Background: Coronavirus disease 2019 (COVID-19) has spread worldwide determining dramatic impacts on healthcare systems. Early identification of high-risk parameters is required in order to provide the best therapeutic approach. Coronary, thoracic aorta and aortic valve calcium can be measured from a non-gated chest computer tomography (CT) and are validated predictors of cardiovascular events and all-cause mortality. However, their prognostic role in acute systemic inflammatory diseases, such as COVID-19, has not been investigated., Objectives: The aim was to evaluate the association of coronary artery calcium and total thoracic calcium on in-hospital mortality in COVID-19 patients., Methods: 1093 consecutive patients from 16 Italian hospitals with a positive swab for COVID-19 and an admission chest CT for pneumonia severity assessment were included. At CT, coronary, aortic valve and thoracic aorta calcium were qualitatively and quantitatively evaluated separately and combined together (total thoracic calcium) by a central Core-lab blinded to patients' outcomes., Results: Non-survivors compared to survivors had higher coronary artery [Agatston (467.76 ​± ​570.92 vs 206.80 ​± ​424.13 ​mm 2 , p ​< ​0.001); Volume (487.79 ​± ​565.34 vs 207.77 ​± ​406.81, p ​< ​0.001)], aortic valve [Volume (322.45 ​± ​390.90 vs 98.27 ​± ​250.74 mm 2 , p ​< ​0.001; Agatston 337.38 ​± ​414.97 vs 111.70 ​± ​282.15, p ​< ​0.001)] and thoracic aorta [Volume (3786.71 ​± ​4225.57 vs 1487.63 ​± ​2973.19 mm 2 , p ​< ​0.001); Agatston (4688.82 ​± ​5363.72 vs 1834.90 ​± ​3761.25, p ​< ​0.001)] calcium values. Coronary artery calcium (HR 1.308; 95% CI, 1.046-1.637, p ​= ​0.019) and total thoracic calcium (HR 1.975; 95% CI, 1.200-3.251, p ​= ​0.007) resulted to be independent predictors of in-hospital mortality., Conclusion: Coronary, aortic valve and thoracic aortic calcium assessment on admission non-gated CT permits to stratify the COVID-19 patients in-hospital mortality risk., (Copyright © 2021 Society of Cardiovascular Computed Tomography.

Background and Aims: Ideal Cardiovascular Health (ICH), defined as optimal levels of cardiovascular (CV) health factors and behaviors, has been reported to be very low in adults and children, with consequent several negative health outcomes and higher CV risk. The present study investigated the burden of ICH among Italian adolescents and its association with carotid-femoral pulse wave velocity (cf-PWV)., Methods and Results: 387 healthy adolescents (mean age 17.1 ± 1.4 years) attending the "G. Donatelli" High School in Terni, Italy, were evaluated. ICH was assessed through clinical evaluation, laboratory measures and interviewer-administered questionnaires. Cf-PWV was measured by arterial tonometry (SphygmoCor). For each ICH metric, a score of 2 was assigned for ideal levels, 1 for intermediate, and 0 for poor. All subjects showed at least one ICH metric, whereas none showed all ICH 7 metrics. The average number of ICH metrics was 4.3 ± 1.1. The highest rates were observed for fasting blood glucose (98%), whereas an ideal healthy diet was achieved only by 8% of subjects. The Cf-PWV was inversely and linearly associated with the sum of ICH metrics (p = 0.03) and the ICH score (p < 0.01). At the multivariate analysis, the association between ICH score and cf-PWV remained significant after adjustment for age, sex, heart rate, mean arterial pressure and other confounders (p = 0.04)., Conclusion: ICH is relatively uncommon among Italian adolescents and inversely related to cf-PWV. Our results showed a detrimental association between CV unhealthy factors and behaviors with increased aortic stiffness, which starts developing at an early stage of the lifespan., Competing Interests: Declaration of competing interest None., (Copyright © 2021 The Italian Diabetes Society, the Italian Society for the Study of Atherosclerosis, the Italian Society of Human Nutrition and the Department of Clinical Medicine and Surgery, Federico II University.

Background and Aims: The potential impact of coronary atherosclerosis, as detected by coronary artery calcium, on clinical outcomes in COVID-19 patients remains unsettled. We aimed to evaluate the prognostic impact of clinical and subclinical coronary artery disease (CAD), as assessed by coronary artery calcium score (CAC), in a large, unselected population of hospitalized COVID-19 patients undergoing non-gated chest computed tomography (CT) for clinical practice., Methods: SARS-CoV 2 positive patients from the multicenter (16 Italian hospitals), retrospective observational SCORE COVID-19 (calcium score for COVID-19 Risk Evaluation) registry were stratified in three groups: (a) "clinical CAD" (prior revascularization history), (b) "subclinical CAD" (CAC >0), (c) "No CAD" (CAC = 0). Primary endpoint was in-hospital mortality and the secondary endpoint was a composite of myocardial infarction and cerebrovascular accident (MI/CVA)., Results: Amongst 1625 patients (male 67.2%, median age 69 [interquartile range 58-77] years), 31%, 57.8% and 11.1% had no, subclinical and clinical CAD, respectively. Increasing rates of in-hospital mortality (11.3% vs. 27.3% vs. 39.8%, p < 0.001) and MI/CVA events (2.3% vs. 3.8% vs. 11.9%, p < 0.001) were observed for patients with no CAD vs. subclinical CAD vs clinical CAD, respectively. The association with in-hospital mortality was independent of in-study outcome predictors (age, peripheral artery disease, active cancer, hemoglobin, C-reactive protein, LDH, aerated lung volume): subclinical CAD vs. No CAD: adjusted hazard ratio (adj-HR) 2.86 (95% confidence interval [CI] 1.14-7.17, p=0.025); clinical CAD vs. No CAD: adj-HR 3.74 (95% CI 1.21-11.60, p=0.022). Among patients with subclinical CAD, increasing CAC burden was associated with higher rates of in-hospital mortality (20.5% vs. 27.9% vs. 38.7% for patients with CAC score thresholds≤100, 101-400 and > 400, respectively, p < 0.001). The adj-HR per 50 points increase in CAC score 1.007 (95%CI 1.001-1.013, p=0.016). Cardiovascular risk factors were not independent predictors of in-hospital mortality when CAD presence and extent were taken into account., Conclusions: The presence and extent of CAD are associated with in-hospital mortality and MI/CVA among hospitalized patients with COVID-19 disease and they appear to be a better prognostic gauge as compared to a clinical cardiovascular risk assessment., (Copyright © 2021 Elsevier B.V.
