A recent trial suggests that many breast cancer survivors who developed heart problems as a side effect of their treatment may no longer require lifelong medication. This finding is considered highly encouraging for thousands of patients whose heart health has been impacted by life-saving therapies.
Some cancer treatments can weaken the heart, necessitating medication to protect it. However, the new study, funded by the British Heart Foundation, followed 90 women at four hospitals whose heart function had improved after a specific breast cancer treatment. Most of these participants were between 40 and 50 years old and had previously been advised to continue taking heart medication indefinitely due to concerns about potential declines in heart function if they stopped.
Researchers found that after one year, 98 percent of patients who discontinued their heart medication experienced no change in their heart function. Only one woman in the group developed an issue with her heart's pumping ability. Additionally, women who stopped the medication reported an improved quality of life.
Professor Charlotte Manisty, who led the trial and is head of clinical cardiovascular science at University College London, noted that while modern breast cancer treatment is successful, its cardiac side effects present challenges. "Our study provides the first evidence that heart failure therapies can be safely stopped in survivors whose hearts have recovered, with the support of close monitoring," she stated, expressing hope that the findings would offer reassurance and a vision of a future less burdened by ongoing treatment.
One participant, Lucy Shepherd, 39, shared her experience, saying that being part of the trial and stopping heart medication significantly improved her life. Diagnosed with breast cancer at 33, her heart function had declined during treatment, leading to prescribed medication. "Being part of the trial and having the chance to come off heart medication has definitely improved my life," she said. "It has helped me to trust my body again."
The trial participants will continue to be monitored for their heart health over the next five years. Dr. Sonya Babu-Narayan of the British Heart Foundation highlighted the study's potential impact. "These findings will be hugely encouraging for the thousands of survivors... The study results give hope that many women will be able to safely stop taking medicines once their heart has recovered," she said, while also noting that further research and longer-term follow-up are necessary.
