“…Our study is consistent with six studies that have reported lower peak VO2 among those with PASC compared to recovered individuals at 3-6 months after COVID-19. [19][20][21][22][23][24] Our findings build upon earlier studies by (1) demonstrating reduced peak VO2 and chronotropic incompetence much later after infection than other published studies, (2) also including evaluation of cardiac inflammation, structural heart disease and cardiovascular arrhythmias, (3) adjusting for likely confounders in our models, (4) including recovered persons as comparators, and (5) and demonstrating associations with higher inflammatory markers early in PASC. These studies, together with studies that included SARS-CoV-2 uninfected controls and casestudies without controls, have not reached consistent conclusions regarding patterns of reduced exercise capacity.…”

“…Two studies attributed lower peak Durstenfeld et al CPET, CMR, and Ambulatory Rhythm Findings >12 months after COVID-19 VO2 to inadequate augmentation of stroke volume 30 or chronotropic incompetence and poor stroke volume augmentation. 21 Others have attributed exercise limitations to ventilatory inefficiency from pulmonary vasculopathy, 18 respiratory abnormalities, 19 obesity and differences in cardiorespiratory fitness 29 and deconditioning. 20,21 Impaired oxygen extraction at the peripheral level (assessed using invasive CPET) has also been suggested to explain reduced exercise capacity among those with PASC at 11 months after infection by Singh et al 31 However, they describe stopping CPETs once RER was greater than 1.10 or heart rate was >85% predicted, which is below maximal exercise for most individuals and does not allow evaluation of chronotropic incompetence.…”

“…[13][14][15][16][17] Studies using cardiopulmonary exercise testing (CPET) have consistently demonstrated reduced exercise capacity at 3-6 months after SARS-CoV-2 infection with mixed results regarding classification of the etiology of exercise limitation. [17][18][19][20][21] Finally, to our knowledge, whether arrhythmias explain palpitations in PASC is unknown beyond 3 months. 22,23 The Long-Term Impact of Infection with Novel Coronavirus (LIINC) study (NCT 04362150) was implemented to study COVID-19 recovery in individuals with confirmed SARS-COV-2 and includes individuals with asymptomatic to severe acute disease.…”

BACKGROUNDMechanisms underlying persistent cardiopulmonary symptoms following SARS-CoV-2 infection (post-acute sequelae of COVID-19 “PASC” or “Long COVID”) remain unclear. The purpose of this study was to elucidate the pathophysiology of cardiopulmonary PASC using multimodality cardiovascular imaging including cardiopulmonary exercise testing (CPET), cardiac magnetic resonance imaging (CMR) and ambulatory rhythm monitoring.METHODSIn the Long-Term Impact of Infection with Novel Coronavirus (LIINC) Cohort, we performed CMR, CPET, and ambulatory rhythm monitoring among adults > 1 year after PCR-confirmed SARS-CoV-2 infection. We used logistic and linear regression to compare those with and without cardiopulmonary symptoms (dyspnea, chest pain, palpitations) adjusting for confounders.RESULTSOne hundred twenty individuals were studied, among whom 46 participants (unselected for symptom status) had at least one advanced test performed at median 17 months (IQR 15-18). Median age was 52 (IQR 42-61), 18 (39%) were female, and 6 (13%) were hospitalized for severe acute infection. On CMR (n=39), smaller RV volume and stroke volume and higher extracellular volume were present among those with symptoms, but no evidence of late-gadolinium enhancement or differences in T1 or T2 mapping were demonstrated. We did not find arrhythmias on ambulatory monitoring. In contrast, on CPET (n=39), 13/15 (87%) participants with reduced exercise capacity (<85% predicted) reported cardiopulmonary symptoms or fatigue (p=0.008). Adjusted peak VO2 was 2.7 ml/kg/min lower among those with cardiopulmonary symptoms (95%CI −6.9 to 1.5; p=0.20) or −11% predicted (95%CI −27 to 5, p=0.17). Including fatigue along with cardiopulmonary symptoms, the adjusted difference in peak VO2 was −5.9 ml/kg/min (−9.6 to −2.3; p=0.002) or −21% predicted (−35 to −7; p=0.006). Chronotropic incompetence was the primary abnormality among 9/15 with reduced peak VO2. Adjusted heart rate reserve <80% was associated with reduced exercise capacity (OR 15.6, 95%CI 1.30-187; p=0.03). Those with chronotropic incompetence had higher hsCRP, lower heart rate recovery, and lower heart rate variability suggestive of autonomic dysfunction.CONCLUSIONSReduced exercise capacity and reduced heart rate response to exercise, and hsCRP are associated with persistent cardiopulmonary symptoms more than 1 year following COVID-19. Chronic inflammation and autonomic dysfunction may underlie cardiopulmonary PASC.Clinical PerspectiveWhat is New?Impaired chronotropic response to exercise is associated with reduced exercise capacity and cardiopulmonary symptoms more than 1 year after SARS-CoV-2 infection.Findings on ambulatory rhythm monitoring point to perturbed autonomic function, while cardiac MRIfindings argue against myocardial dysfunction and myocarditis.Clinical ImplicationsCardiopulmonary testing to identify etiologies of persistent symptoms in post-acute sequalae of COVID-19 or “Long COVID” should be performed in a manner that allows for assessment of heart rate response to exercise.Therapeutic trials of antiviral, anti-inflammatory, and exercise strategies in PASC are urgently needed and should include assessment of symptoms and objective testing with cardiopulmonary exercise testing.

