RESUMO
OBJECTIVE: To assess the value of opportunistic biomarkers derived from chest CT performed at hospital admission of COVID-19 patients for the phenotypization of high-risk patients. METHODS: In this multicentre retrospective study, 1845 consecutive COVID-19 patients with chest CT performed within 72 h from hospital admission were analysed. Clinical and outcome data were collected by each center 30 and 80 days after hospital admission. Patients with unknown outcomes were excluded. Chest CT was analysed in a single core lab and behind pneumonia CT scores were extracted opportunistic data about atherosclerotic profile (calcium score according to Agatston method), liver steatosis (≤ 40 HU), myosteatosis (paraspinal muscle F < 31.3 HU, M < 37.5 HU), and osteoporosis (D12 bone attenuation < 134 HU). Differences according to treatment and outcome were assessed with ANOVA. Prediction models were obtained using multivariate binary logistic regression and their AUCs were compared with the DeLong test. RESULTS: The final cohort included 1669 patients (age 67.5 [58.5-77.4] yo) mainly men 1105/1669, 66.2%) and with reduced oxygen saturation (92% [88-95%]). Pneumonia severity, high Agatston score, myosteatosis, liver steatosis, and osteoporosis derived from CT were more prevalent in patients with more aggressive treatment, access to ICU, and in-hospital death (always p < 0.05). A multivariable model including clinical and CT variables improved the capability to predict non-critical pneumonia compared to a model including only clinical variables (AUC 0.801 vs 0.789; p = 0.0198) to predict patient death (AUC 0.815 vs 0.800; p = 0.001). CONCLUSION: Opportunistic biomarkers derived from chest CT can improve the characterization of COVID-19 high-risk patients. CLINICAL RELEVANCE STATEMENT: In COVID-19 patients, opportunistic biomarkers of cardiometabolic risk extracted from chest CT improve patient risk stratification. KEY POINTS: ⢠In COVID-19 patients, several information about patient comorbidities can be quantitatively extracted from chest CT, resulting associated with the severity of oxygen treatment, access to ICU, and death. ⢠A prediction model based on multiparametric opportunistic biomarkers derived from chest CT resulted superior to a model including only clinical variables in a large cohort of 1669 patients suffering from SARS- CoV2 infection. ⢠Opportunistic biomarkers of cardiometabolic comorbidities derived from chest CT may improve COVID-19 patients' risk stratification also in absence of detailed clinical data and laboratory tests identifying subclinical and previously unknown conditions.

PURPOSE: To develop and validate an effective and user-friendly AI platform based on a few unbiased clinical variables integrated with advanced CT automatic analysis for COVID-19 patients' risk stratification. MATERIAL AND METHODS: In total, 1575 consecutive COVID-19 adults admitted to 16 hospitals during wave 1 (February 16-April 29, 2020), submitted to chest CT within 72 h from admission, were retrospectively enrolled. In total, 107 variables were initially collected; 64 extracted from CT. The outcome was survival. A rigorous AI model selection framework was adopted for models selection and automatic CT data extraction. Model performances were compared in terms of AUC. A web-mobile interface was developed using Microsoft PowerApps environment. The platform was externally validated on 213 COVID-19 adults prospectively enrolled during wave 2 (October 14-December 31, 2020). RESULTS: The final cohort included 1125 patients (292 non-survivors, 26%) and 24 variables. Logistic showed the best performance on the complete set of variables (AUC = 0.839 ± 0.009) as in models including a limited set of 13 and 5 variables (AUC = 0.840 ± 0.0093 and AUC = 0.834 ± 0.007). For non-inferior performance, the 5 variables model (age, sex, saturation, well-aerated lung parenchyma and cardiothoracic vascular calcium) was selected as the final model and the extraction of CT-derived parameters was fully automatized. The fully automatic model showed AUC = 0.842 (95% CI: 0.816-0.867) on wave 1 and was used to build a 0-100 scale risk score (AI-SCoRE). The predictive performance was confirmed on wave 2 (AUC 0.808; 95% CI: 0.7402-0.8766). CONCLUSIONS: AI-SCoRE is an effective and reliable platform for automatic risk stratification of COVID-19 patients based on a few unbiased clinical data and CT automatic analysis.

