Introduction The Coronavirus disease 2019 (COVID-19), doesn't affect only respiratory system, but it also involves other organs including cardiovascular system, possibly causing acute or chronic cardiovascular events. Preexisting cardiovascular diseases enhance COVID-19 morbidity, as well. Aim In this retrospective analysis we investigated the onset of cardiovascular events during a time-span of more than one year since hospitalization (384 days). Methods The analysis included 43 patients, who were hospitalized in Internal Medicine Department of Montichiari Hospital (ASST Spedali Civili of Brescia) for moderate to severe SARS-CoV2 related pneumonia treated with high-flow oxygen support (ranging from 40% fraction of inspired oxygen to non-invasive ventilation) Mean age was 63 years, 28% (12/43) were female and 72% (31/43) were male. Thirty-five percent of the patients suffered from heart diseases, 56% of them were hypertensives and 23% had type 2 diabetes; 12% had chronic kidney disease (CKD) and 5% an active neoplasm. 49% of the sample was obese. Nineteen percent took ACE inhibitors and 19% was on ARBs. Statins were taken by 37% of the patients; an antiaggregant by 21%, and an anticoagulant by 2% (see table) Results The follow-up visit included the evaluation of post-covid infection quality-of-life, standard laboratory tests, chest computed tomography, spirometry with evaluation of DLCO. The onset of cardiovascular events during the average period of 384 days was evaluated. None of the 43 patients had major cardiovascular events: coronary heart disease, cerebrovascular disease, peripheral arterial disease, deep vein thrombosis and pulmonary embolism. Conclusions Even if this study failed to demonstrate new-onset CV events, longer follow-up studies performed to evaluate cardiovascular risk following SARS-CoV1 infection showed persistent hyperlipidemia, cardiovascular system abnormalities, and glucose metabolism disorders in a very high number of patients. Further analyses are needed to further investigate longer term cardiovascular consequences of SARS-CoV2 infection.
Aim there is evidence of significant clinical sequelae of COVID-19 that may impair both life length and its quality. Aim of this study was to assess the long-term consequences of moderate to severe SARS-CoV-2-related pneumonia in patients requiring high-flow oxygen treatment. Methods This prospective follow-up study included 45 patients with confirmed COVID-19 admitted to a medical ward at the Montichiari Hospital, Brescia, Italy from November 2020 to April 2021 Patients had COVID-19 related pneumonia with respiratory failure and needed at least treatment with an inspired fraction of oxygen of 40% (of them, 59% were treated with Venturi mask and 41% needed non-invasive ventilation). Patients underwent a clinical assessment with standard laboratory testing, chest CT scan, lung function tests with DLCO, and evaluation of vital parameters after a mean of 382 days after hospital discharge. A quality-of-life questionnaire was administered to each willing patient. Results See table for details. While standard laboratory testing showed a substantial normalization, we found persistence of radiological alterations (i.e. ground-glass opacities, irregular linear/reticular opacities) in 61% of patients; mean Tiffenau index (FEV1/FVC) was reduced, although not clearly pathologic (79%) and 38% of patients showed a mild to moderate reduction in CO lung diffusion (DLCO). Interestingly, 54% of subjects showed concomitant presence of radiologic alterations AND persistence of dyspnea OR reduction in CO lung diffusion, while 21% had all three concomitant conditions, compatible with the diagnosis of lung fibrosis. Overall, a total of 75% patients had some degree of functional or structural alteration of respiratory apparatus. We also evaluated quality of life thorough a structured questionnaire: after more than one year 62% of the patients still lamented fatigue, 62% effort dyspnea, 12% anorexia, 29% dysgeusia or anosmia, 31% insomnia and 43% anxiety. Conclusions these data seem to demonstrate that SARS-CoV-2-related pneumonia requiring high flow oxygen has a heavy long-term burden, both in terms of persistence of functional and structural pulmonary damage (which may be progressive and evolve to a more severe degree) and of burden on overall quality daily life.
Introduction COVID-19 pandemic still represents a major clinical problem worldwide. Many studies are actively being carried out to better understand prognostic factors of outcome as well as optimal treatment. Aim ACE-2 receptor is highly expressed on the surface of cardiac and pulmonary cells, and it is used by coronaviruses to enter host cells; this makes the role of ACE-inhibitors and Angiotensin Receptor Blockers (ARBs) drugs controversial. Moreover, it is still unclear whether these drugs may have any impact on sequelae. Methods In this retrospective study, we analysed a group of 244 hypertensive unvaccinated patients (134 on ACE-inhibitors, 110 on ARBs) admitted for moderate to severe COVID-19 pneumonia. As shown in the table, the two groups where homogeneous. Of these patients, 46 (20 treated with ACE-I and 26 treated with ARBs) came to a follow-up visit after a mean of 260 days; they underwent a quality-of-life assessment, laboratory and radiologic tests and spirometry (with DLCO). Results A total of 20 of 110 (18%) patients under treatment with ARBs and 23 of 134 (17%) died during hospitalization (p=0.8, NS). At discharge, biochemical, radiological and respiratory data were not significantly different. We did not find any significant difference in terms of radiologic alterations, lung fibrosis, spirometry data, DLCO, persisting effort dyspnea. Biochemical data were substantially super-imposable in the two groups. Conclusions we could not detect any difference in outcome nor in complications type or number in the two groups undergoing treatment with ACE-inhibitor or ARBs. This result seems to support and to strengthen the idea that ACE-inhibitors and ARBs do not play a significant role in onset, evolution and outcome of moderate to severe COVID-19 pneumoniae. Although the number of follow-up patients is small, we did not find any difference in follow-up sequelae in both groups.
