Left ventricular assist device relieves severe heart failure

Release date: 2007-04-24

A groundbreaking development in treating severe heart failure has emerged from the UK, where researchers have discovered that direct cardiac drug therapy can significantly improve outcomes for patients with the most advanced stages of the condition. This innovative approach involves a battery-powered pump known as a left ventricular assist device (LVAD), which is implanted into the left ventricle to deliver medication directly to the heart muscle. The study, published in the prestigious New England Journal of Medicine, highlights the potential of this method as a game-changer in heart failure treatment.

In the trial, 15 patients suffering from severe heart failure were given this experimental therapy. All of them had previously required an auxiliary device to support their heart function. Following the treatment, 11 patients were successfully weaned off the LVAD, and nine of them remained free from heart failure for up to four years. This is particularly impressive, as patients with advanced heart failure typically face an annual mortality rate exceeding 25%. The results offer new hope for those struggling with this life-threatening condition.

This breakthrough not only demonstrates the effectiveness of targeted drug delivery but also opens the door to more personalized and effective treatments for heart failure. As research continues, it's possible that similar therapies could become a standard option for many patients in the future. ——China Medical News
