Quantification of myocardial extracellular volume without blood sampling.

Aims: Cardiac magnetic resonance (CMR) 1 relaxation time mapping is an established technique primarily used to identify diffuse interstitial fibrosis and oedema. The myocardial extracellular volume (ECV) can be calculated from pre- and post-contrast 1 relaxation times and is a reproducible parametric index of the proportion of volume occupied by non-cardiomyocyte components in myocardial tissue. The conventional calculation of the ECV requires blood sampling to measure the haematocrit (HCT).

Article Synopsis
- A study was conducted to compare cardiac issues in patients after recovering from COVID-19 and after receiving COVID-19 vaccinations, focusing on findings from cardiac magnetic resonance (CMR) examinations.
- Out of 104 patients examined post-COVID-19, about 32.7% were diagnosed with conditions like isolated pericarditis and myocarditis, many of whom had severe COVID-19 cases requiring hospitalization or oxygen support.
- In a separate examination of 27 patients after vaccination, 81.5% were diagnosed with various cardiac issues, notably a higher incidence of myocarditis among vaccinated individuals compared to those recovering from COVID-19.
Background: Case series have reported persistent cardiopulmonary symptoms, often termed long-COVID or post-COVID syndrome, in more than half of patients recovering from Coronavirus Disease 19 (COVID-19). Recently, alterations in microvascular perfusion have been proposed as a possible pathomechanism in long-COVID syndrome. We examined whether microvascular perfusion, measured by quantitative stress perfusion cardiac magnetic resonance (CMR), is impaired in patients with persistent cardiac symptoms post-COVID-19.