OBJECTIVES: We aimed to evaluate the use of bare metal stent (BMS) implantation in current percutaneous coronary intervention (PCI) era, focusing on indications for use and clinical outcomes. BACKGROUND: Limited data on BMS usage in current clinical practice are available. METHODS: All patients who underwent PCI with at least one BMS implantation in 18 Italian centers from January 1, 2013 to December 31, 2017, were included in our registry. Rates of BMS use and reasons for BMS implantations were reported for the overall study period and for each year. Primary outcomes were mortality, bleeding (Bleeding Academic Research Consortium-BARC and Thrombolysis in Myocardial Infarction-TIMI non-CABG definitions), and major adverse cardiac events (MACE) defined as the composite of all-cause and cardiac death, any myocardial infarction, target vessel revascularization, or any stent thrombosis. RESULTS: Among 58,879 patients undergoing PCI in the study period, 2,117 (3.6%) patients (mean age 73 years, 69.7% males, 73.3% acute coronary syndrome) were treated with BMS implantation (2,353 treated lesions). The rate of BMS implantation progressively decreased from 10.1% (2013) to 0.3% (2017). Main reasons for BMS implantation were: ST-elevation myocardial infarction (STEMI) (23.1%), advanced age (24.4%), and physician's perception of high-bleeding risk (34.0%). At a mean follow-up of 2.2 ± 1.5 years, all-cause and cardiac mortality were 25.6 and 12.7%, respectively; MACE rate was 35.3%, any bleeding rate was 13.0% (BARC 3-5 bleeding 6.3%, TIMI non-CABG major bleeding 6.1%). CONCLUSION: In a large, contemporary, real-world, multicenter registry, BMS use progressively reduced over the last 5 years. Main reasons for BMS implantation were STEMI, advanced age, and physician's perception of high-bleeding risk. High rates of mortality and MACE were observed in this real-world high-risk population.

OBJECTIVES: Enlarged main pulmonary artery diameter (MPAD) resulted to be associated with pulmonary hypertension and mortality in a non-COVID-19 setting. The aim was to investigate and validate the association between MPAD enlargement and overall survival in COVID-19 patients. METHODS: This is a cohort study on 1469 consecutive COVID-19 patients submitted to chest CT within 72 h from admission in seven tertiary level hospitals in Northern Italy, between March 1 and April 20, 2020. Derivation cohort (n = 761) included patients from the first three participating hospitals; validation cohort (n = 633) included patients from the remaining hospitals. CT images were centrally analyzed in a core-lab blinded to clinical data. The prognostic value of MPAD on overall survival was evaluated at adjusted and multivariable Cox's regression analysis on the derivation cohort. The final multivariable model was tested on the validation cohort. RESULTS: In the derivation cohort, the median age was 69 (IQR, 58-77) years and 537 (70.6%) were males. In the validation cohort, the median age was 69 (IQR, 59-77) years with 421 (66.5%) males. Enlarged MPAD (≥ 31 mm) was a predictor of mortality at adjusted (hazard ratio, HR [95%CI]: 1.741 [1.253-2.418], p < 0.001) and multivariable regression analysis (HR [95%CI]: 1.592 [1.154-2.196], p = 0.005), together with male gender, old age, high creatinine, low well-aerated lung volume, and high pneumonia extension (c-index [95%CI] = 0.826 [0.796-0.851]). Model discrimination was confirmed on the validation cohort (c-index [95%CI] = 0.789 [0.758-0.823]), also using CT measurements from a second reader (c-index [95%CI] = 0.790 [0.753;0.825]). CONCLUSION: Enlarged MPAD (≥ 31 mm) at admitting chest CT is an independent predictor of mortality in COVID-19. KEY POINTS: ⢠Enlargement of main pulmonary artery diameter at chest CT performed within 72 h from the admission was associated with a higher rate of in-hospital mortality in COVID-19 patients. ⢠Enlargement of main pulmonary artery diameter (≥ 31 mm) was an independent predictor of death in COVID-19 patients at adjusted and multivariable regression analysis. ⢠The combined evaluation of clinical findings, lung CT features, and main pulmonary artery diameter may be useful for risk stratification in COVID-19 patients.

