Wireless device to detect heart dysfunction in cancer survivors
New York, June 23 : Scientists have designed a novel wireless device which may accurately detect heart dysfunction in children who have survived cancer.
Childhood cancer survivors are advised to undergo screening for the detection of heart dysfunction because of known anthracycline-induced cardiotoxicity.
However, screening with echocardiography -- the standard of care for monitoring heart function -- can be highly variable and limited.
Another alternative is cardiac magnetic resonance (CMR) imaging, which is expensive and is not widely accessible.
In the study, the team tested Vivio -- a prototype handheld instrument which collects pulse waves and phonocardiogram data from the carotid artery. The results showed that the device was accurate and it displayed a low false-negative rate as compared to CMR imaging.
"This study is the first step in thinking about new paradigms of long-term monitoring and care delivery for cancer survivors who are at risk for severe and life-threatening health conditions," said Saro Armenian, Director at City of Hope National Medical Centre in California.
The study, published in the journal Clinical Cancer Research, involved data from 191 patients exposed to anthracycline chemotherapy.
The data of the participants was collected using Vivio which then streamed wirelessly to a compatible device such as a smart phone or e-tablet.
This mobile health platform negates the need for result interpretation and allows for real-time monitoring of heart health, explained Armenian.
Using a specialised algorithm, Vivio measures the left ventricular ejection fraction (LVEF), which is commonly used to assess heart function and measures the percentage of blood ejected from the left ventricle of the heart, Armenian added.
However, the author said that Vivio is not currently intended to replace echocardiography or CMR imaging.
"One possible implementation of Vivio could be for preliminary screening," Armenian explained.

Rahul Gandhi to join Congress padyatra in Bihar, address party workers
Patna (PTI): Leader of the Opposition in Lok Sabha, Rahul Gandhi, will join the party's ongoing 'Palayan Roko, Naukri Do' padyatra in Bihar's Begusarai district on Monday.
Later in the day, he will return to Patna from Begusarai to address the 'Samvidhan Suraksha Sammelan' (Save the Constitution Symposium). After that he will visit Sadaqat Ashram, the Bihar Congress office in Patna, to address party workers.
This will be Gandhi's third Bihar tour since January, when he had urged party workers to "inflict an ideological defeat" on the BJP in the assembly polls due later this year.
The Raebareli MP shared a minute-long video message on X on Sunday, urging the youth of Bihar to join him in the march in Begusarai wearing "white T-shirts".
"Our aim is to draw the attention of the world to the plight of Bihar's youth, who find government jobs getting scarce day by day and privatisation bringing no benefits. Let us bring the government in the state under pressure and change it," he said in the video.
Begusarai also happens to be the home district of Kanhaiya Kumar, who has been the star attraction of the padyatra, which began in East Champaran district last month.
The former JNU students' union president had unsuccessfully contested the 2019 Lok Sabha polls, on a CPI ticket, from the seat.
In the Bihar assembly polls, the Mahagathbandhan, comprising RJD, Congress and the Left, is pitted against the ruling Nitish Kumar-led NDA that also comprises the BJP.
