High Blood Pressure clinical trials at UC Davis

This pilot randomized clinical trial compares dopamine and norepinephrine as first-line vasoactive therapies in term and late preterm neonates with pulmonary hypertension associated with hypoxemic respiratory failure and systemic hypotension. Systemic hypotension is a common and clinically significant complication of persistent pulmonary hypertension of the newborn (PPHN) and frequently requires vasopressor support to maintain adequate systemic perfusion. Dopamine is commonly used in this setting; however, prior animal experimental and clinical data suggest it may increase pulmonary vascular resistance, potentially worsening right ventricular afterload and hypoxemia. Norepinephrine may preferentially increase systemic vascular resistance with less effect on the pulmonary circulation. This study evaluates short-term hemodynamic and oxygenation responses following initiation of dopamine or norepinephrine.

The PHA Registry (PHAR) is a national study about people who have pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH). PHAR collects information from people with PAH and CTEPH who are cared for in participating PHA-accredited Pulmonary Hypertension Care Centers throughout the U.S. PHAR will determine how people with PAH and CTEPH are evaluated, tested, and treated, and will observe how well these participants do. The goal is to see if people with PH are treated according to recommended guidelines, and to see if there are certain factors that can lead to better or worse outcomes. PHAR will include information about people with PAH and CTEPH in the U.S. who are seen at participating PHA-accredited PH Care Centers. PHAR contains data about patient care and outcomes. Specifically, data in the PHAR includes information on diagnosis; clinical status; socioeconomic status; diagnosis test results; body size; treatment information; interest in participating in clinical trials; family health and social history; and information about smoking, alcohol, or drug use. Participants are followed over time, and provide updates such as changes in therapy, how often participants need to go to the hospital, and survival. Such information may help healthcare providers provide better care.
