Long-term Outcome After Survival of a Cardiac Arrest: A Prospective Longitudinal Cohort Study.

BACKGROUND: A cardiac arrest can lead to hypoxic brain injury, which can affect all levels of functioning. OBJECTIVE: To investigate 1-year outcome and the pattern of recovery after surviving a cardiac arrest. METHODS: This was a multicenter, prospective longitudinal cohort study with 1 year of follow-up (measurements 2 weeks, 3 months, 1 year). On function level, physical/cardiac function (New York Heart Association Classification), cognition (Cognitive Log [Cog-log], Cognitive Failures Questionnaire), emotional functioning (Hospital Anxiety and Depression Scale, Impact of Event Scale), and fatigue (Fatigue Severity Scale) were assessed. In addition, level of activities (Frenchay Activities Index, FAI), participation (Community Integration Questionnaire [CIQ] and return to work), and quality of life (EuroQol 5D, EuroQol Visual Analogue Scale, SF-36, Quality of Life after Brain Injury) were measured. RESULTS: In this cohort, 141 cardiac arrest survivors were included. At 1 year, 14 (13%) survivors scored below cutoff on the Cog-log. Both anxiety and depression were present in 16 (15%) survivors, 29 (28%) experienced posttraumatic stress symptoms and 55 (52%), severe fatigue. Scores on the FAI and the CIQ were, on average, respectively 96% and 92% of the prearrest scores. Of those previously working, 41 (72%) had returned to work. Most recovery of cognitive function and quality of life occurred within the first 3 months, with further improvement on some domains of quality of life up to 12 months. CONCLUSIONS: Overall, long-term outcome in terms of activities, participation, and quality of life after cardiac arrest is reassuring. Nevertheless, fatigue is common; problems with cognition and emotions occur; and return to work can be at risk.

Early neurologically-focused follow-up after cardiac arrest improves quality of life at one year: A randomised controlled trial.

BACKGROUND: Survivors of a cardiac arrest frequently have cognitive and emotional problems and their quality of life is at risk. We developed a brief nursing intervention to detect cognitive and emotional problems, provide information and support, promote self-management, and refer them to specialised care if necessary. This study examined its effectiveness. METHODS: Multicentre randomised controlled trial with measurements at two weeks, three months and twelve months after cardiac arrest. 185 adult cardiac arrest survivors and 155 caregivers participated. Primary outcome measures were societal participation and quality of life of the survivors at one year. Secondary outcomes were the patient's cognitive functioning, emotional state, extended daily activities and return to work, and the caregiver's well-being. Data were analysed using 'intention to treat' linear mixed model analyses. RESULTS: After one year, patients in the intervention group had a significantly better quality of life on SF-36 domains Role Emotional (estimated mean differences (EMD)=16.38, p=0.006), Mental Health (EMD=6.87, p=0.003) and General Health (EMD=8.07, p=0.010), but there was no significant difference with regard to societal participation. On the secondary outcome measures, survivors scored significantly better on overall emotional state (HADS total, EMD=-3.25, p=0.002) and anxiety (HADS anxiety, EMD=-1.79, p=0.001) at one year. Furthermore, at three months more people were back at work (50% versus 21%, p=0.006). No significant differences were found for caregiver outcomes. CONCLUSION: The outcomes of cardiac arrest survivors can be improved by an intervention focused on detecting and managing the cognitive and emotional consequences of a cardiac arrest.

[Cardiac troponin]. / Cardiaal troponine.

Measurement of cardiac troponins (cTnT and cTnI), the only cardiac specific biomarkers available, is the gold standard in diagnosing acute coronary syndrome. Due to the recent introduction of more sensitive methods i.e. the high-sensitivity troponin assays, the diagnostic cut-off concentrations have very recently been established. We describe two male patients who presented at the emergency department with acute chest pain, but in whom clear evidence for a myocardial infarction in the ST segment of the EKG was lacking. Case 1 illustrates that such assays enable the earlier diagnosis of acute myocardial infarction. Case 2 shows that the diagnosis of acute myocardial infarction should be accompanied by a typical rise or fall of troponin concentrations. The latest insights into high-sensitivity cardiac troponin assays are discussed in this article. We focus specifically on sensitivity and specificity, reference values obtained from a healthy control group, and the reference change value required to detect acute myocardial infarction.
