Cardiogenic shock and chronic kidney disease: Dangerous liaisons.

BACKGROUND: Chronic kidney disease (CKD) is one of the leading causes of death worldwide, closely interrelated with cardiovascular diseases, ultimately leading to the failure of both organs - the so-called "cardiorenal syndrome". Despite this burden, data related to cardiogenic shock outcomes in CKD patients are scarce. METHODS: FRENSHOCK (NCT02703038) was a prospective registry involving 772 patients with cardiogenic shock from 49 centres. One-year outcomes (rehospitalization, death, heart transplantation, ventricular assist device) were analysed according to history of CKD at admission and were adjusted on independent predictive factors. RESULTS: CKD was present in 164 of 771 patients (21.3%) with cardiogenic shock; these patients were older (72.7 vs. 63.9years) and had more comorbidities than those without CKD. CKD was associated with a higher rate of all-cause mortality at 1month (36.6% vs. 23.2%; hazard ratio 1.39, 95% confidence interval 1.01-1.9; P=0.04) and 1year (62.8% vs. 40.5%, hazard ratio 1.39, 95% confidence interval 1.09-1.77; P<0.01). Patients with CKD were less likely to be treated with norepinephrine/epinephrine or undergo invasive ventilation or receive mechanical circulatory support, but were more likely to receive renal replacement therapy (RRT). RRT was associated with a higher risk of all-cause death at 1month and 1year regardless of baseline CKD status. CONCLUSIONS: Cardiogenic shock and CKD are frequent "cross-talking" conditions with limited therapeutic options, resulting in higher rates of death at 1month and 1year. RRT is a strong predictor of death, regardless of preexisting CKD. Multidisciplinary teams involving cardiac and kidney physicians are required to provide integrated care for patients with failure of both organs.

Sex disparities in cardiogenic shock: Insights from the FRENSHOCK registry.

BACKGROUND: Cardiogenic shock (CS) is the most severe form of acute heart failure. Discrepancies have been reported between sexes regarding delays, pathways and invasive strategies in CS complicating acute myocardial infarction. However, effect of sex on the prognosis of unselected CS remains controversial. OBJECTIVES: The aim was to analyze the impact of sex on aetiology, management and prognosis of CS. METHODS: The FRENSHOCK registry included all CS admitted in 49 French Intensive Care Units (ICU) and Intensive Cardiac Care Units (ICCU) between April and October 2016. RESULTS: Among the 772 CS patients included, 220 were women (28.5%). Women were older, less smokers, with less history of ischemic cardiac disease (20.5% vs 33.6%) than men. At admission, women presented less cardiac arrest (5.5 vs 12.2%), less mottling (32.5 vs 41.4%) and higher LVEF (30 ± 14 vs 25 ± 13%). Women were more often managed via emergency department while men were directly admitted at ICU/ICCU. Ischemia was the most frequent trigger irrespective of sex (36.4% in women vs 38.2%) but women had less coronary angiogram and PCI (45.9% vs 54% and 24.1 vs 31.3%, respectively). We found no major difference in medication and organ support. Thirty-day mortality (26.4 vs 26.5%), transplant or permanent assist device were similar in both sexes. CONCLUSION: Despite some more favorable parameters in initial presentation and no significant difference in medication and support, women shared similar poor prognosis than men. Further analysis is required to cover the lasting gap in knowledge regarding sex specificities to distinguish between differences and inequalities. NCT02703038.

Optimal Heart Failure Medical Therapy and Mortality in Survivors of Cardiogenic Shock: Insights From the FRENSHOCK Registry.

BACKGROUND: The effects of pharmacological therapy on cardiogenic shock (CS) survivors have not been extensively studied. Thus, this study investigated the association between guideline-directed heart failure (HF) medical therapy (GDMT) and one-year survival rate in patients who are post-CS. METHODS AND RESULTS: FRENSHOCK (French Observatory on the Management of Cardiogenic Shock in 2016) registry was a prospective multicenter observational survey, conducted in metropolitan French intensive care units and intensive cardiac care units. Of 772 patients, 535 patients were enrolled in the present analysis following the exclusion of 217 in-hospital deaths and 20 patients with missing medical records. Patients with triple GDMT (beta-blockers, renin-angiotensin system inhibitors, and mineralocorticoid receptor antagonists) at discharge (n=112) were likely to have lower left ventricular ejection fraction on admission and at discharge compared with those without triple GDMT (n=423) (22% versus 28%, P<0.001 and 29% versus 37%, P<0.001, respectively). In the overall cohort, the one-year mortality rate was 23%. Triple GDMT prescription was significantly associated with a lower one-year all-cause mortality compared with non-triple GDMT (adjusted hazard ratio 0.44 [95% CI, 0.19-0.80]; P=0.007). Similarly, 2:1 propensity score matching and inverse probability treatment weighting based on the propensity score demonstrated a lower incidence of one-year mortality in the triple GDMT group. As the number of HF drugs increased, a stepwise decrease in mortality was observed (log rank; P<0.001). CONCLUSIONS: In survivors of CS, the one-year mortality rate was significantly lower in those with triple GDMT. Therefore, this study suggests that intensive HF therapy should be considered in patients following CS.

