patients with hemophilia.

Coronary artery disease (CAD), including stable ischemic heart disease (SIHD) and acute coronary syndrome (ACS), remains the leading cause of death in the US and one of the primary modalities used in the treatment of CAD is percutaneous coronary intervention (PCI). Despite the potential benefits of PCI in high risk CAD patients, the risk of hemorrhage presents a dilemma in the treatment of patients with hemophilia A and B. In an attempt to provide guidance on the management of SIHD and ACS in patients with hemophilia, we present the case of a patient with moderate hemophilia B and ACS who subsequently underwent PCI followed by a review of the associated literature.

New-Onset Myocarditis in an Immunocompetent Adult with Acute Metapneumovirus Infection.

Introduction. A number of viruses have been implicated in viral myocarditis; however, there has been no previous report of human metapneumovirus (hMPV) causing this condition. Discovered in 2001, hMPV is typically associated with upper respiratory illness, mainly affecting children. Case Presentation. We report the case of a 25-year-old man with acute systolic heart failure from viral myocarditis secondary to the hMPV. The patient was initially admitted to the general medical ward but developed increasing oxygen requirements resulting in transfer to the cardiac intensive care unit. Cardiac magnetic resonance imaging was used to help confirm the diagnosis. He was treated with intravenous diuretics, and afterload and preload agents, and he was subsequently discharged home after seven days of hospitalization. Discussion. hMPV is typically a respiratory pathogen; however, it was associated with in myocarditis in our patient. Due to the recent ability to detect this virus, we may see more cases of this, particularly during peak months of infection. Conclusion. This is the first case description of myocarditis associated with hMPV infection.
