RESUMO

INTRODUCTION AND OBJECTIVES: Atrioventricular block (AVB) in the presence of bradycardic drugs (BD) can be reversible, and pacemaker implantation is controversial. Our objective was to analyze the pacemaker implantation rate in the mid-term, after BD suspension, and to identify predictive factors. METHODS: We performed a cohort study that included patients attending the emergency department with high-grade AVB in the context of BD. We studied the persistence of AVB after BD discontinuation, recurrence in patients with AVB resolution, and the predictive variables associated with pacemaker requirement at 3 years. RESULTS: Of 127 patients included (age, 79 [71-83] years), BAV resolved in 60 (47.2%); among these patients, recurrence occurred during the 24-month median follow-up in 40 (66.6%). Pacemaker implantation was required in 107 patients (84.3%), despite BD discontinuation. On multivariable analysis, the variables associated with pacemaker need at 3 years were heart rate <35 bpm (OR, 8.12; 95%CI, 1.82-36.17), symptoms other than syncope (OR, 4.09; 95%CI, 1.18-14.13), and wide QRS (OR, 5.65; 95%CI, 1.77-18.04). Concomitant antiarrhythmic treatment was associated with AVB resolution (OR, 0.12; 95%CI, 0.02-0.66). CONCLUSIONS: More than 80% of patients with AVB secondary to BD require pacemaker implantation despite drug discontinuation. Predictive variables were wide QRS, heart rate <35 bpm, and clinical presentation other than syncope.

RESUMO

INTRODUCTION AND OBJECTIVES: This study sought to analyze the association of early coronary angiography with all-cause mortality and cardiovascular mortality in patients with non-ST-segment elevation acute coronary syndrome (NSTEACS) using a large contemporary cohort of patients with NSTEACS from 2 Spanish tertiary hospitals. METHODS: This retrospective observational study included 5673 consecutive NSTEACS patients from 2 Spanish hospitals between 2005 and 2016. We performed propensity score matching to obtain a well-balanced subset of patients with the same probability of undergoing an early strategy, resulting in 3780 patients. Survival analyses were performed by Cox regression models once proportional risk test were verified. RESULTS: Among the study participants, only 2087 patients (40.9%) underwent early invasive coronary angiography. The median follow-up was 59.0 months [interquartile range, 25.0-80.0 months]. All-cause mortality was 19.0%, cardiovascular mortality was 12.8%, and 51.1% patients experienced at least 1 major cardiovascular adverse event in the follow-up. After propensity score matching, the early strategy was associated with significantly lower mortality (hazard ratio: 0.79; 95% confidence interval 0.62-0.98) in high-risk NSTEACS patients. The darly strategy showed a nonsignificant inverse tendency in patients with GRACE score <140. CONCLUSIONS: In high-risk (GRACE score≥ 140) NSTEACS patients in a contemporary real-world registry, early coronary angiography (first 24hours after hospital admission) may be associated with reduced all-cause mortality and cardiovascular mortality at long-term follow-up.

RESUMO

BACKGROUND AND OBJECTIVES: The risk of major adverse cardiac and cerebrovascular events following acute coronary syndrome is increased in people with diabetes. Predicting out-of-hospital outcomes upon follow-up remains difficult, and no simple, well-validated tools exist for this population at present. We aim to evaluate several factors in a competing risks model for actionable evaluation of the incidence of major adverse cardiac and cerebrovascular events in diabetic outpatients following acute coronary syndrome. METHODS: Retrospective analysis of consecutive patients admitted for acute coronary syndrome in two centres. A Fine-Gray competing risks model was adjusted to predict major adverse cardiac and cerebrovascular events and all-cause mortality. A point-based score is presented that is based on this model. RESULTS: Out of the 1400 patients, there were 783 (55.9%) with at least one major adverse cardiac and cerebrovascular event (417 deaths). Of them, 143 deaths were due to non-major adverse cardiac and cerebrovascular events. Predictive Fine-Gray models show that the 'PG-HACKER' risk factors (gender, age, peripheral arterial disease, left ventricle function, previous congestive heart failure, Killip class and optimal medical therapy) were associated to major adverse cardiac and cerebrovascular events. CONCLUSION: The PG-HACKER score is a simple and effective tool that is freely available and easily accessible to physicians and patients. The PG-HACKER score can predict major adverse cardiac and cerebrovascular events following acute coronary syndrome in patients with diabetes.

