The Integrative Cardiologist · By Sameer Azhak, MD, FACC
Every November, the American Heart Association (AHA) holds its biggest meeting of the year. Doctors and scientists from around the world gather to share brand-new research. This year, in Chicago, more than 20 major “late-breaking” studies were presented for the first time.¹
Some of these studies brought good news. Some showed us how to use treatments we already have a little better. And a few showed that a promising new drug did not help as much as everyone hoped.
You don’t need to follow every study. But some of these findings may come up at your next doctor’s visit, so here is what I think matters most. I’ll start with the things that lead to heart disease, like blood pressure, cholesterol, and weight. Then I’ll move on to the conditions themselves: heart attack, stroke, heart failure, and heart rhythm problems.
One idea to keep in mind
Almost every study this year pointed to the same lesson:
A medicine that improves your blood test is not always a medicine that protects your heart.
A good number on a lab report is encouraging. But what really matters is whether a treatment helps people live longer and avoid heart attacks, strokes, and trips to the hospital. Keep that idea in mind as you read.
To make the results easier to picture, I’ll describe them as “out of 100 people” whenever I can.
Part 1: The things that lead to heart disease
Healthy habits: still the foundation
Only one of this year’s major studies tested a lifestyle program: yoga-based rehab for heart failure, which you’ll read about below. None tested a diet. That doesn’t mean habits don’t matter. It’s actually a reminder of how much they do.
As you’ll see below, several new drugs made blood tests look much better but did not prevent heart attacks or strokes any better than a placebo. Meanwhile, the everyday basics are still the best-proven protection we have. The AHA sums them up as “Life’s Essential 8”:²
Eat mostly whole foods: vegetables, fruits, beans, whole grains, nuts, seeds, and lean protein such as fish
Move your body most days, aiming for about 150 minutes of moderate activity a week
Sleep 7 to 9 hours a night
Don’t smoke or vape
Keep your weight, cholesterol, blood sugar, and blood pressure in a healthy range
Blood pressure: the right goal depends on your history
Blood pressure is written as two numbers, like 130/80. The top number shows how hard your blood pushes on your artery walls with each heartbeat. Three studies looked at how low that top number should go.
If you’ve had a stroke: About 4,400 stroke survivors were split into two groups. One group aimed for a top number below 120. The other aimed for below 140. Over about four years, around 11 out of 100 people in the lower group had another stroke, heart attack, or other serious heart problem. In the standard group, it was around 14 out of 100.³ The lower goal did come with a trade-off: kidney problems were more common, so careful check-ups and blood tests were important.⁴
If you have diabetes: A larger study of about 9,500 people with type 2 diabetes tested the same two goals. This time, the lower goal did not make a clear difference in heart problems, and kidney problems were again more common.⁵
An inexpensive pill after stroke: In a smaller study, adding an old, low-cost “water pill” called spironolactone helped stroke survivors bring their blood pressure down about 8 points in three months.⁶ Some people felt lightheaded or had high potassium levels, so blood tests matter here too.⁷ This study only measured blood pressure. It didn’t test whether fewer strokes followed.
What this means for you: There’s no single “perfect” blood pressure for everyone. If you’ve had a stroke or a “mini-stroke,” ask your doctor whether your goal should be lower. If you have diabetes, the right goal depends more on your overall health.
Cholesterol: lower “bad” cholesterol still helps, and stopping has a cost
LDL is often called “bad” cholesterol because it builds up in the walls of your arteries. Statins are the most common medicines used to lower it.
Stopping statins after age 70: Nearly 1,900 adults aged 70 or older, all living with at least two long-term health conditions, were taking a statin to prevent a first heart attack or stroke. Half stopped their statin and half kept taking it. Over about two years, around 13 out of 100 people who stopped had a heart attack, stroke, or died. Among those who kept taking it, it was around 9 out of 100.⁸ The study was designed to test whether stopping was “not meaningfully worse,” and by the researchers’ preset yardstick it passed. Still, the researchers estimated about one extra heart attack, stroke, or death for every 40 people who stopped over two years.⁹ Stopping also didn’t make people feel better. Their aches, falls, and quality of life were about the same.⁹
One pill or two to start: In people who already had heart disease, starting with two cholesterol medicines (a statin plus one called ezetimibe) lowered LDL further than starting with a statin alone. But once doctors adjusted the doses over time, both groups had about the same number of heart problems.¹⁰ An earlier report from the same study found that getting LDL very low (below 55) protected people better than a more modest goal (below 70).¹¹
Lp(a), the cholesterol you inherit: Lp(a), pronounced “L-P-little-a,” is a type of cholesterol particle set mostly by your genes. A new injection lowered Lp(a) by nearly 80% in people with heart disease. But the same number of people had heart attacks and strokes whether they got the drug or a placebo (a dummy injection): about 12 out of 100 in each group.¹²
Triglycerides, another blood fat: Two experimental treatments, a monthly shot and a one-time gene-editing treatment, lowered triglycerides a lot.¹³˒¹⁴ But it’s too early to know whether they prevent heart attacks.
