BACKGROUND AND AIMS: SARS-Cov-2 predisposes patients to thrombotic complications, due to excessive inflammation, endothelial dysfunction, platelet activation, and coagulation/fibrinolysis disturbances. The aim of the present study was to evaluate clinical characteristics and prognostic impact of SARS-CoV-2 positivity among STEMI patients undergoing primary percutaneous coronary intervention (PPCI). METHODS: We selected SARS-CoV-2 positive patients included in the ISACS-STEMI COVID-19, a retrospective multicenter European registry including 6609 STEMI patients treated with PPCI from March 1st until April 30th, in 2019 and 2020. As a reference group, we randomly sampled 5 SARS-Cov-2 negative patients per each SARS-CoV-2 positive patient, individually matched for age, sex, and hospital/geographic area. Study endpoints were in-hospital mortality, definite stent thrombosis, heart failure. RESULTS: Our population is represented by 62 positive SARS-CoV-2 positive patients who were compared with a matched population of 310 STEMI patients. No significant difference was observed in baseline characteristics or the modality of access to the PCI center. In the SARS-CoV-2 positive patients, the culprit lesion was more often located in the RCA (p < 0.001). Despite similar pre and postprocedural TIMI flow, we observed a trend in higher use of GP IIb-IIIa inhibitors and a significantly higher use of thrombectomy in the SARS-CoV-2 positive patients. SARS-CoV-2 positivity was associated with a remarkably higher in hospital mortality (29% vs 5.5%, p < 0.001), definite in-stent thrombosis (8.1% vs 1.6%, p = 0.004) and heart failure (22.6% vs 10.6%, p = 0.001) that was confirmed after adjustment for confounding factors. CONCLUSIONS: Our study showed that among STEMI patients, SARS-CoV-2 positivity is associated with larger thrombus burden, a remarkably higher mortality but also higher rates of in-stent thrombosis and heart failure.

BACKGROUND: Concerns have been raised on a potential interaction between renin-angiotensin system inhibitors (RASI) and the susceptibility to coronavirus disease 2019 (COVID-19). No data have been so far reported on the prognostic impact of RASI in patients suffering from ST-elevation myocardial infarction (STEMI) during COVID-19 pandemic, which was the aim of the present study. METHODS: STEMI patients treated with primary percutaneous coronary intervention (PPCI) and enrolled in the ISACS-STEMI COVID-19 registry were included in the present sub-analysis and divided according to RASI therapy at admission. RESULTS: Our population is represented by 6095 patients, of whom 3654 admitted in 2019 and 2441 in 2020. No difference in the prevalence of SARSCoV2 infection was observed according to RASI therapy at admission (2.5% vs 2.1%, p = 0.5), which was associated with a significantly lower mortality (adjusted OR [95% CI]=0.68 [0.51-0.90], P = 0.006), confirmed in the analysis restricted to 2020 (adjusted OR [95% CI]=0.5[0.33-0.74], P = 0.001). Among the 5388 patients in whom data on in-hospital medication were available, in-hospital RASI therapy was associated with a significantly lower mortality (2.1% vs 16.7%, OR [95% CI]=0.11 [0.084-0.14], p < 0.0001), confirmed after adjustment in both periods. Among the 62 SARSCoV-2 positive patients, RASI therapy, both at admission or in-hospital, showed no prognostic effect. CONCLUSIONS: This is the first study to investigate the impact of RASI therapy on the prognosis and SARSCoV2 infection of STEMI patients undergoing PPCI during the COVID-19 pandemic. Both pre-admission and in-hospital RASI were associated with lower mortality. Among SARSCoV2-positive patients, both chronic and in-hospital RASI therapy showed no impact on survival.

BACKGROUND: It has been suggested the COVID pandemic may have indirectly affected the treatment and outcome of STEMI patients, by avoidance or significant delays in contacting the emergency system. No data have been reported on the impact of diabetes on treatment and outcome of STEMI patients, that was therefore the aim of the current subanalysis conducted in patients included in the International Study on Acute Coronary Syndromes-ST Elevation Myocardial Infarction (ISACS-STEMI) COVID-19. METHODS: The ISACS-STEMI COVID-19 is a retrospective registry performed in European centers with an annual volume of > 120 primary percutaneous coronary intervention (PCI) and assessed STEMI patients, treated with primary PCI during the same periods of the years 2019 versus 2020 (March and April). Main outcomes are the incidences of primary PCI, delayed treatment, and in-hospital mortality. RESULTS: A total of 6609 patients underwent primary PCI in 77 centers, located in 18 countries. Diabetes was observed in a total of 1356 patients (20.5%), with similar proportion between 2019 and 2020. During the pandemic, there was a significant reduction in primary PCI as compared to 2019, similar in both patients with (Incidence rate ratio (IRR) 0.79 (95% CI: 0.73-0.85, p < 0.0001) and without diabetes (IRR 0.81 (95% CI: 0.78-0.85, p < 0.0001) (p int = 0.40). We observed a significant heterogeneity among centers in the population with and without diabetes (p < 0.001, respectively). The heterogeneity among centers was not related to the incidence of death due to COVID-19 in both groups of patients. Interaction was observed for Hypertension (p = 0.024) only in absence of diabetes. Furthermore, the pandemic was independently associated with a significant increase in door-to-balloon and total ischemia times only among patients without diabetes, which may have contributed to the higher mortality, during the pandemic, observed in this group of patients. CONCLUSIONS: The COVID-19 pandemic had a significant impact on the treatment of patients with STEMI, with a similar reduction in primary PCI procedures in both patients with and without diabetes. Hypertension had a significant impact on PCI reduction only among patients without diabetes. We observed a significant increase in ischemia time and door-to-balloon time mainly in absence of diabetes, that contributed to explain the increased mortality observed in this group of patients during the pandemic.

