Salt substitute recommendations for heart failure patients may influence guideline-directed medical therapies titration. ESC Heart Fail 2024. [PMID: 38783593 DOI: 10.1002/ehf2.14706] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/16/2023] [Revised: 12/28/2023] [Accepted: 01/18/2024] [Indexed: 05/25/2024] Open
Abstract
AIMS Reducing sodium intake is necessary for patients with chronic heart failure (CHF). Salt substitutes (saltSubs) have become increasingly popular as recommendations by healthcare professionals (HCPs) as well as options for patients and their caregivers. However, their consumption is generally potassium based and remains poorly evaluated in CHF management. Their impact on guideline-directed medical therapies (GDMTs) also remains unknown. The primary objective of this study was to provide a description and estimate of HCP recommendations and reported use of saltSubs in France. Secondary objectives were to identify if there was an association between these recommendations by HCPs and the use of GDMTs. METHODS AND RESULTS A nationwide, questionnaire-based, cross-sectional, epidemiological study was conducted from September 2020 to July 2021. Data collection included baseline characteristics, the use and recommendations of saltSubs, and the use of GDMTs, which included (i) angiotensin-converting enzyme inhibitors (ACEis) and angiotensin receptor blockers (ARBs) or angiotensin receptor-neprilysin inhibitors (ARNis), (ii) mineralocorticoid receptor antagonists (MRAs), and/or (iii) beta-blockers (BBs). In total, 13% of HCPs advised saltSubs and 17% of patients and 22% of caregivers reported their consumption. CHF patients advised to take saltSubs did not differ in terms of left ventricular ejection fraction (EF) <40%, ischaemic origin, and New York Heart Association III-IV class, but were more recently hospitalized for acute HF (P = 0.004). HCPs who recommended saltSubs to patients were more likely to advise an anti-diabetic diet (P < 0.001), cholesterol-lowering diet (P < 0.001), and exercise (P = 0.018). In the overall population, ACEi/ARB/ARNi use was less frequent in case of saltSub recommendations (74% vs. 82%, P = 0.012). The concomitant prescription of none, one, two, or three GDMTs was less favourable in case of saltSub recommendations (P = 0.046). There was no significant difference for the presence of MRA (56% vs. 58%) and/or BB (78% vs. 82%). The under-prescription of ACEi/ARB/ARNi was found when patients had EF < 40% (P = 0.029) and/or EF ≥ 40% (P = 0.043). In the subgroup with left ventricular EF ≥ 40%, we found a higher thiazide use (P = 0.014) and a less frequent use of low EF GDMTs (P = 0.044) in case of being recommended saltSubs. CONCLUSIONS Beyond the well-established risk for hyperkalaemia, our preliminary results suggest a potentially negative impact of saltSubs on GDMT use, especially for ACEis/ARBs/ARNis in CHF management. saltSub recommendations and their availability from open sale outlets should be considered to avoid possible misuse or deference from GDMTs in the future. Informed advice to consumers should also be considered from HCPs or pharmacists.

Assessment of the Objective Effect of Virtual Reality for Preoperative Anxiety in Interventional Cardiology. Am J Cardiol 2023; 205:207-213. [PMID: 37611412 DOI: 10.1016/j.amjcard.2023.07.130] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Revised: 07/19/2023] [Accepted: 07/26/2023] [Indexed: 08/25/2023]
Abstract
The management of anxiety because of upcoming invasive coronary angiography (ICA) remains suboptimal. Previously published studies investigating the potential of virtual reality (VR) for the reduction of anxiety in ICA procedures used a subjective evaluation method. The purpose of this study was to determine whether the use of a VR program before ICA objectively decreases anxiety as assessed by the SD of normal to normal (SDNN). Lower SDNN is associated with worse anxiety. A total of 156 patients referred for ICA after a positive noninvasive test for coronary disease were included in the present randomized study. The interventional group benefited from the use of a VR mask in the transfer room before ICA, whereas the control group underwent the procedure as usual. In both groups, SDNN was measured before ICA. No statistical difference in SDNN was observed between the VR and control groups (45.5 ± 17.8 vs 50.6 ± 19.5, p = 0.12). The preoperative use of a VR mask for anxiolytic purposes in the setting of ICA did not result in a decrease in anxiety.

Abstract
Human nocardiosis usually involves the respiratory tract or the skin but may disseminate to virtually any organ, it occurs in immunocompromised hosts as well as individuals with no apparent predisposition. Involvement of the pericardium is uncommon, having been reported infrequently in the past, but mandates a special management. This report describes the first case in Europe of a patient with chronic constrictive pericarditis from nocardia brasiliens, successfully treated with pericardiectomy and appropriate antibiotic therapy.