What this means for you:
Turning 70 or 80 is not, by itself, a reason to stop a statin. Talk it through with your doctor first.
Getting LDL lower is still worth it, and there’s more than one good way to get there.
The Lp(a) result applies only to that one drug. It doesn’t mean Lp(a) is harmless, and it doesn’t mean lowering LDL cholesterol doesn’t work.
Inflammation: a better lab test isn’t the same as better health
Inflammation is the body’s response to injury, and it plays a role in clogged arteries. A blood test called CRP can measure it.
In one large study, people with heart disease and kidney disease received a new anti-inflammatory injection or a placebo. Compared with the placebo, the drug lowered CRP by about 64%. But heart attacks, strokes, and deaths happened at almost exactly the same rate in both groups: about 18 out of 100.¹⁵ People taking the drug also had more serious infections and blood clots.¹⁶
What this means for you: This is the clearest example of the lesson above. Making a blood test look better doesn’t guarantee your heart is better protected.
Weight and sleep apnea: new medicines, wider reach
A new weight-loss shot: In about 5,500 adults with obesity and a high risk of heart disease, a new weekly injection called survodutide helped people lose up to about 14% of their body weight and nearly 5 inches around the waist. It did not raise the risk of heart problems.¹⁷ This study was designed to show the drug is safe for the heart. It doesn’t yet prove the drug protects the heart.¹⁸
A daily pill for sleep apnea: Sleep apnea means your breathing stops and starts again and again while you sleep. In about 700 adults with sleep apnea and extra weight who did not have diabetes, a daily pill called orforglipron, from the same family as Ozempic and similar medicines, cut breathing pauses by about 18 per hour of sleep, compared with about 5 per hour with a placebo. People also lost about 10% of their weight, and their blood pressure improved.¹⁹ Upset stomach, nausea, and other stomach or bowel side effects were common.²⁰
What this means for you: Untreated sleep apnea strains your heart and raises your blood pressure. If you snore loudly, wake up gasping, or feel sleepy during the day, ask your doctor about a sleep test. If you already use a CPAP machine, don’t stop using it because of this news.
Part 2: Heart and blood vessel disease
Heart attack and chest pain
When someone has chest pain, doctors often order a stress test, which checks how your heart handles exercise. One new study compared that with a special CT scan that shows the plaque inside the heart’s arteries, read with the help of artificial intelligence (AI).
In about 500 people with chest pain, the AI-read scan gave doctors more confidence about what was causing the pain. Many more people ended up on cholesterol medicine: 75%, compared with 47% in the stress-test group.²¹ These early results come from the company that makes the technology, and they haven’t yet been reviewed by outside experts. We also don’t know yet whether this approach prevents heart attacks.
What this means for you: Seeing the plaque directly may change how chest pain is checked and treated. But it’s too early to say it’s better for your long-term health.
Stroke
Besides the blood pressure results above, one large study looked at preventing a second stroke. About 12,000 people who had recently had a stroke caused by a clot, or a “mini-stroke,” took a new blood thinner called asundexian along with their usual aspirin-type medicine.
Around 6 out of 100 people taking the new medicine had another stroke caused by a clot. Among those taking a placebo, it was around 8 out of 100. Serious bleeding was about the same in both groups.²² On November 9, 2026, the FDA approved asundexian (brand name Sunharbo) for this use, taken along with aspirin-type medicine.²³
What this means for you: If you’ve had a stroke or a “mini-stroke,” there are now two new things to ask your doctor about: a lower blood pressure goal, and a newly approved option for preventing clots.
Heart failure
Heart failure doesn’t mean the heart has stopped. It means the heart isn’t pumping as strongly as it should, which can cause tiredness, shortness of breath, and swelling.
