Take Your Blood Pressure to Heart

Help us find out if consuming more potassium will improve your heart health.

A research program of Tulane University Translational Science Institute and the National Institutes of Health

I am interested in participating

What is the PITCH study?

The PITCH Study aims to learn whether a higher intake of potassium lowers blood pressure, which may inform clinical and dietary guidelines for preventing hypertension (“high blood pressure”) among adults.

The goal is to establish safe, effective, and sustainable therapeutic options, like potassium supplementation, for treating hypertension and preventing heart disease.

This study is considered a “randomized controlled clinical trial.” If you qualify and are willing to participate in the study, we will assign you through a procedure like a coin toss to one group receiving oral potassium tablets or the other group receiving placebo tablets for 12 weeks. You will have an equal chance of being assigned to the treatment or placebo groups.

All participants will complete five clinic visits over the 12-week study. Free clinic parking is provided. Once enrolled in this study, you will receive gift cards for your time in participating.

Did you know

Nearly half of adults in the United States (47%, or 116 million) have hypertension, defined as a systolic blood pressure greater than 130 mm Hg or a diastolic blood pressure greater than 80 mm Hg, or are taking medication for hypertension. In 2020, more than 670,000 deaths in the United States had hypertension as a primary or contributing cause. Having high blood pressure puts you at risk for heart disease and stroke, which are the leading causes of death in the United States.

You may be eligible to join PITCH if…

  • You are 18 years of age or older
  • You have high blood pressure but are not currently taking medicine to lower your blood pressure

How might this study benefit you and society?

  • You will receive routine blood pressure measurements, height and weight, and lab tests during the trial at no cost to you. With your permission, you and your doctor will receive the results of these tests at the end of the study
  • Your participation may help people lower their blood pressure and improve heart health. 
  • This study may also contribute substantially to medical knowledge used to develop future treatment options