Effect of adaptive servo-ventilation for central sleep apnoea in systolic heart failure on muscle sympathetic nerve activity: a SERVE-HF randomised ancillary study. Eur Respir J 2023; 61:13993003.00384-2022. [PMID: 36229051 PMCID: PMC9909211 DOI: 10.1183/13993003.00384-2022] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2022] [Accepted: 09/18/2022] [Indexed: 11/05/2022]
Abstract
BACKGROUND Adaptive servo-ventilation (ASV) effectively suppresses central sleep apnoea (CSA) but has been associated with increased all-cause and cardiovascular mortality in chronic heart failure patients with reduced ventricular ejection fraction (HFrEF). All-cause and, especially, cardiovascular mortality in chronic heart failure is highly correlated with sympathetic tone. This analysis of SERVE-HF data investigated the effect of ASV on sympathetic tone in patients with HFrEF and CSA. METHODS HFrEF patients in the SERVE-HF trial (left ventricular ejection fraction (LVEF) ≤45%, apnoea-hypopnoea index (AHI) ≥15 events·h-1 with predominant CSA) were randomly assigned to receive guideline-based heart failure treatment alone (controls) or plus ASV. For this analysis, the primary outcome was change in muscle sympathetic nerve activity (MSNA) at 3-month follow-up. The effects of baseline MSNA and change in MSNA over time on mortality in the main study were also assessed. RESULTS 40 patients with HFrEF were included in this analysis (age 71.3±11.7 years, LVEF 34.2±7.7%, 57.5% in New York Heart Association (NYHA) Functional Class II, 42.5% in NYHA Functional Class III, AHI 35.2±11 events·h-1). Sympathetic tone evolution during follow-up did not differ between groups (controls: 47.6±8.3 bursts·min-1 at baseline to 44.6±11.2 bursts·min-1; ASV group: 43.0±9.0 bursts·min-1 at baseline to 42.74±9.45 bursts·min-1). The reduction in sympathetic tone was associated with significantly increased cardiovascular mortality in the ASV group, whereas in the control group reduced sympathetic tone appeared to be protective. CONCLUSIONS Suppression of CSA with ASV did not seem to have a significant effect on chronic heart failure-related sympathetic activation. Simultaneous suppression of CSA and reduction in MSNA was associated with increased cardiovascular mortality.

Sequencing and titrating approach of therapy in heart failure with reduced ejection fraction following the 2021 European Society of Cardiology guidelines: an international cardiology survey. Eur J Heart Fail 2023; 25:213-222. [PMID: 36404398 DOI: 10.1002/ejhf.2743] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2022] [Revised: 09/26/2022] [Accepted: 11/16/2022] [Indexed: 11/22/2022] Open
Abstract
AIMS In symptomatic patients with heart failure and reduced ejection fraction (HFrEF), recent international guidelines recommend initiating four major therapeutic classes rather than sequential initiation. It remains unclear how this change in guidelines is perceived by practicing cardiologists versus heart failure (HF) specialists. METHODS AND RESULTS An independent academic web-based survey was designed by a group of HF specialists and posted by email and through various social networks to a broad community of cardiologists worldwide 1 year after the publication of the latest European HF guidelines. Overall, 615 cardiologists (38 [32-47] years old, 63% male) completed the survey, of which 58% were working in a university hospital and 26% were HF specialists. The threshold to define HFrEF was ≤40% for 61% of the physicians. Preferred drug prescription for the sequential approach was angiotensin-converting enzyme inhibitors or angiotensin receptor-neprilysin inhibitors first (74%), beta-blockers second (55%), mineralocorticoid receptor antagonists third (52%), and sodium-glucose cotransporter 2 inhibitors (53%) fourth. Eighty-four percent of participants felt that starting all four classes was feasible within the initial hospitalization, and 58% felt that titration is less important than introducing a new class. Age, status in training, and specialization in HF field were the principal characteristics that significantly impacted the answers. CONCLUSION In a broad international cardiology community, the 'historical approach' to HFrEF therapies remains the preferred sequencing approach. However, accelerated introduction and uptitration are also major treatment goals. Strategy trials in treatment guidance are needed to further change practices.

