Prognostic influence of acute decompensated heart failure in patients planned for transcatheter aortic valve implantation.

OBJECTIVE: The aim of our study was to evaluate the outcome of patients with severe aortic stenosis presenting with acute decompensated heart failure (ADHF) and planned for transcatheter aortic valve implantation (TAVI) and to study the variables influencing their prognosis. METHODS: Our retrospective study included 801 patients planned for TAVI in our center. Seven hundred and fifty-six underwent TAVI and were categorized according to ADHF as the initial clinical presentation into two groups: ADHF group (n = 261) and no-ADHF group (n = 495). Pre as well as periprocedural outcomes and 1 year mortality were analyzed. RESULTS: Among the patients planned for the TAVI procedure, 45 patients remained untreated: 35 patients died while waiting to undergo TAVI which represented 20% of all deaths in our study, ADHF was observed in 23 of 45 (51%) these untreated patients. The 1-year all-cause mortality rate was significantly higher in the ADHF group versus the no-ADHF group (27% vs. 15%, p < .0001). In multivariate analysis, male gender (odds ratio [OR] =2.5, 95% confidence interval [CI]: 1.37-4.57, p = .03), body mass index <25 kg/m2 (OR = 2.76, 95% CI: 1.51-5.04, p = .0009), and logistic EuroSCORE II ≥20% (OR = 3.04, 95% CI: 1.56-5.94, p = .001) were associated with a higher 1-year mortality in the ADHF group. CONCLUSION: The patients eligible for TAVI presenting with ADHF were associated with a higher mortality for both: while on the waiting list for TAVI as well as at 1-year follow-up and thus asking for clearer criteria to prioritize action in this high-risk TAVI patients.

Impact of video on the understanding and satisfaction of patients receiving informed consent before elective inpatient coronary angiography: A randomized trial.

BACKGROUND: Appropriate information about the benefits and risks of invasive procedures is crucial, but limited data is available in this field. The aim of this study was to evaluate the incremental value of a short video about coronary angiography compared with standard information, in terms of patient understanding, satisfaction and anxiety. METHODS: This prospective multicenter study included patients admitted for scheduled coronary angiography, who were randomized to receive either standard information or video information by watching a three-dimensional educational video. After information was delivered, patients were asked to complete a dedicated 16-point information questionnaire, as well as satisfaction and anxiety scales. RESULTS: From 21 September to 4 October 2015, 821 consecutive patients were randomized to receive either standard information (n=415) or standard information with an added educational video (n=406). The information score was higher in the video information group than in the standard group (11.8±2.8 vs 9.5±3.1; P<.001). This result was consistent across age and education level subgroups. Self-reported satisfaction was also higher in the video information group (8.4±1.9 vs. 7.7±2.3; P<.001), while anxiety level did not differ between groups. The variables associated with a higher information score were the use of the educational video, younger age, higher level of education, previous follow-up by a cardiologist, prior information about coronary angiography and previous coronary angiography. CONCLUSIONS: In comparison with standard information, viewing a dedicated educational video improved patients' understanding and satisfaction before scheduled coronary angiography. These results are in favor of widespread use of this incremental information tool.

Acute coronary syndrome in women: rising hospitalizations in middle-aged French women, 2004-14.

Aims: We aimed to analyse trends in annual incidence of hospitalized acute coronary syndrome (ACS) in France from 2004 to 2014. Methods and results: Primary diagnosis of ACS and subtypes on admissions were selected in national and exhaustive French Hospitalization Database from 2004 to 2014. Age-standardized rates were computed using standardization on the census of the 2010 European population and mean annual percent changes were estimated by using Poisson regression model. In 2014, 113 407 patients, 36 480 women (32.2%) and 76 927 men (67.8%) were hospitalized for ACS. Among women, the proportion aged under 65 years was 25.2% (n = 9206) and there was 34.4% of STEMI, 18.2% of NSTEMI and 47.4% of UA. From 2004 to 2014, the rates of age-standardized admissions for ACS in women less than 65 years old increased by 6.3%.This rise in ACS was driven by significant increases in STEMI (+21.7%) and NSTEMI (+53.7%). The largest increase in STEMI mean annual percent change was observed among women aged 45-54 years old (+3.6%/per year). After 65 years of age, significant decreases in all ACS types were observed. Conclusion: This nationwide study showed substantial rising trends in STEMI annual incidence, especially among younger women. This increase could be attributed to increase in smoking and obesity. Efforts to strengthen primary prevention of CVD in younger women is needed as the main risk factors are modifiable, and as there is a growing evidence of higher short-term mortality of CHD in women.

