ABSTRACT

BACKGROUND: Pulmonary hypertension is a condition that involves the remodeling of the right ventricle. Ongoing remodeling is also associated with disease prognosis. During the restructuring process, complex changes such as hypertrophy and dilatation may also be reflected in electrocardiographic parameters. OBJECTIVES: Our study aimed to investigate the relationship between prognosis and electrocardiographic parameters in patients with pulmonary arterial hypertension. METHODS: The study was designed retrospectively and included patients diagnosed with pulmonary arterial hypertension between 2010 and 2022. The patients were divided into two groups based on their survival outcome. Various parameters, including electrocardiographic, demographic, echocardiographic, catheter, and blood parameters, were compared between the two groups. A p-value of <0.05 was considered statistically significant. RESULTS: In the multivariate Cox analyses, the parameters that were found to be independently associated with survival were the 6-minute walk test, mean pulmonary artery pressure, presence of pericardial effusion, and time between the beginning of the QRS and the peak of the S wave (RS time) (p<0.05 for each). Of all the parameters, RS time demonstrated the best diagnostic performance (AUC:0.832). In the survival analysis, a significant correlation was found between RS time and survival when using a cut-off value of 59.5 ms (HR: 0.06 [0.02-0.17], p < 0.001). CONCLUSIONS: According to the results of our study, a longer RS time is associated with poor prognosis in patients with pulmonary arterial hypertension. We can obtain information about the course of the disease with a simple, non-invasive parameter.


FUNDAMENTO: A hipertensão pulmonar é uma condição que envolve a remodelação do ventrículo direito. A remodelação contínua também está associada ao prognóstico da doença. Durante o processo de reestruturação, alterações complexas como hipertrofia e dilatação também podem se refletir nos parâmetros eletrocardiográficos. OBJETIVOS: Nosso estudo teve como objetivo investigar a relação entre prognóstico e parâmetros eletrocardiográficos em pacientes com hipertensão arterial pulmonar. MÉTODOS: O estudo foi desenhado retrospectivamente e incluiu pacientes com diagnóstico de hipertensão arterial pulmonar entre 2010 e 2022. Os pacientes foram divididos em dois grupos com base no resultado de sobrevida. Vários parâmetros, incluindo parâmetros eletrocardiográficos, demográficos, ecocardiográficos, de cateter e sanguíneos, foram comparados entre os dois grupos. Um valor de p <0,05 foi considerado estatisticamente significativo. RESULTADOS: Na análise multivariada de Cox, os parâmetros que se mostraram independentemente associados à sobrevida foram o teste de caminhada de 6 minutos, pressão média da artéria pulmonar, presença de derrame pericárdico e tempo entre o início do QRS e o pico da onda S (tempo de RS) (p<0,05 para cada). De todos os parâmetros, o tempo de RS demonstrou o melhor desempenho diagnóstico (AUC: 0,832). Na análise de sobrevida, foi encontrada correlação significativa entre o tempo de RS e a sobrevida ao utilizar o valor de corte de 59,5 ms (HR: 0,06 [0,02-0,17], p < 0,001). CONCLUSÕES: De acordo com os resultados do nosso estudo, um tempo de RS mais longo está associado a um pior prognóstico em pacientes com hipertensão arterial pulmonar. Podemos obter informações sobre o curso da doença com um parâmetro simples e não invasivo.

ABSTRACT

RESUMEN Introducción: la adherencia terapéutica es un problema multifactorial que ha generado el interés de muchos investigadores a nivel mundial. Objetivo: determinar la adherencia al tratamiento antihipertensivo en pacientes adultos mayores y los factores asociados a la no adherencia. Materiales y métodos: se realizó un estudio descriptivo longitudinal en pacientes adultos mayores hipertensos, pertenecientes al Policlínico Comunitario Sur, del municipio Morón, en la provincia de Ciego de Ávila. La adherencia al tratamiento fue evaluada por el cuestionario Martín-Bayarre-Grau y el nivel de conocimiento de la enfermedad por el Test de Batalla. Se identificaron las causas asociadas a los problemas de adherencia en dichos pacientes. Resultados: Predominó la no adherencia al tratamiento antihipertensivo en un 62 %. La adherencia parcial se constató en un 22 %. Los problemas de adherencia prevalecieron en las féminas de 60-69 años de edad. Se detectaron múltiples causas inherentes al paciente, como el olvido (48,4 %), la no disponibilidad de medicamentos (25,8 %) y el alivio de los síntomas (16,1 %). Entre otras causas se detectó el bajo nivel de conocimiento de la enfermedad y la presencia de comorbilidades. Conclusiones: se evidenció un predominio de adherencia al tratamiento antihipertensivo de los adultos mayores. Sus causas fundamentales fueron el olvido de ingerir el medicamento, la no disponibilidad de medicamentos, la falta de conocimientos sobre la enfermedad y la presencia de comorbilidades (AU).