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.

BACKGROUND: Routine thrombus aspiration in patients undergoing primary percutaneous coronary intervention (PCI) for ST-segment elevation myocardial infarction (STEMI) does not improve clinical outcomes. However, there is remaining uncertainty about the potential benefit in those patients with high thrombus burden, where there is a biological rationale for greater benefit. OBJECTIVES: The purpose of this study was to evaluate the benefit of thrombus aspiration among STEMI patients with high thrombus burden. METHODS: TOTAL (ThrOmbecTomy with PCI vs. PCI ALone in patients with STEMI) was a randomized trial of routine manual thrombectomy versus PCI alone in patients with STEMI (n = 10,732). High thrombus burden (Thrombolysis In Myocardial Infarction thrombus grade ≥3) was a pre-specified subgroup. RESULTS: The primary outcome of cardiovascular (CV) death, MI, cardiogenic shock, or heart failure was not different at 1 year with thrombus aspiration in patients with high thrombus burden (8.1% vs. 8.3% thrombus aspiration; hazard ratio [HR]: 0.97; 95% confidence interval [CI]: 0.84 to 1.13) or low thrombus burden (6.0% vs. 5.0% thrombus aspiration; HR: 1.22; 95% CI: 0.73 to 2.05; interaction p = 0.41). However, among patients with high thrombus burden, stroke at 30 days was more frequent with thrombus aspiration (31 [0.7%] thrombus aspiration vs. 16 [0.4%] PCI alone, HR: 1.90; 95% CI: 1.04 to 3.48). In the high thrombus burden group, thrombus aspiration did not significantly improve CV mortality at 30 days (HR: 0.78; 95% CI: 0.61 to 1.01; p = 0.06) and at 1 year (HR: 0.88; 95% CI: 0.72 to 1.09; p = 0.25). Irrespective of treatment assignment, high thrombus burden was an independent predictor of death (HR: 1.78; 95% CI: 1.05 to 3.01). CONCLUSIONS: In patients with high thrombus burden, routine thrombus aspiration did not improve outcomes at 1 year and was associated with an increased rate of stroke. High thrombus burden is still an important predictor of outcome in STEMI. (A Trial of routine aspiration ThrOmbecTomy with PCI vs. PCI ALone in patients with STEMI [TOTAL]; NCT01149044).

BACKGROUND: Two large trials have reported contradictory results at 1 year after thrombus aspiration in ST elevation myocardial infarction (STEMI). In a 1-year follow-up of the largest randomised trial of thrombus aspiration, we aimed to clarify the longer-term benefits, to help guide clinical practice. METHODS: The trial of routine aspiration ThrOmbecTomy with PCI versus PCI ALone in Patients with STEMI (TOTAL) was a prospective, randomised, investigator-initiated trial of routine manual thrombectomy versus percutaneous coronary intervention (PCI) alone in 10,732 patients with STEMI. Eligible adult patients (aged ≥18 years) from 87 hospitals in 20 countries were enrolled and randomly assigned (1:1) within 12 h of symptom onset to receive routine manual thrombectomy with PCI or PCI alone. Permuted block randomisation (with variable block size) was done by a 24 h computerised central system, and was stratified by centre. Participants and investigators were not masked to treatment assignment. The trial did not show a difference at 180 days in the primary outcome of cardiovascular death, myocardial infarction, cardiogenic shock, or heart failure. However, the results showed improvements in the surrogate outcomes of ST segment resolution and distal embolisation, but whether or not this finding would translate into a longer term benefit remained unclear. In this longer-term follow-up of the TOTAL study, we report the results on the primary outcome (cardiovascular death, myocardial infarction, cardiogenic shock, or heart failure) and secondary outcomes at 1 year. Analyses of the primary outcome were by modified intention to treat and only included patients who underwent index PCI. This trial is registered with ClinicalTrials.gov, number NCT01149044. FINDINGS: Between Aug 5, 2010, and July 25, 2014, 10,732 eligible patients were enrolled and randomly assigned to thrombectomy followed by PCI (n=5372) or to PCI alone (n=5360). After exclusions of patients who did not undergo PCI in each group (337 in the PCI and thrombectomy group and 331 in the PCI alone group), the final study population comprised 10,064 patients (5035 thrombectomy and 5029 PCI alone). The primary outcome at 1 year occurred in 395 (8%) of 5035 patients in the thrombectomy group compared with 394 (8%) of 5029 in the PCI alone group (hazard ratio [HR] 1·00 [95% CI 0·87-1·15], p=0·99). Cardiovascular death within 1 year occurred in 179 (4%) of the thrombectomy group and in 192 (4%) of 5029 in the PCI alone group (HR 0·93 [95% CI 0·76-1·14], p=0·48). The key safety outcome, stroke within 1 year, occurred in 60 patients (1·2%) in the thrombectomy group compared with 36 (0·7%) in the PCI alone group (HR 1·66 [95% CI 1·10-2·51], p=0·015). INTERPRETATION: Routine thrombus aspiration during PCI for STEMI did not reduce longer-term clinical outcomes and might be associated with an increase in stroke. As a result, thrombus aspiration can no longer be recommended as a routine strategy in STEMI.