Socioeconomic factors and mortality in diastolic heart failure.

BACKGROUND: Mortality in patients with heart failure with preserved ejection fraction (HFPEF) has remained stable over recent decades. Few studies have explored prognostic characteristics specifically in HFPEF, and none of them has assessed the potential impact of socioeconomic factors. We aimed to evaluate the impact of socioeconomic factors on all-cause and cardiovascular mortality in HFPEF patients. MATERIALS AND METHODS: We used data from the French ODIN cohort. All patients with heart failure and a left ventricular ejection fraction (LVEF) > 45%, included in ODIN between July 2007 and July 2010, were eligible here. Socioeconomic, demographic, clinical, biological and therapeutic data were collected at inclusion. The endpoints were all-cause and cardiovascular mortality between inclusion and 30 September 2011. The impact of patient socioeconomic characteristics on mortality was assessed using Cox regression models. RESULTS: Of 575 HFPEF patients considered, 58·6% were male; their mean age was 71·1 ± 13·5 years, and their mean LVEF was 58·1 ± 8·5%. After adjustment for confounders, living alone and limitations on activities of daily living were associated with all-cause mortality [HR = 1·77, 95%CI(1·11-2·81) and 2·61(1·35-5·03), respectively] and cardiovascular mortality [2·26 (1·24-4·10) and 3·16 (1·33-7·54), respectively]. Having a professional occupation was associated with a lower cardiovascular mortality only [0·37(0·15-0·94)]. CONCLUSIONS: Poor social conditions impair survival in patients with HFPEF. These findings may shed new light on how best to detect HFPEF patients with high health-care needs.

Ischemic stroke associated with left cardiac catheterization: the importance of modifiable and non-modifiable risk factors.

BACKGROUND: Stroke associated with left cardiac catheterization is a devastating complication, and its incidence has not changed over the decades. We investigated the incidence, in-hospital outcomes and the modifiable and non-modifiable risk factors for periprocedural ischemic stroke. METHODS: Our retrospective cohort study included all patients experiencing periprocedural ischemic stroke among the 24,500 patients who underwent left cardiac catheterization between January 2003 and October 2010. The case group was compared with a group of control patients randomly selected among those who underwent the procedure during this period. RESULTS: Ischemic cerebrovascular events attested by brain imaging occurred in 37 patients (0.15% of procedures), transient ischemic attack occurred in 9 cases, and persistent neurological deficit occurred in 28 cases. Patients who developed strokes were more likely to be older and were more often female with a greater prevalence of comorbidities. Emergency and longer procedures were more frequent in patients in the case group who had more coronary complications. A multivariate analysis identified diabetes mellitus (adjusted odds ratio (OR) 4.2; 95% CI 1.8-9.9; P < .001), chronic renal dysfunction (OR 2.4; 95% CI 1.1-5.4; P < .001), known cerebrovascular disease (OR 5.1; 95% CI 2.3-11.5; P < .001), emergency procedure (OR 3.1; 95% CI 1.4-9.2; P < .01) and recent congestive heart failure (OR 6.1; 95% CI 2.9-13; P < .001) as independent predictors for stroke. The independent modifiable predictive factors were represented by left ventricular angiography (OR 7.5; 95% CI 2.7-21; P < .001), and low operator volume (OR 3.1; 95% CI 1.3-7.4; P < .01). CONCLUSION: Limiting the performance of left cardiac catheterization to high volume operators and avoiding unnecessary left ventricular angiography may reduce periprocedural ischemic stroke.

