AFib Health Updates

New blood thinners might work better for AFib on dialysis

This research looked at two blood thinners — Eliquis (apixaban) and Xarelto (rivaroxaban) — compared to an older blood thinner called warfarin, in people who have atrial fibrillation (an irregular heartbeat that raises stroke risk) and are on dialysis due to serious kidney disease. The study found that Eliquis and Xarelto were linked to lower rates of dangerous bleeding, stroke, and death compared to warfarin in this group, which is a meaningful safety and effectiveness update for a population that has historically been very difficult to treat. This adds to a growing picture suggesting these newer blood thinners may be a safer option than warfarin for people in this specific situation, though your doctor would weigh all the details before making any decision.

Wearables may spot heart problems you don't need treated

Researchers found something surprising: smartwatches and wearable heart monitors were very good at spotting atrial fibrillation — an irregular heartbeat that can raise the risk of serious heart problems like heart attacks or strokes — but finding more cases didn't actually seem to lead to better health outcomes for people screened. In fact, continuous monitoring nearly tripled the number of diagnoses and doubled the use of blood-thinning medications, yet the extra treatment didn't clearly prevent harm, raising the question of whether some of those diagnoses may not have needed treatment at all — a concept called 'overdiagnosis,' meaning the condition was detected but may never have caused problems. Someday this research might help doctors figure out who truly benefits from wearable heart screening, rather than putting more people through treatment they may not need. This is early research and hasn't yet changed treatment guidelines.

Heart Procedure May Work as Well as Blood Thinners

Researchers found that a small procedure called left atrial appendage closure — where a tiny device is placed to seal off a small pouch in the heart that's often the source of stroke-causing clots — performed similarly to blood-thinning medication when it came to preventing serious heart problems like heart attacks or strokes in people with atrial fibrillation (an irregular heartbeat). However, people who had the device also experienced fewer bleeding episodes unrelated to the procedure itself, which could matter for those who struggle with bleeding risks on blood thinners. This is early research and hasn't yet changed treatment guidelines.

Simpler heart device may work as well as standard pacemaker

A study found that a simpler two-lead heart device performed just as well as the traditional three-lead version in people with heart failure who needed a special pacemaker called cardiac resynchronization therapy — essentially a device that helps the heart's chambers beat in better sync. Researchers tracked over 600 patients for a year and found similar rates of death, hospital visits, and device problems between the two groups, suggesting the simpler device (which has one fewer wire implanted in the heart) may be a viable option. This is early research and hasn't yet changed treatment guidelines.

Heart procedure combo may lower stroke risk

A study found that for people with atrial fibrillation (an irregular heartbeat that raises stroke risk) who had a procedure called catheter ablation — where doctors use heat or cold energy to correct the heart's electrical signals — a small implanted device that closes off a pouch in the heart called the left atrial appendage may protect against stroke just as well as blood-thinning medication, while causing fewer bleeding problems. Interestingly, this benefit showed up even in patients who were already considered low-risk for bleeding, not just those most prone to it. This is early research and hasn't yet changed treatment guidelines.

New heart rhythm treatment may work better for some AF patie

Researchers found that for people with a type of irregular heartbeat called atrial fibrillation (AF) — where the heart beats chaotically instead of in a steady rhythm — a specific ablation technique may work better for some patients than others. Ablation is a procedure that uses heat or cold energy to destroy small areas of heart tissue causing the irregular signals; this study looked at whether also targeting 'low-voltage areas' (patches of damaged heart tissue in the upper left chamber) helped reduce AF coming back, and found it only made a meaningful difference in patients who had the largest patches of that damaged tissue. This is early research and hasn't yet changed treatment guidelines.

Plant-based eating may cut heart disease risk

This research combined data from 23 studies and found that people with type 2 diabetes — and adults generally — who closely followed the Planetary Health Diet (an eating pattern built around vegetables, fruits, whole grains, legumes like beans and lentils, and nuts, with little red meat or processed food) had about 17–18% lower chances of death or serious heart problems like heart attacks or strokes. The benefit wasn't all-or-nothing: meaningful risk reductions appeared once people reached a moderate-to-high level of the diet, suggesting that gradually eating more plants and less processed meat — even starting with one meal today — may matter. The researchers note these studies show a strong link but can't yet prove the diet directly causes these better outcomes, so this is promising but not the final word.

