Clinical Trial Summary
Post COVID-19 pulmonary hypertension can develop as a result of lung parenchymal damage and
altered pulmonary circulation induced by COVID-19 infection. It has been proposed that this
type of PH should be considered a combination between PH of group 3 (due to interstitial
fibrosis and alveolar inflammation) and 4 (induced by thrombotic/thromboembolic processes,
endothelial injury, or, at least, hypoxic vasoconstriction). Right heart catheterization
(RHC) is the gold standard for assessing pulmonary hemodynamics and is mandatory for
confirming the diagnosis of pulmonary hypertension (PH), assessing the severity of
hemodynamic impairment, and performing vasoreactivity testing in selected patients
Description:
Coronavirus disease 2019 (COVID-19), the highly contagious viral illness caused by severe
acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has had a catastrophic effect on the
world's demographics resulting in more than 3.8 million deaths worldwide, emerging as the
most consequential global health crisis since the era of the influenza pandemic of 1918.
COVID-19 survivors may experience persistent symptoms affecting different organ systems after
the acute phase of infection. Early reports suggest residual effects of SARS-CoV-2 infection,
involving respiratory, cardiovascular, musculoskeletal, integumentary, gastrointestinal,
endocrine, and neurological systems. Post-acute COVID-19 could be defined as persistent
symptoms and/or delayed or long-term complications of SARS-CoV-2 infection beyond 4 weeks
from the onset of symptoms. It is further divided into two categories: (1) subacute or
ongoing symptomatic COVID-19, which includes symptoms and abnormalities present from 4-12
weeks beyond acute COVID-19; and (2) chronic or post-COVID- 19 syndrome, which includes
symptoms and abnormalities persisting or present beyond 12 weeks of the onset of acute
COVID-19 and not attributable to alternative diagnoses. Pulmonary hypertension (PH) is a
clinical disorder involving multiple pathophysiological processes that ultimately affect the
vasculature within the lungs.
According to the 6th World Symposium on Pulmonary Hypertension, pulmonary hypertension (PH)
is defined by mean pulmonary arterial pressure (mPAP) >20 mmHg. "Pre-capillary PH" is
considered if additionally pulmonary arterial wedge pressure (PAWP) is ≤15 mmHg and pulmonary
vascular resistance (PVR) is ≥3 Wood units (WU). "Post-capillary PH" is defined as mPAP >20
mmHg with PAWP >15 mmHg. In the case of PVR <3 WU, we talk about "isolated post-capillary
PH", while in the case of PVR ≥3 WU the criteria for "combined pre- and post-capillary PH"
are fulfilled. Post COVID-19 pulmonary hypertension can develop as a result of lung
parenchymal damage and altered pulmonary circulation induced by COVID-19 infection. It has
been proposed that this type of PH should be considered a combination between PH of group 3
(due to interstitial fibrosis and alveolar inflammation) and 4 (induced by
thrombotic/thromboembolic processes, endothelial injury, or, at least, hypoxic
vasoconstriction). Right heart catheterization (RHC) is the gold standard for assessing
pulmonary hemodynamics and is mandatory for confirming the diagnosis of pulmonary
hypertension (PH), assessing the severity of hemodynamic impairment, and performing
vasoreactivity testing in selected patients.
Hypothesis and assumptions:
We hypothesize that pulmonary hypertension explain some of residual symptoms in COVID-19
survivors.
Aim of work:
The aim of this study is to assess pulmonary hemodynamics in COVID-19 survivors.
