The COVID-19 pandemic has put several healthcare systems under severe pressure. The present analysis investigates how the first wave of the COVID-19 pandemic affected the myocardial infarction (MI) ...network of Emilia-Romagna (Italy).
Based on Emilia-Romagna mortality registry and administrative data from all the hospitals from January 2017 to June 2020, we analysed: i) temporal trend in MI hospital admissions; ii) characteristics, management, and 30-day mortality of MI patients; iii) out-of-hospital mortality for cardiac cause.
Admissions for MI declined on February 22, 2020 (IRR -19.5%, 95%CI from -8.4% to -29.3%, p = 0.001), and further on March 5, 2020 (IRR -21.6%, 95%CI from -9.0% to -32.5%, p = 0.001). The return to pre-COVID-19 MI-related admission levels was observed from May 13, 2020 (IRR 34.3%, 95%CI 20.0%-50.2%, p<0.001). As compared to those before the pandemic, MI patients admitted during and after the first wave were younger and with fewer risk factors. The 30-day mortality remained in line with that expected based on previous years (ratio observed/expected was 0.96, 95%CI 0.84–1.08). MI patients positive for SARS-CoV-2 were few (1.5%) but showed poor prognosis (around 5-fold increase in 30-day mortality). In 2020, the number of out-of-hospital cardiac deaths was significantly higher (ratio observed/expected 1.17, 95%CI 1.08–1.27). The peak was reached in April.
In Emilia-Romagna, MI hospitalizations significantly decreased during the first wave of the COVID-19 pandemic. Management and outcomes of hospitalized MI patients remained unchanged, except for those with SARS-CoV-2 infection. A concomitant increase in the out-of-hospital cardiac mortality was observed.
None.
Objectives
To define the incidence of vascular complications (VC) after balloon aortic valvuloplasty (BAV) in recent years, and to compare the performance of two vascular closure devices (VCD).
...Background
VC remain the most frequent drawback of BAV and are associated with adverse clinical outcomes.
Methods
All BAV procedures performed at 2 high‐volume centers over a 6‐year period (n = 930) were collected in prospective registries and investigated to assess the incidence of Valve Academic Research Consortium‐2 (VARC‐2) defined VC. Incidence of life‐threatening, major and minor bleeding was also assessed. In‐hospital major adverse cardiac and cerebrovascular events (MACCE) rate (composite of in‐hospital death, myocardial infarction, TIA/stroke, and life‐threatening bleeding) as well as 30‐day survival was compared between a suture‐mediated closure system and a collagen plug hemostatic device.
Results
A 9 Fr arterial sheath was used in most of the patients (84.1%). Vascular closure was obtained with the Angio‐Seal in 643 patients (69.1%) and the ProGlide in 287 (30.9%). The overall incidence of major VC was 2.7%, and minor VC 6.6%, without significant differences between groups. The Angio‐Seal group was associated with a higher rate of small hematomas (6.9% vs. 3.5%, P = 0.042), whilst blood transfusions were more frequent in the ProGlide group (6.6% vs. 3.5%, P = 0.034). Rates of in‐hospital MACCE and 30‐day survival were similar. Use of either VCD was not independently associated with major VC.
Conclusions
VC rate after BAV is fairly low in experienced centers without major differences between the 2 most used VCD.