ABSTRACT Introduction: therapeutic adherence is a multifactorial problem that has generated the interest of many researchers worldwide. Objective: to determine adherence to antihypertensive therapy in older adult patients and the factors associated with no adherence. Materials and methods: a longitudinal descriptive study was carried out in hypertensive elderly patients belonging to the South Community Polyclinic, in the municipality of Moron, in the province of Ciego de Avila. The adherence to treatment was evaluated by the Martín-Bayarre-Grau questionnaire and the level of knowledge of the disease by the Batalla test. The causes associated with adherence problems in these patients were identified. Results: non-adherence to antihypertensive therapy predominated in 62%. Partial adherence was found to be 22%. Adherence problems prevailed in women aged 60-69 years. Multiple causes related with the patient were detected, such as forgetfulness (48.4%), non-availability of medicines (25.8%) and relief of symptoms (16.1%). Among other causes, the low level of knowledge on the disease and the presence of comorbidities were detected. Conclusions: a predominance of adherence to antihypertensive treatment in older adults was evidenced. Its main causes were the forgetfulness of taking the medicine, the non-availability of medicines, the lack of knowledge about the disease and the presence of comorbidities (AU).

ABSTRACT

BACKGROUND: Pulmonary arterial hypertension (PAH) is characterized by elevated pulmonary arterial pressures and is managed by vasodilator therapies. Current guidelines encourage PAH management in specialty care centers (SCCs), but evidence is sparse regarding improvement in clinical outcomes and correlation to vasodilator use with referral. RESEARCH QUESTION: Is PAH management at SCCs associated with improved clinical outcomes? STUDY DESIGNAND METHODS: A single-center, retrospective study was performed at the University of Pittsburgh Medical Center (UPMC; overseeing 40 hospitals). Patients with PAH were identified between 2008 and 2018 and classified into an SCC or non-SCC cohort. Cox proportional hazard modeling was done to compare for all-cause mortality, as was negative binomial regression modeling for hospitalizations. Vasodilator therapy was included to adjust outcomes. RESULTS: Of 580 patients with PAH at UPMC, 455 (78%) were treated at the SCC, comprising a younger (58.8 vs 64.8 years; P < .001) and more often female (68.4% vs 51.2%; P < .001) population with more comorbidities without differences in race or income. SCC patients demonstrated improved survival (hazard ratio, 0.68; P = .012) and fewer hospitalizations (incidence ratio, 0.54; P < .001), and provided more frequent disease monitoring. Early patient referral to SCC (< 6 months from time of diagnosis) was associated with improved outcomes compared with non-SCC patients. SCC patients were more frequently prescribed vasodilators (P < .001) and carried more diagnostic PAH coding (P < .001). Vasodilators were associated with improved outcomes irrespective of location but without statistical significance when comparing between locations (P > .05). INTERPRETATION: The UPMC SCC demonstrated improved outcomes in mortality and hospitalizations. The SCC benefit was multifactorial, with more frequent vasodilator therapy and disease monitoring. These findings provide robust evidence for early and regular referral of patients with PAH to SCCs.

