Association of Use and Dose of Lipid-Lowering Therapy Post Acute Myocardial Infarction With 5-Year Survival in Older Adults

BACKGROUND

Older people are underrepresented in randomized trials. The association between lipid-lowering therapy (LLT) and its intensity after acute myocardial infarction and long-term mortality in this population deserves to be assessed.

METHODS

The FAST-MI (French Registry of Acute ST-Elevation or Non-ST-Elevation Myocardial Infarction) program consists of nationwide French surveys including all patients admitted for acute myocardial infarction ≤48 hours from onset over a 1- to 2-month period in 2005, 2010, and 2015, with long-term follow-up. Numerous data were collected and a centralized 10-year follow-up was organized. The present analysis focused on the association between prescription of LLT (atorvastatin ≥40 mg or equivalent, or any combination of statin and ezetimibe) and 5-year mortality in patients aged ≥80 years discharged alive. Cox multivariable analysis and propensity score matching were used to adjust for baseline differences.

RESULTS

Among the 2258 patients aged ≥80 years (mean age, 85±4 years; 51% women; 39% ST-segment elevation myocardial infarction; 58% with percutaneous coronary intervention), 415 were discharged without LLT (18%), 866 with conventional doses (38%), and 977 with high-dose LLT (43%). Five-year survival was 36%, 47.5%, and 58%, respectively. Compared with patients without LLT, high-dose LLT was significantly associated with lower 5-year mortality (adjusted hazard ratio, 0.78 [95% CI, 0.66-0.92]), whereas conventional-intensity LLT was not (adjusted hazard ratio, 0.93 [95% CI, 0.80-1.09]). In propensity score-matched cohorts (n=278 receiving high-intensity LLT and n=278 receiving no statins), 5-year survival was 52% with high-intensity LLT at discharge and 42% without statins (hazard ratio, 0.78 [95% CI, 0.62-0.98]).

CONCLUSIONS

In these observational cohorts, high-intensity LLT at discharge after acute myocardial infarction was associated with reduced all-cause mortality at 5 years in an older adult population. These results suggest that high-intensity LLT should not be denied to patients on the basis of old age.

Molecular genetic screening after non-ischaemic sudden cardiac arrest and no overt cardiomyopathy in real life: A major tool for the aetiological diagnostic work-up

BACKGROUND

With the development of advanced sequencing techniques, genetic testing has emerged as a valuable tool for the work-up of non-ischaemic sudden cardiac arrest (SCA).

AIMS

To evaluate the effectiveness of genetic testing in patients with unexplained SCA, according to clinical phenotype.

METHODS

All patients who underwent molecular genetic testing for non-ischaemic SCA with no left ventricular cardiomyopathy between 2012 and 2021 in two French university hospitals were included.

RESULTS

Of 66 patients (mean age 36.7±11.9years, 54.5% men), 21 (31.8%; 95% confidence interval 22.4-45.3%) carried a genetic variant: eight (12.1%) had a pathogenic or likely pathogenic (P/LP) variant and 13 (19.7%) had a variant of uncertain significance (VUS). Among 37 patients (56.1%) with no phenotypic clues, genetic testing identified a P/LP variant in five (13.5%), mainly in RYR2 (n=3) and SCN5A (n=2), and a VUS in nine (24.3%). None of the nine patients with phenotypic evidence of channelopathies had P/LP variants, but two had VUS in RYR2 and NKX2.5. Among the 20 patients with suspected arrhythmogenic cardiomyopathy, three P/LP variants (15.0%) and two VUS (10.0%) were found in DSC2, PKP2, SCN5A and DSG2, TRPM4, respectively. Genetic testing was performed sooner after cardiac arrest (P<0.001) and results were obtained more rapidly (P=0.02) after versus before 2016.

CONCLUSION

This study highlights the utility of molecular genetic testing with a genetic variant of interest identified in one-third of patients with unexplained SCA. Genetic testing was beneficial even in patients without phenotypic clues, with one-fourth of patients carrying a P/LP variant that could have direct implications.

Very long-term outcomes after acute myocardial infarction in young men and women: Insights from the FAST-MI program

AIMS

Conflicting data exists about long-term outcomes in young women and men experiencing acute myocardial infarction (AMI).

METHODS

The FAST-MI program consists of three nationwide French surveys carried out 5years apart from 2005 to 2015, including consecutive patients with AMI over a 1-month period with up to 10-year follow-up. The present analysis focused on adults≤50 yo according to their gender.

RESULTS

Women accounted for 17.5% (335) of the 1912 patients under 50 yo and had a similar age as men (43.9±5.1 vs. 43.9±5.5years, P=0.92). They received less percutaneous coronary interventions (PCI) than men (85.9% vs. 91.3%, P=0.005), even in ST-elevation myocardial infarction (83.6% vs. 93.5%, P<0.001). Recommended secondary prevention medications were less frequently prescribed at discharge in women (40.6% vs. 52.8%, P<0.001), a trend that persisted in 2015 (59.1% vs. 72.8% in 2015, P<0.001). Still, ten-year survival was similar in men (90.5%) and women (92.3%) (crude HR: 0.86 [95% CI: 0.55-1.35], P=0.52, adjusted HR: 0.63 [95% CI: 0.38-1.07], P=0.09); similar results were found for ten-year survival among hospital survivors (91.2% in men vs. 93.7% in women, adjusted HR: 0.87 [95% CI: 0.45-1.66], P=0.66). Of the 1684 patients alive at hospital discharge with morbidity follow-up≥6months available, death, AMI or stroke at 8years occurred in 12.9% men and 11.2% in women (adjusted HR: 0.90 [95% CI: 0.60-1.33], P=0.59).

CONCLUSIONS

Young women with AMI undergo less cardiac interventions and are less often prescribed secondary prevention treatment than men, even when significant coronary artery disease is present, but keep a similar long-term prognosis after AMI. Optimal management of these young patients, regardless of gender, is necessary to ensure best outcomes after this major cardiovascular event.

