Researchers found that for people with peripheral artery disease (PAD) — a condition where narrowed arteries reduce blood flow to the legs — two types of minimally invasive treatments worked better than standard balloon angioplasty (a procedure that opens up blocked arteries) at keeping those arteries open and reducing the chances of them narrowing again: drug-coated balloons, which release medication to prevent re-narrowing, and drug-eluting stents, which are small mesh tubes coated with medication placed inside the artery. The study, which combined results from 21 smaller studies involving nearly 3,000 patients, also found that old-fashioned bare-metal stents (mesh tubes without any medication coating) were linked to lower rates of wound healing, which is especially concerning since people with PAD already face a higher risk of serious complications like amputation. This is early research and hasn't yet changed treatment guidelines.

Researchers found that a measurement called 'pedal acceleration time' — which uses an ultrasound to check how quickly blood flow picks up speed in the small arteries of the foot — may be a useful tool for spotting poor blood flow and predicting whether wounds will heal in people with peripheral artery disease (a condition where narrowed arteries reduce blood flow to the legs and feet). This could matter because the standard test currently used, called the ankle-brachial index, has known limitations for some patients, and a more reliable tool might help doctors catch serious problems — like a higher risk of amputation — earlier. This is early research and hasn't yet changed treatment guidelines.

Researchers found that people with a serious form of peripheral artery disease — where reduced blood flow puts a limb at risk — had better long-term results when treated with a special dissolving scaffold device compared to a standard balloon procedure called angioplasty, which simply opens up a narrowed artery. Over three years, the scaffold helped keep the treated artery open more often and reduced the need for repeat procedures, though both approaches kept limb loss rates similarly low. This is early research and hasn't yet changed treatment guidelines.

Researchers found that a cholesterol-lowering injection called a PCSK9 inhibitor (brand name Repatha, for example) may help protect the legs of people with peripheral artery disease — a condition where narrowed arteries reduce blood flow to the limbs. In a large study of over 3,700 patients, those who received this medication had significantly fewer serious limb complications, such as amputations, compared to those who did not. Smaller studies also suggested improvements in wound healing and the ability to walk. This is early research and hasn't yet changed treatment guidelines.

Researchers found that women with peripheral artery disease — a condition where narrowed arteries reduce blood flow to the legs — may benefit much more than men from a personalized approach to blood-thinning medication after a procedure to restore that blood flow. Specifically, when doctors used a detailed blood test called thromboelastography to tailor each patient's anti-clotting treatment, women were far less likely to need a major leg amputation within a year compared to women who received the standard one-size-fits-all treatment. This is early research and hasn't yet changed treatment guidelines.

Researchers found that for people with blocked arteries in the upper thigh area — a condition called peripheral artery disease — a traditional open surgery called endarterectomy (where a surgeon physically clears the artery) kept the artery open longer than placing a small mesh tube called a stent through a minimally invasive procedure. However, the stent approach was linked to a notably lower risk of death within a year, and patients who had the open surgery spent more time in the hospital and had higher rates of wound infections. This is early research and hasn't yet changed treatment guidelines.

A study found that for people with peripheral artery disease — a condition where narrowed arteries reduce blood flow, often to the legs — arm-crank exercise (pedaling with the arms instead of the legs) lowered blood pressure more after a workout than walking did, which could make it a useful option for those who struggle with leg pain during exercise. Both types of exercise caused a healthy temporary drop in blood pressure afterward, but the drop was roughly twice as large with arm cranking. This is early research and hasn't yet changed treatment guidelines.

Researchers found that regularly using a painless imaging scan called a duplex ultrasound — which uses sound waves to check blood flow — to monitor patients after a procedure to restore circulation in their legs may help keep those blood vessels open longer and reduce the chances of amputation. For people with peripheral artery disease, a condition where narrowed arteries reduce blood flow to the legs, catching problems early with this type of monitoring could make a meaningful difference in outcomes. This is early research and hasn't yet changed treatment guidelines.

Researchers found that simple nutritional scoring tools — which measure how well-nourished a person is based on blood test results — may help predict serious outcomes in people with peripheral artery disease (PAD), a condition where narrowed arteries reduce blood flow to the limbs. Specifically, people with PAD who showed signs of poor nutrition had a higher risk of death and limb amputation, while those with better nutritional status fared better. This is early research and hasn't yet changed treatment guidelines.

PubMed · June 16, 2026
A study looked at different blood-thinning medication combinations for people with peripheral artery disease — a condition where narrowed arteries reduce blood flow, usually to the legs — to see which worked best at preventing serious heart problems like heart attacks or strokes without causing too much bleeding. Researchers analyzed 17 studies involving over 44,000 people and found that certain combinations, including aspirin paired with a low dose of rivaroxaban or with ticagrelor, were linked to fewer serious heart problems compared to taking aspirin alone. This is early research and hasn't yet changed treatment guidelines.

