Coronary CT Angiography, Perfusion Imaging Effective for Evaluating Patients With Chest Pain

Clinical question: When evaluating the intermediate-risk patient with chest pain, should coronary computed tomography angiography (CCTA) be used instead of myocardial perfusion imaging (MPI)?

Background: CCTA has been shown in prior randomized controlled trials to save time and money compared to other protocols, including stress ECG, echocardiogram, and MPI. Less information is available as to whether CCTA provides a better selection of patients for cardiac catheterization compared to MPI.

Study design: Randomized, controlled, comparative effectiveness trial.

Setting: Telemetry ward of an urban medical center.

Synopsis: Four hundred patients admitted with chest pain and an intermediate, pre-test probability of coronary artery disease were randomized to either CCTA or MPI. Patients were predominantly female, were ethnically varied, and had a mean age of 57 years.

Study results showed no significant difference in rates of cardiac catheterization that did not lead to revascularization at one-year follow-up. Specifically, 7.5% of patients in the CCTA group underwent catheterization not leading to revascularization, compared to 10% in the MPI group.

One limitation of the study is that it was conducted at a single site. Furthermore, the decision to proceed to catheterization was made clinically and not based on a predefined algorithm.

Bottom line: CCTA and MPI are both acceptable choices to determine the need for invasive testing in patients admitted with chest pain.

Short Takes

Certain pulmonary emboli (PE) may not be real on CT Angiography

Reported solitary PE and subsegmental PE were both associated with a high false positive result in a retrospective reinterpretation of positive PE CT angiography reports by an expert panel.

Elective colectomy improves survival in patients with advanced ulcerative colitis

Retrospective matched cohort study shows that patients with advanced ulcerative colitis choosing elective colectomy over long-term medical therapy have improved survival, especially those aged 50 years or older.
