Blood pressure control is the single most important thing you can do to prevent a second stroke. I have tracked mine twice daily for seven years. Here is the monitor I trust and why.
This is written by Nick Kremers, who was paralyzed by a stroke, spent three years in a wheelchair, and rebuilt his way back to walking, typing, and training again. He built Stroke Recovery Academy out of that wheelchair, and everything on this page is filtered through what actually worked in his own recovery and the recoveries of the survivors he now coaches.

Upper-arm cuff with validated accuracy (AAMI/ESH), irregular heartbeat detection, and memory for 60+ readings. The same type I have used twice daily for seven years.

Hypertension is the single largest modifiable risk factor for both first and recurrent strokes. After my hemorrhagic stroke, my neurologist set a target of under 130/80. I have hit that target for six years straight. The only way I know I am hitting it is by measuring at home.
Clinic measurements are snapshots. They are taken in a medical setting, often with white-coat anxiety, and they happen once every few months. Home measurements are a movie. They show trends, morning spikes, evening dips, and the effect of yesterday's salt. If you are serious about preventing a second stroke, you need the movie.
Not all monitors are accurate enough for medical decision-making. Look for these four features: validated accuracy (validated against a clinical standard like AAMI/ESH), upper-arm cuff (wrist monitors are less accurate), memory storage (at least 60 readings), and an irregular heartbeat indicator (survivors with AFib need this).

I sit with back supported, feet flat, arm at heart level. I take two readings one minute apart and record the average.
I bring a month of readings to every appointment. My doctor uses the home data to adjust medication, not the single clinic reading. The home data has caught medication issues that the clinic missed. It is the most important tool in my prevention kit.
A single reading tells you almost nothing. Two weeks of readings tells you something. Six months of readings tells you everything. Here is what to look for in the trend data:
Morning surge: a spike in systolic BP in the first hour after waking — higher than evening readings — is called morning surge and significantly increases stroke risk. It is often invisible without home monitoring. If your morning reading is consistently 15–20 points higher than your evening reading, mention it to your neurologist.
Nocturnal pattern: some monitors have a night mode or can be read with a timestamp. Non-dippers (people whose BP does not drop at night) have higher stroke risk than dippers. CPAP therapy often converts non-dippers to dippers — another reason to treat sleep apnea if you have it.
Medication timing: if your evening readings are much higher than morning readings, your once-daily medication may be wearing off. Your prescriber can time the dose differently or add a second agent. If your reading is highest 30 minutes after taking your medication, that is a false peak and not clinically meaningful. Track both timing and reading.
Most stroke survivors should aim for under 130/80. Hemorrhagic stroke survivors may need even tighter control. Your neurologist sets the target — track toward it, not a generic number.
Twice daily is the standard for the first year after stroke. Once daily is acceptable if your readings are stable for six months. Never less than three times per week.
Wrist monitors are less accurate than upper-arm cuffs because the wrist is farther from the heart and position changes affect the reading. Use an upper-arm cuff unless you have a medical reason not to.
Yes. Bring the monitor and a month of readings. Your doctor can compare your device against the clinic device to verify accuracy. This is called cross-validation and it is standard practice.
