Dataset related to the article "Sex effect on efficacy of pulmonary vein cryoablation in patients with atrial fibrillation: data from the multicenter real-world 1STOP project"

This record contains raw data related to the article "Sex effect on efficacy of pulmonary vein cryoablation in patients with atrial fibrillation: data from the multicenter real-world 1STOP project”   ABSTRACT PURPOSE: Pulmonary vein isolation (PVI) using cryoablation (PVI-C) is a widespread therapy for treating symptomatic, recurrent atrial fibrillation (AF). The impacts of sex on efficacy and safety of PVI-C in a real-world clinical practice is lacking. In a multicenter prospective project, we evaluated whether clinical characteristics, procedure parameters, procedural complications, long-term AF recurrence rates, and/or AF-related symptoms differed according to sex in patients treated with PVI-C. METHODS: Data from the study population were collected in the framework of the 1STOP ClinicalService® project, involving 47 Italian cardiology centers. Multivariable statistical analyses were conducted to determine if any baseline clinical characteristics impacted the efficacy of PVI-C. RESULTS: From April 2012, 2125 patients (27% female, 59 ± 11 years, 73% paroxysmal AF, and mean left atrial diameter = 42 ± 8 mm) underwent PVI-C. According to baseline characteristics, women were more likely to be older, with higher clinical risk scores (e.g., CHA2DS2-VASc), and a higher number of tested antiarrhythmic drugs before the index PVI-C procedure. Male and female cohorts showed comparable procedure time (mean =&thinsp;107.7 ± 46.8 min) and a similar incidence of periprocedural complications (4.5% overall), even after adjustment for baseline characteristics (P =&thinsp;0.880). The multivariable analyses demonstrated that the strongest predictor of AF recurrences was sex (0.74; 95% CI 0.58-0.93; P =&thinsp;0.011). After propensity score adjustment, the hazard ratio from a multivariable model, which included age and AF type (persistent) as covariates, was 0.76 (0.60-0.97) (P =&thinsp;0.025). CONCLUSIONS: According to the 1STOP project, in a real-world setting, PVI-C was relatively safe regardless of the patient's sex; however, when considering efficacy of the procedure, female patients had a lower long-term efficacy in comparison to males.

Lag-time in Alzheimer's disease patients: a potential plasmatic oxidative stress marker associated with ApoE4 isoform. Immun Ageing. 2019 Apr 1;16:7. doi: 10.1186/s12979-019-0147-x. PMID: 30984280; PMCID: PMC6444862. This is the astract: In the brain, Oxidative Stress (OS) contribute to structural and functional changes associated with vascular aging, such as endothelial dysfunction, extracellular matrix degradation, resulting in age-related reduced vasodilatation in response to agonists. For this reason, OS is considered a key factor in Alzheimer's Disease (AD) development and recent evidence correlated oxidative stress with vascular lesion in the pathogenesis of AD, but the mechanism still need to be fully clarified. The etiology of AD is still not completely understood and is influenced by several factors including Apolipoprotein E (ApoE) genotype. In particular, the Apo ε4 isoform is considered a risk factor for AD development. This study was aimed to evaluate the possible relationship between three plasmatic OS marker and Apo ε4 carrier status. Plasmatic soluble receptor for advanced glycation end products (sRAGE) levels, plasma antioxidant total defenses (by lag-time method) and plasmatic Reactive Oxygen species (ROS) levels were evaluated in 25 AD patients and in 30 matched controls. ROS were significantly higher while plasma antioxidant total defenses and sRAGE levels were significantly lower in AD patients compared to controls. In AD patients lag-time values show a significant positive linear correlation with sRAGE levels and a (even not significant) negative correlation with ROS levels. Lag-time is significantly lower in ε4 carrier (N = 13) than in ε4 non-carrier (N = 12). Our result confirms the substantial OS in AD. Lag-time levels showed a significant positive correlation with sRAGE levels and a significant association with ε4 carrier status suggesting that plasmatic lag-time evaluation can be considered as a potential useful OS risk marker in AD.