The causes of death within 1 year of hospital admission in patients with non–ST-segment elevation acute coronary syndromes are ill defined, particularly in patients aged ≥75 years. From January 2008 ...through May 2010, we enrolled 645 patients aged ≥75 years with non–ST-segment elevation acute coronary syndromes: 313 in a randomized trial comparing an early aggressive versus an initially conservative approach, and 332, excluded from the trial for specific reasons, in a parallel registry. Each death occurring during 1 year of follow-up was adjudicated by an independent committee. The mean age was 82 years in both study cohorts, and 53% were men. By the end of the follow-up period (median 369 days, interquartile range 345 to 391), 120 patients (18.6%) had died. The mortality was significantly greater in the registry (23.8% vs 13.1%, p = 0.001). The deaths were classified as cardiac in 94% of the cases during the index admission and 68% of the cases during the follow-up period. Eighty-six percent of the cardiac deaths were of ischemic origin. In a multivariate logistic regression model that included the variables present on admission in the whole study population, the ejection fraction (hazard ratio 0.95, 95% confidence interval 0.94 to 0.97; p <0.001), hemoglobin level (hazard ratio 0.85, 95% confidence interval 0.76 to 0.94; p = 0.001), older age (hazard ratio 1.05, 95% confidence interval 1.01 to 1.10, p = 0.010), and creatinine clearance (hazard ratio 0.99, 95% confidence interval 0.97 to 0.99; p = 0.030) were the independent predictors of all-cause death at 1 year. In conclusion, within 1 year after admission for non–ST-segment elevation acute coronary syndromes, most deaths in patients aged ≥75 years have a cardiac origin, mostly owing to myocardial ischemia.
Coronary chronic total occlusion (CTO) produces an important clinical problem, often treated with medical therapy or coronary artery bypass grafting. Recent clinical studies, both registries and ...randomized trials, demonstrated that percutaneous coronary interventions (PCI), could provide a valid therapeutic option. Nonetheless, significant reduction in all-cause mortality, cardiac mortality, myocardial infarction, MACE, and MACCE has not been demonstrated in the subgroups analysis of randomized trials. These analyses suggest that PCI for CTO should be reserved for patients with angina or with large areas of the myocardium with reversible ischaemia. Large randomized studies should search for a personalized approach, considering the risks and complexity of PCI in CTO, which should mainly consider the extension of the ischaemia and the viability of the myocardium.
Percutaneous revascularization of saphenous vein grafts (SVGs) remains a challenging task. Drug-eluting stents (DESs) have been shown to decrease the incidence of restenosis in de novo native ...coronary artery lesions. However, their clinical value in SVGs remains to be established. We compared long-term clinical outcomes of percutaneous coronary intervention with DESs and bare metal stents (BMSs) for de novo lesions in SVGs. In a large prospective, multicenter registry, 360 patients underwent stenting of a de novo lesion in SVGs using BMSs (288 patients) or DESs (72 patients). Incidence of major adverse cardiac events (MACEs), including all-cause mortality, reinfarction, and target vessel revascularization, was recorded at a 12-month follow-up. Compared with the DES group, patients receiving BMSs were more likely to be men, to have chronic renal insufficiency or higher Charlson scores, but less likely to have undergone previous percutaneous coronary intervention. Incidence of MACEs at 12-month follow-up was similar in the 2 groups (17.8% in DES group vs 20.3% in BMS group, respectively, p = 0.460). Cox regression analysis identified age, chronic renal failure, cardiogenic shock at presentation, and ostial location of stenosis as independent predictors of long-term MACEs. In conclusion, our data suggest that rates of 12-month MACEs associated with the use of DESs and BMSs are similar in patients undergoing treatment of de novo lesions in SVGs.

We compared the clinical outcome of sirolimus-eluting stents (SES) and polymer-coated paclitaxel-eluting stents (PES) in a real-world scenario. Overall, 1,676 consecutive patients with de novo coronary lesions treated with SES (n = 992) or PES (n = 684) were enrolled in a prospective multicenter registry. A considerable number of patients presented complex clinical, angiographic, and procedural characteristics. At 1-year follow-up, SES utilization reduced the risk of adverse events by 44% and the risk of new revascularizations by 55% compared to PES. This study suggests better clinical outcome of SES compared to PES in the treatment of real-world high-complex patients.
We compared the clinical outcome of sirolimus-eluting stents (SES) and paclitaxel-eluting stents (PES) in a real-world scenario.
In selected patients, SES has been associated with lower late luminal loss than PES. Whether this emerging biological difference could translate into different clinical efficacy in daily practice is presently unknown.
This analysis included 1,676 consecutive patients with de novo coronary lesions treated solely with drug-eluting stents (SES = 992; PES = 684). All patients were enrolled in a dynamic prospective registry comprising 13 hospitals. We assessed the cumulative incidence of major adverse cardiac events (MACE), defined as death, myocardial infarction (MI), and target vessel revascularization (TVR) during follow-up.