ABSTRACT

OBJECTIVE: To investigate racial and ethnic differences in pulmonary hypertension subtypes and survival differences in a pediatric population. STUDY DESIGN: This was a retrospective analysis of a cohort of patients with pulmonary hypertension (aged ≤18 years) enrolled in the Pediatric Pulmonary Hypertension Network registry between 2014 and 2018, comprising patients at eight Pediatric Centers throughout North America (n = 1417). RESULTS: Among children diagnosed after the neonatal period, pulmonary arterial hypertension was more prevalent among Asians (OR, 1.83; 95% CI, 1.21-2.79; P = .0045), lung disease-associated pulmonary hypertension among blacks (OR, 2.09; 95% CI, 1.48-2.95; P < .0001), idiopathic pulmonary arterial hypertension among whites (OR, 1.58; 95% CI, 1.06-2.41; P = .0289), and pulmonary veno-occlusive disease among Hispanics (OR, 6.11; 95% CI, 1.34-31.3; P = .0184). Among neonates, persistent pulmonary hypertension of the newborn (OR, 4.07; 95% CI, 1.54-10.0; P = .0029) and bronchopulmonary dysplasia (OR, 8.11; 95% CI, 3.28-19.8; P < .0001) were more prevalent among blacks, and congenital diaphragmatic hernia was more prevalent among whites (OR, 2.29; 95% CI, 1.25-4.18; P = .0070). An increased mortality risk was observed among blacks (HR, 1.99; 95% CI, 1.03-3.84; P = .0396), driven primarily by the heightened mortality risk among those with lung disease-associated pulmonary hypertension (HR, 2.84; 95% CI, 1.15-7.04; P = .0241). CONCLUSIONS: We found significant racial variability in the prevalence of pulmonary hypertension subtypes and survival outcomes among children with pulmonary hypertension. Given the substantial burden of this disease, further studies to validate phenotypic differences and to understand the underlying causes of survival disparities between racial and ethnic groups are warranted.

ABSTRACT

La hipertensión de la arteria pulmonar es una grave complicación que pueden presentar los pacientes con enfermedades autoinmunes del tejido conectivo Exis-ten distintas prevalencias reportadas según cada país. Por otro lado, la sobrevida de estos pacientes reportada al año y a los tres años, va desde 70-82% y 47-53% respectivamente dependiendo de cual es la enfermedad del tejido conectivo aso-ciada. En los últimos años se ha avanzado en la precocidad del diagnóstico y han aparecido nuevas terapias que han demostrado mejores resultados. Sin embargo, la respuesta al tratamiento sigue siendo mejor en pacientes con hipertensión pul-monar idiopática que en aquellas asociadas a enfermedad de tejido conectivo.


Pulmonary artery hypertension is a serious complication that may occur in pa-tients with autoimmune diseases of the connective tissue. There are different prevalence reported by country. On the other hand, the survival of these patients reported at one year and three years, going from 70-82% and 47-53% respec-tively, depending on which is the associated connective tissue disease. In recent years it has made progress in the precocity of diagnosis and new therapies have appearedthat have shown better results. However, the response to treatment is still better in patients with idiopathic pulmonary hypertension than in those associated with connective tissue disease.

ABSTRACT

La hipertensión de la arteria pulmonar (HAP) es una grave complicación que pue-den presentar los pacientes con enfermedades autoinmunes del tejido conectivo de prevalencia variable según cada país. Habitualmente su diagnóstico es tardío lo que influye negativamente en su pronóstico y respuesta terapéutica. En el pre-sente trabajo se ha iniciado una revisión en conjunto entre la Unidad de Hemodi-namia y de Reumatología del Hospital San Juan de Dios, con el propósito de tener una caracterización de los pacientes con HAP y enfermedades autoinmunes del tejido conectivo y poder así elaborar planes de manejo de acuerdo a las caracte-rísticas clínicas de estos pacientes e intentar obtener un diagnostico precoz, para mejorar la sobrevida de los portadores de estas enfermedades.


High blood pressure in the pulmonary artery (HAP) is a serious complication that may occur in patients with autoimmune diseases of the connective tissue of vari-able prevalence according to each country. Diagnosis is usually late which affects negatively their prognosis and therapeutic response. In the present work has been initiated a review in conjunction between the unit of Hemodynamic and Rheumatology of the Hospital San Juan de Dios, with the purpose of having a characterization of patients with PAH and autoimmune diseases of the connective tissue and can thus develop management plans according to the clinical features of these patients and try to get an early diagnosis, to improve the survival of the carriers of these diseases.