Cardiogenic Shock in Idiopathic Dilated Cardiomyopathy Patients: Red Flag for Myocardial Decline.

Idiopathic dilated cardiomyopathy (IDCM) is one of the most common forms of nonischemic cardiomyopathy worldwide, possibly leading to cardiogenic shock (CS). Despite this heavy burden, the outcomes of CS in IDCM are poorly reported. Based on a large registry of unselected CS, our aim was to shed light on the 1-year outcomes after CS in patients with and without IDCM. FRENSHOCK was a prospective registry including 772 patients with CS from 49 centers. The 1-year outcomes (rehospitalizations, mortality, heart transplantation [HTx], ventricular assist devices [VAD]) were analyzed and adjusted on independent predictive factors. Within 772 CS included, 78 occurred in IDCM (10.1%). Patients with IDCM had more frequent history of chronic kidney failure and implantable cardioverter-defibrillator implantation. No difference was found in 1-month all-cause mortality between groups (28.2 vs 25.8%for IDCM and others, respectively; adjusted hazard ratio 1.14 [0.73 to 1.77], p = 0.57). Patients without IDCM were more frequently treated with noninvasive ventilation and intra-aortic balloon pump. At 1 year, IDCM led to higher rates of death or cardiovascular rehospitalizations (adjusted odds ratio 4.77 [95% confidence interval 1.13 to 20.1], p = 0.03) and higher rates of HTx or VAD for patients aged <65 years (adjusted odds ratio 2.68 [1.21 to 5.91], p = 0.02). In conclusion, CS in IDCM is a very common scenario and is associated with a higher rate of 1-year death or cardiovascular rehospitalizations and a more frequent recourse to HTx or VAD for patients aged <65 years, encouraging the consideration of it as a red flag for myocardial decline and urging for a closer follow-up and earlier evaluation for advanced heart failure therapies.

Mottling as a prognosis marker in cardiogenic shock.

AIMS: Impact of skin mottling has been poorly studied in patients admitted for cardiogenic shock. This study aimed to address this issue and identify determinants of 30-day and 1-year mortality in a large cardiogenic shock cohort of all etiologies. METHODS AND RESULTS: FRENSHOCK is a prospective multicenter observational registry conducted in French critical care units between April and October, 2016. Among the 772 enrolled patients (mean age 65.7 ± 14.9 years; 71.5% male), 660 had skin mottling assessed at admission (85.5%) with almost 39% of patients in cardiogenic shock presenting mottling. The need for invasive respiratory support was significantly higher in patients with mottling (50.2% vs. 30.1%, p < 0.001) and likewise for the need for renal replacement therapy (19.9% vs. 12.4%, p = 0.09). However, the need for mechanical circulatory support was similar in both groups. Patients with mottling at admission presented a higher length of stay (19 vs. 16 days, p = 0.033), a higher 30-day mortality rate (31% vs. 23.3%, p = 0.031), and also showed significantly higher mortality at 1-year (54% vs. 42%, p = 0.003). The subgroup of patients in whom mottling appeared during the first 24 h after admission had the worst prognosis at 30 days. CONCLUSION: Skin mottling at admission in patients with cardiogenic shock was statistically associated with prolonged length of stay and poor outcomes. As a perfusion-targeted resuscitation parameter, mottling is a simple, clinical-based approach and may thus help to improve and guide immediate goal-directed therapy to improve cardiogenic shock patients' outcomes.

One-year outcomes in cardiogenic shock triggered by supraventricular tachycardia: an analysis of the FRENSHOCK multicenter prospective registry.

