Risk of incident heart failure after COVID-19 recovery: a systematic review and meta-analysis.

Patients recovered from COVID-19 have an increased incidence of cardiovascular disease and heart structural changes. The aim of the present manuscript is to assess the risk of incident heart failure (HF) after COVID-19 infection. Data were obtained searching MEDLINE and Scopus for all studies published at any time up to September 1, 2022 reporting the risk of incident HF in COVID-19 recovered patients. The cumulative post-COVID-19 incidence and risk of incident HF were pooled using a random effects model and presented with the corresponding 95% confidence interval (CI). Statistical heterogeneity was measured using the Higgins I2 statistic. Overall, 21,463,173 patients (mean age 54.5 years, 58.7% males) were analyzed. Among them, 1,628,424 had confirmed COVID-19 infection while the remaining 19,834,749 represented the controls. The mean length of follow-up was 9.2 months. A random effect model revealed a pooled incidence of post COVID-19 HF in 1.1% of cases (95% CI: 0.7-1.6, I2: 99.8%). Moreover, recovered COVID-19 patients showed an increased risk of incident HF (HR: 1.90, 95% CI: 1.54-3.24, p < 0.0001, I2 = 96.5%) in the same follow-up period. Meta-regression showed a direct relationship for the risk of incident HF using age (p = 0.001) and hypertension (HT) (p = 0.02) as moderators, while an inverse association was observed when the follow-up length was adopted as moderating variable (p = 0.01). COVID-19 survivors had an additional 90% risk of developing HF after COVID-19 infection in the long-term period. This risk was directly related with age and previous history of HT especially in the early post-acute phase of the infection.

Impact of clinical profile at admission on the outcomes in patients hospitalized for acute pulmonary embolism: data from the IPER Registry.

Acute pulmonary embolism (PE) is characterized by a large heterogeneity of clinical presentation and disease course. We investigate whether different symptom PE phenotypes in hemodynamically stable PE could be associated with 30-day mortality risk. Hemodynamically stable patients from the multicentre, prospective Italian Pulmonary Embolism Registry (IPER) (September 2006-August 2010) presenting the most common four clinical phenotypes (< 24 h onset dyspnoea, chest pain, pleuritic pain and phlebitis) at admission were included and compared to those who were asymptomatic at admission. Overall, 1365 (mean age 68.7 ± 15.3 years, 609 males) were evaluated. Recent onset dyspnoea (< 24 h), chest pain, pleuritic pain and phlebitis were observed in 28.4%, 19.7%, 12.9% and 25.2%, respectively while asymptomatic patients represented the remaining 13.6% of cases. PE presenting with recent dyspnoea onset and chest pain had a lower 30-day overall survival (log-rank p = 0.01 and p < 0.001, respectively). By contrast, there were no significant differences when comparing patients with pleuritic pain or phlebitis (log-rank p = 0.2). Similar findings were confirmed at the Cox multivariate regression analysis which indicated a higher mortality risk in patients with chest pain [HR 3.21, 95% CI 2.16-4.78, p < 0.001] or recent dyspnoea [HR 2.12, 95% CI 1.22-3.87, p = 0.002] independent of age, heart rate, presence of right ventricular dysfunction, positive cardiac troponin and administration of systemic thrombolysis. Hemodynamically stable PE patients presenting with chest pain or recent onset dyspnoea had a lower 30-day survival compared to those asymptomatic or presenting pleuritic or phlebitis pain.Trial registry ClinicalTrials.gov; No: NCT01604538).

ANMCO position paper on the management of hypercholesterolaemia in patients with acute coronary syndrome.

Patients suffering from acute coronary syndrome (ACS) present a high risk of recurrence and new adverse cardiovascular events after hospital discharge. Elevated plasma LDL-cholesterol (LDL-C) levels have been shown to be a causal factor for the development of coronary heart disease, and robust clinical evidence has documented that LDL-C levels decrease linearly correlates with a reduction in cardiovascular events. Recent studies have also demonstrated the safety and efficacy of an early and significant reduction in LDL-C levels in patients with ACS. In this position paper, Italian Association of Hospital Cardiologists proposes a decision algorithm on early adoption of lipid-lowering strategies at hospital discharge and short-term follow-up of patients with ACS, in the light of the multiple evidence generated in recent years on the treatment of hypercholesterolaemia and the available therapeutic options, considering current reimbursement criteria.

