Screening coronary artery disease with computed tomography angiogram should limit normal invasive coronary angiogram, regardless of pretest probability.

Backgound: Performing functional testing (FT) or a computed tomography angiogram (CCTA) before invasive coronary angiogram (ICA) is recommended for coronary artery disease (CAD). We aimed to evaluate, in a real life setting, the rate of strictly normal ICA following a positive noninvasive test result.

Methods: We included all patients who underwent an ICA with a prior positive FT or CCTA.

[Clinical aspects of acute coronary syndromes].

There are two types of acute coronary syndromes : those with or without ST-segment elevation. The former require urgent therapeutic measures to reopen the culprit artery (intravenous thrombolysis or primary percutaneous coronary intervention). For the latter, risk stratification is essential and is based upon clinical and biochemical markers.
