Higher Hospital Admissions in Takotsubo Cardiomyopathy During Late Summer

Although more women are admitted with Takotsubo cardiomyopathy, more men ultimately die.

Late summer is the most common time of year for hospital admissions for patients with Takotsubo cardiomyopathy, according to research presented at the 66th Annual Scientific Sessions & Expo of the American College of Cardiology in Washington, DC.

Researchers from Mount Sinai St. Luke’s Hospital in New York City conducted a retrospective cohort study using data from the 2013 National Independent Sample; the admitting diagnosis for adult patients was stress-induced cardiomyopathy.

Data from 7070 patients with Takotsubo cardiomyopathy were included in the study (90% women; mean age, 66 years); 1.6% died during their hospital stay. 

The probability of inpatient mortality was higher in male patients (85%; risk ratio, 0.15; P <.001). About 7% of male patients died vs 1% of female patients.

The researchers identified July, August, and September as the months with the highest numbers of Takotsubo cardiomyopathy admissions; however, most men were admitted in May, and most women were admitted in July (14% and 10.6%, respectively).

“Even though 90% of patients…admitted to the hospital are female, the mortality is higher among males,” the researchers concluded.
