Summary
In this research study, we are using heart imaging exams and blood testing, in order to gain an improved understanding of the pulmonary (lung) hypertension and cardiovascular (heart) complications that often occur in sickle cell patients. Information gathered from the healthy volunteers that participate in this study will be compared to information from the sickle cell patients in this study in order to help further our understanding.
Eligibility Criteria
Inclusion Criteria
- Patients must be 18+
- Patients who were diagnosed with SCD confirmed by high-pressure liquid chromatography or hemoglobin electrophoresis will be eligible for the study
- Only patients in stable condition will be included
- Patients receiving transfusions will not be excluded
Exclusion Criteria
- Patients with vaso-occlusive crises or an episode of acute chest syndrome within the previous four weeks (after 4 weeks have passed, the patients may be re-evaluated for eligibility)
- Patients with high degree heart block; active, hemodynamically significant, ventricular arrhythmias; unstable coronary syndromes; history of myocardial infarction within 1 month of the study.
- Contraindications to gadolinium-enhanced magnetic resonance examination such as severe claustrophobia, Pacemaker, defibrillators, cerebral aneurysm clips, or neurostimulator.
- Pregnancy
- Patients with sinus node dysfunction