PMID: 31630105; PMCID: PMC6803081.   This is the abstract: Objectives: To provide the first epidemiological lifestyle descriptions of the Italian grown-up/adult congenital heart disease (GUCH/ACHD) population by identifying the determinants of poor perceived health status. Design: Cross-sectional pan-national survey. Setting: Italian GUCH/ACHD patients who were members of the Italian Association of GUCH/ACHD. Primary and secondary outcome measures: To discuss these lifestyle descriptions through an ad hoc developed questionnaire and health perceptions (ie, mental and physical health perception) through a short form health survey (SF-12). Results: 629 patients included; many investigated GUCH/ACHD lifestyles were determined similar to those of the general population - with the exception of the smoking habits, which were lower. The odds of the occurrence of inadequate physical health perceptions increased by more than two times in patients undergoing antiarrhythmic therapies (OR adjusted=2.045; 95% CI=1.201 to 3.479; p=0.008; n=629), more than 1.5 times in patients taking oral anticoagulants (OR adjusted=1.638; 95% CI=1.038 to 2.585; p=0.034; n=629) and roughly 1.7 times in patients treated with antiplatelets (OR adjusted=1.743; 95% CI=1.024 to 2.966; p=0.041; n=629). The odds of the occurrence of inadequate mental health perceptions increased by 1.7% for every year that the patients aged (OR adjusted=1.017; 95% CI=1.002 to 1.032; p=0.025; n=629). Conclusion: Particular attention should be paid to these ageing patients' increasing psychological needs, and additional research is needed to identify associations between their lifestyles and clinical outcomes.

PMID: 31790832.   This is the abstract: Background: Implantable cardioverter-defibrillators (ICDs) are increasingly being used to prevent sudden death in the growing population of adults with congenital heart disease (CHD). However, little is known about their impact on patient-reported outcomes (PROs). Objective: The purpose of this study was to assess and compare PROs in adults with CHD with and without ICDs. Methods: A propensity-based matching weight analysis was conducted to evaluate PROs in an international cross-sectional study of adults with CHD from 15 countries across 5 continents. Results: A total of 3188 patients were included: 107 with ICDs and 3081 weight-matched controls without ICDs. ICD recipients were an average age of 40.1 ± 12.4 years, and >95% had moderate or complex CHD. Defibrillators were implanted for primary and secondary prevention in 38.3% and 61.7%, respectively. Perceived health status, psychological distress, sense of coherence, and health behaviors did not differ significantly among patients with and without ICDs. However, ICD recipients had a more threatening view of their illness (relative % difference 8.56; P = .011). Those with secondary compared to primary prevention indications had a significantly lower quality-of-life score (Linear Analogue Scale 72.0 ± 23.1 vs 79.2 ± 13.0; P = .047). Marked geographic variations were observed. Overall sense of well-being, assessed by a summary score that combines various PROs, was significantly lower in ICD recipients (vs controls) from Switzerland, Argentina, Taiwan, and the United States. Conclusion: In an international cohort of adults with CHD, ICDs were associated with a more threatening illness perception, with a lower quality of life in those with secondary compared to primary prevention indications. However, marked geographic variability in PROs was observed.

