Peripheral blood and blood following a pulmonary wedge pressure will be obtained from
patients undergoing right heart catheterizations.
patients undergoing right heart catheterizations.
It is well known that left sided heart disease can lead to pulmonary hypertension via a
number of proposed mechanisms. The purpose in this study is to identify biomarkers in
pulmonary hypertension to further understand the pathophysiology of this disease in patients
with heart disease.Patients are recruited in the cardiac catheterization lab, which are
undergoing right heart catheterization as per their plan of care established by their primary
cardiologist. During the procedure, we will ask the performing cardiologist to obtain a blood
sample of 40-50 milliliters from the catheter that they are using during the procedure. These
blood samples will be sent for analysis of biomarkers. The patient will then have an
echocardiogram done 1 year from their heart catheterization.
