RESUMEN

In a large screening program of asymptomatic middle-aged individuals, we sought to assess the degree of risk reclassification provided by comparing multiethnic study on subclinical atherosclerosis coronary artery calcium scoring (CACS) versus atherosclerotic cardiovascular disease (ASCVD) and Reynolds risk score (RRS) score. All 5,324 consecutive patients (aged 57 ± 8 years, 76% male) who underwent CACS screening at the Cleveland Clinic as part of a primary prevention executive health between March 16 and October 21 were included. The 10-year ASCVD, RRS, and multiethnic study on subclinical atherosclerosis CACS (MESA-CACS) risk scores were calculated and categorized as <1, 1 to 4.99, 5 to 9.99, and ≥10%. Compared with ASCVD, using MESA-CACS resulted in a downgraded risk in 1,667 subjects (31%), whereas 738 (14%) had an upgrade in risk (total of 45% reclassification). Similarly, compared with RRS, using MESA-CACS resulted in an upgraded risk in 797 (15%) and a downgrade in 1,380 (26%) subjects (total of 41% reclassification). However, by further dividing by the distribution of the coronary calcification, ASCVD overestimates the risk only for patients with coronary artery calcium (CAC) in 0 or 1 coronary artery only, whereas MESA-CACS overestimates if the CAC was noted in ≥2 arteries. Similarly, RRS only overestimates the risk for patients with 0 CAC, whereas it underestimates the risk for patients with any CAC. In conclusion, the use of MESA-CACS, along with CAC distribution in primary prevention clinics, results in differential and significant reclassification of traditional scores when calculating the 10-years coronary vascular disease risk. Overall, RRS underestimates and ASCVD overestimates the cardiovascular disease risk compared with MESA-CACS.

RESUMEN

BACKGROUND: In a primary prevention screening program of asymptomatic middle-aged subjects, we sought to assess the degree of risk-reclassification provided by traditional risk assessment vs. coronary artery calcification scoring (CACS). METHODS: A total of 1,806 consecutive asymptomatic subjects (age 55 years, 76% men), who underwent comprehensive screening in a primary prevention clinic between 3/2016 and 9/2017 were included. Standard risk factors, C-reactive protein (CRP) and CAC scoring were performed. % 10-year coronary heart disease (CHD) risk was calculated using Reynolds Risk Score (RRS), atherosclerotic cardiovascular disease (ASCVD) score and multiethnic study on subclinical atherosclerosis (MESA) CACS were calculated. % 10-year CHD risk for all scores was categorized as follows: <1%, 1-5%, 6-10% and >10%. RESULTS: Mean CRP, RRS, ASCVD and MESA-CACS were 2.1±4.2, 3.7±4, 4.9±6, 4.9±5; 54% had CAC of 0, while 21% had CAC >75th percentile. There was a significant, but modest correlation between MESA-CAC score and (I) RRS (r=0.62) and (II) ASCVD scores (r=0.65, both P<0.001). Compared to MESA-CAC, for RRS, (I) 188 (10%) patients had a downgrade in risk and (II) 538 (30%) patients had an upgrade in risk (40% reclassification of risk). Similarly, compared to MESA-CAC, for ASCVD score, (I) 412 (23%) patients had a downgrade in risk and (II) 329 (18%) patients had a downgrade in risk (41% reclassification of risk). CONCLUSIONS: In a primary prevention screening program of asymptomatic middle-aged patients, RRS overestimates and ASCVHD underestimates 10-year CHD risk vs. MESA-CACS. Addition of CACS results in significant risk reclassification.

RESUMEN

In primary prevention, addition of C-reactive protein and family history to standard risk factor assessment (Reynolds Risk Score or RRS) provides superior risk stratification for future cardiovascular (CV) events. We sought to assess whether addition of functional capacity to RRS provided incremental prognostic value. This was a prospective observational cohort study of 3,964 consecutive asymptomatic adults without documented CV disease (mean age 51 years, 78% men) evaluated between 2005 and 2013, who underwent clinical and treadmill stress testing at baseline. RRS was calculated; % age-gender predicted metabolic equivalents (AGP-METs) achieved and heart rate recovery (HRR) were recorded. End point was death and myocardial infarction. Findings were tested in derivation (n = 1,982) and validation samples (n = 1,982). Mean RRS and C-reactive protein were 3.7 ± 4 and 2 ± 4 mg/dl. Nine percent had family history of premature CV disease. %AGP-METs achieved, and HRR were 113 ± 20 and 24 ± 8 beats/min. Forty-six percent achieved <110% AGP-METs, whereas 41% had RRS ≥3. At 7.3 ± 3 years, there were 83 (2%) events (39 in derivation and 44 in validation samples). In derivation group, on multivariable survival analysis, higher RRS (Hazard ratio or HR 1.27 [1.07 to 1.39]), lower % AGP METs (HR 1.21 [1.09 to 1.34]) achieved and abnormal (<12 beats/min) HRR (HR 1.15 [1.02 to 1.23]) were associated with increased longer-term events (all p <0.01). Findings were similar in validation group. Cutoffs of RRS >3 and %AGP-METs <110 were associated with increased longer-term events on spline analysis in the derivation group. The continuous net reclassification improvement for longer-term events, when %AGP-METs was added to RRS was 0.79 (95% confidence interval 0.52 to 1.05; p <0.01). Findings were confirmed in validation group. In conclusion, in primary prevention, addition of exercise capacity to RRS (incorporating traditional risk factors, family history, and inflammation) provides incremental prognostic value.

