About this study

HFpEF has a high incidence and lacks effective therapy, and its onset is closely related to systemic inflammation and intestinal dysbacteriosis.SGLT-2i exerts its effects by diuresis, anti-inflammatory and improving energy metabolism, whereas probiotics modulate intestinal flora, reduce inflammatory markers, and regulate immune responses.The combination of the two drugs is not only expected to exert synergistic therapeutic potential, but may also reduce the risk of sarcopenia associated with SGLT-2i weight loss.This study aims to combine henagliflozin and a probiotic preparation on the basis of standard anti-heart-failure therapy, and to observe their effects on cardiac and renal function, intestinal barrier function, quality of life, and exercise tolerance in elderly patients with HFpEF, while exploring the underlying mechanisms, so as to provide new data and therapeutic strategies for the treatment of elderly HFpEF patients.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Henggliflozin Combined with Probiotics and Henggliflozin in people with Heart Failure, Preserved Ejection Fraction, run by The First Affiliated Hospital of Air Force Medical University at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 7 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact JiChenyang (+86 15591423352, 3260126173@qq.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Kansas City Cardiomyopathy Questionnaire (KCCQ)scale score (time frame: Baseline, Week 4, Week 8,Week 12). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jul 2026.
