title: Nitric oxide inhalation is useful in the management of right ventricular failure caused by myocardial infarction.
abstract: OBJECTIVE
  To describe hemodynamic improvement in a patient treated with nitric oxide (NO) inhalation in the management of right ventricular failure caused by myocardial infarction.
  
  
  METHODS
  Case report.
  
  
  METHODS
  An intensive care unit of a university hospital.
  
  
  METHODS
  A 66-yr-old man with severe right ventricular failure caused by acute myocardial infarction.
  
  
  METHODS
  Nitric oxide inhalation through a ventilator circuit.
  
  
  RESULTS
  The patient complained of chest pain. When myocardial infarction was diagnosed, he underwent percutaneous transluminal coronary angioplasty and percutaneous transluminal coronary recanalization, but they were not effective. We instituted intra-aortic balloon pumping and brought the patient to the intensive care unit (ICU). Even with high-dose inotropic support, his hemodynamics deteriorated gradually. On the patient's seventh day in the ICU, we started NO inhalation at 5-10 ppm in an attempt to relieve his right heart failure. Immediately after NO inhalation was started, his hemodynamics improved significantly, and we could wean the patient from intra-aortic balloon pumping. NO inhalation was continued for 9 days and was successfully discontinued without circulatory deterioration. He was discharged from our hospital uneventfully.
  
  
  CONCLUSIONS
  Nitric oxide inhalation improved hemodynamics in our patient with right ventricular failure after myocardial infarction. Our report suggests that a clinical trial of NO treatment for severe right ventricular failure caused by myocardial infarction is warranted.
