Clinical characteristics and outcomes of chronic heart failure in adult Takayasu arteritis: A cohort study of 163 patients.

Chronic heart failure (CHF) is a serious complication and a major cause of mortality in patients with Takayasu arteritis (TA). We aimed to explore the clinical features and long-term outcomes in TA patients with CHF. Adult TA patients admitted to our hospital between January 2009 to April 2018 were classified as HF and non-HF group. The adverse events were defined as a composite of all-cause mortality and hospitalization for HF. The outcome of the HF-group was further analyzed. A total of 61 HF patients and 102 non-HF patients were identified. In the HF group, the median age at assessment was 41.9 years, and female was predominant (82.0%). The multivariable logistic regression model revealed that pulmonary hypertension, aortic regurgitation, mitral regurgitation, level albumin, and uric acid were independently associated with CHF. After a median follow-up of 1347 days, 25 adverse events occurred in HF patients, and the 5-year event-free rate was 54.7%. The Cox model showed that coronary artery involvement, aortic regurgitation, without interventional treatment were related to adverse events. The 5-year event-free rate was not satisfying. Aggressive intervention may decreased the likelihood of adverse events in patients with CHF. • Chronic heart failure is not rare (11.4%) in adult patients with Takayasu arteritis. • Pulmonary hypertension and aortic regurgitation are associated with chronic heart failure in Takayasu arteritis. • Mortality is common in HF patients with low LVEF (< 50%), but re-hospitalization is common in HF patients with normal LVEF. • Patients with chronic heart failure may need more aggressive management and close follow-up.