Blood thinners after stroke: timing may not matter much

A study found that in people who had a stroke and also had atrial fibrillation (an irregular heartbeat that raises the risk of stroke), starting blood-thinning medication within 4 days versus waiting 7–14 days did not clearly change outcomes — including the chances of having another stroke — regardless of whether the irregular heartbeat was diagnosed before or after the stroke. Researchers looked at over 3,600 patients to see if the timing of the diagnosis or the type of irregular heartbeat made a difference in when to start the medication, and no strong difference was found between the two groups.

Blood Thinners May Not Be Needed After Heart Rhythm Fix

A study looking at data from over 267,000 patients found that people who stopped taking blood thinners after a procedure called AF ablation — where doctors use heat or cold energy to correct an irregular heartbeat — had significantly fewer serious bleeding episodes, without a clear increase in their risk of stroke or blood clots. This is notable because current medical guidelines tell doctors to keep patients on blood thinners based on a stroke-risk score, not on whether the ablation procedure worked. People with atrial fibrillation who have had or are considering an ablation may want to ask their doctor what this newer research could mean for their own blood thinner plan going forward.

Low-dose blood thinner may work better after heart procedure

A study found that people with atrial fibrillation — an irregular heartbeat that raises the risk of serious heart problems like heart attacks or strokes — who had a procedure to close off a small pouch in the heart (called left atrial appendage occlusion) did better when they took a low dose of a blood-thinning medication for the first three months after the procedure, compared to those who took two antiplatelet drugs (medicines that help prevent clots by stopping platelets from sticking together). Researchers found that the low-dose blood thinner group had fewer clots forming on the device and less bleeding over the course of a year, with most of the difference happening in those first three months. People with atrial fibrillation who have had or are considering this procedure may want to ask their doctor which blood-thinning approach is planned right after the procedure and why.

New blood thinner may be safer for dialysis patients

Researchers found that for people with atrial fibrillation (an irregular heartbeat) who are also on dialysis due to severe kidney failure, one type of blood thinner called DOACs appeared safer than an older type called warfarin (or similar drugs), with a lower risk of serious bleeding and potentially a lower risk of death. This matters because people on dialysis are in a tricky situation — they need blood thinners to prevent strokes, but they also have a higher risk of bleeding, so finding the safer option is really important. This is early research and hasn't yet changed treatment guidelines.

Heart procedure may work as well as blood thinners

Researchers found that a small procedure called left atrial appendage occlusion (LAAO) — where a tiny device is placed to seal off a pouch in the heart that often causes clots — worked about as well as newer blood thinners and better than warfarin (an older blood thinner) at reducing serious heart problems like heart attacks or strokes in people with atrial fibrillation, which is an irregular heartbeat that raises stroke risk. Warfarin was also linked to higher rates of death compared to the LAAO procedure and the newer blood thinners. This is early research and hasn't yet changed treatment guidelines.

When AFib Returns After Heart Procedure

Researchers found that in people with paroxysmal atrial fibrillation — a condition where the heart beats irregularly in unpredictable episodes — most cases of the irregular heartbeat returning after a catheter ablation procedure (a treatment that uses heat or cold energy to correct the heart's electrical signals) happen within the first 6 to 9 months, with about 85% of all recurrences showing up by month 9. This suggests that closely watching patients during that earlier window may be especially important, and that results seen at 6 months may be a reliable early indicator of how well the procedure worked at the full 12-month mark. This is early research and hasn't yet changed treatment guidelines.

Blood thinner may be safer than aspirin after certain stroke

A study found that apixaban (brand name Eliquis), a blood-thinning medication, caused fewer bleeding episodes inside the brain compared to aspirin in people who had experienced a stroke of unknown cause along with signs of heart irregularities. This is a safety-related finding, suggesting that when it comes to brain bleeding risk, Eliquis may actually be the safer choice over aspirin in this group — which might surprise some people who think of aspirin as the gentler option. Researchers followed over 1,000 patients for nearly two years to reach these findings.

