Reversible Ventricular Dysfunction Takotsubo Cardiomyopathy
Key result
Takotsubo cardiomyopathy was characterized by reversible left ventricular dysfunction that normalized in 92.3% of patients within a mean of 16.9 days, with no recurrences over 0.5 to 5 years.
Population
13 elderly patients with normal coronary arteries and takotsubo-like left ventricular dysfunction
Design
Cohort
Follow-up
0.5 to 5 years

Implication
Describes takotsubo features in small elderly cohort; hypothesis-generating and requires validation in larger studies.

Population
13 elderly patients (mean age 75.3 years, 85% female) with normal coronary arteries and takotsubo-like left ventricular dysfunction, followed for 0.5 to 5 years.

Outcome
Detailed clinical features, recovery time of left ventricular wall motion, and recurrence of cardiac events
Takotsubo cardiomyopathy is a rapidly reversible form of acute heart failure with a generally good prognosis and low recurrence rate.
Cite This Study
Akashi et al. (2005) conducted an observational in Takotsubo cardiomyopathy (n=13). Takotsubo cardiomyopathy was evaluated on Normalization of left ventricular wall motion. Takotsubo cardiomyopathy was characterized by reversible left ventricular dysfunction that normalized in 92.3% of patients within a mean of 16.9 days, with no recurrences over 0.5 to 5 years.
