Implementation of sodium-glucose co-transporter 2 inhibitors in heart failure through a digital strategy
What happened
Digital outreach increases 6-month SGLT2 inhibitor initiation by ~127% vs usual care.
- P<0.001
- 18.6% vs 8.2% at 6 months
Does this change practice?
Where experts agree
Both clinicians who commented substantively agree that the main story is an implementation win: digital outreach can meaningfully close the treatment gap for proven heart failure therapy, even if clinical outcomes did not separate.
What this trial adds
Experts view EMAIL-HF as an implementation success that doubled SGLT2 inhibitor starts through digital outreach, though they note it did not translate into clinical outcome benefits in this timeframe.
Published field read
Clinicians and commentators frame EMAIL-HF as a proof of concept for closing the gap between guideline-recommended therapy and real-world prescribing. The reaction is broadly positive about the digital strategy's ability to boost treatment uptake, but everyone acknowledges the trial showed no outcome signal. The open question is whether longer follow-up or broader adoption would eventually convert higher prescribing into fewer hospitalizations and deaths.
Still open
Questions raised in published commentaryWhether the higher rate of SGLT2 inhibitor initiation will eventually translate into reduced hospitalizations or death with longer follow-up remains unanswered.
It is also unclear how scalable the digital strategy is across different health systems and patient populations.

Why the trial?
SGLT2 inhibitors improve heart failure outcomes yet remain underprescribed in routine care. EMAIL-HF tested whether a direct-to-patient digital outreach strategy can close this implementation gap and increase initiation of guideline-recommended therapy.

Key Points
- To test the effectiveness of a digital outreach strategy (EMAIL-HF) in initiating guideline-directed SGLT2 inhibitor therapy among patients with heart failure.
- Evaluated the EMAIL-HF digital outreach strategy compared to usual care in patients diagnosed with heart failure.
- Assessed prescription initiation rates of SGLT2 inhibitor therapy and a secondary composite clinical endpoint at 6 months of follow-up.
- SGLT2 inhibitor initiation at 6 months was 18.6% with the digital strategy versus 8.2% with usual care (p<0.001).
- The secondary composite endpoint of heart-failure hospitalisation or death occurred in 13.0% in the digital strategy arm versus 14.0% with usual care (p=0.276).

Limitations & tradeoffs
Statistical certainty
sample size, denominators and design details are not reported.
Design limitations
record is derived from the ESC press release with no simultaneous results paper, and clinical-outcome follow-up is limited to 6 months, too short to expect an initiation gain to translate into events.

Highlights that the digital strategy more than doubled SGLT2 inhibitor initiation at 6 months (18.6% vs 8.2%) in 5,996 patients with HF. Frames the result as showing digital pathways can move care from evidence to implementation.

Implication
Digital outreach boosts SGLT2 inhibitor initiation in heart failure; extends implementation evidence for scalable GDMT interventions.
Abstract
EMAIL-HF tested a digital outreach strategy to start proven SGLT2 inhibitor therapy in patients with heart failure. At 6 months, SGLT2 inhibitor initiation was 18.6% with the digital strategy versus 8.2% with usual care (p<0.001). The secondary composite of heart-failure hospitalisation or death was 13.0% versus 14.0% (p=0.276). No simultaneous results paper was available at presentation; source is the ESC Congress 2026 press release, 29 August 2026.

Mariam Elmegaard (2026) conducted an RCT in heart failure. digital outreach strategy vs. usual care was evaluated on SGLT2 inhibitor initiation (p=<0.001). A digital outreach strategy significantly increased SGLT2 inhibitor initiation at 6 months compared to usual care (18.6% vs 8.2%, p<0.001).
