Diagnostic value of the electrocardiogram in the assessment of prior myocardial infarction.

Background: The best available imaging technique for the detection of prior myocardial infarction (MI) is cardiac magnetic resonance (CMR) with late gadolinium enhancement (LGE). Although the electrocardiogram (ECG) still plays a major role in the diagnosis of prior MI, the diagnostic value of the ECG remains uncertain. This study evaluates the diagnostic value of the ECG in the assessment of prior MI.

Selecting patients with non-ST-elevation acute coronary syndrome for coronary angiography: a nationwide clinical vignette study in the Netherlands.

Objective: Cardiac guidelines recommend that the decision to perform coronary angiography (CA) in patients with Non-ST-Elevation Acute Coronary Syndrome (NST-ACS) is based on multiple factors. It is, however, unknown how cardiologists weigh these factors in their decision-making. The aim was to investigate the importance of different clinical characteristics, including information derived from risk scores, in the decision-making of Dutch cardiologists regarding performing CA in patients with suspected NST-ACS.

Negative predictive value of SPECT for the occurrence of MACE in a medium-sized clinic in the Netherlands.

Background: Single-photon emission computed tomography (SPECT) is an important prognostic tool in evaluating coronary artery disease (CAD), with a high negative predictive value (NPV) for the occurrence of major adverse cardiac events (MACE). The prognostic value of SPECT is disputed in women, patients with atrial fibrillation (AF), diabetes, left bundle branch block (LBBB) and renal impairment.

Methods: Seven hundred sixty-two patients without prior history of CAD who had SPECT without perfusion deficits were followed for 2 years for MACE.
