Osborn wave in hypothermia from Vibrio vunificus sepsis unrelated to exposure.
A 58 year old man with history of cirrhosis presented with Vibrio vunificus sepsis. The patient developed multiorgan failure despite appropriate antibiotic therapy and fluid resuscitation. ⋯ Osborn wave is commonly seen in accidental hypothermia. Although sepsis is known to cause hypothermia, Osborn wave in sepsis is not widely appreciated.

Transient myocardial dysfunction after smoke inhalation.
Acute onset, transient (reversible) myocardial contraction abnormality has been described in patients with acute non-cardiac illness and after acute emotional stress. Such reversible myocardial contraction abnormalities may occur via mechanisms other than reduction in epicardial coronary blood flow. ⋯ The patient developed acute heart failure without evidence of carbon monoxide poisoning that resolved within 4 days. An association between brief smoke exposure without carbon monoxide poisoning and acute heart failure has not been previously described.

The mortality of patients with cardiogenic shock (CS) complicating ST elevation acute myocardial infarction (STEMI) remains high, despite early revascularization. Current knowledge of predictors of death is limited. ⋯ Hyperlactatemia, hyperglycemia and increased levels of uric acid on CCU admission are univariate predictors of in-hospital death. Moreover, at multivariate analysis, hyperlactatemia (>6.5 mmol/l) is an independent indicator of in-hospital death in CS patients complicating STEMI.

The purpose of this study was to assess the feasibility of measuring left atrial dysfunction with tissue Doppler imaging derived strain rate and to explore its role in predicting the maintenance of sinus rhythm after cardioversion for atrial fibrillation. ⋯ SR can be measured in the basal LA wall in atrial fibrillation and the magnitude of the early diastolic SR could predict the success of cardioversion and the likelihood of maintenance of sinus rhythm.
