Researchers found that for people with a blockage in the left main coronary artery — the heart's most important supply line — the way doctors guide a stenting procedure may matter a great deal. Using imaging tools (like ultrasound inside the artery) to guide the stent placement was linked to fewer serious heart problems like heart attacks or strokes compared to using standard X-ray pictures alone, and it performed similarly to open-heart bypass surgery. This is early research and hasn't yet changed treatment guidelines.

PubMed · June 9, 2026
Researchers found that the point at which people with stable coronary artery disease — a condition where the heart's arteries are narrowed — actually start feeling chest pain (angina) corresponds to much lower pressure readings in the heart's arteries than doctors previously assumed, and that this threshold shifts depending on how hard the heart is working during exercise. This matters because doctors currently use these pressure measurements to decide whether to open a blocked artery with a procedure, and this research suggests those decision points may need to be reconsidered. This is early research and hasn't yet changed treatment guidelines.

PubMed · June 3, 2026
Researchers found that for people with coronary artery disease — a condition where the arteries supplying the heart become narrowed — different types of exercise affect blood vessel health in different ways. High-intensity interval training (short bursts of harder effort mixed with rest) and combined exercise programs done at high intensity showed the strongest improvements in how well blood vessels open and relax, which is an important sign of heart health. This is early research and hasn't yet changed treatment guidelines.
Ask your doctor: Ask the doctor whether the patient should focus on high-intensity interval aerobic exercise like running or cycling, since research shows it might improve blood vessel function better than moderate-intensity or resistance training.

Researchers found that people with coronary artery disease — a condition where the arteries supplying blood to the heart become narrowed — who did one hour of structured football (soccer) training per week for a year saw real improvements in their heart fitness, high blood pressure, weight, and even mood, compared to those who didn't play. The football group also needed fewer blood pressure medications over time, while the non-playing group needed more. This is early research and hasn't yet changed treatment guidelines.
Lifestyle
AHA Guidelines · June 1, 2026
A study found that regularly moving your body — through activities like walking, cycling, or other exercise done on a consistent basis — improves several health measures in people with overweight or obesity, including blood pressure, how well the body responds to insulin (which helps manage blood sugar), cholesterol levels, and heart and lung fitness. Importantly, researchers found these benefits happen regardless of whether a person loses weight. This means that getting active regularly can improve how the body works on the inside, even when the number on the scale doesn't change.

AHA Guidelines · June 1, 2026
Researchers found that adults with obesity who exercise regularly — meaning consistent physical activity as a habit, not just occasional movement — can improve their high blood pressure, cholesterol, and how well their body handles blood sugar, even if the number on the scale doesn't change. The benefits came from the activity itself, not from losing weight. This suggests that staying active has real health value for people with obesity beyond just burning calories.

A study found that for people who have a heart attack affecting a major artery (called a STEMI) and also have blockages in other heart arteries, it didn't clearly matter whether doctors treated those other blockages during the same procedure or in a separate follow-up procedure — the rates of serious heart problems like heart attacks or strokes, and death, were similar either way. Researchers analyzed eight studies involving over 5,000 patients to reach this finding. People in this situation might find it helpful to ask their doctor which approach makes the most sense for their specific circumstances, since the research suggests there may be flexibility in timing.

PubMed · June 1, 2026
A study found that when people with suspected coronary artery disease (a condition where the arteries supplying the heart become narrowed) had an abnormal heart scan and then went on to have a follow-up stress imaging test, those tests only detected the problem about 63% of the time — meaning they missed roughly 1 in 3 cases of significant blockages. More sophisticated imaging tests were better at catching real problems but also more likely to flag concerns in people who didn't actually have dangerous blockages. This is early research and hasn't yet changed treatment guidelines.
What's New
PubMed · June 1, 2026
Researchers found that in people with coronary artery disease — where the heart's arteries are narrowed or blocked — using a special drug-coated balloon to open a tricky type of blockage (at a spot where an artery splits into two branches) may lead to fewer serious heart problems like heart attacks or strokes compared to leaving a small metal tube called a stent in place. The balloon delivers medicine directly to the artery wall without leaving anything behind, and the analysis of nearly 900 patients also showed the treated artery was less likely to narrow again over time. This is early research and hasn't yet changed treatment guidelines.
Medications
PubMed · June 1, 2026
Researchers found that colchicine, an older anti-inflammatory medication, helped reduce serious heart problems like heart attacks or strokes — as well as the need for procedures to restore blood flow to the heart — in people with coronary artery disease (a condition where the arteries supplying the heart become narrowed or blocked). The analysis looked at 20 studies involving more than 21,000 patients and found that colchicine appeared beneficial across different stages of the disease, though it was also linked to a higher chance of stomach and digestive side effects. This appears to be a safety and effectiveness update, reinforcing colchicine as an option worth discussing with a doctor rather than introducing it as a brand-new treatment.
Ask your doctor: Ask the doctor whether colchicine might help reduce the patient's risk of heart problems long-term, or whether the research shows it mainly works for certain types of heart disease.

