Personal solution
for hypertension management



CART BP automatically and continuously collects blood pressure data from the ring


Able to track blood pressure variability through the mobile app linked to the ring


The collected blood pressure data is transmitted to a cloud server for analysis with deep learning algorithms


Personalized report to provide an overview of blood pressure health

Unlike traditional cuff-based blood pressure monitors, CART BP uses PPG sensors to measure ² blood pressure in a cuffless manner, enabling continuous monitoring day and night.

Morning hypertension ³

Nocturnal hypertension

is a strong risk factor for cardiovascular disease

increases incidence rate of stroke

Nighttime blood pressure monitoring

Untreated hypertension increases ³ the risk of heart attack and stroke by triggering nocturnal hypertension.

Considering that blood pressure varies throughout the day, intermittent measurement at the office doesn't provide sufficient information for diagnosing hypertension. It is important to keep track of day and night blood pressure levels.

Korean Society of Hypertension Guidelines for the management of hypertension 2022

If high blood pressure persists, it can lead to damage in blood vessels, resulting in arteriosclerosis. This condition may cause myocardial infarction, heart failure, stroke, and chronic kidney disease. Continuous blood pressure monitoring is essential for preventing and diagnosing hypertension.

Nighttime Blood Pressure Monitoring

Evaluate nocturnal hypertension / morning surge / daytime blood pressure variability

Reverse dipper or riser

Nighttime BP is relatively riser than daytime ⁵ ⁶ ⁷

Associated with autonomic abnormalities and increased risk of cardiovascular events such as hemorrhagic stroke and death ⁹


Nighttime BP is less 10% lower than daytime ⁹ ¹⁰

Increased left ventricular hypertrophy, myocardial ischemia, mortality ⁶


Nighttime BP is 10~20% lower than daytime

Extreme dipper

Nighttime BP is over 20% lower than daytime ⁸ ¹¹

Increased risk of ischemic stroke and atherosclerosis ⁷ ¹²

Morning surge

BP is riser in the morning

Risk factors for cardiovascular disease, especially stroke ¹²

Factors causing nocturnal hypertension from hypertensive patients ¹³

No clinical significance has been known to date in generally healthy individuals with normal blood pressure.
