RESUMO

AIMS: There is a lack of specific studies assessing the impact of natriuretic peptide monitoring in the post-discharge management of patients with heart failure (HF) and preserved ejection fraction (HFpEF), throughout the vulnerable phase following acute HF hospitalization. The NICE study aims to assess the clinical benefit of incorporating N-terminal pro-B-type natriuretic peptide (NT-proBNP) into the post-discharge management of HFpEF patients. METHODS AND RESULTS: Individuals admitted with HFpEF (left ventricular ejection fraction >50%) were included in a multicentre randomized controlled study employing an open-label design with event blinding (NCT02807168). Upon discharge, 157 patients were randomly allocated to either NT-proBNP monitoring (n = 79) or no access to NT-proBNP (control group, n = 78) during pre-scheduled visits at 2, 4 and 12 weeks. Clinical endpoints were evaluated at 6 months. The primary endpoint of HF rehospitalizations occurred in 12.1% patients, without significant differences observed between the NT-proBNP monitoring group (12.8%) and the control group (11.4%) (hazard ratio [HR] 1.15, 95% confidence interval [CI] 0.47-2.81, p = 0.760). Regarding secondary endpoints, the NT-proBNP monitoring group demonstrated a significantly lower risk of death (1.3% vs. 10.1%; HR 0.12, 95% CI 0.02-0.09), whereas non-HF hospitalizations (12.8% vs. 19.0%, p = 0.171) and any adverse clinical event (26.9% vs. 36.7%, p = 0.17) did not reach statistical significance. Awareness of NT-proBNP levels were associated with higher doses of diuretics and renin-angiotensin system inhibitors (angiotensin-converting enzyme inhibitors/angiotensin II receptor blockers) in the NT-proBNP monitoring group. CONCLUSIONS: Post-discharge monitoring of NT-proBNP in HFpEF patients did not exhibit an association with reduced rates of HF hospitalization in this study. Nonetheless, it appears to enhance global clinical management by optimizing medical therapies and contributing to improved overall survival.

RESUMO

BACKGROUND: Tricuspid regurgitation (TR) is a prevalent condition inside valvular heart disease (VHD) with relevant prognosis implications. However, concordance between real management in clinical practice and invasive treatment recommendations of European Society of Cardiology (ESC) guidelines is unknown. METHODS: A substudy of ESC VHD II survey was performed to evaluate the real treatment of TR compared to the clinical ESC guidelines recommendations published in 2012, 2017 and 2021 was performed. TR cases with surgical indication were divided in 3 groups: 1: severe isolated TR without previous left VHD; 2: moderate/severe TR and concomitant severe left VHD; 3: severe TR plus previous left VHD surgery. RESULTS: Of 902 patients assessed, 123 had significant TR. Fifty (41%) cases demonstrated ESC guidelines 2012-2017 Class I or IIa recommendations for invasive treatment: 9(18%) of group 1, 37(74%) of group 2 and 4(8%) of group 3. Surgery was performed in 24 patients (48%); 1 in group 1(4%), 22 in group 2(92%) and 1 in group 3(4%). Overall concordance was 48% (group 1: 11%; group 2: 59%; group 3: 25%). Regarding the 2021 ESC guidelines only one patient changed groups with an overall concordance of 47% (group 1: 10%; group 2: 59%; group 3: 25%). CONCLUSION: Concordance between 2012, 2017 and 2021 ESC guidelines recommendations and clinical practice for TR surgical intervention is low, especially in those without concomitant severe left VHD. These results suggest the need to improve further guideline implementation and alternative treatments, such as percutaneous, which could resolve potential discrepancies in those clinical scenarios.

RESUMO

Despite the efforts made to improve the care of cardiogenic shock (CS) patients, including the development of mechanical circulatory support (MCS), the prognosis of these patients continues to be poor. In this context, CS code initiatives arise, based on providing adequate, rapid, and quality care to these patients. In this multidisciplinary document we try to justify the need to implement the SC code, defining its structure/organization, activation criteria, patient flow according to care level, and quality indicators. Our specific purposes are: a) to present the peculiarities of this condition and the lessons of infarction code and previous experiences in CS; b) to detail the structure of the teams, their logistics and the bases for the management of these patients, the choice of the type of MCS, and the moment of its implantation, and c) to address challenges to SC code implementation, including the uniqueness of the pediatric SC code. There is an urgent need to develop protocolized, multidisciplinary, and centralized care in hospitals with a large volume and experience that will minimize inequity in access to the MCS and improve the survival of these patients. Only institutional and structural support from the different administrations will allow optimizing care for CS.