New procedure may help beyond just blood pressure

Researchers found that a procedure called renal denervation — where nerves near the kidneys are disrupted to help lower high blood pressure — may also have benefits beyond just blood pressure control. The study found it was linked to improvements in heart rhythm problems, sleep apnea (a condition where breathing repeatedly stops during sleep), fasting blood sugar levels, and how well the heart's lower chambers relax and fill with blood. This is early research and hasn't yet changed treatment guidelines.

Women's heart rhythm patterns may respond better to targeted

Researchers found that women with atrial fibrillation — an irregular heartbeat where the heart's upper chambers quiver instead of pumping normally — tend to fall into specific heart rhythm patterns that appear to respond better to a particular type of ablation procedure, which uses heat or cold energy to scar small areas of heart tissue and restore a normal rhythm. This suggests that mapping the electrical flow patterns in the heart before surgery may be especially useful for guiding treatment decisions in women. This is early research and hasn't yet changed treatment guidelines.

Blood thinner alone may work as well as blood thinner plus a

A study found that for people with stable coronary artery disease (a condition where the heart's blood vessels are narrowed) who also need long-term blood thinners, taking a blood thinner alone worked just as well at preventing serious heart problems like heart attacks or strokes as taking a blood thinner plus an antiplatelet drug like aspirin — and it caused notably less bleeding. Researchers also found that the blood-thinner-only approach was linked to fewer deaths from heart-related causes. This could be a helpful conversation starter for patients in this situation to have with their doctor about which combination of medications is right for them.

Blood thinner may raise bleeding risk in older patients

A study found that a blood-thinning medication called edoxaban (brand name Savaysa), used to help prevent strokes in people with atrial fibrillation — an irregular heartbeat — carries a higher risk of serious bleeding in very elderly patients who have more of the drug building up in their system. Researchers found that older age, lower body weight, and reduced kidney function all contributed to higher drug levels, which in turn were linked to more bleeding events. This is a safety-related finding, not a new treatment option.

Plant-Based Diet May Help Your Heart Health

A study found that eating more plant-based foods — like vegetables, beans, nuts, and whole grains — while cutting back on red meat and processed meat may help improve heart health in people with type 2 diabetes. Researchers found this shift in eating habits was linked to a lower chance of serious heart problems like heart attacks or strokes. The findings suggest that what people put on their plate regularly can make a meaningful difference for their heart over time.

5 Cannabis Risks Older Adults Should Know About

Be aware that cannabis use carries specific risks for adults over 65, including a higher chance of serious heart problems like heart attacks or strokes, falls, and memory issues — and today's cannabis is much stronger than it used to be. It can also interact dangerously with other medications, so people in this age group taking any prescriptions should be especially cautious. Anyone who notices dizziness, confusion, a fast or irregular heartbeat, or unexpected changes in how their medications seem to work should reach out to their doctor.

Blood Thinners After Stroke: One Drug vs. Two?

This research looked at blood-thinning medications — specifically comparing taking a blood thinner (called an oral anticoagulant, a drug that helps prevent clots) alone versus combining it with an antiplatelet drug (like aspirin, which also helps prevent clots) in people who have atrial fibrillation (an irregular heartbeat that raises stroke risk) and hardening of the arteries, and who have already had a stroke. The study, which pooled results from 10 smaller studies involving over 14,000 patients, found that using the blood thinner on its own appeared to rank better overall for avoiding a mix of serious outcomes — including another stroke — compared to using both drugs together, though the differences were not statistically definitive (meaning they could have been due to chance). This appears to be a new piece of evidence potentially pointing toward a simpler treatment approach, rather than a safety warning or official guideline change.

