In the United States an estimated 48% of adults or 121.5 million people, have some form of cardiovascular disease according to the American Heart Association. Cardiovascular diseases which include heart attack and stroke are the No.
1 killer worldwide, responsible for about 32% of global deaths. The risk of these deaths can be reduced with earlier detection.
Now, a 14-year-old from Frisco, Texas, has developed a ground-breaking smartphone app to detect early signs of heart disease in just seven seconds.
Circadian AI, the app records heart sounds, filters out ambient noise and analyses the data using a cloud-based machine learning model- all by placing a smartphone near the chest.
The app identifies arrhythmias, irregular heartbeats, early signs of heart failure, indicators of coronary artery disease and heart valve abnormalities.
Siddharth Nandyala's motivation stemmed from his desire to use AI to help people and revolutionize the healthcare system. 'What really took my interest in the healthcare side of artificial intelligence was the sheer amount of impact and the change that can be made,' he told the Smithsonian magazine.

He spent months gathering data from hospitals in the US and India and collaborated with medical professionals and patients to refine his app. The clinical trials for his app involved approximately 15,000 patients in the US and around 3,500 in India with the app achieving over 96% accuracy in detecting heart abnormalities, as per Nandyala.
Currently, the app is intended only for clinical use by trained personnel, as it requires proper understanding to operate effectively.
Nandyala emphasized that it is a pre-screening tool and not a replacement for traditional diagnostic methods like EKGs.
Medical professionals praised the app's potential to advance medical care, especially in areas with limited access to healthcare.
'An early potential diagnosis in patients who otherwise may not have had access to medical care may ultimately reduce long-term morbidity and mortality from this condition,' Jameel Ahmed, an electrophysiologist at Louisiana State University, told the magazine.
For the 14-year-old, this is not his first innovative work of technology. He previously designed a low-cost prosthetic arm and founded STEM IT- a startup that creates science and technology kits for students.
His work has earned him a Certificate of Recognition from the US House of Representatives and a letter of congratulations from then-President
Joe Biden

The young innovator is already a freshman studying computer science at the University of Texas. He hopes to expand the app's capabilities to detect lung-related illnesses pneumonia and pulmonary embolism using similar techniques.

Goa health minister Rane abuses, threatens GMC doc on camera, sparks furore
Panaji: Health minister Vishwajit Rane on Saturday directed the immediate suspension of an on-duty chief medical officer (CMO) at Goa Medical College's casualty department. Rane's move followed a complaint alleging that the doctor told a patient to go to an urban health centre to receive an injection. In a video widely shared on social media, Rane is seen telling the senior doctor to 'go home' and 'shut up', and issued directions to 'kick him out of here'. When the doctor tried to respond, Rane told him, 'You are not authorised to speak when I am speaking' and 'first learn to shut up when I am talking to you', before telling him to 'get out from here'. As the doctor tried to reason with the minister, Rane said, 'When I make up my mind, I don't want to listen to you. .. 'Don't open your mouth when I'm talking.' 'You're dealing with me. You want to file a case, file a case,' Rane told the doctor, adding, 'go home before my blood pressure boils'. The video clip angered netizens, who didn't appreciate the minister's 'herogiri' and slammed him. They alleged that while he was preaching to the doctor to serve the poor, as TCP minister, he allegedly serves the rich from Delhi-NCR and Haryana, and thus has no moral right to preach. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Lake Mary: How Much Does It Cost To Install Windows In 2025?

The complaint that sparked the minister's reaction related to a 77-year-old woman and her daughter, relatives of a journalist, who went to GMC on Saturday to receive an injection for the knee. The orthopaedic patient was told she was required to take the injection every day for ten days, Saturday being the fourth day. As OPDs were closed on Saturday, the patient was asked to go to GMC's casualty department, where the CMO allegedly didn't guide the patient properly, and told her to go to the urban health centre for the injection. Rane lectured the doctor on how to talk to patients, and not send them from pillar to post but to guide them properly. He told the doctor he was at GMC to 'serve poor people'. 'However much loaded you are, you will talk properly and guide the patient,' Rane said, addressing the doctor in the casualty department. Rane directed GMC's medical superintendent, Dr Rajesh Patil, to get orders issued to suspend the doctor, and told him to get another CMO to replace him.

