Description
Some patients with atrial fibrillation keep a fast, irregular heartbeat despite drugs. One last resort treatment burns the heart's electrical relay node. A pacing defibrillator device is then implanted to keep both sides of the heart in step. Bagdat Akhyt and co-authors followed one hundred one such patients for five years at one center. Thirteen cardiovascular deaths occurred in that time. The team used machine learning methods to find which measures best predicted death.
Five measures carried the signal. They were how strongly the main pumping chamber squeezes, walking distance in six minutes, pressure in the lung artery, a relaxation measure, and the leakage of one heart valve. A model built on them classified outcomes with high accuracy. The authors are careful to call the analysis exploratory. They present the factors as candidates for personal risk checks and for designing future studies, not as settled rules.
