RESUMO

BACKGROUND: We conducted a multicenter, prospective, observational study to describe the incidence of orthostatic hypotension (OH) and orthostatic hypertension (OHtn) and its association with symptoms at standing and outcomes in patients with heart failure (HF). METHODS AND RESULTS: 321 active standing tests were performed in 87 inpatients during admission, and 316 tests were performed in 208 outpatients during follow-up. Blood pressure (BP) was measured by an automatic device 4 times in the supine position and at 1, 3 and 5 minutes of standing. Patients were queried about symptoms of orthostatic intolerance. The incidence of OH and OHtn was similar in both groups at baseline (classical OH 11%-22%, OHtn 3%-8%, depending on definition and timing). Reproducibility of BP changes with standing was low. Up to 50% of cases with abnormal responses were asymptomatic. Symptoms were variable and occurred mainly during the first minute of standing and had a U-shaped association with BP changes. OH in outpatients with HF was associated with a higher risks of death or readmission due to HF. CONCLUSIONS: Patients with HF have variable hemodynamic responses and symptoms during repeated active standing tests. OH might identify outpatients with HF who are at risk of long-term negative outcomes.