Methyl donor deficiency induces cardiomyopathy through altered methylation/acetylation of PGC-1α by PRMT1 and SIRT1.

Cardiomyopathies occur by mechanisms that involve inherited and acquired metabolic disorders. Both folate and vitamin B12 deficiencies are associated with left ventricular dysfunction, but mechanisms that underlie these associations are not known. However, folate and vitamin B12 are methyl donors needed for the synthesis of S-adenosylmethionine, the substrate required for the activation by methylation of regulators of energy metabolism. We investigated the consequences of a diet lacking methyl donors in the myocardium of weaning rats from dams subjected to deficiency during gestation and lactation. Positron emission tomography (PET), microscope and metabolic examinations evidenced a myocardium hypertrophy, with cardiomyocyte enlargement, disturbed mitochondrial alignment, lipid droplets, decreased respiratory activity of complexes I and II and decreased S-adenosylmethionine:S-adenosylhomocysteine ratio. The increased concentrations of triglycerides and acylcarnitines were consistent with a deficit in fatty acid oxidation. These changes were explained by imbalanced acetylation/methylation of PGC-1α, through decreased expression of SIRT1 and PRMT1 and decreased S-adenosylmethionine:S-adenosylhomocysteine ratio, and by decreased expression of PPARα and ERRα. The main changes of the myocardium proteomic study were observed for proteins regulated by PGC-1α, PPARs and ERRα. These proteins, namely trifunctional enzyme subunit α-complex, short chain acylCoA dehydrogenase, acylCoA thioesterase 2, fatty acid binding protein-3, NADH dehydrogenase (ubiquinone) flavoprotein 2, NADH dehydrogenase (ubiquinone) 1α-subunit 10 and Hspd1 protein, are involved in fatty acid oxidation and mitochondrial respiration. In conclusion, the methyl donor deficiency produces detrimental effects on fatty acid oxidation and energy metabolism of myocardium through imbalanced methylation/acetylation of PGC-1α and decreased expression of PPARα and ERRα. These data are of pathogenetic relevance to perinatal cardiomyopathies.

Fourteen-Year Temporal Trends in Patients Hospitalized for Mitral Regurgitation: The Increasing Burden of Mitral Valve Prolapse in Men.

Mitral regurgitation (MR) is the second most common valvular heart disease in Europe. The aging of the population and the increase in post-infarction survival could increase the prevalence of MR. To estimate the burden of patients hospitalized for MR in France in 2019 and temporal trends by etiology and sex from 2006 to 2020, we selected all patients hospitalized for MR using the national hospital database. In 2019, 49.2% of such patients had mitral valve prolapse (MVP), 17.1% had ischemic MR, 9.9% had rheumatic MR and 4.4% had MR with cardiomyopathy. The mean age of MVP patients was 67.8 years, and 34% were women. Among 89% of MVP inpatients who had received mitral valve repair or replacement, 55% received surgical repair, 13% received percutaneous repair and 25% received replacement. The all-cause mortality of one year after a mitral procedure of MVP was 5.4%. Among ischemic MR inpatients, 29% have had a mitral valve replacement, 16% a surgical repair and 19% a percutaneous repair. Between 2006 and 2019, the age-standardized rates of patients hospitalized for MVP have increased by 60%, especially in men (+80%) with 5.3/100,000 Person-Years (PY). The age-standardized rates of patients hospitalized for ischemic MR have increased by 25% with 1.8/100,000 PY; that of rheumatic MR has decreased by 36%. The study found that the burden of MVP in hospitals has increased substantially, especially among men. These results emphasize the need to monitor these temporal trends and anticipate care needs in the coming years.

Association of IL1B polymorphism with left ventricular systolic dysfunction: a relation with the release of interleukin-1ß in stress condition.