Epub 2018 Jul 23. PMID: 30077534.   This is the abstract: Aims: Religion and spirituality can be resources for internal strength and resilience, and may assist with managing life's challenges. Prior studies have been undertaken primarily in countries with high proportions of religious/spiritual people. We investigated (i) whether being religious/spiritual is an independent predictor of patient-reported outcomes (PROs) in a large international sample of adults with congenital heart disease, (ii) whether the individual level of importance of religion/spirituality is an independent predictor for PROs, and (iii) if these relationships are moderated by the degree to which the respective countries are religious or secular. Methods and results: APPROACH-IS was a cross-sectional study, in which 4028 patients from 15 countries were enrolled. Patients completed questionnaires to measure perceived health status; psychological functioning; health behaviors; and quality of life. Religion/spirituality was measured using three questions: Do you consider yourself religious or spiritual?; How important is religion, spirituality, or faith in your life?; and If religious, to what religion do you belong?. The country level of religiosity/secularity was appraised using data from the Gallup Poll 2005-2009. General linear mixed models, adjusting for patient characteristics and country differences were applied. Overall, 49.2% of patients considered themselves to be religious/spiritual. Being religious/spiritual and considering religion/spirituality as important in one's life was positively associated with quality of life, satisfaction with life and health behaviors. However, among patients living in more secular countries, religion/spirituality was negatively associated with physical and mental health. Conclusion: Religiosity/spirituality is an independent predictor for some PROs, but has differential impact across countries. Keywords:;

PMID: 30808198.   This is the abstract: Background: Inter-country variation in patient-reported outcomes of adults with congenital heart disease has been observed. Country-specific characteristics may play a role. A previous study found an association between healthcare system performance and patient-reported outcomes. However, it remains unknown which specific components of the countries' healthcare system performance are of importance for patient-reported outcomes. Aims: The aim of this study was to investigate the relationship between components of healthcare system performance and patient-reported outcomes in a large sample of adults with congenital heart disease. Methods: A total of 1591 adults with congenital heart disease (median age 34 years; 51% men; 32% simple, 48% moderate and 20% complex defects) from eight European countries were included in this cross-sectional study. The following patient-reported outcomes were measured: perceived physical and mental health, psychological distress, health behaviours and quality of life. The Euro Health Consumer Index 2015 and the Euro Heart Index 2016 were used as measures of healthcare system performance. General linear mixed models were conducted, adjusting for patient-specific variables and unmeasured country differences. Results: Health risk behaviours were associated with the Euro Health Consumer Index subdomains about patient rights and information, health outcomes and financing and access to pharmaceuticals. Perceived physical health was associated with the Euro Health Consumer Index subdomain about prevention of chronic diseases. Subscales of the Euro Heart Index were not associated with patient-reported outcomes. Conclusion: Several features of healthcare system performance are associated with perceived physical health and health risk behaviour in adults with congenital heart disease. Before recommendations for policy-makers and clinicians can be conducted, future research ought to investigate the impact of the healthcare system performance on outcomes further.

Erratum in: Eur J Cardiothorac Surg. 2019 Dec 1;56(6):1208. PMID: 31038681.   The abstract: Objectives: Type III aortic arch configuration consistently presents anatomical and biomechanical characteristics which have been associated with an increased risk of type B aortic dissection (TBD). Our aim was to investigate the prevalence of type III arch in patients with TBD and type B intramural haematoma (IMH-B). Methods: A multicentre retrospective analysis was performed on patients with TBD and IMH-B observed between 2002 and 2017. The computed tomographic images were reviewed to identify the type of aortic arch. Exclusion criteria included previous arch surgery, presence of aortic dissection or aneurysm proximal to the left subclavian artery and bovine arches. An ad hoc systematic literature review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines to assess the prevalence of type III arch in non-TBD and non-aneurysmal patients. Results: Two hundred and sixty-one patients with TBD/IMH-B were found to be suitable for the study and were stratified according to aortic arch classification. The ad hoc literature search provided 10 relevant articles, from which a total of 7983 control cases were retrieved. TBD/IMH-B patients were significantly younger than controls [64.3, standard error: 0.74 (62.84-65.76) vs mean pooled age 70.5, standard error: 0.40 (69.71-71.28)]. Patients with TBD/IMH-B presented with a significantly higher prevalence of type III arch [41.0% (107/261) (35.2-47.1)] than controls [16% (1241/7983) (10-22)]. Conclusions: Our data indicate an association between type III arch configuration and the occurrence of TBD/IMH-B. These findings warrant further studies to disclose the potential role of type III arch configuration as an anatomical risk factor for TBD/IMH-B.

