Impact of the COVID-19 pandemic on acute coronary syndromes

Heart disease and stroke statistics 2023 update from the American Heart Association-implications for nephrology

The annual American Heart Association (AHA) and National Institutes of Health statistical report details the most up to date statistics related to heart disease, stroke and cardiovascular risk factors, primarily within the USA. Although not a formal systematic review or meta-analysis, this 600 page report provides the most comprehensive and best summary of cardiovascular statistics for the year in question. Although data are collated from USA data registries, it serves as a critical resource for clinicians, policymakers, administrators and researchers in the northern and southern hemispheres. In this special report, we have chosen to highlight aspects of the document that are relevant to nephrologists, given the overlap of cardiovascular and renal disease. These include (i) key and emerging cardiovascular data signals in the general and chronic kidney disease (CKD) populations, (ii) ethnic and socio-economic disparity, (iii) environmental and behavioural factors that drive high levels of cardiovascular disease and which are key components of the AHA's eight components of the Life Essential cardiovascular health score, and (iv) the impact of COVID-19 both directly and indirectly on heart health. We provide some commentary and critical analysis of both the data and of the production of such data sets suggesting that similar data on CKD could also be published and linked to the AHA and other datasets.

2024 Heart Disease and Stroke Statistics: A Report of US and Global Data From the American Heart Association

BACKGROUND

The American Heart Association (AHA), in conjunction with the National Institutes of Health, annually reports the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, nutrition, sleep, and obesity) and health factors (cholesterol, blood pressure, glucose control, and metabolic syndrome) that contribute to cardiovascular health. The AHA Heart Disease and Stroke Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, brain health, complications of pregnancy, kidney disease, congenital heart disease, rhythm disorders, sudden cardiac arrest, subclinical atherosclerosis, coronary heart disease, cardiomyopathy, heart failure, valvular disease, venous thromboembolism, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs).

METHODS

The AHA, through its Epidemiology and Prevention Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States and globally to provide the most current information available in the annual Statistical Update with review of published literature through the year before writing. The 2024 AHA Statistical Update is the product of a full year's worth of effort in 2023 by dedicated volunteer clinicians and scientists, committed government professionals, and AHA staff members. The AHA strives to further understand and help heal health problems inflicted by structural racism, a public health crisis that can significantly damage physical and mental health and perpetuate disparities in access to health care, education, income, housing, and several other factors vital to healthy lives. This year's edition includes additional global data, as well as data on the monitoring and benefits of cardiovascular health in the population, with an enhanced focus on health equity across several key domains.

RESULTS

Each of the chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics.

CONCLUSIONS

The Statistical Update represents a critical resource for the lay public, policymakers, media professionals, clinicians, health care administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

Changes in diagnostic patterns and resource utilisation in Swiss adult ICUs during the first two COVID-19 waves: an exploratory study

BACKGROUND AND AIM

The coronavirus disease 2019 (COVID-19) outbreak deeply affected intensive care units (ICUs). We aimed to explore the main changes in the distribution and characteristics of Swiss ICU patients during the first two COVID-19 waves and to relate these figures with those of the preceding two years.

METHODS

Using the national ICU registry, we conducted an exploratory study to assess the number of ICU admissions in Switzerland and their changes over time, characteristics of the admissions, the length of stay (LOS) and its trend over time, ICU mortality and changes in therapeutic nursing workload and hospital resources in 2020 and compare them with the average figures in 2018 and 2019.

