Hypertension remains suboptimally controlled despite combination pharmacotherapy, and office blood pressure measurements may not adequately reflect true ambulatory blood pressure burden and nocturnal patterns. CART BP pro is a wearable, cuffless photoplethysmography-based continuous blood pressure monitoring device. This study investigates whether a CART BP pro-guided antihypertensive titration strategy improves 24-hour ambulatory blood pressure control compared with usual care in real-world outpatient settings. Participants receive standard antihypertensive medications (e.g., angiotensin receptor blocker \[ARB\], calcium channel blocker \[CCB\], thiazide diuretic) per guideline-based care. In the CART BP pro-guided group, medication adjustments are informed by CART BP pro-derived 24-hour blood pressure data. Follow-up is 24 weeks with optional extended follow-up to 48 weeks.
