iPhone app measured blood flow better in cardiac assessment

The researchers compared the use of a heart-rate monitoring application (the Instant Heart Rate application version 4.5.0 on an iPhone 4S)

Scientists have used an app on iPhone 4S to assess blood flow in a wrist artery for patients undergoing coronary angiography that performed better than the traditional physical examination. The smartphone app had a diagnostic accuracy of 94 percent compared with 84 percent using the traditional method.

Although this application is not certified at present for use in healthcare by any regulatory body, “our study highlights the potential for smartphone-based diagnostics to aid in clinical decision-making at the patient’s bedside,” said Dr Benjamin Hibbert from the University of Ottawa Heart Institute, Ottawa.

There are 29 types of blood groups in reality.
This test will help in assessing cardiac problems.

Researchers used the smartphone’s camera function to reach the conclusion, according to a randomised trial published in CMAJ (Canadian Medical Association Journal).

“Because of the widespread availability of smartphones, they are being used increasingly as point-of-care diagnostics in clinical settings with minimal or no cost,” said Hibbert.

“For example, built-in cameras with dedicated software or photodiode sensors using infrared light-emitting diodes have the potential to render smartphones into functional plethysmographs [instruments that measure changes in blood flow],” he added.

The researchers compared the use of a heart-rate monitoring application (the Instant Heart Rate application version 4.5.0 on an iPhone 4S) with the modified “Allen” test, which measures blood flow in the radial and ulnar arteries of the wrist, one of which is used to access the heart for coronary angiography.

A total of 438 participants were split into two groups. One group was assessed using the app and the other was assessed using the Allen test. “The current report highlights that a smartphone application can outperform the current standard of care and provide incremental diagnostic yield in clinical practice,” Dr Hibbert wrote.

“However, while smartphones aren’t designed as medical devices, it is important that they are evaluated in the same rigorous manner by which we assess all therapies and diagnostic tests,” noted lead author Dr Pietro Di Santo. IANS

In a fillip to Apple CEO Tim Cook’s big future plans for the Indian market, Apple has appointed Ashish Chowdhary, Chief Customer Operations Officer at Nokia Networks, as its India operation head, reliable industry sources told IANS on Tuesday.

Chowdhary will join as Apple India head from January next year, the sources confirmed.

The decision to hire Chowdhary is a testament to the fact that Apple is aiming for a really long-term growth in a price-sensitive market where Apple is an aspirational brand and usually bought by those who have high spending power or can go for older generation phones for affordability.

In line with the development, Nokia also announced on Tuesday changes in the composition of its group leadership team, declaring that Chowdhary will “leave Nokia at the end of 2018 after 15 successful years.”

“Chowdhary will continue to lead Customer Operations and remain a member of the Nokia Group Leadership Team until the end of 2018. He will then leave Nokia to take a leadership position in another company,” said Nokia.

According to industry sources, Apple has roped in Chowdhary — who has a sound global as well as local knowledge of the industry — to get a bigger slice of a market that has nearly 450 million users and is one of the fastest growing, after China and the US.

Apple India is currently under Michel Coulomb who took over from Sanjay Kaul in December last year.

Chowdhary has 25 years of international experience in the enterprise and telecom sectors. As Chief Business Officer, he was responsible for Nokia Networks’ sales and operations globally.

He has held various leadership positions, including Head of Asia Middle East and Africa and prior to that, Head of Global Services Business Unit.

Both these units contributed nearly half of the company’s revenues and were key to the successful transformation of Nokia.

The appointment comes at a time when the iPhone maker is seeking tax relief and other incentives from the government to begin assembling more handsets in the country and its proposal to set up a manufacturing unit is also being evaluated.

Breaking his silence on Apple’s India presence, CEO Tim Cook admitted on November 1 that his business was flat in the country in the fourth quarter amid weak currency trends.

Cook, however, stressed he is still a big believer in the Indian middle class.

The Apple CEO also said that he has had really great productive discussions with the Indian government.

“We’ve had really great productive discussions with the Indian government, and I fully expect that at some point, they will agree to allow us to bring our stores into the country,” Cook responded to a question during the analysts’ call.

“I am a big believer in India. I am very bullish on the country and the people and our ability to do well there,” Cook said.

Cook is also aware of the tremendous growth opportunity in India.

“There’s a huge number of people that will move into the middle class. The government has really focused on reform in a major way and made some very bold moves.

“I applaud them for doing that and I can’t wait for the future there,” Cook told the analysts over call. (IANS)
