HEART & VASCULAR CARE
Looking after the heart and blood vessels of dialysis patients
Echocardiography, ECG and ankle–brachial index (ABI) testing
Alongside fluid balance and blood pressure, heart and blood-vessel health are important during ongoing dialysis care. We combine regular tests with day-to-day clinical assessment to review each patient’s condition.

Echocardiography: heart movement and valves
Echocardiography uses ultrasound to examine the movement, size and valves of the heart. At our clinic, we generally perform it one to three times a year for dialysis patients, adjusting the timing and frequency to each patient’s condition.
It also provides information that helps us assess fluid removal during dialysis.
We assess echo findings together with body weight, blood pressure and symptoms, considering fluid balance and the load on the heart when planning fluid removal.
ECG: checking the heart’s electrical activity
An electrocardiogram (ECG) records the heart’s electrical activity. It helps identify changes such as irregular heart rhythms, and can be compared with previous results.
At our clinic, ECG is performed once a year if no abnormalities are found.

ABI: assessing blood flow to the legs
The ankle–brachial index (ABI) compares blood pressure at the ankles and arms to check for reduced blood flow in the leg arteries. At our clinic, we generally measure ABI once or twice a year, adjusting the timing and frequency to each patient’s condition.
In dialysis patients, arterial calcification and other factors can limit the interpretation of ABI. A normal value does not always rule out arterial disease, so we also check symptoms and examine the feet.

Ultrasound of the neck or leg vessels when needed
We use vascular ultrasound of the neck or legs when symptoms or findings from examinations and tests indicate a need. The timing and combination of tests are considered individually.
If your condition changes
Should I wait for my next routine test if I have symptoms?
No. Please tell the care team about changes in your condition without waiting for the next routine test. We consider earlier or additional testing according to your symptoms and findings. Sudden severe chest pain or severe breathlessness requires emergency action, such as calling 119 in Japan.
CONSULTATION
Considering dialysis at our clinic?
We welcome enquiries about visits and transfers. Please call to tell us about your current dialysis care and any questions about attending our clinic.
