Sky Labs' CART BP pro, a finger-worn ring that measures blood pressure continuously without a cuff, has secured reimbursement and prescribing volume in Korea and is entering European distribution ahead of a planned US de novo submission to the FDA. The Korean Society of Hypertension has already recommended validated cuffless devices, an unusually rapid guideline response. Continuous, tolerable blood pressure measurement addresses the central weakness of episodic office readings, which miss the nocturnal and variability patterns most predictive of cardiovascular and cerebrovascular risk.
Key Points
- Cuffless finger ring measures blood pressure continuously, replacing 24-hour ambulatory cuffs
- Korean reimbursement and prescribing data now anchor European and US expansion
- US clinical study underway; FDA de novo pathway targeted for 2026
Longevity Analysis
Blood pressure is among the most modifiable determinants of vascular aging, yet the standard measurement method captures a few seconds of a continuously fluctuating variable. Nocturnal dipping patterns, morning surges and day-to-day variability carry independent prognostic weight for stroke, kidney decline and cognitive trajectory, and none of them are visible in a clinic reading. Wearable formats that patients tolerate for weeks rather than hours shift hypertension management from periodic snapshots toward genuine pattern recognition, allowing interventions in sleep, stress load, sodium handling and training intensity to be evaluated against the vascular response they actually produce.
