About

A feasibility study of prehospital echocardiographic examination and point-of-care troponin analysis, conducted by paramedics, in patients with suspected acute coronary syndrome. Echocardiographic images are sent together with information of TnT values and ECG signs to there cardiologist on call, deciding for immediate Cath lab (PCI) evaluation or local hospital evaluation.

Full description

Assessing the feasibility and sensitivity and specificity of prehospital risk stratification by echocardiography and Troponin T in patients with suspected acute coronary syndrome, compared with conventional in-hospital evaluation.

The trial will be conducted at Sørlandet Hospital, Norway. One acute care ambulance in Agder county will be equipped with a high-end cardiac ultrasound scanner with wireless communication to the cardiac centre/cardiologist, and a point-of-care troponin T quantitative analysis kit Paramedics will be offered a comprehensive hands-on course in cardiac ultrasound image acquisition by an echo-technician and a cardiologist. Similar, a short course will be given in point-of-care troponin analysis.

Imaging quality Communication between paramedic and cardiologist established Image transfer and interpretation by cardiologist functional Technical problems addressed and solved in collaboration with manufacturer