OBJECTIVE: Proinflammatory cytokines play a major role in the pathomechanisms of heart failure. Besides this, the influence of mental stress on heart failure is poorly documented despite its effects on sympathetic stimulation of interleukin-1ß (IL-1ß) secretion. We examined whether the polymorphisms of proinflammatory cytokines are predictors of left ventricular systolic dysfunction (LVSD) and if so, whether such associations are related to the secretion of these cytokines, in 572 consecutive patients under mental stress produced by coronary angiography. METHODS: We examined IL-1RN (VNTR), IL1A-889 C>T, IL1B-511 C>T, IL6-174 G>C and TNFA-308 G>A, according to LVSD (left ventricular ejection fraction, <40%). Saliva IL-1ß, serum tumour necrosis factor-α and C-reactive protein were assayed in basal (T0 and T2, before and after coronary angiography) and stress (T1) conditions. MAIN RESULTS: The 42.1% of patients with LVSD had a 1.5-fold higher frequency of IL1B T allele (P<0.001). IL1B-511TT was associated with LVSD (P=0.008) and with a decrease in IL-1ß level in saliva at T1 (P=0.013). IL-1ß was the highest at T1 (P<0.001) and was associated with left ventricular ejection fraction (P=0.002). The IL1B TT genotype and the C-reactive protein were the two independent predictors of LVSD in multivariate analysis, with an odds ratio of 2.7 (95% confidence interval: 1.3-5.5; P=0.008) and 1.1 (95% confidence interval: 1.1-1.2; P<0.001), respectively. CONCLUSION: IL1B was a predictor of LVSD and of the decreased IL-1ß response to stress. This suggests that IL1B exerts an influence on LVSD through its effect on IL-1ß secretion.

French annual national observational study of 2015 outpatient and inpatient healthcare utilization by approximately half a million patients with previous heart failure diagnosis.

BACKGROUND: Heart failure management guidelines have been published, but the degree of adherence to these guidelines remains unknown. AIMS: To study in 2015 healthcare utilization and causes of death for people previously identified with heart failure. METHODS: The national health data system was used to identify adult general scheme (86% of the French population) hospitalized for heart failure between 2011 and 2014 or with only a long-term chronic disease allowance for heart failure. The frequency and median (interquartile range) of at least one healthcare use among those still alive in 2015 was calculated. RESULTS: A total of 499,296 adults (1.4% of the population) were included, and 429,853 were alive in 2015; median age 79 (68-86) years. At least one utilization was observed for a general practitioner in 95% of patients (median 8 [interquartile range 5-13] consultations), a cardiologist in 42% (2 [1-3]), a nurse in 78% (16 [4-100]), a loop diuretic in 64% (11 [8-12] dispensations), an aldosterone antagonist in 21% (8 [5-11]), a thiazide in 15% (7 [4-11]), a renin-angiotensin system inhibitor in 68% (11 [8-13]), a beta-blocker in 65% (11 [7-13]), a beta-blocker plus a renin-angiotensin system inhibitor in 57%, and a beta-blocker plus a renin-angiotensin system inhibitor plus an aldosterone antagonist in 37%. Hospitalization for heart failure was present for 8% (1 [1,2]). Higher levels of healthcare utilization were observed in the presence of hospitalization for heart failure before 2015. Among the 13.9% of people who died in 2015, heart failure accounted for 8% of causes, cardiovascular disease accounted for 39%. CONCLUSIONS: General practitioners and nurses are the main actors in the regular follow-up of patients with heart failure, whereas cardiologist consultations and dispensing of first-line treatments are insufficient with respect to guidelines.

Vericiguat for the treatment of heart failure: mechanism of action and pharmacological properties compared with other emerging therapeutic options.

