RESUMO

The outbreak of coronavirus disease 2019 (COVID-19) has rapidly spread worldwide. This study sought to share our experiences with in-hospital management and outcomes of acute myocardial infarction (AMI) during the COVID-19 pandemic. We retrospectively analyzed consecutive AMI patients, including those with ST-elevation myocardial infarction (STEMI) and non-STEMI (NSTEMI), from February 1, 2020, to April 15, 2020 (during the COVID-19 pandemic), and from January 1, 2019, to December 31, 2019 (before the COVID-19 pandemic), respectively. Fifty-three AMI patients (31 STEMI, 22 NSTEMI) during the COVID-19 pandemic were matched to 53 AMI patients before the pandemic. Baseline characteristics were comparable between the matched patients. STEMI patients during the COVID-19 pandemic had a longer delay time, less primary or remedial PCI and more emergency thrombolysis than those before the pandemic. Less coronary angiography and stenting were performed in AMI patients during the COVID-19 pandemic than before the pandemic. There were no statistically significant differences in the clinical outcomes between the matched patients. However, STEMI patients during the COVID-19 pandemic had a 4-fold (12.9% vs. 3.2%) increase in all-cause mortality rate compared with those before the pandemic. AMI combined with COVID-19 infection was associated with higher rates of mortality than AMI alone. This study demonstrates that the COVID-19 pandemic results in significant reperfusion delays in STEMI patients and has a marked impact on the treatment options selection in AMI patients. The mortality rate of STEMI patients exhibits an increasing trend during the pandemic of COVID-19.

RESUMO

BACKGROUND: The fear of contagion during the coronavirus disease-2019 (COVID-19) pandemic may have potentially refrained patients with ST-segment elevation myocardial infarction (STEMI) from accessing the emergency system, with subsequent impact on mortality. OBJECTIVES: The ISACS-STEMI COVID-19 registry aims to estimate the true impact of the COVID-19 pandemic on the treatment and outcome of patients with STEMI treated by primary percutaneous coronary intervention (PPCI), with identification of "at-risk" patient cohorts for failure to present or delays to treatment. METHODS: This retrospective registry was performed in European high-volume PPCI centers and assessed patients with STEMI treated with PPPCI in March/April 2019 and 2020. Main outcomes are the incidences of PPCI, delayed treatment, and in-hospital mortality. RESULTS: A total of 6,609 patients underwent PPCI in 77 centers, located in 18 countries. In 2020, during the pandemic, there was a significant reduction in PPCI as compared with 2019 (incidence rate ratio: 0.811; 95% confidence interval: 0.78 to 0.84; p < 0.0001). The heterogeneity among centers was not related to the incidence of death due to COVID-19. A significant interaction was observed for patients with arterial hypertension, who were less frequently admitted in 2020 than in 2019. Furthermore, the pandemic was associated with a significant increase in door-to-balloon and total ischemia times, which may have contributed to the higher mortality during the pandemic. CONCLUSIONS: The COVID-19 pandemic had significant impact on the treatment of patients with STEMI, with a 19% reduction in PPCI procedures, especially among patients suffering from hypertension, and a longer delay to treatment, which may have contributed to the increased mortality during the pandemic.

RESUMO

AIM: Primary percutaneous coronary intervention (PCI) is the optimal reperfusion strategy to manage ST-elevation myocardial infarction (STEMI). Where timely primary PCI cannot be achieved, an initial pharmacological reperfusion strategy is recommended with subsequent transfer to a PCI-capable hospital. The study aim was to assess STEMI outcomes according to the interventional capability of the New Zealand hospital to which patients initially present. METHODS: Nine thousand four hundred and eighty-eight New Zealand patients, aged 20-79 years, admitted with STEMI to a public hospital were identified. Patients were categorised into three groups-metropolitan hospitals with all-hours access to primary PCI (routine primary PCI cohort), metropolitan hospitals without routine access to PCI, and rural hospitals. The primary outcome was all-cause mortality. Secondary outcomes were major adverse cardiac events (MACE) and major bleeding. RESULTS: Invasive coronary angiography was more frequent in the routine primary PCI cohort compared to metropolitan hospitals without routine access to PCI and rural hospitals (90.6 vs 83.0 vs 85.0% respectively; p<0.001) and occurred more commonly on the day of admission (78.9 vs 28.7 vs 25.7% respectively; p<0.001). There were no differences in multivariable adjusted all-cause mortality, MACE or major bleeding between patients admitted to any of the hospital groupings. CONCLUSION: Outcomes after STEMI in New Zealand are similar regardless of the interventional capability of the hospital where they first present.

