Impact of vaccination on electrocardiograms of hospitalized patients for Covid-19.

Introduction: We sought to assess the impact of SarsCov-2 vaccination on admission12-lead electrocardiogram of hospitalized patients. Methods: We retrospectively analyzed and compared admission 12-lead electrocardiograms of all patients hospitalized in dedicated Internal Medicine Unit for Covid-19 both in pre-vaccination period (PV) and after vaccination (V). Results: 667 consecutive Covid-19 in-patients were enrolled in the study: PV hospitalized patients were older (68vs57 years, p < 0.01), had higher rates of atrial fibrillation/flutter (13%vs2.5%, p < 0.01), any arrhythmia (26%vs8%, p < 0.01), and ST-T abnormalities (22%vs7.4%, p < 0.01). Mortality rates in hospitalized Covid-19 patients were higher before vaccination period (20%vs4%, p < 0.01). Minimal vaccination coverage of population (V period) was inversely and independently associated with in-hospital mortality (odds ratio 0.09, 95%CI 0.01-0.68, p < 0.05). Conclusions: SarsCov-2 vaccination campaign and even partial coverage of local population was associated with less frequent abnormalities at admission ECG in hospitalized non-critically hill Covid-19 patients and lower mortality.

The Evolving Phenotypes of Cardiovascular Disease during COVID-19 Pandemic.

COVID-19 pandemic has negatively impacted the management of patients with acute and chronic cardiovascular disease: acute coronary syndrome patients were often not timely reperfused, heart failure patients not adequately followed up and titrated, atrial arrhythmias not efficaciously treated and became chronic. New phenotypes of cardiovascular patients were more and more frequent during COVID-19 pandemic and are expected to be even more frequent in the next future in the new world shaped by the pandemic. We therefore aimed to briefly summarize the main changes in the phenotype of cardiovascular patients in the COVID-19 era, focusing on new clinical challenges and possible therapeutic options.

Electrocardiographic Pathological Findings Caused by the SARS-CoV-2 Virus Infection: Evidence from a Retrospective Multicenter International Cohort Longitudinal Pilot Study of 548 Subjects.

COVID-19 has threatened the capability of receiving and allocating patients in emergency departments (EDs) all over the world. This is a retrospective cohort study to explore the role of a simple procedure like an ECG to screen for the severity of COVID-19 on admission to the ED. For this study, 548 consecutive patients were enrolled in a multicenter international registry and stratified upon ECG on admission with a simple distinction between normal vs. abnormal rhythm. Among patients in the abnormal ECG group were those with heart rates higher than 100 beats per minute and/or atrial fibrillation. Survival in patients with normal ECG rhythm was deemed below 75% after 58 days and then stabilized, while survival in patients with abnormal ECG rhythm was deemed below 75% after 11 days and below 50% after 21 days. A multivariate analysis including abnormal rhythm, gender, age, diabetes, obesity, respiratory failure during hospitalization, heart failure during hospitalization, and abnormal rhythm was an independent predictor of death (HR 7.20 95% CI 3.63-14.28, p < 0.01). This finding, if confirmed in large prospective studies, is promising for identifying a cheap and simple procedure for patients in need of a closer look.

Aspirin Therapy on Prophylactic Anticoagulation for Patients Hospitalized With COVID-19: A Propensity Score-Matched Cohort Analysis of the HOPE-COVID-19 Registry.

Background COVID-19 is an infectious illness, featured by an increased risk of thromboembolism. However, no standard antithrombotic therapy is currently recommended for patients hospitalized with COVID-19. The aim of this study was to evaluate safety and efficacy of additional therapy with aspirin over prophylactic anticoagulation (PAC) in patients hospitalized with COVID-19 and its impact on survival. Methods and Results A total of 8168 patients hospitalized for COVID-19 were enrolled in a multicenter-international prospective registry (HOPE COVID-19). Clinical data and in-hospital complications, including mortality, were recorded. Study population included patients treated with PAC or with PAC and aspirin. A comparison of clinical outcomes between patients treated with PAC versus PAC and aspirin was performed using an adjusted analysis with propensity score matching. Of 7824 patients with complete data, 360 (4.6%) received PAC and aspirin and 2949 (37.6%) PAC. Propensity-score matching yielded 298 patients from each group. In the propensity score-matched population, cumulative incidence of in-hospital mortality was lower in patients treated with PAC and aspirin versus PAC (15% versus 21%, Log Rank P=0.01). At multivariable analysis in propensity matched population of patients with COVID-19, including age, sex, hypertension, diabetes, kidney failure, and invasive ventilation, aspirin treatment was associated with lower risk of in-hospital mortality (hazard ratio [HR], 0.62; [95% CI 0.42-0.92], P=0.018). Conclusions Combination PAC and aspirin was associated with lower mortality risk among patients hospitalized with COVID-19 in a propensity score matched population compared to PAC alone.