RESUMO

BACKGROUND: The optimal diuretic treatment strategy for patients with acute heart failure and renal dysfunction remains unclear. Plasma carbohydrate antigen 125 (CA125) is a surrogate of fluid overload and a potentially valuable tool for guiding decongestion therapy. The aim of this study was to determine if a CA125-guided diuretic strategy is superior to usual care in terms of short-term renal function in patients with acute heart failure and renal dysfunction at presentation. METHODS: This multicenter, open-label study randomized 160 patients with acute heart failure and renal dysfunction into 2 groups (1:1). Loop diuretics doses were established according to CA125 levels in the CA125-guided group (n = 79) and in clinical evaluation in the usual-care group (n = 81). Changes in estimated glomerular filtration rate (eGFR) at 72 and 24 hours were the co-primary endpoints, respectively. RESULTS: The mean age was 78 ± 8 years, the median amino-terminal pro-brain natriuretic peptide was 7765 pg/mL, and the mean eGFR was 33.7 ± 11.3 mL/min/1.73m2. Over 72 hours, the CA125-guided group received higher furosemide equivalent dose compared to usual care (P = 0.011), which translated into higher urine volume (P = 0.042). Moreover, patients in the active arm with CA125 >35 U/mL received the highest furosemide equivalent dose (P <0.001) and had higher diuresis (P = 0.013). At 72 hours, eGFR (mL/min/1.73m2) significantly improved in the CA125-guided group (37.5 vs 34.8, P = 0.036), with no significant changes at 24 hours (35.8 vs 39.5, P = 0.391). CONCLUSION: A CA125-guided diuretic strategy significantly improved eGFR and other renal function parameters at 72 hours in patients with acute heart failure and renal dysfunction.

RESUMO

En los últimos años ha emergido un interés creciente sobre la relación entre el cáncer y las enfermedades cardiovasculares. El aumento de la esperanza de vida de ambas enfermedades ha condicionado su coexistencia cada vez más frecuente en un mismo paciente, con lo cual se ponen de relieve reacciones adversas farmacológicas que suponen un mayor riesgo para los pacientes. Esto es especialmente relevante en el caso de la ateroesclerosis, que parece compartir un sustrato fisiopatológico común con el cáncer. En esta revisión se analizan estos factores de riesgo comunes y de forma específica la relación entre los diferentes tratamientos del cáncer y el riesgo de enfermedad coronaria o cerebrovascular, así como la evidencia científica actual sobre la posible relación entre la terapia antiagregante y el riesgo de cáncer. Se repasan también de manera bidireccional la incidencia y el pronóstico del cáncer en pacientes con ateroesclerosis y viceversa, documentado en la información de los últimos estudios publicados en el campo de la cardiooncología


In the last few years, there has been growing interest in the relationship between cancer and cardiovascular disease. The increase in life expectancy in both diseases has led to their frequent coexistence in the same patient, which can lead to adverse drug reactions that increase patient risk. This is especially relevant in the case of atherosclerosis, which seems to share a common pathophysiological substrate with cancer. In this review, we analyze these common risk factors, and specifically analyze the relationship between different cancer treatments with the risk of coronary or cerebrovascular disease, as well as the current scientific evidence on the possible relationship between antiplatelet therapy and cancer risk. We also review the incidence and prognosis of cancer in patients with atherosclerosis and vice versa, based on the information reported in the most recently published studies in the field of cardio-oncology

