The effect of this pure heart rate-lowering effect on cardiac function has been assessed in an echocardiographic sub-study. A post-hoc analysis from SHIFT assessed the impact of ivabradine on early readmissions in patients hospitalized for heart failure.
Swedberg K et al. Reverting the force—frequency relationship by ivabradine might be beneficial in this unstable situation, particularly when heart rate is markedly elevated and this hypothesis needs to be tested. Important clinical questions remain regarding early initiation and potential extension of indications which need to be addressed in future clinical trials.

Despite their beneficial effects, beta blockers have some untoward effects which become more pronounced in patients with HFrEF, including hypotension and decreased inotropy. Heart failure due to systolic dysfunction and mortality in diabetes: There was no evidence of a differential safety profile of ivabradine according to SBP.
This mirrored heart rate reduction, which occurred early on: A study comparing early to late administration of ivabradine is therefore needed to see whether this results in an optimization of titration and in potential clinical benefit. The purpose of this review is i to summarize the key findings of the SHIFT trial and ii to discuss its implications for daily practice.
Prognostic and symptomatic benefits with ivabradine: No episode of third-degree AV block was observed. Multiple comorbidities are frequent in patients with HF and are the rule in elderly patients over 65 years. In HFpEF, prolonging diastole in an abnormally stiff left ventricle might result in an improved LV filling with potential clinical benefit.
Rehospitalizations for heart failure. Efficacy and safety of ivabradine in patients with chronic systolic heart failure and diabetes: Chronic heart failureIvabradinePharmacological treatmentClinical trials. The conclusion of this analysis is that ivabradine can be used safely and is efficient in patients with CHF and diabetes.
This reduction was also observed on LV end-diastolic index and there was a 2. This beneficial effect was observed in a well-treated population: Ivabradine in the management of coronary artery disease with or without left ventricular dysfunction or heart failure.
This page was last modified on 3 Decemberat Chronic exposure to ivabradine reduces readmissions in the vulnerable phase after hospitalization for worsening systolic heart failure: The benefit was also similar in patients with or without an ischaemic aetiology of HF.
Ivabradine and outcomes in chronic heart failure (SHIFT): a randomised placebo-controlled study.
Ivabradine significantly reduced the risk of early recurrent hospitalizations following a first heart failure hospitalization. This sub-study shows that ivabradine is similarly effective and safe in CHF patients with or without chronic obstructive pulmonary disease and can be safely combined with beta-blockers in this high-risk population.
Mechanism of action of ivabradine in heart failure. The novel sinus node modifying agent ivabradine lowers heart rate by inhibiting the “funny current” I f channel which is critical in determining the automaticity rate of pacemaking cells in the sinoatrial node. Renal impairment, worsening renal function and outcome in patients with heart failure: One potential explanation for the beneficial effect ivabradinf heart rate reduction on cardiac dimensions is the reduction of afterload.
The only mechanism of action of ivabradine is to reduce heart rate when elevated through blockade of the If channel in the sinoatrial node. Following the main publication of the trial, a number of sub-studies have been conducted in order to address key issues such as role on quality of live, mechanism of action and, most importantly, efficacy and safety in patients with comorbidities which can affect management of heart failure HF and make it more complex.
Multimorbidity was associated with a higher risk of outcomes but, whatever the number of comorbidities, did not interfere with the effects of ivabradine in reducing the primary end point of cardiovascular death or hospitalization for heart failure or in reducing other heart failure-related outcomes.
This mechanism is supported by studies demonstrating strong associations between increasing resting heart rate HR and cardiovascular outcomes in patients with ischemic cardiomyopathy. This includes patients with chronic obstructive pulmonary disease, renal dysfunction, diabetes, and patients with low SBP. Ivabradine, a funny current If inhibitor, has been developed for symptomatic therapy of angina and in chronic heart failure CHF with low ejection fraction.
Finally, ivabradine reduced substantially the risk of ivabravine readmission for HF within 30 days 4. A major mechanism by which these agents are thought to provide benefit is by reducing myocardial oxygen demand by lowering heart rate through antagonism of sympathetic receptors in myocardial pacemaking tissue.
Rehospitalization is associated with a substantially increased risk of subsequent death and the risk is more important in the early phase after hospitalization. Effects of selective heart rate reduction with ivabrarine on left ventricular remodeling and function: Heart failure is a disabling condition associated with a poor quality of life. The beneficial effect on the outcomes detailed above occurred rapidly, and the survival curves show that the separation was rapid after randomization.
The presence of comorbidities makes management of HF more complex due to an increase in the risk of poor tolerability of HF medications or of contra-indications.
Clinical profiles and outcomes in patients with chronic heart failure and chronic obstructive pulmonary disease:
