Amiloidosis cardiaca: descripción de una serie de 143 casos / Cardiac amyloidosis: Description of a series of 143 cases

Introducción y objetivos: Recientemente se han producido importantes avances en el diagnóstico y tratamiento de la amiloidosis cardiaca (AC). Nos propusimos realizar una descripción actualizada de sus 2 tipos más frecuentes: la AC por transtirretina (AC-ATTR) y la AC por cadenas ligeras (AC-AL).MétodosRegistro prospectivo de pacientes diagnosticados de AC en 7 hospitales de Galicia entre el 1 de enero de 2018 y el 30 de junio de 2020. Se recogieron variables relativas a características clínicas, pruebas complementarias, supervivencia y causas de muerte.ResultadosSe incluyeron de forma consecutiva 143 pacientes con AC, 128 AC-ATTR (89,5%) y 15 AC-AL (10,5%). La edad media fue de 79,6±7,7 años y un 23,8% fueron mujeres. La mayoría de los pacientes con AC-ATTR se diagnosticaron de forma no invasiva (87,5%). En la exploración física, un 35,7, un 35 y un 7% de los pacientes presentaban el signo de Popeye, contractura de Dupuytren y macroglosia, respectivamente. La supervivencia a los 12 y 24 meses fue del 92,1 y el 76,2% en el grupo AC-ATTR, y del 78,6 y el 61,1% en el grupo AC-AL (p=0,152). La causa de muerte fue cardiovascular en el 80,8% de la cohorte.ConclusionesLa AC-ATTR puede ser diagnosticada en la mayoría de los casos de manera no invasiva y es la forma de AC más frecuente en la práctica clínica habitual. Además, parece observarse un aumento en la supervivencia a corto plazo de la AC que en parte podría deberse a los avances relacionados con su diagnóstico y tratamiento. (AU)

Introduction and objectives: Recently, there have been important advances in the diagnosis and treatment of cardiac amyloidosis (CA). Our aim was to provide an updated description of its 2 most frequent types: the transthyretin CA (ATTR-CA) and the light chain CA (AL-CA).MethodsProspective registry of patients with CA diagnosed in 7 institutions in Galicia (Spain) between January 1, 2018 and June 30, 2020. Variables related to clinical characteristics, complementary tests, survival and causes of death were collected.ResultsOne hundred and forty-three patients with CA were consecutively included, 128 ATTR-CA (89.5%) and 15 AL-CA (10.5%). Mean age was 79.6±7.7 years and 23.8% were women. Most patients with ATTR-CA were diagnosed non-invasively (87.5%). On physical examination, 35.7, 35 and 7% had Popeye's sign, Dupuytren's contracture and macroglossia, respectively. Twelve-month and 24-month survival was 92.1 and 76.2% in the ATTR-CA group, and 78.6 and 61.1% in the AL-CA group (P=.152). The cause of death was cardiovascular in 80.8% of the cohort.ConclusionsATTR-CA can be diagnosed non-invasively in most cases and it is the most common type of CA in routine clinical practice. Furthermore, an increase in the short-term survival of CA appears to be observed, which could be due to advances related to its diagnosis and treatment. (AU)

Syncope in patients with transthyretin amyloid cardiomyopathy: clinical features and outcomes.

BACKGROUND: We aimed to describe the clinical characteristics, underlying causes and outcomes of syncope in patients with transthyretin amyloid cardiomyopathy (ATTR-CM). METHODS: The clinical profile and underlying causes of syncopal episodes were reviewed in a cohort of 128 patients with ATTR-CM enrolled from January 2018 to June 2020 in a prospective multicentre registry in 7 hospitals of Galicia (Spain). After enrollment, patients were followed during a median period of 520 days. The effect of syncope on all-cause mortality was assessed by means of multivariate Cox´s regression. RESULTS: Thirty (23.4%) patients had a history of previous syncope as a clinical antecedent before being enrolled in the prospective phase of the registry, and 4 (3.1%) experienced a first episode of syncope thereafter. The estimated incidence density rate of syncope during the prospective follow-up period after registry enrollment was 71.9 episodes per 1000 patients-year (95% Confidence Interval (CI) 32.8-111.1). The estimated overall prevalence of syncope was 26.6% (95% CI 18.9%-34.2%). Cardiac arrhythmias (n = 11, 32.3%), structural diseases of the heart or great vessels (n = 5, 14.7%), a neurally mediated reflex (n = 6, 17.6%), and orthostatic hypotension (n = 4, 11.8%) were identified as probable underlying causes of syncope; in 8 (23.6%) patients, syncope remained unexplained. Patients with syncope had increased non-adjusted all-cause mortality than patients without it (univariate hazard-ratio 3.37; 95% CI 1.43-7.94). When other independent predictors of survival were added to the survival model, this association was no longer statistically significant (multivariate hazard-ratio 1.81, 95% CI 0.67-4.84). CONCLUSIONS: Syncope is frequent in patients with ATTR-CM. This study could not demonstrate an independent association between syncope and mortality in those individuals.Abbreviations: ATTR-CM: Transthyretin amyloid cardiomyopathy; CI: Confidence Interval; HF: Heart Failure; HR: Hazard Ratio; IQR: Interquartile rank; LVEF: Left Ventricular Ejection Fraction; NTproBNP: N-terminal pro-brain natriuretic peptide; SD: Standard Deviation; 99mTc-DPD: technetium-99m-labeled 3,3-diphosphono-1,2-propanodicarboxylic acid.

Beta-Blocker Exposure and Survival in Patients With Transthyretin Amyloid Cardiomyopathy.

OBJECTIVE: To investigate a potential association between beta-blocker exposure and survival in patients with transthyretin amyloid cardiomyopathy (ATTR-CM). METHODS: In this real-world prospective registry of 128 consecutive patients with ATTR-CM recruited in 7 institutions in Galicia (Spain), survival of 65 patients who received beta blockers on registry enrollment was compared with that of 63 untreated controls by means of both unweighted Cox regression and Cox regression with inverse probability of treatment weighting. Tolerance to and adverse effects of beta blockers were recorded. Median study follow-up was 520 days. RESULTS: Patients with ATTR-CM who received beta blockers showed statistically significant lower all-cause mortality than untreated controls as evaluated by either unweighted Cox regression (hazard ratio, 0.31; 95% CI, 0.12 to 0.79) or Cox regression with inverse probability of treatment weighting (hazard ratio, 0.18; 95% CI, 0.08 to 0.41; P<.001). Several sensitivity analyses confirmed the internal validity of these results. The overall frequency of beta-blocker suspension due to adverse effects was 25% (95% CI, 15.5% to 34.5%). CONCLUSION: In this real-world, prospective, multi-institutional registry, patients with ATTR-CM who received beta blockers had lower all-cause mortality than untreated controls.

Hyperkalaemia management and related costs in chronic kidney disease patients with comorbidities in Spain.

BACKGROUND: Hyperkalaemia (HK) is a common electrolyte disorder in patients with chronic kidney disease (CKD) and/or treated with renin-angiotensin-aldosterone system inhibitors (RAASis). The aim of this study is to determine the severity, current management and cost of chronic HK. METHODS: We performed a retrospective cohort study of patients with chronic HK and CKD, heart failure or diabetes mellitus between 2011 and 2018. The study follow-up was 36 months. RESULTS: A total of 1499 patients with chronic HK were analysed: 66.2% presented with mild HK, 23.4% with moderate HK and 10.4% with severe HK. The severity was associated with CKD stage. Most patients (70.4%) were on RAASi therapies, which were frequently discontinued (discontinuation rate was 39.8, 49.8 and 51.8% in mild, moderate and severe HK, respectively). This RAASi discontinuation was similar with or without resin prescription. Overall, ion-exchange resins were prescribed to 42.5% of patients with HK and prescriptions were related to the severity of HK, being 90% for severe HK. Adherence to resin treatment was very low (36.8% in the first year and 17.5% in the third year) and potassium remained elevated in most patients with severe HK. The annual healthcare cost per patient with HK was €5929, reaching €12 705 in severe HK. Costs related to HK represent 31.9% of the annual cost per HK patient and 58.8% of the specialized care cost. CONCLUSIONS: HK was usually managed by RAASi discontinuation and ion-exchange resin treatment. Most patients with HK were non-adherent to resins and those with severe HK remained with high potassium levels, despite bearing elevated healthcare expenditures.

Differences in the Clinical Profile and Management of Atrial Fibrillation According to Gender. Results of the REgistro GallEgo Intercéntrico de Fibrilación Auricular (REGUEIFA) Trial.

To analyze the clinical profile and therapeutic strategy in atrial fibrillation (AF) according to gender in a contemporaneous patient cohort a prospective, multicenter observational study was performed on consecutive patients diagnosed with AF and assessed by cardiology units in the region of Galicia (Spain). A total of 1007 patients were included, of which 32.3% were women. The mean age of the women was significantly greater than that of the men (71.6 versus 65.7 years; p < 0.001), with a higher prevalence of hypertension (HTN) and valve disease. Women more often reported symptoms related to arrhythmia (28.2% in EHRA class I versus 36.4% in men), with a poorer level of symptoms (EHRA classes IIb and III). Thromboembolic risk was significantly higher among women (CHA2DS2-VASc 3 ± 1.3 versus 2 ± 1.5), in the same way as bleeding risk (HAS-BLED 0.83 ± 0.78 versus 0.64 ± 0.78) (p < 0.001), and women more often received anticoagulation therapy (94.1% versus 87.6%; p = 0.001). Rhythm control strategies proved significantly less frequent in women (55.8% versus 66.6%; p = 0.001), with a lesser electrical cardioversion (ECV) rate (18.4% versus 27.3%; p = 0.002). Perceived health status was poorer in women. Women were older and presented greater comorbidity than men, with a greater thromboembolic and bleeding risk. Likewise, rhythm control strategies were less frequent than in men, despite the fact that women had poorer perceived quality of life and were more symptomatic.

Fibrilación auricular y cardiopatía isquémica: más allá de la prevención del ictus / Atrial fibrillation and ischemic heart disease: beyond stroke prevention

El objetivo principal en el abordaje del paciente con fibrilación auricular es la reducción del riesgo de ictus mediante el tratamiento antitrombótico adecuado. Sin embargo, a pesar de una adecuada anticoagulación, sigue habiendo un importante riesgo residual de eventos isquémicos, particularmente infarto de miocardio y muerte de origen cardiovascular, que exige una protección más completa. Por lo tanto, en el paciente con fibrilación auricular, el tratamiento anticoagulante debería perseguir este doble objetivo, la reducción tanto del riesgo de ictus como de las complicaciones isquémicas. Diferentes estudios han demostrado que los antagonistas de la vitamina K solo disminuyen el riesgo de ictus y de eventos isquémicos cuando el control de la anticoagulación es óptimo, cosa que ocurre en un pequeño número de pacientes. Con respecto a los anticoagulantes orales de acción directa, aunque en general muestran un perfil de eficacia y seguridad mejor que los antagonistas de la vitamina K, parece que no todos ofrecerían la misma protección en cuanto a la reducción de los eventos isquémicos. Está demostrado que el rivaroxabán reduce de manera significativa (18%) el riesgo de infarto de miocardio. De hecho, los estudios muestran que el rivaroxabán proporciona una protección vascular más completa en diferentes contextos clínicos, no solo en el paciente con fibrilación auricular, sino también en el paciente con enfermedad vascular ateroesclerótica

The main aim of management in patients with atrial fibrillation is to reduce the risk of stroke using appropriate antithrombotic treatment. However, despite adequate anticoagulation, there remains a substantial residual risk of ischemic events, particularly myocardial infarction and cardiovascular death. A more general approach is needed. Consequently, in patients with atrial fibrillation, anticoagulation treatment should seek to achieve the twin targets of reducing the risk of both stroke and ischemic events. Studies have demonstrated that vitamin K antagonists reduce the risk of stroke and ischemic events only when anticoagulation control is optimal, a situation that occurs in only a small number of patients. Direct oral anticoagulants are generally more effective and safer than vitamin K antagonists. However, not all direct oral anticoagulants appear to offer the same protection against ischemic events. It has been shown that rivaroxaban significantly reduces the risk of myocardial infarction (by 18%). In fact, studies demonstrate that rivaroxaban provides comprehensive vascular protection across a range of clinical scenarios, not only in patients with atrial fibrillation, but also in those with atherosclerotic vascular disease

Sudden infant death as the most severe phenotype caused by genetic modulation in a family with atrial fibrillation.

AIMS: To assess the functional impact of two combined KCNH2 variants involved in atrial fibrillation, syncope and sudden infant death syndrome. METHODS AND RESULTS: Genetic testing of a 4-month old SIDS victim identified a rare missense heterozygous in KCNH2 variant (V483I) and a missense homozygous polymorphism (K897T) which is often described as a genetic modifier. Electrophysiological characterisation of heterologous HERG channels representing two different KCNH2 genotypes within the family, showed significant differences in both voltage and time dependence of activation and inactivation with a global gain-of-function effect of mutant versus wild type channels and, also, differences between both types of recombinant channels. CONCLUSIONS: The rare variant V483I in combination with K897T produces a gain-of-function effect that represents a pathological substrate for atrial fibrillation, syncope and sudden infant death syndrome events in this family. Ascertaining the genotype-phenotype correlation of genetic variants is imperative for the correct assessment of genetic testing and counselling. TRANSLATIONAL PERSPECTIVE: According to the current guidelines for clinical interpretation of sequence variants, functional studies are an essential tool for the ascertainment of variant pathogenicity. They are especially relevant in the context of sudden infant death syndrome and sudden cardiac death, where individuals cannot be clinically evaluated. The patch-clamp technique is a gold-standard for analysis of the biophysical mechanisms of ion channels.

Evolución de los pacientes con estenosis aórtica grave tras la indicación de intervención / Prognosis of patients with severe aortic stenosis after the decision to perform an intervention

Introducción y objetivos: Los tratamientos actuales de la estenosis aórtica (EAo) grave incluyen el implante percutáneo de válvula aórtica (TAVI) y la cirugía de sustitución valvular aórtica (SVAo). El objetivo es describir la evolución de los pacientes con EAo grave tras la indicación de intervención, las variables que influyen en su pronóstico y los determinantes de un tiempo de espera superior a 2 meses. Métodos: Subanálisis del registro IDEAS (Influencia del Diagnóstico de Estenosis Aórtica Severa) en los pacientes a los que se indicó intervención. Resultados: De 726 pacientes con EAo grave diagnosticada en enero de 2014, se indicó intervención a 300 que son el foco del presente estudio. La media de edad era 74,0 +/- 9,7 años. Se intervino a 258 pacientes (86,0%): 59 con TAVI y 199 con SVAo. Al año, 42 (14,0%) continuaban sin intervención, ya sea por seguir en espera (34) o haber fallecido (8). La mitad de los pacientes que murieron antes del procedimiento fallecieron en los primeros 100 días. El tiempo hasta la intervención fue 2,9 +/- 1,6 meses para el TAVI y 3,5 +/- 0,2 meses para la SVAo (p = 0,03). Los predictores de mortalidad independientes fueron el sexo masculino (HR = 2,6; IC95%, 1,1-6,0), la insuficiencia mitral moderada-grave (HR = 2,6; IC95%, 1,5-4,5), la movilidad reducida (HR = 4,6; IC95%, 1,7-12,6) y la falta de intervención (HR = 2,3; IC95%, 1,02-5,03). Conclusiones: Los pacientes con EAo grave en espera de intervención tienen alto riesgo de mortalidad. Hay indicadores clínicos asociados con peor pronóstico que podrían indicar la necesidad de una intervención precoz