RESULTS

After analysing 242,935 patient records from all 84 certified Swiss ICUs, we found a significant decrease in admissions (-9.6%, corresponding to -8005 patients) in 2020 compared to 2018/2019, with an increase in the proportion of men admitted (61.3% vs 59.6%; p <0.001). This reduction occurred in all Swiss regions except Ticino. Planned admissions decreased from 25,020 to 22,021 in 2020 and mainly affected the neurological/neurosurgical (-14.9%), gastrointestinal (-13.9%) and cardiovascular (-9.3%) pathologies. Unplanned admissions due to respiratory diagnoses increased by 1971 (+25.2%), and those of patients with acute respiratory distress syndrome (ARDS) requiring isolation reached 9973 (+109.9%). The LOS increased by 20.8% from 2.55 ± 4.92 days (median 1.05) in 2018/2019 to 3.08 ± 5.87 days (median 1.11 days; p <0.001), resulting in an additional 19,753 inpatient days. The nine equivalents of nursing manpower use score (NEMS) of the first nursing shift (21.6 ± 9.0 vs 20.8 ± 9.4; p <0.001), the total NEMS per patient (251.0 ± 526.8 vs 198.9 ± 413.8; p <0.01) and mortality (5.7% vs 4.7%; p <0.001) increased in 2020. The number of ICU beds increased from 979 to 1012 (+3.4%), as did the number of beds equipped with mechanical ventilators (from 773 to 821; +6.2%).

CONCLUSIONS

Based on a comprehensive national data set, our report describes the profound changes triggered by COVID-19 over one year in Swiss ICUs. We observed an overall decrease in admissions and a shift in admission types, with fewer planned hospitalisations, suggesting the loss of approximately 3000 elective interventions. We found a substantial increase in unplanned admissions due to respiratory diagnoses, a doubling of ARDS cases requiring isolation, an increase in ICU LOS associated with substantial nationwide growth in ICU days, an augmented need for life-sustaining therapies and specific therapeutic resources and worse outcomes.

In need of percutaneous coronary intervention in an arctic setting- patients' experience of safety and quality of care: a qualitative study

Patients with coronary heart disease need timely treatment for survival and optimum prognosis. There is limited research exploring patients' experience regarding distance to percutaneous coronary intervention. The aim was to explore patients' experiences of aspects contributing to safety and quality of care regarding health services following percutaneous coronary intervention in Northern Norway. A qualitative explorative design was used, and 15 patients participated in individual semi-structured interviews 9-16 months after treatment. The reflexive thematic analysis revealed two main themes: (1) being part of a safe system and (2) adapting to new everyday life. Feeling safe and experiencing quality care depended on whether the participants were heard within the system upon first contact, whether help was available when needed, the travel time for treatment, sufficient information, the competency of care provided by healthcare professionals, and how follow-up services were organised when adapting to everyday life. To conclude, patients undergoing percutaneous coronary intervention in an arctic context perceived healthcare services as safe when the system delivered continuous care throughout all levels. Consistent optimisation of transport time and distance to treatment, especially for rural patients, and extensively focusing on follow-up services, can contribute to improving safety and quality of care.

The impact of the COVID-19 pandemic on delayed care of cardiovascular diseases in Europe: a systematic review

AIMS

Cardiovascular diseases (CVD) are the leading cause of death worldwide. The coronavirus disease 2019 (COVID-19) pandemic has disrupted healthcare systems, causing delays in essential medical services, and potentially impacting CVD treatment. This study aims to estimate the impact of the pandemic on delayed CVD care in Europe by providing a systematic overview of the available evidence.

METHODS AND RESULTS

PubMed, Embase, and Web of Science were searched until mid-September 2022 for studies focused on the impact of delayed CVD care due to the pandemic in Europe among adult patients. Outcomes were changes in hospital admissions, mortality rates, delays in seeking medical help after symptom onset, delays in treatment initiation, and change in the number of treatment procedures. We included 132 studies, of which all were observational retrospective. Results were presented in five disease groups: ischaemic heart diseases (IHD), cerebrovascular accidents (CVA), cardiac arrests (CA), heart failures (HF), and others, including broader CVD groups. There were significant decreases in hospital admissions for IHD, CVA, HF and urgent and elective cardiac procedures, and significant increases for CA. Mortality rates were higher for IHD and CVA.

CONCLUSION

The pandemic led to reduced acute CVD hospital admissions and increased mortality rates. Delays in seeking medical help were observed, while urgent and elective cardiac procedures decreased. Adequate resource allocation, clear guidelines on how to handle care during health crises, reduced delays, and healthy lifestyle promotion should be implemented. The long-term impact of pandemics on delayed CVD care, and the health-economic impact of COVID-19 should be further evaluated.