Overall, 29% of the patients had diabetes, 23% had prior MI, and 9% had poor left ventricular function. ST-segment elevation MI was diagnosed at admission in 12%. Multivessel intervention was performed in 16%. At 1-year follow-up, SES was associated with a reduced incidence of MACE (9.2% SES vs. 14.1% PES; p = 0.007) and TVR (5.0% SES vs. 10.0% PES; p = 0.0008) compared to PES. A propensity analysis with many clinical and angiographic variables was carried out to adjust for baseline differences. In this analysis, SES was associated with a 44% risk reduction of MACE (hazard ratio 0.56, 95% confidence interval 0.39 to 0.78) and a 55% reduction of TVR (hazard ratio 0.45, 95% confidence interval 0.29 to 0.70). This result was consistent across most subgroups tested. Similar rates of death and MI were observed in the 2 treatment groups.
In this large real-world population, SES improved 1-year clinical results as compared to PES.
The aim of this study was to compare long term clinical outcome after left main stenting in a large real world population of patients treated with drug-eluting stents (DES) or bare-metal stents (BMS) ...in the setting of acute coronary syndromes. The advent of DES decreased the risk of unprotected left main coronary artery restenosis as compared with BMS, but safety concerns still exist, especially when high-risk patients presenting with acute coronary syndromes are considered. The Gruppo Italiano Studi Emodinamici-Societa' Italiana di Cardiologia Invasiva (GISE-SICI) registry is a retrospective, observational multicenter registry promoted by the Italian Society of Invasive Cardiology in which 19 high-volume participating centers enrolled 1,453 consecutive patients who underwent percutaneous coronary intervention on unprotected left main coronary artery between January 2002 and December 2006. From the registry, a total of 849 consecutive patients presenting with unstable angina or non–ST-segment elevation myocardial infarction who underwent DES (n = 611) or BMS (n = 238) implantation were analyzed with extensive multivariable and propensity-score adjustments. At 3-year follow-up, the adjusted hazard ratio for the risk of mortality after DES implantation relative to BMS implantation was 0.90 (95% confidence intervals CI 0.59 to 1.38, p = 0.617), and the adjusted hazard ratio for the risk of cardiac mortality was 0.75 (95% CI 0.45 to 1.27, p = 0.287). DES were associated with significant reduction of myocardial infarction (hazard ratio 0.37, 95% CI 0.17 to 0.81, p = 0.009) and target lesion revascularization rates (hazard ratio 0.38, 95% CI 0.21 to 0.69, p = 0.001). Younger age, low ejection fraction, an increase in the cardiac biomarkers, absence of diabetes, and bifurcations showed a significant interaction with assigned treatment regarding myocardial infarction. The treatment effects on target lesion revascularization were consistent across multiple subgroups, with the possible exception of patients with nonbifurcational lesions. In conclusion, in a large population of patients with acute coronary syndromes and unprotected left main coronary artery disease DES were more effective than BMS in reducing myocardial infarction and target lesion revascularization. There was no evidence of a significant reduction in mortality with DES versus BMS.
Abstract
Aims
Our aim was to describe the electrocardiographic features of critical COVID-19 patients.
Methods and results
We carried out a multicentric, cross-sectional, retrospective analysis of ...431 consecutive COVID-19 patients hospitalized between 10 March and 14 April 2020 who died or were treated with invasive mechanical ventilation. This project is registered on ClinicalTrials.gov (identifier: NCT04367129). Standard ECG was recorded at hospital admission. ECG was abnormal in 93% of the patients. Atrial fibrillation/flutter was detected in 22% of the patients. ECG signs suggesting acute right ventricular pressure overload (RVPO) were detected in 30% of the patients. In particular, 43 (10%) patients had the S1Q3T3 pattern, 38 (9%) had incomplete right bundle branch block (RBBB), and 49 (11%) had complete RBBB. ECG signs of acute RVPO were not statistically different between patients with (n = 104) or without (n=327) invasive mechanical ventilation during ECG recording (36% vs. 28%, P = 0.10). Non-specific repolarization abnormalities and low QRS voltage in peripheral leads were present in 176 (41%) and 23 (5%), respectively. In four patients showing ST-segment elevation, acute myocardial infarction was confirmed with coronary angiography. No ST-T abnormalities suggestive of acute myocarditis were detected. In the subgroup of 110 patients where high-sensitivity troponin I was available, ECG features were not statistically different when stratified for above or below the 5 times upper reference limit value.
