ABSTRACT
PURPOSE: Many patients with acute coronary syndrome experience problematic or altered sexual function. This aspect of the disease is frequently ignored or overlooked by the healthcare community even though it can strongly influence health-related patient quality of life (HRQoL). Thus, the aim of this study was to compare the effects of a specific cardiac rehabilitation programme focused on aerobic and neuromuscular strength-resistance training to those of a classic rehabilitation programme, both in terms of HRQoL and erectile dysfunction in patients with acute coronary syndrome. METHODS: This study reports both secondary and unregistered outcomes from a double-blinded, randomised, and controlled clinical trial. The proposed intervention was based on the completion of a 20-session (10-week) cardiac rehabilitation programme for patients with cardiovascular disease. The patient cohort had been diagnosed with acute coronary syndrome and was recruited at the Cardiology Service of a private tertiary hospital. The outcomes assessed in this study were HRQoL and erectile disfunction assessed at baseline, after the intervention, and at a 6-month follow-up. RESULTS: A total of 30 participants were randomly allocated to each study arm. The results of the two-way mixed ANOVAs showed significant group × time interactions for all the outcome measures (EQ-5D_index, p = 0.004; EQ-5D_VAS, p = 0.017; QLMI-Q, p ≤ 0.001; and IIEF-5, p = 0.001). CONCLUSION: The neuromuscular strength training programme was more effective than the classic strength training programme in terms of increasing the HRQoL and improving erectile dysfunction in patients following acute coronary syndrome, with differences still remaining between these groups at the 6-month follow-up.

Objetivo El objetivo fundamental de este estudio es comprobar si existe correlación entre el resultado de la prueba de 6min marcha y el consumo de oxígeno obtenido en una prueba de esfuerzo mediante cicloergometría en sujetos sanos de entre 20 y 30 años aproximadamente.Material y métodoLa muestra del estudio comprendió 22 sujetos, con una edad media de 24,4±2,6 años. Las medidas antropométricas recogidas fueron peso corporal, diámetros óseos, altura y pliegues cutáneos. Realizaron una prueba de esfuerzo máxima en cicloergómetro, con determinación de consumo pico de oxígeno (VO2pico). Se realizó también la prueba de 6min marcha. A todos los sujetos se les mostró una escala de esfuerzo percibido (escala de Borg) con valores entre 6 (muy muy leve) y 20 (muy, muy duro). El análisis estadístico consistió en la prueba de correlación de Pearson entre las variables de interés, y la prueba t de Student para muestras relacionadas. Se consideró significativa un p<0,05.ResultadosLas correlaciones más altas se encontraron entre la distancia recorrida en la prueba de 6min marcha y el VO2pico ml/min de la prueba de esfuerzo (r=0,83; p<0,01; n=21). El resultado del trabajo en la prueba de 6min marcha, calculado como distancia recorrida por peso muscular medido con antropometría, presentó la mayor correlación con el VO2pico en la prueba de esfuerzo VO2pico ml/min (r=0,88; p<0,01; n=21)(AU)
Objective The primary aim of this study was to find out if there is a correlation between the results on a 6min walking test and peak oxygen consumption achieved in an exercise test using the cycle-ergometer in healthy subjects of approximately 2030 years of age.Material and methodsThe simple included 22 subjects, mean age 24.4±2.6 years. The anthropometric measures recorded were weight, bone diameters and height and skin folds. All underwent a cycle-ergometer graded exercise test to determine VO2 peak, and the 6min walking test. All of the subjects were shown a perceived exertion scale (Borg scale) with values going from 6 (very very light) to 20 (very, very hard). The statistical analysis consisted of the Pearson correlation between main variables and the Student's T test for paired samples. Significance was determined at p<0.05.ResultsThe highest correlations were those of distance walked in the 6min walking test and VO2 peak ml/min (r=0.83; p<0.01; n=21). The work result in the 6min walking test (kg of muscle weight from anthropometry per meters covered) showed greater correlation with VO2 peak consumption on the VO2 peak ml/min exertion test ml/min (r=0.88; p<0.01; n=21)(AU)
