Early changes in clinical characteristics after emergency department therapy for acute heart failure syndromes: identifying patients who do not respond to standard therapy.
Clinical trials for acute heart failure syndromes (AHFS) have traditionally enrolled patients well after emergency department (ED) presentation. We hypothesized a large proportion of patients would undergo changes in clinical profiles during the first 24 h of hospitalization, and these changes would be associated with adverse events. We evaluated a prospective cohort of patients with clinical data available at ED presentation and 12-24 h after ED treatment for AHFS. ⋯ Patients whose clinical profile started and stayed abnormal had a significantly greater proportion of events than those who started and stayed normal (26.1% vs. 11.3%; P = 0.03). Patients with abnormal clinical profiles at presentation that remain abnormal throughout the first 12-24 h of hospitalization are at increased risk of 30-day adverse events. Future clinical trials may need to consider targeting these patients, as they may be the most likely to benefit from experimental therapy.