Fever following Covid-19 vaccination in subjects with Brugada syndrome: Incidence and management.

BACKGROUND: Fever is a potential side effect of the Covid-19 vaccination. Patients with Brugada syndrome (BrS) have an increased risk of life-threatening arrhythmias when experiencing fever. Prompt treatment with antipyretic drugs is suggested in these patients. AIM OF THE STUDY: To evaluate the incidence and management of fever within 48 h from Covid-19 vaccination among BrS patients. METHODS: One hundred sixty-three consecutive patients were enrolled in a prospective registry involving five European hospitals with a dedicated inherited disease ambulatory. RESULTS: The mean age was 50 ± 14 years and 121 (75%) patients were male. Prevalence of Brugada electrocardiogram (ECG) pattern type-1, -2, and -3 was 32%, 44%, and 24%, respectively. Twenty-eight (17%) patients had an implantable cardioverter-defibrillator (ICD). Fever occurred in 32 (19%) BrS patients after 16 ± 10 h from vaccination, with a peak of body temperature of 37.9° ± 0.5°. Patients with fever were younger (39 ± 13 vs. 48 ± 13 years, p = .04). No additional differences in terms of sex and cardiovascular risk factors were found between patients with fever and not. Twenty-seven (84%) out of 32 patients experienced mild fever and five (16%) moderate fever. Pharmacological treatment with antipyretic drugs was required in 18 (56%) out of 32 patients and was associated with the resolution of symptoms. No patient required hospital admission and no arrhythmic episode was recorded in patients with ICD within 48 h after vaccination. No induced type 1 BrS ECG pattern and new ECG features were found among patients with moderate fever. CONCLUSION: Fever is a common side effect in BrS patients after the Covid-19 vaccination. Careful evaluation of body temperature and prompt treatment with antipyretic drugs may be needed.

Gender Differences in Takotsubo Syndrome.

BACKGROUND: Male sex in takotsubo syndrome (TTS) has a low incidence and it is still not well characterized. OBJECTIVES: The aim of the present study is to describe TTS sex differences. METHODS: TTS patients enrolled in the international multicenter GEIST (GErman Italian Spanish Takotsubo) registry were analyzed. Comparisons between sexes were performed within the overall cohort and using an adjusted analysis with 1:1 propensity score matching for age, comorbidities, and kind of trigger. RESULTS: In total, 286 (11%) of 2,492 TTS patients were men. Male patients were younger (age 69 ± 13 years vs 71 ± 11 years; P = 0.005), with higher prevalence of comorbid conditions (diabetes mellitus 25% vs 19%; P = 0.01; pulmonary diseases 21% vs 15%; P = 0.006; malignancies 25% vs 13%; P < 0.001) and physical trigger (55 vs 32% P < 0.01). Propensity-score matching yielded 207 patients from each group. After 1:1 propensity matching, male patients had higher rates of cardiogenic shock and in-hospital mortality (16% vs 6% and 8% vs 3%, respectively; both P < 0.05). Long-term mortality rate was 4.3% per patient-year (men 10%, women 3.8%). Survival analysis showed higher mortality rate in men during the acute phase in both cohorts (overall: P < 0.001; matched: P = 0.001); mortality rate after 60 days was higher in men in the overall (P = 0.002) but not in the matched cohort (P = 0.541). Within the overall population, male sex remained independently associated with both in-hospital (OR: 2.26; 95% CI: 1.16-4.40) and long-term mortality (HR: 1.83; 95% CI: 1.32-2.52). CONCLUSIONS: Male TTS is featured by a distinct high-risk phenotype requiring close in-hospital monitoring and long-term follow-up.

The paradox of pulmonary arterial hypertension in Italy in the COVID-19 era: is risk of disease progression around the corner?