Introduction and objectives: Current therapeutic options for severe aortic stenosis (AS) include transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR). Our aim was to describe the prognosis of patients with severe AS after the decision to perform an intervention, to study the variables influencing their prognosis, and to describe the determinants of waiting time > 2 months. Methods: Subanalysis of the IDEAS (Influence of the Severe Aortic Stenosis Diagnosis) registry in patients indicated for TAVI or SAVR. Results: Of 726 patients with severe AS diagnosed in January 2014, the decision to perform an intervention was made in 300, who were included in the present study. The mean age was 74.0 +/- 9.7 years. A total of 258 (86.0%) underwent an intervention: 59 TAVI and 199 SAVR. At the end of the year, 42 patients (14.0%) with an indication for an intervention did not receive it, either because they remained on the waiting list (34 patients) or died while waiting for the procedure (8 patients). Of the patients who died while on the waiting list, half did so in the first 100 days. The mean waiting time was 2.9 +/- 1.6 for TAVI and 3.5 +/- 0.2 months for SAVR (P = .03). The independent predictors of mortality were male sex (HR, 2.6; 95%CI, 1.1-6.0), moderate-severe mitral regurgitation (HR, 2.6; 95%CI, 1.5-4.5), reduced mobility (HR, 4.6; 95%CI, 1.7-12.6), and non intervention (HR, 2.3; 95%CI, 1.02-5.03). Conclusions: Patients with severe aortic stenosis a waiting therapeutic procedures have a high mortality risk. Some clinical indicators predict a worse prognosis and suggest the need for early intervention

CONCLUSIONS: Patients with severe aortic stenosis awaiting therapeutic procedures have a high mortality risk. Some clinical indicators predict a worse prognosis and suggest the need for early intervention.

Heart failure with recovered ejection fraction: Clinical characteristics, determinants and prognosis. CARDIOCHUS-CHOP registry.

BACKGROUND: The magnitude and the prognostic impact of recovering left ventricular ejection fraction (LVEF) in patients with heart failure (HF) and systolic dysfunction is unclear. The aim of this study was to evaluate the clinical characteristics and prognosis of patients with HFrecEF in an HF population. METHODS: 449 consecutive patients were selected with the diagnosis of HF and an evaluation of LVEF in the 6 months prior to selection who were referred to two HF units. Patients with systolic dysfunction were only considered if a second echocardiogram was performed during the follow-up. RESULTS: At the time of diagnosis, 207 patients had LVEF > 40% (HFpEF) and 242 had LVEF ≤ 40% (HFrEF). After 1 year, the LVEF was re-evaluated in all 242 patients with a LVEF ≤ 40%: in 126 (52%), the second LVEF was > 40% (HFrecEF), and the remaining 116 (48%) had LVEF ≤ 40% (HFrEF). After 1800 ± 900 days of follow-up patients with recovered LVEF had a significantly lower mortality rate (HFpEF vs. HFrecEF: hazard ratio [HR] = 2.286, 95% confidence interval [95% CI] 1.264-4.145, p = 0.019; HFrEF vs. HFrecEF: HR = 2.222, 95% CI 1.189-4.186, p < 0.001) and hospitalization rate (HFpEF vs. HFrecEF: HR = 1.411, 95% CI 1.046-1.903, p = 0.024; HFrEF vs. HFrecEF: HR = 1.388, 95% CI 1.002-1.924, p = 0.049). The following are predictors of LVEF recovery: younger age, lower functional class, treatment with renin-angiotensin-aldosterone system inhibitors and beta-blockers, absence of defibrillator use, and non-ischemic etiology. CONCLUSIONS: Patients with HF and reduced LVEF who were re-evaluated after 1 year, had significant improvement in their LVEF and had a more favourable prognosis than HF with preserved and reduced ejection fraction.

