Observational StudyEpicardial adipose tissue and coronary artery calcium predict incident myocardial infarction and death in HIV-infected patients.
Epicardial adipose tissue (EAT) and coronary artery calcium (CAC) have been associated with incident coronary artery disease (CAD) and all-cause mortality in the general population. Their prognostic impact in HIV is unknown. ⋯ In this observational cohort of HIV patients, EAT and CAC were independent predictors of hard outcomes after a median follow-up of approximately 3 years.

Randomized Controlled Trial Multicenter StudyComputed tomography-based high-risk coronary plaque score to predict acute coronary syndrome among patients with acute chest pain - Results from the ROMICAT II trial.
Coronary computed tomography angiography (CTA) can be used to detect and quantitatively assess high-risk plaque features. ⋯ The ROMICAT score derived from semi-automated quantitative measurements of high-risk plaque features was an independent predictor of ACS during the index hospitalization and was incremental to gender and presence of ≥ 50% stenosis.

Multicenter Study Comparative Study Observational StudySafety and efficiency of outpatient versus emergency department-based coronary CT angiography for evaluation of patients with potential ischemic chest pain.
While coronary CT angiography (coronary CTA) may be comparable to standard care in diagnosing acute coronary syndrome (ACS) in emergency department (ED) chest pain patients, it has traditionally been obtained prior to ED discharge and a strategy of delayed outpatient coronary CTA following an ED visit has not been evaluated. ⋯ In ED chest pain patients with a low risk of ACS, performing coronary CTA as an outpatient may be a safe strategy.

Comparative StudyUtility of hand-held devices in diagnosis and triage of cardiovascular emergencies. Observations during implementation of a PACS-based system in an acute aortic syndrome (AAS) network.
Prompt diagnosis and early referral to specialized centers is critical for patients presenting with cardiovascular emergencies, including acute aortic syndromes (AAS). Prior data has suggested that mobile access to imaging studies with hand-held devices can accelerate diagnosis and management. ⋯ This study demonstrates that hand-held devices can be a potential useful tool to assist in diagnosis and triage of patients presenting with cardiovascular emergencies. Further studies are needed to assess the impact of screen size and resolution.