Monthly variations in acute coronary syndromes outcomes during the first year of the COVID-19 pandemic

BACKGROUND

Cardiovascular disease, particularly acute coronary syndromes (ACS), is the leading cause of death in the United States. Minor fluctuations in hospital admissions for different conditions, including ACS, can be seen throughout the year. This study focuses on the impact of admission month on outcomes of acute coronary syndromes during the first year of the COVID-19 pandemic.

METHODS

This was a retrospective observational study of patients hospitalized with ACS from the National Inpatient Sample, during the years 2020 (n = 779,895) and 2019 (n = 935,975). We compared the monthly outcomes for every month to the outcomes for the month of January of that same year. The primary outcomes of interest were in-hospital mortality and time from admission to PCI.

RESULTS

Inpatient mortality for patients admitted with STEMI was significantly higher for admissions in the months of April, October and December of 2020 than January of that same year. For patients admitted with NSTEMI or UA, inpatient mortality was higher for admissions in April and December 2020 when compared to admissions in January 2020. Inpatient mortality for patients with STEMI, NSTEMI and UA was not different based on admission month in the year 2019.

CONCLUSION

The month of admission significantly affected outcomes for patients admitted with ACS during the COVID-19 pandemic, with higher inpatient mortality and longer time from admission to PCI for certain months in 2020. Further studies should investigate disparities in monthly ACS outcomes for the year 2021 and onward, now that COVID-19 infections have been steadily declining.

Pre-hospital and Hospital Trauma Care during the Covid-19 Lockdown - Experience in a Metropolitan European Level 1 Trauma Centre

BACKGROUND

Trauma case load is said to have declined during the Covid-19 pandemic, especially during the national lockdowns. Due to the altered frequency and changes in daily life, pre-hospital care (altered personal protective measurements) as well as mechanisms of trauma and initial trauma treatment may have changed. The purpose of this study was to assess differences in pre-hospital as well as initial treatment of trauma victims and trauma mechanisms during a national lockdown compared to the year before.

MATERIAL AND METHODS

Pre-hospital as well as clinical data from all trauma patients admitted to our metropolitan level 1 trauma center resuscitation room during the hard lockdown in Switzerland (March 17 to April 26, 2020) and the same time period in 2019 were analyzed retrospectively.

RESULTS

In total, we assessed 91 patients (51 lockdown cohort, 40 control cohort) with a mean age of 50.7 years. Significantly more trauma was sustained in the household environment during the lockdown (p = 0.015). Pre-hospital treatment remained similar between the two assessed groups. No difference was found in length of stay or mortality. In severely injured patients (ISS > 15), we found significantly fewer motor vehicle accidents (p = 0.018) and fewer horizontal decelerations (p = 0.006), but insignificantly more falls (p = 0.092) in the lockdown cohort. None of the patients in the lockdown cohort had a positive PCR test for Covid-19 on admission.

CONCLUSION

Trauma systems seem not to have changed during hard lockdowns in terms of pre-hospital treatment. Fewer severely injured patients due to motor vehicle accidents and horizontal decelerations, but more household-related injuries were seen in the lockdown cohort than in the control cohort. A qualitative analysis of treatment during the hard lockdown is needed to gain further insights into the effect of the pandemic on trauma care.

Impact of COVID-19 pandemic on emergency medical system and management strategies in patients with acute coronary syndrome

The global coronavirus disease-2019 (COVID-19) pandemic is associated with reduced rate of percutaneous coronary intervention (PCI). However, there were a few data showing how emergency medical system (EMS) and management strategies for acute coronary syndrome (ACS) changed during the pandemic. We sought to clarify changes on characteristics, treatments, and in-hospital mortality of patients with ACS transported via EMS between pre- and post-pandemic. We examined consecutive 656 patients with ACS admitted to Sapporo City ACS Network Hospitals between June 2018 and November 2021. The patients were divided into pre- and post-pandemic groups. The number of ACS hospitalizations declined significantly during the pandemic (proportional reduction 66%, coefficient -0.34, 95% CI -0.50 to -0.18, p < 0.001). The median time from an EMS call to hospital was significantly longer in post-pandemic group than in pre-pandemic group (32 [26-39] vs. 29 [25-36] min, p = 0.008). There were no significant differences in the proportion of patients with ACS receiving PCI, and in-hospital mortality between the groups. The COVID-19 pandemic had a significant impact on EMS and management in patients with ACS. Although a significant decline was observed in ACS hospitalizations, the proportion of patients with ACS receiving emergency PCI remained during the pandemic.