OBJECTIVE: The coronavirus disease 2019 (COVID-19) outbreak has led to significant restrictions on routine medical care. We conducted a multicentre nationwide survey of patients with pulmonary arterial hypertension (PAH) to determine the consequences of governance measures on PAH management and risk of poor outcome in patients with COVID-19. MATERIALS AND METHODS: The present study, which included 25 Italian centres, considered demographic data, the number of in-person visits, 6-min walk and echocardiographic test results, brain natriuretic peptide/N-terminal pro-brain natriuretic peptide test results, World Health Organization functional class assessment, presence of elective and non-elective hospitalisation, need for treatment escalation/initiation, newly diagnosed PAH, incidence of COVID-19 and mortality rates. Data were collected, double-checked and tracked by institutional records between March 1 and May 1, 2020, to coincide with the first peak of COVID-19 and compared with the same time period in 2019. RESULTS: Among 1922 PAH patients, the incidences of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and COVID-19 were 1.0% and 0.46%, respectively, with the latter comparable to that in the overall Italian population (0.34%) but associated with 100% mortality. Less systematic activities were converted into more effective remote interfacing between clinicians and PAH patients, resulting in lower rates of hospitalisation (1.2% versus 1.9%) and related death (0.3% versus 0.5%) compared with 2019 (p<0.001). A high level of attention is needed to avoid the potential risk of disease progression related to less aggressive escalation of treatment and the reduction in new PAH diagnoses compared with 2019. CONCLUSION: A cohesive partnership between healthcare providers and regional public health officials is needed to prioritise PAH patients for remote monitoring by dedicated tools.

Electrocardiographic findings and mortality in covid-19 patients hospitalized in different clinical settings.

BACKGROUND: Twelve-lead electrocardiogram (ECG) represents the first-line approach for cardiovascular assessment in patients with Covid-19. OBJECTIVES: We sought to describe and compare admission ECG findings in 3 different hospital settings: intensive-care unit (ICU) (invasive ventilatory support), respiratory care unit (RCU) (non-invasive ventilatory support) and Covid-19 dedicated internal-medicine unit (IMU) (oxygen supplement with or without high flow). We also aimed to assess the prognostic impact of admission ECG variables in Covid-19 patients. METHODS: We retrospectively analyzed the admission 12-lead ECGs of 1124 consecutive patients hospitalized for respiratory distress and Covid-19 in a single III-level hospital. Age, gender, main clinical data and in-hospital survival were recorded. RESULTS: 548 patients were hospitalized in IMU, 361 in RCU, 215 in ICU. Arrhythmias in general were less frequently found in RCU (16% vs 26%, p<0.001). Deaths occurred more frequently in ICU patients (43% vs 20-21%, p<0.001). After pooling predictors of mortality (age, intensity of care setting, heart rate, ST-elevation, QTc prolongation, Q-waves, right bundle branch block, and atrial fibrillation), the risk of in-hospital death can be estimated by using a derived score. Three zones of mortality risk can be identified: <5%, score <5 points; 5-50%, score 5-10, and >50%, score >10 points. The accuracy of the score assessed at ROC curve analysis was 0.791. CONCLUSIONS: ECG differences at admission can be found in Covid-19 patients according to different clinical settings and intensity of care. A simplified score derived from few clinical and ECG variables may be helpful in stratifying the risk of in-hospital mortality.

Arrhythmic myocarditis in an adolescent male: A unique presentation of multi-organ inflammatory syndrome (MIS-C).

Although children with Covid-19 generally present with mild symptoms or are often asymptomatic, there is increasing recognition of a delayed multi-organ inflammatory syndrome (MIS-C) following SARS-CoV-2 infection. We report the case of MIS-C associated arrhythmic myocarditis which recovered after anti-inflammatory therapy and immunoglobulin infusion.

Safety and heart rate changes in Covid-19 patients treated with Remdesivir.

OBJECTIVES: Limited data are available regarding the occurrence and the extent of cardiac rhythm disturbances in patients with COVID-19 treated with Remdesivir. METHODS: We present a case series of 52 patients who underwent daily electrocardiogram (ECG) examination after Remdesivir administration. RESULTS: Compared to baseline, a significant heart rate reduction was observed after initiation of Remdesivir; however, no case of severe bradycardia or arrhythmias leading to significant clinical complications or Remdesivir discontinuation occurred. Heart rate reduction was proportional to baseline heart rate values (r=0.75, p<0.001). By multivariate analysis, a less severe clinical presentation of Covid-19 (beta=0.47, p<0.01) was related to lower heart rate levels observed after Remdesivir administration. CONCLUSIONS: Despite a significant reduction in heart rate observed after Remdesivir administration, no severe cardiovascular toxicity was observed in Covid-19 patients, even in the case of cardiovascular comorbidities.

