Study Summary

This trial looks at how heart flow differs in SCD patients vs healthy people under stress to see if decreased blood flow is causing heart damage in SCD patients.

Who is the study for?
This trial is for adults aged 18-21 with Sickle Cell Disease (SCD) and heart dysfunction, specifically those with abnormal diastolic parameters. It includes three groups: SCD patients with diastolic dysfunction, those without it, and healthy black individuals as controls.Check my eligibility
What is being tested?
The study aims to measure blood flow reserve in the heart using PET scans during rest and stress conditions. Researchers will compare results between SCD patients with varying levels of heart function and healthy people to understand the cause of heart damage in SCD.See study design
What are the potential side effects?
[13N]NH3 and Lexiscan used in PET imaging may cause brief discomfort or reactions like headache, dizziness, nausea, or flushing. The risk is generally low but varies by individual.

Frequently Asked Questions

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

Has the FDA cleared Stratum C for medical use?

"While there is some evidence that Stratum C is safe, it is only from a Phase 2 trial, so it received a score of 2."

Answered by AI

Are research facilities still signing up participants for this experiment?

"This particular clinical trial, as indicated on clinicaltrials.gov, is not taking on new patients at the moment. However, it is worth noting that the trial's last update was on October 13th, 2022 and that there are 200 other trials with open enrollment currently."

Answered by AI

Might I be a candidate to sign up for this research project?

"The trial is looking for 40 participants, aged 18 to 21, who have anemia or sickle cell. Patients must also meet the following criteria: Inclusion Criteria - Stratum A: Sickle cell patients with diastolic dysfunction, 18 to 21 years of age, Diagnosis of SCD of HbSS and HbSβ0thalassemia genotypes, Three or more abnormal diastolic parameters (based on guidelines by American Society of echocardiography), Black, Inclusion Criteria - Stratum B: Sickle cell patients without diastolic dysfunction, Two or less abnormal di"
