Outcomes in Takotsubo Syndrome and Associations with Medication Use

In an observational study, cardiovascular and noncardiovascular death rates were elevated, and inhibitors of the renin-angiotensin system were the only cardiovascular medications associated with reduced risk.

In takotsubo syndrome (TS) — also called stress cardiomyopathy or broken heart syndrome — long-term mortality is elevated, similar to that after acute myocardial infarction (AMI), but for unclear reasons. Additionally, evidence-based therapies are lacking for TS. To explore causes of death and the effects of heterogeneous therapies for TS, investigators in Scotland compared outcomes between 620 patients with TS, 620 matched patients presenting with AMI, and 2480 matched individuals from the general population. Median follow-up was 5.5 years.

Among patients with TS, all-cause mortality was higher compared with the general population (hazard ratio, 1.8), both for cardiovascular causes (HR, 2.5) and noncardiovascular causes (HR, 1.5), but was l…
