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…

The West’s Role in the Shah’s Overthrow

On January 16, 1979, Shah Mohammed Reza Pahlavi, who had ruled Iran for nearly thirty-eight years, left the country in the face of a nationwide popular revolution—never to return. Shortly after his departure, it became known that the deposed monarch suffered from advanced cancer, and on July 27, 1980, he passed away in Cairo, at…

Firearm-Related Violence in Sweden – A Systematic Review

Firearm-Related Violence in Sweden – A Systematic Review

Recent reports state that firearm-related violence is increasing in Sweden. In order to understand the trend of firearm-related violence in Sweden with regard to rate, modus operandi (MO) and homicide typology, and for which injuries and causes of death firearm-related violence is responsible, a systematic literature review was conducted. After a thorough search in different…

The firearm related violence is increasing [Swedish]

The firearm related violence is increasing [Swedish]

The debate about crime statistics and which crimes are increasing and not is often infected. The discussion benefits neither from understatements nor exaggerations, but should be kept factual. The truth is that yes, some crimes are decreasing and Sweden is very safe internationally. But there are also dark clouds, for example when it comes to…

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

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,…

Diagnostic Accuracy of the Electrocardiographic Decision Support – Myocardial Ischaemia (EDS-MI) Algorithm in Detection of Acute Coronary Occlusion

Diagnostic Accuracy of the Electrocardiographic Decision Support – Myocardial Ischaemia (EDS-MI) Algorithm in Detection of Acute Coronary Occlusion

Electrocardiographic Decision Support – Myocardial Ischaemia (EDS-MI) is a graphical decision support for detection and localization of acute transmural ischaemia. A recent study indicated that EDS-MI performs well for detection of acute transmural ischaemia. However, its performance has not been tested in patients with non-ischaemic ST-deviation. We aimed to optimize the diagnostic accuracy of EDS-MI…

Effects of supplemental oxygen therapy in patients with suspected acute myocardial infarction: A meta-analysis of randomized clinical trials

Effects of supplemental oxygen therapy in patients with suspected acute myocardial infarction: A meta-analysis of randomized clinical trials

Background Although oxygen therapy has been used for over a century in the management of patients with suspected acute myocardial infarction (AMI), recent studies have raised concerns around the efficacy and safety of supplemental oxygen in normoxaemic patients. Objective To synthesise the evidence from randomised controlled trials (RCTs) that investigated the effects of supplemental oxygen…