RESUMO

OBJECTIVES: To understand the impact of COVID-19 on delivery and outcomes of primary percutaneous coronary intervention (PPCI). Furthermore, to compare clinical presentation and outcomes of patients with ST-segment elevation myocardial infarction (STEMI) with active COVID-19 against those without COVID-19. METHODS: We systematically analysed 348 STEMI cases presenting to the PPCI programme in London during the peak of the pandemic (1 March to 30 April 2020) and compared with 440 cases from the same period in 2019. Outcomes of interest included ambulance response times, timeliness of revascularisation, angiographic and procedural characteristics, and in-hospital clinical outcomes RESULTS: There was a 21% reduction in STEMI admissions and longer ambulance response times (87 (62-118) min in 2020 vs 75 (57-95) min in 2019, p<0.001), but that this was not associated with a delays in achieving revascularisation once in hospital (48 (34-65) min in 2020 vs 48 (35-70) min in 2019, p=0.35) or increased mortality (10.9% (38) in 2020 vs 8.6% (38) in 2019, p=0.28). 46 patients with active COVID-19 were more thrombotic and more likely to have intensive care unit admissions (32.6% (15) vs 9.3% (28), OR 5.74 (95%CI 2.24 to 9.89), p<0.001). They also had increased length of stay (4 (3-9) days vs 3 (2-4) days, p<0.001) and a higher mortality (21.7% (10) vs 9.3% (28), OR 2.72 (95% CI 1.25 to 5.82), p=0.012) compared with patients having PPCI without COVID-19. CONCLUSION: These findings suggest that PPCI pathways can be maintained during unprecedented healthcare emergencies but confirms the high mortality of STEMI in the context of concomitant COVID-19 infection characterised by a heightened state of thrombogenicity.

RESUMO

OBJECTIVE: Delayed admission of myocardial infarction (MI) patients is an important prognostic factor. In the present nationwide registry (TURKMI-2), we evaluated the treatment delays and outcomes of patients with acute MI during the Covid-19 pandemic and compaired with a recentpre-pandemic registry (TURKMI-1). METHODS: The pandemic and pre-pandemic studies were conducted prospectively as 15-day snapshot registries in the same 48 centers. The inclusion criteria for both registries were aged ≥18 years and a final diagnosis of acute MI (AMI) with positive troponin levels. The only difference between the 2 registries was that the pre-pandemic (TURKMI-1) registry (n=1872) included only patients presenting within the first 48 hours after symptom-onset. TURKMI-2 enrolled all consecutive patients (n=1113) presenting with AMI during the pandemic period. RESULTS: A comparison of the patients with acute MI presenting within the 48-hour of symptom-onset in the pre-pandemic and pandemic registries revealed an overall 47.1% decrease in acute MI admissions during the pandemic. Median time from symptom-onset to hospital-arrival increased from 150 min to 185 min in patients with ST elevation MI (STEMI) and 295 min to 419 min in patients presenting with non-STEMI (NSTEMI) (p-values <0.001). Door-to-balloon time was similar in the two periods (37 vs. 40 min, p=0.448). In the pandemic period, percutaneous coronary intervention (PCI) decreased, especially in the NSTEMI group (60.3% vs. 47.4% in NSTEMI, p<0.001; 94.8% vs. 91.1% in STEMI, p=0.013) but the decrease was not significant in STEMI patients admitted within 12 hours of symptom-onset (94.9% vs. 92.1%; p=0.075). In-hospital major adverse cardiac events (MACE) were significantly increased during the pandemic period [4.8% vs. 8.9%; p<0.001; age- and sex-adjusted Odds ratio (95% CI) 1.96 (1.20-3.22) for NSTEMI, p=0.007; and 2.08 (1.38-3.13) for STEMI, p<0.001]. CONCLUSION: The present comparison of 2 nationwide registries showed a significant delay in treatment of patients presenting with acute MI during the COVID-19 pandemic. Although PCI was performed in a timely fashion, an increase in treatment delay might be responsible for the increased risk of MACE. Public education and establishing COVID-free hospitals are necessary to overcome patients' fear of using healthcare services and mitigate the potential complications of AMI during the pandemic.

