PPCI - it’s 24/7 or not at all? Dr JIM HALL CONSULTANT CARDIOLOGIST JAMES COOK UNIVERSITY HOSPITAL MIDDLESBROUGH
NO CONFLICT OF INTEREST TO DECLARE
PPCI Is it justifiable to have a system that includes treating STEMI patients with PPCI in some units ‘when available’ e.g. 9-5 Mon-Fri and not uniformly in a Heart Attack Centre where PPCI is available ‘all the time’ (24/7) ? S n
