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.
