Live in a high-rise? Consider having your heart attack elsewhere: a study in the Canadian Medical Association Journal looks at “the relation between floor of patient contact and survival after cardiac arrest in residential buildings.” Their take-away was almost Onion-like in its obviousness: “the survival rate after out-of-hospital cardiac arrest was lower for patients residing on higher floors.” It literally took too long for help to arrive. Yet the authors also suggest devising “interventions aimed at shortening response times to treatment of cardiac arrest in high-rise buildings,” as this “may increase survival”—which sounds like an interesting design challenge.
