Study Summary

This trial is to study the effects of inorganic nitrate on blood pressure, blood nitrate levels, breath nitric oxide levels, and exercise performance, in order to see if it is an effective therapy for heart failure.

Who is the study for?
This trial is for adults aged 18-75 with heart failure characterized by reduced ejection fraction (NYHA II-IV) and stable on certain heart medications. Excluded are pregnant individuals, those with severe liver disease, recent other nitrate treatments, complex heart issues, or conditions affecting exercise test performance.Check my eligibility
What is being tested?
The study tests if potassium nitrate pills can improve blood pressure, blood nitrate levels, breath NO levels, and exercise performance in heart failure patients. It compares the effects of these pills to beetroot juice shots and looks at different doses.See study design
What are the potential side effects?
While not explicitly listed in the provided information, common side effects of nitrates like potassium nitrate may include headaches, dizziness, flushing or a drop in blood pressure.

Trial Design

2Treatment groups
Experimental Treatment
Group I: 20mmol KNO3Experimental Treatment1 Intervention
Intervention: Subjects with heart failure will receive a single oral dose of potassium nitrate (10 or 20 mmol KNO3) in 2 gelatin capsules during dose visit 1 and the other dose (10 or 20 mmol KNO3) during dose visit 2. The dose order will be randomized.
Group II: 10mmol KNO3Experimental Treatment1 Intervention
Intervention: Subjects with heart failure will receive a single oral dose of potassium nitrate (10 or 20 mmol KNO3) in 2 gelatin capsules during dose visit 1 and the other dose (10 or 20 mmol KNO3) during dose visit 2. The dose order will be randomized.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Has any prior research been conducted regarding KNO3, potassium nitrate?

"Currently, 4 clinical trials dedicated to the investigation of potassium nitrate (KNO3) are being conducted. Of these studies, 1 is in Phase 3 and the other three span over four separate locations located in Santiago, Región Metropolitana."

Answered by AI

Is the age threshold for participation in this trial set above 55 years old?

"This research endeavour is seeking participants aged 18 and above, yet not exceeding 74 years of age."

Answered by AI

What criteria is necessary for a person to qualify for enrollment in this trial?

"This research project aims to recruit 20 individuals between 18 and 74, all of whom are suffering from heart failure. The necessary requirements for eligibility include stable medical therapy over the preceding 30 days - with no major addition or removal (or change greater than 100%) of beta-adrenergic blockers, ACE inhibitors or angiotensin receptor blockers - as well as an age within the range mentioned previously."

Answered by AI

What is the capacity for enrollment in this clinical trial?

"This clinical trial is no longer recruiting participants; it was initially posted in October 2017 and last updated on February 2022. Alternatively, those looking for medical studies may be interested to know that 700 heart failure trials are currently being conducted and 4 KNO3 (potassium nitrate) research initiatives are actively enrolling patients."

Answered by AI

Are there any spots available for participation in this experiment?

"Unfortunately, the trial posted on clinicaltrials.gov is no longer actively recruiting patients after its last update in February of 2022. Nonetheless, there are 704 other medical studies seeking participants at this time."