Prevalence of pre-existing peripheral artery disease in COVID-19 patients and relative mortality risk: Systematic review and meta-analysis.

INTRODUCTION: This study aims to assess prevalence and prognostic implications of pre-existing peripheral artery disease (PAD) in patients infected by the SARS-CoV-2 by means of a systematic review and meta-analysis. MATERIAL AND METHODS: We searched MEDLINE and Scopus to locate all the articles published up to 10 December 2021, reporting data on pre-existing PAD among COVID-19 survivors (S) and non survivors (NS). The pooled prevalence of pre-existing PAD in COVID-19 patients was calculated using a random effects model and presenting the related 95% confidence interval (CI), while the mortality risk was estimated using the Mantel-Haenszel random effects models with odds ratio (OR) and related 95% CI. Statistical heterogeneity was measured using the Higgins I2 statistic. RESULTS: Eight investigations, enrolling 13,776 COVID-19 patients (mean age: 67.1 years, 3.863 males), met the inclusion criteria and were included in the final analysis. The pooled prevalence of pre-existing PAD was 5.7% of cases (95% CI: 3.8-8.4%, p < 0.0001), with high heterogeneity (I2 = 84.5%), which was directly correlated with age (p < 0.0001), previous hypertension (p = 0.003), and dyslipidaemia (p = 0.02) as demonstrated by the meta-regression. Moreover, pre-existing PAD was significantly associated with higher risk of short-term death in patients with SARS-CoV-2 infection (OR: 2.78, 95% CI: 2.37-3.27, p < 0.0001 I2 = 0%); the sensitivity analysis confirmed yielded results. CONCLUSIONS: Pre-existing PAD represents a comorbidity in about 1 out of 6 COVID-19 patients, but it is associated with a twofold higher risk of short-term mortality.

Gender-related differences in clinical outcomes after either single or double left main bifurcation stenting.

We sought to examine the impact of gender differences in clinical outcomes at 3 years also comparing the role of double versus single stenting approach for the treatment of coronary unprotected LM bifurcation lesions. We retrospectively analyzed both the procedural and medical data of patients referred to our hub center for complex LM bifurcation disease, treated using Crossover provisional stenting, T or T-and-Protrusion (TAP), Culotte, and Nano-inverted-T (NIT) techniques between January 1st, 2008 and May 1st 2018. The main outcome of the study was to evaluate the association between gender and target lesion failure (TLF) based on the different stenting technique used. Five hundred and sixty-seven patients (251 females, mean age 70.0 ± 10 years, mean Syntax score 31.6 ± 6.3) were evaluated. Crossover, T or TAP, culotte and NIT techniques were performed in 171 (30.1%), 61 (10.7%), 98 (17.2%) and 237 (41.8%) patients, respectively with no differences in baseline and peri-procedural items among gender. At a mean follow-up of 37.1 ± 10.8 months (range 22.1-39.3 moths), the overall TLF rate, cardiovascular mortality and stent thrombosis were 12.1%, 3.1% and 1.0%, respectively. Female gender was associated with an increased rate of major bleeding when treated with double stent strategy (p = 0.02). No gender difference in TLF was noted among gender, independently from the stenting approach used. Among patients with ULM bifurcation disease undergoing PCI, TLF rates were not different between genders at 3-year follow-up either using a single or double stent technique.

ANMCO position paper 'Appropriateness of prescribing direct oral anticoagulants in stroke and systemic thromboembolism prevention in adult patients with non-valvular atrial fibrillation'.