RESUMO

An increase in coronavirus disease (COVID-19) infections prompted Level 4 lockdown throughout New Zealand from 25 March 2020. We have investigated trends in coronary and electrophysiology (EP) procedures before and during this lockdown. The number of acute procedures for ST elevation myocardial infarction remained stable. In contrast, the number of in-patient angiograms and percutaneous intervention procedures fell by 53% compared with the previous 4 weeks in 2020 and by 56% compared with the corresponding period in 2019. Further study is required to determine the reasons for these trends.

RESUMO

BACKGROUND The efficacy of telemedicine in reducing delay times and short-term adverse clinical outcomes in patients with ST segment elevation myocardial infarction (STEMI) during the coronavirus disease 2019 (COVID-19) pandemic is unclear. This study compared outcomes in patients with STEMI who had percutaneous coronary intervention (PCI) and the use of a telemedicine app from August 2019 to March 2020 at a single center in Beijing, China. MATERIAL AND METHODS A total of 243 patients with STEMI who underwent PCI were consecutively enrolled and divided into 2 groups according to the date, before or after the pandemic. The 2 groups were further divided into patients who used the app for consulting and those who did not. RESULTS The time from symptom onset to calling an ambulance (SCT), door to balloon time (DTB), and total ischemia time (TIT) were significantly prolonged in patients after the pandemic. Patients who used the app had shorter SCT, DTB, and TIT before and after the pandemic compared to those who did not. Adverse clinical outcomes were significantly higher after compared with before the pandemic, despite the incidence rate of stroke, any revascularization, and stent thrombosis. However, there was no significant difference in short-term adverse clinical outcomes between patients who used the app and those who did not before and after the pandemic. CONCLUSIONS Telemedicine reduced the delay time of STEMI patients during the COVID-19 pandemic. The difference in short-term adverse clinical outcomes was not statistically significant between patients who used the app and those who did not.

RESUMO

Background: The white blood cell count to mean platelet volume ratio (WMR) is an indicator of inflammation in patients with atherosclerotic disease. Residual SYNTAX Score (RSS) is an objective measure of degree and complexity of residual stenosis after percutaneous coronary intervention (PCI). We investigated the relationship between WMR and clinical prognosis and RSS in patients undergoing primary percutaneous coronary intervention (P-PCI). Method: Between June 2015 and December 2018, 537 patients who underwent primary PCI were evaluated for in-hospital events, and 477 patients were evaluated for clinical events during follow-up after discharge. The endpoint of our study is major adverse cardiac events (MACEs) seen in the in-hospital and follow-up periods. Results: In our study, 537 patients were stratified into two groups according to admission median WMR. There were 268 patients in the low WMR group (WMR < 1286) and 269 patients in the high WMR group (WMR ≥ 1286). RSS (p = 0.01) value of the high WMR group was higher than that of the low WMR group. The rates of in-hospital MACE (p = 0.001), cardiac death (p < 0.001), decompansated heart failure (0.007), and ventricular tachycardia/fibrillation (p = 0.003) were higher in the high WMR group than in the low WMR group. The follow-up MACEs (p = 0.043), cardiac death (p = 0.026), and reinfarction (p = 0.031) ratio were higher in the high WMR group. In ROC analysis, cut-off values of in-hospital and follow-up MACEs were >1064 (sensitivity: 83.12%, and specificity: 36.29%) and >1130 (sensitivity: 69.15%, and specificity: 44.91%), respectively. The Kaplan-Meier analysis showed that the high WMR group had the significantly lowest MACE-free survival rate (log-rank test, p = 0.006). A moderate correlation was observed between WMR and RSS (r: 456, p = 0.002). Conclusion: A higher WMR value on admission was associated with worse outcomes in patients with P-PCI and independently predicted for follow-up MACEs. The WMR provides both a rapid and an easily obtainable parameter to identify reliably high-risk patients who underwent primary percutaneous coronary intervention due to STEMI.