The change in pediatric subject symptoms during the COVID-19 pandemic in China: an increase in cardiac consultation

BACKGROUND

It is reported that the adverse impact of nonpharmaceutical interventions (NPIs) on the mental health of children and adolescents may lead to psychologically related disorders during the coronavirus disease 2019 (COVID-19) period. Subject symptoms such as chest pain, chest tightness, and palpitation may be related to increased stress and anxiety in children and adolescents. The present research aimed to determine the number of pediatric consults and etiology of subject symptoms during the COVID-19 pandemic period and compared it with the same timelines in 2019 and 2021 to discuss the impact of different periods on the organic disease onset of children with subject symptoms, especially in cardiac involvement.

METHODS

Children who visited Qingdao Women and Children's Hospital, Qingdao University between January 23 to April 30, 2019 (pre-COVID-19 period), January 23 to April 30, 2020 (COVID-19 period), and January 23 to April 30, 2021 (post-COVID-19 period) presenting chest pain, chest tightness, and palpitation were recruited. Information to determine gender, age, medical history, department for the initial visit, clinical manifestations, time from the latest onset to the visit, and diagnosis were recorded.

RESULT

A total of 891 patients were enrolled in the present study (514 males; median age: 7.72). One hundred twenty-three patients presented during the pre-COVID-19 period while 130 during the COVID-19 period, nevertheless, the number substantially increased during the post-COVID-19 period (n = 638). Cardiac etiology accounted for 1.68% (n = 15) of the patient population, including arrhythmias (n = 10, 1.12%), myocarditis (n = 4, 0.44%), and atrial septal defect (n = 1, 0.11%). There was no significant difference among groups in the distribution of organic etiology. The median time from the latest onset to the visit during the pre-COVID-19 period was 7 days compared to 10 days during the COVID-19 period and 3 days during the post-COVID period.

CONCLUSION

During the post-COVID-19 period, the median time from the latest onset to the visit was significantly shorter than that in the pre-COVID-19 period or COVID-19 period. The pediatric consult of children with subject symptoms presented increased substantially during the post-COVID-19 period, while there was no significant difference in the number of patients involving the cardiac disease. Clinicians ought to be more careful to screen heart diseases to prevent missed diagnosis and misdiagnosis during special periods.

Impact of SARS-CoV-2 Outbreak on Emergency Department Presentation and Prognosis of Patients with Acute Myocardial Infarction: A Systematic Review and Updated Meta-Analysis

We performed an updated meta-analysis to robustly quantify admission trends of patients with ST-segment elevation MI (STEMI) and non-ST-segment elevation MI (NSTEMI) during the first wave of the pandemic and to characterize on a large basis the risk profile and early prognosis. Studies having the same observation period for the comparison between SARS-CoV-2 outbreak in 2020 versus control period in 2019 were included. Primary endpoints were the relative variation of hospital admissions, the difference of in-hospital mortality for STEMI and NSTEMI. Secondary were: mortality according to countries, income levels and data quality; cardiogenic shock, mechanical complications, door-to-balloon time, time from symptom onset to first medical contact, left ventricular ejection fraction (LVEF) and troponin. In total, 61 observational studies with 125,346 patients were included. Compared with 2019, during the pandemic for STEMI were observed: a 24% reduction of hospitalizations with an impact on early survival (OR = 1.33 in-hospital mortality); the time from symptom onset to first medical contact was 91.31 min longer, whereas door-to-balloon time was increased (+5.44 min); after STEMI, the rate of cardiogenic shock was 33% higher; LVEF at discharge was decreased (−3.46); elevated high-sensitivity troponin levels (1.52) on admission. For NSTEMI, in the COVID-19 period, we observed a 31% reduction of hospitalizations and higher in-hospital deaths (OR = 1.34). The highest mortality rates among countries were: Italy OR = 3.71 (high income), Serbia OR = 2.15 (upper middle) and Pakistan OR = 1.69 (lower middle). Later hospital presentation was associated with larger infarctions, as well as with increased cardiogenic shock and in-hospital mortality.

