Abstract

Background
Infants born small for gestational age (SGA) or following fetal growth restriction (FGR) have an increased risk of neonatal mortality as well as cardiovascular disease later in life. Prenatal electrocardiograms (ECGs) in fetuses with FGR exhibit QT prolongation. However, neonatal alterations in the conduction system in infants born SGA or with FGR has not previously been assessed in a large cohort of infants.

Purpose
To investigate potential variations in electrocardiographic parameters between infants born SGA or diagnosed with FGR, in comparison to infants born appropriate for gestational age (AGA).

Methods
This study was based on data from a population-based cohort study of infants (n&gt;25,000) with prenatal inclusion and postnatal cardiac examination including eight-lead ECG between 2016-2018. We conducted a multiple linear regression analysis to compare ECG parameters among infants with FGR (birthweight &lt;3rd percentile, n=544) and SGA (birthweight ≥3rd and &lt;10th percentile, n=1,384) to infants born AGA (birthweight ≥10th percentile and &lt;90th percentile, n=14,076). Parameters of interest included: heart rate (HR), uncorrected and corrected (Bazzet and Fridericia) QT intervals, QRS duration, PR interval, QRS axis, maximum amplitudes of the R- and S-waves in V1 and V6. All analyses were adjusted for infant sex, gestational age at birth, and weight, length, and age at ECG examination.

Results
Infants born SGA or with FGR had higher HR and consequently shorter uncorrected QT intervals compared with infants born AGA (Table 1). Infants with FGR had significantly shorter corrected (Fridericias) QT intervals. Infants born SGA had smaller amplitudes of both the R- and S-wave in V6, and significantly larger amplitude of the S-wave in V1, compared with infants born AGA (Table 1).

Conclusion
ECGs from infants born SGA and infants with FGR differed from infants born AGA, including higher HRs and shorter uncorrected QT-intervals even after adjustments for infant size and age at the examination. Furthermore, we saw infants born SGA had reduced amplitudes of the S and R wave in the lateral lead (V6), and an increased amplitude of the S-wave in V1, compared with infants born AGA. Follow-up examinations of these infants could determine whether these alterations persist beyond the neonatal period, and to fully understand their implications of the cardiac function later in life.

Abstract

Background
Although the incidence of acute myocardial infarction has been declining over the past decade, the etiology of this trend is unknown. One possible explanation could be changes in coronary plaque phenotype.

Purpose
The aim of this study was to investigate the changes in plaque characteristics over the last 10 years.

Methods
Patients who presented with acute coronary syndrome and underwent preintervention optical coherence tomography (OCT) imaging from 2008 to 2018 were included. Patients were divided into 4 periods: (P1) 2008-2010, (P2) 2011-2013, (P3) 2014-2015, and (P4) 2016-2018. Plaque characteristics at culprit lesion in each period were compared.

Results
Among 1144 patients, 594 (51.9%) presented with ST-segment–elevation myocardial infarction (STEMI). The prevalence of thin-cap fibroatheroma decreased from P1 to P4 in both STEMI group (57.4% to 24.6%, P&lt;0.001) and non-ST-segment elevation acute coronary syndrome (NSTE-ACS) group (40.4% to 17.0%, P&lt;0.001) (Figure).

Conclusions
The prevalence of OCT features of plaque vulnerability has decreased over the past 10 years. A decrease in plaque vulnerability may explain the favorable trend in cardiovascular events.Prevalence of thin-cap fibroatheroma

Abstract

Introduction
The infection caused by Zika virus during pregnancy leads to congenital Zika syndrome (CZS). In a previous study of our group, we found that the heart is smaller in children with CZS, with few functional alterations. Left atrial strain imaging enables quantitative assessment of left atrial function, and recently its application has also shown promise in the pediatric population.

Purpose
To evaluate left atrial function in children affected by CZS, using echocardiogram and speckle tracking imaging technique.

Methods
This observational study was conducted with children with CZS using a two-dimensional speckle tracking technique to measure left atrial reservoir strain (LAS-r), conduit strain (LAS-cd), and contraction strain (LAS-ct). Also, to investigate the relationship between LAS-r and systolic excursion of the septum and lateral mitral annular plane (MAPSE), left atrial volume index and E/e’ ratio.

Results
A total of 52 patients were included, the median age of the studied population was 5 years (3 to 6), 59.6% male, and the body surface area was 0.66 [0.51, 0.90]. In the echocardiographic evaluation the left atrium volume index (ml/m²) was 13.15 [6.80, 18.00], considered smaller by the reference value. Also, the LAS-r (%) was 40.99 [24-70.5], LAS-cd (%) was 30,94 [32.5-52.5], LAS-cd (%) was 10,91 [5.2-24], values considered normal by the literature. Lateral MAPSE (cm) was 1.25 [0.81, 1.86] and septal MAPSE (cm) was 0.98 [0.78, 1.66] and E/e' ratio was 7.52 [4.57, 10.78]. A positive linear correlation was found between LAS-r and lateral MAPSE (r = 0.51, P = 0.019).

