Brief 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

Detailed 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.