Feasibility and accuracy of linking a heart failure registry to the national claims database using indirect identifiers. Arch Cardiovasc Dis 2023; 116:18-24. [PMID: 36549971 DOI: 10.1016/j.acvd.2022.11.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2022] [Revised: 11/02/2022] [Accepted: 11/03/2022] [Indexed: 12/13/2022]
Abstract
BACKGROUND Heart failure (HF) registries include rich data on patient inclusion characteristics, but follow-up information is often incomplete. Medicoadministrative databases may provide less clinical information than registries, e.g. on left ventricular ejection fraction (LVEF), but long-term data are exhaustive and reliable. The combination of the two types of database is therefore appealing, but the feasibility and accuracy of such linking are largely unexplored. AIMS To assess the feasibility and accuracy of linking an HF registry (FRESH; FREnch Survey on Heart Failure) with the French National Healthcare System database (SNDS). METHODS A probabilistic algorithm was developed to link and match patient data included in the FRESH HF registry with anonymized records from the SNDS, which include: hospitalizations and diagnostic codes; all care-related reimbursements by national health system; and deaths. Consistency was assessed between deaths recorded in the registry and in the SNDS. A comparison between the two databases was carried out on several identifiable clinical characteristics (history of HF hospitalization, diabetes, atrial fibrillation, chronic bronchopneumopathy, severe renal failure and stroke) and on events during 1-year follow-up after inclusion. RESULTS Of 2719 patients included in the FRESH registry (1049 during decompensation; 1670 during outpatient follow-up), 1885 could be matched with a high accuracy of 94.3% for deaths. Mortality curves were superimposable, including curves according to type of HF and LVEF. The rates of missing data in the FRESH registry were 2.3-8.4% for clinical characteristics and 17.5% for hospitalizations during follow-up. The discrepancy rate for clinical characteristics was 3-13%. Hospitalization rates were significantly higher in the SNDS than in the registry cohort. CONCLUSIONS The anonymous matching of an HF research cohort with a national health database is feasible, with a significant proportion of patients being accurately matched, and facilitates combination of clinical data and a reduced rate of losses to follow-up.

Abstract
ObjectiveTo determine whether changes in pulmonary vascular resistance (PVR) and changes in pulmonary artery compliance (PCa) are associated with changes in exercise capacity assessed either by changes in peak oxygen consumption (V̇O2) or by changes in 6-min walk distance (6MWD) in patients with chronic thromboembolic pulmonary hypertension (CTEPH) undergoing balloon pulmonary angioplasty (BPA).MethodsInvasive haemodynamic parameters, peak V̇O2and 6MWD were measured within 24 h, before and after BPA (interval, 3.1±2.4 months) in 34 CTEPH patients without significant cardiac and/or pulmonary comorbidities, of which 24 received at least one pulmonary hypertension-specific treatment. PCa was calculated according to the pulse pressure method: PCa=([SV/PP]/1.76+0.1), where SV is the stroke volume and PP is the pulse pressure. The resistance-compliance (RC)-time of the pulmonary circulation was calculated as the PVR and PCa product.ResultsAfter BPA, PVR decreased (562±234versus290±106 dyn.s.cm−5;p<0.001), PCa increased (0.90±0.36versus1.63±0.65 mL.mmHg−1; p<0.001) but RC-time did not change (0.325±0.069versus0.321±0.083 s; p=0.75). There were improvements in peak V̇O2(1.11±0.35versus1.30±0.33 L.min-1; p <0.001) and in 6MWD (393±119versus432±100 m; p <0.001). After adjustment for age, height, weight and gender, changes in exercise capacity, assessed either by peak V̇O2and 6MWD, were significantly associated with changes in PVR, but not with changes in PCa.ConclusionsContrary to what has been reported in CTEPH patients undergoing pulmonary endarterectomy, in CTEPH patients undergoing BPA, changes in exercise capacity was not associated with changes in pulmonary artery compliance.

Abstract
AIMS The objective of this study was to determine the accuracy of right ventricular function (RVF) assessed by Cadmium Zinc Telluride ECG-gated SPECT equilibrium radionuclide angiocardiography (CZT-ERNA). METHODS AND RESULTS Twenty-one consecutive patients with cardiomyopathy (aged 54 ± 19 years; 62% male) were included. RV ejection fraction (EF) and volumes were analyzed by CZT-ERNA and compared with values obtained by cardiac magnetic resonance imaging (CMR). Mean values were not different between CZT-ERNA and MRI for RVEF (48.1 ± 10.4% vs 50.8 ± 10.0%; P = .23). Significant correlations (P < .0001) were observed between CZT-ERNA and MRI for RVEF, RV end-diastolic volume, and end-systolic volume (r = 0.81, r = 0.93, and r = 0.96, respectively). Bland-Altman analysis showed a mean difference (bias) between CZT-ERNA and MRI for RVEF of -2.69% (95% CI - 5.35 to - 0.42) with good agreement between the 2 techniques (limits of agreement, -14.3 to 8.99). Intraobserver and interobserver reproducibility of RVF measured by CZT-ERNA was high. CONCLUSION CZT-ERNA provides accurate, reproducible assessment of RVF and appears as a good alternative to cardiac magnetic resonance for the evaluation of the magnitude of RVF in patients with cardiomyopathy.

