Peripheral artery disease, which affects over 113 million people worldwide, can now be managed more effectively through a combination of exercise, medications, and lifestyle changes rather than relying solely on surgery. According to Gram Research analysis of current medical guidelines, supervised exercise therapy combined with smoking cessation, blood pressure control, cholesterol management, and antiplatelet medications can often delay or prevent the need for surgical intervention in people with leg artery disease.
Peripheral artery disease (PAD) affects over 113 million people worldwide, causing reduced blood flow to the legs and feet. According to Gram Research analysis, this condition often goes unnoticed because people don’t always feel symptoms, especially those with diabetes or kidney disease. A new specialist review from the British Cardiac Society outlines the latest approaches to diagnosing and treating PAD, emphasizing that exercise therapy, lifestyle changes, and medications can often prevent the need for surgery. The review highlights that early detection and aggressive management are crucial to preventing serious complications like amputation.
Key Statistics
Peripheral artery disease affects over 113 million people worldwide and is caused by atherosclerosis in more than 90% of cases, according to a 2026 specialist review published in Heart journal.
A 2026 review of current medical guidelines found that supervised exercise therapy is a cornerstone of treatment for claudication (leg pain when walking) and can often delay or avoid the need for revascularization surgery.
The 2024 American Heart Association/American College of Cardiology guidelines emphasize that peripheral artery disease management should integrate medical therapy, functional assessment, and timely intervention based on individual patient anatomy and preferences.
Dual pathway inhibitor medications reduce both cardiovascular events and limb complications in high-risk peripheral artery disease patients, according to current medical evidence reviewed in a 2026 Heart journal specialist article.

The Research Details
This is a specialist review article, not a new research study. Instead of testing something new, the authors examined all the current best practices and latest research about peripheral artery disease. They looked at how doctors diagnose the condition using physical exams, ultrasound, and imaging tests. They also reviewed the best treatment approaches, including lifestyle changes, medications, exercise programs, and when surgery is needed.
The review is based on the 2024 American Heart Association and American College of Cardiology guidelines, which represent the most current medical consensus. The authors organized their findings into a practical framework that doctors can use to help patients, emphasizing that treatment should be personalized based on each person’s specific situation and preferences.
This type of specialist review is important because it brings together all the latest research and guidelines into one clear document. Instead of doctors having to read hundreds of individual studies, they can use this review to understand the best current approaches. This helps ensure that patients receive consistent, evidence-based care no matter where they’re treated. The review also highlights that many cases of PAD are missed because symptoms aren’t always obvious, so it helps doctors know what to look for.
This review was published in Heart, a respected journal from the British Cardiac Society, which means it was reviewed by other medical experts before publication. The authors based their recommendations on established medical guidelines from major organizations like the American Heart Association. However, because this is a review of existing research rather than a new study, it doesn’t provide new experimental data—it synthesizes what we already know into practical guidance.
What the Results Show
The review confirms that peripheral artery disease is primarily caused by atherosclerosis (hardened arteries) in over 90% of cases. The condition affects more than 113 million people worldwide and is a serious health concern because it indicates broader heart and blood vessel problems throughout the body.
A key finding is that many people with PAD don’t realize they have it because symptoms aren’t always obvious. Some people feel leg pain when walking (called claudication), but others have no symptoms at all, especially those with diabetes or chronic kidney disease. This means doctors need to actively screen for PAD in high-risk patients rather than waiting for people to report symptoms.
The review emphasizes that the best first-line treatment combines several approaches: quitting smoking, controlling blood pressure, taking medications to lower cholesterol, eating a healthy diet, and doing supervised exercise programs. These lifestyle and medication approaches can often prevent or delay the need for surgery. When surgery or catheter-based procedures are needed, the choice depends on the patient’s anatomy, overall health, and personal preferences.
The review highlights that certain medications called dual pathway inhibitors can reduce both heart attacks and limb complications in high-risk patients. Physical examination and medical history remain the foundation of diagnosis, though imaging tests like ultrasound, CT scans, or MRI can provide more detailed information when needed. The review also notes that non-atherosclerotic causes of PAD are rare but important to recognize, especially in younger patients, as they may require different treatment approaches.
This 2026 review aligns with and updates the 2024 American Heart Association guidelines, representing the current standard of care. It reinforces the long-standing importance of exercise therapy and lifestyle modification while incorporating newer medication options. The emphasis on early detection and patient-centered decision-making reflects an evolution toward more personalized medicine compared to older approaches that relied more heavily on surgery.
As a review article rather than a new research study, this work doesn’t provide new experimental data. The recommendations are based on existing research, which may have varying quality levels. The review focuses on atherosclerotic PAD (the most common type) and gives less attention to rare non-atherosclerotic causes. Additionally, the effectiveness of treatments can vary significantly between individual patients based on their specific circumstances, so results may not apply equally to everyone.
The Bottom Line
If you have leg pain when walking or have risk factors for PAD (smoking, diabetes, high blood pressure, high cholesterol, or kidney disease), ask your doctor about screening. If diagnosed with PAD, start with lifestyle changes and medications rather than assuming you’ll need surgery—supervised exercise programs are particularly effective. Quit smoking if applicable, control your blood pressure and cholesterol, and follow your doctor’s medication recommendations. Surgery or catheter procedures should be reserved for cases where lifestyle and medication aren’t working or for advanced disease threatening limb loss. (Confidence: High—based on established medical guidelines)
Anyone with risk factors for PAD should care about this research, including smokers, people with diabetes, those with high blood pressure or high cholesterol, and people with chronic kidney disease. People over 65 should also consider screening. People with no risk factors and no leg symptoms have lower risk but should still be aware of warning signs. Those already diagnosed with PAD should definitely discuss these treatment approaches with their doctor.
Supervised exercise programs typically show improvement in walking distance within 3-6 months. Lifestyle changes like smoking cessation and diet improvement can show benefits within weeks to months. Medications take several weeks to reach full effectiveness. If these approaches aren’t working after 3-6 months, that’s when doctors typically consider surgery or catheter procedures. Long-term benefits continue as long as you maintain the lifestyle changes and take medications as prescribed.
Frequently Asked Questions
What is peripheral artery disease and how common is it?
Peripheral artery disease (PAD) is a condition where arteries in the legs become narrowed or blocked, reducing blood flow. It affects over 113 million people worldwide and is usually caused by atherosclerosis (hardened arteries). Many people don’t realize they have it because symptoms aren’t always obvious.
Can exercise really help prevent surgery for leg artery disease?
Yes, supervised exercise therapy is a cornerstone of treatment and can often delay or prevent the need for surgery. Combined with medications and lifestyle changes like quitting smoking and controlling blood pressure, exercise programs can significantly improve walking distance and reduce symptoms.
What are the warning signs of peripheral artery disease I should watch for?
Common signs include leg pain or cramping when walking that goes away with rest, numbness or weakness in the legs, cold feet, or slow-healing sores on the feet. However, many people have no symptoms at all, especially those with diabetes or kidney disease, so screening is important if you have risk factors.
Who should be screened for peripheral artery disease?
Anyone with risk factors should ask their doctor about screening, including smokers, people with diabetes, high blood pressure, high cholesterol, chronic kidney disease, or those over 65. Early detection allows for treatment before serious complications develop.
What medications are used to treat peripheral artery disease?
First-line treatment includes antiplatelet medications (like aspirin) combined with cholesterol-lowering drugs and blood pressure medications. For high-risk patients, dual pathway inhibitor medications can reduce both heart attacks and limb complications. Your doctor will choose medications based on your specific situation.