Background: Cardiogenic shock (CS) is the most severe form of heart failure (HF), resulting in high early and long-term mortality. Characteristics of CS secondary to supraventricular tachycardia (SVT) are poorly reported. Based on a large registry of unselected CS, we aimed to compare 1-year outcomes between SVT-triggered and non-SVT-triggered CS. Methods: FRENSHOCK is a French prospective registry including 772 CS patients from 49 centers. For each patient, the investigator could report 1-3 CS triggers from a pre-established list (ischemic, mechanical complications, ventricular/supraventricular arrhythmia, bradycardia, iatrogenesis, infection, non-compliance, and others). In this study, 1-year outcomes [rehospitalizations, mortality, heart transplantation (HTx), ventricular assist devices (VAD)] were analyzed and adjusted for independent predictive factors. Results: Among 769 CS patients included, 100 were SVT-triggered (13%), of which 65 had SVT as an exclusive trigger (8.5%). SVT-triggered CS patients exhibited a higher proportion of male individuals with a more frequent history of cardiomyopathy or chronic kidney disease and more profound CS (biventricular failure and multiorgan failure). At 1 year, there was no difference in all-cause mortality (43% vs. 45.3%, adjusted HR 0.9 (95% CI 0.59-1.39), p = 0.64), need for HTx or VAD [10% vs. 10%, aOR 0.88 (0.41-1.88), p = 0.74], or rehospitalizations [49.4% vs. 44.4%, aOR 1.24 (0.78-1.98), p = 0.36]. Patients with SVT as an exclusive trigger presented more 1-year rehospitalizations [52.8% vs. 43.3%, aOR 3.74 (1.05-10.5), p = 0.01]. Conclusion: SVT is a frequent trigger of CS alone or in association in more than 10% of miscellaneous CS cases. Although SVT-triggered CS patients were more comorbid with more pre-existing cardiomyopathies and HF incidences, they presented similar rates of mortality, HTx, and VAD at 1 year, arguing for a better overall prognosis.

Cardiogenic shock in adults with congenital heart disease: Insights from the FRENSHOCK registry.

BACKGROUND: Data on cardiogenic shock in adults with congenital heart disease (ACHD) are scarce. AIM: We sought to describe cardiogenic shock in ACHD patients in a nationwide cardiogenic shock registry. METHODS: From the multicentric FRENSHOCK registry (772 patients with cardiogenic shock from 49 French centres between April and October 2016), ACHD patients were compared with adults without congenital heart disease (non-ACHD). The primary outcome was defined by all-cause mortality, chronic ventricular assist device or heart transplantation at 1year. RESULTS: Out of the 772 patients, seven (0.9%) were ACHD, who were younger (median age: 56 vs. 67years), had fewer cardiovascular risk factors, such as hypertension (14.3% vs. 47.5%) and diabetes (14.3% vs. 28.3%), and no previous ischaemic cardiopathy (0 vs. 61.5%). Right heart catheterization (57.1% vs. 15.4%), pacemakers (28.6% vs. 4.6%) and implantable cardioverter-defibrillators (28.6% vs. 4.8%) were indicated more frequently in the management of ACHD patients compared with non-ACHD patients, whereas temporary mechanical circulatory support (0 vs. 18.7%) and invasive mechanical ventilation (14.3% vs. 38.1%) were less likely to be used in ACHD patients. At 1year, the primary outcome occurred in 85.7% (95% confidence interval: 42.1-99.6) ACHD patients and 52.3% (95% confidence interval: 48.7-55.9) non-ACHD patients. Although 1-year mortality was not significantly different between ACHD patients (42.9%) and non-ACHD patients (45.4%), ventricular assist devices and heart transplantation tended to be more frequent in the ACHD group. CONCLUSIONS: Cardiogenic shock in ACHD patients is rare, accounting for only 0.9% of an unselected cardiogenic shock population. Despite being younger and having fewer co-morbidities, the prognosis of ACHD patients with cardiogenic shock remains severe, and is similar to that of other patients.

Acute heart failure in elderly patients admitted to the emergency department with acute dyspnea: a multimarker approach diagnostic study.

