      Inotropic support in ischemic acute heart failure (AHF) is controversial. We tested a therapeutic principle for AHF by combining a low dose of omecamtiv mecarbil (OM; 0.25 mg/kg bolus plus 0.25 mg/kg/h) with a low dose of dobutamine (Dobut; 1.25 µg/kg/min). In 10 pigs subjected to myocardial ischemia by left coronary microembolization, this cotreatment increased cardiac power (CP) from 0.48 ± 0.14 ...
    • Opposite diastolic effects of omecamtiv mecarbil versus dobutamine and ivabradine co-treatment in pigs with acute ischemic heart failure 

      Rønning, Leif; Bakkehaug, Jens P.; Rødland, Lars; Kildal, Anders B.; Myrmel, Truls; How, Ole-Jakob (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-10-11)
      Acute ischemic cardiogenic shock is associated with poor prognosis, and the impact of inotropic support on diastolic function in this context is unclear. We assessed two suggested new inotropic strategies in a clinically relevant pig model of ischemic acute heart failure (AHF): treatment with the myosin activator omecamtiv mecarbil (OM) or dobutamine and ivabradine (D+I). Left ventricular (LV) ...
