MPMA Trial Summary

This trial will test whether drugs that improve blood flow, with or without supplements that may improve mitochondrial function, can improve exercise endurance and skeletal muscle function in people with HFpEF.

Who is the study for?
This trial is for adults with Heart Failure with Preserved Ejection Fraction (HFpEF), who have been on stable heart medication for at least a month. They should have certain signs of heart stress, like specific ratios in their echocardiogram or history of acute heart failure. Excluded are those under 18, pregnant women, people with severe other diseases or conditions that could interfere with the study, and those taking conflicting medications.Check my eligibility
What is being tested?
The study tests if Potassium Nitrate alone or combined with Propionyl-L-Carnitine and Nicotinamide Riboside can improve exercise endurance and muscle function in HFpEF patients. It compares these treatments to Potassium Chloride to see which is better at increasing blood flow and enhancing mitochondrial function.See study design
What are the potential side effects?
Possible side effects may include changes in blood pressure, dizziness upon standing due to orthostatic hypotension, potential impact on liver enzymes (ALT/AST levels), alterations in kidney function as measured by eGFR rates, and increased methemoglobin levels which affect oxygen delivery.

Frequently Asked Questions

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

Has the Food and Drug Administration granted authorization for Potassium Nitrate?

"Potassium Nitrate has been tested and garnered a score of 2 on the safety scale; while there is some data supporting its security, it has yet to be proven effective in clinical trials."

Answered by AI

What is the maximum number of participants included in this clinical investigation?

"Affirmative. The information hosted on clinicaltrials.gov reveals that this investigation is still actively recruiting, which began October 11th 2021 and was most recently modified April 27th 2022. At the moment, 53 participants are necessary for 1 centre involved in the trial."

Answered by AI

Does this trial restrict participants to those over 80 years of age?

"The age limits for this medical study are 18 and above, with an upper limit of 85 years old."

Answered by AI

Could I potentially be enrolled in this research program?

"A total of 53 individuals aged 18-85 suffering from heart failure with preserved ejection fraction (hfpef) may join this trial. Beyond that, they must have taken a stable medical therapy for at least one month and display NYHA Class II-III symptoms."

Answered by AI

In what medical contexts is Potassium Nitrate commonly administered?

"Potassium Nitrate is a helpful tool in managing congestive heart failure (CHF), increasing sensitivity, looking after teeth, and aiding with lower extremity issues."

Answered by AI

Could you provide information on preceding research involving Potassium Nitrate?

"Currently, 18 clinical research trials are underway on the efficacy of Potassium Nitrate. Of those active studies, 2 have advanced to Phase 3. Philadelphia serves as a major hub for these investigations with 22 locations conducting experiments into this medication's effects."

Answered by AI

Is enrollment still available for this experiment?

"Indeed, the data hosted on clinicaltrials.gov indicates that this medical study is actively recruiting patients. Initially posted on October 11th 2021, it has been recently updated as of April 27th 2022 and requires 53 participants from one site."