Los efectos a largo plazo de la enfermedad respiratoria por el virus SARS-CoV-2 en la población adulta es una situación que genera preocupación, porque altera aspectos físicos y mentales del paciente al punto de propiciar una incapacidad en sus funciones cotidianas. Por lo tanto, esta investigación tiene el propósito de comprender las implicaciones del síndrome post COVID-19 en la salud mental en la etapa adulta de la vida. Para la estructuración de la metodología se utiliza la declaración PRISMA 2020 la cual proporciona una síntesis clara de la información del tema en estudio. Entre las conclusiones encontramos que la afectación a largo plazo tiene consecuencias a nivel psicológico y psiquiátrico manifestado en dificultades emocionales en todas las actividades diarias, expresadas en tristezas, bajo nivel de ánimo y percepción de los logros, desmejora la calidad de vida, afecta el estado funcional, la cognición y llega a producir discapacidad importante.

ImportanceReduced exercise capacity is commonly reported among individuals with COVID-19 symptoms more than 3 months after SARS-CoV-2 infection (long COVID-19 [LC]). Cardiopulmonary exercise testing (CPET) is the criterion standard to measure exercise capacity and identify patterns of exertional intolerance.ObjectivesTo estimate the difference in exercise capacity among individuals with and without LC symptoms and characterize physiological patterns of limitations to elucidate possible mechanisms of LC.Data SourcesA search of PubMed, EMBASE, Web of Science, preprint servers, conference abstracts, and cited references was performed on December 20, 2021, and again on May 24, 2022. A preprint search of medrxiv.org, biorxiv.org, and researchsquare.com was performed on June 9, 2022.Study SelectionStudies of adults with SARS-CoV-2 infection more than 3 months earlier that included CPET-measured peak oxygen consumption (V̇o2) were screened independently by 2 blinded reviewers; 72 (2%) were selected for full-text review, and 35 (1%) met the inclusion criteria. An additional 3 studies were identified from preprint servers.Data Extraction and SynthesisData extraction was performed by 2 independent reviewers according to the PRISMA reporting guideline. Data were pooled using random-effects models.Main Outcomes and MeasuresDifference in peak V̇o2 (in mL/kg/min) among individuals with and without persistent COVID-19 symptoms more than 3 months after SARS-CoV-2 infection.ResultsA total of 38 studies were identified that performed CPET on 2160 individuals 3 to 18 months after SARS-CoV-2 infection, including 1228 with symptoms consistent with LC. Most studies were case series of individuals with LC or cross-sectional assessments within posthospitalization cohorts. Based on a meta-analysis of 9 studies including 464 individuals with LC symptoms and 359 without symptoms, the mean peak V̇o2 was −4.9 (95% CI, −6.4 to −3.4) mL/kg/min among those with symptoms with a low degree of certainty. Deconditioning and peripheral limitations (abnormal oxygen extraction) were common, but dysfunctional breathing and chronotropic incompetence were also described. The existing literature was limited by small sample sizes, selection bias, confounding, and varying symptom definitions and CPET interpretations, resulting in high risk of bias and heterogeneity.Conclusions and RelevanceThe findings of this systematic review and meta-analysis study suggest that exercise capacity was reduced more than 3 months after SARS-CoV-2 infection among individuals with symptoms consistent with LC compared with individuals without LC symptoms, with low confidence. Potential mechanisms for exertional intolerance other than deconditioning include altered autonomic function (eg, chronotropic incompetence, dysfunctional breathing), endothelial dysfunction, and muscular or mitochondrial pathology.
