Background: Exercise electrocardiography in asymptomatic adults has been criticized because of relatively poor accuracy predicting future heart disease risk, but studies may have been too short. We investigated if integrated analysis of graded exercise tolerance tests (GXT) predicted long-term coronary heart disease (CHD) and all-cause mortalities among community-dwelling older adults. Methods and results: From 1972 to 1974, 1789 adult residents of a predominantly Caucasian, middle- to upper-middle-class southern California community participated in a clinical evaluation that included a GXT; 52.4% (N=939) of those who had baseline GXT were followed up to 2010-up to 36years-for vital status, CHD and all-cause mortality. Multiply adjusted hazard ratios of an abnormal graded GXT were 1.65 (95% CI 0.78-3.49) and 1.56 (95% CI 1.15-2.11) for CHD and all-cause mortality, respectively. An integrated analysis hazard ratio was calculated based on the following GXT findings: significant ST change, inability to achieve target heart rate [THR], abnormal heart rate recovery [HRR], and chronotropic incompetency [ChI]. Compared to those with 0 or 1 abnormality, participants with 2 or more positive findings had significantly higher CHD (HR 2.18) and all-cause (HR 1.92) mortalities. Participants with 3 or more positive findings showed even higher hazard ratios-CHD (HR 6.16) and all-cause (HR 2.49) mortalities. When adjusted for any of 3 Framingham risk models, the integrated electrocardiographic model correlated well with CHD and all-cause mortalities. Conclusions: An integrated analysis of electrocardiographic and non-electrocardiographic measures of GXT is useful in predicting long-term CHD and all-cause mortalities in an asymptomatic middle-aged population.

Study Design: A retrospective cohort study.Purpose: To determine whether the 11-item modified frailty index (mFI) is associated with readmission rates, complication rates, revision rates, or differences in patient-reported outcome measures (PROMs) for patients undergoing posterior cervical decompression and fusion (PCDF).Overview of Literature: mFI incorporates preexisting medical comorbidities and dependency status to determine physiological reserve. Based on previous literature, it may be used as a predictive tool for identifying postoperative clinical and surgical outcomes.Methods: Patients undergoing elective PCDF at our urban academic medical center from 2014 to 2020 were included. Patients were categorized by mFI scores (0–0.08, 0.09–0.17, 0.18–0.26, and ≥0.27). Univariate statistics compared demographics, comorbidities, and clinical/surgical outcomes. Multiple linear regression analysis evaluated the magnitude of improvement in PROMs at 1 year.Results: A total of 165 patients were included and grouped by mFI scores: 0 (n=36), 0.09 (n=62), 0.18 (n=42), and ≥0.27 (n=30). The severe frailty group (mFI ≥0.27) was significantly more likely to be diabetic (<i>p</i> <0.001) and have a greater Elixhauser comorbidity index (<i>p</i> =0.001). They also had worse baseline Physical Component Score-12 (PCS-12) (<i>p</i> =0.011) and modified Japanese Orthopaedic Association (mJOA) (<i>p</i> =0.012) scores and worse 1-year postoperative PCS-12 (<i>p</i> =0.008) and mJOA (<i>p</i> =0.001) scores. On regression analysis, an mFI score of 0.18 was an independent predictor of greater improvement in ΔVisual Analog Scale neck (<i>β</i> =−2.26, <i>p</i> =0.022) and ΔVAS arm (<i>β</i> =−1.76, <i>p</i> =0.042). Regardless of frailty status, patients had similar 90-day readmission rates (<i>p</i> =0.752), complication rates (<i>p</i> =0.223), and revision rates (<i>p</i> =0.814), but patients with severe frailty were more likely to have longer hospital length of stay (<i>p</i> =0.006) and require non-home discharge (<i>p</i> <0.001).Conclusions: Similar improvements across most PROMs can be expected irrespective of the frailty status of patients undergoing PCDF. Complication rates, 90-day readmission rates, and revision rates are not significantly different when stratified by frailty status. However, patients with severe frailty are more likely to have longer hospital stays and require non-home discharge.
