The HYIMPACT study (IMPACT of Nebilet® in Blood Pressure Control in Patients with Hypertension) is a multinational, multicenter, observational, prospective, longitudinal real-world evidence study designed to assess the effectiveness and safety of Nebilet® (nebivolol) in hypertensive patients. The study aims to evaluate changes in systolic and diastolic blood pressure from baseline to 12, 24, and 36 months, as well as treatment adherence, quality of life, prescription patterns, and cardiovascular outcomes. A total of approximately 5,000 hypertensive patients with or without cardiovascular comorbidities will be enrolled across seven Asian countries (Malaysia, Indonesia, the Philippines, Korea, Vietnam, Thailand, and Taiwan). Patients newly initiated on Nebilet®-based treatment or already receiving Nebilet® for no more than two weeks prior to screening will be eligible for inclusion. Patients will be followed at regular intervals for up to three years. The study will also assess the correlation between home and office blood pressure measurements and compare Nebilet® monotherapy with combination therapy in achieving target blood pressure control. The findings from this study will provide real-world insights into the clinical management of hypertension with Nebilet® and its impact on patient outcomes.
