Is acupuncture safe for a patient on anticoagulation (blood thinner) therapy with a history of pacemaker replacement?

From the Guidelines

Acupuncture can be safely administered to patients on anticoagulation therapy with a history of pacemaker replacement, provided that certain precautions are taken. For patients on blood thinners like warfarin, apixaban, rivaroxaban, or dabigatran, there is an increased risk of bleeding and bruising at needle insertion sites 1. While acupuncture is not absolutely contraindicated, the practitioner should use thinner needles, apply less manipulation, and avoid deep needling techniques, particularly in areas with major blood vessels. For patients with pacemakers, acupuncture needles should not be placed near the pacemaker site (typically the upper chest) or where electrical stimulation might be used, as this could potentially interfere with pacemaker function. Electroacupuncture should be completely avoided in pacemaker patients. Some key considerations for anticoagulation therapy include:

• The use of anticoagulants to prevent thromboembolism in patients with atrial fibrillation, with a focus on minimizing bleeding risks 1
• The importance of monitoring international normalized ratio (INR) levels in patients taking warfarin, with a target range of 2.0-3.0 1
• The potential for drug interactions between anticoagulants and other medications, including antiplatelet agents 1 Before proceeding with treatment, the patient should inform their acupuncturist about their anticoagulation medication and pacemaker, and the acupuncturist should consult with the patient's cardiologist. The acupuncturist should also monitor for excessive bleeding or bruising during and after treatment. With these precautions in place, many patients on anticoagulants with pacemakers can safely receive modified acupuncture treatments.

From the Research

Safety of Acupuncture for Patients on Anticoagulation and with a History of Pacemaker Replacement

• The safety of acupuncture for patients on anticoagulation therapy with a history of pacemaker replacement is a concern due to the potential risks of bleeding and pacemaker malfunction.
• A study published in 2011 2 found that electroacupuncture (EA) might be a safe alternative for patients with a pacemaker, as it did not cause any complications or side effects in a patient who received EA treatments over a period of 2 years.
• However, another study published in 1980 3 found that low frequency acupuncture can cause electromagnetic interference with demand pacemakers, which can lead to oversensing and other complications.
• In terms of anticoagulation therapy, a systematic review published in 2015 4 found that acupuncture appears to be safe in anticoagulated patients, with a low risk of bleeding complications (0.003%).
• The review also found that the risk of bleeding can be minimized by using appropriate needling location and depth.
• Another study published in 2013 5 found that the risk of pocket hematoma in patients with mechanical heart valves who underwent pacemaker or implantable cardioverter-defibrillator insertion was low (5.5%), and that predictors for pocket hematoma included replacement surgery and an international normalized ratio of 1.5 or higher on the day of surgery.

Considerations for Acupuncture Treatment

• Patients on anticoagulation therapy with a history of pacemaker replacement should be carefully evaluated before receiving acupuncture treatment.
• The use of electroacupuncture should be avoided in patients with pacemakers, as it may cause electromagnetic interference.
• Acupuncture points and techniques should be carefully selected to minimize the risk of bleeding and other complications.
• Patients should be closely monitored during and after acupuncture treatment for any signs of bleeding or other adverse effects.
• The benefits and risks of acupuncture treatment should be carefully weighed against other treatment options, such as conventional drug therapy or surgery.