Prophylactic anticoagulation and aspirin therapy for hospitalized patients with COVID-19: a propensity score-matched analysis of the hope-COVID-19 registry

Aims No standard therapy is currently recommended for moderately ill Corona-virus-19 disease (COVID-19) patients. Potential benefit in terms of survival for anticoagulation were found only in this subset of patients. Aim of this study was to evaluate safety and efficacy of add-on antiplatelet therapy with aspirin over prophylactic anticoagulation (PAC) in COVID-19 hospitalized patients and its impact on survival. Methods and results 7824 consecutive patients with COVID-19 were enrolled in a multicentre-international prospective registry (HOPE-COVID-19). Clinical data and in-hospital complications, including mortality, were recorded. Study population included only patients treated with aspirin and/or PAC. A comparison of clinical outcomes between add-on antiplatelet therapy and PAC and patients treated with PAC only was performed using an adjusted analysis with propensity score (PS) matching. Of 7824 patients, 360 (4.6%) received PAC and aspirin and 2949 (37.6%) PAC only. Propensity-score matching yielded 298 patients from each group. Mean age was 73 ± 11 years, 67% were male, prevalence of hypertension and diabetes was 79% and 33%, respectively, and 7.5 % underwent invasive ventilation. In the propensity score-matched population, cumulative incidence curves of in-hospital mortality were lower in patients treated with PAC and Aspirin vs. PAC only (15% vs. 21%, Log Rank P = 0.01). At multivariable analysis in propensity matched population of COVID-19 patients, including age, sex, hypertension, diabetes, kidney failure and invasive ventilation, aspirin treatment was associated with lower risk of in-hospital mortality (HR: 0.62, CI: 95% 0.42–0.92, P = 0.018). Conclusions Add-on anti-platelet therapy with aspirin over PAC in COVID-19 hospitalized patients was associated with lower mortality risk in a propensity score matched population.

Antiplatelet therapy and outcome in COVID-19. Results from a multi-centre international prospective registry (HOPE-COVID)

Aims Standard therapy for Corona-virus-19 disease (COVID-19) is mainly developed for critical ill patients. Autopsy studies showed high prevalence of platelet-fibrin rich micro-thrombi in several organs. Aim of the study was to evaluate safety and efficacy of antiplatelet therapy (APT) in COVID-19 hospitalized patients and its impact on survival. Methods and results 7824 consecutive patients with COVID-19 were enrolled in a multicentre-international prospective registry (HOPE-COVID-19). Clinical data and in-hospital complications were recorded. Antiplatelet (AP) regimen, including aspirin and other antiplatelet drugs, was obtained for each patient. During hospitalization 730 (9%) patients received AP drugs with single (93%, n = 680) or dual APT (7%, n = 50). Patients treated with APT were older (74 ± 12 vs. 63 ± 17 years, P < 0.01), more frequently male (68% vs. 57%, P < 0.01) and had higher prevalence of diabetes (39% vs. 16%, P < 0.01). Patients treated with APT compared with no APT showed no differences in terms of in-hospital mortality (18% vs. 19%, P = 0.64, Log Rank P = 0.23), need of invasive ventilation (8.7% vs. 8.5%, P = 0.88), embolic events (2.9% vs. 2.5% P = 0.34) and bleeding (2.1% vs. 2.4%, P = 0.43) but shorter duration of mechanical ventilation (8 ± 5 vs. 11 ± 7 days, P = 0.01);however, when comparing patients with APT vs. no APT and no anticoagulation therapy, APT was associated with lower mortality rates (Log Rank P < 0.01, relative risk 0.79, 95% CI: 0.70–0.94). At multivariable analysis in-hospital APT was associated with a lower mortality risk (relative risk 0.39, 95% CI: 0.32–0.48, P < 0.01). Conclusions APT during hospitalization for COVID-19 could be associated with lower mortality risk and shorter duration of mechanical ventilation, without increased risk of bleeding.

