Abstract
INTRODUCTION
In patients with heart failure (HF) and reduced ejection fraction, increased heart rate (HR) is an independent risk factor for adverse outcomes. In systolic HF treatment with the If inhibitor ivabradine trial (SHIFT), Ivabradine improved survival when added to conventional treatment including β-blockers. However, the extent of benefit in the real world is unclear. We examined the characteristics of patients on guideline-directed therapy and determined who had SHIFT-like characteristics.

METHODS
A total of 1096 patients with chronic HF were reviewed from June 2014 to April 2015 in two HF clinics in Toronto: an academic institution (AI), and a community hospital (CH) clinic. SHIFT-like characteristics [left ventricular ejection fraction (LVEF) ≤35%; sinus rhythm; and HR ≥ 70 bpm] were described.

RESULTS
For all patients, mean age was 75 ± 13 years, overall LVEF was 44 ± 15%, AI less than CH (41.9 ± 14.0% vs. 45.7 ± 15.0%; p < 0.0001). More than two-thirds of patients in both groups were on β-blockers; with less than one-third at target dose. The proportion of patients with SHIFT-like characteristics was 8.4% AI and 11.7% CH, respectively (p = 0.0658). CONCLUSION
In HF clinics from both academic and community hospitals in Toronto, up-titration in the dose of β-blockers and other guideline therapy can be improved on. A small proportion of patients with HF and SHIFT-like characteristics may potentially benefit from the addition of Ivabradine, just approved in Canada; this number will be further reduced if target dosage for β-blockers is achieved.
