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

Apple lost over $60 billion in market cap in two days after Taiwan Semiconductor, Apple’s biggest supplier, said in an earnings update that second-quarter revenues would be hit by “weak demand from the mobile sector”.

Apple shares fell nearly seven per cent on Thursday and Friday over reports of a sharper slowdown in smartphone sales this year, Financial Times reported late on Friday.

Not just Apple, the news led to several global chipmakers losing market valus, including Analogue Devices, Dialog Semiconductor, Qualcomm and Qorvo.

For the first time since 2009, smartphone sales in China fell last year while global sales fell in the fourth quarter of 2017 for the first time since 2004.

In another setback for the iPhone maker, its efforts to get LG Display’s OLED screens for future iPhone production line “have hit manufacturing issues”, the Wall Street Journal reported on Friday.

Apple is reportedly divided on whether LG will be able to succeed as Samsung’s replacement for OLED displays.

The Cupertino-based company currently uses Samsung’s OLED displays for iPhone X.

The LCD panels which are currently being used in the iPhone 8 and iPhone 8 Plus are supplied by LG. Apple Watch screen is made by LG Display.

There are reports that Apple is designing and producing its own device screens, secretly at a facility near its headquarters in California.

It is believed that Apple will switch to OLED displays for all of its iPhone releasing in 2019.  IANS