INTRODUCTION: The significant morbidity and mortality in patients with heart failure (HF), notably in the most advanced forms of the disease, justify the need for novel therapeutic options. In the last year, the soluble guanylate cyclase (sGC) stimulator, vericiguat, has drawn the attention of the medical community following the report of reduced clinical outcomes in patients with worsening chronic HF (WCHF). AREAS COVERED: The authors review the available data on the mechanism of action of vericiguat (cyclic guanosine monophosphate (cGMP) pathway), its clinical development program, its role in HF management, and its future positioning in the therapeutic recommendations. EXPERT OPINION: cGMP deficiency has deleterious effects on the heart and contributes to the progression of HF. Different molecules, including nitric oxide (NO) donors, phosphodiesterase inhibitors, and natriuretic peptides analogues, target the NO-sCG-cGMP pathway but have yielded conflicting results in HF patients. Vericiguat acts as a sGC stimulator thus targeting the NO-sGC-cGMP pathway by a different mechanism that complements the current pharmacotherapy for HF. Vericiguat has shown an additional statistical add-on therapy efficacy by reducing morbi-mortality in patients with WCHF. A better evaluation of HF severity might be an important determinant to guide the use of vericiguat among the available therapies.

Safe Discharge Home With Telemedicine of Patients Requiring Nasal Oxygen Therapy After COVID-19.

Introduction: The COVID-19 pandemic created challenges to healthcare systems worldwide. To allow overwhelmed hospitals to focus on the most fragile and severely ill patients, new types of management had to be set up. During the pandemic, patients with COVID-19 from greater Paris area were monitored at home using a web-based remote system called COVIDOM™, using self-administered questionnaires, which triggered alerts to a regional control center. To ease hospital discharge and to prevent hospital from being overwhelmed, patients still requiring low-flow oxygen therapy discharged home were also included in this telemedicine solution. We aim to evaluate the safety of this original management. Methods: We conducted a retrospective multicenter cohort of patients discharged home from hospital after COVID-19 and still requiring nasal oxygen therapy, who were monitored by questionnaire and trained physicians using COVIDOM. During late follow-up, the status of the patients using a Euro-Qol (EQ-5D-5L) questionnaire, and the Medical Research Council (MRC) Dyspnea scale was collected. Results: From March 21st to June 21st 2020, 73 COVID-19 patients still receiving nasal oxygen at hospital discharge were included. Median [Inter-Quartile Range (IQR)] age was 62.0 [52.5-69.0] years, 64.4% were male. Altogether, risk factors were observed in 49/73 (67%) patients, mainly hypertension (35.6%), diabetes mellitus (15.1%) and active neoplasia (11.0%). Among the cohort, 26% of patients were previously managed in ICU. Oxygen therapy was required for a median [IQR] of 20 [16-31] days. No death or urgent unplanned hospitalization were observed during the COVIDOM telemonitoring. During the late follow-up evaluation (6 months after inclusion), the mean EQ-5D-5L questionnaire score was 7.0 ± 1.6, and the mean MRC dyspnea scale was 0.8 ± 1.0, indicating absence of dyspnea. Five patients have died from non-COVID causes. Conclusions: In this preliminary study, early discharge home of patients with severe COVID-19 disease who still required low-oxygen therapy seems to be safe.

Adherence to diagnostic and therapeutic practice guidelines for suspected cardiac implantable electronic device infections.

BACKGROUND: Despite guidelines describing the optimal diagnostic and therapeutic procedures for patients with suspected cardiac implantable electronic device (CIED) infections, their management is often challenging. AIMS: To describe our diagnostic and therapeutic practices for suspected CIED infection, and to compare them with European Heart Rhythm Association (EHRA) guidelines. METHODS: Patients hospitalized in the tertiary care Nancy University Hospital for suspected CIED infection from 2014 to 2019 were included retrospectively. We applied the EHRA classification of CIED infection, and compared diagnostic and therapeutic management with the EHRA guidelines. RESULTS: Among 184 patients (mean age 72.3±12.4 years), 137 had a proven infection of the lead (by transthoracic echocardiography/transoesophageal echocardiography, 18F-fluorodesoxyglucose positron emission tomography/computed tomography or positive culture of the lead) or an isolated pocket infection without proof of lead infection, and 47 had no proof of CIED infection. According to the EHRA classification, CIED infection was considered as definite in 145 patients and possible in 31 and was excluded in eight patients. Regarding recommended diagnostic procedures, blood cultures were performed in 90.8%, transthoracic echocardiography in 97.8%, transoesophageal echocardiography in 85.9%, 18F-fluorodesoxyglucose positron emission tomography/computed tomography in 50.5% and imaging for embolisms in 78.3% of the patients. Compared with therapeutic recommendations for the 145 cases of definite CIED infection, device removal was performed in 96 patients (66.2%) and antibiotic therapy was prescribed in 130 (89.7%), with a duration equal to or longer than that recommended in 105 (72.4%) of the patients. CONCLUSION: This study underlines the difficulties in following theoretical guidelines in daily practice, where both technical and human considerations interfere with their strict appliance.