PubMed · June 1, 2026
Researchers found that people with peripheral artery disease — a condition where narrowed blood vessels reduce blood flow to the limbs — who took a diabetes medication like Ozempic or Victoza had notably lower rates of serious limb complications, serious heart problems like heart attacks or strokes, and death compared to those who didn't take these medications, based on data from over 240,000 patients across six real-world studies. The reduction in stroke risk appeared especially consistent across the studies, and the benefits were most reliable in people who also had diabetes. This is early research and hasn't yet changed treatment guidelines.
Ask your doctor: Ask the doctor whether the patient should ask about taking a GLP-1 medication like semaglutide or tirzepatide, since recent research suggests these drugs might lower the risk of serious leg problems in people with peripheral artery disease.

A study found that for people with severe blocked arteries in the lower abdomen and pelvis, getting stents placed (small mesh tubes that prop open the arteries) led to a hospital stay nearly 6 days shorter on average compared to open bypass surgery, without any significant difference in short-term death, kidney problems, or how well the arteries stayed open over time. This could matter for someone with peripheral artery disease — a condition where arteries narrow and reduce blood flow to the legs — because a shorter hospital stay often means a faster, less disruptive recovery. This is early research and hasn't yet changed treatment guidelines.

A study found that people with peripheral artery disease — a condition where narrowed arteries reduce blood flow, usually to the legs — who watched immersive nature scenes through a virtual reality headset during a procedure to open those arteries reported significantly less pain and felt much calmer than those who didn't, and even had lower heart rate and blood pressure during the procedure. This matters because the procedure, called angioplasty (where a tiny balloon is used to widen a blocked artery), is typically done while the patient is awake, which can be stressful and uncomfortable. This is early research and hasn't yet changed treatment guidelines.

PubMed · June 1, 2026
Researchers found that using a special catheter tool to make tiny lengthwise cuts in a clogged artery — before widening it with a balloon coated in medication — helped keep the artery open and reduced serious complications in people with peripheral artery disease (a condition where narrowed arteries reduce blood flow to the legs). After the procedure, more than 9 out of 10 patients did not experience a dangerous tear in the artery wall, which is a common concern with this type of treatment. This is early research and hasn't yet changed treatment guidelines.

PubMed · June 1, 2026
Researchers found that people with a serious condition called critical limb ischemia — where blood flow to the legs is severely reduced, putting limbs at risk — had better long-term outcomes when treated with a special type of balloon procedure that delivers medication directly to the artery, compared to a standard balloon procedure. Over five years, patients who received the medication-coated balloon were more likely to be alive and had fewer serious complications overall. This is early research and hasn't yet changed treatment guidelines.
What's New
PubMed · June 1, 2026
Researchers found that for people with peripheral artery disease — a condition where narrowed arteries reduce blood flow to the legs — a treatment using a special coated balloon may result in fewer repeat procedures to reopen the same artery within the first year, compared to a small mesh tube (called a stent) that slowly releases medication. However, this advantage didn't hold up at the two-year mark, and there were no meaningful differences in survival, limb loss, or procedure success between the two approaches. This is early research and hasn't yet changed treatment guidelines.
Guidelines
PubMed (Guideline Reviews) · June 1, 2026
According to European Society for Vascular Surgery (ESVS) guidelines, doctors should reconsider using a type of medical device — balloons and stents coated with a drug called paclitaxel — when performing a procedure to improve blood flow in the leg arteries of people with peripheral artery disease (a condition where narrowed arteries reduce blood flow to the limbs). The guidelines now reflect updated evidence suggesting these coated devices don't improve quality of life or reduce the need for repeat procedures any better than uncoated devices, and there are concerns they may be linked to a higher risk of death over the long term. This matters because it could influence the type of treatment people with leg artery disease discuss with their doctor when considering their options.
Ask your doctor: Ask the doctor whether paclitaxel-coated balloons or stents are still recommended for treating the patient's leg artery blockages, or if the newer research has changed which treatment options might be safer.

Researchers found that a procedure called intravascular lithotripsy — which uses sound waves to break up calcium deposits that have hardened inside leg arteries — worked very well for people with peripheral artery disease (PAD), a condition where narrowed arteries reduce blood flow to the legs. Across 14 studies, the procedure succeeded more than 95% of the time and caused fewer serious complications, like artery tears or blockages, compared to other common techniques used to open stiff, calcified arteries. This is early research and hasn't yet changed treatment guidelines.
Medications
PubMed · May 1, 2026
A study found that people with peripheral artery disease (PAD) — a condition where narrowed arteries reduce blood flow to the legs — who had already undergone a previous procedure to restore that blood flow were at higher risk of serious complications, including limb-threatening emergencies and serious heart problems like heart attacks or strokes, compared to those having their first such procedure. Researchers found that adding a low dose of the blood-thinning medication rivaroxaban to standard aspirin therapy helped reduce these risks in both groups. People in this situation may want to ask their doctor whether this combination approach has been considered as part of their care.
Ask your doctor: Ask the doctor whether the patient should take low-dose rivaroxaban along with aspirin to help prevent problems after leg artery surgery, based on what the VOYAGER-PAD study found.