Comparison of 1-Year Outcome in Patients With Severe Aorta Stenosis Treated Conservatively or by Aortic Valve Replacement or by Percutaneous Transcatheter Aortic Valve Implantation (Data from a Multicenter Spanish Registry).

The factors that influence decision making in severe aortic stenosis (AS) are unknown. Our aim was to assess, in patients with severe AS, the determinants of management and prognosis in a multicenter registry that enrolled all consecutive adults with severe AS during a 1-month period. One-year follow-up was obtained in all patients and included vital status and aortic valve intervention (aortic valve replacement [AVR] and transcatheter aortic valve implantation [TAVI]). A total of 726 patients were included, mean age was 77.3 ± 10.6 years, and 377 were women (51.8%). The most common management was conservative therapy in 468 (64.5%) followed by AVR in 199 (27.4%) and TAVI in 59 (8.1%). The strongest association with aortic valve intervention was patient management in a tertiary hospital with cardiac surgery (odds ratio 2.7, 95% confidence interval 1.8 to 4.1, p <0.001). The 2 main reasons to choose conservative management were the absence of significant symptoms (136% to 29.1%) and the presence of co-morbidity (128% to 27.4%). During 1-year follow-up, 132 patients died (18.2%). The main causes of death were heart failure (60% to 45.5%) and noncardiac diseases (46% to 34.9%). One-year survival for patients treated conservatively, with TAVI, and with AVR was 76.3%, 94.9%, and 92.5%, respectively, p <0.001. One-year survival of patients treated conservatively in the absence of significant symptoms was 97.1%. In conclusion, most patients with severe AS are treated conservatively. The outcome in asymptomatic patients managed conservatively was acceptable. Management in tertiary hospitals is associated with valve intervention. One-year survival was similar with both interventional strategies.

Systemic sclerosis: a rare cause of heart failure?

Systemic sclerosis (SS) is a chronic disease in which there may be multisystem involvement. It is rare (estimated prevalence: 0.5-2/10000) with high morbidity and mortality, and there is as yet no curative treatment. We report the case of a young woman newly diagnosed with SS, in whom decompensated heart failure was the main manifestation.

Centenarians and their hearts: A prospective registry with comprehensive geriatric assessment, electrocardiogram, echocardiography, and follow-up.

BACKGROUND: Data on the cardiac characteristics of centenarians are scarce. Our aim was to describe electrocardiogram (ECG) and echocardiography in a cohort of centenarians and to correlate them with clinical data. METHODS: We used prospective multicenter registry of 118 centenarians (28 men) with a mean age of 101.5±1.7 years. Electrocardiogram was performed in 103 subjects (87.3%) and echocardiography in 100 (84.7%). All subjects underwent a follow-up for at least 6 months. RESULTS: Centenarians with abnormal ECG were less frequently females (72% vs 93%), had higher rates of previous consumption of tobacco (14% vs 0) and alcohol (24% vs 12%), and scored lower in the perception of health status (6.8±2.0 vs 8.3±6.8). Centenarians with significant abnormalities in echocardiography were less frequently able to walk 6 m (33% vs 54%). Atrial fibrillation/flutter was found in 27 subjects (26%). Mean left ventricular (LV) ejection fraction was 60.0±10.5%. Moderate or severe aortic valve stenosis was found in 16%, mitral valve regurgitation in 15%, and aortic valve regurgitation in 13%. Diastolic dysfunction was assessed in 79 subjects and was present in 55 (69.6%). Katz index and LV dilation were independently associated with the ability to walk 6 m. Age, Charlson and Katz indexes, and the presence of significant abnormalities in echocardiography were associated with mortality. CONCLUSIONS: Centenarians have frequent ECG alterations and abnormalities in echocardiography. More than one fifth has atrial fibrillation, and most have diastolic dysfunction. Left ventricular dilation was associated with the ability to walk 6 m. Significant abnormalities in echocardiography were associated with mortality.
