| الوصف: | Introducao : A apneia obstrutiva do sono (AOS) afeta a anatomia e funcao do coracao. Ocorre hipertensao arterial em metade dos casos de AOS, dificultando atribuir a etiologia dessas alteracoes separadamente a hipertensao arterial ou a apneia do sono. Metodos : Estudo transversal de pacientes com indice de apneia-hipopneia maior que 50 eventos por hora. As variaveis ecocardiograficas comparadas em individuos com hipertensao arterial controlada e nao controlada foram: 1) fracao de ejecao, 2) diâmetro da aorta, 3) diâmetro do atrio esquerdo, 4) diâmetro de ventriculo direito, 5) diâmetros do ventriculo esquerdo diastolico e sistolico, 6) percentagem delta, 7) espessura do septo, 8) espessura da parede posterior. Resultados : Foram incluidos 83 voluntarios, 50 com pressao arterial nao controlada. Em media, a idade era 47±9,5 anos, o indice de massa corporal 34±5,4 Kg/m 2 , o indice de apneia-hipopneia 86±18 eventos/hora. Sessenta pacientes apresentaram anormalidade no ecocardiograma. A hipertrofia de ventriculo esquerdo foi o achado mais comum, sem diferenca de frequencia em controles (39%) e em hipertensos (48%), seguida por disfuncao diastolica em controles (27%) e em hipertensos (32%). Conclusoes : Individuos com apneia do sono grave e pressao arterial controlada apresentam alteracoes no ecocardiograma de tipo e frequencia semelhantes aos com hipertensao nao controlada. Isso sugere que a apneia do sono pode causar dano cardiaco independentemente de hipertensao. Quando nao explicaveis por hipertensao arterial, achados como hipertrofia de ventriculo esquerdo podem ser provocados por apneia do sono. Introduction: Obstructive sleep apnea (OSA) affects the cardiac anatomy and function. Hypertension occurs in half the OSA cases, making it difficult to attribute the cause of these changes separately to arterial hypertension or sleep apnea. Methods: Prospective cross-sectional study of volunteers with apnea-hypopnea index >50 events per hour. The echocardiographic variables were analyzed: 1) ejection fraction, 2) aortic diameter, 3) left atrial diameter, 4) right ventricular diameter, 5) diastolic and systolic diameters of the left ventricle, 6) delta percentage, 7) septum thickness, 8) posterior wall thickness. Results: There were 83 participants, 74 men, 50 with hypertension. The average age was 47±9.5 years, body mass index of 34±5.4 kg/m 2 , apnea-hypopnea index of 86±18 events/hour, and minimum oxygen saturation of 55±17%. Left ventricular hypertrophy was the most common echocardiographic abnormality in subjects without hypertension (39%) and with hypertension (48%), followed by diastolic dysfunction in subjects with normal blood pressure (27%) and with high blood pressure (32%). There was no statistically significant difference in echocardiographic characteristics between hypertensive subjects with those with normal pressure. Conclusions: Individuals with normal blood pressure and severe sleep apnea show abnormalities in the echocardiogram with frequency similar to that observed in patients with high blood pressure. This suggests that sleep apnea can cause ventricular overload independently of hypertension. When not explained by high blood pressure, left ventricular hypertrophy can be caused by sleep apnea. |
