In the winter of 2004, women started arriving at Japanese hospitals complaining of chest pains and a shortness of breath. It was a month since a major earthquake had shaken the country, causing mudslides in the mountains, injuring 4,805 people and killing 68. In emergency rooms, doctors hooked the women up to ECG monitors, and saw the same extreme changes they’d expect with heart attacks. But subsequent tests showed their coronary arteries weren’t blocked, as they would be by a heart attack. Instead, their hearts had changed shape. It didn’t take long for these cases to be diagnosed as takotsubo cardiomyopathy, or “broken heart syndrome”.
Heartbreak is not simply a metaphor. Today, up to 7% of all sudden cardiac hospital admissions in Japan are diagnosed as takotsubo, when stress hormones after a traumatic event have caused a weakening of the left ventricle, meaning it can no longer pump effectively – for a while, it gives up. It hurts. And it clearly shows the link between the stresses happening in a person’s life, whether an earthquake or the end of a relationship, and their heart.
