Symptoms-to-emergency-call timing delay in acute coronary syndrome before and during COVID-19: independent predictors and their impact on mortality.

BACKGROUND: The COVID-19 pandemic severely impacted global health. The aim of this study was to compare predictors of symptoms-to-emergency-call timing delay in Acute Coronary Syndrome (ACS) and their impact on mortality before and during the COVID-19 outbreak. METHODS: We collected sociodemographic, clinical data, procedural features, pre-admission and intra-hospital outcomes of consecutive patients admitted for ACS in seventeen Italian centers from March to April 2018, 2019, and 2020. RESULTS: In 2020, a 32.92% reduction in ACS admissions was observed compared to 2018 and 2019. Unstable angina, typical and atypical symptoms, and intermittent angina were identified as significant predictors of symptoms-to-emergency-call timing delay before and during the COVID-19 pandemic (p<0.005 for all the items). Differently from 2018-2019, during the pandemic, hypertension and dyspnea (p=0.002 versus [vs] p=0.490 and p=0.001 vs p=0.761 for 2018-2019 and 2020, respectively) did not result as predictors of delay in symptoms-to-emergency-call timing. Among these predictors, only the atypical symptoms (HR 3.36; 95% CI 1.172 - 9.667, p=0.024) in 2020 and the dyspnea (HR 2.64; 95% CI 1.345 - 5.190, p=0.005) in 2018-2019 resulted significantly associated with higher mortality. Finally, the family attendance at the onset of the symptoms resulted in a reduction in symptoms-to-emergency-call timing (in 2020 p<0.001; CI -1710.73; -493.19) and in a trend of reduced mortality (HR 0.31; 95% CI 0.089 - 1.079, p=0.066) in 2020. CONCLUSIONS: During the COVID-19 outbreak, atypical symptoms and family attendance at ACS onset were identified, respectively, as adverse and favorable predictors of symptoms-to-emergencycall timing delay and mortality.

Incidence of acute myocarditis and pericarditis during the coronavirus disease 2019 pandemic: comparison with the prepandemic period.

BACKGROUND: Myocarditis and pericarditis have been proposed to account for a proportion of cardiac injury during SARS-CoV-2 infection. The impact of COVID-19 the pandemic on the incidence of this acute inflammatory cardiac disease was not systematically evaluated. AIM: To examine the incidence and prevalence of inflammatory heart disorders prior to and during the COVID-19 pandemic. METHODS: We compared the incidence and prevalence of acute inflammatory heart diseases (myocarditis, pericarditis) in the provinces of Pisa, Lucca and Livorno in two time intervals: prior to (PRECOVID, from 1 June 2018 to 31 May 2019) and during the COVID-19 pandemic (COVID, from 1 June 2020 to May 2021). RESULTS: Overall 259 cases of inflammatory heart disease (myocarditis and/or pericarditis) occurred in the areas of interest. The annual incidence was of 11.3 cases per 100 000 inhabitants. Particularly, 138 cases occurred in the pre-COVID, and 121 in the COVID period. The annual incidence of inflammatory heart disease was not significantly different (12.1/100 000 in PRECOVID vs 10.3/100 000 in COVID, P = 0.22). The annual incidence of myocarditis was significantly higher in PRECOVID than in COVID, respectively 8.1/100 000/year vs. 5.9/100 000/year (P = 0.047) consisting of a net reduction of 27% of cases. Particularly the incidence of myocarditis was significantly lower in COVID than in PRECOVID in the class of age 18-24 years. Despite this, myocarditis of the COVID period had more wall motion abnormalities and greater LGE extent. The annual incidence of pericarditis was, instead, not significantly different (4.03/100 000 vs, 4.47/100 000, P = 0.61). CONCLUSION: Despite a possible etiologic role of SARS-CoV-2 and an expectable increased incidence of myocarditis and pericarditis, data of this preliminary study, with a geographically limited sample size, suggest a decrease in acute myocarditis and a stable incidence of pericarditis and of myopericarditis/perimyocarditis.

The Incidence and Impact of In-Hospital Bleeding in Patients with Acute Coronary Syndrome during the COVID-19 Pandemic.

BACKGROUND: The COVID-19 pandemic increased the complexity of the clinical management and pharmacological treatment of patients presenting with an Acute Coronary Syndrome (ACS). AIM: to explore the incidence and prognostic impact of in-hospital bleeding in patients presenting with ACS before and during the COVID-19 pandemic. METHODS: We evaluated in-hospital Thrombolysis In Myocardial Infarction (TIMI) major and minor bleeding among 2851 patients with ACS from 17 Italian centers during the first wave of the COVID-19 pandemic (i.e., March-April 2020) and in the same period in the previous two years. RESULTS: The incidence of in-hospital TIMI major and minor bleeding was similar before and during the COVID-19 pandemic. TIMI major or minor bleeding was associated with a significant threefold increase in all-cause mortality, with a similar prognostic impact before and during the COVID-19 pandemic. CONCLUSIONS: the incidence and clinical impact of in-hospital bleeding in ACS patients was similar before and during the COVID-19 pandemic. We confirmed a significant and sizable negative prognostic impact of in-hospital bleeding in ACS patients.