Impact of peri-procedural management of direct oral anticoagulants on pocket haematoma after cardiac electronic device implantation: the StimAOD multicentre prospective study

AIMS

The study aims to investigate the impact of direct oral anticoagulant (DOAC) management on the incidence of pocket haematoma in patients undergoing pacemaker or implantable cardioverter-defibrillator implantation.

METHODS AND RESULTS

All consecutive patients receiving DOAC and undergoing cardiac electronic device implantation were included in a large multicentre prospective observational study (NCT03879473). The primary endpoint was clinically relevant haematoma within 30 days after implantation. Overall, 789 patients were enrolled [median age 80 (IQR 72-85) years old, 36.4% women, median CHA2DS2-VASc score 4 (IQR 0-8)], of which 632 (80.1%) received a pacemaker implantation. Antiplatelet therapy was combined with DOAC in 146 patients (18.5%). Direct oral anticoagulants (DOACs) were interrupted 52 (IQR 37-62) h before the procedure and resumed 31 (IQR 21-47) h later. Ninety-six percent of the patients had at least 12 h DOAC interruption before the procedure, and 78% had at least 12 h DOAC interruption after the procedure. Overall, anticoagulation was interrupted for 72 (IQR 48-96) h. Pre- or post-procedural heparin bridging was used in 8.2% and 3.9%, respectively. Timing of DOAC interruption of resumption was not associated with clinically relevant haematoma. Clinically relevant haematoma occurred in 26 patients (3.3%), and thromboembolic events occurred in 5 patients (0.6%).

CONCLUSION

In this large real-life registry where most patients had DOAC interruption, clinically relevant haematoma was rare. Despite DOAC interruption and high CHA2DS2-VASc score, thromboembolic events occurred seldomly, highlighting that bleeding exceeds thromboembolic risk in this peri-procedural period. Future research is needed to identify risk factors for clinically relevant haematoma and meaningfully guide clinicians in optimizing DOAC management.

Incidence of Cardiac Arrest During Sports Among Women in the European Union

BACKGROUND

Women represent a growing proportion of sports participants. Still, few original data regarding sudden cardiac arrest during sports (Sr-SCA) in women are available.

OBJECTIVES

The authors sought to assess the incidence, characteristics, and outcomes of women presenting with Sr-SCA.

METHODS

Data were analyzed from 3 population-based European registries (ESCAPE-NET 2020 Horizon Program) that prospectively and exhaustively collect every case of SCA: SDEC (Paris-Sudden Death Expertise Center), ARREST (AmsteRdam REsuscitation Studies), and SRCR (Swedish Register for Cardiopulmonary Resuscitation). Sr-SCA was defined as SCA during or ≤1 hour after cessation of sports activity.

RESULTS

Of 34,826 SCA between 2006 and 2017, 760 Sr-SCA (2.2%) were identified, including 54 in women. The average annual incidence of Sr-SCA in women in the 3 registries ranged from 0.10 per million (95% CI: 0.01-0.71 per million) to 0.38 per million (95% CI: 0.14-1.04 per million). Overall, the average annual incidence rate of Sr-SCA in women was 0.19 per million (95% CI: 0.14-0.24 per million), >10-fold lower compared with men (2.63 per million [95% CI: 2.45-2.83 per million]; P < 0.0001). When extrapolating to the total European population and accounting for age and sex, this yields 98 cases per year (95% CI: 72-123 cases per year) in women and 1,350 cases per year (95% CI: 1,256-1,451 cases per year) in men. Subject characteristics and circumstances of occurrence were similar in women vs men. Bystander response, time to defibrillation, and survival rate at hospital admission (58.8% vs 58.5%; P = 0.99) and 30 days did not differ significantly between women and men.

CONCLUSIONS

These findings emphasize the dramatically lower risk of Sr-SCA in women compared with men, despite similar subject characteristics. This should be considered in designing preparticipation screening strategies in the future.

Machine learning-based scoring system to predict in-hospital outcomes in patients hospitalized with COVID-19

BACKGROUND

The evolution of patients hospitalized with coronavirus disease 2019 (COVID-19) is still hard to predict, even after several months of dealing with the pandemic.

AIMS

To develop and validate a score to predict outcomes in patients hospitalized with COVID-19.

METHODS

All consecutive adults hospitalized for COVID-19 from February to April 2020 were included in a nationwide observational study. Primary composite outcome was transfer to an intensive care unit from an emergency department or conventional ward, or in-hospital death. A score that estimates the risk of experiencing the primary outcome was constructed from a derivation cohort using stacked LASSO (Least Absolute Shrinkage and Selection Operator), and was tested in a validation cohort.

RESULTS

Among 2873 patients analysed (57.9% men; 66.6±17.0 years), the primary outcome occurred in 838 (29.2%) patients: 551 (19.2%) were transferred to an intensive care unit; and 287 (10.0%) died in-hospital without transfer to an intensive care unit. Using stacked LASSO, we identified 11 variables independently associated with the primary outcome in multivariable analysis in the derivation cohort (n=2313), including demographics (sex), triage vitals (body temperature, dyspnoea, respiratory rate, fraction of inspired oxygen, blood oxygen saturation) and biological variables (pH, platelets, C-reactive protein, aspartate aminotransferase, estimated glomerular filtration rate). The Critical COVID-19 France (CCF) risk score was then developed, and displayed accurate calibration and discrimination in the derivation cohort, with C-statistics of 0.78 (95% confidence interval 0.75-0.80). The CCF risk score performed significantly better (i.e. higher C-statistics) than the usual critical care risk scores.

CONCLUSIONS

The CCF risk score was built using data collected routinely at hospital admission to predict outcomes in patients with COVID-19. This score holds promise to improve early triage of patients and allocation of healthcare resources.