Temporal Relationship between Atrial Fibrillation and Heart Failure Development Analysis from a Nationwide Database.

Background Atrial fibrillation (AF) and heart failure (HF) often co-exist and are closely intertwined, each condition worsening the other. The temporal relationships between these two disorders have not yet been fully explored. We aimed to address the outcomes of patients hospitalized with HF and AF based on the chronology of the onset of the two disorders. Methods From the administrative database for the whole French population, we identified 1,349,638 patients diagnosed with both AF and HF between 2010 and 2018; 956,086 of these AF patients developed HF first (prevalent HF), and 393,552 developed HF after AF (incident HF). The outcome analysis (all-cause death, cardiovascular (CV) death, ischemic stroke or hospitalization for HF) was performed with follow-up starting at the time of last event between AF or HF in the whole cohort and in 427,848 propensity score-matched patients. Results During follow-up (mean follow-up 1.6 ± 1.9 year), matched patients with prevalent HF had a higher risk of all-cause death (21.6 vs. 19.3%/year, hazard ratio (HR) 1.10, 95% CI 1.08-1.11), CV death (7.7 vs. 6.5%/year, HR 1.14, 95% CI 1.12-1.16) as well as re-hospitalization for HF (19.4 vs. 13.2%/year, HR 1.44, 95% CI 1.41-1.46) than those with incident HF. The risk for ischemic stroke was lower in prevalent HF than in incident HF (1.2 vs. 2.4%/year, HR 0.50, 95% CI 0.48-0.52). Conclusions We identified two distinct clinical entities: patients in whom HF preceded AF (prevalent HF) had higher mortality and higher risk of re-hospitalization for HF.

Epidemiological characteristics and therapeutic management of patients with chronic heart failure who use smartphones: Potential impact of a dedicated smartphone application (report from the OFICSel study).

BACKGROUND: The effectiveness of transitional care services for patients discharged from hospital after acute heart failure is challenging, especially in terms of reducing subsequent heart failure hospitalizations. The increased adoption of smartphone applications in society offers a new opportunity to interact with patients to avoid rehospitalization. Thus, electronic health (e-health) can enhance the impact of existing therapeutic education programmes. AIMS: To determine the prevalence of smartphone use among patients with chronic heart failure, and to assess the epidemiological characteristics and therapeutic management of these patients, with a broader aim of developing smartphone-based therapeutic education programmes for patients. METHODS: The French Observatoire français de l'insuffisance cardiaque et du sel (OFICSel) registry was conducted in 2017 by 300 cardiologists, and included both inpatients and outpatients who had been hospitalized for heart failure at least once in the previous 5 years. Data collection included demographic and heart failure-related variables, which were provided by the cardiologist and by the patient via a questionnaire. RESULTS: Among the 2822 patients included, 2517 completed the questionnaire. Of this total, 907 patients (36%) were smartphone users. Compared with non-users, smartphone users were younger, were more frequently men, more frequently lived in cities, had a higher educational level and were more frequently professionally active. Smartphone users less frequently had diabetes, hypertension, atrial fibrillation or ischaemic cardiopathy. Only 22% of patients were actively participating in a therapeutic education programme. CONCLUSION: Smartphones were used by more than one-third of patients with heart failure in France in 2017, underscoring the feasibility of developing a smartphone application to deliver therapeutic education to the population with chronic heart failure.

Outpatient healthcare utilization 30 days before and after hospitalization for heart failure in France: Contribution of the national healthcare database (Systèmenationaldesdonnéesdesanté).

