TOPLINE:
Mortality in patients with takotsubo syndrome (TTS), sometimes called broken heart syndrome or stress-induced cardiomyopathy is substantially higher than that in the general population and comparable with that in patients having myocardial infarction (MI), results of a new case-control study showed. The rates of medication use are similar for TTS and MI, despite no current clinical trials or recommendations to guide such therapies, the authors noted.
METHODOLOGY:
- The study included 620 Scottish patients (mean age, 66 years; 91% women) with TTS, a potentially fatal condition that mimics MI, predominantly affects middle-aged women, and is often triggered by stress.
- The analysis also included two age-, sex-, and geographically matched control groups: Representative participants from the general Scottish population (1:4) and patients with acute MI (1:1).
- Using comprehensive national data sets, researchers extracted information for all three cohorts on prescribing of cardiovascular and noncardiovascular medications, including the duration of dispensing and causes of death, and clustered the major causes of death into 17 major groups.
- At a median follow-up of 5.5 years, there were 722 deaths (153 in patients with TTS, 195 in those with MI, and 374 in the general population cohort).
TAKEAWAY:
- and slightly lower than that in patients having MI (HR, 0.76; 95% CI, 0.62-0.94; P = .012), with cardiovascular causes, particularly heart failure, being the most strongly associated with TTS (HR, 2.47; 95% CI, 1.81-3.39; P < .0001 vs general population), followed by pulmonary causes. Noncardiovascular mortality was similar in TTS and MI.
- Prescription rates of cardiovascular and noncardiovascular medications were similar between patients with TTS and MI.
- The only cardiovascular therapy associated with lower mortality in patients with TTS was angiotensin-converting enzyme inhibitor or angiotensin receptor blocker therapy (P = .0056); in contrast, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, beta-blockers, antiplatelet agents, and statins were all associated with improved survival in patients with MI.
- Diuretics were associated with worse outcomes in both patients with TTS and MI, as was psychotropic therapy.
IN PRACTICE:
“These findings may help to lay the foundations for further exploration of potential mechanisms and treatments” for TTS, an “increasingly recognized and potentially fatal condition,” the authors concluded.
In an accompanying comment, Rodolfo Citro, MD, PHD, Cardiovascular and Thoracic Department, San Giovanni di Dio e Ruggi d’ Aragona University Hospital, Salerno, Italy, and colleagues said the authors should be commended for providing data on cardiovascular mortality “during one of the longest available follow-ups in TTS,” adding the study “suggests the importance of further research for more appropriate management of patients with acute and long-term TTS.”
SOURCE:
The research was led by Amelia E. Rudd, MSC, Aberdeen Cardiovascular and Diabetes Centre, University of Aberdeen and NHS Grampian, Aberdeen, Scotland. It was published online in the Journal of the American College of Cardiology.
LIMITATIONS:
Complete alignment of all variables related to clinical characteristics of patients with TTS and MI wasn’t feasible. During the study, TTS was still relatively unfamiliar to clinicians and underdiagnosed. As the study used a national data set of routinely collected data, not all desirable information was available, including indications of why drugs were prescribed or discontinued, which could have led to imprecise results. As the study used nonrandomized data, causality can’t be assumed.
DISCLOSURES:
Dr. Rudd had no relevant conflicts of interest. Study author Dana K. Dawson, Aberdeen Cardiovascular and Diabetes Centre, University of Aberdeen, Scotland, declared receiving the Chief Scientist Office Scotland award CGA-16-4 and the BHF Research Training Fellowship. Commentary authors had no relevant conflicts of interest.