AIMS: To evaluate the safety and the efficacy of fluoroscopy-guided only (Fluo-G) and of echocardiography-guided (Echo-G; trans-esophageal echocardiography-TEE-or intracardiac echocardiography-ICE) percutaneous closure of patent foramen ovale (PFO). METHODS AND RESULTS: Single center retrospective registry enrolling 368 consecutive patients (mean age 50.5 years) who underwent PFO closure between June 2004 and December 2011. Most patients had prior cryptogenic stroke (n = 126; 34.2%), TIA (n = 218; 51.1%); some of these had recurrent neurological events [multiple strokes n = 28 (7.8%); multiple TIAs n = 72 (18.6%)]. All the patients underwent a preprocedure TEE. PFO closure was performed with Echo-G in 187 patients (50.8%) (TEE n = 69, 36.8% and ICE n = 124, 66.3%). In Fluo-G cases, PFO with atrial septal aneurysm (ASA) was significantly less present (P < 0.005) and smaller devices (<25 mm) were implanted more frequently (P < 0.001). Both fluoroscopy and total procedural time were lower in the Fluo-G group (P < 0.0001). No differences were found in terms of successful device deployment (98.3% Fluo-G vs. 98.3% Echo-G) and RtL-shunt at follow-up (11.7% Fluo-G vs. 7.6% Echo-G). The rate of conversion from Fluoro-G to Echo-G procedure was 4.4% (n = 8). At a median follow-up of 4 years, freedom from recurrent embolic events rate was similar between the two groups (Echo-G 94.5 vs. Fluo-G 95.7%). CONCLUSIONS: In our experience Fluoro-G PFO closure was performed mainly in cases of simple anatomy, with similar results in terms of safety and efficacy compared to Echo-G cases. Both fluoroscopy and total procedural times were lower in the Fluo-G cases.

RATIONALE: At the onset of ST-elevation acute myocardial infarction (STEMI), patients can present with very high circulating interleukin-6 (IL-6(+)) levels or very low-IL-6(-) levels. OBJECTIVE: We compared these 2 groups of patients to understand whether it is possible to define specific STEMI phenotypes associated with outcome based on the cytokine response. METHODS AND RESULTS: We compared 109 patients with STEMI in the top IL-6 level (median, 15.6 pg/mL; IL-6(+) STEMI) with 96 in the bottom IL-6 level (median, 1.7 pg/mL; IL-6(-) STEMI) and 103 matched controls extracted from the multiethnic First Acute Myocardial Infarction study. We found minimal clinical differences between IL-6(+) STEMI and IL-6(-) STEMI. We assessed the inflammatory profiles of the 2 STEMI groups and the controls by measuring 18 cytokines in blood samples. We exploited clustering analysis algorithms to infer the functional modules of interacting cytokines. IL-6(+) STEMI patients were characterized by the activation of 2 modules of interacting signals comprising IL-10, IL-8, macrophage inflammatory protein-1α, and C-reactive protein, and monocyte chemoattractant protein-1, macrophage inflammatory protein-1ß, and monokine induced by interferon-γ. IL-10 was increased both in IL-6(+) STEMI and IL-6(-) STEMI patients compared with controls. IL-6(+)IL-10(+) STEMI patients had an increased risk of systolic dysfunction at discharge and an increased risk of death at 6 months in comparison with IL-6(-)IL-10(+) STEMI patients. We combined IL-10 and monokine induced by interferon-γ (derived from the 2 identified cytokine modules) with IL-6 in a formula yielding a risk index that outperformed any single cytokine in the prediction of systolic dysfunction and death. CONCLUSIONS: We have identified a characteristic circulating inflammatory cytokine pattern in STEMI patients, which is not related to the extent of myocardial damage. The simultaneous elevation of IL-6 and IL-10 levels distinguishes STEMI patients with worse clinical outcomes from other STEMI patients. These observations could have potential implications for risk-oriented patient stratification and immune-modulating therapies.

