Cetia keeps your heart care joined up, from home to every clinic you visit, so your time with your doctor is spent on what matters.
Cetia is in development and testing. Cetia is NOT yet a registered medical device.
It's silent. It's slow. And the current system is not built to catch it, especially for the patients most likely to be left behind.

A single blood pressure reading tells you about that day. What matters most is what your heart is doing over time. At different times of day. Without the stress of being at the clinic. Seeing the impact of your medication.
GPs know this. NICE guidelines now recommend home monitoring as the standard for diagnosis and management. But the infrastructure to collect, interpret, and act on that data at scale, without creating more work for already stretched clinical teams, doesn't yet exist.
Cetia is built to close that gap.
adults in England are living with high blood pressure and don't know it. Many are younger, feel well, and have no reason to suspect anything is wrong. Too often it is only found when something goes wrong. Measuring at home is how people find out sooner.

Write down what you want to talk about before you go, so nothing is forgotten on the day. Your care team sees what matters to you, in your words, and the time together is spent on it.
Scan your readings at home and they stay stored in your account. Then write down what you want to talk about and choose which readings go with it.
On clinic day, your clinician opens “What Sana would like to discuss”: your notes in your words, with the readings you chose.
The clinic pack goes into your clinician’s records, and your appointment shows “Seen in clinic”.
Scan or enter your blood pressure readings right from your phone, using any blood pressure device. Weight and walking too, if you use them. The iPhone app works offline, so a reading is never lost.
Patients plan for their appointments and share what matters. Clinicians see, on the day, what each patient would like to discuss. Your heart care stays joined up, whichever clinic you are in.
Before you go, write down what you want to talk about. Four simple questions, each with an example, saved as you type. Nothing to remember on the day.
Scan or enter your readings as you take them. Log when you take your medication, and when you don't. Missed doses, side effects, stopping and restarting. This context is as important as the reading itself.
Only you can see your appointment until you share it. Tick who in your care team can see it, and untick to stop. See exactly what they will see.
Invite a family member or carer to your care circle. They can see your readings, get your reading reminders, and support you, without being overwhelmed with clinical detail.

What Sana would like to discuss
In Sana's words
I've been short of breath going up the stairs since the summer.
I'm worried my medication Amlodipine 5mg isn't right.
I last felt well before my holiday in August.

Cetia is designed alongside GPs, practice nurses and hospital consultants, for the way NHS clinics actually run, and for the patients they see.
Designed with clinicians in primary and secondary care, and with patients living with cardiovascular disease.
Only you can see your appointment until you share it. You choose who in your care team sees it, and can stop at any time.
Full accessibility compliance.
“At home BP monitoring is a top-priority clinical need, and a daily workflow pain. We get readings by phone call, then manually type them into EMIS. That data is often lost.”

“NICE guidelines are now a forcing function. Home readings are preferred, but the infrastructure to act on them doesn't exist in primary care.”
GP · South East England
“Longitudinal home data could help us make better and faster decisions. We see complex patients, but we can't see the data-driven picture between visits.”
Cardiologist Consultant · Secondary Care
NICE guidelines recommend ambulatory or home blood pressure monitoring as the standard for hypertension diagnosis and management. Cetia supports clinicians in delivering exactly this, without adding to their workload.
Cetia is built around the patient’s real life. Time at home, time at the GP, and time at the hospital. It joins the gaps between home, primary and secondary care settings, which feel disjointed and frustrating for all.
Trial co-design is underway with our advisory board to generate the evidence base required for full NHS commissioning. If you are a GP practice, PCN, or NHS trust interested in participating, we want to hear from you.
Cardiovascular disease is the leading cause of premature death in the UK, and its burden falls unequally. People from South Asian and Black communities face significantly elevated CVD risk, often compounded by systemic barriers to diagnosis and treatment. Women are underrepresented in the clinical research that underpins the guidelines clinicians use today. Patients in more deprived areas, those with lower health literacy, and those whose first language is not English face additional friction at every step of the care pathway.
Cetia's long-term vision is a world where no preventable cardiovascular death or disability happens because the right data wasn't available, the right person wasn't represented, or the right action wasn't taken. Regardless of gender, ethnicity, age, or postcode.
Equitable access is a specification requirement, not a feature. Cetia is built with WCAG 2.1 AA accessibility, offline-first design, and a patient experience built for people with low health literacy, because those are the patients who need it most.
