Study summary

Little is known about the hyperemic efficacy of IV adenosine as well as safety in patients with heart failure with reduced ejection fraction (HFrEF) because they were excluded from the major FFR studies. We will evaluate the feasibility and hyperemic efficacy of IV adenosine in patients with HFrEF in comparison with IC nicorandil for invasive physiological assessment using a coronary pressure wire.

Read the detailed description

Little is known about the hyperemic efficacy of IV adenosine as well as safety in patients with heart failure with reduced ejection fraction (HFrEF) because they were excluded from the major FFR studies. We will evaluate the feasibility and hyperemic efficacy of IV adenosine in patients with HFrEF in comparison with IC nicorandil for invasive physiological assessment using a coronary pressure wire. Patients with an angiographically intermediate lesion (40-70% diameter stenosis) in a major epicardial coronary artery and with left ventricle ejection fraction ≤40% will be prospectively enrolled. FFR under the various hyperemic stimulation using IV adenosine 140 \& 180, IC adenosine, and IC nicorandil will be measured sequentially.

In context

Coronary Artery Disease

4,857 studies on the registry are indexed under Coronary Artery Disease; 890 are open to participants now.

This study's planned enrollment of 125 is close to the median of 124 across 3,006 interventional studies indexed under Coronary Artery Disease.

Inclusion criteria

  • angiographically proven epicardial intermediate stenosis (40-70%)
  • echocardiographically proven LV dysfunction ( ≤40%)

Exclusion criteria

Exclusion Criteria:

  • infarct-related artery, less than 2 weeks
  • Killip class 3 and 4
  • bronchial asthma
  • second degree or third degree AV block
  • any to adenosine
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Mar 2017 (actual). Primary completion is estimated for Feb 2020, 35 months after the start.

Of 753 non-industry interventional studies with no phase under Coronary Artery Disease, half reached primary completion within 33 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 53. This study's planned 35 months is close to that.

Counting every sponsor, half of 930 studies reached it within 30 months; a quarter within 15 and three quarters within 50.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 1, 2017, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