BACKGROUND: During primary percutaneous coronary intervention (PCI), manual thrombectomy may reduce distal embolization and thus improve microvascular perfusion. Small trials have suggested that thrombectomy improves surrogate and clinical outcomes, but a larger trial has reported conflicting results. METHODS: We randomly assigned 10,732 patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary PCI to a strategy of routine upfront manual thrombectomy versus PCI alone. The primary outcome was a composite of death from cardiovascular causes, recurrent myocardial infarction, cardiogenic shock, or New York Heart Association (NYHA) class IV heart failure within 180 days. The key safety outcome was stroke within 30 days. RESULTS: The primary outcome occurred in 347 of 5033 patients (6.9%) in the thrombectomy group versus 351 of 5030 patients (7.0%) in the PCI-alone group (hazard ratio in the thrombectomy group, 0.99; 95% confidence interval [CI], 0.85 to 1.15; P=0.86). The rates of cardiovascular death (3.1% with thrombectomy vs. 3.5% with PCI alone; hazard ratio, 0.90; 95% CI, 0.73 to 1.12; P=0.34) and the primary outcome plus stent thrombosis or target-vessel revascularization (9.9% vs. 9.8%; hazard ratio, 1.00; 95% CI, 0.89 to 1.14; P=0.95) were also similar. Stroke within 30 days occurred in 33 patients (0.7%) in the thrombectomy group versus 16 patients (0.3%) in the PCI-alone group (hazard ratio, 2.06; 95% CI, 1.13 to 3.75; P=0.02). CONCLUSIONS: In patients with STEMI who were undergoing primary PCI, routine manual thrombectomy, as compared with PCI alone, did not reduce the risk of cardiovascular death, recurrent myocardial infarction, cardiogenic shock, or NYHA class IV heart failure within 180 days but was associated with an increased rate of stroke within 30 days.

AIMS: TOTAL (N = 10 732), a randomized trial of routine manual thrombectomy vs. percutaneous coronary intervention alone in ST elevation myocardial infarction, showed no difference in the primary efficacy outcome but a significant increase in stroke. We sought to understand these findings. METHODS AND RESULTS: A detailed analysis of stroke timing, stroke severity, and stroke subtype was performed. Strokes were adjudicated by neurologists blinded to treatment assignment. Stroke within 30 days, the primary safety outcome, was increased [33 (0.7%) vs. 16 (0.3%), hazard ratio (HR) 2.06; 95% confidence interval (CI) 1.13-3.75]. The difference in stroke was apparent within 48 h [15 (0.3%) vs. 5 (0.1%), HR 3.00; 95% CI 1.09-8.25]. There was an increase in strokes within 180 days with minor or no disability (Rankin 0-2) [18 (0.4%) vs. 13 (0.3%) HR 1.38; 95% CI 0.68-2.82] and in strokes with major disability or fatal (Rankin 3-6) [35 (0.7%) vs. 13 (0.3%), HR 2.69; 95% CI 1.42-5.08]. Most of the absolute difference was due to an increase in ischaemic strokes within 180 days [37 (0.7%) vs. 21 (0.4%), HR 1.71; 95% CI 1.03-3.00], but there was also an increase in haemorrhagic strokes [10 (0.2%) vs. 2 (0.04%), HR 4.98; 95% CI 1.09-22.7]. Patients that had a stroke had a mortality of 30.8% within 180 days vs. 3.4% without a stroke (P < 0.001). A meta-analysis of randomized trials (N = 21 173) showed an increase in risk of stroke (odds ratio 1.59; 95% CI 1.11-2.27) but a trend towards reduction in mortality odds ratio (odds ratio 0.87; 95% CI 0.76-1.00). CONCLUSION: Thrombectomy was associated with a significant increase in stroke. Based on these findings, future trials must carefully collect stroke to determine safety in addition to efficacy.