BACKGROUND AND IMPORTANCE: Diagnosing acute heart failure (AHF) is difficult in elderly patients presenting with acute dyspnea to the emergency department. OBJECTIVES: To assess the diagnostic accuracy of NT-proBNP, high-sensitivity cardiac troponin-I (Hs-cTnI), soluble ST2 (ST2), galectin-3 and CD146 alone and in combination for diagnosing AHF in elderly patients presenting with acute dyspnea to the emergency department. DESIGN, SETTINGS AND PARTICIPANTS: This was a prospective, multicenter study performed between September 2016 and January 2020, including elderly patients presenting with acute dyspnea to the emergency department of 6 French hospitals. INTERVENTION: Measurement of NT-proBNP, hs-cTnI, ST2, galectin-3 and CD146. OUTCOME MEASURE AND ANALYSIS: The reference standard, AHF, was adjudicated by two independent physicians based on ED and hospitalization clinical, biological (excluding biomarkers), radiological and echocardiography data (performed by a cardiologist in the cardiology department specifically for this study). Three exploratory methods (two using a cross-sectional approach with logistic regression and counting all biomarker combinations, and one using a sequential approach with gray zone optimizations) were applied to create comprehensive combinations of the 5 biomarkers for measuring diagnostic accuracy. MAIN RESULTS: Two hundred thirty-eight patients (median age of 85 years, IQR = 8) were analyzed, and 110 (46%) were diagnosed with AHF. The accuracies of NT-proBNP, CD146, hs-cTnI, galectin-3, and ST2 were 0.72 [95% confidence interval (CI) 0.66-0.77], 0.63 (95% CI 0.57-0.69), 0.59 (95% CI 0.53-0.65), 0.55 (95% CI 0.49-0.61) and 0.51 (95% CI 0.45-0.57), respectively. Regardless of the approach used or how the 5 biomarkers were combined, the best accuracy for diagnosing AHF (0.73, 95% CI 0.67-0.78) did not differ from that of NT-proBNP alone. CONCLUSION: In this study, NT-proBNP alone exhibited the best diagnostic accuracy for diagnosing AHF in elderly patients presenting with acute dyspnea to the emergency departments. None of the other biomarkers alone or combined improved the accuracy compared to NT-proBNP, which is the only biomarker to use in this setting.

Characteristics, management, and outcomes of active cancer patients with cardiogenic shock.

AIMS: Characteristics, management, and outcomes of patients with active cancer admitted for cardiogenic shock remain largely unknown. This study aimed to address this issue and identify the determinants of 30-day and 1-year mortality in a large cardiogenic shock cohort of all aetiologies. METHODS AND RESULTS: FRENSHOCK is a prospective multicenter observational registry conducted in French critical care units between April and October 2016. 'Active cancer' was defined as a malignancy diagnosed within the previous weeks with planned or ongoing anticancer therapy. Among the 772 enrolled patients (mean age 65.7 ± 14.9 years; 71.5% male), 51 (6.6%) had active cancer. Among them, the main cancer types were solid cancers (60.8%), and hematological malignancies (27.5%). Solid cancers were mainly urogenital (21.6%), gastrointestinal (15.7%), and lung cancer (9.8%). Medical history, clinical presentation, and baseline echocardiography were almost the same between groups. In-hospital management significantly differed: patients with cancers received more catecholamines or inotropes (norepinephrine 72% vs. 52%, P = 0.005 and norepinephrine-dobutamine combination 64.7% vs. 44.5%, P = 0.005), but had less mechanical circulatory support (5.9% vs. 19.5%, P = 0.016). They presented a similar 30-day mortality rate (29% vs. 26%) but a significantly higher mortality at 1-year (70.6% vs. 45.2%, P < 0.001). In multivariable analysis, active cancer was not associated with 30-day mortality but was significantly associated with 1-year mortality in 30-day survivors [HR 3.61 (1.29-10.11), P = 0.015]. CONCLUSION: Active cancer patients accounted for almost 7% of all cases of cardiogenic shock. Early mortality was the same regardless of active cancer or not, whereas long-term mortality was significantly increased in patients with active cancer.

Profiles of patients referred to specialized palliative care from the cardiology department at a university hospital: an 11-year longitudinal retrospective study.