BACKGROUND: Guidelines have been published concerning patient management after hospitalization for heart failure. The French national healthcare database (Systèmenationaldesdonnéesdesanté; SNDS) can be used to compare these guidelines with real-life practice. AIMS: To study healthcare utilization 30 days before and after hospitalization for heart failure, and the variations induced by the exclusion of institutionalized patients, who are less exposed to outpatient healthcare utilization. METHODS: We identified the first hospitalization for heart failure in 2015 of adult beneficiaries of the health insurance schemes covering 88% of the French population, who were alive 30 days after hospitalization. Outpatient healthcare utilization rates during the 30 days after hospitalization and the median times to outpatient care, together with their interquartile ranges, were described for all patients, and for a subgroup excluding institutionalized patients. RESULTS: Among the 104,984 patients included (mean age 79 years; 52% women), 74% were non-institutionalized (mean age 78 years; 47% women). The frequencies of at least one consultation after hospitalization and the median times to consultation were 69% (total sample) vs. 78% (subgroup excluding institutionalized patients) and 8 days (interquartile range 3; 16) vs. 7 days (3; 15) for general practitioners, 20% vs. 21% and 14 days (7; 23) vs. 16 days (9; 24) for cardiologists and 58% vs. 69% and 3 days (1; 9) vs. 2 days (1; 7) for nurses, with reimbursement of diuretics in 77% vs. 86%, angiotensin-converting enzyme inhibitors or angiotensin II receptor blockers in 48% vs. 55% and beta-blockers in 55% vs. 63%. Departmental variations, excluding institutionalized patients, were large: general practice consultations (interquartile range 74%; 83%), cardiology consultations (11%; 23%) and nursing care (68%; 77%). CONCLUSIONS: Low outpatient healthcare utilization rates, long intervals to first healthcare utilization and departmental variations indicate a mismatch between guidelines and real-life practice, which is accentuated when including institutionalized patients.

Epidemiological Features of Aortic Stenosis in a French Nationwide Study: 10-Year Trends and New Challenges.

Background Aortic stenosis (AS) is one of the most common forms of valvular heart disease. Our aim was to estimate the burden of AS in the hospital in France, describe patient characteristics, and evaluate the mortality rate and temporal trends. Methods and Results All patients hospitalized for AS in France between 2006 and 2016 were identified from the national hospital discharge database. Patients' sociodemographic, medical, and surgical characteristics and temporal trends were described. All AS-related deaths between 2000 and 2014 were identified using death certificates. In 2016, 26 071 patients were hospitalized for AS: 56.5% were men with an average age of 77 years. The all-cause mortality rate at 1 year postindex stay was 11%. The rate of patients hospitalized for AS increased by 59% between 2006 and 2016, reaching 38.7/100 000 person-years in 2016. This increase was most pronounced in patients aged >75 years. The number of transcatheter aortic valve implantations increased following their introduction in 2010. In 2016, 44% of patients were treated with aortic valve surgery during the index hospital stay or following year (mean age, 71.5 years), and 34% were treated with transcatheter aortic valve implantation (mean age, 83.0 years). In 2014, 6186 deaths caused by AS were identified in death certificates: 41.6% were men with an average age of 87 years. The age-standardized mortality rate increased by 5% between 2000 and 2014, reaching 8.5/100 000 person-years in 2014. Conclusions The rate of patients hospitalized for AS increased in recent years in line with the higher life expectancy and introduction of transcatheter aortic valve implantation. Mortality increased more moderately.

Patient care pathways in acute heart failure and their impact on in-hospital mortality, a French national prospective survey.

