Introduction:Takotsubo cardiomyopathy is characterized by significant transient left ventricular dysfunction that is not due to obstructive coronary artery disease, but concurrent right ventricular (RV) dysfunction has been described previously. The aim of our study was to investigate the rates and outcomes of patients diagnosed with Takotsubo cardiomyopathy with RV dysfunction in the Veteran Affairs (VA) system.Methods:We performed a retrospective study using chart review for patients diagnosed with Takotsubo cardiomyopathy between 2005 and 2018 in the VA national database. We included patients who met the Mayo Clinic diagnostic criteria for Takotsubo cardiomyopathy. We collected data for demographics, clinical course, and outcomes.Results:276 patients (70% males) were included. Median age was 64 years, 18.5% were known to have coronary artery disease, 34.8% had Diabetes and 58.1% had hypertension. 96.3% of patients had apical variant of Takotsubo cardiomyopathy. Biventricular dysfunction was identified in 14.1% of patients; of those 71.8% were identified as new RV dysfunction in which 92.3% were apical. There was no significant difference in the in-hospital mortality rates between patients with new biventricular dysfunction compared to patients with normal RV function or old RV dysfunction (10.7% vs 8.1%, p = 0.63). There was also no significant difference in 30-day mortality rates between patients with new biventricular dysfunction compared to patients with normal RV function or old RV dysfunction (4.2% vs 1.8%, p = 0.45). Similar findings were observed when patients with previous RV dysfunction were excluded. On follow up echocardiogram 96.3% of patients who survived had full recovery of their RV function.Conclusions:In patients diagnosed with Takotsubo cardiomyopathy with new RV dysfunction, there was no significant difference in mortality rates in the hospital or at 30-day follow up. |
