Three-year outcomes and cost analysis in patients receiving 64-slice computed tomographic coronary angiography for chest pain.

Sixty-four slice computed tomographic coronary angiography (CTCA) is being used more often in the evaluation of patients with chest pain. The strength of this test is its high specificity and negative predictive value in exclusion of coronary artery disease (CAD). Its use remains controversial because there are theoretical risks of radiation, additional costs of the test, and no long-term data to suggest that excluding CAD by use of this test results in positive patient outcomes.

Syndrome of protein C deficiency and anterior wall acute myocardial infarction at a young age from a single coronary occlusion with otherwise normal coronary arteries.

Findings in a 19-year-old man with anterior wall acute myocardial infarction and total occlusion of the left anterior descending coronary artery associated with protein C deficiency are described. In addition, 5 previously reported patients with similar findings are summarized.
