Physician: It is sick to encourage adults to cycle without helmet [Swedish]
Emergency physician Ardavan Khoshnood reacts strongly to Lorentz Tovatts (MP) statement that there are reasons for adults not to use bicycle helmets.

High time to omit oxygen therapy in ST elevation myocardial infarction
Supplemental oxygen (O2) therapy in patients with chest pain has been a cornerstone in the treatment of suspected myocardial infarction (MI). Recent randomized controlled trials have, however, shown that supplemental O2 therapy has no positive nor negative effects on cardiovascular functions, mortality, morbidity or pain in normoxic patients with suspected MI and foremost patients with…
Pre-hospital prediction of transmural myocardial infarction and the need of acute coronary reperfusion by an artificial neural network compared to real-time prediction by a cardiac care unit physician
Our Artificial Neural Network (ANN) predicted TMI and the need of immediate reperfusion therapy with a higher sensitivity than the CCU physician on call Our ANN could thus be used as decision support in ambulances. The value would primarily be in ruling out TMI and the need of immediate reperfusion When the ANN suggests immediate…
Ischemic QRS prolongation as a biomarker of myocardial injury in STEMI patients
Background Patients with acute coronary occlusion (ACO) may not only have ischemia‐related ST‐segment changes but also changes in the QRS complex. It has recently been shown in dogs that a greater ischemic QRS prolongation (IQP) during ACO is related to lower collateral flow. This suggests that greater IQP could indicate more severe ischemia and thereby…

Nothing is More Sacred than Standing up for Academic Freedom [Swedish]
In fact, what Germund Hesslow says may sound controversial, but none of what he said has been based on his personal views, writes Ardavan Khoshnood.
A multicenter evaluation of the safety and effectiveness of a 0h/1h protocol in the assessment of emergency department chest pain patients
If a 0h/1h protocol implemented in routine care can rapidly identify a large proportion of chest pain patients suitable for early discharge, with no need for further cardiac testing, this may reduce ED and hospital crowding, objective testing, health care costs and will benefit both patients and the health care system.
A multicenter evaluation of the safety and effectiveness of a 0h/1h protocol in the assessment of emergency department chest pain patients
Background In emergency department (ED) chest pain patients, the European Society of Cardiology recommends the use of a 0h/1h high-sensitivity cardiac Troponin (hs-cTn) protocol. However, the recommendation is based on observational studies and the effects of the protocol when implemented in routine care is unknown. The aim of this study is to determine the safety…
Chest-lead STJ amplitudes using arm electrodes as Reference instead of the Wilson central terminal in smartphone ECG applications: Influence on ST-elevation myocardial infarction criteria fulfillment
Background “Smartphone 12-lead ECG” for the assessment of acute myocardial ischemia has recently been introduced. In the smartphone 12-lead ECG either the right or the left arm can be used as reference for the chest electrodes instead of the Wilson central terminal. These leads are labeled “CR leads” or “CL leads.” We aimed to compare…
Left ventricular global wall thickness is easily calculated, detects and characterizes hypertrophy, and has prognostic utility
Background Cardiovascular magnetic resonance (CMR) can be used to measure left ventricular end-diastolic volume (LVEDV) and left ventricular mass (LVM). However, there is currently no good way to measure the normality of LVM in relation to a given LVEDV. We hypothesized that a simple measure of left ventricular global wall thickness (GWT) would be accurate,…