Sports-related sudden cardiac arrest in young adults

AIMS

Data on sports-related sudden cardiac arrest (SrSCA) among young adults in the general population are scarce. We aimed to determine the overall SrSCA incidence, characteristics, and outcomes in young adults.

METHODS AND RESULTS

Prospective cohort study of all cases of SrSCA between 2012 and 2019 in Germany and Paris area, France, involving subjects aged 18-35 years. Detection of SrSCA was achieved via multiple sources, including emergency medical services (EMS) reporting and web-based screening of media releases. Cases and aetiologies were centrally adjudicated. Overall, a total of 147 SrSCA (mean age 28.1 ± 4.8 years, 95.2% males) occurred, with an overall burden of 4.77 [95% confidence interval (CI) 2.85-6.68] cases per million-year, including 12 (8.2%) cases in young competitive athletes. While bystander cardiopulmonary resuscitation (CPR) was initiated in 114 (82.6%), automated external defibrillator (AED) use by bystanders occurred only in a minority (7.5%). Public AED use prior to EMS arrival (odds ratio 6.25, 95% CI 1.48-43.20, P = 0.02) was the strongest independent predictor of survival at hospital discharge (38.1%). Among cases that benefited from both immediate bystander CPR and AED use, survival rate was 90.9%. Coronary artery disease was the most frequent aetiology (25.8%), mainly through acute coronary syndrome (86.9%).

CONCLUSION

Sports-related sudden cardiac arrest in the young occurs mainly in recreational male sports participants. Public AED use remains disappointingly low, although survival may reach 90% among those who benefit from both bystander CPR and early defibrillation. Coronary artery disease is the most prevalent cause of SrSCA in young adults.

Very long-term outcomes after acute myocardial infarction in young men and women

Aims

There is a paucity of data on very long-term outcomes in young women and men experiencing acute myocardial infarction (AMI).

Methods and results

The FAST-MI program consists of three nationwide French surveys carried out 5 years apart from 2005 to 2015, including consecutive AMI patients over a 1-month period with up to 10-year follow-up. The present analysis focused on adults ≤50 yo according to their gender. Women accounted for 17.5% (N=335) of the 1912 patients under 50 yo and were as old as men (43.9±5.5 vs. 43.9±5.1yo, p=0.92). Non-significant coronary artery disease was more frequent in women (12.8% vs. 5.8%, P&lt;0.001). Women with significant coronary artery disease underwent less percutaneous coronary internvention (PCI) than men (85.9% vs. 91.3%, p=0.005), though primary PCI in ST-elevated myocardial infarction was as frequent in women (67.3% vs. 66.8%). Recommended secondary prevention medications were less prescribed at discharge in women (40.6% vs. 52.8%, p&lt;0.001), a trend that persisted in 2015 (59.1% vs. 72.8% in 2015, p&lt;0.001). Still, ten-year survival was similar in men (90.5%) and women (92.6%) (crude HR 0.87 [95% CI 0.55–1.57], adjusted HR 0.77 [95% CI 0.48–1.23], p=0.27) even among hospital survivors (adjusted HR 0.64 [95% CI 0.32–1.30], p=0.22). Ten-year survival was similar in patients with myocardial infarction with non-obstructive coronary arteries compared with those with significant coronary artery disease (91.8% vs. 91.0%, P=0.46)), both among men (91.6% vs. 90.7%) and women (92.9% vs. 93.0%). However, when taking into account early revascularization and discharge medications, in patients with significant coronary artery disease, adjusted 10-year mortality was significantly lower in women (HR 0.53, 95% CI 0.29–0.96, P=0.04).

Conclusions

Ten-year survival in young women with AMI is similar to that of men. However, in those with significant coronary artery disease, improving secondary prevention in women should result in better long-term outcome.

Ventricular fibrillation complicating acute myocardial infarction in women

Background

Very little data is available in women presenting with ventricular fibrillation in the setting of acute myocardial infarction.

Purpose

To investigate sex-discrepancies in the incidence, characteristics and outcomes of acute myocardial infarction complicated by ventricular fibrillation.

Methods

Data were analyzed from the FAST-MI registry, which prospectively included 14,406 patients with acute myocardial infarction (mean age 66±14 years, 72% male, mean left ventricular ejection fraction 52±12%, 59% with ST elevation myocardial infarction). All consecutive patients admitted to French cardiac intensive care units ≤48 hours from acute myocardial infarction onset during a 1-month period every five years during 1995 and 2015 were included. This analysis focused on ventricular fibrillation occurring during the initial in-hospital stay for acute myocardial infarction in women compared to men.

Results

A total of 359 patients developed ventricular fibrillation during acute myocardial infarction, including 81 women (2.0% of 4,091 women overall) and 278 men (2.7% of 10,315) (p=0.02). ST-elevation myocardial infarction (OR 2.29, 95% CI 1.75–2.99, p&lt;0.001) was independently associated with occurrence of ventricular fibrillation, while female gender (OR 0.73, 95% CI 0.56–0.95, p=0.02), hypertension (OR 0.75, 95% CI 0.60–0.94, p=0.01) and prior MI (OR 0.69, 95% CI 0.50–0.96, p=0.03) were protective factors. Women were less likely to have percutaneous coronary intervention during hospitalization than men (48.1% vs. 69.1%, OR 0.48, 95% CI 0.29–0.80, p&lt;0.001). One-year mortality was higher in women compared to men (23.1% vs. 7.0%, HR 5.5, 95% CI 1.7–17.2, p=0.001). However, after adjustment for age, type of myocardial infarction and percutaneous coronary intervention, female gender was no longer associated with a worse one-year mortality (adjusted HR 1.04, 95% CI 0.71–1.51, p=0.85).

