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.

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.

Coronavirus disease 2019 (COVID-19) represents a major health problem in terms of deaths and long-term sequelae. We conducted a retrospective cohort study at Montichiari Hospital (Brescia, Italy) to better understand the determinants of outcome in two different COVID-19 outbreaks. A total of 634 unvaccinated patients admitted from local emergency room to the Internal Medicine ward with a confirmed diagnosis of SARS-CoV-2 infection and a moderate-to-severe COVID-19 were included in the study. A group of 260 consecutive patients during SARS-CoV-2 first wave (from February to May 2020) and 374 consecutive patients during SARS-CoV-2 2nd/3rd wave (from October 2020 to May 2021) were considered. Demographic data were not significantly different between waves, except a lower prevalence of female sex during first wave. Mortality was significantly higher during the 1st wave than in the following periods (24.2% vs. 11%; p p p
