Advances in Multimodal Echocardiographic Evaluation of Ischemic Cardiomyopathy due to Obstructive Sleep Apnea Syndrome.

Obstructive sleep apnea syndrome (OSAS) is characterized by recurrent complete (apneas) and partial (hypopneas) upper airway events, causing intermittent hypoxemia and sleep fragmentation. It significantly impacts the cardiovascular system, increasing the morbidity and mortality associated with various complications. Therefore, employing appropriate echocardiographic methods to assess myocardial function in OSAS patients is crucial. It can facilitate early clinical intervention, enhance the quality of life, and potentially extend patients' survival.