Impact of COVID-19 pandemic on in-hospital outcomes for patients with acute coronary syndrome: a propensity-weighted, multicentre study

Aims Coronavirus disease 19 (COVID-19) pandemic has dramatically changed the management and the prognosis of patients experiencing acute coronary syndrome (ACS). Several scientific societies have highlighted the need for dedicated paths to deliver better and faster care to improve outcomes. Nevertheless, data depicting the impact of COVID-19 pandemic on ACS in Italy are still poor. To perform a propensity weighted analysis on a multicentre Italian registry involving patients with ACS managed before vs. during COVID-19 pandemic, taking into account baseline patients characteristics, clinical presentation, procedural aspects, and in-hospital outcomes (death, bleeding, stent thrombosis, myocardial infarction, stroke/transient ischaemic attack, mechanical complication, and arrhythmic complication). Methods and results We included all consecutive patients who have suffered from ACS during two periods before (March/April 2018, March/April 2019) vs. the period of COVID-19 pandemic (March/April 2020). A generalized boosted non-parsimonious regression was used to estimate the propensity scores of having an ACS in 2020 (year of COVID-19) vs. 2018/2019 using an average treatment effect and balancing for all baseline confounders. We included 2851 patients admitted to hospital with ACS in 17 Italian centres: 1079 (37.8%) during 2018, 1056 (37.0%) in 2019, and 716 (25.1%) during the first COVID-19 wave of 2020. Seventy (2.5%) patients had a positive swab for SARS-CoV-2 at admission. During 2020 there were higher time-to-emergency-call (P = 0.028) and less diagnosis of unstable angina (P = 0.029) and MINOCA (P = 0.004);none of the admission symptoms differ significantly across the years (P > 0.05) except for fever that was more prevalent in 2020 (P < 0.001). Patients suffering from ACS had lower admission EF (P = 0.006). After PS weighting, multivariate Cox regression analysis showed age (P < 0.001), night admission (P = 0.017), cardiocirculatory arrest before cath-lab (P = 0.041), worst Killip class (P = 0.039), admission EF (P = 0.026), and need for left-ventricle mechanical support (P = 0.011) as independent predictors of in-hospital death. After propensity weighted analysis none of the in-hospital outcomes differed significantly across the years of investigation (all P > 0.05). Conclusions During COVID-19 pandemic in Italy the characteristics and management of ACS was slightly different than the past. However, the rates of ‘hard’, in-hospital outcomes (e.g. deaths) are almost similar to the past, suggesting appropriate care and well-organized emergency-paths for ACS.

Incidence and prevalence of acute myocarditis and pericarditis prior to and during COVID-19 pandemic

Aims Myocarditis and pericarditis have been proposed to account for a proportion of cardiac injury during SARS-CoV-2 infection. During the COVID-19 pandemic, it is reasonable to expect an increasing trend in incidence of this acute inflammatory cardiac diseases. To examine the incidence and prevalence of inflammatory heart disorders prior to and during the COVID-19 pandemic. Methods and results This is a retrospective cohort study examining the incidence and prevalence of acute inflammatory heart diseases (myocarditis, pericarditis) in provinces of Pisa, Lucca and Livorno (total population of 11421285 inhabitants) in two time-intervals: (i) prior to (PRECOVID, from 1 June 2018 to 31 May 2019) and (ii) during the COVID-19 pandemic (COVID, from 1 June 2020 to May 2021). Overall 259 cases of inflammatory heart disease (myocarditis and/or pericarditis) occurred in the areas of interest. The annual incidence was of 11.3 cases per 100 000 inhabitants. Particularly, 138 cases occurred in the PRECOVID, and 121 in the COVID period. The annual incidence of inflammatory heart disease was not significantly different (12.1/100 000 in PRECOVID vs. 10.3/100 000 in COVID;P = 0.22). The annual incidence of acute myocarditis was significantly higher in PRECOVID than in the COVID: respectively, 8.1/100 000/year vs. 5.9/100 000 year (P = 0.047), consisting in a net reduction of 27% of cases. Particularly the incidence of myocarditis was significantly lower in COVID than in PRECOVID in the class of age 18–24 (P = 0.048) (Figure). The annual incidence of pericarditis was not significantly different (4.03/100 000 vs. 4.47/100 000;P = 0.61). Conclusions Despite a possible etiologic role of SARS-CoV-2 and an expectable increased incidence of myocarditis and pericarditis, data suggest a decrease of acute myocarditis and a stable incidence pericarditis and both diseases.
