Figure 1.

Kaplan–Meier survival curves of cardiac mortality (according to the defined primary endpoints in Methods) from diagnosis in the total cohort of HOCM patients managed. Conservative group (blue), short atrioventricular delay pacing (green), and myectomy (red). N at risk refers to number of patients left in Kaplan–Meier curve. As myectomy group is 25 years younger at the time of diagnosis, the lower attrition rate during early follow-up is to be expected but rapidly increases during later follow-up.