Conclusion
This original study with children with CZS shows that despite reduced atrial volume, the left atrial function remains normal, and correlates with left ventricular function evaluated by MAPSE. Further studies are needed to prospectively analyze the follow-up of left atrial morphology and function in this population.

Abstract

Background/Introduction
In the POISE-3 trial involving patients undergoing noncardiac surgery, tranexamic acid (TXA) reduced the incidence of the composite outcome of life-threatening bleeding, major bleeding, or bleeding into a critical organ at 30 days. Bleeding is a major issue in vascular surgery. However, TXA use may be limited due to concerns about its safety in this high-risk population. With 1,399 participants in POISE-3 undergoing vascular surgery, this is the largest trial assessing TXA's efficacy in this population.

Purpose
In this post hoc subgroup analysis, we aimed to investigate the interaction between surgery type (vascular/non-vascular) and the effects of TXA vs placebo on bleeding and cardiovascular (CV) safety outcomes in the POISE-3 population.
Methods:
Eligible patients were ≥45 years, undergoing inpatient noncardiac surgery, and at risk for bleeding and CV complications. Patients were randomised (1:1) to TXA 1 gm IV bolus at start and end of surgery (total 2 gm) or placebo. We used Cox proportional hazards models incorporating tests for interaction to analyse time to the first occurrence of the composite bleeding outcome, and the CV safety outcome (composite of myocardial injury after noncardiac surgery, non-hemorrhagic stroke, peripheral arterial thrombosis, or symptomatic proximal venous thromboembolism) at 30 days. Estimates of hazard ratios (HR) with 95% confidence intervals (CI) were calculated for each subgroup with the interaction P value.

Results
9,468 of 9535 (99.3%) POISE-3 patients are included in this analysis; 1399 of whom underwent vascular surgery (699 TXA, 700 placebo). Majority (89.8%) of the vascular surgeries were aorto-iliac, peripheral vascular and extracranial surgeries. In the vascular surgery group, 12.6% of patients receiving TXA experienced the composite bleeding outcome versus 14.7% with placebo (HR 0.85, 95% CI 0.64-1.13). For non-vascular surgery patients, these rates were 8.6% with TXA and 11.3% with placebo (HR 0.74, 95% CI 0.65-0.86), with an interaction P value of 0.42. In vascular surgery patients, the CV safety outcome occurred in 20.2% with TXA versus 18.1% with placebo (HR 1.12, 95% CI 0.88-1.42). In the non-vascular surgery group, both TXA and placebo arms showed a 13.1% incidence rate (HR 1.00, 95% CI 0.89-1.13), with an interaction P value of 0.43.

Conclusion
In vascular surgery patients, there were higher rates of bleeding and cardiovascular events compared to those undergoing non-vascular surgeries; however, there was no significant interaction between the effects of TXA and the type of surgery. The overall POISE-3 trial provides the best estimate of effect with TXA for all patients including those undergoing vascular surgery. The main limitation is that this subgroup analysis was not pre-specified.

Abstract

Background
Predicting cardiac complications after non-cardiac surgery is challenging.

Purpose
to determine the predictive accuracy of N-Terminal Pro–B-Type Natriuretic Peptide (NT-proBNP) and, to assess the utility of existing NT-proBNP cutoffs of the 2021 ESC Guidelines for the diagnosis of acute and chronic heart failure for prediction of postoperative acute heart failure (pAHF), perioperative myocardial infarction/injury (PMI) and mortality following non-cardiac surgery.

Methods
we prospectively determined preoperative NT-proBNP concentrations in consecutive patients at high cardiac risk undergoing inpatient non-cardiac surgery. Uni- and multivariable regression models were constructed to test the association between NT-proBNP concentrations and the outcomes (pAHF, PMI, 30-day and one-year mortality), using NT-proBNP as a continuous variable. We further stratified NT-proBNP into 5 categories according to guidelines (&lt;125 pg/ml, 125 to 299pg/ml, 300 to 900 pg/ml, 901 to 1800pg/ml and &gt;1800 pg/ml). Receiver operating characteristic curves were constructed to determine the predictive value of NT-proBNP.