RESUMO

Device-related thrombus (DRT) after left atrial appendage (LAA) closure is infrequent but correlates with an increased risk of thromboembolism. Therefore, the search for DRT predictors is a topic of interest. In the literature, multivariable methods have been used achieving non-consistent results, and to the best of our knowledge, machine learning techniques have not been used yet for thrombus detection after LAA occlusion. Our aim is to compare both methodologies with respect to predictive power and the search for predictors of DRT. To this end, a multicenter study including 1150 patients who underwent LAA closure was analyzed. Two lines of experiments were performed: with and without resampling. Multivariate and machine learning methodologies were applied to both lines. Predictive power and the extracted predictors for all experiments were gathered. ROC curves of 0.5446 and 0.7974 were obtained for multivariate analysis and machine learning without resampling, respectively. However, the resampling experiment showed no significant difference between them (0.52 vs. 0.53 ROC AUC). A difference between the predictors selected was observed, with the multivariable methodology being more stable. These results question the validity of predictors reported in previous studies and demonstrate their disparity. Furthermore, none of the techniques analyzed is superior to the other for these data.

RESUMO

Introduction and Objectives: Most multi-biomarker strategies in acute heart failure (HF) have only measured biomarkers in a single-point time. This study aimed to evaluate the prognostic yielding of NT-proBNP, hsTnT, Cys-C, hs-CRP, GDF15, and GAL-3 in HF patients both at admission and discharge. Methods: We included 830 patients enrolled consecutively in a prospective multicenter registry. Primary outcome was 12-month mortality. The gain in the C-index, calibration, net reclassification improvement (NRI), and integrated discrimination improvement (IDI) was calculated after adding each individual biomarker value or their combination on top of the best clinical model developed in this study (C-index 0.752, 0.715-0.789) and also on top of 4 currently used scores (MAGGIC, GWTG-HF, Redin-SCORE, BCN-bioHF). Results: After 12-month, death occurred in 154 (18.5%) cases. On top of the best clinical model, the addition of NT-proBNP, hs-CRP, and GDF-15 above the respective cutoff point at admission and discharge and their delta during compensation improved the C-index to 0.782 (0.747-0.817), IDI by 5% (p < 0.001), and NRI by 57% (p < 0.001) for 12-month mortality. A 4-risk grading categories for 12-month mortality (11.7, 19.2, 26.7, and 39.4%, respectively; p < 0.001) were obtained using combination of these biomarkers. Conclusion: A model including NT-proBNP, hs-CRP, and GDF-15 measured at admission and discharge afforded a mortality risk prediction greater than our clinical model and also better than the most currently used scores. In addition, this 3-biomarker panel defined 4-risk categories for 12-month mortality.

RESUMO

BACKGROUND: Efficient and early triage of hospitalized Covid-19 patients to detect those with higher risk of severe disease is essential for appropriate case management. METHODS: We trained, validated, and externally tested a machine-learning model to early identify patients who will die or require mechanical ventilation during hospitalization from clinical and laboratory features obtained at admission. A development cohort with 918 Covid-19 patients was used for training and internal validation, and 352 patients from another hospital were used for external testing. Performance of the model was evaluated by calculating the area under the receiver-operating-characteristic curve (AUC), sensitivity and specificity. RESULTS: A total of 363 of 918 (39.5%) and 128 of 352 (36.4%) Covid-19 patients from the development and external testing cohort, respectively, required mechanical ventilation or died during hospitalization. In the development cohort, the model obtained an AUC of 0.85 (95% confidence interval [CI], 0.82 to 0.87) for predicting severity of disease progression. Variables ranked according to their contribution to the model were the peripheral blood oxygen saturation (SpO2)/fraction of inspired oxygen (FiO2) ratio, age, estimated glomerular filtration rate, procalcitonin, C-reactive protein, updated Charlson comorbidity index and lymphocytes. In the external testing cohort, the model performed an AUC of 0.83 (95% CI, 0.81 to 0.85). This model is deployed in an open source calculator, in which Covid-19 patients at admission are individually stratified as being at high or non-high risk for severe disease progression. CONCLUSIONS: This machine-learning model, applied at hospital admission, predicts risk of severe disease progression in Covid-19 patients.