Conclusion and relevance

Women have lower risk of developing ventricular fibrillation during acute myocardial infarction compared to men. However, they are less likely to receive early coronary interventions than men, possibly contributing to worse outcomes.

D-dimer, BNP/NT-pro-BNP, and creatinine are reliable decision-making biomarkers in life-sustaining therapies withholding and withdrawing during COVID-19 outbreak

Background

The decision for withholding and withdrawing of life-sustaining treatments (LSTs) in COVID-19 patients is currently based on a collegial and mainly clinical assessment. In the context of a global pandemic and overwhelmed health system, the question of LST decision support for COVID-19 patients using prognostic biomarkers arises.

Methods

In a multicenter study in 24 French hospitals, 2878 COVID-19 patients hospitalized in medical departments from 26 February to 20 April 2020 were included. In a propensity-matched population, we compared the clinical, biological, and management characteristics and survival of patients with and without LST decision using Student's t-test, the chi-square test, and the Cox model, respectively.

Results

An LST was decided for 591 COVID-19 patients (20.5%). These 591 patients with LST decision were secondarily matched (1:1) based on age, sex, body mass index, and cancer history with 591 COVID-19 patients with no LST decision. The patients with LST decision had significantly more cardiovascular diseases, such as high blood pressure (72.9 vs. 66.7%, p = 0.02), stroke (19.3 vs. 11.1%, p < 0.001), renal failure (30.4 vs. 17.4%, p < 0.001), and heart disease (22.5 vs. 14.9%, p < 0.001). Upon admission, LST patients were more severely attested by a qSOFA score ≥2 (66.5 vs. 58.8%, p = 0.03). Biologically, LST patients had significantly higher values of D-dimer, markers of heart failure (BNP and NT-pro-BNP), and renal damage (creatinine) (p < 0.001). Their evolutions were more often unfavorable (in-hospital mortality) than patients with no LST decision (41.5 vs. 10.3%, p < 0.001). By combining the three biomarkers (D-dimer, BNP and/or NT-proBNP, and creatinine), the proportion of LST increased significantly with the number of abnormally high biomarkers (24, 41.3, 48.3, and 60%, respectively, for none, one, two, and three high values of biomarkers, trend p < 0.01).

Conclusion

The concomitant increase in D-dimer, BNP/NT-proBNP, and creatinine during the admission of a COVID-19 patient could represent a reliable and helpful tool for LST decision. Circulating biomarker might potentially provide additional information for LST decision in COVID-19.

Incidence, Characteristics, and Outcomes of Ventricular Fibrillation Complicating Acute Myocardial Infarction in Women Admitted Alive in the Hospital

Background

Little data are available in women presenting with ventricular fibrillation (VF) in the setting of acute myocardial infarction (AMI). We assessed frequency, predictors of VF, and outcomes, with a special focus on women compared with men.

Methods and Results

Data were analyzed from the FAST‐MI (French Registry of Acute ST‐Elevation or Non‐ST‐Elevation Myocardial Infarction) program, which prospectively included 14 406 patients admitted to French cardiac intensive care units ≤48 hours from AMI onset between 1995 and 2015 (mean age, 66±14 years; 72% men; mean left ventricular ejection fraction, 52±12%; 59% with ST‐segment–elevation myocardial infarction). A total of 359 patients developed VF during AMI, including 81 women (2.0% of 4091 women) and 278 men (2.7% of 10 315 men, P=0.02). ST‐segment–elevation myocardial infarction (odds ratio [OR], 2.29 [95% CI, 1.75–2.99]; P<0.001) was independently associated with the onset of VF during AMI. In contrast, female sex (OR, 0.73 [95% CI, 0.56–0.95]; P=0.02), hypertension (OR, 0.75 [95% CI, 0.60–0.94]; P=0.01), and prior myocardial infarction (OR, 0.69 [95% CI, 0.50–0.96]; P=0.03) were protective factors. Women were less likely to have cardiac intervention than men (percutaneous coronary intervention during hospitalization 48.1% versus 66.9%, respectively; P=0.04) with a higher 1‐year mortality in women compared with men (50.6% versus 37.4%, respectively; P=0.03), including increased in‐hospital mortality (42.0% versus 32.7%, respectively; P=0.12). After adjustment, female sex was no longer associated with a worse 1‐year mortality (adjusted hazard ratio, 1.10 [95% CI, 0.75–1.61]; P=0.63).

Conclusions

Women have lower risk of developing VF during AMI compared with men. However, they are less likely to receive cardiac interventions than men, possibly contributing to missed opportunities of improved outcomes.

Cardiovascular manifestations secondary to COVID-19: A narrative review

The coronavirus disease 2019 (COVID-19) pandemic has spread rapidly, becoming a major threat to global health. In addition to having required the adaptation of healthcare workers for almost 2 years, it has been much talked about, both in the media and among the scientific community. Beyond lung damage and respiratory symptoms, the involvement of the cardiovascular system largely explains COVID-19 morbimortality. In this review, we emphasize that cardiovascular involvement is common and is associated with a worse prognosis, and that earlier detection by physicians should lead to better management. First, direct cardiac involvement will be discussed, in the form of COVID-19 myocarditis, then secondary cardiac involvement, such as myocardial injury, myocardial infarction and arrhythmias, will be considered. Finally, worsening of previous cardiovascular disease as a result of COVID-19 will be examined, as well as long-term COVID-19 effects and cardiovascular complications of COVID-19 vaccines.