RESUMO

Background: Patients with COPD are at higher risk of presenting with atrial fibrillation (AF). Information about clinical outcomes and optimal medical treatment of AF in the setting of COPD remains missing. We aimed to describe the prevalence of COPD in a sizeable cohort of real-world AF patients belonging to the same healthcare area and to examine the relationship between comorbid COPD and AF prognosis. Methods: Prospective analysis performed in a specific healthcare area. Data were obtained from several sources within the "data warehouse of the Galician Healthcare Service" using multiple analytical tools. Statistical analyses were completed using SPSS 19 and STATA 14.0. Results: A total of 7,990 (2.08%) patients with AF were registered throughout 2013 in our healthcare area (n=348,985). Mean age was 76.83±10.51 years and 937 (11.7%) presented with COPD. COPD patients had a higher mean CHA2DS2-VASc (4.21 vs 3.46; P=0.02) and received less beta-blocker and more digoxin therapy than those without COPD. During a mean follow-up of 707±103 days, 1,361 patients (17%) died. All-cause mortality was close to two fold higher in the COPD group (28.3% vs 15.5%; P<0.001). Independent predictive factors for all-cause mortality were age, heart failure, diabetes, previous thromboembolic event, dementia, COPD, and oral anticoagulation (OA). There were nonsignificant differences in thromboembolic events (1.7% vs 1.5%; P=0.7), but the rate of hemorrhagic events was significantly higher in the COPD group (3.3% vs 1.9%; P=0.004). Age, valvular AF, OA, and COPD were independent predictive factors for hemorrhagic events. In COPD patients, age, heart failure, vasculopathy, lack of OA, and lack of beta-blocker use were independent predictive factors for all-cause mortality. Conclusion: AF patients with COPD have a higher incidence of adverse events with significantly increased rates of all-cause mortality and hemorrhagic events than AF patients without COPD. However, comorbid COPD was not associated with differences in cardiovascular death or stroke rate. OA and beta-blocker treatment presented a risk reduction in mortality while digoxin use exerted a neutral effect.

RESUMO

BACKGROUND: The magnitude of the association between diabetes (DM) and outcomes in elderly patients with acute coronary syndromes (ACS) is controversial. No study assessed the prognostic impact of DM according to frailty status in these patients. METHODS: The LONGEVO-SCA registry included unselected ACS patients aged ≥ 80 years. Frailty was assessed by the FRAIL scale. We evaluated the impact of previous known DM on the incidence of death or readmission at 6 months according to status frailty by the Cox regression method. RESULTS: A total of 532 patients were included. Mean age was 84.3 years, and 212 patients (39.8%) had previous DM diagnosis. Patients with DM had more comorbidities and higher prevalence of frailty (33% vs 21.9%, p = 0.002). The incidence of death or readmission at 6 months was higher in patients with DM (HR 1.52, 95% CI 1.12-2.05, p 0.007), but after adjusting for potential confounders this association was not significant. The association between DM and outcomes was not significant in robust patients, but it was especially significant in patients with frailty [HR 1.72 (1.05-2.81), p = 0.030, p value for interaction = 0.049]. CONCLUSIONS: About 40% of elderly patients with ACS had previous known DM diagnosis. The association between DM and outcomes was different according to frailty status.

RESUMO

BACKGROUND: Recent studies suggest that the benefit of mineralocorticoid receptor antagonists in the acute coronary syndrome setting is controversial. The aim of this study was to examine the current long-term prognostic benefit of mineralocorticoid receptor antagonists in patients with acute coronary syndrome. MATERIAL AND METHODS: We conducted a retrospective cohort study of 8318 consecutive acute coronary syndrome patients. Baseline patient characteristics were examined and a follow-up period was established for registry of death, major cardiovascular adverse events and heart failure re-hospitalization. We performed a propensity-matching analysis to draw up two groups of patients paired according to whether or not they had been treated with mineralocorticoid receptor antagonists. The prognostic value of mineralocorticoid receptor antagonists to predict events during follow-up was analysed using Cox regression. RESULTS: Among the study participants, only 524 patients (6.3%) were discharged on mineralocorticoid receptor antagonists. Patients on mineralocorticoid receptor antagonists had a different clinical and pharmacological profile. These differences disappeared after the propensity score analysis. The median follow-up was 40.7 months. After the propensity score analysis, the cardiovascular mortality and heart failure readmission rates were similar between patients who were discharged on mineralocorticoid receptor antagonists and those whose not. The use of mineralocorticoid receptor antagonists was only associated with a reduction in major cardiovascular adverse events (hazard ratio=0.83, 95% confidence interval 0.69-0.97, p=0.001). CONCLUSIONS: Our results do not corroborate the long-term benefit of mineralocorticoid receptor antagonists to improve survival after acute coronary syndrome in a large cohort of patients with heart failure or reduced left ventricular ejection fraction and diabetes. Their prescription was associated with a significantly lower incidence of major cardiovascular adverse events during the long-term follow-up without effect on heart failure development.