Eur J Cardiothorac Surg. 2019 May 1;55(5):990-997. doi: 10.1093/ejcts/ezy409. PMID: 30535119.   This is the abstract: Objectives: Our goal was to confirm whether the Modified Arch Landing Areas Nomenclature (MALAN) for thoracic endovascular aortic repair, in which each landing area is described by indicating both the proximal landing zone (PLZ) and the type of arch (e.g. 0/I), identifies unfavourable landing zones for endograft deployment in diseased aortas. Methods: Preoperative computed tomography angiography scans of 10 patients scheduled for thoracic endovascular aortic repair for aneurysm or penetrating ulcer of the arch and with a potential hostile PLZ were reviewed. Five had proximal deployment planned in MALAN area 3/III and 5, in MALAN area 2/III. The angulation of each PLZ was calculated. Computational fluid dynamics modelling was used to compute magnitude and orientation of pulsatile displacement forces in each PLZ. Normalized values based on PLZ areas (i.e. equivalent surface traction) were calculated. Results were compared to those obtained in healthy controls stratified by the MALAN. Results: Angulation was severe (>60°) in MALAN areas 3/III and 2/III, which was consistent with the findings obtained in healthy controls. Increased magnitude (P = 0.021) and unfavourable orientation (i.e. orthogonal to the longitudinal aortic axis) of equivalent surface traction (P = 0.011) was also found in these areas compared to the adjacent ones, following the same pattern seen in the controls. Adverse events related to proximal endograft performance were reported in 3/10 cases. Conclusions: This study confirms in diseased aortas initial proof-of-concept findings on the predictive value of the MALAN to identify landing areas with a geometric and haemodynamic environment hostile for thoracic endovascular aortic repair. These adverse biomechanical features may entail an increased risk of dismal endograft performance.

PMID: 31292628.   This is the abstract: Aims: The Brugada syndrome (BrS) is an inherited disease associated with an increased risk of sudden cardiac death. Often, the genetic cause remains undetected. Perhaps due at least in part because the NaV1.8 protein is expressed more in both the central and peripheral nervous systems than in the heart, the SCN10A gene is not included in diagnostic arrhythmia/sudden death panels in the vast majority of cardiogenetics centres. Methods and results: Clinical characteristics were assessed in patients harboring either SCN5A or novel SCN10A variants. Genetic testing was performed using Next Generation Sequencing on genomic DNA. Clinical characteristics, including the arrhythmogenic substrate, in BrS patients harboring novel SCN10A variants and SCN5A variants are comparable. Clinical characteristics, including gender, age, personal history of cardiac arrest/syncope, spontaneous BrS electrocardiogram pattern, family history of sudden death, and arrhythmic substrate are not significantly different between probands harboring SCN10A or SCN5A variants. Conclusion: Future studies are warranted to further characterize the role of these specific SCN10A variants.