The appropriateness of prescribing direct oral anticoagulants [dabigatran, rivaroxaban, apixaban, and edoxaban (DOACs)] is regulated on the criteria established in Phase III trials. These criteria are reported in the summary of the product characteristics of the four DOACs. In clinical practice, prescriptions are not always in compliance with established indications. In particular, the use of lower doses than those recommended in drug data sheets is not uncommon. Literature data show that the inappropriate prescription of reduced doses causes drug underexposure and up to a three-fold increase in the risk of stroke/ischaemic transient attack, systemic thromboembolism, and hospitalization. Possible causes of the deviation between the dose that should be prescribed and that prescribed in the real world include erroneous prescription, an overstated haemorrhagic risk perception, and the presence of frail and complex patients in clinical practice who were not included in pivotal trials, which makes it difficult to apply study results to the real world. For these reasons, we summarize DOAC indications and contraindications. We also suggest the appropriate use of DOACs in common clinical scenarios, in accordance with what international guidelines and national and international health regulatory bodies recommend.

ANMCO statement on the use of sodium-glucose cotransporter 2 inhibitors in patients with heart failure: a practical guide for a streamlined implementation.

Sodium-glucose cotransporter 2 (SGLT2) inhibitors, dapagliflozin, and empagliflozin, first developed as glucose-lowering agents for the treatment of Type 2 diabetes, have been demonstrated to improve prognosis in patients with heart failure and reduced ejection fraction (HFrEF) regardless of the presence of diabetes. Since these drugs have only recently been included among the four pillars of HFrEF treatment, cardiologists are still unfamiliar with their use in this setting. This article provides an up-to-date practical guide for the initiation and monitoring of patients treated with SGLT2 inhibitors.

ANMCO position paper on antithrombotic treatment of patients with atrial fibrillation undergoing intracoronary stenting and/or acute coronary syndromes.

Patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) with or without acute coronary syndromes (ACS) represent a subgroup with a challenging pharmacological management. Indeed, if on the one hand, antithrombotic therapy should reduce the risk related to recurrent ischaemic events and/or stent thrombosis; on the other hand, care must be taken to avoid major bleeding events. In recent years, several trials, which overall included more than 12 000 patients, have been conducted demonstrating the safety of different therapeutic combinations of oral antiplatelet and anticoagulant agents. In the present ANMCO position paper, we propose a decision-making algorithm on antithrombotic strategies based on scientific evidence and expert consensus to be adopted in the periprocedural phase, at the time of hospital discharge, and in the long-term follow-up of patients with AF undergoing PCI with/without ACS.

Occurrence of persistent atrial fibrillation during pacing for sinus node disease: The influence of His bundle pacing versus managed ventricular pacing.

INTRODUCTION: In patients with sinus node disease (SND), the dual-chamber pacemaker (PM) is programmed in DDDR mode with an algorithm to avoid unnecessary right ventricular (RV) pacing. This pacing mode may prolong PR interval with consequently atrioventricular (AV) asynchrony which is associated with a higher risk of atrial fibrillation (AF). We evaluate whether preserving AV synchrony by setting a fixed AV delay during physiological RV pacing, that is, His bundle pacing (HBP), could reduce the risk of AF occurrence in comparison with a standard pacing mode with an algorithm to avoid unnecessary RV pacing (DDD-VPA). METHODS AND RESULTS: We collected retrospective data from 313 consecutive patients who had undergone PM for SND. The first occurrence of persistent AF (>7 consecutive days) as a function of the pacing mode was evaluated. HBP and DDD-VPA were implemented in 82 and 231 patients, respectively. Persistent AF occurred in 128 (40.9%) patients over a median follow-up of 70 months (67-105). The DDD-VPA pacing mode was significantly correlated with the occurrence of persistent AF only when the basal PR was long (>180 ms). The risk of persistent AF was significantly lower in patients on HBP than in those on DDD-VPA, adjusted HR = .57 (95% CI, .36- .89, p=.014). Other independent predictors of persistent AF occurrence were: A history of AF (HR = 3.91; 95% CI, 2.48-6.19, p = .001), age, and long PR interval (HR = 2.98; 95% CI, 2.00-4.43, p=.001). CONCLUSION: In SND patients and long basal PR interval, the HBP may reduce the risk of persistent AF in comparison with the DDD-VPA.

