Core Tip
Core Tip: Obstructive sleep apnea (OSA) is increasingly recognized as a contributor to cardiovascular morbidity, including pulmonary hypertension (PH). This present cross-sectional study aimed to assess the prevalence and severity of PH in newly diagnosed OSA patients. Furthermore, it assessed its association with disease severity and quality of life (QoL). PH is a prevalent and underdiagnosed complication of OSA that negatively impacts QoL. There is an imminent need for integration of echocardiographic screening and QoL assessments into the routine management of OSA.