Electrocardiographic findings and mortality in COVID-19 patients hospitalized in different clinical settings

Aims 12-lead electrocardiogram (ECG) still represents the first line approach for cardiovascular assessment even in patients with COVID-19. We therefore sought to describe and compare ECG findings in three different hospital settings: intensive care unit (ICU) (invasive ventilatory support), respiratory care unit (RCU) (non-invasive ventilatory support) and Covid-19 dedicated internal medicine unit (IMU) (oxygen supplement with or without high flow). Methods and results We retrospectively analysed the 12-lead ECGs of 1124 consecutive patients hospitalized for respiratory distress and COVID-19 in a single III level hospital. Age, gender, main clinical data and in-hospital survival were recorded. 548 patients were hospitalized in IMU, 361 in RCU, 215 in ICU. Arrhythmias in general were less frequently found in RCU (16% vs. 26%, P < 0.001). Deaths occurred more frequently in ICU patients (43% vs. 20–21%, P < 0.001). After pooling predictors of mortality (age, intensity of care setting, heart rate, ST-elevation, QTc prolongation, Q-waves, right bundle branch block, and atrial fibrillation), the risk of in-hospital death can be estimated by using a derived score. Three zones of mortality risk can be thus identified: <5%, score <5 points;5–50% score 5–10, and >50%, score >10 points. The accuracy of the score assessed at ROC curve analysis was 0.791. Conclusions ECG differences at admission con be found in COVID-19 patients according to different clinical settings and intensity of care. A simplified score derived from few clinical and ECG variables may predict in-hospital mortality with a good accuracy.

Incidence and management of adverse events among COVID-19 vaccination receipts with Brugada syndrome. Results from a multicentre-prospective European registry

Aims Patients with Brugada syndrome have an increased risk of life-threatening arrhythmias when experience fever. Therefore, a prompt treatment of non-steroidal anti-inflammatory drugs (NSAI) is suggested in these patients. COVID-19 vaccination can be associated with fever in about 20% of patients. The aim of the study is to evaluate the incidence and management of adverse events within 48 h from COVID-19 vaccination among Brugada patients. Methods and results Eighty patients were enrolled from a prospective registry involving four European hospitals with a dedicated inherited disease ambulatory. Cardiological follow-up was performed within one month from vaccination. Mean age was 47 ± 17 years, 80% (num = 63) were male. Prevalence of Brugada types 1, 2, and 3 was as follows: 25% type 1, 39% type 2, and 24% type 3. Twenty-six percent of patients had an implantable cardioverter defibrillator (ICD). Within in 48 h from vaccination, 35% (num = 28) of patients experienced joint paint, 19% (num = 15) fever and 4% (num = 3) chest pain. In 8 out of 15 fever episodes body temperature was ≥38 degrees and treated with NSAI drugs. No patients had syncope or fatigue episodes and no arrhythmic episodes were recorded in patients with ICD. Conclusions About 20% of patients experienced fever after Covid-19 vaccination but no patient experienced life-threatening arrhythmias. Careful evaluation of body temperature and administration of NSAI in case of temperature higher than 38 is suggested.

QTc Interval Prolongation and Life-Threatening Arrhythmias During Hospitalization in Patients With Coronavirus Disease 2019 (COVID-19): Results From a Multicenter Prospective Registry.

BACKGROUND: Prolonged QTc intervals and life-threatening arrhythmias (LTA) are potential drug-induced complications previously reported with antimalarials, antivirals, and antibiotics. Our objective was to evaluate the prevalence and predictors of QTc interval prolongation and incidences of LTA during hospitalization for coronavirus disease 2019 (COVID-19) among patients with normal admission QTc. METHODS: We enrolled 110 consecutive patients in a multicenter international registry. A 12-lead electrocardiograph was performed at admission, after 7, and at 14 days; QTc values were analyzed. RESULTS: After 7 days, 15 (14%) patients developed a prolonged QTc (pQTc; mean QTc increase 66 ± 20 msec; +16%; P < .001); these patients were older and had higher basal heart rates, higher rates of paroxysmal atrial fibrillation, and lower platelet counts. The QTc increase was inversely proportional to the baseline QTc level and leukocyte count and directly proportional to the basal heart rate (P < .01).We conducted a multivariate stepwise analysis including age, male gender, paroxysmal atrial fibrillation, basal QTc values, basal heart rate, and dual antiviral therapy; age (odds ratio [OR], 1.06; 95% confidence interval [CI], 1.00-1.13; P < .05), basal heart rate (OR, 1.07; 95% CI, 1.02-1.13; P < .01), and dual antiviral therapy (OR, 12.46; 95% CI, 2.09-74.20; P < .1) were independent predictors of QT prolongation.The incidence rate of LTA during hospitalization was 3.6%. There was 1 patient who experienced cardiac arrest and 3 with nonsustained ventricular tachycardia. LTAs were recorded after a median of 9 days from hospitalization and were associated with 50% of the mortality rate. CONCLUSIONS: After 7 days of hospitalization, 14% of patients with COVID-19 developed pQTc; age, basal heart rate, and dual antiviral therapy were found to be independent predictors of pQTc. Life-threatening arrhythmias have an incidence rate of 3.6%, and were associated with a poor outcome.

