RESUMO
RESUMO Pacientes oncológicos desenvolvem problemas cardíacos frequentes devido à toxidade dos quimioterápicos, com consequente impacto na capacidade funcional (CF) e na qualidade de vida (QV). O treinamento muscular inspiratório (TMI) pode ser um recurso terapêutico viável, já que estudos de causa-efeito demonstraram melhora da CF e da QV em outras populações. Contudo, seu efeito ainda não foi avaliado em pacientes cardio-oncológicos. Assim, o objetivo deste estudo foi descrever o efeito de um programa de TMI sobre a CF e a QV de uma paciente com cardiotoxicidade: LDM, com 41 anos, mulher e sedentária, que desenvolveu insuficiência cardíaca após tratamento quimioterápico. A QV foi avaliada pelo teste de Minnesota. Foram avaliados também a força muscular inspiratória dinâmica (S-Index) e o limiar glicêmico (LG) dos músculos inspiratórios. O LG foi determinado pela glicemia capilar por meio do glicosímetro digital (Accu-Chek - Roche) no menor valor da glicemia da carga correspondente ao teste muscular inspiratório incremental (TMII). A progressão da carga foi realizada a cada duas semanas. Ao final de dois meses, todos os testes foram reaplicados. No teste de Minnesota, os valores relacionados à CF, antes e após o TMI, foram de 36 vs. 8 (melhora de 78%); aos aspectos clínicos e psicológicos foram de 32 vs. 7 (melhora de 78%), a S-Index foram de 41 vs. 51cmH2O (melhora de 24%). O TMI melhorou a CF e a QV de uma paciente cardio-oncológica, configurando-se como um recurso terapêutico viável para essa população.
RESUMEN Los pacientes con cáncer desarrollan problemas cardíacos frecuentes debido a la cardiotoxicidad de la quimioterapia, con el consiguiente impacto en la capacidad funcional (FC) y la calidad de vida (CV). El entrenamiento muscular inspiratorio (IMT) puede ser un recurso terapéutico viable, ya que los estudios de causa-efecto han demostrado una mejora en la FC y la CV en otras poblaciones. Sin embargo, su efecto aún no se ha evaluado en pacientes cardio-oncológicos. Por lo tanto, el objetivo de este estudio fue describir el efecto de un programa de IMT sobre la FC y la CV de un paciente con cardiotoxicidad: LDM, 41 años, mujer y sedentaria, que desarrolló insuficiencia cardíaca después del tratamiento de quimioterapia. La CV se evaluó mediante la prueba de Minnesota. También se evaluaron la fuerza muscular inspiratoria dinámica (índice S) y el umbral glucémico (LG) de los músculos inspiratorios. El LG se determinó por glucemia capilar mediante el glucómetro digital (Accu-Chek - Roche) al valor más bajo de la carga glucélica correspondiente a la prueba muscular inspiratoria incremental (IMI). La progresión de la carga se realizó cada dos semanas. Después de dos meses, todas las pruebas se volvieron a aplicar. En la prueba de Minnesota, los valores relacionados con la FC, antes y después de THE, fueron 36 vs. 8 (78% de mejora); los aspectos clínicos y psicológicos fueron 32 vs. 7 (mejora del 78%), el índice S fue de 41 vs. 51cmH2O (mejora del 24%). El IMT mejoró la FC y la CV de un paciente cardio-oncológico, constituyendo un recurso terapéutico viable para esta población.
ABSTRACT Cancer patients develop frequent cardiac problems due to chemotherapy toxicity, which impacts functional capacity (FC) and quality of life (QoL). Inspiratory Muscle Training (IMT) may be a viable therapeutic resource since cause-effect studies have shown improvement in FC and QoL in other populations. However, its effect was not evaluated in cardio-oncology patients. The study aimed to describe the effect of an IMT program on the FC and QoL of a patient with cardiotoxicity, LDM, aged 41 years, female and, sedentary that developed heart failure after chemotherapy. The QoL was evaluated by the Minnesota test. Dynamic Inspiratory Muscle Strength (S-Index) and Glycemic Threshold (GT) of the inspiratory muscles were also evaluated. The GT was determined by capillary glycemia with a digital glucometer (Accu-Chek - Roche), at the lowest value of glycemia of the load corresponding to the Incremental Inspiratory Muscle Test (IIMT). The load progression was performed every two weeks. After two months, all tests were reapplied. In the Minnesota test, the values related to FC, pre and post IMT, were 36 v. 8 (78% improvement); the clinical and psychological aspects 32 v. 7 (78% improvement); S-Index was 41 v. 51cmH2O (24% improvement). IMT improved the FC and QoL of a cardio-oncology patient, configuring itself as a possible and viable therapeutic resource for this population.
RESUMO
Introduction and objective: Sickle cell anemia (SCA) is a genetic condition that alters the conformation of deoxygenated red blood cells, which results in their stiffening and the occurrence of vaso-occlusive crises, endothelium damage, organ dysfunction and systemic complications. Additionally, SCA limits the participation of individuals in physical and social activities. As we consider that physical exercise promotes the recovery of functional capacity and cardiorespiratory conditioning, we aim to verify the patterns of prescription, the effects and safety of exercise for individuals with SCA. Methodology: We systematically reviewed the published literature focusing on clinical trials that correlated physical exercise with SCA patients and cross-sectional studies that applied the stress test. The data research was based on the PRISMA recommendations and the following databases were used: Medline by PubMed, Cochrane, PEDro, Scielo. Results: Six studies which were based on the evaluation of 212 patients aged between 13 and 40 years, were selected from 122 identified studies. Those studies associated the individual effort tolerance improvement, its inflammatory profile adjustment and the absence of alteration in the autonomic nervous system activity to physical exercise or stress test. Conclusion: Low-to-moderate intensity physical exercise increased the SCA individual tolerance without causing vaso-occlusive crises, nor changes in the hemorheological and inflammatory profiles.