Abstract
Excessive ventilation (V̇E) during exercise, ascribed to heightened neural ventilatory drive and/or to increased "wasted" ventilation, is a feature of chronic thromboembolic pulmonary hypertension (CTEPH). In selected CTEPH patients, balloon pulmonary angioplasty (BPA) allows near-normalization of resting haemodynamic parameters but does not allow excess exercise hyperventilation to normalize. Neural ventilatory drive can be estimated by studying how arterial PCO2 (PaCO2), end-tidal PCO2 (PETCO2), V̇E and CO2 output (V̇CO2) change across the exercise-to-recovery transition during a cardiopulmonary exercise test. Increased "wasted" ventilation can be quantified by the physiological dead space fraction of tidal volume (VD/VT) calculated with the Enghoff simplification of the Bohr equation. These measurements were made before and after BPA in 22 CTEPH patients without significant cardiac and/or pulmonary comorbidities. Our observations suggest that before BPA, excessive hyperventilation was secondary to both heightened neural ventilatory drive and increased "wasted" ventilation; after BPA, measurements made across the exercise-to-recovery transition suggest that heightened neural ventilatory drive was no longer present.

Abstract
AIMS Hospitalization for acute heart failure (HF) is followed by a vulnerable time with increased risk of readmission or death, thus requiring particular attention after discharge. In this study, we examined the impact of intensive, early follow-up among patients at high readmission risk at discharge after treatment for acute HF. METHODS AND RESULTS Hospitalized acute HF patients were included with at least one of the following: previous acute HF < 6 months, systolic blood pressure ≤ 110 mmHg, creatininaemia ≥ 180 µmol/L, or B-type natriuretic peptide ≥ 350 pg/mL or N-terminal pro B-type natriuretic peptide ≥ 2200 pg/mL. Patients were randomized to either optimized care and education with serial consultations with HF specialist and dietician during the first 2-3 weeks, or to standard post-discharge care according to guidelines. The primary endpoint was all-cause death or first unplanned hospitalization during 6-month follow-up. Among 482 randomized patients (median age 77 and median left ventricular ejection fraction 35%), 224 were hospitalized or died. In the intensive group, loop diuretics (46%), beta-blockers (49%), angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (39%) and mineralocorticoid receptor antagonists (47%) were titrated. No difference was observed between groups for the primary endpoint (hazard ratio 0.97; 95% confidence interval 0.74-1.26), nor for mortality at 6 or 12 months or unplanned HF rehospitalization. Additionally, no difference between groups according to age, previous HF and left ventricular ejection fraction was found. CONCLUSIONS In high-risk HF, intensive follow-up early post-discharge did not improve outcomes. This vulnerable post-discharge time requires further studies to clarify useful transitional care services.

Abstract
Bronchopulmonary infections are a major trigger of cardiac decompensation and are frequently associated with hospitalizations in patients with heart failure (HF). Adverse cardiac effects associated with respiratory infections, more specifically Streptococcus pneumoniae and influenza infections, are the consequence of inflammatory processes and thrombotic events. For both influenza and pneumococcal vaccinations, large multicenter randomized clinical trials are needed to evaluate their efficacy in preventing cardiovascular events, especially in HF patients. No study to date has evaluated the protective effect of the COVID-19 vaccine in patients with HF. Different guidelines recommend annual influenza vaccination for patients with established cardiovascular disease and also recommend pneumococcal vaccination in patients with HF. The Heart Failure group of the French Society of Cardiology recently strongly recommended vaccination against COVID-19 in HF patients. Nevertheless, the implementation of vaccination recommendations against respiratory infections in HF patients remains suboptimal. This suggests that a national health policy is needed to improve vaccination coverage, involving not only the general practitioner, but also other health providers, such as cardiologists, nurses, and pharmacists. This review first summarizes the pathophysiology of the interrelationships between inflammation, infection, and HF. Then, we describe the current clinical knowledge concerning the protective effect of vaccines against respiratory diseases (influenza, pneumococcal infection, and COVID-19) in patients with HF and finally we propose how vaccination coverage could be improved in these patients.