PMID: 31551801; PMCID: PMC6736624.   This is the abstract: Primary Sjögren's syndrome (pSS) is an autoimmune disease affecting exocrine glands and extra-glandular organs. There are conflicting reports on the presence of autonomic dysfunction in pSS and no data are available on the functional status of sympathetic outflow to the vessels and baroreceptor [baroreflex sensitivity (BRS)] control mechanisms. We investigated the cardiac (cBRS) and sympathetic (sBRS) baroreceptor modulation in both time and frequency domains and the cardiovascular autonomic profile in pSS patients compared to healthy controls. Autonomic symptoms were quantified by the Composite Autonomic Symptom Scale (COMPASS31) three-item questionnaire. The EULAR Sjogren's syndrome patient reported index (ESSPRI) questionnaire evaluated the magnitude of pSS clinical symptoms, i.e., fatigue, pain, and sicca symptoms. Electrocardiogram, beat-by-beat arterial pressure (AP) and respiratory activity were continuously recorded in 17 pSS patients and 16 healthy controls, while supine and during 75° head-up tilt. In seven patients and seven controls, muscle sympathetic nerve activity (MSNA) was measured. Spectrum analysis of RR variability provided markers of cardiac vagal modulation (HFRR nu) and sympatho-vagal balance [low frequency (LF)/high frequency (HF)]. The power of LF (0.1 Hz) oscillations of systolic arterial pressure (SAP) variability (LFSAP) evaluated the vasomotor response to sympathetic stimulation. Compared to controls, pSS patients scored higher in total COMPASS31 (p < 0.0001) and all ESSPRI subdomains (fatigue, p = 0.005; pain, p = 0.0057; dryness, p < 0.0001). Abnormal scialometry (<1.5 ml/15 min) and Schirmer tests (<5 mm/5 min) were found in pSS patients and salivary flow rate was negatively associated with ESSPRI dryness (p = 0.0014). While supine, pSS patients had lower SEQcBRS index of cardiac baroreceptor sensitivity, higher HFRRnu (p = 0.021), lower LF/HF (p = 0.007), and greater MSNA (p = 0.038) than controls. No differences were observed in LFSAP between groups. During orthostatic challenge, although LFSAP increased similarly in both groups, MSNA was greater in pSS patients (p = 0.003). At rest pSS patients showed lower cBR control and greater parasympathetic modulation. Furthermore, greater sympathetic nerve activity was observed in pSS patients while supine and in response to gravitational challenge. We hypothesized that such enhanced sympathetic vasoconstrictor activity might reflect an attempt to maintain blood pressure in a setting of likely reduced vascular responsiveness.

PMID: 31756528.   This is the abstract: Background: The relationship between the typical electrocardiographic pattern and electromechanical abnormalities has never been systematically explored in Brugada syndrome (BrS). Objectives: The aims of this study were to characterize the electromechanical substrate in patients with BrS and to evaluate the relationship between electrical and mechanical abnormalities. Methods: We enrolled 50 consecutive high-risk patients with BrS (mean age 42 ± 7.2 years), with implantable cardioverter-defibrillator implantation for primary or secondary prevention of ventricular tachyarrhythmias (ventricular tachycardia/ventricular fibrillation [VT/VF]), undergoing substrate mapping and ablation. Patients underwent 3-dimensional (3D) echocardiography with 3D wall motion/deformation quantification and electroanatomic mapping before and after ajmaline administration (1 mg/kg in 5 minutes); 3D mechanical changes were compared with 50 age- and sex-matched controls. The effect of substrate ablation on electromechanical abnormalities was also assessed. Results: In all patients, ajmaline administration induced Brugada type 1 pattern, with a significant increase in the electrical substrate (P < .001), particularly in patients with previous spontaneous VT/VF (P = .007). Induction of Brugada pattern was associated with lowering of right ventricular (RV) ejection fraction (P < .001) and worsening of 3D RV mechanical function (P < .001), particularly in the anterior free wall of the RV outflow tract, without changes in controls. RV electrical and mechanical abnormalities were highly correlated (r = 0.728, P < .001). By multivariate analysis, only the area of RV dysfunction was an independent predictor of spontaneous VT/VF (odds ratio 1.480; 95% confidence interval 1.159-1.889; P = .002). Substrate ablation abolished both BrS-electrocardiographic pattern and mechanical abnormalities, despite ajmaline rechallenge. Conclusion: BrS is an electromechanical disease affecting the RV. The typical BrS pattern reflects an extensive RV arrhythmic substrate, driving consistent RV mechanical abnormalities. Substrate ablation abolished both Brugada pattern and mechanical abnormalities.

