Four factors predict condition which causes strokes | Science | News

A new way of detecting a common heart condition that increases the risk of a stroke has been developed.
While not life-threatening, an irregular heartbeat – known as ‘atrial fibrillation’ – raises the chances of suffering a stroke by up to five times. Now researchers at the University of East Anglia (UEA) have identified four specific factors that can predict which patients will have atrial fibrillation.
These include older age, higher diastolic blood pressure and problems with both the coordination and function of the upper left chamber of the heart.
The UEA team has created a simple tool for doctors to use in practice to identify those at high risk. They hope it will help diagnose and treat more patients, reducing their risk of future strokes.
Lead researcher Professor Vassilios Vassiliou, of UEA’s Norwich Medical School, said: “Identifying who is at high risk and more likely to develop atrial fibrillation is very important. This is because it requires specific treatment with anticoagulants, commonly known as blood thinners, to reduce the risk of future strokes.
“Patients who have had a stroke usually undergo multiple investigations to determine the cause of the stroke, as this can influence the treatment they receive long-term. These investigations include prolonged monitoring of the heart rhythm with a small implantable device called a loop recorder, and an ultrasound of the heart, called an echocardiogram.”
The researchers collected data from 323 patients across the East of England, treated at Cambridge University Hospitals NHS Foundation Trust, who had had a stroke with no cause identified- known as Embolic Stroke of Undetermined Source. The team analysed medical records as well as data from prolonged heart rhythm monitoring. They also studied their echocardiograms.
Prof Vassiliou said: “We determined how many of these patients were found to have atrial fibrillation up to three years following their stroke, and went on to perform a thorough assessment to identify if there are specific parameters that are connected with atrial fibrillation identification.
“We identified four parameters that were linked with the development of atrial fibrillation, which were consistently present in patients that had this arrhythmia. We then developed a model that can be used to predict who will show atrial fibrillation in the next three years, and is therefore at increased risk of another stroke in the future.”
Prof Vassiliou, Honorary Consultant Cardiologist at the Norfolk and Norwich University Hospital, added: “This is a very easy tool that any doctor can use in clinical practice. And it can potentially help doctors provide more targeted and effective treatment to these patients, ultimately aiming to highlight the people at higher risk of this arrhythmia that can benefit from prolonged heart rhythm monitoring and earlier anticoagulation to prevent a future stroke.”
The study was published in the European Journal of Preventive Cardiology, and presented at the European Society of Cardiology Congress in Amsterdam.

Crude bombs exploded inside St Joseph school compound in Mohammadpur

Two crude bombs exploded inside the compound of St Joseph Higher Secondary School in the capital’s Mohammadpur area early hours of Saturday (8 November).
The school authorities filed a general diary (GD) with Mohammadpur Police Station following the incident.
Confirming the matter to The Business Standard, the station’s Officer-in-Charge (OC) Kazi Rafiqul Ahmed said, “The explosions occurred around 2am inside an open space near the school’s third gate. No casualties were reported.”
“At the time of the incident, there was no electricity in the area, making it difficult to identify anyone from CCTV footage,” the OC added.
He further said that preliminary investigations suggest that unidentified individuals might have arrived on a motorcycle, detonated the bombs, and fled the scene. “We are currently investigating the matter.”

E-money issuers must
- Maintain Tk50 crore paid-up capital
- Prepare three-year business and risk plan
- Keep settlement accounts to safeguard funds
- Continuous fraud detection mandatory
- Transparent governance with high-integrity directors
- Mandatory board audit and risk committees
- Fines of Tk50 lakh, license revocation, legal action for rule breaches
- Stakeholders invited to submit feedback before final approval
- Existing operators must reapply within six months of enforcement
The Bangladesh Bank has unveiled draft rules allowing non-bank local and foreign companies to obtain licences to operate as Payment Service Providers (PSPs) or Mobile Financial Service (MFS) providers.
The central bank has published a draft of the “Regulations for E-Money Issuers in Bangladesh” on its website for public consultation, breaking away from the long-standing bank-led model that has dominated mobile and online financial services.
Under the new structure, both banks and independent digital finance companies will be authorised to issue e-money upon approval from the central bank.
Existing MFS and PSP operators – whether bank-led or otherwise – must apply for new licences within six months of the regulations taking effect to comply with the updated framework.
At present, e-money in Bangladesh is issued by mobile financial service providers such as bKash, Rocket, and Nagad, alongside payment service providers like TallyPay, Pathao Pay, and Sheba Pay. These institutions generate e-money through digital transactions and payment services.
The Bangladesh Bank has introduced the draft regulations to bring such activities under a formal legal and supervisory structure, ensuring institutional stability, financial security, and consumer protection.

According to the draft, the new rules aim to “promote financial inclusion, ensure the safety and reliability of e-money, and foster a competitive and innovation-driven payments environment”.
A senior Bangladesh Bank official, speaking on condition of anonymity, described the draft as “a milestone reform which will open up the digital finance space beyond traditional banks”.
He said the goal is to encourage competition, innovation, and interoperability. “We want a safe, inclusive, and technology-neutral framework where both banks and fintechs can expand financial access.”
Industry leaders have welcomed the move. “Allowing non-bank EMIs could significantly accelerate innovation and partnerships in mobile and online payments,” said a leading fintech executive.
Draft rules
The framework introduces two categories of e-money issuers: authorised EMIs, comprising regulated institutions such as banks and finance companies, and dedicated EMIs (DEMIs), non-bank entities exclusively engaged in e-money and related payment activities.
Applicants, especially DEMIs, must maintain a minimum Tk50 crore paid-up capital, submit a three-year business and risk plan, ensure fit and proper governance, and establish Trust and Settlement Accounts to safeguard customer funds.
E-money issuers must also implement a robust risk management framework, maintain tested technology systems with sound internal controls, employ multi-factor authentication for high-value transactions, and ensure continuous fraud detection and cyber resilience against evolving threats.
They must also establish effective and transparent governance, featuring directors of high integrity and strict segregation of duties, while requiring mandatory board audit and risk committees to ensure robust internal controls and continuous regulatory oversight.
Violations of the rules could result in fines of at least Tk50 lakh, license revocation, or civil and criminal proceedings.
Stakeholders have been invited to submit feedback before the final regulations are issued. Once adopted, the new framework is expected to reshape Bangladesh’s digital finance industry, aligning it more closely with international practices seen in China, India, and Malaysia.
Bangladesh Bank will exercise oversight and supervisory powers over e-money issuers under the authority granted by the Bangladesh Bank Order, 1972 and the Payment and Settlement Systems Act, 2024.