RESUMO

BACKGROUND: The evidence for the efficacy of glucocorticoids combined with tocilizumab (TCZ) in COVID-19 comes from observational studies or subgroup analysis. Our aim was to compare outcomes between hospitalized COVID-19 patients who received high-dose corticosteroid pulse therapy and TCZ and those who received TCZ. METHODS: A retrospective single-center study was performed on consecutive hospitalized patients with severe COVID-19 between 1 March and 23 April 2020. Patients treated with either TCZ (400-600 mg, one to two doses) and methylprednisolone pulses (MPD-TCZ group) or TCZ alone were analyzed for the occurrence of a combined endpoint of death and need for invasive mechanical ventilation during admission. The independence of both treatment groups was tested using machine learning classifiers, and relevant variables that were potentially different between the groups were measured through a mean decrease accuracy algorithm. RESULTS: An earlier date of admission was significantly associated with worse outcomes regardless of treatment type. Twenty patients died (27.0%) in the TCZ group, and 33 (44.6%) died or required intubation (n = 74), whereas in the MPD-TCZ group, 15 (11.0%) patients died and 29 (21.3%) patients reached the combined endpoint (n = 136; p = 0.006 and p < 0.001, respectively). Machine learning methodology using a random forest classifier confirmed significant differences between the treatment groups. CONCLUSIONS: MPD and TCZ improved outcomes (death and invasive mechanical ventilation) among hospitalized COVID-19 patients, but confounding variables such as the date of admission during the COVID-19 pandemic should be considered in observational studies.

RESUMO

OBJECTIVES: Cardiac surgery or catheter interventions are nowadays commonly performed to reduce volume loading of the right ventricle in adults with congenital heart disease. However, little is known, on the effect of such procedures on pre-existing tricuspid regurgitation (TR). We assessed the potential reduction in the severity of TR after atrial septal defect (ASD) closure and pulmonic valve replacement (PVR). METHODS: Demographics, clinical and echocardiographic characteristics of consecutive patients undergoing ASD closure or PVR between 2005 and 2014 at a single centre who had at least mild preoperative TR were collected and analysed. RESULTS: Overall, 162 patients (mean age at intervention 41.6±16.1 years, 38.3% male) were included: 101 after ASD closure (61 transcatheter vs 40 surgical) and 61 after PVR (3 transcatheter vs 58 surgical). Only 11.1% received concomitant tricuspid valve surgery (repair). There was significant reduction in the severity of TR in the overall population, from 38 (23.5%) patients having moderate or severe TR preoperatively to only 11 (6.8%) and 20 (12.3%) at 6 months and 12 months of follow-up, respectively (McNemar p<0.0001). There was a significant reduction in tricuspid valve annular diameter (p<0.0001), coaptation distance (p<0.0001) and systolic tenting area (p<0.0001). The reduction in TR was also observed in patients who did not have concomitant tricuspid valve (TV) repair (from 15.3% to 6.9% and 11.8% at 6 and 12 months, respectively, p<0.0001). On multivariable logistic regression including all univariable predictors of residual TR at 12 months, only RA area remained in the model (OR 1.2, 95% CI 1.04 to 1.37, p=0.01). CONCLUSIONS: ASD closure and PVR are associated with a significant reduction in tricuspid regurgitation, even among patients who do not undergo concomitant tricuspid valve surgery.

RESUMO

Iodinated contrast media (CM) are the leading cause of acute renal failure of toxic origin. Between 21% and 50% of patients that receive them develop contrast-induced nephropathy (CIN). All prophylactic measures used so far have failed to provide effective prevention. Since oxidative stress is involved in the damage, a possible preventive strategy could be the administration of antioxidant substances, such as quercetin. This compound has shown renoprotective effects in experimental studies. The aim of this study was to evaluate whether quercetin may be helpful in preventing CIN in patients undergoing coronary catheterization. A clinical phase II study was conducted. Patients were distributed in two groups, namely, CM (patients who only received contrast media) and CM+Q (patients who were pretreated with quercetin orally for 3-5 days). Results showed less incidence of CIN in the CM+Q group, possibly due to glomerular protection, evidenced by a lower increase in serum creatinine and albuminuria; and a lower decrease in the glomerular filtration rate (GFR). Furthermore, in this group, the relative risk of developing CIN observed in patients that received a high dose of contrast media was inferior. In conclusion, this is the first study that demonstrates that quercetin is a promising safe candidate in preventing CIN.