Managing BP, vax, monitoring key to better diabetes care: Experts
Nagpur: From testing 10 lakh diabetic patients for high blood pressure to using real-time glucose monitoring machines, building rural diabetes care systems, and vaccinating adults, top medical experts laid out a people-centric roadmap for better diabetes care across the country. Speaking at the ongoing 12th Hello Diabetes Academia (HDA) in Nagpur, national faculty members shared actionable ideas that blend public health outreach with cutting-edge technology. Dr Anuj Maheshwari, president-elect of RSSDI and president of Asia Pacific Hypertension Society, said the RSSDI (Research Society for the Study of Diabetes in India) launched a national project from May 30 to test blood pressure in 10 lakh diabetic patients. "High BP and diabetes go hand in hand. But we need solid Indian data to understand the link between the two," Dr Maheshwari said. He also unveiled a three-year rural diabetes care project. In the first year, RSSDI teams will visit 1,000 villages across India (with populations up to 3,000), conduct house-to-house blood sugar testing, and identify diabetic patients. "Diabetes is not just an urban disease. In fact, the difference between rural and urban rates is now just 1%. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like American Investor Warren Buffett Recommends: 5 Books For Turning Your Life Around Blinkist: Warren Buffett's Reading List Undo But in rural India, the real danger is people don't even accept they have diabetes," he said. In year two, patients will receive glucometers and BP machines, along with guidance on how to manage their condition. In year three, they will be checked for diabetes-related complications. Dr Amit Gupta, senior faculty from IDF School of Diabetes, highlighted the growing use of continuous glucose monitoring (CGM) devices. "With CGM, you prick only once, and then your sugar levels are tracked in real-time for up to three weeks. It's very useful to effectively adjust insulin doses," he said. He added that CGM is particularly helpful for those whose sugar levels fluctuate widely. Though currently expensive, he believes prices will drop as usage increases. Dr Jyotirmay Paul, national president, Association of Physicians of India (API), stressed the need for adult vaccination awareness, especially among senior citizens. He shared that API prepared an adult vaccination schedule, similar to the one for children, and plans to submit it to the central govt, demanding its inclusion in public health programmes.

Panel to probe delayed birth certificates issued by Sambhajinagar GMCH & other govt hospitals
Chhatrapati Sambhajinagar: The public health department has set up a four-member committee to examine delayed birth certificates issued by the Govt Medical College and Hospital (GMCH) in Chhatrapati Sambhajinagar and other govt hospitals in the district. Similar scrutiny will be carried out for state-run health institutions in two other Marathwada districts, Jalna and Beed. The committee, headed by a Class I medical officer and including three statistical officers, must present its findings by June 13. The order dated June 5 mentions BJP politician Kirit Somaiya's allegations of widespread illegal certificate issuance in Marathwada. On the social media platform X, Somaiya claimed that GMCH, Chhatrapati Sambhajinagar, had issued 4,967 illegal birth certificates over 17 months until May. "I exposed a scam in which the GMCH, Chhatrapati Sambhajinagar, issued illegal birth certificates, totalling 4,967, from Jan 1, 2024, to May this year. The health authorities concerned issued these birth certificates without having any such right," he said. Dr Abhijeet Dhanorkar, the district health officer for Chhatrapati Sambhajinagar, explained the birth certificate applications submitted after one year require a sub-divisional magistrate (SDM) certificate. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like 5 Books Warren Buffett Wants You to Read In 2025 Blinkist: Warren Buffett's Reading List Undo "It has come to our notice that certain birth certificates were issued despite the applicant failing to furnish a certificate from the SDM. The lapse may have occurred due to a lack of knowledge among the health staffers," he told TOI. While GMCH Chhatrapati Sambhajinagar officials remained unavailable for comment, Dhanorkar confirmed full cooperation with the investigating panel regarding data provision. "If the delay in making applications for birth certificates is significant, then such cases call for further stringent scrutiny," he added. During his Marathwada visit on April 15, Somaiya alleged that numerous fraudulent birth certificates in parts of Marathwada and other Maharashtra regions were obtained by Bangladeshi nationals to legitimise their unauthorised residence in India.
