Mechanisms of Acute Decompensation of Heart Failure

In a recent study from our laboratory, Pr Paul Mulder and colleagues have developed a new animal model of acute cardiac decompensation induced by salt overload. Using this model, they investigated whether heart rate reduction (HRR) opposes the acute decompensation‐related aggravation of cardiovascular dysfunction. Briefly, they found that acute HRR, induced by the If current inhibitor S38844, opposes cardiac decompensation by preventing aggravation of cardiovascular dysfunction, including reduced myocardial tissue perfusion and coronary relaxation. Importantly, the protective effects of HRR persist beyond the transient treatment, and led to partial prevention of the development of pulmonary congestion. Whether early transient HRR induced by If current inhibitors or other bradycardic agents, i.e. beta‐blockers, exerts beneficial effects in human ADHF warrants further investigation.
