RESUMEN
BACKGROUND: Conventionally, in the pre-percutaneous intervention era, free wall rupture is reported to be a major concern for using steroids in myocardial infarction (MI) patients. Therefore, the aim of this study was to evaluate the safety of the use of steroids in critically ill post-MI patients in terms of hospital course and short-term (up to 180-day) mortality. METHODS: We included patients admitted to CCU diagnosed with MI, undergone revascularization, critically ill, and requiring mechanical ventilator (MV) support. The hospital course and short-term (up to 180-day) mortality were independently compared between steroid and non-steroid cohorts and propensity-matched non-steroid cohorts. RESULTS: A total of 312 patients were included, out of which steroids were used in 93 (29.8%) patients during their management. On periodic bedside echocardiography, no free wall rupture was documented in the steroid or non-steroid cohort. When compared steroids with a propensity-matched non-steroid cohort, MV duration >24 h was 66.7% vs. 59.1%; p = 0.288, major bleeding was 6.5% vs. 3.2%; p = 0.305, need for renal replacement therapy was 9.7% vs. 8.6%; p = 0.799, in-hospital mortality was 35.5% vs. 23.7%; p = 0.077, and 180-day mortality was 48.4% vs. 41.9%; p = 0.377, respectively. The hazard ratio was 1.22 [95% CI: 0.80 to 1.88] compared to the propensity-matched non-steroid cohort. The ejection fraction (%) was found to be the independent predictor of 180-day mortality with an adjusted odds ratio of 0.92 [95% CI: 0.86 to 0.98]. CONCLUSIONS: In conclusion, using steroids is safe in post-MI patients with no significant increase in short-term mortality risk.

BACKGROUND: This clinical audit aims to evaluate the clinical data regarding the management and outcomes of acute myocardial infarction (AMI) patients requiring mechanical ventilator (MV) support, along with identifying factors associated with prolonged MV support and 180-day mortality. MATERIALS AND METHODS: In this study, we audited clinical data regarding management, in-hospital and short-term outcomes of adult patients with AMI required MV support. Patients with prolonged MV duration (>24h) and/or 180-day mortality were compared with their counterparts, and associated factors were identified. The binary logistic and Cox regression analyses were performed to determine the predictors of prolonged MV duration and 180-day mortality. RESULTS: In a sample of 312 patients, 72.8% were male, and the mean age was 60.3±11.5 years. The median MV duration was 24 [24-48] hours, with 48.7% prolonged MV duration. The admission albumin level was found to be the independent predictor of prolonged MV duration with an adjusted OR of 0.42 [0.22-0.82]. Overall 7.4% were re-intubated, 6.7% needed renal replacement therapy, 17.6% required intra-aortic balloon pump (IABP) placement, and 16.7% required temporary pacemaker placement. The survival rate was 80.4% at the time of hospital discharge, 74.7% at 30-day, 71.2% at 90-day, and 68.6% at 180-day follow-up. Age, prolonged MV duration, and ejection fraction were found to be the independent predictors of cumulative 180-day mortality with adjusted HR of 1.04 [1.02-1.07], 1.02 [1.01-1.03], and 0.95 [0.92-0.98], respectively. CONCLUSIONS: Prolonged ventilator duration has significant prognostic implications; hence, tailored early recognition of high-risk patients needing more aggressive care can improve the outcomes.