RESUMO

BACKGROUND: The objective of the study was to identify any changes in primary percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI) in England by analysing procedural numbers, clinical characteristics and patient outcomes during the COVID-19 pandemic. METHODS: We conducted a retrospective cohort study of patients who underwent PCI in England between January 2017 and April 2020 in the British Cardiovascular Intervention Society-National Institute of Cardiovascular Outcomes Research database. Analysis was restricted to 44 hospitals that reported contemporaneous activity on PCI. Only patients with primary PCI for STEMI were included in the analysis. RESULTS: A total of 34 127 patients with STEMI (primary PCI 33 938, facilitated PCI 108, rescue PCI 81) were included in the study. There was a decline in the number of procedures by 43% (n=497) in April 2020 compared with the average monthly procedures between 2017 and 2019 (n=865). For all patients, the median time from symptom to hospital showed increased after the lockdown (150 (99-270) vs 135 (89-250) min, p=0.004) and a longer door-to-balloon time after the lockdown (48 (21-112) vs 37 (16-94) min, p<0.001). The in-hospital mortality rate was 4.8% before the lockdown and 3.5% after the lockdown (p=0.12). Following adjustment for baseline characteristics, no differences were observed for in-hospital death (OR 0.87, 95% CI 0.45 to 1.68, p=0.67) and major adverse cardiovascular events (OR 0.71, 95% CI 0.39 to 1.32, p=0.28). CONCLUSIONS: Following the lockdown in England, we observed a decline in primary PCI procedures for STEMI and increases in overall symptom-to-hospital and door-to-balloon time for patients with STEMI. Restructuring health services during COVID-19 has not adversely influenced in-hospital outcomes.

RESUMO

The current COVID-19 crisis has significantly impacted healthcare systems worldwide. There has been a palpable increase in public avoidance of hospitals, which has interfered in timely care of critical cardiovascular conditions. Complications from late presentation of myocardial infarction, which had become a rarity, resurfaced during the pandemic. We present two such encounters that occurred due to delay in seeking medical care following myocardial infarction due to the fear of contracting COVID-19 in the hospital. Moreover, a comprehensive review of literature is performed to illustrate the potential factors delaying and decreasing timely presentations and interventions for time-dependent medical emergencies like ST-segment elevation myocardial infarction (STEMI). We emphasise that clinicians should remain vigilant of encountering rare and catastrophic complications of STEMI during this current era of COVID-19 pandemic.

