Özet

Awareness of the significance of sleep-related disorders in cardiovascular diseases is increasing. Sleep disorders are common in heart failure, involving insomnia, disruptions in sleep architecture, periodic leg movements, and periodic breathing. Difficulties in initiating or maintaining sleep, early awakening, difficulty returning to sleep, and daytime sleepiness are frequently observed. In our study, we aimed to investigate polysomnographic differences in sleep architecture in patients with chronic, compensated, and stable heart failure and to reveal the relationship between these changes and left ventricular systolic function through polysomnography and transthoracic echocardiography. Patients between the ages of 18-75 with complaints of sleep disturbances, evaluated through Transthoracic Echocardiography, will be included in the study. A prerequisite for inclusion will be receiving optimal Heart Failure treatment for at least four weeks. Exclusion criteria will include chronic heart failure due to valvular heart diseases, listing for heart transplantation, known life-threatening diseases, current treatment with oxygen or positive airway pressure, and a history of unstable angina pectoris, acute myocardial infarction, and cardiac surgery within the last 3 months. In heart failure patients, the percentage of stage N1, total AHI, total RDI, total RERA, total obstructive apnea events, total desaturation duration, total arousal index, AHI, RERA, and RDI independent of position during NREM sleep, RDI independent of position during REM, and AHI in the supine position were higher compared to the control group. Heart failure, even in its early stages, warrants attention regarding sleep disorders. Emphasizing the timely and accurate identification, treatment of sleep and respiratory disorders in heart failure patients, considering the potential positive impact on long-term outcomes, is crucial.
