Brief Summary in Lay Language

This is a scientific study, in which is to be examined whether already at the emergency is past and find out with greater safety by early ultrasound examination at heart, which on the one hand are the cause of the symptoms and on the other with the presumptive diagnosis of acute coronary syndrome (Narrowed coronary arteries ) leads to faster treatment of the opening of the throat. There are two study groups, one gets the standard method and the other group will receive the early ultrasound diagnosis.

Brief Summary in Scientific Language

Can a transthoracic echocardiography (TTE), which is already performed by the emergency physician in preclinical patients with NSTEMI ACS and a regional wall motion disorder diagnosed?
Leads in patients with NSTEMI, where preclinical regional wall motion disorder is diagnosed in a shortening of the contact-to-balloon time.
Comparison standard method NSTEMI vs. TTE preclinical and in the presence of regional wall motion abnormalities transport to the cardiac catheterization

Primary Outcome

- Compliance of identified wall motion abnormalities with ischemic area in the cardiac catheterization findings
- Contact-to-balloon time with NSTEMI (Non-ST-elevation myocardial infarction)

end of 1:1-Block primary endpoint
start of 1:1-Block secondary endpoint

Secondary Outcome

- Incidence of NSTEMI ACS patients
- Pre-clinically feasible echocardiography (examination quality)
- Incidence of wall motion abnormalities in ACS patients
- Incidence of other diseases diagnosed by TTE (transthoracic Echocardiography) (pleural effusion, pulmonary embolism, aortic stenosis / insufficiency, pericardial effusion)
- 30 and 90 days in-hospital-mortality
- Hospital days, ICU days, and monitor surveillance