AIMS: Globally, nearly 20% of cardiovascular disease deaths were attributable to air pollution. Out-of-hospital cardiac arrest (OHCA) represents a major public health problem; therefore, the identification of novel OHCA triggers is of crucial relevance. The aim of the study was to evaluate the association between air pollution (short-, mid-, and long-term exposures) and OHCA risk, during a 7-year period in a highly polluted urban area in northern Italy, with a high density of automated external defibrillators (AEDs). METHODS AND RESULTS: Out-of-hospital cardiac arrests were prospectively collected from the 'Progetto Vita Database' between 1 January 2010 and 31 December 2017; day-by-day air pollution levels were extracted from the Environmental Protection Agency stations. Electrocardiograms of OHCA interventions were collected from the AED data cards. Day-by-day particulate matter (PM) 2.5 and 10, ozone (O3), carbon monoxide (CO), and nitrogen dioxide (NO2) levels were measured. A total of 880 OHCAs occurred in 748 days. A significant increase in OHCA risk with a progressive increase in PM2.5, PM10, CO, and NO2 levels was found. After adjustment for temperature and seasons, a 9% and 12% increase in OHCA risk for each 10 µg/m3 increase in PM10 (P < 0.0001) and PM2.5 (P < 0.0001) levels was found. Air pollutant levels were associated with both asystole and shockable rhythm risk, while no correlation was found with pulseless electrical activity. CONCLUSION: Short- and mid-term exposures to PM2.5 and PM10 are independently associated with the risk of OHCA due to asystole or shockable rhythm.

Kounis syndrome (KS) is a coronary syndrome in the setting of allergic/anaphylactic reactions and can be classified in three variants: vasospastic allergic angina (type I), allergic myocardial infarction (type II) and stent thrombosis (type III). The early diagnosis is of paramount importance for the correct management and the prognosis, being KS a life-threatening emergency condition. KS is not uncommon, but it is frequently unrecognized or undiagnosed in virtue of its broad clinical manifestations. The diagnosis should be based on the combination of cardiovascular and allergic/anaphylactic clinical symptoms and signs, as well as on laboratory, electrocardiographic, echocardiographic, and angiographic evidence. ECG monitoring, cardiac enzymes and troponin are mandatory to confirm or exclude KS in a patient with subclinical or clinical, acute or chronic allergic reactions. Nevertheless, the treatment is a real challenge for the emergency clinicians because guidelines have not been established yet, and the therapy is based on the variant type. We herein report the case of type I KS in a woman with no prior history of allergy, admitted to our emergency department for abdominal pain, nausea and hematochezia. Starting from this case we conducted a systematic search of the following databases: PubMed, Google Scholar, Science Direct, Medline, using the keywords of "Kounis syndrome", "coronary spams", "cardiac arrest", "sudden death", "allergy", and "anaphylaxis". The main purpose of this review is to remind emergency clinicians to keep a high index of suspicion regarding KS when dealing with patients with allergic reactions or anaphylaxis to promptly identify and correctly manage KS.

A 79-year-old woman was admitted to our coronary care unit for non-ST-elevation myocardial infarction. Urgent left transradial coronary angiography showed mid-distal high-grade stenosis of the left circumflex coronary artery. During percutaneous coronary intervention, stent dislodgement from the balloon catheter occurred. Fortunately, the guidewire was left in place through the detached stent, but a loop snare failed to cross the proximal circumflex artery. A second wire was placed in parallel to the first one and the first wire was caught in the loop snare, which was pulled back and closed at the level of the stent. Then, we cautiously pulled the guiding catheter together with the stent as a whole unit out of the introducer.