PubMed · June 1, 2026
A study found that pemafibrate, a medication used to lower high triglycerides (a type of fat in the blood), also reduced fibrinogen levels in people with coronary artery disease — a condition where the arteries supplying the heart become narrowed. Fibrinogen is a protein in the blood that helps clots form, and when levels are too high, it may raise the risk of dangerous clots that could lead to serious heart problems like heart attacks or strokes. This is early research and hasn't yet changed treatment guidelines.

PubMed · June 1, 2026
Researchers found that a low dose of colchicine — a well-known anti-inflammatory medication often used for gout — did not significantly reduce heart muscle thickening (when the heart's main pumping chamber becomes enlarged and stiff, a condition that raises the risk of serious heart problems) in people with coronary artery disease compared to a placebo. The study was cut short before enrolling enough participants, which means the results aren't conclusive — a small but meaningful benefit may still exist and just wasn't detectable here. This is early research and hasn't yet changed treatment guidelines.
What's New
PubMed · June 1, 2026
A study found that when treating a common complication called in-stent restenosis — where an artery that was previously opened with a small mesh tube starts to narrow again — balloons coated with a drug called sirolimus worked just as well as balloons coated with a drug called paclitaxel, with no meaningful difference in serious outcomes like heart attacks, death, or needing a repeat procedure to reopen the artery. Researchers pooled results from 11 studies involving more than 3,600 patients, which helps give a broader picture than any single study alone. This is early research and hasn't yet changed treatment guidelines.

PubMed · June 1, 2026
Researchers found that two types of heart stents — tiny mesh tubes placed in blocked arteries to keep them open — performed about the same when it came to serious outcomes like heart-related death, the stent getting blocked by a clot, or needing a repeat procedure on the same artery. One type, called a polymer-free stent, was thought to possibly be safer because it lacks a coating that some researchers worried could cause problems over time, but this large review of nearly 12,000 patients found no meaningful difference between the two. This is early research and hasn't yet changed treatment guidelines.
What's New
PubMed · June 1, 2026
A study found that for people who had a heart attack and had blockages in multiple heart arteries, treating all the blocked arteries (not just the one that caused the heart attack) reduced the combined risk of serious outcomes — including death, another heart attack, stroke, and needing another procedure — by about 8 percentage points. Researchers found there was a 99.8% probability that treating all blockages was genuinely better, and a strong chance the benefit was large enough to truly matter in everyday life. This gives patients with multiple blocked heart arteries a good reason to ask their doctor whether treating all their blockages at once might be the right approach for them.
Lifestyle
PubMed · May 30, 2026
Researchers looked at 23 studies involving over 1,700 people with coronary artery disease — a condition where the arteries supplying the heart become narrowed — and compared different types of exercise, including steady aerobic activity (like walking or cycling), high-intensity interval training (short bursts of hard effort followed by rest), strength training combined with aerobic exercise, and traditional Chinese movement practices like Tai Chi. They found that all of these exercise approaches meaningfully improved how well the heart and lungs work together, including how much oxygen the heart pumps out with each beat and how efficiently the body uses oxygen during activity. The combination of aerobic exercise with resistance (strength) training and high-intensity interval training showed some of the strongest improvements in heart function among people with this condition.
Guidelines
JAMA · May 26, 2026
According to the American College of Cardiology and American Heart Association guidelines, people with acute coronary syndrome — a term that covers serious, sudden heart problems like a heart attack or dangerous chest pain caused by blocked blood flow to the heart — should receive specific, time-sensitive treatments to restore that blood flow as quickly as possible. These guidelines matter because acting fast during a heart event can mean the difference between a full recovery and lasting heart damage. People experiencing sudden chest pain or pressure should contact emergency services immediately so care can begin right away.
Ask your doctor: Ask the doctor whether the patient's current treatment plan for coronary artery disease follows the latest 2025 guidelines from the ACC/AHA for managing acute coronary syndrome.
Medications
ScienceDaily · May 25, 2026
A study found that beta blockers — a type of medication that slows the heart rate and lowers blood pressure, commonly given after a heart attack — did not actually help patients whose heart was still working normally after an uncomplicated heart attack. Researchers also found that women in the study who took these drugs had a higher chance of death, another heart attack, or being hospitalized for heart failure compared to women who did not take them. This appears to be a new finding that challenges how these medications have been used for decades.
Ask your doctor: Ask the doctor whether the patient actually needs to keep taking their beta blocker if their heart function has stayed normal after a heart attack, or whether the risks might outweigh the benefits.

PubMed · May 25, 2026
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.
Ask your doctor: Ask the doctor whether the patient should take just a blood thinner alone or a blood thinner plus aspirin for their coronary artery disease.

