Abstract Aims Coronary CT angiography (CCTA) is a first-line modality in the investigation of suspected coronary artery disease (CAD). Mapping of perivascular Fat Attenuation Index (FAI) on routine CCTA enables the non-invasive detection of coronary artery inflammation by quantifying spatial changes in perivascular fat composition. We now report the performance of a new medical device, CaRi-Heart®, which integrates standardised FAI mapping together with clinical risk factors and plaque metrics to provide individualised cardiovascular risk prediction. Methods and Results The study included 3912 consecutive patients undergoing CCTA as part of clinical care in the United States (n = 2040) and Europe (n = 1872). These cohorts were used to generate age-specific nomograms and percentile curves as reference maps for the standardised interpretation of FAI. The first output of CaRi-Heart® is the FAI-Score of each coronary artery, which provides a measure of coronary inflammation adjusted for technical, biological and anatomical characteristics. FAI-Score is then incorporated into a risk prediction algorithm together with clinical risk factors and CCTA-derived coronary plaque metrics to generate the CaRi-Heart® Risk that predicts the likelihood of a fatal cardiac event at 8 years. CaRi-Heart® Risk was trained in the US population and its performance was validated externally in the European population. It improved risk discrimination over a clinical risk factor-based model (Δ[C-statistic] of 0.085, P = 0.01 in the US Cohort and 0.149, P < 0.001 in the European cohort) and had a consistent net clinical benefit on decision curve analysis above a baseline traditional risk factor-based model across the spectrum of cardiac risk. Conclusion CaRi-Heart® reliably improves cardiovascular risk prediction by incorporating traditional cardiovascular risk factors along with comprehensive CCTA coronary plaque and perivascular adipose tissue phenotyping. This integration advances the prognostic utility of CCTA for individual patients and paves the way for its use as a screening tool among patients referred for CCTA. Translational Perspective Mapping of perivascular Fat Attenuation Index (FAI) on coronary computed tomography angiography (CCTA) enables the non-invasive detection of coronary artery inflammation by quantifying spatial changes in perivascular fat composition. We now report the performance of a new medical device, CaRi-Heart®, which integrates standardised FAI mapping together with clinical risk factors and plaque metrics to provide age-standardised reference maps and individualised cardiovascular risk prediction. This integration advances the prognostic value of CCTA and paves the way for its use as a screening tool among patients referred for CCTA.

BACKGROUND: Although it is well known that pressure ulcers are associated with negative patient outcomes and increased hospital cost, there is little research related to pressure ulcers in an intensive care unit population. OBJECTIVE: To determine the relative contribution of risk factors in the development of pressure ulcers in intensive care unit patients. METHOD: In an exploratory descriptive design, a convenience sample of 85 adults was used. Patients were enrolled in the study within 24 hours of admission to the intensive care unit; data were collected every other day until discharge from the intensive care unit. Instruments included a demographic data form, Braden Scale for Predicting Pressure Sore Risk, Skin Assessment Tool, and Decubitus Ulcer Potential Analyzer. RESULTS: The most common reasons for admission to the intensive care unit included multiple trauma from motor vehicle accidents, gunshot and stab wounds, and gastrointestinal bleeding. A pressure ulcer developed in 48 subjects. There were no significant differences in age, gender, history of diabetes or smoking, or medical diagnoses between patients in whom a pressure ulcer developed and those in whom it did not. Data analysis indicated that a Braden Scale score of 11, rather than the recommended score of 16, was statistically significant for predicting pressure ulcer risk. CONCLUSIONS: The results suggest that a cut-off score on the Braden Scale could be specific to an intensive care unit trauma population.
