ABSTRACT

INTRODUCTION AND OBJECTIVES: Sleep apnea-hypopnea syndrome (SAHS) has been associated with different cardiovascular diseases. It may even be implicated in the pathophysiology of sick sinus syndrome (SSS). However, the precise relationship between the two syndromes is still unknown. We investigated the prevalence of SAHS in patients diagnosed with SSS. PATIENTS AND METHOD: Between June 2002 and December 2004, 38 consecutive patients who were diagnosed with SSS by 24-hour Holter monitoring were studied prospectively in our institution. All patients were asked about symptoms of SAHS, and underwent polysomnography out of hospital using a validated monitor. RESULTS: The patients' mean age was 67 (10) years, 68% were male, and 58% were hypertensive. Holter monitoring demonstrated a maximum heart rate of 87 (6) beats/min, a minimum of 35 (3) beats/min, and a mean of 48 (3) beats/min. Some 24 (63%) patients required pacemaker implantation because of symptomatic SSS. Overall, 39% of patients had symptoms suggestive of SAHS (i.e., an Epworth index or EI>9). Polysomnography showed that only 13% of patients had a normal apnea-hypopnea index (AHI) and that 31.6% (95% CI, 16.8%-46.4%) had SAHS (i.e., AIH>10 and EI>9). CONCLUSIONS: Given that the prevalence of SAHS in the general population is around 3%, our results indicate that it is ten-fold higher in patients with SSS than in the general population. This observation indicates that there may be a relationship between the two syndromes.

ABSTRACT

Introducción y objetivos. El síndrome de apnea-hipopnea del sueño (SAHS) ha sido relacionado con varias enfermedades cardiovasculares. Podría incluso estar implicado en la etiopatogenia de la disfunción sinusal (DS), aunque se desconoce la asociación real entre las 2 enfermedades. Pretendemos conocer la prevalencia del SAHS en enfermos diagnosticados de DS. Pacientes y método. Entre junio de 2002 y diciembre de 2004 se ha estudiado a 38 pacientes consecutivos diagnosticados de DS mediante registro Holter de 24 h. Todos fueron interrogados acerca de si presentaban síntomas relacionados con SAHS y se les hizo una polisomnografía respiratoria con un equipo validado. Resultados. La edad media de los 38 pacientes fue de 67 ± 10 años, el 68% era varón y el 58%, hipertenso. En el Holter la frecuencia máxima fue de 87 ± 6 lat/min, la mínima de 35 ± 3 lat/min y la media de 48 ± 3 lat/min. El 63% de los pacientes requirió marcapasos por DS sintomática. El 39% tenía somnolencia diurna excesiva (escala de Epworth [ESS] > 9). La polisomnografía demostró que sólo un 13% tenía un índice de apnea-hipopnea/h (IAH) normal y que el 31,6% (intervalo de confianza del 95%, 16,8-46,4) tenía un SAHS (IAH > 10 y ESS > 9). Conclusiones. Considerando que la prevalencia del SAHS en la población general es de alrededor del 3%, los resultados de nuestro estudio muestran que el SAHS es 10 veces más frecuente en pacientes con DS que en la población general, lo que indica una asociación entre las 2 enfermedades

ABSTRACT

FUNDAMENTO: Se analiza si un grupo de pacientes con enfermedad pulmonar obstructiva crónica (EPOC) posee información suficiente al respecto. PACIENTES Y MÉTODO: Entrevista estructurada sobre el conocimiento de la enfermedad, los deseos de información y de participación en las decisiones médicas y la opinión sobre las directrices anticipadas. RESULTADOS: Se entrevistaron 78 pacientes. El 92 por ciento sabía que sufría una enfermedad crónica y el 63 por ciento que era evolutiva, el 50 por ciento creyó que podría requerir un ingreso en una UCI y un 33 por ciento conocía la ventilación mecánica. Sólo el haber ingresado previamente en una UCI y ser portador de oxigenoterapia domiciliaria se relacionó con un mejor conocimiento de la enfermedad. Un 46 por ciento de los pacientes no se sentían informados, pero el 64 por ciento de ellos no deseaba más información. La mayoría desearía alguna forma de planificación futura de sus cuidados médicos en caso de incompetencia. CONCLUSIONES: El paciente afectado de EPOC no dispone de información para tomar decisiones autónomas, y aún menos de forma anticipada. El conocimiento lo da la experiencia previa con dicha enfermedad y sus complicaciones (AU)
