Hemodynamics, baroreflex index and blood biomarkers of a patient who died after being affected by COVID-19: case report

SARS-CoV-2 Aiming for the Heart: A Multicenter Italian Perspective About Cardiovascular Issues in COVID-19

“…For instance, it has been suggested that the state of "silent hypoxemia" (i.e., depressed dyspnea response) that was observed in a large number of COVID-19 patients could be associated with defects in the carotid body, which is known to express ACE2 (Tobin et al, 2020). The consequent poor regulation of blood displacement in the microcirculation to the lungs and the brain may therefore mirror a vitiated baroreceptor reflex and hemodynamics, as was indeed observed in a COVID-19 patient (Ribas et al, 2020). Importantly, countless cardiovascular implications have been associated with the frequent renal involvement that was observed in level 2 and level 3 patients (Ronco et al, 2020).…”

Association between functional neurometry test results and blood biomarkers indicative of anaemia, subclinical inflammation, and endothelial dysfunction

“…The Functional Neurometry of the author Nelson Alves Pereira Júnior is a methodology that enables an intercommunication between Biofeedback resources already studied and scientifically demonstrated, such as: sensor that captures heart rate variability (HRV), galvanic skin response, cardiac coherence (synchrony between the frequencies of the respiratory cycle, heart rate and blood pressure), peripheral temperature sensors, respiratory rate and heart rate meter. 1 The author organized his Functional Neurometry method in an assessment established in 3 (three) positions (dorsal position; standing up and standing) and named the categories of this initial investigative protocol: Anxiety control; baroreflex index; Hemodynamic; Physiological response and brain neurometry. 2 In the first category, entitled anxiety control, the non-cognitive response (not voluntarily controlled in a rational way) is measured, that is, the ANS response.…”

“…2 Another relevant category of this initial psychophysiological assessment concerns the functioning of baroceptors. 5 The more the baroceptors are activated, the more functional oxygen is transported to the mitochondria, 1 especially in the places where the mitochondria are more agglomerated, which are: brain, muscles and ganglia. 6 However, it is important to clarify that functional oxygen is not oxygen saturation.…”

“…2 This functioning with active and constant movement of these mechanoreceptors also seems to indicate that there is a good flow in the blood displacement also called hemodynamic at the level of blood microcirculation. 1 In the process of investigating the functioning of oxygen transport, the category entitled physiological response stands out, which also attests to the functionality of the sympathetic and parasympathetic systems made possible through the thermoregulation sensor located in the annular proximal phalanx. 10 During the care of several volunteer patients at a clinic of the Instituto do Cérebro de Pernambuco (ICerPE), in the city of Recife/ PE, a possible association was observed between the findings of the results of the Functional Neurometry tests, anaemia, subclinical inflammation and/ or endothelial dysfunction.…”
