Changes in Cardiac Electrical Biomarker in Response to Coronary Arterial Occlusion: An Experimental Observation.

Cardiac electrical biomarker (CEB), an indicator of ischaemia-induced change in myocyte polarity, has been proposed for diagnosis of acute coronary syndrome. However, effect of coronary occlusion on CEB has not been demonstrated. CEB was acquired before (CEB0), during maximal adenosine hyperaemia (CEBhyp), balloon inflations (CEBmax) and 1 (CEB1h), 2 (CEB2h) and 3 (CEB3h) h after percutaneous coronary intervention along with pre- and post-procedural troponin-I.

ChroniSense National Early Warning Score Study (CHESS): a wearable wrist device to measure vital signs in hospitalised patients-protocol and study design.

Introduction: The National Early Warning Score is used as standard clinical practice in the UK as a track and trigger system to monitor hospitalised patients. Currently, nurses are tasked to take routine vital signs measurements and manually record these on a clinical chart. Wearable devices could provide an easier, reliable, more convenient and cost-effective method of monitoring.

Diagnostic accuracy of cardiothoracic ratio on admission chest radiography to detect left or right ventricular systolic dysfunction: a retrospective study.

Objectives: To determine the diagnostic accuracy of the cardiothoracic ratio on postero-anterior or antero-posterior chest radiographs in predicting left ventricular or right ventricular dysfunction on echocardiography in an inpatient population.

Design: Retrospective study.

Setting: Two secondary care hospitals in the United Kingdom.

The survival time of chocolates on hospital wards: covert observational study.

Objective: To quantify the consumption of chocolates in a hospital ward environment.

Design: Multicentre, prospective, covert observational study.

Setting: Four wards at three hospitals (where the authors worked) within the United Kingdom.