BACKGROUND: Elderly constitute a high-risk subset of patients but are under-represented in clinical revascularization trials. Our aim was to investigate clinical outcomes and prognosis predictors after percutaneous coronary intervention (PCI) in this population. METHODS: Unrestricted consecutive patients with ≥75 years who underwent PCI from 2012 to 2015 were enrolled. The primary ischemic endpoint was the composite of 1-year myocardial infarction, definite/probable stent thrombosis and target vessel revascularization. The primary bleeding endpoint was defined according to the Bleeding Academic Research Consortium (BARC) classification as BARC ≥ 2. RESULTS: We enrolled 708 patients (mean age 80 ± 4): 14% were very elderly patients (≥85 years), 27% of patients were diabetic, 23% had chronic kidney disease (CKD), 17% atrial fibrillation and 37% presented acute coronary syndrome. The primary ischemic endpoint was reported in 67 patients (12%): 29 had myocardial infarction (5%), 25 had definite/probable stent thrombosis (4.4%) and 44 had target vessel revascularization (8%). BARC ≥ 2 bleeding was reported in 43 patients (8%). No differences were found in terms of both ischemic and bleeding events between patients with <85 and ≥85 years. Three-vessel disease and use of bare metal stent were independent predictors of the primary ischemic endpoint. Triple antithrombotic therapy and CKD were the only independent predictors of BARC ≥ 2 bleedings. CONCLUSIONS: In our experience, elderly patients reported reassuring efficacy and safety outcomes after PCI, even if ischemic and bleeding events were frequent. Three-vessel disease and the use of bare metal stent were the only predictors of primary ischemic endpoint. Triple antithrombotic therapy and CKD were the only predictors of BARC ≥ 2 bleedings.

AIMS: Several studies have unveiled the great heterogeneity of COVID-19 pneumonia. Identification of the "vascular phenotype" (involving both pulmonary parenchyma and its circulation) has prognostic significance. Our aim was to explore the combined role of chest computed tomography (CT) scan and electrocardiogram (ECG) at hospital admission in predicting short-term prognosis and to draw pathophysiological insights. METHODS AND RESULTS: We analyzed the chest CT scan and ECG performed at admission in 151 consecutive COVID-19 patients admitted between 20 March and 4 April 2020. All-cause mortality within 30 days was the primary endpoint. Median age was 71 years (IQR: 62-76). Severe pneumonia was present in 25 (17%) patients, and 121 (80%) had abnormal ECG. During a median follow-up of 7 days (IQR: 4-13), 54 (36%) patients died. Deceased patients had more severe pneumonia than survivors did (80% vs. 64%, p = 0.044). ECG in deceased patients showed more frequently atrial fibrillation/flutter (17% vs. 6%, p = 0.039) and acute right ventricular (RV) strain (35% vs. 10%, p < 0.001), suggesting the "vascular phenotype". ECG signs of acute RV strain (HR 2.46, 95% CIs 1.36-4.45, p = 0.0028) were independently associated with all-cause mortality in multivariable analysis, and in the likelihood ratio test, showed incremental prognostic value over chest CT scan, age, and C-reactive protein. CONCLUSIONS: Combining chest CT scan and ECG data improves risk stratification in COVID-19 pneumonia by identifying a distinctive phenotype with both parenchymal and vascular damage of the lung. Patients with severe pneumonia at chest CT scan plus ECG signs of acute RV strain have an extremely poor short-term prognosis.
RESUMO
BACKGROUND: Kounis syndrome is a hypersensitivity coronary disorder induced by exposure to several triggers; the most common are antibiotics, followed by insect bites. METHODS: We reviewed the literature and identified 66 patients who experienced acute coronary syndrome after insect bites. RESULTS: The median age was 51 years, and 19.0% were women and only 12% had a history of allergy. The most involved insects were bee and wasp (86%) and the most frequent clinical manifestations were chest pain and anaphylaxis (36% and 29%, respectively). ST-segment elevation was the most common electrocardiographic finding (>70%). There was a not negligible rate of complications (15%), with a possible increased arrhythmic burden in patients without significant coronary atherosclerosis. CONCLUSIONS: Acute coronary syndrome after insect bites is not so rare and it could have serious complications, with a possible increased arrhythmic burden in patients without significant coronary atherosclerosis.