Exercise hyperventilation and pulmonary gas exchange in chronic thromboembolic pulmonary hypertension: Effects of balloon pulmonary angioplasty. J Heart Lung Transplant 2021; 41:70-79. [PMID: 34742646 DOI: 10.1016/j.healun.2021.09.009] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2021] [Revised: 08/25/2021] [Accepted: 09/14/2021] [Indexed: 12/31/2022] Open
Abstract
BACKGROUND Excessive ventilation (V̇E) and abnormal gas exchange during exercise are features of chronic thromboembolic pulmonary hypertension (CTEPH). In selected CTEPH patients, balloon pulmonary angioplasty (BPA) improves symptoms and exercise capacity. How BPA affects exercise hyperventilation and gas exchange is poorly understood. METHODS In this longitudinal observational study, symptom-limited cardiopulmonary exercise tests and carbon monoxide lung diffusion (DLCO) were performed before and after BPA (interval, mean (SD): 3.1 (2.4) months) in 36 CTEPH patients without significant cardiac and/or pulmonary comorbidities. RESULTS Peak work rate improved by 20% after BPA whilst V̇E at peak did not change despite improved ventilatory efficiency (lower V̇E with respect to CO2 output [V̇CO2]). At the highest identical work rate pre- and post-BPA (75 (30) watts), V̇E and alveolar-arterial oxygen gradient (P(Ai-a)O2) decreased by 17% and 19% after BPA, respectively. The physiological dead space fraction of tidal volume (VD/VT), calculated from measurements of arterial and mixed expired CO2, decreased by 20%. In the meantime, DLCO did not change. The best correlates of P(Ai-a)O2 measured at peak exercise were physiological VD/VT before BPA and DLCO after BPA. CONCLUSIONS Ventilatory efficiency, physiological VD/VT, and pulmonary gas exchange improved after BPA. The fact that DLCO did not change suggests that the pulmonary capillary blood volume and probably the true alveolar dead space were unaffected by BPA. The correlation between DLCO measured before BPA and P(Ai-a)O2 measured after BPA suggests that DLCO may provide an easily accessible marker to predict the response to BPA in terms of pulmonary gas exchange.

MATERIAL AND METHODS A retrospective observational study including patients hospitalized for AHF RESULTS: 793 patients were included, 59.0% were men, 45.6% identified heart failure (HF) as the main cause of hospitalization; 36.0% were unaware of their HF. Mean age was 72.9 ± 14.5 years. The symptoms occurring the most before hospitalization were dyspnea (64.7%) and lower limb edema (27.7%). Prior to hospitalization, 47% had already experienced symptoms for 15 days; 32% of them for 2 months. Referral to hospital was made by the emergency medical assistance service (SAMU, 41.6%), a general practitioner (GP, 22.3%), a cardiologist (19.5%), or the patient (16.6%). The modality of referral depended more on symptom acuteness than on type of symptoms. A sudden onset of AHF symptoms led to making an emergency call or to spontaneously attending an emergency room (ER), whereas cardiologists were consulted when symptoms had already been present for over 15 days. Cardiologists referred more patients to cardiology departments and fewer patients to the ER than general practitioners or the SAMU. CONCLUSION This study described the French healthcare system pathways before, during and after hospitalization AHF. AHF clinic network should be developed to provide adequate care for all HF patients and create awareness regarding AHF symptoms.

Multimodal Imaging to Understand Left Ventricular Systolic Dysfunction in a Patient With Sepsis-Related Myocardial Calcification. JACC Case Rep 2021; 3:966-970. [PMID: 34317667 PMCID: PMC8311337 DOI: 10.1016/j.jaccas.2021.04.037] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2021] [Revised: 04/26/2021] [Accepted: 04/29/2021] [Indexed: 11/20/2022]
Abstract
A 52-year-old man with acute peritonitis developed severely decreased left ventricular (LV) ejection fraction. Multimodal imaging allowed the diagnosis of sepsis-related myocardial calcification. Moreover, 2-dimensional speckle tracking echocardiography allowed a better understanding of LV dysfunction and confirmed the hypothesis that regional LV dysfunction is in accordance with the localization of calcifications.

Prognosis of Coronary Atherosclerotic Burden in Non-Ischemic Dilated Cardiomyopathies. J Clin Med 2021; 10:jcm10102183. [PMID: 34070034 PMCID: PMC8158137 DOI: 10.3390/jcm10102183] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2021] [Revised: 05/12/2021] [Accepted: 05/14/2021] [Indexed: 01/07/2023] Open
Abstract
Background: Atherosclerosis is associated with a worse prognosis in many diseases such as ischemic cardiomyopathy, but its impact in non-ischemic dilated cardiomyopathy (dCMP) is lesser known. Our aim was to study the prognostic impact of coronary atherosclerotic burden (CAB) in patients with dCMP. Methods: Consecutive patients with dCMP and left ventricular (LV) dysfunction diagnosed by concomitant analysis of invasive coronary angiography (ICA) and CMR imaging were identified from registry-database. CAB was measured by Gensini score. The primary composite endpoint was the occurrence of major adverse cardiovascular events (MACE) defined as cardiovascular (CV) mortality, non-fatal MI and unplanned myocardial revascularization. The results of 139 patients constituting the prospective study population (mean age 59.4 ± 14.7 years old, 74% male), average LV ejection fraction was 31.1 ± 11.02%, median Gensini score was 0 (0–3), and mid-wall late gadolinium enhancement (LGE) was the most frequent LGE pattern (42%). Over a median follow-up of 2.8 years, 9% of patients presented MACE. Patients with MACE had significantly higher CAB compared to those who were free of events (0 (0–3) vs. 3.75 (2–15), p < 0.0001). CAB remained the significant predictor of MACE on multivariate logistic analysis (OR: 1.12, CI: 1.01–1.23, p = 0.02). Conclusion: High CAB may be a new prognostic factor in dCMP patients.

