iRhythm Technologies Announces Results of GUARD-AF Trial
- GUARD-AF trial results presented at European Society of Cardiology (ESC) Congress 2024
- Leveraging iRhythm’s Zio ® patch-based long-term continuous monitoring (LTCM), GUARD-AF is the largest randomized trial in a primary care setting to evaluate the impact of screening for undiagnosed atrial fibrillation (AF)
- Screening with iRhythm’s Zio ® XT1 LTCM led to increase in new diagnosis of AF (5.0% vs 3.3%) over an average follow-up of 15 months.
- No difference in stroke hospitalization vs usual care in the context of reduced statistical power due to truncated enrollment and follow-up.
SAN FRANCISCO, Sept. 01, 2024 (GLOBE NEWSWIRE) — iRhythm Technologies, Inc. (NASDAQ:IRTC), a leading digital health care company focused on creating trusted solutions that detect, predict, and prevent disease, today announced the presentation and publication of the GUARD-AF (ReducinG stroke by screening for UndiAgnosed atRial fibrillation in elderly inDividuals) randomized clinical trial at the European Society of Cardiology (ESC) Congress 2024. The trial was sponsored by Bristol-Myers Squibb-Pfizer Alliance and iRhythm provided the Zio XT patch ECG long-term continuous monitoring (LTCM) monitor used in the interventional (screening) arm of the study.
GUARD-AF was a prospective, parallel-group, randomized controlled trial designed to test whether screening for AF in people aged ‰¥70 years using an on-label Zio ® XT 14-day single-lead LTCM could identify patients with undiagnosed AF and reduce stroke. Participants were randomized 1:1 to screening with Zio XT LTCM or usual care. The primary efficacy and safety outcomes were hospitalization due to all-cause stroke and bleeding, respectively.
During a median follow-up of 15 months in 11,905 enrolled patients from 149 primary care sites in the US (5,952 assigned to screening), the study found that Zio XT LTCM led to an increase in new diagnosis of AF vs usual care (5.0 vs 3.3%) through the end of follow-up. There was no significant difference between groups in incidence of the primary endpoint of stroke hospitalization, although event rates were low and the trial was stopped before achieving enrollment of the planned total of 52,000 patients during the COVID-19 pandemic2, thereby reducing statistical power. Findings were presented by Dr. Renato Lopes, Professor of Medicine at the Duke Clinical Research Institute and Duke University, at the ESC Congress on September 1 and simultaneously published in two tandem manuscripts in the Journal of the America College of Cardiology (JACC)3 and the JACC: Clinical Electrophysiology.4
Owing in part to the low event rate and truncated enrollment, the study found no reduction in the rate of stroke, said Dr. Lopes. However, there are some important lessons here. Our study confirms that AFib is common in older patients and can be identified with cardiac monitoring in primary care ” upstream of cardiology care, which many patients will not have access to. Most participants with AFib also had short, infrequent episodes that would be missed with a pulse check, single ECG, shorter duration of monitoring. Identification of these short episodes could be a useful prompt for physicians to more aggressively treat heart disease risk factors and may reduce the downstream risk of heart failure, which will be evaluated in future trials.
The study had several notable implications:
- Screening with Zio XT LTCM led to an increase in diagnosis of AF over the maximum 2.5 years of follow up vs usual care (5.0% vs 3.3%), an increase in initiation of oral anticoagulation that is used for prevention of stroke in AF (4.2% vs 2.8%), and no increase in the rate of hospitalization for bleeding.3
- Primary care-initiated home-based monitoring in an older population is feasible. GUARD-AF is the largest randomized trial to evaluate the impact of AF screening with a patch-based ECG monitor on care delivery in a primary care setting; more than half of participants enrolled were women.3
- Virtual, home-based diagnostics are feasible. In GUARD-AF, 20% of participants were enrolled virtually and received the Zio XT LTCM device by mail for self-application. Wear time and analyzable time were similar and high in self-applied and clinic-applied groups3, confirming prior studies and clinical experience with Zio LTCM service.5
- In the 252 participants with AF detected on 14-day LTCM, most (88%) had low-burden paroxysmal AF. Of those with detected AF, most had AF 3, suggesting that many patients with diagnosed AF may miss detection with 12-lead ECG (10 seconds), smartwatch ECG (30 seconds), or ambulatory monitoring of shorter duration such as 48 hours. Only 32 of 252 had AF at the start of the ECG recording.
Additionally, this research underscores how large pragmatic trials powered by the Zio LTCM service are feasible at scale. iRhythm’s clinical research services have supported over 100 prospective studies at nearly 500 sites in over 40,000 participants.
These findings support the totality of evidence that undiagnosed AFib is common and can be found with Zio’s 14-day long-term monitoring ” even when it is not likely to be found with point-of-care ECGs or short-term monitors due to the short, infrequent episodes in the early stages of atrial fibrillation, said Mintu Turakhia MD, iRhythm’s Chief Medical and Scientific Officer and EVP, Product Innovation. iRhythm’s undiagnosed arrhythmia pilot programs leverage many features seen in GUARD-AF, such as virtual enrollment and self-applied patches at home. These programs, as well as ongoing clinical trials, such as AMALFI6, and those in development will have longer follow-up or assess a wider range of outcomes, including heart failure, which occurs in one-third of patients with AFib, along with cardiovascular hospitalization, health care utilization, and costs.
Also at ESC, Evangelos Hytopoulos, PhD, iRhythm’s Sr. Director of Data Science, presented separate work performed in collaboration with Scripps Research, New insights from the ECG: screening and prediction7, that used machine learning on ECG signal of 14-days of patch-based monitoring without AF to successfully predict episodes of AF in the subsequent year. The research presented is part of a scientific study only and is not part of any commercial product offering in any market.