RESUMO

BACKGROUND: Stroke is one the most feared cardiovascular disease due to its high risk of disability and its incidence after an acute coronary syndrome (ACS) is not uncommon. METHODS: Retrospective study of all consecutive patients admitted for an ACS in two hospitals. Competing risk regression, taking all-cause mortality as a competing event, was used for the assessment of stroke incidence. RESULTS: We included 8771 patients, AF prevalence 12.4%. AF patients were older and presented higher prevalence of cardiovascular risk factors, previous cardiovascular disease, and lower glomerular filtration rate. Less than half of AF patients were receiving oral anticoagulation before admission. In-hospital mortality was 5.1% and it was more than two-fold higher in AF patients (10.2% vs. 4.4%; p < 0.01). Relevant differences on medical treatments were observed at discharge and oral anticoagulation was roughly <50% in AF patients. During a median follow-up was 58.7 months, 313 patients experienced at least one stroke (incidence 3.8%, 95% CI 3.4-4.2,) and it was 2-fold higher in patients with AF: 7.8% vs. 3.3% (p < 0.01). Median time to first stroke was 33.0 (30.1) months and it was shorter for AF patients compared to non-AF patients (28.2 ±â€¯22.3 vs. 34.6 ±â€¯31.1; p < 0.01). The adjusted competing risk regression identified AF, previous stroke and CHA2DS2-VASc score = 2 or ≥3 as independent predictors of stroke; CHA2DS2-VASc score = 2 was associated to higher risk of stroke only in AF patients. CONCLUSIONS: The long-term incidence of stroke after an ACS was 3.8%, 7.8% in AF-patients and 3.3% in patients without any diagnosis of AF.

RESUMO

Introducción y objetivos: La miocardiopatía arritmogénica del ventrículo derecho (MCAVD) es una cardiopatía hereditaria definida por la sustitución progresiva de miocardio ventricular derecho por tejido fibroadiposo. Es causa frecuente de la muerte súbita de jóvenes atletas. El objetivo del presente estudio es conocer la incidencia de variantes desmosómicas patogénicas o probablemente patogénicas en pacientes con MCAVD definitiva de alto riesgo. Métodos: El estudio de cohortes retrospectivo observacional incluyó a 36 pacientes diagnosticados de MCAVD definitiva de alto riesgo en nuestro hospital entre enero de 1998 y enero de 2015. El análisis genético se realizó con next-generation sequencing. Resultados: La mayoría eran varones (28 pacientes, 78%) con una media de edad al diagnóstico de 45 ± 18 años. Se detectó al menos 1 variante desmosómica patogénica o probablemente patogénica en 26 de los 35 casos índice (74%): 5 nonsense, 14 frameshift, 1 splice y 6 missense. En 15 pacientes (71%) se encontraron mutaciones nuevas. La presencia o la ausencia de mutaciones desmosómicas o la naturaleza de estas no se asociaron con características electrocardiográficas, clínicas, arrítmicas, anatómicas o pronósticas específicas. Conclusiones: La incidencia de variantes desmosómicas patogénicas o probablemente patogénicas en MCAVD definitiva de alto riesgo fue muy alta, con mayoría de mutaciones que causan truncamiento. La presencia de mutaciones desmosómicas no se asoció con el pronóstico