RESUMO

INTRODUCTION: Among implantable cardioverter-defibrillator (ICD) patients, a substantial proportion of syncopes are due to fast ventricular tachycardias (FVTs). In the experimental models of ventricular tachycardias, the arterial vasoconstriction plays an important role in recovering the arterial pressure. Since beta-blockers increase vascular resistance, we hypothesized that beta-blockers could reduce the occurrence of syncope due to FVTs. Our objective was to determine the relationship between the beta-blocker therapy and the incidence of syncope in FVT (cycle length [CL] 250-320 ms) occurring in ICD patients. Slow VTs were excluded because of the lack of symptoms and VF episodes because of the small number. METHODS AND RESULTS: In this multicenter study, 226 patients (LVEF 31 ± 10%) with single-chamber ICDs were followed. FVT programming was standardized, including antitachycardia pacing (ATP) as initial therapy. Symptoms were correlated with ICD-stored episode data of FVTs. The beta-blocker therapy was determined at each FVT presentation. We analyzed 289 FVTs (CL 291 ± 21 ms; 77% under beta-blockers; median of the duration:8 s) occurring consecutively in 52 ICD patients. The frequency of FVT-related syncope was 22 (7.6%). Beta-blockers were associated with a lower heart rate preceding FVT (85 ± 22 vs. 94 ± 23 bpm; p = 0.009), a higher ATP effectiveness (86 vs. 57%; p < 0.001), a lower duration of episodes (8 [2] vs. 10 [14] s; p < 0.001), and a lower incidence of FVT-related syncope (4.5 vs. 18%; p < 0.001). By logistic regression, a FVT > 8 s (OR = 21; p = 0.003) and the beta-blocker therapy (OR = 0.3; p = 0.012) were found as independent predictors of syncope. CONCLUSION: Among ICD patients with left ventricular dysfunction, beta-blockers are associated with a lower incidence of FVT-related syncope.

RESUMO

Aims: Radiofrequency ablation (RFA) of septal accessory pathways (APs) is associated with a significant rate of first procedure failures and complications. Cryoablation is an alternative energy source but there are no studies comparing both ablation techniques. We aimed to systematically review the literature and compare the efficacy and safety of cryoablation vs. RFA of septal APs. Methods and results: We conducted two separate meta-analysis of cryoablation and RFA of septal APs and calculated the global estimates of the efficacy and safety. Sixty-four articles were included: 38 articles reporting RFA and 27 articles reporting cryoablation procedures. Additionally, we included the previously non-published cryoablation registry of septal APs performed at our institution. Overall, 4244 septal APs constitute our study population, 3495 in the RFA cohort and 749 in the cryoablation cohort. Acute procedural success rate of cryoablation was 86.0% (95% CI 81.6-89.4%) and RFA 89.0% (95% CI 86.8-91.0%). Recurrence rate of cryoablation was 18.1% (95% CI 14.8-21.8%) and RFA 9.9% (95% CI 8.2-12.0%). Long-term success rate after multiple ablation procedures of cryoablation was 75.9% (95% CI 68.2-82.3%) and RFA 88.4% (95% CI 84.7-91.3%). There were no reported cases of persistent atrioventricular block (AVB) with cryoablation and 2.7% (95% CI 2.2-3.4%) with RFA. Conclusion: Studies of RFA for treatment of septal APs report higher efficacy rates than do studies using cryoablation, but a significantly higher rate of AVB.