A study found that for people with a serious condition called chronic limb-threatening ischemia — where blood flow to the legs is so poor that wounds struggle to heal and limbs may be at risk — restoring blood flow directly to the area of the wound worked better than restoring it through an indirect route. Specifically, patients who had blood flow restored directly to their wound area were more likely to see their wounds heal at 3, 6, and 12 months after the procedure. This is early research and hasn't yet changed treatment guidelines.

Researchers found that a newer type of laser treatment called 'cold laser atherectomy' may be effective at clearing artery blockages in the legs — a problem that affects people with peripheral artery disease, where narrowed arteries reduce blood flow to the limbs and can cause pain, wounds, or worse. The study compared this cold laser approach to an older laser method and looked at how well it opened up blocked or narrowed arteries, as well as how patients fared over six months. This is early research and hasn't yet changed treatment guidelines.

Researchers found that roughly 1 in 18 Chinese adults between the ages of 30 and 89 — an estimated 4 million or more people — were living with peripheral artery disease (PAD) in 2023. PAD is a condition where the arteries that carry blood to the legs and other areas outside the heart become narrowed or blocked, which can cause pain, poor circulation, and serious complications. The researchers also found that prevalence varied significantly by region and province across China, suggesting that some areas may have a much higher burden of the disease than others. This is early research and hasn't yet changed treatment guidelines.
Guidelines
PubMed · April 1, 2026
According to the American College of Cardiology and American Heart Association (ACC/AHA) guidelines, doctors caring for people with peripheral artery disease — a condition where narrowed arteries reduce blood flow, usually to the legs — should follow specific standards for choosing medications and deciding which follow-up tests are needed after treatment. These guidelines exist to make sure that care based on the best available evidence is delivered consistently, no matter where or by whom a patient is treated. The goal is to give every patient the same high standard of care and to make it easier to measure whether that care is actually being provided.

Researchers found that a diabetes medication like Ozempic or Victoza may help people with type 2 diabetes and peripheral artery disease — a condition where reduced blood flow makes it harder to walk and can put limbs at risk. Specifically, people taking these medications were able to walk farther, and a large group of real-world patients had roughly half the risk of losing a limb compared to those not taking them. This is early research and hasn't yet changed treatment guidelines.
Ask your doctor: Ask the doctor whether the patient should know about GLP-1 receptor agonist medications like semaglutide or dulaglutide, since research shows they may help people with type 2 diabetes and poor blood circulation in the legs walk farther and reduce the risk of amputation.

Researchers found that for people with peripheral artery disease — a condition where narrowed arteries reduce blood flow to the legs — a procedure called atherectomy (which uses a small device to clear blockages in blood vessels) was linked to lower death rates and better procedure success compared to other common treatments like balloon angioplasty or stenting in the area behind the knee. Stenting, where a small mesh tube is placed to keep the artery open, also showed benefits in reducing the risk of amputation compared to standard balloon angioplasty alone. This is early research and hasn't yet changed treatment guidelines.

PubMed · April 1, 2026
Researchers found that a special type of temporary artery support called a bioresorbable scaffold — essentially a small mesh tube that props open a narrowed artery and then slowly dissolves on its own — showed promising results for people with peripheral artery disease affecting the blood vessels below the knee. After one year, about 90% of treated arteries remained open, and around 83% of patients saw meaningful improvement in their symptoms. This is early research and hasn't yet changed treatment guidelines.
What's New
PubMed · April 1, 2026
Researchers found that a specific type of wire mesh tube (called the Supera stent) used to prop open blocked leg arteries worked better than a comparison stent over one year — fewer arteries re-narrowed, and less often did patients need a repeat procedure to fix the same area. This matters for people with peripheral artery disease, a condition where arteries in the legs become narrowed or blocked, making walking painful, because better-performing stents could mean fewer repeat procedures and better blood flow to the legs. This is early research and hasn't yet changed treatment guidelines.

A study found that for people with peripheral artery disease — a condition where narrowed arteries reduce blood flow to the legs — the best minimally invasive treatment option may depend on exactly where the blockage is located and how severe the disease is. For example, researchers found that certain advanced devices worked better in the short term, while different ones held up better over two to three years. This is early research and hasn't yet changed treatment guidelines.
What's New
PubMed · April 1, 2026
Researchers found that people with peripheral artery disease — a condition where narrowed arteries reduce blood flow, usually to the legs — have a fairly high chance of experiencing restenosis (when a treated artery narrows again) after a minimally invasive procedure to open blocked vessels. By reviewing seven different prediction tools, researchers looked at which factors might help doctors identify who is most at risk for this re-narrowing before it happens, which could help doctors personalize care for each patient. This is early research and hasn't yet changed treatment guidelines.
What's New
PubMed · April 1, 2026
Researchers found that people with peripheral artery disease — a condition where narrowed arteries reduce blood flow, usually to the legs — almost always have calcium buildup in their artery walls, with some studies showing it in up to 97% of patients. The study also found that the *type* of calcium buildup differs depending on where in the leg it appears, and that having diabetes or severe limb-threatening poor circulation was linked to specific patterns of buildup. This matters because calcium in artery walls can make the disease harder to treat and may affect decisions about procedures to restore blood flow. This is early research and hasn't yet changed treatment guidelines.
