Stay in hospital was measured as the number of days the patient stayed in the hospital after the first stent was placed until death including days spent in the hospital during return stays for treatment of complications. Early complications were defined as those occurring during the first week following stent placement.
Se evaluó la estancia hospitalaria total, que hace referencia al número de días que el paciente estuvo en el hospital a partir de la colocación del primer stent, contabilizando los reingresos por cualquier complicación hasta la fecha de su muerte.
