Introduction Paper I: An Artificial Neural Network (ANN) was constructed to identify ST Elevation Myocardial Infarction (STEMI) and predict the need for Percutaneous Coronary Intervention – PCI. Paper II, III and IV: Studies suggest that O2 therapy may be harmful in STEMI patients. We therefore conducted the SOCCER study to evaluate the effects of O2…
Victims of homicide and attempted homicide are not uncommon in Sweden. We therefore aimed to study these victims to understand their injuries, their cause of death, and their relationship to the offender. All cases during five years in a district court in Sweden, where an offender had been convicted for homicide or attempted homicide, were…
![Increased Use of Firearms is a Challenge for the Emergency Care [Swedish]](https://ardavan.se/wp-content/uploads/2018/07/LATI-1735-1.jpg)
Serious violent crimes continue to be a major concern in Sweden. Not least, this applies to firearm-related violent crimes which are increasing in the country.
Objectives Guidelines recommend a 0-hour/1-hour high-sensitivity cardiac troponin T (hs-cTnT) diagnostic strategy in acute chest pain patients. There are, however, little data on the performance of this strategy when combined with clinical risk stratification. We aimed to evaluate the diagnostic accuracy of an accelerated diagnostic protocol (ADP) using the 0-hour/1-hour hs-cTnT strategy together with an…
Background Although oxygen (O2 ) is routinely used in patients with acute myocardial infarction (AMI), it may have negative effects. In this substudy of the SOCCER trial, we aimed to evaluate the effects of O2 -treatment on myocardial function in patients with ST elevation myocardial infarction (STEMI). Methods Normoxic (≥94%) STEMI patients were randomized in…
Left ventricular end-diastolic mean wall thickness (LVEDMWT) can be simply estimated from left ventricular mass and left ventricular end-diastolic volume with high accuracy and precision. Estimated LVEDMWT can in turn be used to calculate thickness-to-volume ratio (TVR) as a new index of relative wall thickness. The maximum TVR found in endurance athletes was lower than…

Psychiatric diagnosis is scarce among criminal gang members, and thus differs compared to other violent offenders.
Objective Recent studies suggest that administration of O2 in patients with acute myocardial infarction may have negative effects. With the use of cardiac MRI (CMR), we evaluated the effects of supplemental O2 in patients with ST elevation myocardial infarction (STEMI) accepted for acute percutaneous coronary intervention (PCI). Materials and methods This study was a randomized-controlled…
Study objective We evaluate the diagnostic accuracy of a high-sensitivity cardiac troponin T (hs-cTnT) level less than 5 ng/L or less than or equal to 14 ng/L at emergency department (ED) presentation, combined with the emergency physician’s assessment of history and ECG, for ruling out major adverse cardiac events within 30 days. Methods This prospective…
