    ObjectiveTo evaluate the efficacy and safety of systemic thrombolysis administered to resuscitated patients after cardiac arrest (CA) due to an acute myocardial infarction (AMI), through a study of their mortality and haemorrhagic complications.DesignWe studied a retrospective cohort of patients with ischaemic heart disease gathered from the database of the Spanish multi-centre project "Analysis of Delay in AMI" (ARIAM).SettingIntensive care (ICU) and coronary care (CCU) units of 77 Spanish hospitals.Patients And ParticipantsThe study period was from 1 January 1995 to 1 January 2000, when 22,922 patients were included in the ARIAM database register; 13,704 were diagnosed with AMI and we studied 303 of these AMI patients admitted after resuscitation for CA.Measurements And ResultsOf the 303 patients studied, 228 were male (75.25%); the mean age was 64.57 +/- 12.48 years. Systemic thrombolysis was administered to 67 patients (group I) and the remaining 236 patients were managed without this treatment (group II). The ICU/CCU mortality rate of the series was 39.93 % (121 patients); that of group I was 17.91% (12 patients) and that of group II 46.18% (109 patients) (P < 0.00001). Group I required less mechanical ventilation (group I, 42.85% vs group II, 80.76 %; P < 0.00001) and fewer cardiopulmonary resuscitation attempts (33.34% vs 60.98%, P < 0.0001). Group I also showed a lower incidence of cardiogenic shock (14.28% vs 39.01%, P < 0.0001) and anoxic encephalopathy (8.62% vs 39.89% P = 0.006). There were no fatal haemorrhagic complications in either group. Logistic regression analysis showed the administration of thrombolysis to be an independent variable that protected against mortality.ConclusionsThe administration of thrombolysis to patients with AMI who require resuscitation may be efficacious in reducing mortality and is safe, with no increase in haemorrhagic complications.