Introduction and objectives: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is an inherited cardiomyopathy characterized by progressive fibrofatty replacement of predominantly right ventricular myocardium. This cardiomyopathy is a frequent cause of sudden cardiac death in young people and athletes. The aim of our study was to determine the incidence of pathological or likely pathological desmosomal mutations in patients with high-risk definite ARVC. Methods: This was an observational, retrospective cohort study, which included 36 patients diagnosed with high-risk ARVC in our hospital between January 1998 and January 2015. Genetic analysis was performed using next-generation sequencing. Results: Most patients were male (28 patients, 78%) with a mean age at diagnosis of 45 ± 18 years. A pathogenic or probably pathogenic desmosomal mutation was detected in 26 of the 35 index cases (74%): 5 nonsense, 14 frameshift, 1 splice, and 6 missense. Novel mutations were found in 15 patients (71%). The presence or absence of desmosomal mutations causing the disease and the type of mutation were not associated with specific electrocardiographic, clinical, arrhythmic, anatomic, or prognostic characteristics. Conclusions: The incidence of pathological or likely pathological desmosomal mutations in ARVC is very high, with most mutations causing truncation. The presence of desmosomal mutations was not associated with prognosis

RESUMO

Introducción y objetivos: Actualmente existen pocos datos sobre la incidencia y el pronóstico de la insuficiencia cardiaca (IC) y la fracción de eyección del ventrículo izquierdo (FEVI) en el escenario del síndrome coronario agudo (SCA). El objetivo del estudio fue determinar la relación de la FEVI y la IC con el pronóstico a largo plazo en una cohorte de pacientes con SCA. Métodos: Se trata de un estudio retrospectivo observacional de 6.208 pacientes consecutivos ingresados por SCA en 2 hospitales españoles. Se determinaron las características clínicas y se consideró como objetivo primario la mortalidad y/o el reingreso por IC durante el seguimiento. Resultados: Entre los 5.064 participantes, presentaron SCA sin IC durante el ingreso: 290 (5,8%) con FEVI < 40%, 540 (10,6%) con FEVI 40-49% y 4.234 (83,6%) con FEVI ≥ 50%. De los 1.144 pacientes restantes 395 (34,6%) con FEVI < 40%, 251 (21,9%) FEVI 40-49% y 498 (43,5%) FEVI ≥ 50%. Los pacientes con FEVI del 40-49% tenían un perfil clínico y demográfico con características intermedias entre los pacientes presentaban FEVI < 40% y FEVI ≥ 50%. Las curvas de Kaplan-Meier mostraron que la mortalidad y el reingreso por IC eran significativamente distintos en función de la FEVI únicamente en los pacientes sin IC. En este grupo, la FEVI ≥ 50% fue un factor pronóstico independiente. Conclusiones: En el SCA, el pronóstico a largo plazo es considerablemente peor en los pacientes que desarrollan IC durante el ingreso, independientemente del valor de la FEVI. Este parámetro solo es en un factor pronóstico en los pacientes sin IC


Introduction and objectives: Contemporary data on the incidence and prognosis of heart failure (HF) and the influence of left ventricular ejection fraction (LVEF) in the setting of acute coronary syndrome (ACS) are scant. The aim of this study was to examine the relationship between LVEF and HF with long-term prognosis in a cohort of patients with ACS. Methods: This is a retrospective observational study of 6208 patients consecutively admitted for ACS to 2 different Spanish hospitals. Baseline characteristics were examined and a follow-up period was established for registration of death and HF rehospitalization as the primary endpoint. Results: Among the study participants, 5064 had ACS without HF during hospitalization: 290 (5.8%) had LVEF < 40%, 540 (10.6%) LVEF 40% to 49%, and 4234 (83.6%) LVEF ≥ 50%. The remaining 1144 patients developed HF in the acute phase: 395 (34.6%) had LVEF < 40%, 251 (21.9%) LVEF 40% to 49%, and 498 (43.5%) LVEF ≥ 50%. Patients with LVEF 40% to 49% had a demographic and clinical profile with intermediate features between the LVEF < 40% and LVEF ≥ 50% groups. Kaplan-Meier curves showed that mortality and HF readmissions were statistically different depending on LVEF in the non-HF group but not in the HF group. Left ventricular ejection fraction ≥ 50% was an independent prognostic factor in the non-HF group only. Conclusions: In ACS, long-term prognosis is considerably worse in patients who develop HF during hospitalization than in patients without HF, irrespective of LVEF. This parameter is a strong prognostic predictor only in patients without HF