[Italian Society of Cardiology (SIC) Position paper: Technical, instrumental and standards of interpretation for electrocardiography, ambulatory electrocardiographic and blood pressure monitoring in telemedicine]. / Position paper della Società Italiana di Cardiologia (SIC): Requisiti tecnici, strumentali e di refertazione per elettrocardiografia a riposo, monitoraggio elettrocardiografico ambulatoriale secondo Holter, monitoraggio ambulatoriale della pressione arteriosa in telemedicina.

The current COVID-19 pandemic has renewed interest in providing healthcare services based on the implementation of innovative technologies. Such strategy capillarizes the therapeutic opportunities for larger urban areas, mostly when people are living under extraordinarily difficult circumstances. Improving care delivery in cardiovascular diseases appears particularly feasible when telemedicine is pursued, especially with regard to baseline standard 12-lead electrocardiography, ambulatory electrocardiographic monitoring, and 24-hour ambulatory blood pressure monitoring. Nowadays, these first-line cardiovascular examinations are also available in health centers and pharmacies, and in recent months, there has been an increasing demand of such local services in the absence of specific rules and regulations regarding technical requirements and standards of interpretation that ensure a high quality clinical consultation.The purpose of this position paper is to provide critical requirements for the type/model of devices to be used, training dedicated to healthcare personnel, ensuring security of sensitive data, highlighting type of platforms to be used, as well as for maintaining high reporting quality and standards.

Antiplatelet therapy and outcome in COVID-19: the Health Outcome Predictive Evaluation Registry.

BACKGROUND: Standard therapy for COVID-19 is continuously evolving. Autopsy studies showed high prevalence of platelet-fibrin-rich microthrombi in several organs. The aim of the study was therefore to evaluate the safety and efficacy of antiplatelet therapy (APT) in hospitalised patients with COVID-19 and its impact on survival. METHODS: 7824 consecutive patients with COVID-19 were enrolled in a multicentre international prospective registry (Health Outcome Predictive Evaluation-COVID-19 Registry). Clinical data and in-hospital complications were recorded. Data on APT, including aspirin and other antiplatelet drugs, were obtained for each patient. RESULTS: During hospitalisation, 730 (9%) patients received single APT (93%, n=680) or dual APT (7%, n=50). Patients treated with APT were older (74±12 years vs 63±17 years, p<0.01), more frequently male (68% vs 57%, p<0.01) and had higher prevalence of diabetes (39% vs 16%, p<0.01). Patients treated with APT showed no differences in terms of in-hospital mortality (18% vs 19%, p=0.64), need for invasive ventilation (8.7% vs 8.5%, p=0.88), embolic events (2.9% vs 2.5% p=0.34) and bleeding (2.1% vs 2.4%, p=0.43), but had shorter duration of mechanical ventilation (8±5 days vs 11±7 days, p=0.01); however, when comparing patients with APT versus no APT and no anticoagulation therapy, APT was associated with lower mortality rates (log-rank p<0.01, relative risk 0.79, 95% CI 0.70 to 0.94). On multivariable analysis, in-hospital APT was associated with lower mortality risk (relative risk 0.39, 95% CI 0.32 to 0.48, p<0.01). CONCLUSIONS: APT during hospitalisation for COVID-19 could be associated with lower mortality risk and shorter duration of mechanical ventilation, without increased risk of bleeding. TRIAL REGISTRATION NUMBER: NCT04334291.

Anticoagulation Therapy in Patients With Coronavirus Disease 2019: Results From a Multicenter International Prospective Registry (Health Outcome Predictive Evaluation for Corona Virus Disease 2019 [HOPE-COVID19]).

