          Background and Purpose:

          Since the onset of the coronavirus 2019 (COVID-19) pandemic, doctors and public authorities have demonstrated concern about the reduction in quality of care for other health conditions due to social restrictions and lack of resources. Using a population-based stroke registry, we investigated the impact of the onset of the COVID-19 pandemic in stroke admissions in Joinville, Brazil.

          Methods:

          Patients admitted after the onset of COVID-19 restrictions in the city (defined as March 17, 2020) were compared with those admitted in 2019. We analyzed differences between stroke incidence, types, severity, reperfusion therapies, and time from stroke onset to admission. Statistical tests were also performed to compare the 30 days before and after COVID-19 to the same period in 2019.

          Results:

          We observed a decrease in total stroke admissions from an average of 12.9/100 000 per month in 2019 to 8.3 after COVID-19 ( P=0.0029). When compared with the same period in 2019, there was a 36.4% reduction in stroke admissions. There was no difference in admissions for severe stroke (National Institutes of Health Stroke Scale score >8), intraparenchymal hemorrhage, and subarachnoid hemorrhage.

          Conclusions:

          The onset of COVID-19 was correlated with a reduction in admissions for transient, mild, and moderate strokes. Given the need to prevent the worsening of symptoms and the occurrence of medical complications in these groups, a reorganization of the stroke-care networks is necessary to reduce collateral damage caused by COVID-19.

          Neurologic Manifestations of Hospitalized Patients With Coronavirus Disease 2019 in Wuhan, China

          The outbreak of coronavirus disease 2019 (COVID-19) in Wuhan, China, is serious and has the potential to become an epidemic worldwide. Several studies have described typical clinical manifestations including fever, cough, diarrhea, and fatigue. However, to our knowledge, it has not been reported that patients with COVID-19 had any neurologic manifestations.

            Global Burden of Stroke.

            On the basis of the GBD (Global Burden of Disease) 2013 Study, this article provides an overview of the global, regional, and country-specific burden of stroke by sex and age groups, including trends in stroke burden from 1990 to 2013, and outlines recommended measures to reduce stroke burden. It shows that although stroke incidence, prevalence, mortality, and disability-adjusted life-years rates tend to decline from 1990 to 2013, the overall stroke burden in terms of absolute number of people affected by, or who remained disabled from, stroke has increased across the globe in both men and women of all ages. This provides a strong argument that "business as usual" for primary stroke prevention is not sufficiently effective. Although prevention of stroke is a complex medical and political issue, there is strong evidence that substantial prevention of stroke is feasible in practice. The need to scale-up the primary prevention actions is urgent.

              Decline of acute coronary syndrome admissions in Austria since the outbreak of COVID-19: the pandemic response causes cardiac collateral damage

              We conducted a nationwide retrospective survey on the impact of COVID-19 on the diagnosis and treatment of acute cornary syndrome (ACS) from 2 to 29 March in Austria. Of the 19 public primary percutaneous coronary (PCI) centres contacted, 17 (90%) provided the number of admitted patients. During the study period, we observed a significant decline in the number of patients admitted to hospital due to ACS (Figure 1 ). Comparing the first and last calendar week, there was a relative reduction of 39.4% in admissions for ACS. In detail, from calendar week 10 to calendar week 13, the number of ST-segment elevation myocardial infarction (STEMI) patients admitted to all hospitals was 94, 101, 89, and 70, respectively. The number of non-STEMI patients declined even more markedly from 132 to 110, to 62, and to 67. Figure 1 Decline of acute coronary syndrome admissions in Austria since the outbreak of COVID-19. The absolute numbers of all ACS (blue bars), STEMI (orange bars), and NSTEMI (grey bars) admissions in Austria from calendar week 10 to calendar week 13 are shown. Abbreviations: STEMI, ST-segment elevation myocardial infarction; NSTEMI, non-ST-segment elevation myocardial infarction. The main finding of our retrospective observational study is an unexpected major decline in hospital admissions and thus treatment for all subtypes of ACS with the beginning of the COVID-19 outbreak in Austria and subsequent large-scale public health measures such as social distancing, self-isolation, and quarantining. Several factors might explain this important observation. The rigorous public health measures, which are undoubtedly critical for controlling the COVID-19 pandemic, may unintentionally affect established integrated care systems. Amongst others, patient-related factors could mean that infarct-related symptoms such as chest discomfort and dyspnoea could be misinterpreted as being related to an acute respiratory infection. Moreover, the strict instructions to stay at home as well as the fear of infection in a medical facility may have further prevented patients with an ACS from going to a hospital. Irrespective of the causes, the lower rate of admitted and therefore treated patients with ACS is worrisome and we are concerned that this might be accompanied by a substantial increase in early and late infarct-related morbidity and mortality. Our study does not provide data on mortality; however, considering the annual incidence of ACS in Austria (200/100 000/year = 17 600/year in 8.8 million habitants) 1 and taking into consideration sudden cardiac deaths and silent infarctions (one-third), there will remain ∼1000 ACS cases a month. The difference between the assumed number of ACS patients and the observed number in our study, i.e. 725 ACS patients in calendar weeks 10–13 is 275. According to these assumptions, 275 patients were not treated in March 2020. Based on data showing that the cardiovascular mortality of untreated ACS patients might be as high as 40% (as it was in the 1950s), 2 we can theoretically estimate 110 ACS deaths during this time frame. The number of deaths associated with this unintentional undersupply of guideline-directed ACS management is very alarming, particularly when considering that the official number of COVID-related deaths in Austria was 86 on 29 March. In conclusion, it seems likely that the COVID-19 outbreak is associated with a significantly lower rate of hospital admissions and thus, albeit unintended, treatment of ACS patients, which is most likely explained by several patient- and system-related factors. Every effort should be undertaken by the cardiology community to minimize the possible cardiac collateral damage caused by COVID-19.