Abstract
AIMS The aim was to assess the effect of a telemonitoring programme vs. standard care (SC) in preventing all-cause deaths or unplanned hospitalisations in heart failure (HF) at 18 months. METHODS AND RESULTS OSICAT was a randomised, multicentre, open-label French study in 937 patients hospitalised for acute HF ≤12 months before inclusion. Patients were randomised to telemonitoring (daily body weight measurement, daily recording of HF symptoms, and personalised education) (n = 482) or to SC (n = 455). Mean ± standard deviation number of events for the primary outcome was 1.30 ± 1.85 for telemonitoring and 1.46 ± 1.98 for SC [rate ratio 0.97, 95% confidence interval (CI) 0.77-1.23; P = 0.80]. In New York Heart Association (NYHA) class III or IV HF, median time to all-cause death or first unplanned hospitalisation was 82 days in the telemonitoring group and 67 days in the SC group (P = 0.03). After adjustment for known predictive factors, telemonitoring was associated with a 21% relative risk reduction in first unplanned hospitalisation for HF [hazard ratio (HR) 0.79, 95% CI 0.62-0.99; P = 0.044); the relative risk reduction was 29% in patients with NYHA class III or IV HF (HR 0.71, 95% CI 0.53-0.95; P = 0.02), 38% in socially isolated patients (HR 0.62, 95% CI 0.39-0.98; P = 0.043), and 37% in patients who were ≥70% adherent to body weight measurement (HR 0.63, 95% CI 0.45-0.88; P = 0.006). CONCLUSION Telemonitoring did not result in a significantly lower rate of all-cause deaths or unplanned hospitalisations in HF patients. The pre-specified subgroup results suggest the telemonitoring approach improves clinical outcomes in selected populations but need further confirmation.

Abstract
Abstract
Background
Cardiac resynchronization (CRT) as well as implantable cardiac defibrillator (ICD) in primary prevention should be considered in patients with heart failure and reduced ejection fraction (HFrEF) only when pharmacological treatment has been optimized.
Purpose
we sought to analyze pharmacological treatments according to the presence or not of CRT-P, CRT-D or ICD in real life HFrEF patients by using a multicenter survey.
Methods
the survey (NCT01956539) was carried out between 2015 and 2018 in 32 hospitals and included 2735 patients with HF who gave their consent during consultation or hospitalization. In this study, we analyzed only outpatients with chronic HFrEF treated for more than 6 months.
Results
among 1061 patients studied, 138 had CRT-P or CRT-D and 215 had ICD for primary prevention. The main clinical characteristics were: age 65±13 years, ischemic heart disease in, NYHA classes 1, 2, 3 and 4 in 15%, 52%, 23% and 10% cases respectively, systolic blood pressure 115mmHg [IQR 104–129], heart rate 70bpm [IQR 60–80], eGFR 64ml/min/1.73m2 [IQR 46–83]and LVEF was 30% [IQR 24–34]. The table shows the rate of use of evidence-based drugs and the dose for ACEi/ARB and betablockers, according to the presence of ICD or CRT.
HFrEF CRT-P or D ICD (primary prevention) n=1061 n=138 n=215 Loop diuretics 78.2% 79.7% 74.9% ACEi or ARB 65.2% 75.4% 67.3% Sacubitril/valsartan 5.9% 8.5% 9.5% Betablockers 72.3% 83.9% 76.8% Mineralocorticoid antagonists 45.7% 63.6% 60.2% ACEi/ARB mean % maxi dose 77 81 83 Beta-blockers mean % maxi dose 74 63 79
Conclusion
these results suggest that pharmacological treatment remains poorly optimized in a number of patients with HFrEF who received ICD or CRT