OBJECTIVES: No standard therapy, including anticoagulation regimens, is currently recommended for coronavirus disease 2019. Aim of this study was to evaluate the efficacy of anticoagulation in coronavirus disease 2019 hospitalized patients and its impact on survival. DESIGN: Multicenter international prospective registry (Health Outcome Predictive Evaluation for Corona Virus Disease 2019). SETTING: Hospitalized patients with coronavirus disease 2019. PATIENTS: Five thousand eight hundred thirty-eight consecutive coronavirus disease 2019 patients. INTERVENTIONS: Anticoagulation therapy, including prophylactic and therapeutic regimens, was obtained for each patient. MEASUREMENTS AND MAIN RESULTS: Five thousand four hundred eighty patients (94%) did not receive any anticoagulation before hospitalization. Two-thousand six-hundred one patients (44%) during hospitalization received anticoagulation therapy and it was not associated with better survival rate (81% vs 81%; p = 0.94) but with higher risk of bleeding (2.7% vs 1.8%; p = 0.03). Among patients admitted with respiratory failure (49%, n = 2,859, including 391 and 583 patients requiring invasive and noninvasive ventilation, respectively), anticoagulation started during hospitalization was associated with lower mortality rates (32% vs 42%; p < 0.01) and nonsignificant higher risk of bleeding (3.4% vs 2.7%; p = 0.3). Anticoagulation therapy was associated with lower mortality rates in patients treated with invasive ventilation (53% vs 64%; p = 0.05) without increased rates of bleeding (9% vs 8%; p = 0.88) but not in those with noninvasive ventilation (35% vs 38%; p = 0.40). At multivariate Cox' analysis mortality relative risk with anticoagulation was 0.58 (95% CI, 0.49-0.67) in patients admitted with respiratory failure, 0.50 (95% CI, 0.49-0.67) in those requiring invasive ventilation, 0.72 (95% CI, 0.51-1.01) in noninvasive ventilation. CONCLUSIONS: Anticoagulation therapy in general population with coronavirus disease 2019 was not associated with better survival rates but with higher bleeding risk. Better results were observed in patients admitted with respiratory failure and requiring invasive ventilation.

Infection, atherothrombosis and thromboembolism beyond the COVID-19 disease: what similar in physiopathology and researches.

The recent Sars-Cov-2 pandemic (COVID-19) has led to growing research on the relationship between thromboembolism and Sars-Cov-2 infection. Nowadays, endothelial dysfunction, platelet activation, coagulation, and inflammatory host immune response are the subject of extensive researches in patients with COVID-19 disease. However, studies on the link between microorganisms or infections and thrombotic or thromboembolic events met fluctuating interest in the past. We, therefore, aimed to briefly summarize previous evidence on this topic, highlighting common points between previous data and what experienced today with SARS-COV2 infections.

Impact of 2020 SARS-CoV-2 outbreak on telemedicine management of cardiovascular disease in Italy.

The Covid-19 pandemic affected large part of Italy since February 2020; we, therefore, aimed to assess the impact of 2020 SARS-CoV-2 outbreak on telemedicine management of cardiovascular disease (CVD) in Italy. We analyzed data from three telemedicine dispatch centers, one located in Genoa, serving private clients (pharmacies, general practitioners), one in Brescia, serving pharmacies, and one in Bari, serving regional public STEMI network and emergency medical service in Apulia (4 million inhabitants). Demographic data and principal electrocardiogram diagnosis were collected and analyzed. Records from the time interval March 1, 2020 and April 1, 2020 were compared with the corresponding period in 2019. The comparative analysis of data shows a 54% reduction of telemedicine electrocardiogram transmission in Genoa telemedicine center (from 364 to 166), 68% in Brescia (from 5.745 to 1.905), 24% in Bari (from 15.825 to 11.716); relative reduction according to electrocardiogram diagnosis was 38% for acute coronary syndrome, 40% for other acute CVD in Genoa center, 24% for acute coronary syndrome, and 38% for other acute CVD in Bari. Male/female ratio remained substantially unchanged. A dramatic reduction of telemedicine access for CVD was observed during Covid-19 outbreak in March 2020 in Italy. The reduction was substantially consistent for all electrocardiogram findings, ACS, other acute CVD and normal.