RESUMO

There has been a huge impact of the COVID-19 pandemic on global healthcare systems. Advisories across the world have appealed to people to stay at home and observe social distancing to slow down the pandemic. However it is important to realize as to how this is affecting acute cardiovascular care. Recent studies from Europe and USA have reported > 50% reduction in hospital admissions for ACS and declining rates of coronary interventions. The possible reasons for this noticeable reduction in patients with ACS/STEMI during the COVID-19 pandemic are multi-factorial. On one hand, it is due to change in thresholds for referring patients of ACS/STEMI for cardiac catheterization, with fibrinolysis being acceptable for many stable STEMI patients and conservative management being preferred for NSTEMI patients. Theories abound on how "staying at home" strategy may have led to an reduction in acute coronary events due to healthier lifestyle, better compliance and reduced stress. Realistically however, a more disquieting reason would be a "pseudo-reduction" ie. the incidence of ACS/STEMI is actually the same, but these patients are staying away from hospitals due to fear of contracting the infection. Lockdown restrictions have also limited transport options for patients seeking to reach hospitals in time. Healthcare systems need to be prepared for an anticipated downstream deluge of such untreated patients who may present with sequelae like heart failure, reinfarction, arrhythmias, mechanical complications etc. Scientific societies should have proactive campaigns to alleviate patient concerns, and encourage them to seek timely medical attention despite the COVID-19 pandemic.

RESUMO

The aim of the present study was to investigate the long-term impact of early intravenous metoprolol in ST-segment elevation myocardial infarction (STEMI) patients in terms of left ventricular (LV) strain with feature-tracking cardiovascular magnetic resonance (CMR) and its association with prognosis. A total of 270 patients with first anterior STEMI enrolled in the randomized METOCARD-CNIC clinical trial, assigned to receive up to 15 mg intravenous metoprolol before primary percutaneous coronary intervention versus conventional STEMI therapy, were included. LV global circumferential (GCS) and longitudinal (GLS) strain were assessed with feature-tracking CMR at 1 week after STEMI in 215 patients. The occurrence of major adverse cardiac events (MACE) at 5-year follow-up was the primary end point. Among 270 patients enrolled, 17 of 139 patients assigned to metoprolol arm and 31 of 131 patients assigned to control arm experienced MACE (hazard ratio [HR] 0.500, 95% confidence interval [CI] 0.277 to 0.903; p = 0.022). Impaired LV GCS and GLS strain were significantly associated with increased occurrence of MACE (GCS: HR 1.208, 95% CI 1.076 to 1.356, p =0.001; GLS: HR 1.362, 95% CI 1.180 to 1.573, p < 0.001). On multivariable analysis, LV GLS provided incremental prognostic value over late gadolinium enhancement (LGE) and LV ejection fraction (LVEF) (LGE + LVEF chi-square = 12.865, LGE + LVEF + GLS chi-square = 18.459; p =0.012). Patients with GLS ≥-11.5% (above median value) who received early intravenous metoprolol were 64% less likely to experience MACE than their counterparts with same degree of GLS impairment (HR 0.356, 95% CI 0.129 to 0.979; p = 0.045). In conclusion, early intravenous metoprolol has a long-term beneficial prognostic effect, particularly in patients with severely impaired LV systolic function. LV GLS with feature-tracking CMR early after percutaneous coronary intervention offers incremental prognostic value over conventional CMR parameters in risk stratification of STEMI patients.

RESUMO

The pandemic of coronavirus disease 2019 (COVID-19) has become a public health emergency of international concern. During this time, the management of people with acute coronary syndromes (ACS) and COVID-19 has become a global issue, especially since preexisting cardiovascular disease is a risk factor for the presence and the severity of COVID-19. The number of people with ST- elevation myocardial infarction (STEMI) has decreased during the pandemic and delays in the time looking for medical care have been reported. In addition, the diagnosis of ACS may have been difficult due to possible underlying myocarditis or other clinical entities. Regarding management of people with STEMI, although the superiority of primary percutaneous coronary intervention (PCI) over thrombolysis is well established, the notable exposure risks due to absence of negative pressure in catheterization rooms and the increased difficulty in fine manipulation on guidewires under proper protection equipment may contribute to the relatively secondary role of PCI during the COVID-19 pandemic; thus, fibrinolytic therapy or robotic-assisted PCI in early presenting STEMI patients may have an alternative role during this period if prevention measures cannot be taken. Healthcare stuff should take the proper measures to avoid the spread of and their exposure to the virus.