BACKGROUND: Patients with coronavirus disease 2019 (COVID-19) exhibit high thrombotic risk. The evidence on a potential independent prognostic role of antiplatelet treatment in those patients is limited. The aim of the study was to evaluate the prognostic impact of pre-admission low-dose acetylsalicylic acid (ASA) in a wide series of hospitalized patients with COVID-19. METHODS: This cohort study included 984 COVID-19 patients stratified according to ASA intake before hospitalization: ASA+ (n = 253) and ASA- (n = 731). Patients were included in ASA+ group if they received it daily in the 7 days before admission. 213 (83%) were on ASA 100 mg daily. Primary endpoint was a composite of in-hospital death and/or need for respiratory support upgrade, secondary endpoints were in-hospital death and need for respiratory support upgrade. RESULTS: Mean age was 72 [62; 81] with 69% of male patients. ASA+ patients were significantly older, with higher prevalence of comorbidities. No significant differences regarding the degree of respiratory dysfunction were observed. At 30-day Kaplan-Meier analysis, ASA+ patients had higher survival free from the primary endpoint and need for respiratory support upgrade, conversely in-hospital death did not significantly differ between groups. At multivariate analysis ASA intake was independently associated with a lower probability of reaching primary endpoint (HR 0.697, 95% C.I. 0.525-0.924; p = 0.012). CONCLUSIONS: In COVID-19 patients undergoing hospitalization, pre-admission treatment with ASA is associated with better in-hospital outcome, mainly driven by less respiratory support upgrade.

BACKGROUND AND AIMS: Several studies reported a high incidence of pulmonary embolism (PE) among patients with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection, but detailed data about clinical characteristics, risk factors of these patients and prognostic role of PE are still lacking. We aim to evaluate the occurrence of pulmonary embolism among patients with SARS-CoV-2 infection, and to describe their risk factors, clinical characteristics, and in-hospital clinical outcomes. METHODS: This is a multicenter Italian study including 333 consecutive SARS-CoV-2 patients admitted to seven hospitals from February 22 to May 15, 2020. All the patients underwent computed tomography pulmonary angiography (CTPA) for PE detection. In particular, CTPA was performed in case of inadequate response to high-flow oxygen therapy (Fi02≥0.4 to maintain Sp02≥92%), elevated D-dimer (>0.5µg/mL), or echocardiographic signs of right ventricular dysfunction. Clinical, laboratory and radiological data were also analyzed. RESULTS: Among 333 patients with laboratory confirmed SARS-CoV-2 pneumonia and undergoing CTPA, PE was detected in 109 (33%) cases. At CTPA, subsegmental, segmental, lobar and central thrombi were detected in 31 (29%), 50 (46%), 20 (18%) and 8 (7%) cases, respectively. In-hospital death occurred in 29 (27%) patients in the PE-group and in 47 (21%) patients in the non-PE group (p = 0.25). Patients in PE-group had a low rate of traditional risk factors and deep vein thrombosis was detected in 29% of patients undergoing compression ultrasonography. In 71% of cases with documented PE, the thrombotic lesions were located in the correspondence of parenchymal consolidation areas. CONCLUSIONS: Despite a low rate of risk factors for venous thromboembolism, PE is present in about 1 out 3 patients with SARS-CoV-2 pneumonia undergoing CTPA for inadequate response to oxygen therapy, elevated D-dimer level, or echocardiographic signs of right ventricular dysfunction. In most of the cases, the thromboses were located distally in the pulmonary tree and were mainly confined within pneumonia areas.

Recent clinical and demographical studies on COVID-19 patients have demonstrated that men experience worse outcomes than women. However, in most cases, the data were not stratified according to gender, limiting the understanding of the real impact of gender on outcomes. This study aimed to evaluate the disaggregated in-hospital outcomes and explore the possible interactions between gender and cardiovascular calcifications. Data was derived from the sCORE-COVID-19 registry, an Italian multicentre registry that enrolled COVID-19 patients who had undergone a chest computer tomography scan on admission. A total of 1683 hospitalized patients (mean age 67±14 years) were included. Men had a higher prevalence of cardiovascular comorbidities, a higher pneumonia extension, more coronary calcifications (63% vs.50.9%, p<0.001), and a higher coronary calcium score (391±847 vs. 171±479 mm3, p<0.001). Men experienced a significantly higher mortality rate (24.4% vs. 17%, p=0.001), but the death event tended to occur earlier in women (15±7 vs. 8±7 days, p= 0.07). Non-survivors had a higher coronary, thoracic aorta, and aortic valve calcium score. Female sex, a known independent predictor of a favorable outcome in SARS-CoV2 infection, was not protective in women with a coronary calcification volume greater than 100 mm3. There were significant differences in cardiovascular comorbidities and vascular calcifications between men and women with SARS-CoV2 pneumonia. The differences in outcomes can be at least partially explained by the different cardiovascular profiles. However, women with poor outcomes had the same coronary calcific burden as men. The presumed favorable female sex bias in COVID-19 must therefore be reviewed in the context of comorbidities, especially cardiovascular ones.

