Determining post-test risk in a national sample of stress nuclear myocardial perfusion imaging reports: implications for natural language processing tools.
The authors investigated whether Natural Language Processing (NLP) tools could potentially help estimate myocardial perfusion imaging (MPI) risk. Subjects were VA patients who underwent stress MPI and coronary angiography 2009-11; stress test reports were randomly selected for analysis. The authors found that post-test ischemic risk was determinable but rarely reported in this sample of stress MPI reports. They conclude that this supports the potential use of NLP to help clarify risk and recommend further study of NLP in this context.

Facility-level variation in stress test utilization in veterans with ischemic heart disease.
The aim of this study was to quantify variation in cardiac stress test utilization across the Veterans Health Administration (VA) in patients with established ischemic heart disease (IHD). The investigators used VA datasets to identify adults with IHD (myocardial infarction, percutaneous coronary intervention, and/or coronary artery bypass grafting) with a primary care clinic visit at the VA in fiscal year 2014.

SCOT-HEART: does it live up to the PROMISE?
This paper examines the Scottish Computed Tomography of the Heart (SCOT-HEART) trial which was a prospective, openlabel, parallel group, multicenter trial that randomized 4146 adults (ages 18–75), referred for suspected angina to 12 cardiology clinics across Scotland between November 18, 2010 and September 24, 2014, to an initial strategy of computed tomographic Angiography (CTA) plus standard care or standard care alone in a 1:1 fashion.

The variation in recovery: role of gender on outcomes of young AMI Patients (VIRGO) classification system: a taxonomy for young women with acute myocardial infarction.
The authors developed a novel taxonomy among adults up to age 55 with acute myocardial infarction (AMI) enrolled in the Variation in Recovery: Role of Gender on Outcomes of Young AMI Patients (VIRGO) study. They found that approximately 1 in 8 young women with AMI is unclassified by the Universal Definition of MI. They proposed a more inclusive taxonomy that could serve as a framework for understanding biological disease mechanisms, therapeutic efficacy, and prognosis in this population.

Electrocardiogram in preparticipation athletic evaluations among insured youths.
The researchers retrospectively characterized electrocardiogram (ECG) use among preparticipation history and examinations (PPEs). They found that thirteen percent of PPEs with ECG and 0.5 percent of PPEs alone led to a cardiology referral. After PPEs with ECG, cardiac disease was identified in 18 percent (2 percent sports-limiting); after PPEs alone, cardiac disease was identified in 0.5 percent (0.03 percent sports-limiting).

Missed diagnoses of acute myocardial infarction in the emergency department: variation by patient and facility characteristics.
The purpose of this study is to estimate the frequency of missed heart attacks or their precursors (e.g., unstable angina) in the emergency department (ED) by examining use of EDs in the week prior to hospitalization for heart attack. This study of 111,973 patients found an overall rate of 0.9 percent for missed diagnoses of heart attacks.