Conclusions
The ECG is abnormal in almost all critically ill COVID-19 patients and shows a large spectrum of abnormalities, with signs of acute RVPO in 30% of the patients. Rapid and simple identification of these cases with ECG at hospital admission can facilitate classification of the patients and provide pathophysiological insights.
BACKGROUND—Elderly patients are at elevated risk of both ischemic and bleeding complications after an acute coronary syndrome (ACS), and display higher on-clopidogrel platelet reactivity as compared ...to younger patients. Prasugrel 5 mg provides more predictable platelet inhibition, as compared to clopidogrel, in the elderly, suggesting the possibility of reducing ischemic events without increasing bleeding.
METHODS—In a multicenter, randomized, open-label, blinded-endpoint trial, we compared a once daily maintenance dose of prasugrel 5 mg with the standard clopidogrel 75 mg in patients >74 years with ACS undergoing percutaneous coronary intervention (PCI). The primary endpoint was the composite of mortality, myocardial infarction, disabling stroke and re-hospitalization for cardiovascular causes or bleeding within one year. The study was designed to demonstrate superiority of prasugrel 5 mg over clopidogrel 75 mg.
RESULTS—Enrolment was interrupted, according to pre-specified criteria, after a planned interim analysis, when 1443 patients (40% women, mean age 80 years) had been enrolled, with a median follow-up of 12 months, due to futility for efficacy. The primary endpoint occurred in 121 patients (17%) with prasugrel and 121 (16.6%) with clopidogrel (HR 1.007, 95% CI, 0.78-1.30; P =0.955). Definite/probable stent thrombosis rates were 0.7% with prasugrel vs 1.9% with clopidogrel (OR 0.36, C.I. 0.13-1.00, p=0.06). Bleeding Academic Research Consortium types ≥2 were 4.1% with prasugrel vs 2.7% with clopidogrel (OR 1.52, C.I. 0.85-3.16, P= 0.18).
CONCLUSIONS—The present study in elderly ACS patients showed no difference in the primary endpoint between reduced-dose prasugrel and standard-dose clopidogrel. However, the study should be interpreted in the light of premature termination of the trial.
CLINICAL TRIAL REGISTRATION—URLhttps://clinicaltrials.gov/ Unique IdentifierNCT01777503
The purpose of this study was to verify the impact on the number and characteristics of coronary invasive procedures for acute coronary syndrome (ACS) of two hub centers with cardiac catheterization ...facilities, during the first month of lockdown following the COVID-19 pandemic.
Procedural data of ACS patients admitted between 10 March and 10 April 2020 were compared with those of the same period of 2019.
We observed a 23.4% reduction in ACS admissions during 2020, with a decrease for both ST-elevation myocardial infarction (STEMI) (-5.6%) and non-ST-elevation myocardial infarction (-34.5%), albeit not statistically significant (P = 0.2). During the first 15 days of the examined periods, the reduction in ACS admissions reached 52.5% (-25% for STEMI and -70.3% for non-ST-elevation myocardial infarction, P = 0.04). Among STEMI patients, the rate of those with a time delay from symptoms onset longer than 180 min was significantly higher during the lockdown period (P = 0.01). Radiograph exposure (P = 0.01) was higher in STEMI patients treated in 2020 with a slightly higher amount of contrast medium (P = 0.1) and number of stents implanted (P = 0.1), whereas the number of treated vessels was reduced (P = 0.03). Percutaneous coronary intervention procedural success and in-hospital mortality were not different between the two groups and in STEMI patients (P NS for all).
During the early phase, the COVID-19 outbreak was associated with a lower rate of admissions for ACS, with a substantial impact on the time delay presentation of STEMI patients, but apparently without affecting the in-hospital outcomes.