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.

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 â± â570.92 vs 206.80 â± â424.13 âmm2, p â< â0.001); Volume (487.79 â± â565.34 vs 207.77 â± â406.81, p â< â0.001)], aortic valve [Volume (322.45 â± â390.90 vs 98.27 â± â250.74 mm2, p â< â0.001; Agatston 337.38 â± â414.97 vs 111.70 â± â282.15, p â< â0.001)] and thoracic aorta [Volume (3786.71 â± â4225.57 vs 1487.63 â± â2973.19 mm2, p â< â0.001); Agatston (4688.82 â± â5363.72 vs 1834.90 â± â3761.25, p â< â0.001)] calcium values. Coronary artery calcium (HR 1.308; 95% CI, 1.046-1.637, p â= â0.019) and total thoracic calcium (HR 1.975; 95% CI, 1.200-3.251, p â= â0.007) 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.

Takotsubo syndrome (TTS) is one of the causes of myocardial infarction with non-obstructive coronary arteries, and is often triggered by physical events (e.g. acute respiratory failure), or emotional events (e.g. loss of a family member, cardiac stress induced by an acute illness). SARS-CoV-2 pneumonia currently represents a worldwide health problem; the correlations between cardiovascular disease, myocardial injury and SARS-CoV-2 infection are still unclear, but initial data show that myocardial damage represents a negative prognostic factor. Myocardial injury during SARS-CoV-2, as defined by a pathological rise in circulating troponin levels, is not an uncommon complication in hospitalized patients, and is significantly more frequent in intensive care unit patients and among those who died. In this setting, myocardial injury is mainly secondary to type 2 myocardial infarction (mismatch in myocardial oxygen supply and demand during respiratory failure); other causes include myocarditis, coronary thrombosis, sepsis or septic shock. At present, only few cases of TTS have been described during SARS-CoV-2. Here we report the case of a patient hospitalized for pneumonia and respiratory failure due to SARS-CoV-2 with subsequent onset of TTS triggered by both physical and emotional events.

Purpose There is still conflicting evidence to support postoperative rehabilitation protocols using immobilization following rotator cuff repair over early motion. The objective of the study was to evaluate the evolution of pain, shoulder function, and patients' perception of their health status up to 1 year after cuff rotator repair and a standard postoperative rehabilitation protocol consisting of 4 weeks of immobilization followed by a 2-week assisted controlled rehabilitation. Methods Descriptive, longitudinal, uncontrolled case-series study was performed on 49 patients who underwent arthroscopic rotator cuff repair following traumatic or degenerative lesions. VAS scale for pain, Constant-Murley score for function, and SF-12 score for quality of life were used as outcome measures and were administered before the rehabilitation treatment, at the end of the 2-week rehabilitation, 3 months, and 1 year after surgery. Results VAS pain score decreased significantly along the follow-up reaching almost a nil value after 1 year (0.2). Function as measured by Constant-Murley score had a significant improvement during follow-up, reaching a mean value of 84.6. The short form (SF)-12 score increased over time reaching 46.3 for the physical and 43.8 for the psychological dimension, respectively, at 1 year. Conclusion The present study confirmed an excellent outcome at 1 year after rotator cuff repair using a traditional 4-week immobilization followed by a 2-week rehabilitation protocol without evidence of tendon un-healing or re-tearing. Level of Evidence This is a level IV, therapeutic case series.