Yoga as heart rehab: Nearly 3,500 people with heart failure joined either a yoga-based rehab program or regular care. The yoga program included gentle poses, breathing exercises, meditation, and health coaching. People in the yoga group reported a better quality of life and could walk farther, about 25 meters more in a six-minute walking test. The combined rate of deaths, hospital stays, and strokes was a little lower (about 21 out of 100, compared with about 23), but not by enough to be sure it wasn’t chance.²⁴ People who practiced yoga most days of the week seemed to do best, though this kind of after-the-fact comparison can’t prove the yoga was the reason.²⁵
New tech to spot trouble early:
Voice: A smartphone app that listens to your voice each day picked up about 2 out of 3 heart failure flare-ups, about three weeks before people needed care.²⁶
Smartwatch: A smartwatch heart reading checked by AI could spot a weak heart, but two different watch brands sometimes gave different answers.²⁷
Heart ultrasound: AI helped doctors read heart ultrasounds (echocardiograms) in about half the time. Cardiologists needed to make major corrections to the AI’s draft reports about as often as to drafts prepared by people.²⁸
What this means for you: Yoga and other mind-body programs can help people with heart failure feel and function better, and that matters. The new technology is exciting, but none of it has yet been shown to keep people healthier. If your smartwatch sends a heart alert, treat it as a reason to call your doctor, not as a diagnosis.
Heart rhythm problems
Your heart has its own electrical system that keeps it beating in a steady rhythm. Several studies looked at what to do when that system has problems.
A better kind of pacemaker: Some people need a pacemaker because the heart’s electrical signals get blocked (”heart block”). In about 700 such patients, placing the pacemaker wire so that it uses the heart’s own natural wiring worked better than the standard placement. Over about four years, around 8 out of 100 people with the newer method had a serious problem, such as weakening of the heart or a hospital stay for heart failure. With the standard method, it was around 19 out of 100.²⁹ Most of that difference came from preventing the heart muscle from weakening. The number of deaths was about the same.³⁰
After treatment for atrial fibrillation (AFib): AFib is a common irregular heartbeat. One treatment, called ablation, uses heat or cold to create tiny scars that block the faulty signals. In a study of 320 people in China with high blood pressure, AFib or a related rhythm problem came back less often when they took a combination medicine called sacubitril/valsartan (brand name Entresto) instead of valsartan alone: 18 out of 100 versus 28 out of 100.³¹
Extra scarring during ablation: Another study tested adding more spots during ablation. Overall, it didn’t help. It may help people who already have scarred areas in the heart.³²
CPR in the community: A five-year effort in North Carolina trained more than 200,000 people in CPR and coached 911 dispatchers to talk callers through it. Survival after sudden cardiac arrest didn’t improve overall: about 9 out of 100 survived and left the hospital with good brain function in both groups. But more bystanders stepped in to do CPR by the last year.³³
What this means for you:
If you need a pacemaker, ask whether the newer placement is right for you. If your current pacemaker works well, there’s no need to replace it.
If you’ve had an AFib ablation, ask your doctor whether your blood pressure medicine is the best fit.
And learn CPR. It’s still one of the most valuable skills anyone can have.
The big picture
Better numbers don’t always mean better health. Several new drugs improved blood tests but didn’t prevent heart attacks or strokes.
Goals should fit the person. The right blood pressure or cholesterol plan depends on your history.
Stopping a medicine has risks too. Don’t stop a statin or any heart medicine without talking to your doctor.
Stroke survivors have new options: a lower blood pressure goal and a newly approved clot-prevention medicine.
Pacemakers are getting smarter. A newer placement method protected the heart muscle better.
Technology is moving fast, but it’s still early. AI and smartwatches are promising, but they haven’t yet been shown to keep people healthier.
Healthy habits are still the foundation. Nothing presented this year replaces good food, regular movement, healthy sleep, and staying tobacco-free.
Questions to bring to your next appointment
What blood pressure number should I aim for, and why?
Why am I taking a statin, and what would happen if I stopped?
What are my “bad” cholesterol (LDL) and Lp(a) levels?
Could I have sleep apnea? Should I get a sleep test?
I’ve had a stroke. Do these new findings apply to me?
If I need a pacemaker, is the newer method an option for me?
You don’t need to memorize new drug names or study results. What matters is whether a study answered a question that looks like your own situation. The best use of new research isn’t to change everything at once. It’s to help you and your doctor make your next decision a little better informed.
