COvid-19 LongitUdinal Multiethnic BioImaging Assessment of CARDiovascular Sequelae (COLUMBIA CARDS) Registry

COLUMBIA CARDS is a pilot study to understand how COVID-19 affects the heart. It is known that COVID-19 can affect the heart in different ways. COLUMBIA CARDS is studying why some COVID-19 survivors develop clinical conditions such as heart inflammation, fluid buildup, blood clots, and other cardiac problems during or after their COVID-19 illness, and why other ones do not. In this study, we will use cardiovascular magnetic resonance (CMR) and transthoracic echocardiography (TTE) to better understand the impact of COVID-19 on the heart.

This is a pilot study aiming to collect preliminary data on cardiac imaging (CMR and TTE) in outpatients who recovered from COVID-19.

CMR offers the unique ability to comprehensively characterize myocardial tissue and assess the heart's structure and function, through a variety of complementary imaging techniques using different pulse sequences. The investigators propose to provide a multi-sequence CMR evaluation of a spectrum of convalescent COVID-19 patients, compare COVID-19 survivors to controls, and study the relationships between myocardial characteristics by CMR and echocardiography and health outcomes, and how these are modulated through patient characteristics, and clinical characteristics of COVID-19 illness. Broadly, this myocardial characterization will not just provide diagnosis but serve as a potentially powerful tool for risk stratification, therapeutic decision making, and monitoring response to therapies in COVID-19 survivors.

Transthoracic echocardiography (TTE) is the most widely used imaging technique for the assessment of cardiac morphology and function. While its capability for myocardial tissue characterization is inferior to that of CMR, TTE provides several advantages that make it an ideal complement to CMR for the assessment of cardiac involvement in COVID-19 patients. TTE offers a rapid noninvasive evaluation of myocardial and valvular function, in addition to the assessment of other cardiac abnormalities of interest (such as presence and amount of pericardial effusion) and important hemodynamic variables (noninvasive estimation of pulmonary pressures is an example). TTE is easily performed and reproducible, and does not involve the use of radiations or contrast agents, which allows the performance of repeat evaluations to assess serial changes over time in the cardiac parameters of interest.