Results
Among the 2,334 cases included, pAHF occurred in 83 (3.6%), PMI in 381 (17%), 45 (2.5%) patients died within 30 days and 179 (10%) within one year. After adjusting for confounders, NT-proBNP concentrations were independent predictors of pAHF (adjusted hazard ratio [aHR] 1.8 [95%CI, 1.5-2.1], p&lt;0.001), PMI (aHR 1.3 [95%CI, 1.2-1.4],p&lt;0.001) and 30 day/one year mortality (aHR 1.6[95%CI, 1.3-2.0], p&lt;0.001)/aHR 1.5 [95%CI 1.4-1.7], p&lt;0.001). By quintiles, higher the NT-proBNP levels were strongly associated with adverse outcome (Figure). Accuracy of preoperative NT-proBNP for prediction of pAHF was excellent (area under the curve [AUC] 0.825) and better than accuracy of the Revised Cardiac Risk Index score (AUC 0.692, p&lt;0.001), whereas accuracy of NT-proBNP for prediction of PMI (AUC 0.654) and mortality (AUC 0.787) was only moderate.

Conclusion
NT-proBNP concentrations are independent predictors of pAHF, PMI and short and long-term mortality following non-cardiac surgery. Stratifying NT-proBNP concentrations using current recommended cut-offs could help to further determine the magnitude of the risk, mainly of pAHF.

Abstract

Background
malnutrition is a marker of unfavorable prognosis in different medical conditions, however, the association between new objective immunonutritional indexes and outcomes for patients with infective endocarditis (IE) is not fully studied.

Purpose
the aim of this study was to assess the role of the Controlling Nutritional Status (CONUT) Score in the characterization of patients with IE and its association with prognostic outcomes.

Methods
a total of 184 cases of confirmed IE were consecutively collected and followed during one year after diagnosis in two tertiary hospitals. CONUT score was calculated using serum albumin, total cholesterol and lymphocyte count [(range 0-12), the higher, the worse] at diagnosis, and patients were categorised as CONUT-high (&gt;=6, n=98), and CONUT-low (&lt;6, n=86) based on the sample median value.

Results
mean age was 70 [SD 15] years, 64% were men and community-acquired infections were 69%. Median score value was 6 (4). As shown in Table 1 and 2, diabetes and frailty were more prevalent in CONUT-high group, who showed a worse profile of nutritional biomarkers. Overall, the most frequent pathogen was S. viridans (n=43). By groups, S. aureus was predominantly isolated in CONUT-high (20 vs 8%; p 0.02), and non-viridans streptococci in CONUT-low (9 vs 2%, p 0.03). Regarding infection site, IE of aortic bioprostheses was more common in CONUT-high, whereas mechanical aortic valves and mitral bioprostheses were more frequently involved in CONUT-low. Larger vegetations [14 (11) vs 11 (7) mm, p 0.02], and more periannular abscesses (25 vs 13%, p 0.04) were detected in CONUT-high, who presented more acute kidney injury and septic shock during hospitalization. Despite higher predicted surgical risk in CONUT-high, neither the proportion of patients who underwent surgery nor in-hospital mortality, differed between groups. When analyzing according to the therapeutic approach, only among those medically managed patients without surgical indication, in-hospital mortality was higher in CONUT-high. At 1-year follow-up, rehospitalization rate tended to be lower in those with a better nutritional status (35% vs 51%, p 0.07).

Conclusions
in patients with IE and a high CONUT score, diabetes and frailty were more prevalent. In addition, virulent pathogens, larger vegetations and periannular complications were more frequently reported. Although surgery performance and in-hospital mortality did not differ between groups, a worse nutritional status was associated with a higher rate of clinical complications and higher mortality among patients with conservative management who did not meet surgical criteria.

Abstract

Background
infective endocarditis (IE) remains a severe condition associated with a remarkably high mortality in certain groups of patients

Purpose
the aim of this study was to compare both the clinical management and short and mid-term prognosis of patients with IE according to their frailty status.
Methods: a total of 200 cases of confirmed IE were consecutively collected in two tertiary hospitals between September 2016 and February 2021, and prospectively followed during one year after diagnosis. Patients were categorised according to the 5-item FRAIL scale as: Group A (n=48), for scores &gt;2, and Group B (n=152), for scores &lt;=2.

Results
mean age was 70 [SD 15] years, 64% were men and community-acquired infections were 69%. Baseline and clinical data are shown in Table 1. Enterococci were more frequent in Group A, but no significant differences were found regarding infection site, presence of vegetations or periannular complications, time to diagnosis or length of stay. During hospitalization, acute heart failure, delirium and bronchoaspiration were more common among frail patients. Unlike 18F-FDG PET/CT, which was more frequently done in Group B (34 vs 17%, p 0.03), transesophageal echocardiography was similarly performed between groups (92 vs 97%, p 0.08). Less frail patients underwent cardiac surgery (42 vs 68%, p 0.001), with a larger proportion of inoperable patients despite meeting surgical criteria (29 vs 12%, p 0.002). In-hospital mortality was higher in Group A, both overall and by therapeutic strategies, except in those inoperable patients with surgical indication but treated conservatively, where mortality did not differ between groups. Among survivors who completed follow-up (n=144), although recurrence rates were similar, readmission (75 vs 35%, p &lt;0.001) and all-cause mortality rates (36 vs 5%, p &lt;0.001) in Group A exceeded those from Group B. Predictors of in-hospital and 1-year mortality were assessed by logistic regression (Fig. 1), confirming the independent prognostic role of baseline FRAIL score in patients with IE [OR 1.5 (1.2-2.3) and 2.0 (1.5-2.6), respectively, for every additional scale point].