RESUMO

OBJECTIVES: Although a significant proportion of patients with cyanotic congenital heart disease are thrombocytopaenic, its prevalence and clinical significance in adults with Eisenmenger syndrome (ES) is not well studied. Accordingly, we examined the relationship of thrombocytopaenia and mean platelet volume (MPV) to bleeding or thrombotic complications and survival in a contemporary cohort of patients with ES, including patients with Down syndrome. METHODS: Demographics, laboratory and clinical data were analysed from 226 patients with ES under active follow-up over 11 years. RESULTS: Age at baseline was 34.6±11.4 years and 34.1% were men. Mean platelet count and MPV were 152.6±73.3×109/L and 9.6±1.2 fL, respectively. A strong inverse correlation was found between platelet count and haemoglobin concentration and MPV. During the study, there were 39 deaths, and 21 thrombotic and 43 bleeding events. On univariate Cox regression analysis, patients with a platelet count <100×109/L had a twofold increased mortality (HR 2.10, 95% CI 1.10 to 4.01, p=0.024). Platelet count was not associated with an increased risk of thrombosis. However, there was a threefold increased thrombotic risk with MPV >9.5 fL (HR 3.50, 95% CI 1.28 to 9.54, p=0.015). Patients with either severe secondary erythrocytosis (>220g/L) or anaemia (<130g/L) were at higher risk of thrombotic events (HR 3.93, 95% CI 1.60 to 9.67, p=0.003; and HR 4.75, 95% CI 1.03 to 21.84, p=0.045, respectively). CONCLUSIONS: Thrombocytopaenia significantly increased the risk of mortality in ES. Furthermore, raised MPV, severe secondary erythrocytosis and anaemia, but not platelet count, were associated with an increased risk of thrombotic events in our adult cohort.

RESUMO

La enfermedad cardiovascular suele estar en fase avanzada cuando aparecen los primeros síntomas. El hecho de que la presentación clínica inicial pueda ser letal o altamente incapacitante enfatiza la necesidad de la prevención primaria y secundaria. Se estima que la proporción de pacientes con buena adherencia en prevención secundaria de la enfermedad cardiovascular es baja y disminuye progresivamente en el tiempo. La Polypill para la prevención cardiovascular secundaria es el primer tratamiento combinado en dosis fija de ácido acetilsalicílico, atorvastatina y ramipril aprobada en España. El propósito de este documento de consenso fue definir y recomendar, a través de la evidencia en la literatura y la opinión clínica de expertos, el impacto de la adherencia al tratamiento de prevención cardiovascular secundaria y el uso en la práctica clínica de la Polypill integrado en una estrategia global que incluye modificaciones en el estilo de vida. Para la realización de este consenso se ha utilizado la metodología RAND/UCLA que está basada en la evidencia científica y en el juicio colectivo y experiencia clínica de un panel de expertos. Como resultado se ha elaborado un informe final de recomendaciones sobre el impacto de la falta de adherencia al tratamiento de la prevención cardiovascular secundaria y el efecto del uso de una Polypill en la adherencia terapéutica de los pacientes. Las recomendaciones de este documento se orientan a todos aquellos especialistas, cardiólogos, médicos internistas y médicos de atención primaria con competencia en la prescripción y seguimiento de los pacientes de alto y muy alto riesgo cardiovascular y que requieran prevención secundaria (AU)


Cardiovascular disease is a chronic disorder which is usually already at an advanced stage when the first symptoms develop. The fact that the initial clinical presentation can be lethal or highly incapacitating emphasizes the need for primary and secondary prevention. It is estimated that the ratio of patients with good adherence to secondary prevention of cardiovascular disease is low and also decreases gradually over time. The Polypill for secondary prevention of cardiovascular disease is the first fixed-dose combination therapy of salicylic acid, atorvastatin and ramipril approved in Spain. The purpose of this consensus document was to define and recommend, through the evidence available in the literature and clinical expert opinion, the impact of treatment adherence in the secondary prevention of cardiovascular disease and the use of the Polypill in daily clinical practice as part of a global strategy including adjustments in patient lifestyle. A RAND/UCLA methodology based on scientific evidence, as well as the collective judgment and clinical expertise of an expert panel was used for this assessment. As a result, a final report of recommendations on the impact of the lack of adherence to treatment of secondary prevention of cardiovascular disease and the effect of using a Polypill in adherence of patients was produced. The recommendations included in this document have been addressed to all those specialists, cardiologists, internists and primary care physicians with competence in prescribing and monitoring patients with high and very high cardiovascular risks (AU)