Risk of dementia in patients with atrial fibrillation: Short versus long follow-up. A systematic review and meta-analysis.

BACKGROUND: No previous meta-analyses have compared the risk of dementia, due to an underlying atrial fibrillation (AF), in the short-term versus the long-term period. AIM: To perform an update meta-analysis of studies examining the association between AF and dementia and the relative impact of follow-up period. METHODS: Data were obtained searching MEDLINE and Scopus for all investigations published between 1 January 2000 and March 1, 2021 reporting the risk of dementia in AF patients. The following MeSH terms were used for the search: "Atrial Fibrillation" AND "Dementia" OR "Alzheimer's disease". From each study, the adjusted hazard ratio (aHR) with the related 95% confidence interval (CI) was pooled using a random effect model. RESULTS: The analysis was carried out on 18 studies involving 3.559.349 subjects, of which 902.741 (25.3%) developed dementia during follow-up. A random effect model revealed an aHR of 1.40 (95% CI: 1.27-1.54, p < 0.0001; I2  = 93.5%) for dementia in subjects with AF. Stratifying the studies according to follow-up duration, those having a follow-up ≥10 years showed an aHR for dementia of 1.37 (95% CI: 1.21-1.55, p < 0.0001, I2  = 96.6%), while those with a follow-up duration <10 years has a slightly higher aHR for dementia (HR: 1.59, 95%CI: 1.51-1.67, p < 0.0001, I2  = 49%). Nine studies showed that the aHR for Alzheimer's disease (AD) in AF patients was 1.30 (95%CI: 1.12-1.51, p < 0.0001, I2  = 87.6%). CONCLUSIONS: Evidence suggests that patients with AF have an increased risk of developing dementia and AD. The risk of dementia was slightly higher when the follow-up was shorter than 10 years.

Metabolic syndrome and the risk of late onset Alzheimer's disease: An updated review and meta-analysis.

AIMS: This study aims to provide an updated systematic review and meta-analysis on the risk of Alzheimer's disease (AD) in patients with metabolic syndrome (MetS) and to analyze the contribution of each MetS component on AD onset. DATA SYNTHESIS: The study was performed according to the PRISMA guideline. Data were obtained searching MEDLINE, Scopus, Web of Science, and EMBASE for studies published between January 1, 2010 and July 30, 2020, evaluating the association between MetS and AD risk. A total of 255 articles were retrieved and 6 investigations (4 prospective and 2 retrospective) met the inclusion criteria. Overall, 9.788.021 patients with a mean follow-up of 4.5 years were analyzed. The pooled analysis revealed a slight increased risk of AD in MetS (hazard ratio, HR: 1.10, 95% and confidence interval, CI: 1.05-1.15). Egger's test indicated the absence of publication bias (t = 2.095 and p = 0.104). However, while analysis based on prospective studies failed to show a significant association between MetS and AD (HR: 0.80 and 95% CI: 0.61-1.05), analysis based on retrospective studies demonstrated a significant, slight increased risk (HR:1.11 and 95% CI: 1.08-1.66). With regard to MetS components, the risk was: arterial hypertension, HR: 1.05 (95% CI: 1.04-10.6); hyperglycemia/diabetes, HR: 1.19 (95% CI: 1.18-1.99); low high-density lipoprotein cholesterol (HDL-C), HR: 1.07 (95% CI: 1.06-1.07); hypertriglyceridemia, HR: 1.06 (95% CI: 1.05-1.06); and abdominal obesity, HR: 0.84 (95% CI: 0.74-0.95). CONCLUSIONS: We found a significant association between MetS and AD, mainly driven by large retrospective studies. Our data also support the association of single MetS components with AD incidence, while increased waist circumference seems to have a "protective role" probably due to reverse causality.

Relationship between echocardiographic tricuspid annular plane systolic excursion and mortality in COVID-19 patients: A Meta-analysis.

