Ankle Brachial Index Test: A non-invasive procedure to measure blood pressure

Ankle Brachial Index Test
Do your legs ache while walking? It might not just be tired muscles. Poor blood flow could be the real issue. One simple test that can help to detect it early is the Ankle Brachial Index Test. This non-invasive screening compares blood pressure in your ankles and arms to check for peripheral artery disease (PAD). Catching PAD early prevents serious complications. Let’s walk you through what this test is, how it works, and how Dr. Achintya Sharma can help you take charge of your vascular health.

Why the Ankle Brachial Index Test Matters

Millions of people suffer from poor circulation without knowing it. When arteries in your legs start to narrow, you might feel pain, tingling, or numbness. If left untreated, it can raise your risk of serious heart problems or even stroke. The good news? A simple and pain-free test called the ankle brachial index (ABI) can help spot these issues early.

Ignoring symptoms or skipping routine vascular check-ups can be dangerous. The ABI test offers early warning signs before it’s too late. If you're over 50, smoke, or have diabetes, this test could be life-saving.

Understanding the ABI Test Procedure

Ankle Brachial Index Test

The ABI test procedure is straightforward. The whole test takes under 30 minutes and doesn’t involve any needles or discomfort. Here’s how it works:

  1. Blood Pressure Cuffs: A technician places cuffs on your arms and ankles.

  2. Ultrasound or Doppler Device: This measures blood flow in your limbs.

  3. Pressure Reading: The cuff inflates and deflates to record the pressure.

  4. Compare Ratios: The systolic pressure at the ankle is divided by the systolic pressure at the arm.

This ratio is your ankle-brachial index. A healthy ABI score usually falls between 1.0 and 1.4. If it’s lower than that, it might be a sign that your arteries are narrowed or blocked.

Who Should Take the ABI Test?

Anyone experiencing leg pain, numbness, or slow-healing wounds should consider an ankle brachial index test. It's especially recommended for:

  • People over 50 with a history of smoking

  • Diabetics

  • Patients with high blood pressure or cholesterol

  • Individuals with a family history of vascular disease

Who Can Perform the ABI Test?

The ABI test can be performed by:

  • Vascular specialists

  • Cardiologists

  • Trained general physicians

But who can perform the ABI test? Trained healthcare providers, including vascular specialists, cardiologists, and even general practitioners with vascular training, can administer the test.

Dr. Achintya Sharma, a leading name in vascular diagnostics, provides comprehensive ABI testing and interpretation. With deep expertise in PAD and circulatory health, he ensures accurate results and follow-up care tailored to your needs.

How to Calculate Ankle-Brachial Index

Curious about how to calculate the ankle-brachial index? Here's the simple formula:

ABI = (Ankle systolic pressure) / (Arm systolic pressure)

For example:

  • Right arm pressure: 120 mmHg

  • Right ankle pressure: 100 mmHg

  • ABI = 100 / 120 = 0.83

ABI Result Meaning:

  • 1.0 – 1.4: Normal

  • 0.91 – 0.99: Borderline

  • 0.41 – 0.90: Mild to moderate PAD

  • Less than 0.40: Severe PAD

This easy calculation gives a clear picture of how well blood is flowing in your lower limbs.

Conclusion

The ankle brachial index test is an easy but important way to catch blood flow problems before they become serious. Whether you're at risk for PAD or just want peace of mind, taking this test is a smart step toward better vascular health. With the expertise of professionals like Dr. Achintya Sharma, you can get accurate results and a clear treatment path if needed. Pay attention to what your legs are telling you — those small signs could mean something bigger. Take action today — your heart and legs will thank you.

Stent for Heart Blockage: A Life-Saving Solution

Image
When it comes to heart health, every second counts. Heart blockages are among the primary causes of heart attacks and serious cardiovascular problems worldwide. These blockages restrict blood flow, leading to severe health risks if untreated. Fortunately, modern medical advancements have introduced a revolutionary solution: “The Stent” . A stent is a small, life-saving device designed to open up blocked arteries and restore blood flow. How does it function, and what makes it so powerful? Let’s simplify it to understand its impact on saving lives, so you can understand its importance and how experts like Dr. Achintya Sharma played a crucial role in its success. The Silent Threat of Heart Blockage Heart blockages occur when fatty deposits of fat (lipids, such as cholesterol), Calcium, Cellular waste products, Proteins, Inflammatory cells (like white blood cells), also known as plaque, build up in the coronary arteries. These arteries carry oxygen-filled blood to your heart. When these a...

The Role of Exercise in Preventing Deep Vein Thrombosis

Image
  Deep Vein Thrombosis (DVT) is a condition that should not be overlooked, as it poses significant health risks if left untreated. This condition occurs when a blood clot forms in one of the deep veins in the body, typically in the legs. The clot can partially or completely block blood flow, causing discomfort and complications. If the clot dislodges and travels through the bloodstream to the lungs, it can lead to a life-threatening condition known as a pulmonary embolism (PE). Understanding the causes, symptoms, and prevention methods of DVT can help individuals take proactive steps to reduce their risk. Causes of Deep Vein Thrombosis Several factors can contribute to the development of Deep Vein Thrombosis. One of the most common causes is immobility. Prolonged periods of sitting or lying down, such as during long flights, car trips, or hospital stays, can slow blood flow and increase the risk of clot formation. Surgery, especially orthopedic procedures involving the legs, hips, ...

Feeling constant tingling in your feet? Don’t ignore it, here’s why.

Image
Have you ever felt a strange tingling in your feet that just won’t go away, no matter how you sit, stand, or move? Do your feet often feel cold, numb, or asleep for no clear reason? You might take it as tiredness, winter chill, or poor posture. But what if it signals something much more serious? That persistent tingling in feet could be your body’s first warning sign of artery blockage. This condition silently blocks blood flow and causes serious complications, including limb loss. Before you dismiss the discomfort, ask yourself: What if this small symptom is hiding a major threat? What tingling in the feet hides  When arteries start narrowing due to plaque buildup, it leads to a condition called Peripheral Artery Disease (PAD). This restricts blood flow to your feet and legs. The first red flag? You guessed it—tingling in feet. According to Dr. Achintya Sharma, a leading vascular expert, “Patients often ignore tingling in feet, not realizing that it could be their body's call for ...