BACKGROUND: Although the majority of patients with cardiovascular diseases (CVD) have a significant symptom burden and progressive course towards the end of life, only a small proportion of patients currently receive palliative care. The current referral practices to palliative care from the cardiology department need to be scrutinized. The current study aimed to examine: 1) the clinical profile; 2) time between referral to palliative care and death; and 3) place of death for CVD patients who were referred to palliative care from a cardiology department. METHODS: This retrospective descriptive study included all patients who were referred to the mobile palliative care team from the cardiology unit in the University Hospital of Besançon in France between January 2010 and December 2020. Information was extracted from the medical hospital files. RESULTS: A total of 142 patients were included, of whom 135 (95%) died. The mean age at the time of death was 76±14 years. The median time between referral to palliative care and death was 9 days. Most patients had chronic heart failure (54%). A total of 17 patients (13%) died at home. CONCLUSIONS: This study showed that referral of patients to palliative care from the cardiology department is suboptimal and a large proportion of patients die in the hospital setting. Further prospective studies are warranted to investigate whether these dispositions correspond to patients' wishes and end-of-life care needs, and should investigate how the integration of palliative care into the care of cardiovascular patients can be improved.

Perceptions and satisfaction of patients with chronic heart failure when using a remote monitoring web application named Satelia® Cardio.

INTRODUCTION: The use of telehealth, such as remote patient monitoring (RPM), for chronic heart failure (CHF) impacts patient pathways. Patient-centricity in chronic disease management is valuable. Even though RPM is recommended in practice, the evaluation of patient satisfaction has been limited to date. The objective of this study was to assess the perceptions and satisfaction of patients with CHF when using RPM. METHODS: A voluntary declarative survey was conducted with users of Satelia® Cardio, an RPM web application which was included in an experimental model program in France funded by the ETAPES program initiative sponsored by the French Ministry of Health. Monitoring was based on patient-reported outcomes (seven questions on symptoms, one question on weight) which were answered online (digitally literate patients) or by phone with a nurse (patients with poor digital literacy). The survey included questions on perceived usefulness, ease of use and impact on quality of life (QoL). RESULTS: Overall, 87% of the 825 patients were satisfied with having their CHF digitally monitored. Patients found that the application was easy to use (94%), problem free (95%), provided well-timed notifications (98%), easily accessible (96.5%), understandable (89%), and did not require an unreasonable amount of time to answer questions (99%). Most patients felt that RPM helped physicians provide better care during their follow-ups (70%, mean score: 7.98/10) and 45% of the digitally literate patients indicated an improved QoL. CONCLUSION: Poor digitally literate patients may need human-based or assisted RPM. Patients monitored daily for CHF through RPM expressed strong satisfaction and acceptance.

One-year outcomes in cardiogenic shock triggered by ventricular arrhythmia: An analysis of the FRENSHOCK multicenter prospective registry.

Background: Cardiogenic shock (CS) is a life-threatening condition carrying poor prognosis, potentially triggered by ventricular arrhythmia (VA). Whether the occurrence of VA as trigger of CS worsens the prognosis compared to non-VA triggers  remains  unclear.  The  aim  of  this  study  was  to  evaluate  1-year  outcomes [mortality, heart transplantation, ventricular assist devices (VAD)] between VA-triggered and non-VA-triggered CS. Methods: FRENSHOCK is a prospective multicenter registry including 772 CS patients from 49 centers. One to three triggers can be identified in the registry (ischemic, mechanical complications, ventricular/supraventricular arrhythmia, bradycardia, iatrogenesis, infection, non-compliance). Baseline characteristics, management and 1-year outcomes were analyzed according to the VA-trigger in the CS population. Results: Within 769 CS patients included, 94 were VA-triggered (12.2%) and were compared to others. At 1 year, although there was no mortality difference [42.6 vs. 45.3%, HR 0.94 (0.67-1.30), p = 0.7], VA-triggered CS resulted in more heart transplantations and VAD (17 vs. 9%, p = 0.02). Into VA-triggered CS group, though there was no 1-year mortality difference between ischemic and non-ischemic cardiomyopathies [42.5 vs. 42.6%, HR 0.97 (0.52-1.81), p = 0.92], non-ischemic cardiomyopathy led to more heart transplantations and VAD (25.9 vs. 5%, p = 0.02). Conclusion: VA-triggered CS did not show higher mortality compared to other triggers but resulted in more heart transplantation and VAD at 1 year, especially in non-ischemic cardiomyopathy, suggesting the need for earlier evaluation by advanced heart failure specialized team for a possible indication of mechanical circulatory support or heart transplantation.

Feasibility and accuracy of linking a heart failure registry to the national claims database using indirect identifiers.

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.

Systematic screening for advanced liver fibrosis in patients with coronary artery disease: The CORONASH study.