Cardiovascular Characteristics and Outcomes of Young Patients with COVID-19

Although 18–45-year-old (y-o) patients represent a significant proportion of patients hospitalized for COVID-19, data concerning the young population remain scarce. The Critical COVID France (CCF) study was an observational study including consecutive patients hospitalized for COVID-19 in 24 centers between 26 February and 20 April 2020. The primary composite outcome included transfer to the intensive care unit (ICU) or in-hospital death. Secondary outcomes were cardiovascular (CV) complications. Among 2868 patients, 321 (11.2%) patients were in the 18–45-y-o range. In comparison with older patients, young patients were more likely to have class 2 obesity and less likely to have hypertension, diabetes and dyslipidemia. The primary outcome occurred less frequently in 18–45-y-o patients in comparison with patients > 45 years old (y/o) (16.8% vs. 30.7%, p < 0.001). The 18–45-y-o patients presented with pericarditis (2.2% vs. 0.5%, p = 0.003) and myocarditis (2.5% vs. 0.6%, p = 0.002) more frequently than patients >45 y/o. Acute heart failure occurred less frequently in 18–45-y-o patients (0.9% vs. 7.2%, p < 0.001), while thrombotic complications were similar in young and older patients. Whereas both transfer to the ICU and in-hospital death occurred less frequently in young patients, COVID-19 seemed to have a particular CV impact in this population.

Intermediate- vs. Standard-Dose Prophylactic Anticoagulation in Patients With COVID-19 Admitted in Medical Ward: A Propensity Score-Matched Cohort Study

Background: Microthrombosis and large-vessel thrombosis are the main triggers of COVID-19 worsening. The optimal anticoagulant regimen in COVID-19 patients hospitalized in medical wards remains unknown. Objectives: To evaluate the effects of intermediate-dose vs. standard-dose prophylactic anticoagulation (AC) among patients with COVID-19 hospitalized in medical wards. Methods and results: We used a large French multicentric retrospective study enrolling 2,878 COVID-19 patients hospitalized in medical wards. After exclusion of patients who had an AC treatment before hospitalization, we generated a propensity-score-matched cohort of patients who were treated with intermediate-dose or standard-dose prophylactic AC between February 26 and April 20, 2020 (intermediate-dose, n = 261; standard-dose prophylactic anticoagulation, n = 763). The primary outcome of the study was in-hospital mortality; this occurred in 23 of 261 (8.8%) patients in the intermediate-dose group and 74 of 783 (9.4%) patients in the standard-dose prophylactic AC group (p = 0.85); while time to death was also the same in both the treatment groups (11.5 and 11.6 days, respectively, p = 0.17). We did not observe any difference regarding venous and arterial thrombotic events between the intermediate dose and standard dose, respectively (venous thrombotic events: 2.3 vs. 2.4%, p=0.99; arterial thrombotic events: 2.7 vs. 1.2%, p = 0.25). The 30-day Kaplan-Meier curves for in-hospital mortality demonstrate no statistically significant difference in in-hospital mortality (HR: 0.99 (0.63-1.60); p = 0.99). Moreover, we found that no particular subgroup was associated with a significant reduction in in-hospital mortality. Conclusion: Among COVID-19 patients hospitalized in medical wards, intermediate-dose prophylactic AC compared with standard-dose prophylactic AC did not result in a significant difference in in-hospital mortality.

History of heart failure in patients with coronavirus disease 2019: Insights from a French registry

BACKGROUND

Although cardiovascular comorbidities seem to be strongly associated with worse outcomes in patients with coronavirus disease 2019 (COVID-19), data regarding patients with preexisting heart failure are limited.

AIMS

To investigate the incidence, characteristics and clinical outcomes of patients with COVID-19 with a history of heart failure with preserved or reduced ejection fraction.

METHODS

We performed an observational multicentre study including all patients hospitalized for COVID-19 across 24 centres in France from 26 February to 20 April 2020. The primary endpoint was a composite of in-hospital death or need for orotracheal intubation.

RESULTS

Overall, 2809 patients (mean age 66.4±16.9years) were included. Three hundred and seventeen patients (11.2%) had a history of heart failure; among them, 49.2% had heart failure with reduced ejection fraction and 50.8% had heart failure with preserved ejection fraction. COVID-19 severity at admission, defined by a quick sequential organ failure assessment score>1, was similar in patients with versus without a history of heart failure. Before and after adjustment for age, male sex, cardiovascular comorbidities and quick sequential organ failure assessment score, history of heart failure was associated with the primary endpoint (hazard ratio [HR]: 1.41, 95% confidence interval [CI]: 1.06-1.90; P=0.02). This result seemed to be mainly driven by a history of heart failure with preserved ejection fraction (HR: 1.61, 95% CI: 1.13-2.27; P=0.01) rather than heart failure with reduced ejection fraction (HR: 1.19, 95% CI: 0.79-1.81; P=0.41).

CONCLUSIONS

History of heart failure in patients with COVID-19 was associated with a higher risk of in-hospital death or orotracheal intubation. These findings suggest that patients with a history of heart failure, particularly heart failure with preserved ejection fraction, should be considered at high risk of clinical deterioration.

Characteristics and impact of cardiovascular comorbidities on coronavirus disease 2019 in women: A multicentre cohort study

Background

Although women account for up to half of patients hospitalized for coronavirus disease 2019 (COVID-19), no specific data have been reported in this population.

Aims

To assess the burden and impact of cardiovascular comorbidities in women with COVID-19.

Methods

All consecutive patients hospitalized for COVID-19 across 24 hospitals from 26 February to 20 April 2020 were included. The primary composite outcome was transfer to an intensive care unit or in-hospital death.