Researchers found that people with coronary artery disease — a condition where the heart's main arteries are narrowed — may not all benefit equally from a procedure called PCI (where a small tube is inserted to open blocked arteries). Specifically, patients whose tiny blood vessels inside the heart were functioning well on their own (low resistance to blood flow) were more likely to exercise longer after the procedure compared to those whose small vessels were already struggling. This suggests that measuring the health of those tiny heart vessels beforehand might one day help doctors identify who is most likely to benefit from the procedure. This is early research and hasn't yet changed treatment guidelines.
Medications
ScienceDaily · May 21, 2026
A large international review found that a diabetes medication like Ozempic — also used for weight loss — significantly lowers the chances of serious heart problems like heart attacks or strokes, heart failure, and early death in people with type 2 diabetes. Researchers believe these medications could play a major role in protecting heart health, beyond just managing weight and blood sugar. This appears to be an emerging finding about a broader benefit of medications that were already in use.
What's New
PubMed · May 20, 2026
Researchers found that a non-invasive CT scan test — which measures blood flow through narrowed heart arteries without needing a catheter — can help predict who is more likely to experience serious heart problems like heart attacks or strokes. Across 22 studies involving more than 20,000 people with coronary artery disease (a condition where the arteries supplying the heart become narrowed or blocked), those whose scan showed reduced blood flow were nearly four times more likely to have serious heart problems than those whose scan looked normal. This matters because it suggests the test could one day help doctors identify higher-risk patients earlier and more safely — but this is early research and hasn't yet changed treatment guidelines.

Researchers found that among people with chronic coronary artery disease — a condition where the heart's blood vessels are narrowed — more than 4 in 10 still experienced chest pain (called angina) within six months, even after a procedure was done to fully restore blood flow to their heart. Those with lingering chest pain reported a lower quality of life compared to those whose chest pain resolved. This is early research and hasn't yet changed treatment guidelines.
Guidelines
PubMed · May 19, 2026
According to European Society of Cardiology (ESC) guidelines, combining aspirin with rivaroxaban — a blood-thinning medication — is recommended for people with chronic coronary syndrome, which means long-term heart disease caused by narrowed arteries. The guidelines were updated in 2024 to better identify which patients are at higher risk of serious heart problems like heart attacks or strokes. This combination approach appears to help reduce the risk of serious heart problems and death across a broad range of patients, which is why their doctor may consider it an important part of managing ongoing heart disease.
Ask your doctor: Ask the doctor whether the patient should be taking both aspirin and rivaroxaban together if the patient is considered high-risk for heart problems based on the newest heart disease guidelines.

PubMed · May 19, 2026
Researchers found that for people recovering from a serious heart event, gradually stepping down blood-thinning medication — guided by a test that checks how 'sticky' a patient's blood platelets are — appeared to be similarly safe whether patients were considered high-risk or lower-risk for future serious heart problems like heart attacks or strokes. High-risk patients (such as older adults or those with diabetes or kidney problems) did have more complications overall, but the step-down approach didn't seem to make things worse for them compared to staying on the stronger medication. This is early research and hasn't yet changed treatment guidelines.

PubMed · May 16, 2026
Researchers found that older competitive athletes — people aged 35 and up who train regularly and seriously — still develop significant buildup in their coronary arteries (the blood vessels that supply the heart), even though they exercise far more than most people. In fact, years of intense endurance training may actually be linked to certain changes in the arteries that could raise the risk of heart disease over time. This is early research and hasn't yet changed treatment guidelines.

Researchers found that people with lupus — an autoimmune disease where the body's immune system attacks its own tissues — appear to be more than twice as likely to develop coronary artery disease (a condition where the arteries that supply blood to the heart become narrowed or blocked) compared to people without lupus. This finding came from combining data across 13 studies involving millions of participants, and was also supported by a type of genetic analysis designed to test whether the link is truly causal, meaning lupus itself may be contributing to the increased heart risk rather than just happening alongside it. This is early research and hasn't yet changed treatment guidelines.

PubMed · May 15, 2026
Researchers found that for people with a blockage in a major heart artery called the left anterior descending artery — often called the 'widow maker' because of how important it is — a drug-coated balloon was linked to a higher rate of serious heart problems like heart attacks or the need for repeat procedures compared to a drug-eluting stent (a tiny mesh tube coated with medicine that props the artery open). Both are tools doctors use during a procedure to open narrowed or blocked arteries, but in this study, the stent appeared to perform better over two years, especially when the blockage was in the upper portion of that key artery. This is early research and hasn't yet changed treatment guidelines.

PubMed · May 8, 2026
Researchers found that among people with coronary artery disease — a condition where the arteries supplying the heart become narrowed — about 6 in 10 were open to using a health app to help manage their condition, and 8 in 10 had a positive attitude toward the idea. This suggests many patients are interested in using smartphone apps to stay on top of their heart health between doctor visits, which could open doors for better day-to-day self-care. This is early research and hasn't yet changed treatment guidelines.

Researchers found that older adults recovering from open-heart bypass surgery — a procedure that reroutes blood flow around blocked heart arteries — had better outcomes when they used a telehealth program after going home, compared to those who received standard discharge care alone. The program included a smartphone app to monitor their health at home and scheduled video calls with their care team, and it was linked to improved ability to carry out daily activities, lower levels of anxiety and depression, and fewer returns to the hospital. This is early research and hasn't yet changed treatment guidelines.