BACKGROUND: Our purpose was to describe the care pathway of patients hospitalized for acute heart failure (AHF) and investigate whether a management involving a cardiology department had an impact on in-hospital mortality. METHODS: Between June 2014 and October 2018, we included patients hospitalized for AHF in 24 French hospitals. Characteristics of the episode, patient's care pathway and outcomes were recorded on a specific assessment tool. The primary outcome was the association between patient care pathway and in-hospital mortality. The independent association between admission to a cardiology ward and in-hospital mortality was assessed through a multivariate regression model and propensity score matching. RESULTS: A total of 3677 patients, mean age of 78, were included. The in-hospital mortality rate was 8% (n = 287) and was associated on multivariate regression with advanced age, presence of sepsis, of cardiogenic shock, high New York Heart Association (NYHA) score and increased plasma creatinine level on admission. High blood pressure and admission to a cardiology department appeared as protective factors. After propensity score matching, hospitalization in a cardiology department remained a protective factor of in-hospital mortality (OR = 0.61 [0.44-0.84], p = 0.002). CONCLUSION: A hospital course of care involving a cardiology department was associated with an increase in hospital survival in AHF patients. These finding may highlight the importance of collaboration between cardiologists and other in-hospitals specialties, such as emergency physicians, in order to find the best in-hospital pathway for patients with AHF.Clinical Trial NCT03903198.

Rationale and design of the Karolinska-Rennes (KaRen) prospective study of dyssynchrony in heart failure with preserved ejection fraction.

AIMS: Heart failure with preserved ejection fraction (HFPEF) is common but not well understood. Electrical dyssynchrony in systolic heart failure is harmful. Little is known about the prevalence and the prognostic impact of dyssynchrony in HFPEF. METHODS AND RESULTS: We have designed a prospective, multicenter, international, observational study to characterize HFPEF and to determine whether electrical or mechanical dyssynchrony affects prognosis. Patients presenting with acute heart failure (HF) will be screened so as to identify 400 patients with HFPEF. Inclusion criteria will be: acute presentation with Framingham criteria for HF, left ventricular ejection fraction>or=45%, brain natriuretic peptide (BNP)>100 pg/mL or NT-proBNP>300 pg/mL. Once stabilized, 4-8 weeks after the index presentation, patients will return and undergo questionnaires, serology, ECG, and Doppler echocardiography. Thereafter, patients will be followed for mortality and HF hospitalization every 6 months for at least 18 months. Sub-studies will focus on echocardiographic changes from the acute presentation to the stable condition and on exercise echocardiography, cardiopulmonary exercise testing, and serological markers. CONCLUSION: KaRen aims to characterize electrical and mechanical dyssynchrony and to assess its prognostic impact in HFPEF. The results might improve our understanding of HFPEF and generate answers to the question whether dyssynchrony could be a target for therapy in HFPEF.

Nonischemic dilated cardiomyopathy: results of noninvasive and invasive evaluation in 310 patients and clinical significance of bundle branch block.

BACKGROUND: The survival of patients with idiopathic dilated cardiomyopathy (IDCM) at III and IV stages of New York Heart Association (NYHA) is decreased in those with a bundle branch block (BBB) compared to those without BBB. Less is known on the prognosis of patients at earlier stages of NYHA and who had a left BBB (LBBB) or right BBB (RBBB). We sought to evaluate the prevalence and the clinical significance of LBBB or RBBB in patients with IDCM and classes I and II of NYHA. METHODS: Clinical data, noninvasive, and invasive studies were consecutively collected in 310 patients, with IDCM, followed up to 4.8+/-3.7 years. RESULTS: Seventy-six patients (25%) had LBBB, 21 (7%) had RBBB, and 212 had no BBB. Patients with BBB were older than other patients (P < 0.009). Left ventricular ejection fraction (LVEF) was lower in LBBB than in RBBB and other patients (P < 0.05). Syncope was more frequent in BBB than in absence (P < 0.05). Incidence of spontaneous ventricular tachycardia (VT) and atrial fibrillation, VT induction, total cardiac events, and sudden death were similar in the presence or absence of BBB. Deaths by heart failure and heart transplantations tended to be more frequent in BBB than in absence. CONCLUSIONS: LBBB was present in 25% of patients with IDCM; RBBB was rare. Patients with BBB were older and had more frequent syncope than patients without BBB; LVEF was lower in LBBB than in RBBB or in absence of BBB. BBB did not increase the risk of spontaneous VT, VT induction, or sudden death, and tended to increase deaths by heart failure and the indications of heart transplantation.