The Impact of the COVID-19 Pandemic on Hospital Services for Patients with Cardiac Diseases: A Scoping Review

This study aims to assess the impact of the COVID-19 pandemic on hospital cardiac care, as assessed by performance indicators. Scoping review methodology: performance indicators were extracted to inform on changes in care during January–June 2020. Database searches yielded 6277 articles, of which 838 met the inclusion criteria. After full-text screening, 94 articles were included and 1637 indicators were retrieved. Most of the indicators that provided information on changes in the number of admissions (n = 118, 88%) signaled a decrease in admissions; 88% (n = 15) of the indicators showed patients’ delayed presentation and 40% (n = 54) showed patients in a worse clinical condition. A reduction in diagnostic and treatment procedures was signaled by 95% (n = 18) and 81% (n = 64) of the indicators, respectively. Length of stay decreased in 58% (n = 21) of the indicators, acute coronary syndromes treatment times increased in 61% (n = 65) of the indicators, and outpatient activity decreased in 94% (n = 17) of the indicators related to outpatient care. Telehealth utilization increased in 100% (n = 6). Outcomes worsened in 40% (n = 35) of the indicators, and mortality rates increased in 52% (n = 31). All phases of the pathway were affected. This information could support the planning of care during the ongoing pandemic and in future events.

Impact of the COVID-19 Pandemic on Patients With Acute Coronary Syndrome: A Tertiary Center Experience With Primary Percutaneous Intervention and Early Invasive Strategy

Objective: This study aimed to determine the impact of the coronavirus disease 2019 (COVID-19) pandemic on patients with acute coronary syndrome (ACS).

Methods: This retrospective longitudinal cohort study analysed ACS patients admitted in a large tertiary center in 2019 (pre-pandemic) and 2020 (pandemic). The primary endpoint was mortality from myocardial infarction; secondary endpoints were death from any causes, including COVID-related complications, stroke, and coronary artery bypass graft surgery.

Results: There were 489 ACS patients admitted in 2020, and 614 in 2019, representing a 21% reduction (p=0.001). Male patients comprised 73% of the patients. Only eight were polymerase chain reaction (PCR)-confirmed positive COVID-19 patients. The mean time to presentation from the time of onset of symptoms in acute ST-elevation myocardial infarction cases was 48±16 in 2020 (vs. 4±3 h in 2019); this significant delay was observed in more than 50% of patients (p=0.0001). Mortality due to ACS in 2020 doubled, with eight patients confirmed dead during or within 30 days of admission, with none of the deaths related to COVID-19. The incidence of stroke (p=0.01) and coronary artery (p=0.0001) bypass was also high in 2020.

Conclusion: We found a statistically significant increase in the mortality related to myocardial infarction. Despite timely interventions, patients presented late and were worse than in the non-pandemic period.

Telehealth at scale can improve chronic disease management in the community during a pandemic: An experience at the time of COVID-19

Background

During the COVID-19 pandemic, telehealth became a vital resource to contain the virus’s spread and ensure continuity of care of patients with a chronic condition, notably arterial hypertension and heart disease. This paper reports the experience based on a telehealth platform used at scale to manage chronic disease patients in the Italian community.