Quipt Home Medical (TASE:) Corp. (QIPT) stock has reached a new 52-week low, trading at $2.55. This latest price point marks a significant downturn for the company, which has experienced a 46.87% decline over the past year. Investors are closely monitoring the home medical equipment provider as it navigates through a challenging period marked by this notable decrease in stock value. The 52-week low serves as a critical indicator for the market, reflecting investor sentiment and potential shifts in the company’s financial health and operational performance.
In other recent news, Quipt Home Medical Corp has been making notable strides despite facing several challenges. The company’s third fiscal quarter report revealed a steady increase in revenue, reaching $64 million, a 6.1% rise from the previous year. The customer base also expanded by 9%, serving 153,223 unique patients, and adjusted EBITDA grew by 2.7% to $14.2 million.
Benchmark revised its stock price target for Quipt Home Medical, reducing it to $7 from the previous $9, but maintained a Buy rating for the stock. This adjustment was influenced by several factors including the expiration of Medicare’s 75/25 rate relief, a diminished Managed Care contract, and the repercussions of the Change Healthcare (NASDAQ:) cyberattack. However, the firm predicts that Quipt could achieve an 8%-10% organic growth rate by the second quarter of fiscal year 2025.
In the face of these challenges, Quipt Home Medical has reported a 9% increase in resupply revenue for sleep therapy and supplies, which accounts for half of the company’s revenues.

These are the recent developments that investors should keep an eye on.

Investors looking for a deeper analysis can find 7 additional InvestingPro Tips for QIPT, offering a more comprehensive view of the company’s financial situation and market position.

Muslims who voted for Trump upset by his pro-Israel cabinet picks
By Andrea Shalal
WASHINGTON (Reuters) – U.S. Muslim leaders who supported Republican Donald Trump to protest against the Biden administration’s support for Israel’s war on Gaza and attacks on Lebanon have been deeply disappointed by his Cabinet picks, they tell Reuters.
“Trump won because of us and we’re not happy with his Secretary of State pick and others,” said Rabiul Chowdhury, a Philadelphia investor who chaired the Abandon Harris campaign in Pennsylvania and co-founded Muslims for Trump. Muslim support for Trump helped him win Michigan and may have factored into other swing state wins, strategists believe.
Trump picked Republican senator Marco Rubio, a staunch supporter of Israel for Secretary of State. Rubio said earlier this year he would not call for a ceasefire in Gaza, and that he believed Israel should destroy “every element” of Hamas. “These people are vicious animals,” he added.
Trump also nominated Mike Huckabee, a former Arkansas governor and staunch pro-Israel conservative who backs Israeli occupation of the West Bank and has called a two state solution in Palestine “unworkable”, as the next ambassador to Israel.
He has picked Republican Representative Elise Stefanik, who called the UN a “cesspool of antisemitism” for its condemnation of deaths in Gaza, to serve as U.S. ambassador to the United Nations.
Rexhinaldo Nazarko, executive director of the American Muslim Engagement and Empowerment Network (AMEEN), said Muslim voters had hoped Trump would choose Cabinet officials who work toward peace, and there was no sign of that.
“We are very disappointed,” he said. “It seems like this administration has been packed entirely with neoconservatives and extremely pro-Israel, pro-war people, which is a failure on the on the side of President Trump, to the pro-peace and anti-war movement.”
Nazarko said the community would continue pressing to make its voices heard after rallying votes to help Trump win. “At least we’re on the map.”
Hassan Abdel Salam, a former professor at the University of Minnesota, Twin Cities and co-founder of the Abandon Harris campaign, which endorsed Green Party candidate Jill Stein, said Trump’s staffing plans were not surprising, but had proven even more extreme that he had feared.
“It’s like he’s going on Zionist overdrive,” he said. “We were always extremely skeptical…Obviously we’re still waiting to see where the administration will go, but it does look like our community has been played.”
The Trump campaign did not immediately respond to an email seeking comment.
Several Muslim and Arab supporters of Trump said they hoped Richard Grenell, Trump’s former acting director of national intelligence, would play a key role after he led months of outreach to Muslim and Arab American communities, and was even introduced as a potential next secretary of state at events.
Another key Trump ally, Massad Boulos, the Lebanese father-in-law of Trump’s daughter Tiffany, met repeatedly with Arab American and Muslim leaders.
Both promised Arab American and Muslim voters that Trump was a candidate for peace who would act swiftly to end the wars in the Middle East and beyond. Neither was immediately reachable.
Trump made several visits to cities with large Arab American and Muslim populations, include a stop in Dearborn, a majority Arab city, where he said he loved Muslims, and Pittsburgh, where he called Muslims for Trump “a beautiful movement. They want peace. They want stability.”
Rola Makki, the Lebanese American, Muslim vice chair for outreach of the Michigan Republican Party, shrugged off the criticism.
“I don’t think everyone’s going to be happy with every appointment Trump makes, but the outcome is what matters,” she said. “I do know that Trump wants peace, and what people need to realize is that there’s 50,000 dead Palestinians and 3,000 dead Lebanese, and that’s happened during the current administration.”
