Methods: Patients with HF were selected from consecutive HF admissions from 2008 to 2012. Groups were divided into: no follow-up TTE; routine < 1 year with no change in status ("rarely appropriate"), ≥ 1 year follow-up with no change in status ("maybe appropriate") and TTE due to change in clinical status ("appropriate"). Survival analysis was performed for the combined endpoint of HF readmission and death, and a separate analysis was performed for HF readmission, with death as a competing risk.
Results: Of 550 HF patients, 141 had a follow-up TTE, including 41 (29%) within 1 year. The event-free time in years was similar between no TTE (1.10 years [95%CI: 0.69, 1.49], routine TTE < 1 year (2.61 years [95% CI: 1.08, 3.04], routine > 1 year (2.45 years [95% CI: 1.37, 5.78]); all were greater than symptomatic patients (0.09 years [95% CI: 0.02, 1.80]). HF readmission was independently associated with statins, renal disease, coronary angiography and NYHA class, but not follow-up TTE timing. There were no differences in the cumulative incidence for death between groups. There were no differences in change in management in routine TTE < 1 year and ≥ 1 year.
Conclusion: The distinction of appropriateness of routine repeat TTE in stable HF patients, based on testing < 1 or ≥ 1year after index admission appears unjustified.