BACKGROUND: The evaluation of the tricuspid annular plane systolic excursion (TAPSE) is recommended to assess the right ventricular (RV) systolic function. We performed an updated meta-analysis of the association between TAPSE and short-term mortality in COVID-19 patients. METHODS: MEDLINE and Scopus databases were searched to locate all the articles published up to May 1, 2021, reporting data on TAPSE among COVID-19 survivors and non-survivors. The difference of TAPSE between the two groups was expressed as mean difference (MD) with the corresponding 95% confidence interval (CI) using the Mantel-Haenszel random effects model. Both Q value and I2 statistics were used to assess heterogeneity across studies. Sensitivity analysis, meta-regression, and evaluation of bias were performed. RESULTS: Twelve studies, enrolling 1272 COVID-19 patients (778 males, mean age 69.3 years), met the inclusion criteria and were included in the final analysis. Non-survivors had a lower TAPSE compared to survivors (MD =  -3.089 mm, 95% CI =  -4.087 to -2.091, p < 0.0001, I2  = 79.0%). Both the visual inspection of the funnel plot and the Egger's tests (t = 1.195, p = 0.259) revealed no evidence of publication bias. Sensitivity analysis confirmed yielded results. Meta-regression analysis evidenced that the difference in TAPSE between the two groups was only influenced by pre-existing chronic obstructive pulmonary disease (COPD, p = 0.02). CONCLUSION: COVID-19 non-survivors have a lower TAPSE when compared to survivors, especially in COPD subjects. Current data suggest that the TAPSE assessment may provide useful information regarding the short-term prognosis of COVID-19 patients during the infection.

ANMCO POSITION PAPER: The reorganization of cardiology in times of the SARS-CoV-2 pandemic.

The COVID-19 pandemic represents an unprecedented event that has brought deep changes in hospital facilities with reshaping of the health system organization, revealing inadequacies of current hospital and local health systems. When the COVID-19 emergency will end, further evaluation of the national health system, new organization of acute wards, and a further evolution of the entire health system will be needed to improve care during the chronic phase of disease. Therefore, new standards for healthcare personnel, more efficient organization of hospital facilities for patients with acute illnesses, improvement of technological approaches, and better integration between hospital and territorial services should be pursued. With experience derived from the COVID-19 pandemic,new models, paradigms, interventional approaches, values and priorities should be suggested and implemented.

ANMCO POSITION PAPER: Timing of coronary angiography in non-ST-segment elevation acute coronary syndromes.

The European Society of Cardiology guidelines on non-ST-elevation acute coronary syndromes suggest different temporal strategies for the angiographic study depending on the risk profile. The scientific evidence underlying the guideline recommendations and the critical issues currently existing in Italy, that often do not allow either an extended strategy of revascularization within 24 h or the application of the principle of the same day transfer from a spoke to a hub centre, are analysed. The position paper focuses, in particular, on the subgroup of patients with a defined diagnosis of non-ST-elevation myocardial infarction by proposing a timing of coronary angiography/revascularization that takes into account the available scientific evidence and the organizational possibilities of a considerable part of national cardiology services.

ANMCO POSITION PAPER: Role of intra-aortic balloon pump in patients with acute advanced heart failure and cardiogenic shock.

The treatment of patients with advanced acute heart failure is still challenging. Intra-aortic balloon pump (IABP) has widely been used in the management of patients with cardiogenic shock. However, according to international guidelines, its routinary use in patients with cardiogenic shock is not recommended. This recommendation is derived from the results of the IABP-SHOCK II trial, which demonstrated that IABP does not reduce all-cause mortality in patients with acute myocardial infarction and cardiogenic shock. The present position paper, released by the Italian Association of Hospital Cardiologists, reviews the available data derived from clinical studies. It also provides practical recommendations for the optimal use of IABP in the treatment of cardiogenic shock and advanced acute heart failure.

Secundum atrial septal defects transcatheter closure versus surgery in adulthood: a 2000-2020 systematic review and meta-analysis of intrahospital outcomes.