Although coronary artery disease (CAD) and advanced liver fibrosis (AdLF) are commonly associated in patients with non-alcoholic fatty liver disease (NAFLD), the prevalence of AdLF and the diagnostic performance of non-invasive fibrosis tests (NITs) in CAD patients remains unknown. We aimed to prospectively screen for AdLF in patients with documented CAD using NITs and Fibroscan. High and intermediate zones of NITs were combined to define AdLF. AdLF was suspected whenever APRI ≥ 0.5, Forns index ≥ 4.2, NAFLD fibrosis score (NFS) ≥ -1.455/0.12 for age

Baseline characteristics, management, and predictors of early mortality in cardiogenic shock: insights from the FRENSHOCK registry.

AIMS: Published data on cardiogenic shock (CS) are scarce and are mostly focused on small registries of selected populations. The aim of this study was to examine the current CS picture and define the independent correlates of 30 day mortality in a large non-selected cohort. METHODS AND RESULTS: FRENSHOCK is a prospective multicentre observational survey conducted in metropolitan French intensive care units and intensive cardiac care units between April and October 2016. There were 772 patients enrolled (mean age 65.7 ± 14.9 years; 71.5% male). Of these patients, 280 (36.3%) had ischaemic CS. Organ replacement therapies (respiratory support, circulatory support or renal replacement therapy) were used in 58.3% of patients. Mortality at 30 days was 26.0% in the overall population (16.7% to 48.0% depending on the main cause and first place of admission). Multivariate analysis showed that six independent factors were associated with a higher 30 day mortality: age [per year, odds ratio (OR) 1.06, 95% confidence interval (CI): 1.04-1.08], diuretics (OR 1.74, 95% CI: 1.05-2.88), circulatory support (OR 1.92, 95% CI: 1.12-3.29), left ventricular ejection fraction <30% (OR 2.15, 95% CI: 1.40-3.29), norepinephrine (OR 2.55, 95% CI: 1.69-3.84), and renal replacement therapy (OR 2.72, 95% CI: 1.65-4-49). CONCLUSIONS: Non-ischaemic CS accounted for more than 60% of all cases of CS. CS is still associated with significant but variable short-term mortality according to the cause and first place of admission, despite frequent use of haemodynamic support, and organ replacement therapies.

Early and short-term intensive management after discharge for patients hospitalized with acute heart failure: a randomized study (ECAD-HF).

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.

Impact of Midregional N-Terminal Pro-Atrial Natriuretic Peptide and Soluble Suppression of Tumorigenicity 2 Levels on Heart Rhythm in Patients Treated With Catheter Ablation for Atrial Fibrillation: The Biorhythm Study.

Background We assessed the impact of preprocedural plasma levels of MRproANP (midregional N-terminal pro-atrial natriuretic peptide) and sST2 (soluble suppression of tumorigenicity 2) on recurrence of atrial fibrillation (AF) at 1 year after catheter ablation of AF. Methods and Results This was a prospective, multicenter, observational study including patients undergoing catheter ablation of AF. MRproANP and sST2 were measured in a peripheral venous blood preprocedure, and MRproANP was assessed in the right and left atrial blood during ablation. The primary end point was recurrent AF between 3 and 12 months postablation, defined as a documented (>30 seconds) episode of AF, flutter, or atrial tachycardia. We included 106 patients from December 2017 to March 2019; 105 had complete follow-up, and the mean age was 63 years with 74.2% males. Overall, 34 patients (32.1%) had recurrent AF. In peripheral venous blood, MRproANP was significantly higher in patients with recurrent AF (median, 192.2; [quartile 1-quartile 3, 155.9-263.9] versus 97.1 [60.9-150.7] pmol/L; P<0.0001), as was sST2 (median, 30.3 [quartile 1-quartile 3, 23.3-39.3] versus 23.4 [95% CI, 17.4-33.0] ng/mL; P=0.0033). In the atria, MRproANP was significantly higher than in peripheral blood and was higher during AF than during sinus rhythm. Receiver operating characteristic curve analysis identified a threshold of MRproANP>107.9 pmol/L to predict AF recurrence at 1 year and a threshold of >26.7 ng/mL for sST2. By multivariate analysis, MRproANP>107.9 pmol/L was the only independent predictor of recurrent AF (OR, 24.27; 95% CI, 4.23-139.18). MRproANP<107.9 pmol/L identified subjects at very low risk of recurrence (negative predictive value >95%).