Abstract
Abstract
Background
According to last ESC guidelines, the diagnosis of heart failure with midrange and preserved left ventricular ejection fraction (HFmrEF-HF and HFpEF) requires at least one of the following imaging criteria: LV hypertrophy with LVMI >115g/m2 in men and 95g/m2 in women, left atria dilation with LAVI >34ml/m2, TDI e' wave average <9cm/s and E/e' average ≥13.
Purpose
We analyzed the prevalence of these imaging criteria in real life patients who are labeled HFmrEF or HFpEF by using a multicenter survey on HF.
Methods
Our survey (NCT01956539) was carried out in 32 hospitals between 2015 and 2018 and included 2735 HF patients who gave their consent during consultation or hospitalization. The diagnosis of HF was left to the discretion of investigators. Besides clinical and biological data, echocardiographic data (<1 month before or <3 months after inclusion) was collected in an electronic database. No echographic variable except the LVEF was mandatory to be included.
Results
Among the 523 and 765 HF patients who were labeled respectively as HFmrEF-HF and HFpEF, the 4 echographic variables required for the diagnosis of HFmrEF or HFpEF were obtained in 512 patients. The median age was 74y [IQR 62–82], HF was de novo in 28%, AF in 34%, median NTproBNP was 1563 pg/mL [IQR 500–4372]. At least one of the 4 diagnostic criteria was present in all patients but 2, and patients had 2, 3 or 4 criteria in 43%, 37% and 1% of cases. The table shows only little differences between HFmrEF and HFpEF or de novo HF regarding the rate of each diagnostic criteria. There was no difference regarding the date of inclusion, i.e. before or after the last ESC guidelines.
Table 1 All HF patients De novo HF HFpEF HFmrEF mrEF or pEF (n=143) (n=293) (n=219) LVMI >115g/m2 (men) or 95g/m2 (women) 69.6% 64.3% 68.6% 70.2% LAVI >34ml/m2 74.2% 73.3% 80.4% 68.9% e' average <9cm/s 64.1% 55.3% 55.9% 76.1% E/e' average ≥13 35.4% 38.6% 37.3% 32.8%
Conclusion
The diagnosis of HFpEF or mrEF may be difficult and requires comprehensive echocardiography including all diagnostic variables because each single diagnostic criteria are present in only 33 to 80% cases.

Abstract
Pulmonary hypertension (PH) is a common and severe complication of heart failure (HF). Consequently, HF is the leading cause of PH. For many years, specialists have attempted to better understand the pathophysiology of PH in HF, to define its prevalence and its impact on prognosis in order to improve the therapeutic management of these patients. Nowadays, despite the recent guidelines published on the subject, several points remain unclear or debated, and until now, no study has demonstrated the efficacy of any treatment. The aim of this review is to report the evolution of the concepts on post‐capillary PH (diagnosis, prevalence, prognosis, and therapeutics). The main issues are raised, focusing especially on the link between structural alterations and haemodynamic abnormalities, to discuss the possible reasons for treatment failures and future potential targets.

Abstract
When an electric current is passed through a rare-gas alkali plasma the electron temperature rises above the gas temperature. This effect was investigated in a streaming argon-potassium plasma at atmospheric pressure and a gas temperature of 2000 °K. The applicability of the line reversal method to the measurement of the electron temperature has been investigated. General conditions under which the electron temperature equals the line reversal temperature have been derived. In the case studied, the plasma had to be optically thick for the resonance radiation used. The electron temperature was measured with this method as a function of the current density. The results were compared with the values calculated from the theory and with the values calculated from the also measured conductivities. For electron temperatures above 2400 °K all three give the same results.

Abstract
PURPOSE The transconjunctival sutureless vitrectomy (TSV 25) is a new technique showing substantial progress. METHODS A prospective study of 66 eyes of 66 patients who underwent surgical procedures using the transconjunctival standard vitrectomy system (TSV 25), between June 2004 and June 2005. The results were compared with the results in an equivalent population (66 patients) that underwent vitrectomy with a standard 20-gauge system. RESULTS The most important differences between groups were 1) shorter surgical time in the 25-gauge vitrectomy group than in the 20-gauge group, with a mean time of 28.15+/-5.50 min for group 1 and 44.15+/-5.64 min for group 2 (p<0.001) and 2) lower mean postoperative intraocular tension in the first group of patients: in this group, the intraocular tension before surgery was a mean of 16.27+/-1.76 mmHg, decreasing to 12.17+/-1.36 mmHg, with a posterior increase to normal values of 15.06+/-1.66 mmHg at 7 days after surgery and a mean of 16.10+/-1.51 mmHg at 15 days. This decrease was not observed in the group of patients who underwent 20-gauge vitrectomy surgery. The other postoperative complications were similar in both groups except for four cases of anterior proliferation and two cases of fibrinous uveitis in group 2. CONCLUSION The transconjunctival sutureless system (TSV 25) decreases surgical time and postoperative inflammation, with optimal postoperative patient comfort, but currently the accurate selection of patients remains important.