Ultra-Processed Foods May Raise Heart Disease Risk

Researchers found that eating a lot of ultra-processed foods — things like packaged snacks, fast food, sugary drinks, and ready-made meals that are made in factories with added sugars, unhealthy fats, salt, and artificial ingredients — is consistently linked to higher risks of serious heart problems like heart attacks or strokes, obesity, and death in people with type 2 diabetes and in the general population. These foods tend to be low in fiber and nutrients, which may make blood sugar control harder for people with diabetes. The researchers note that scientists are still working to fully understand exactly how and why these foods affect heart health.

New guidance on heart rhythm meds after stent placement

A study published in the New England Journal of Medicine looked at treatment options for people who have atrial fibrillation — an irregular heartbeat — and have also had a drug-eluting stent placed, which is a small mesh tube inserted into a blocked artery to keep it open. Researchers examined how to manage blood-thinning medications for these patients, since both conditions typically require blood thinners but combining them can raise the risk of bleeding. This appears to be new research exploring treatment options for this tricky combination, rather than a safety warning or an established guideline recommendation.

New Heart Procedure May Better Stop Irregular Heartbeats

Researchers found that a newer heart procedure called pulsed field ablation — which uses targeted electrical energy instead of heat or cold to correct an irregular heartbeat called atrial fibrillation — showed fewer cases of the irregular rhythm coming back compared to older ablation methods, and the procedures took less time to complete. This could matter someday for people with a persistent form of atrial fibrillation (meaning the irregular heartbeat doesn't stop on its own), since shorter procedures and better results would be meaningful improvements. This is early research and hasn't yet changed treatment guidelines.

Closing Heart Pouch May Lower Stroke Risk

Researchers looked at a surgical procedure that closes off a small pouch in the heart — called the left atrial appendage — to help reduce stroke risk in people with atrial fibrillation (an irregular heartbeat that can cause dangerous blood clots). They found that across many studies, the procedure appeared to work about 93% of the time overall, but hospitals are using 17 different definitions of 'success,' which makes it hard to know if results are truly being measured the same way everywhere. Someday, agreeing on a single clear standard could help doctors better understand whether the procedure is truly protecting people from strokes. This is early research and hasn't yet changed treatment guidelines.

Women may face higher risks after heart rhythm procedure

Researchers looked at data from over 100,000 people who had a procedure called catheter ablation — where doctors use heat or cold energy to correct an irregular heartbeat called atrial fibrillation — and asked whether women and men had different outcomes. They found that women appeared to have a higher chance of serious complications from the procedure, even though their chances of the irregular heartbeat coming back were about the same as men's. If confirmed in future research, this could someday help doctors have more personalized conversations with female patients about the risks before choosing this treatment. This is early research and hasn't yet changed treatment guidelines.

High Coffee Intake May Raise Heart Attack Risk

A large analysis combining data from over 2.8 million people found that drinking higher amounts of coffee was linked to a 48% greater chance of having a heart attack compared to drinking very little coffee — though it did not appear to raise the overall risk of other heart conditions like heart failure. For people with type 2 diabetes, who already face a higher risk of serious heart problems like heart attacks or strokes, this is worth noting, though the research doesn't tell us exactly how many cups cross the line. Your doctor can help weigh whether current coffee habits make sense alongside any other heart or blood sugar concerns.

Heart scan findings may predict AFib relapse

Researchers looked at whether certain damaged or scarred areas of the heart's upper left chamber — detected during a procedure called pulmonary vein isolation, a common treatment for atrial fibrillation (an irregular heartbeat) — could predict which patients were more likely to have their irregular heartbeat come back afterward. Across 15 studies involving nearly 4,000 patients, they found that people who had these low-activity areas in their heart were roughly twice as likely to see their atrial fibrillation return after treatment, which is interesting because it could someday help doctors identify who needs closer monitoring or a different approach before they even start treatment. This is early research and hasn't yet changed treatment guidelines.

Do routine health checks actually prevent heart disease?

Researchers looked at whether routine 'health check' programmes — where adults get screened for things like high blood pressure or risk of serious heart problems like heart attacks or strokes — actually help people stay healthier in countries where healthcare is free at the point of use. The idea is that catching these risks early, including in people with type 2 diabetes, might allow doctors to step in sooner and potentially prevent serious illness down the line. This is early research and hasn't yet changed treatment guidelines.