Methods and findings

Patients’ health status was remotely monitored through ambulatory blood pressure monitoring (ABPM), resting or ambulatory electrocardiogram (ECG), spirometry, sleep oximetry, and cardiorespiratory polysomnography performed in community pharmacies or general practitioners’ offices. Patients also monitored their blood pressure (BP), heart rate (HR), blood oxygen saturation (SpO₂), body temperature, body weight, waist circumference, blood glucose, and lipids at home through a dedicated smartphone app. All data conveyed to the web-based telehealth platform were used to manage critical patients by doctors promptly. Data were analyzed and compared across three consecutive periods of 2 months each: i) before the national lockdown, ii) during the lockdown (from March 9 to May 17, 2020), and iii) after the end of the containment measures. Overall, 13,613 patients visited community pharmacies or doctors’ offices. The number of overall tests dropped during and rose after the lockdown. The overall proportion of abnormal tests was larger during the outbreak. A significant increase in the prevalence of abnormal ECGs due to myocardial ischemia, contrasted by a significantly improved BP control, was observed. The number of home users and readings exchanged increased during the pandemic. In 226 patients, a significant increase in the proportion of SpO₂ readings and a significant reduction in the entries for all other parameters, except BP, was observed. The proportion of abnormal SpO₂ and BP values was significantly lower during the lockdown. Following the lockdown, the proportion of abnormal body weight or waist circumference values increased.

Conclusions

Our study results support the usefulness of a telehealth solution to detect deterioration of the health status during the COVID-19 pandemic.

Trial registration

The study is registered with ClinicalTrials.gov at number NCT03781401.

Impact of COVID-19 Pandemic on STEMI Networks in Central Romania

The COVID-19 pandemic has had a major impact on cardiovascular emergencies. The aim of this study was to investigate the impact of the COVID-19 pandemic on a regional network for management of ST-segment elevation acute myocardial infarction (STEMI).

METHODS

We report a single center's experience of patients hospitalized for ACS in a high-volume hub of a STEMI network during the lockdown (in the first pandemic trimester), compared with the same time interval of the previous year and including all consecutive patients referred for an AMI during the second trimester of 2020 (from April to June) or during the same time interval of the previous year, 2019.

RESULTS

The absolute number of hospital admissions for AMI decreased by 22.3%, while the non-AMI hospitalizations decreased by 77.14% in Q2-2020 compared to Q2-2019 (210 vs. 48, p < 0.0001). As a consequence, the percentage of AMI cases from the total number of hospital admission increased from 38% to 68% (p < 0.0001), AMI becoming the dominant pathology. In the STEMI group there was a significant reduction of 55% in the absolute number of late STEMI presentations. Functionality of the STEMI network at the hub level did not present a significant alteration with only a minor increase in the door-to-balloon time, from 34 min to 41 min. However, at the level of the network we recorded a lower number of critical cases transferred to the interventional center, with a dramatic reduction of 56.1% in the number of critical STEMI cases arriving in the acute cardiac care unit (17.0% vs. 7.3%, p-0.04 for KILLIP class III, and 21.17% vs. 11.11%, p = 0.08 for resuscitated out of hospital cardiac arrest).

CONCLUSIONS

The COVID-19 outbreak did not have a major impact on the interventional center's functionality, but it limited the capacity of the regional STEMI network to bring the critical patient with complicated STEMI to the cathlab in time during the first months of the lockdown. Even a very well-functioning STEMI network like the one in Central Romania had difficulties bringing the most critical STEMI cases to the cathlab in time.

Impact on polytrauma patient prehospital care during the first wave of the COVID-19 pandemic: a cross-sectional study

Background

The extraordinary situation caused by the onset of COVID-19 has meant that at prehospital level, the number of treatments, profile and time taken to respond for treating time-dependent pathologies has been greatly affected. However, it is not known whether the prehospital profile of polytrauma patients (PTP) has been affected.

Objective

To determine differences in the epidemiological characteristics and the clinical variables of prehospital polytrauma patients during the first wave of the COVID-19 pandemic in Catalonia.

Methodology

Analytical cross-sectional study. The number of prehospital activations and the clinical and epidemiological characteristics of polytrauma patients attended by the Emergency Medical System (EMS) of Catalonia, were compared for the period between 15 February and 15 May 2020 and the same period in the previous year. Priorities 0 and 1 are assigned to the most severely injured patients. An analysis was conducted using logistic regression and nonparametric tests.