Conclusions
frail patients with IE were older, more prone to enterococcal infections and in-hospital complications and had greater comorbidity burden. Both PET/CT and cardiac surgery were less performed in this group, which was characterized by a higher predicted surgical risk, as well as a worse short and mid-term prognosis.

Abstract

Introduction
Chronic kidney disease (CKD) and frailty are often present in older patients with heart failure (HF). Our aim was to evaluate the impact of CKD and frailty in one-year mortality in a cohort of older (≥75 years) outpatients with HF.

Methods
Our data come from the FRAGIC study ("Study of the impact of frailty and other geriatric syndromes on the clinical management and prognosis of older outpatients with heart failure"), a multicenter prospective registry conducted in 16 cardiology services in Spain which included ≥75 years outpatients with HF.

Results
We included 499 patients, mean age 81.4 ± 4.3 years, 38% women. Mean estimated glomerular filtration rate (eGFR) was 52.1±17.5 ml/min/1.72 m2. Patients were classified in three groups: eGFR ≥60 ml/min/1.72m2 (normal: 182 patients, 36%), eGFR 30-59 ml/min/1.72m2 (moderately impaired: 261 patients, 52.7%), and eGFR &lt; 30 ml/min/1.72m2 (severely impaired: 56 patients, 11.3%). Patients with severe renal dysfunction were older, more often female, and presented a worse clinical profile, with higher comorbidity burden and frailty. Baseline variables according to eGFR group are depicted in Table 1. After a median follow up of 371 days, 58 patients (11.6%) died. One year mortality was higher in patients with worse renal function (8.8%, 11% and 21% according to normal, moderate and severe renal dysfunction respectively, p=0.036) and in frail patients (Figure 1). In multivariate analysis, frailty, but not severe renal dysfunction, was associated with one year mortality (frailty HR 2.05 95%CI 1.11-3.78 p 0.021, eGFR &lt; 30 and 30-60 ml/min/1.72m2 HR 1.39 95%CI 0.62-3.09 p0.424 and 1.09 95%CI 0.58-2.09 p0.793 respectively).

Conclusions
Most HF patients ≥75 years have renal dysfunction. The association between renal function and clinical outcomes is different according to frailty status. CKD is related to worse prognosis only in non-frail patientsCumulative incidence of 1-year mortalityTable 1.Baseline characteristics

Abstract

Background
Guidelines recommend ticagrelor over clopidogrel in patients with AMI, irrespective of their age. The PLATO trial, which showed lower mortality with ticagrelor, included only few very elderly patients.

Purpose
To analyze one- and 5-year outcomes according to use of ticagrelor vs clopidogrel as first P2Y12-inhibitor at the acute stage of AMI, in real-life conditions in patients aged ≥80 years.

Methods
FAST-MI 2015 included consecutive patients with AMI in 204 centers throughout France. This analysis focused on patients ≥ 80 years of age, in whom the first P2Y12-inhibitor used was either clopidogrel or ticagrelor. Both Cox time-dependent logistic regression and propensity score (PS) matching were used.

Results
Among 5,291 patients, 995 (19%) were aged ≥ 80 years, of whom 721 (72%) met the inclusion criteria. Mean age was 86 ± 4 years for patients receiving clopidogrel and 84±3 for those receiving ticagrelor, 54% and 52% respectively were women, and 37% vs 54% had STEMI.
Using Cox time-dependent regression, the HR (95%CI) for use of ticagrelor vs clopidogrel first was 1.11 (0.75-1.67), P=0.59 for one-year death and 0.61 (0.43-0.86), P=0.004 for death from one to 5 years.
After PS matching, the two cohorts (N=231 each) were well balanced; one-year mortality was similar for the 2 medications, while 5-year survival was higher for those receiving ticagrelor first (Figure).

Conclusion
In this real-world population of elderly patients (mean age 85 years) with AMI, the use of ticagrelor as the first P2Y12-inhibitor was associated with similar survival at one year and improved survival at 5 years, compared with clopidogrel. The diverging one- and 5-year results suggest the possibility of unmeasured confounders. Further research is needed in older patients.Kaplan-Meir curves: survival at 5-years