RESUMEN

BACKGROUND AND OBJECTIVE: To report clinical feasibility of non-mydriatic ultra-widefield (NMUWF) imaging and determine the prevalence of peripheral retinal pathology in comparison to standard single-field imaging in a primary care setting. PATIENTS AND METHODS: Six hundred and thirty-two subjects (1,260 eyes) who underwent NMUWF imaging during annual health screening from October 2015 through March 2016 were retrospectively identified. An automated algorithm processed the raw images into: (1) NMUWF image with mask/grid outline that delineates the center 45° field simulating standard single-field photograph and (2) single-field image comprising 45° posterior pole extracted from the corresponding NMUWF image. RESULTS: Mean age of patients was 59.6 years ± 7.5 years. Of the 1,260 eyes, 1,238 eyes (98.3%) were considered optimum for grading. NMUWF images detected peripheral retinal pathology in 228 eyes (18.4%) that were not visible on corresponding single-field images. CONCLUSIONS: NMUWF imaging is feasible in a primary care setting, allows improved visualization of peripheral retinal pathology, and may therefore be useful for telemedicine screening.

RESUMEN

BACKGROUND AND OBJECTIVE: To determine the accuracy and sensitivity of a single-field non-mydriatic digital fundus image interpreted by an ophthalmologist and performed within a primary care setting. PATIENTS AND METHODS: Fundus photography using a digital non-mydriatic camera was performed on both eyes of 1,175 consecutive patients as part of an executive health program. All fundus images included a 45° field of the posterior pole capturing the optic nerve and macular area. Diagnostic findings were recorded and appropriate recommendations for follow-up were made. Patients were then contacted to see whether appropriate follow-up was successfully completed and chart reviews were performed to determine biomicroscopic findings. RESULTS: Photographs were adequate in both eyes in 1,117 patients (95.1%). Examination findings were normal in both eyes in 951 (85.1%) patients. Abnormal findings were noted in either eye in 166 (14.9%) patients. The most common abnormal findings were macular degeneration (57/166, 34.3%), optic nerve cupping (45/166, 27.1%), hypertensive retinopathy (15/166, 9.0%), and choroidal nevi (10/166, 6.0%). In all patients with abnormal findings, routine follow-up ophthalmologic examination with an eye care specialist was indicated and none of the patients required urgent attention. Sensitivity was found to be 87% and stratification was performed based on the initial diagnosis. False-positive results were from confounding diagnoses rather than true false-positives. CONCLUSION: Single-field non-mydriatic fundus photography is accurate and sensitive for screening retinal disease in a primary care setting.

RESUMEN

The measurement of blood pressure in the physician's office is subject to a number of observer errors and also to the "white-coat effect." Automatic devices that measure blood pressure without a human observer in the room can eliminate many of these problems. We argue for greater use of these devices in the physician's office.

RESUMEN

PURPOSE: The authors performed a pilot randomized controlled trial of total-body screening to assess the feasibility of a full-scale study. MATERIALS AND METHODS: After informed consent, 50 asymptomatic people were randomized to either the intervention arm (total-body screening with multidetector computed tomography) or the control arm (no screening for 3 years). The study was approved by our institutional review board and was compliant with the Health Insurance Portability and Accountability Act. Images were interpreted independently by 6 radiologists from 2 institutions. Subjects in both study arms completed periodic health questionnaires and medical utilization forms over 2 years. Key outcome variables were the incidence of symptomatic disease, medical costs, and patient-reported health. RESULTS: Sixteen screened subjects (64%) had abnormal findings on screening. A second interpretation of the images yielded a similar overall rate but with considerable variability at the subject level. No cancers were detected. Ninety percent of subjects were compliant at 2 years. Medical costs were twice as high for screened subjects, with considerable between-subject variability. Screened subjects reported fewer physical limitations than unscreened subjects. CONCLUSION: A full-scale randomized controlled trial of total-body screening will need to account for the large interreader variability in interpreting the images, the high rate of incidental findings, and the low prevalence of cancers. A full-scale study using mortality as the endpoint does not seem feasible at this time.