Results

Among 2878 patients, 1212 (42.1%) were women. Women were older (68.3 ± 18.0 vs. 65.4 ± 16.0 years; P < 0.001), but had less prevalent cardiovascular comorbidities than men. Among women, 276 (22.8%) experienced the primary outcome, including 161 (13.3%) transfers to an intensive care unit and 115 (9.5%) deaths without transfer to intensive care unit. The rate of in-hospital death or transfer to an intensive care unit was lower in women versus men (crude hazard ratio [HR]: 0.62, 95% confidence interval [CI]: 0.53–0.72). Age (adjusted HR: 1.05 per 5-year increase, 95% CI: 1.01–1.10), body mass index (adjusted HR: 1.06 per 2-unit increase, 95% CI: 1.02–1.10), chronic kidney disease (adjusted HR: 1.57, 95% CI: 1.11–2.22) and heart failure (adjusted HR: 1.52, 95% CI: 1.04–2.22) were independently associated with the primary outcome in women. Elevated B-type natriuretic peptide/N-terminal prohormone of B-type natriuretic peptide (adjusted HR: 2.41, 95% CI: 1.70–3.44) and troponin (adjusted HR: 2.00, 95% CI: 1.39–2.88) concentrations at admission were also associated with the primary outcome, even in women free of previous coronary artery disease or heart failure.

Conclusions

Although female sex was associated with a lower risk of transfer to an intensive care unit or in-hospital death, COVID-19 remained associated with considerable morbimortality in women, especially in those with cardiovascular diseases.

Prognostic value of right ventricular dilatation in patients with COVID-19: a multicentre study

Aims

Although cardiac involvement has prognostic significance in coronavirus disease 2019 (COVID-19) and is associated with severe forms, few studies have explored the prognostic role of transthoracic echocardiography (TTE). We investigated the link between TTE parameters and prognosis in COVID-19.

Methods and results

Consecutive patients with COVID-19 admitted to 24 French hospitals were retrospectively included. Comprehensive data, including clinical and biological parameters, were recorded at admission. Focused TTE was performed during hospitalization, according to clinical indication. Patients were followed for a primary composite outcome of death or transfer to intensive care unit (ICU) during hospitalization. Among 2878 patients, 445 (15%) underwent TTE. Most of these had cardiovascular risk factors, a history of cardiovascular disease, and were on cardiovascular treatments. Dilatation and dysfunction were observed in, respectively, 12% (48/412) and 23% (102/442) of patients for the left ventricle, and in 12% (47/407) and 16% (65/402) for the right ventricle (RV). Primary composite outcome occurred in 44% (n = 196) of patients [9% (n = 42) for death without ICU transfer and 35% (n = 154) for admission to ICU]. RV dilatation was the only TTE parameter associated with the primary outcome. After adjustment, male sex [hazard ratio (HR) 1.56, 95% confidence interval (CI) 1.09 − 2.25; P = 0.02], higher body mass index (HR 1.10, 95% CI 1.02 − 1.18; P = 0.01), anticoagulation (HR 0.53, 95% CI 0.33 − 0.86; P = 0.01), and RV dilatation (HR 1.66, 95% CI 1.05 − 2.64; P = 0.03) remained independently associated with the primary outcome.

Conclusion

Echocardiographic evaluation of RV dilatation could be useful for assessing risk of severe COVID-19 developing in hospitalized patients.

[Fighting against unexplained sudden death]

Sudden cardiac death, mostly related to ventricular arrhythmia, is a major public health issue, with still very poor survival at hospital discharge. Although coronary artery disease remains the leading cause, other etiologies should be systematically investigated. Exhaustive and standardized exploration is required to eventually offer specific therapeutics and management to the patient as well as his/her family members in case of inherited cardiac disease. Identification and establishing direct causality of the detected cardiac anomaly may remain challenging, underlying the need for a multidisciplinary and experimented team.

D-dimer at hospital admission for COVID-19 are associated with in-hospital mortality, independent of venous thromboembolism: Insights from a French multicenter cohort study

Background

Coronavirus disease 2019 (COVID-19) has been associated with coagulation disorders, in particular high concentrations of D-dimer, and increased frequency of venous thromboembolism.

Aim

To explore the association between D-dimer at admission and in-hospital mortality in patients hospitalised for COVID-19, with or without symptomatic venous thromboembolism.

Methods

From 26 February to 20 April 2020, D-dimer concentration at admission and outcomes (in-hospital mortality and venous thromboembolism) of patients hospitalised for COVID-19 in medical wards were retrospectively analysed in a multicenter study in 24 French hospitals.

Results

Among 2878 patients enrolled in the study, 1154 (40.1%) patients had D-dimer measurement at admission. Receiver operating characteristic curve analysis identified a D-dimer concentration > 1128 ng/mL as the best cut-off value for in-hospital mortality (area under the curve 64.9%, 95% confidence interval [CI] 60–69), with a sensitivity of 71.1% (95% CI 62–78) and a specificity of 55.6% (95% CI 52–58), which did not differ in the subgroup of patients with venous thromboembolism during hospitalisation. Among 545 (47.2%) patients with D-dimer concentration > 1128 ng/mL at admission, 86 (15.8%) deaths occurred during hospitalisation. After adjustment, in Cox proportional hazards and logistic regression models, D-dimer concentration > 1128 ng/mL at admission was also associated with a worse prognosis, with an odds ratio of 3.07 (95% CI 2.05–4.69; P < 0.001) and an adjusted hazard ratio of 2.11 (95% CI 1.31–3.4; P < 0.01).

Conclusions

D-dimer concentration > 1128 ng/mL is a relevant predictive factor for in-hospital mortality in patients hospitalised for COVID-19 in a medical ward, regardless of the occurrence of venous thromboembolism during hospitalisation.

Characteristics and outcomes of patients hospitalized for COVID-19 in France: The Critical COVID-19 France (CCF) study

Background

The coronavirus disease 2019 (COVID-19) pandemic has led to a public health crisis. Only limited data are available on the characteristics and outcomes of patients hospitalized for COVID-19 in France.

Aims

To investigate the characteristics, cardiovascular complications and outcomes of patients hospitalized for COVID-19 in France.

Methods

The Critical COVID-19 France (CCF) study is a French nationwide study including all consecutive adults with a diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) infection hospitalized in 24 centres between 26 February and 20 April 2020. Patients admitted directly to intensive care were excluded. Clinical, biological and imaging parameters were systematically collected at hospital admission. The primary outcome was in-hospital death.

