Tóm tắt


Takotsubo cardiomyopathy is a condition of transient systolic dysfunction triggered by emotional or physical stress. Nowadays, Takotsubo cardiomyopathy is gaining attention and has been detected more frequently. However, there is no collected data on Vietnamese subjects. This study aims to describe the clinical characteristics of patients diagnosed with Takotsubo cardiomyopathy and determine of rates and independent risk factors for in-hospital mortality.


A retrospective andobservational study was conducted at the University Medical Center Ho Chi Minh City, involved 103 patients diagnosed with Takotsubo cardiomyopathy between January 2015 and June 2022. The diagnosis was made based on the revised Mayo Clinic diagnostic criteria.


The average age of the study population was 71.2±15.3 years, with females accounting for 64.1% of the patients. The most common comorbidities among the patients were hypertension (57.3%), diabetes mellitus (30.1%), ischemic heart disease (15.5%), and chronic obstructive pulmonary disease (15.5%). Acute heart failure was observed in 30.1% of the patients, while ventricular arrhythmias were present in 17.6% of cases. The majority of triggers were attributed to physical factors, including infection (37.9%), respiratory failure (18.4%), postoperative status (3.9%), and acute neurological disease (2.9%). The in-hospital mortality rate was 17.5%, and the independent risk factors were identified as acute heart failure (OR=20.657, 95%CI 2.306–185.008, p=0.007) and respiratory failure (OR=10.397, 95% CI 1.117–96.795, p=0.040).


Takotsubo cardiomyopathy patients have many comorbidities and are often triggered by physical factors. The in-hospital mortality rate is significant, with acute heart failure and respiratory failure identified as independent risk factors.