Results

3023 patients were included. During the 2019 study period, 2045 (67.6%) patients were treated; however, during the pandemic period, 978 (32.4%) patients were treated, representing a 52% decrease (p = 0.002). The percentage of patients presenting priority 1 was higher during the pandemic period [240 (11.7%) vs 146 (14.9%), p = 0.032]. The percentage of priority 0 and 1 patients attended by a basic life support unit increased [201 (9.8%) vs 133 (13.6%), p = 0.006]. The number of traffic accidents decreased from 1211 (59.2%) to 522 (53.4%) and pedestrian-vehicle collisions fell from 249 (12.2%) to 92 (9.4%). Regarding weapon-related injuries and burns, there was an increase in the number of cases [43 (2.1%) vs 41 (4.2%), and 15 (0.7%) vs 22 (2.2%), p = 0.002 and p < 0.001, respectively]. Hospital mortality remained unchanged (3.9%).

Conclusions

During the first wave of the pandemic, the number of polytrauma patients decreased and there was a change in the profile of severity and type of accident.

[Impact of the COVID-19 pandemic on ST - elevation myocardial infarction management in a reference center of northern Peru]

Objective

To evaluate the impact of the COVID-19 pandemic on the ST-Elevation myocardial infarction (STEMI) management in a reference center of northern Peru.

Methods

Observational, analytical, retrospective cohort-type study, derivated from the Acute Coronary Syndrome registry of the Almanzor Aguinaga Asenjo National Hospital. The characteristics of the patients with STEMI and their 30-day outcomes were compared in 02 cohorts according to the time of medical care: prior to the pandemic or during the pandemic.

Results

During the COVID-19 pandemic, hospitalizations for STEMI decreased by 53%, there was a greater use of fibrinolysis to the detriment of primary angioplasty, with increases in the time of first medical contact (100 vs. 240 minutes, p = 0.006) and ischemic time to percutaneous coronary intervention (900 vs. 2880 minutes, p <0.001). This generated a higher frequency of post-infarction heart failure (21.1% vs. 46.7%, p = 0.002) and a lower left ventricular ejection fraction at discharge (49.2 +/- 8.6 vs 44.8 +/- 9.3, p = 0.009), without an increase in in-hospital cardiovascular mortality.

Conclusions

The COVID-19 has had a negative impact on the treatment of patients with STEMI. We found less hospitalizations, prolonged reperfusion times, and higher frequency of post-infarction heart failure and lower left ventricular ejection fraction at discharge.

Impact on percutaneous coronary intervention for acute coronary syndromes during the COVID-19 outbreak in a non-overwhelmed European healthcare system: COVID-19 ACS-PCI experience in Ireland

AIMS

To evaluate temporal trends of acute coronary syndromes (ACS) treated via percutaneous coronary intervention (PCI) throughout the COVID-19 outbreak in a European healthcare system affected but not overwhelmed by COVID-19-related pathology.

METHODS AND RESULTS

We performed a retrospective multicentre analysis of the rates of PCI for the treatment of ACS within the period 2 months pre and post the first confirmed COVID-19 case in Ireland, as well as comparing PCI for ST-elevation myocardial infarction (STEMI) with the corresponding period in 2019. During the 2020 COVID-19 period (29 February-30 April 2020), there was a 24% decline in PCI for overall ACS (incidence rate ratio (IRR) 0.76; 95% CI 0.65 to 0.88; p<0.001), including a 29% reduction in PCI for non-ST-elevation ACS (IRR 0.71; 95% CI 0.57 to 0.88; p=0.002) and an 18% reduction in PCI for STEMI (IRR 0.82; 95% CI 0.67 to 1.01; p=0.061), as compared with the 2020 pre-COVID-19 period (1 January-28 February 2020). A 22% (IRR 0.78; 95% CI 0.65 to 0.93; p=0.005) reduction of PCI for STEMI was seen as compared with the 2019 reference period.

CONCLUSION

This study demonstrates a significant reduction in PCI procedures for the treatment of ACS since the COVID-19 outbreak in Ireland. The reasons for this decline are still unclear but patients need to be encouraged to seek medical attention when cardiac symptoms appear, in order to avoid incremental cardiac morbidity and mortality due to a reduction in coronary revascularisation for the treatment of ACS.