INTRODUCTION: Technologically, advances in both transcatheter and surgical techniques have been continuing in the past 20 years, but an updated comprehensive comparison in device-based versus surgery in adults in terms of incidence of in-hospital mortality, perioperative stroke, and atrial fibrillation onset is still lacking. We investigate the performance of transcatheter device-based closure compared to surgical techniques by a systematic review and meta-analysis of the last 20 years literature data. MATERIAL AND METHODS: The analysis was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Literature search was performed based on Cochrane Library, Embase, PubMed, and Google Scholar to locate articles published between January 2000 and October 2020, regarding the comparison between short-term outcome and post-procedural complications of atrial septal defect patients receiving transcatheter or surgical closure. The primary outcome was the comparison of in-hospital mortality from all causes between patients treated with transcatheter closure or cardiac. Secondary outcomes were the onset of post-procedural atrial fibrillation or perioperative stroke. RESULTS: A total of 2360 patients were included of which 1393 [mean age 47.6 years, 952 females (68.3%)] and 967 [mean age 40.3 years, 693 females (71.6%)] received a transcatheter device-based and surgery closure, respectively. In-hospital mortality [OR 0.16 (95% CI (0.66-0.44)), p = 0.0003, I2 = 0%], perioperative stroke [OR 0.51 (95% CI (0.31-0.84)), p = 0.003, I2 = 79%], and post-procedural atrial fibrillation [OR 0.14 (95% CI (0.03-0.61)), p = 0.009, I2 = 0%] significantly favoured transcatheter device-based closure. CONCLUSION: Transcatheter atrial septal defect closure resulted safer in terms of in-hospital mortality, perioperative stroke, and post-procedural atrial fibrillation compared to traditional surgery.

Electrogram-only guided approach to His bundle pacing with minimal fluoroscopy: A single-center experience.

INTRODUCTION: His bundle pacing (HBP) is the most physiological pacing. The standard technique based on fluoroscopic approach might be challenging and fluoro consuming. Targeting the His guided exclusively by the electrical signals could enable a precise lead implant, thus reducing fluoroscopy time (FT) and X-ray dose, desirable both for patients and operators. The aim of the study is to evaluate the feasibility, efficacy, and safety both acutely and at 30 days of the electrogram (EGM)-guided HBP with minimal or no fluoroscopy. METHODS AND RESULTS: Between October and December 2018, 41 consecutive patients underwent EGM-guided HBP. Successful HBP was obtained in 39 (95%) patients, (30 males, 78 ± 10 years). Selective HBP (S-HBP) was achieved in 23 (59%), nonselective HBP (NS-HBP) in 16 (41%) patients. The final HBP lead position was reached in 31 (79.4%) patients without fluoroscopy, only guided by electrical signals. In eight patients a minimal fluoroscopy (mean, 8 seconds) has been required. The sheath's cutting and the slack of the lead were routinely performed under fluoroscopy. No difference was observed in FT for HBP lead placement in S-HBP and NS-HBP (mean, 8.1 ± 25 vs 7.5 ± 20 seconds, P = .8; median value 0 vs 0 seconds). No differences were observed in FT for the entire procedure, total dose area product and total procedural time in S-HBP and NS-HBP. Lead dislodgement occurred in one (2.6%) patient 1 day after the procedure. CONCLUSIONS: HBP could be performed safely and efficiently using the EGMs, with minimal or no fluoroscopy. Fluoroscopy was required during sheath removal and atrial lead placement.

Left atrial size measured on CT pulmonary angiography: another parameter of pulmonary embolism severity? A systematic review.

We systematically review the potential role of left atrial (LA) size, evaluated at computed tomography angiography (CTA) in patients with acute pulmonary embolism (PE), as a new parameter of PE severity. A literature search based on PubMed (MEDLINE), Scopus, Cochrane library and Google Scholar databases was performed to locate previous published investigations reporting data on the severity of acute PE based on the evaluation of LA size (either volume, diameter or area). Six studies, corresponding to a total of 990 patients, published between 2012 and 2019 were included into the analysis. The severity of acute PE, in terms of hemodynamic impairment, increases with the reduction of the LA volume and a significant negative correlation was observed between the pulmonary artery obstruction index (PAOI) and the LA area. Similarly, the longest left-to-right as well as the anteroposterior diameters of the LA had a significant positive correlation with the PAOI index for both the measurement. The LA volume significantly decreased with the increasing of the PAOI index. Moreover, a lower LA volume was observed in those subjects with a saddle PE appearing as the best single parameter able to discriminate between patients having or not a saddle acute PE. Intriguingly, PE patients died within 30 days from the acute event had a significant small LA volume compared to survivors. Data obtained from the current medical literature seem to suggest that the evaluation of LA size evaluation could be a new parameter of PE severity. Further and larger prospective studies are needed to confirm preliminary findings.