Abstract
INTRODUCTION In diabetic patients, we often need to perform cataract and pars plana vitrectomy. Two different techniques are currently valid: 1) phacoemulsification and pars plana vitrectomy and 2)pars plana lensectomy and posterior vitrectomy. METHODS Retrospective study of two different groups of type 2 diabetic patients: those receiving 1) phacoemulsification and pars plana vitrectomy or 2) pars plana lensectomy and posterior vitrectomy. RESULTS On statistical analysis there were no differences in complications between the two groups. The effect on visual acuity was similar in both groups. DISCUSSION The association of cataract surgery and posterior vitrectomy is a valid technique for treating diabetic retinopathy complications. In the present study, the complications of the two techniques were similar, the most important concerning only anterior chamber opening in the first group. CONCLUSION The two techniques of cataract extraction and pars plana vitrectomy at the same time have no differences in their results and are valid for treatment of diabetic patients.

Abstract
OBJECTIVE To evaluate the economic effect in terms of health costs of alcohol abuse in Spain. DESIGN The most up-to-date available, secondary sources of information were used. The period for the costs calculation was a natural year, with the prices adjusted to pesetas in 1996. The focus was based on the prevalence of cases per period. All the information referred to the whole of Spain. SETTING Health costs were broken down into out-patient attendance, hospital emergencies, admissions, treatment at special centres and other health expenditure. MEASUREMENTS AND MAIN RESULTS The total health cost attributable to alcoholism was 177,084 million pesetas, broken down as follows: a) cost of hospital admissions: 93,644 million pesetas (52.88%); b) cost of out-patient attendance: 34,600 million (19.53%); c) cost of treatment at special centres: 18,029 million (10.18%); d) cost of hospital emergencies: 10,481 million (5.91%); and e) other health expenditure: 20,330 million pesetas (11.48%). CONCLUSIONS The figures arrived at do not cover the total cost of alcohol abuse, since a conservative approach was adopted. They stand as a minimum of the expenditure in our country. Some are direct costs on health authorities, whereas others can be managed as a cost-opportunity problem.

Abstract
The Cerdanya valley in the eastern Pyrenees has a physical unity into which a political frontier has been imposed to divide it. The social and cultural repercussions of this Franco-Spanish border have created obstacles to marriage which are not due to topography. Choice of month of marriage is under cultural control and the study of seasonality in marriages recorded in the registers of all the Cerdan parishes on both sides of the border demonstrated differences over time and between French and Spanish sectors. It is suggested that these changes demonstrate the process of distancing of the two populations. Cluster and correspondence analysis showed progressive differentiation of the seasonality patterns of the French and Spanish Cerdans despite the geographic unity of the valley. Sociocultural factors are presumed responsible.

Abstract
A retrospective study was made of 26 patients with AIDS who initially presented with retinitis as the only clinical manifestation of cytomegalovirus infection (39 eyes). Sixty-five induction or re-induction therapeutic courses were administered with intravitreal ganciclovir. The efficiency rate of therapy was 93.8%. Thirty-eight maintenance therapeutic courses (200 micrograms/week) were evaluated. The non-compliance rate was 23%. Bilateral retinitis occurred in 44.4% of cases. The systemic administration of therapy had to be substituted for the intravitreal administration in 32% of patients during the clinical course of their conditions. The mean survival rate was 9.5 months. Both retinal detachment and vitreal hemorrhage occurred in 5% of patients. When retinitis is the first clinical manifestation of cytomegalovirus infection, therapy with intravitreal ganciclovir is efficacious to inactivate lesions. Although bilateral retinitis and extraocular dissemination are common, the mean survival rate is high.

Abstract
In this paper the records of 7844 marriages in the parishes of French and Spanish sectors of the Cerdanya Valley have been analysed. The Cerdanya is an eastern Pyrenean valley, today divided by the Franco-Spanish border, but once united within Catalonia. The results have been reported on the one hand on a small scale using local place names, and on the other hand on a wider scale across France and Spain, because interest lies both in the geographic range from which some marital partners have come and in the relative proportions of brides and grooms from the French and Spanish parts of Cerdanya and from adjacent districts. Both mountains and the Franco-Spanish border are shown to have reduced the likelihood of marriage. Inaccessible mountain barriers appear to have been a greater obstacle to marital movement than the border. Adjacent districts and local provinces have provided a greater proportion of brides and grooms than more distant ones, but thereafter frequencies from the further regions do not decrease with greater distance. More marital partners have moved from Spain to France than vice-versa, and mobility of grooms exceeded mobility of brides. Results are relevant to genetics and the current European interest in nationality and ethnicity.
