Moderate to Severe Left Ventricular Ejection Fraction Related to Short-term Mortality of Patients with Post-cardiac Arrest Syndrome after Out-of-Hospital Cardiac Arrest / 대한구급학회지

BACKGROUND: The aim of this study was to investigate the relationships between left ventricular ejection fraction (LVEF) and mortality and neurologic outcomes with post-cardiac arrest syndrome (PCAS) after out-of-hospital cardiac arrest (OHCA). METHODS: Patients with PCAS after OHCA admitted to the intensive care unit between January 2014 and December 2015 were analyzed retrospectively. RESULTS: total of 104 patients were enrolled in this study. The mean age was 54.4 ± 15.3 years, and 75 of the patients were male (72.1%). Arrest with a cardiac origin was found in 55 (52.9%). LVEF 55% was measured in 39 (37.5%), 18 (17.3%), and 47 (45.2%) of patients, respectively. In multivariate analysis, severe LV dysfunction (LVEF < 45%) was significantly related to 7-day mortality (odds ratio 3.02, 95% Confidence Interval 1.01-9.0, p-value 0.047). CONCLUSIONS: In this study, moderate to severe LVEF within 48 hours after return of spontaneous circulation was significantly related to 7-day short-term mortality in patients with PCAS after OHCA. Clinicians should actively treat myocardial dysfunction, and further studies are needed.

Clinical Significance of Carbon Monoxide Induced Myocardial Injury

PURPOSE: This study was performed for investigation of epidemiology, clinical characteristics, and serial value of cardiac troponin level of patients who had myocardial injury due to Carbon monoxide poisoning. METHODS: This study reviewed 98 cases of Carbon monoxide poisoning patients who visited Emergency Department from January 1, 2008 to October 31, 2013. We categorized them by two groups, one with elevation of cardiac troponin level and the other with normal level. We had comparison between two groups data using statistical analysis. RESULTS: Among 98 patients of Carbon monoxide poisoning who were admitted to hospital, 10 patients were excluded. 88 patients who were included to our study, 70 patients with normal value of Troponin, and 18 patients with elevated troponin level. Of all patients, Carbon monoxide inhalation due to suicided trial patients has more higher proportion in elevated troponin level group compared with normal group (40 (57.1%) vs 15 (83.3%), P=0.041). Furthermore, corrected QT interval, length of hospital stay, number of ICU admission, also were showed higher value in elevated troponin level group. CONCLUSION: Carbon monoxide induced myocardial injury is associated with subside trial, prolongation of correted QT interval, length of hospital stay, and number of ICU admission.