PMID: 30837178.   This is the abstract: Objective: The objective of this study was to analyze preoperative risk factors affecting long-term survival and the occurrence of stroke in patients older than 80 years undergoing either carotid endarterectomy (CEA) or carotid artery stenting (CAS) for carotid stenosis. Methods: Data of all consecutive patients treated from January 1999 to December 2017 were retrospectively reviewed and outcomes analyzed. Kaplan-Meier analysis was used to estimate long-term survival and the risk of stroke for both groups. Cox proportional hazards analysis was used to assess the relative risk of all-cause mortality and long-term stroke for patients in the presence of selected comorbidities, including preoperative symptoms, coronary artery disease, chronic renal failure, atrial fibrillation (AF), hypertension, diabetes mellitus, and dyslipidemia. A P value <.05 was considered statistically significant. Results: A total of 473 patients older than 80 years (298 men [63%]) underwent either CEA (n = 178) or CAS. At 30 days, one patient died in the CEA group of unrelated causes; no deaths were recorded after CAS (0.6% vs 0%; P = .18). At 5 years, survival was 67.6% ± 4.9% after CEA and 90.2% ± 2.3% after CAS (P < .0001). The main cause of death after CEA and CAS was a neoplasm. Estimated freedom from any stroke at 5 years was 97.3% ± 0.5% after CEA and 93.2% ± 1.2% after CAS (P = .07). The presence of preoperative AF significantly affected long-term mortality after CAS (hazard ratio [HR], 1.56; 95% confidence interval [CI], 1.34-1.98; P = .04) as well as being classified as American Society of Anesthesiologists class 3 at evaluation of the preoperative anesthesiology risk. The presence of preoperative AF was the only factor that significantly affected the occurrence of long-term stroke after both CAS (HR, 2.28; 95% CI, 1.86-5.63; P = .001) and CEA (HR, 3.45; 95% CI, 2.29-8.19; P = .005). Conclusions: Both CEA and CAS showed low 30-day mortality and any-stroke rates in patients older than 80 years. In the long term, survival was significantly better after CAS; however, deaths after CEA and CAS were mainly unrelated to the procedure. No significant differences were recorded in the occurrence of any stroke in the long term. The presence of preoperative AF significantly affected long-term survival after CAS as well as being classified as American Society of Anesthesiologists class 3 at evaluation of the preoperative anesthesiology risk. The presence of preoperative AF also significantly affected long-term risk of stroke after both CAS and CEA.

Epub ahead of print. PMID: 32804291.   This is the abstract: Congenital bicuspid aortic valve (BAV) consists of two fused cusps and represents a major risk factor for calcific valvular stenosis. Herein, a fully coupled fluid-structure interaction (FSI) BAV model was developed from patient-specific magnetic resonance imaging (MRI) and compared against in vivo 4-dimensional flow MRI (4D Flow). FSI simulation compared well with 4D Flow, confirming direction and magnitude of the flow jet impinging onto the aortic wall as well as location and extension of secondary flows and vortices developing at systole: the systolic flow jet originating from an elliptical 1.6 cm2 orifice reached a peak velocity of 252.2 cm/s, 0.6% lower than 4D Flow, progressively impinging on the ascending aorta convexity. The FSI model predicted a peak flow rate of 22.4 L/min, 6.7% higher than 4D Flow, and provided BAV leaflets mechanical and flow-induced shear stresses, not directly attainable from MRI. At systole, the ventricular side of the non-fused leaflet revealed the highest wall shear stress (WSS) average magnitude, up to 14.6 Pa along the free margin, with WSS progressively decreasing towards the belly. During diastole, the aortic side of the fused leaflet exhibited the highest diastolic maximum principal stress, up to 322 kPa within the attachment region. Systematic comparison with ground-truth non-invasive MRI can improve the computational model ability to reproduce native BAV hemodynamics and biomechanical response more realistically, and shed light on their role in BAV patients' risk for developing complications; this approach may further contribute to the validation of advanced FSI simulations designed to assess BAV biomechanics.
