Seven-point system gauges seriousness of heart failure in elderly

A simple points system may soon help guide treatment of elderly heart failure patients. Researchers at the School of Medicine found that by counting how many of seven easy-to-obtain health factors a patient has, physicians can estimate the patient’s risk of dying.

High-energy clamp simplifies heart surgery for atrial fibrillation

This illustration of the Cox-Maze procedure shows the ablation lines in the left atrium.Heart surgeons at the School of Medicine have helped usher in a new era in the surgical treatment of atrial fibrillation. Using radiofrequency devices — rather than a scalpel — they’ve greatly shortened the surgery and made it significantly easier to perform. WUSM surgeon Ralph J. Damiano Jr. and colleagues have played a vital role in developing the devices, which deliver high-energy waves to heart tissue and very quickly create scars or ablations.

Heart failure linked to altered communication channels

Bright areas in this image highlight the junctions between heart muscle cells.Failing hearts develop interference in their communication channels, according to research conducted at the School of Medicine. The problem involves a subtle change in the pores that connect heart muscle cells. When the scientists duplicated this change in mice, the mice became susceptible to ventricular tachycardia, a dangerous heart rhythm disorder that can lead to sudden cardiac death.
