A recent study conducted in Austria suggests that gentle shockwaves could help regenerate the heart tissue of patients who have undergone bypass surgery. This study involved 63 participants and found that those who received the new shockwave treatment were able to walk further and their hearts were able to pump more blood. The lead researcher, Prof Johannes Holfeld, from Innsbruck Medical University, stated that this could potentially help millions of people and is the first time that heart muscle regeneration has been observed in a clinical setting. Larger trials of this device, which has been dubbed a “space hairdryer,” are now being planned to confirm these promising results in a larger group of patients.
Heart disease is a leading cause of death globally, with around 18 million people dying from heart disease or cardiovascular complications every year, according to the World Health Organization. Risk factors for heart disease include high blood pressure, unhealthy diet, tobacco, and alcohol use. While there is no cure for heart disease, treatments such as drugs and surgery can help manage the condition and reduce the risk of heart attacks. One common surgical procedure for severe cases of heart disease is bypass surgery, where a healthy blood vessel is attached to the heart to bypass blocked arteries. However, this procedure can only preserve heart function and does not improve it.
Researchers in Austria have been exploring the use of shockwave therapy to regenerate damaged heart tissue after bypass surgery. This therapy involves the application of mild soundwaves to stimulate the growth of new vessels around areas of the heart that have been damaged or scarred. Similar shockwave techniques are already used to treat conditions such as injured tendons and ligaments, as well as erectile dysfunction. The study conducted by Prof Johannes Holfeld and his team in Innsbruck involved bypass patients who received shockwave therapy under general anesthesia, while others underwent a fake procedure. Results showed that a year after surgery, the shockwave group had a higher increase in oxygenated blood pumped by the heart and were able to walk further without resting.
Dr. Sonya Babu-Narayan, associate medical director of the British Heart Foundation, noted that the current treatment for heart disease still has room for improvement and that the results of the study are promising. Patients who received shockwave therapy during their operation showed better heart function and fewer symptoms a year later compared to those who did not receive the therapy. Dr. Babu-Narayan emphasized the need for larger and longer trials to further investigate the long-term effects of this treatment. The researchers expect European regulators to approve the device later this year, with plans to use it on patients outside of clinical trials starting in 2025.
Funding for the study was provided by Austrian government departments, the US National Heart, Lung, and Blood Institute, and a company spun off from Innsbruck Medical University that is part-owned by the researchers. The potential of shockwave therapy in regenerating heart tissue after bypass surgery could offer new hope for patients with heart disease and improve their quality of life. Further research and trials are needed to confirm these findings and explore the long-term effects of this innovative treatment. Overall, this study represents a significant advancement in the field of cardiovascular medicine and has the potential to benefit millions of people worldwide.
