Estenosis aórtica grave en situación crítica

there is little information about patients with severe aortic stenosis (sas) who require admission to acute care units. we studied 27 patients with sas admitted in a tertiary hospital coronary care unit. the most frequent reasons for admission were severe heart failure (42%), acute coronary syndrome (39%) and cardiac arrest (8%). at a mean follow-up of 6.5 months, 11 patients died. cumulative survival was 74±8%, 70±9%, and 62±10% at 7, 30 and 60 days, respectively. out of the 27 patients, 13 (48%) underwent surgical intervention, these patients having lower euroscore (13±11 vs. 34±18%, p=0.002) and higher survival (92±7% at 7, 30 and 60 days vs. 50±13%, 40±14% and 30±14%; p=0.002). thus, patients with sas who require hospitalization in the intensive care units constitute a very high risk population, with very high mortality, especially during the first week after admission and in patients who have not undergone surgery.