Results

Of 2878 patients included (mean ± SD age 66.6 ± 17.0 years, 57.8% men), 360 (12.5%) died in the hospital setting, of which 7 (20.7%) were transferred to intensive care before death. The majority of patients had at least one (72.6%) or two (41.6%) cardiovascular risk factors, mostly hypertension (50.8%), obesity (30.3%), dyslipidaemia (28.0%) and diabetes (23.7%). In multivariable analysis, older age (hazard ratio [HR] 1.05, 95% confidence interval [CI] 1.03 − 1.06; P < 0.001), male sex (HR 1.69, 95% CI 1.11 − 2.57; P = 0.01), diabetes (HR 1.72, 95% CI 1.12 − 2.63; P = 0.01), chronic kidney failure (HR 1.57, 95% CI 1.02 − 2.41; P = 0.04), elevated troponin (HR 1.66, 95% CI 1.11 − 2.49; P = 0.01), elevated B-type natriuretic peptide or N-terminal pro-B-type natriuretic peptide (HR 1.69, 95% CI 1.0004 − 2.86; P = 0.049) and quick Sequential Organ Failure Assessment score ≥ 2 (HR 1.71, 95% CI 1.12 − 2.60; P = 0.01) were independently associated with in-hospital death.

Conclusions

In this large nationwide cohort of patients hospitalized for COVID-19 in France, cardiovascular comorbidities and risk factors were associated with a substantial morbi-mortality burden.

COVID-19 severity in kidney transplant recipients is similar to nontransplant patients with similar comorbidities

Higher rates of severe COVID-19 have been reported in kidney transplant recipients (KTRs) compared to nontransplant patients. We aimed to determine if poorer outcomes were specifically related to chronic immunosuppression or underlying comorbidities. We used a 1:1 propensity score-matching method to compare survival and severe disease-free survival (defined as death and/or need for intensive care unit [ICU]) incidence in hospitalized KTRs and nontransplant control patients between February 26 and May 22, 2020. Patients were matched for risk factors of severe COVID-19: age, sex, body mass index, diabetes mellitus, preexisting cardiopathy, chronic lung disease, and basal renal function. We included 100 KTRs (median age [interquartile range (IQR)]) 64.7 years (55.3-73.1) in three French transplant centers. After a median follow-up of 13 days (7-30), transfer to ICU was required for 34 patients (34%) and death occurred in 26 patients (26%). Overall, 43 patients (43%) developed a severe disease during a median follow-up of 8.5 days (2-14). Propensity score matching to a large French cohort of 2017 patients hospitalized in 24 centers, revealed that survival was similar between KTRs and matched nontransplant patients with respective 30-day survival of 62.9% and 71% (p = .38) and severe disease-free 30-day survival of 50.6% and 47.5% (p = .91). These findings suggest that severity of COVID-19 in KTRs is related to their associated comorbidities and not to chronic immunosuppression.

Anticoagulation Before Hospitalization Is a Potential Protective Factor for COVID-19: Insight From a French Multicenter Cohort Study

Background

Coronavirus disease 2019 (COVID‐19) is a respiratory disease associated with thrombotic outcomes with coagulation and endothelial disorders. Based on that, several anticoagulation guidelines have been proposed. We aimed to determine whether anticoagulation therapy modifies the risk of developing severe COVID‐19.

Methods and Results

Patients with COVID‐19 initially admitted in medical wards of 24 French hospitals were included prospectively from February 26 to April 20, 2020. We used a Poisson regression model, Cox proportional hazard model, and matched propensity score to assess the effect of anticoagulation on outcomes (intensive care unit admission or in‐hospital mortality). The study enrolled 2878 patients with COVID‐19, among whom 382 (13.2%) were treated with oral anticoagulation therapy before hospitalization. After adjustment, anticoagulation therapy before hospitalization was associated with a better prognosis with an adjusted hazard ratio of 0.70 (95% CI, 0.55–0.88). Analyses performed using propensity score matching confirmed that anticoagulation therapy before hospitalization was associated with a better prognosis, with an adjusted hazard ratio of 0.43 (95% CI, 0.29–0.63) for intensive care unit admission and adjusted hazard ratio of 0.76 (95% CI, 0.61–0.98) for composite criteria intensive care unit admission or death. In contrast, therapeutic or prophylactic low‐ or high‐dose anticoagulation started during hospitalization were not associated with any of the outcomes.

Conclusions

Anticoagulation therapy used before hospitalization in medical wards was associated with a better prognosis in contrast with anticoagulation initiated during hospitalization. Anticoagulation therapy introduced in early disease could better prevent COVID‐19–associated coagulopathy and endotheliopathy, and lead to a better prognosis.

Cardiovascular Comorbidities and Covid-19 in Women

Background

While women account for 40-50 % of patients hospitalized for coronavirus disease 2019 (Covid-19), no specific data have been reported in this population.

Purpose

Assess the burden of cardiovascular comorbidities on outcomes in women hospitalized for Covid-19.

Methods

We conducted a retrospective observational multicenter study from February 26 to April 20, 2020 in 24 French hospitals including all adults admitted for Covid-19. Primary composite outcome included transfer to intensive care unit (ICU) or in-hospital death.

