Abstract

Background

Heart rate (HR) is of relevant prognostic value not only in the general population and patients with cardiovascular disease, but also in critically ill patients with multiple organ dysfunction syndrome (MODS). An elevated HR in MODS patients is associated with a worse prognosis. Beta-blocker (BB) administration has been shown to reduce mortality in MODS. In most cases, negative inotropic effects prevent administration of BBs in MODS patients. In this trial we investigate, whether the “funny current” (If) channel inhibitor ivabradine is able and apt to reduce pathologically elevated HR in MODS patients. We hypothesize that critically ill patients could derive particular benefit from the specific HR-lowering agent ivabradine.

Methods

MODIfY is a prospective, single centre, open label, randomized, controlled two arms, phase II-trial to evaluate the potential of ivabradine to reduce an elevated HR in MODS patients. The primary end point is the proportion of patients with a reduction of HR by at least 10 beats per minute (bpm) within 4 days. This trial will randomize 70 patients (men and women, aged ≥18 years) with newly diagnosed MODS, with an elevated HR (sinus rhythm with HR ≥90 bpm) and contraindications to BB therapy. Treatment period will last for 4 days. All patients will be followed for 6 months.

Results

The first patient was randomized on May 21, 2010.

Conclusions

The MODIfY trial is the first application of ivabradine as a pure heart rate reducing agent in MODS patients.
