Longevity & AgingHeart Microcurrent Implants Show Early Promise but Need Stronger Evidence
Cardiac microcurrent therapy uses an implanted device to deliver tiny electrical currents intended to improve a weakened heart’s function. Early findings presented at a heart failure conference suggest improvements in symptoms, pumping ability, and exercise capacity. A blinded laboratory reassessed exercise tests from 42 patients in a randomized trial and found benefits on some measures, although the difference in absolute peak oxygen uptake did not reach statistical significance. Researchers propose that the currents could reduce scarring activity and stiffness in heart muscle, but that explanation remains unproven. Specialists questioned the unusually large reported improvements while supporting further research. A version implanted under the skin is also being explored, but the supplied article cuts off before its results. For now, the findings justify larger trials, not replacing established heart failure treatment.