Results

Among 2878 patients hospitalized for Covid-19, 1212 (42.1 %) were women. Women were significantly older (68.3 ± 18.0 vs. 65.4 ± 16.0 years, P < 0.001) but had less prevalent cardiovascular comorbidities than men. Among women, 276 (22.8 %) experienced the primary outcome, including 161 (13.3 %) transfer to ICU and 115 (9.5 %) deaths without transfer to ICU. The survival free from death or transfer to ICU was higher in women (HR 0.63, 95 %CI 0.53-0.73, P < 0.001), whereas the observed difference in in-hospital deaths did not reach statistical significance (P = 0.18). The proportion of women that experienced the primary outcome were 37.8 % in women with heart failure (n = 112), 30.9 % in women with coronary artery disease (n = 81), 29.1 % in women with diabetes (n = 254), 26.1 % in women with dyslipidemia (n = 315), and 26.0 % in women with hypertension (n = 632). Age (HR 1.05, 5 years increments, 95 %CI 1.01-1.10), body mass index (HR 1.06, 2 units increments, 95 %CI 1.02-1.10), chronic kidney disease (HR 1.57, 95 %CI 1.11-2.22), and heart failure (HR 1.52, 95 %CI 1.04-2.22) were independently associated with the primary outcome (Fig. 1).

Conclusions

Women hospitalized for Covid-19 were older and had less prevalent cardiovascular comorbidities than men. While female sex was associated with a lower risk of transfer to ICU or in-hospital death, Covid-19 remains associated with considerable morbi-mortality in women, especially in those with cardiovascular diseases.

Myocardial infarction rates overview during COVID-19 pandemic In France: Results of the MODIF registry

Background

The emergence of Coronavirus disease 2019 (COVID-19) has evolved into a global pandemic. Systems of care have been reorganized worldwide in an effort to preserve hospital bed capacity. In France, from March 17 to May 11 2020, government imposed a complete lockdown on the whole population. Only urgent cardiac procedures have been ensured such as ST-elevation myocardial infarction (STEMI) revascularization. Some previously published studies suggest a reduction of admission for STEMI in many countries. Nevertheless, strong evidences and data across different French regions that have been affected variously by the outbreak are still lacking.

Purpose

We aimed to describe the incidence rates and characteristics of patients presenting with STEMI in order to evaluate the impact of the COVID-19 outbreak on STEMI care in France covering the lockdown period compared to same period one year ago.

Methods

We performed a retrospective multicenter registry across 60 French interventional cardiology centers including all consecutive STEMI patients referred for urgent revascularization in the heart catheterization laboratory between two periods: March 1^st to May 31th 2020 compared with March 1^st to May 31th 2019. Comprehensive data, including clinical, biological, COVID status and angiographic variables including time taken for care were recorded at admission. The primary outcome was a composite of invasive mechanical ventilation support or in-hospital death. The secondary outcome was the occurrence of myocardial infarction related complications during hospitalization. Enrollement is not complete at the time of the abstract submission.

Conclusion

This data collection between two periods with and without COVID19 will gave insights for a complete descriptive cartography of STEMI patients among different French regions which have been variously impacted by the outbreak.

Pulmonary Embolism in Covid-19 patients: A French Multicentre Cohort Study

Background

While pulmonary embolism (PE) appears to be a major issue in Covid-19, data remain sparse.

Purpose

We aimed to describe the risk factors and baseline characteristics of patients with PE in a large cohort of Covid-19 patients.

Methods

In a retrospective multicentric observational study, we included consecutive hospitalised patients for Covid-19. Patients without computed tomography pulmonary angiography (CTPA)-proven PE diagnosis, those who were directly admitted to an intensive care unit (ICU), and those still hospitalised without PE experience were excluded.

Results

Among 1240 patients (58.1% men, mean age 64 ± 17 years), 103 (8.3%) patients had PE confirmed by CTPA. The ICU transfer requirement and mechanical ventilation requirement were significantly higher in the PE group (P < 0.001 and P < 0.001, respectively). In an univariable analysis, traditional venous thromboembolic risk factors were not associated with PE (P > 0.05), while patients under therapeutic-dose anticoagulation before hospitalisation or prophylaxis-dose anticoagulation introduced during hospitalisation had lower PE occurrence (OR 0.40, 95%CI(0.14-0.91); P = 0.04 and OR 0.11, 95%CI(0.06-0.18); P < 0.001, respectively). In a multivariable analysis, the following variables (also statistically significant in univariable analysis) were associated with PE: male gender (OR 1.03, 95%CI(1.003-1.069); P = 0.04), anticoagulation with prophylaxis-dose (OR 0.83, 95%CI(0.79-0.85), P < 0.001) or therapeutic-dose (OR 0.87, 95%CI(0.82-0.92), P < 0.001), C-reactive protein (OR 1.03, 95%CI(1.01-1.04), P = 0.001) and time from symptom onset to hospitalisation (OR 1.02, 95%CI(1.006-1.038), P = 0.002) (Table 1).

Conclusion

Pulmonary embolism risk factors in Covid-19 context do not include traditional thromboembolic risk factors but rather independent clinical and biological findings at admission, including a major contribution to inflammation.

In an univariable analysis, traditional venous thrombo-embolic risk factors were not associated with PE (P > 0.05), while patients under therapeutic dose anticoagulation before hospitalization or prophylactic dose anticoagulation introduced during hospitalization had lower PE occurrence [odds ratio (OR) 0.40, 95% confidence interval (CI) 0.14–0.91, P = 0.04; and OR 0.11, 95% CI 0.06–0.18, P < 0.001, respectively]. In a multivariable analysis, the following variables, also statistically significant in univariable analysis, were associated with PE: male gender (OR 1.03, 95% CI 1.003–1.069, P = 0.04), anticoagulation with a prophylactic dose (OR 0.83, 95% CI 0.79–0.85, P < 0.001) or a therapeutic dose (OR 0.87, 95% CI 0.82–0.92, P < 0.001), C-reactive protein (OR 1.03, 95% CI 1.01–1.04, P = 0.001), and time from symptom onset to hospitalization (OR 1.02, 95% CI 1.006–1.038, P = 0.002).

Conclusion

PE risk factors in the COVID-19 context do not include traditional thrombo-embolic risk factors but rather independent clinical and biological findings at admission, including a major contribution to inflammation.
