Dual MRI for Cardiopulmonary COVID-19 Long Haulers
Characterizing the Long-Term Cardiopulmonary Effects of COVID-19 With Hyperpolarized Xenon and Cardiac MRI
Study Overview
Detailed Description
The proposed research builds on the established sensitivity of Hyperpolarized 129Xe MRI to obstructive and pulmonary vascular lung disease, features expected to represented in the Covid-19 cohort. It further incorporates a new understanding of the possible role of myocardial injury in these recovered patients by combining cutting-edge pulmonary and cardiac MRI.
Although the initial presentation of patients with moderate to severe symptoms of COVID19 infections is dominated by respiratory symptoms, 10% go on to develop persistent post-infection symptoms which are thought to have an inflammatory etiology. Evidence suggests that pathologic activation of the inflammasome persists beyond the acute initial presentation that contributes to the persistent disabling symptoms characterized as "long-haul COVID". For this trial, subjects will be eligible for enrollment if subjects are outpatients with a history of a laboratory-confirmed diagnosis of COVID-19 infection, and after 60 days or longer. The study team will accrual 13 subjects who continue to have respiratory symptoms (i.e., cough, shortness of breath, dyspnea on exertion). An additional 10 subjects engaged in competitive sports and diagnosed with COVID-19 will also be enrolled. These subjects can be asymptomatic or mildly to moderately. Although rare, cardiac impairment has been documented in <2% of these individuals. The study team knowledge, XeMRI has not yet been studied in this specific patient subset.
Existing data highlight significant racial and ethnic disparities with historically underserved minority populations (i.e., Black, LatinX) suffering disproportionately higher infection rates and more severe illness compared to Whites. This is reflected by the population enrolled in the study team RedCAP database and biorepository. As such 30% of subjects enrolled will be required to be from underserved communities.