Seizures as the first clinical manifestation of acute pulmonary embolism: an underestimate issue in neurocritical care.

BACKGROUND: The aim of the present review is to analyze the clinical characteristics of patients with acute pulmonary embolism (PE) which seizures were the first clinical manifestation of the disease. METHODS: After screening 258 articles in PubMed, Scopus, Cochrane Library, and Google Scholar databases, we identified 16 case reports meeting the inclusion criteria. RESULTS: The mean age of the population was 48.4 ± 19.8 years (9 males and 7 females). About three of four patients (68.7%) were hemodynamically stable at admission, having a systolic blood pressure > 90 mmHg. Intriguingly, the doubt of acute PE was based on clinical suspicion or on instrumental findings in 62.5% and 18.7% of patients, respectively. In 3 subjects (18.7%), the acute cardiovascular disease was not suspected. Half of patients had an unremarkable previous medical history while neurological comorbidities were present in 4 patients (25.0%). During seizures, a transient loss of consciousness (TLOC) was reported in 6 cases. Seizures were retrospectively classified according to the 2017 ILAE classification, whenever possible. A focal and generalized onset was reported in 37.5% and 50% of cases, respectively, in 12.5% of patient's data that were insufficient to classify the events. The mean number of seizure episodes in the population enrolled was 2.0 ± 1.1. Mortality rate was 54.5% but one investigation did not report the patient's outcome. CONCLUSIONS: The relationship between seizures and acute PE is probably underrecognized. Identifying patients that have a high probability of acute PE is fundamental to avoid any treatment delay and ameliorate their outcomes.

Computational fluid dynamic-derived wall shear stress of non-significant left main bifurcation disease may predict acute vessel thrombosis at 3-year follow-up.

Wall shear stress (WSS) plays a pivotal role on plaque progression in coronary artery disease. We assess the prognostic role of baseline mean WSS in developing a bifurcation-located myocardial infarction (B-MI) over the following 3 years in angiographically non-significant LM bifurcation disease. For this purpose, we retrospectively reviewed the procedural and medical records of consecutive patients evaluated in our center from 1st January 2014 to 1st January 2019 who had a non-significant LM bifurcation disease as evaluated at coronary computed tomography angiography (CCTA) and confirmed by coronary angiography. Each bifurcation model was reconstructed on the patient-specific geometries derived from the CCTA. The population was divided into two groups: patients with (n = 12) and without B-MI (n = 20) over the following 3 years. Both the mean WSSprox of each branch and the WSSentire_lesion of each vessel, adjusted for the respective mean lesions lengths and 3-dimensional percentage of stenosis (DS%), resulted in independent predictors of 3-year B-MI. Multivariate Cox-regression analysis confirmed that a baseline mean WSSentire_model ≥ 5.05 Pa (HR 1.98, 95% CI 1.83-2.10, p = 0.001) was a predictor of 3-year B-MI independently from the entire mean lesions lengths (HR 1.56. 95% CI 1.43.1.68, p = 0.002) and DS% (HR 1.26, 95% CI 1.18-1.37, p = 0.03). In conclusion, in patients with angiographically non-significant LM bifurcation disease, both the mean WSSprox of each branch and WSSentire_lesion of each stenotic vessel predicted the occurrence of B-MI over the following 3 years. Moreover, the WSSentire_bifurcation ≥ 5.05 Pa seems to be a predictor of 3-year B-MI independently from the DS% and lesions lengths.
