Abstract MPTH62: Midlife Resistance Exercise Behaviors and Incident Heart Failure with Preserved Ejection Fraction: The Atherosclerosis Risk in Communities Study
Introduction: Heart failure (HF) with preserved ejection fraction (HFpEF) is now the predominant HF subtype, largely driven by the syndemic of physical inactivity and overweight/obesity in an aging population. Deranged skeletal muscle energetics and regional ectopic adipose depots are key cardiometabolic pathways in the pathogenesis of HFpEF, both of which may be favorably modified by 1-2 hours/week of resistance exercise (RE). However, its association with HFpEF risk has not been thoroughly examined. We investigated the association between midlife RE behaviors and incident HFpEF in the Atherosclerosis Risk in Communities (ARIC) study. Hypothesis: Participation in RE at midlife is inversely associated with the risk of incident HFpEF. Methods: Our exposure (RE)—including weightlifting and bodyweight resistance exercises—was assessed using the validated Baecke questionnaire and reported weekly RE duration was averaged across Visits 1 and 3 (1987-1995). We dichotomized averaged RE as 0 hr/wk (‘No RE’, reference) and >0 hr/wk (‘Any RE’). Our outcome (incident HFpEF) was identified through committee-adjudicated HF hospitalizations (January 1, 2005 to December 31, 2023) using medical chart abstraction. Participants with prevalent HF, death, or loss to follow-up before January 1, 2005 were excluded. We constructed Cox regression models to evaluate the association between midlife RE and incident HFpEF. Model 1 adjusted for age, sex, race, field center, education, smoking status, alcohol consumption, and non-RE physical activity. Given that adiposity may lie on the causal pathway, waist-height ratio (WHtR; both measured in cm) was added in Model 2. Results: 10,751 Black and White participants (803 incident HFpEF cases) were analyzed over a median follow-up time of 14.4 years (mean±SD Visit 1 age, 53.3±5.6 years; average Visit 1 and 3 WHtR, 0.58±0.08; 24.7% Black; 57.4% female). 1,217 participants (11.3%) reported engaging in RE at Visits 1 and/or 3, with a median duration of 0.84 hr/wk (IQR, 0.50-1.61). Compared to No RE, the fully adjusted hazard ratio (HR) for Model 1 for Any RE was: 0.78 (95% CI, 0.61-1.00, P = 0.05). The association was attenuated after adjustment for WHtR: HR = 0.84 (0.65-1.07, P = 0.16). Conclusion: Participation in RE at midlife is associated with a 22% lower risk of incident HFpEF. To inform public health and clinical guidelines, further studies are needed to clarify the role of RE in HFpEF prevention.
Unintended prolonged opioid use: a prospective case–control study
Abstract Appropriate short-term use of opioids in opioid-naive adults can result in unintended prolonged opioid use (UPOU) which is associated with significant morbidity and mortality. The objective of this prospective case–control study was to identify incident cases of UPOU and to compare their characteristics with patients who did not progress to UPOU. Opioid-naive adults receiving an initial opioid prescription for surgical or nonsurgical indications were recruited at 3 clinical sites. Patients progressing to UPOU (cases) were identified 90 days after the initial prescription and compared with patients who did not progress to UPOU (controls). The status of opioid use was verified using urine drug tests. The cohort included 513 cases and 517 controls. The mean (SD) patient age was 49.6 (15.3) years and 694 (67.4%) were female. In an adjusted logistic regression analysis, several patient characteristics significantly associated with UPOU included ≥2 emergency department evaluations in the past year; prior spine, joint replacement, or cataract surgery; status as a current or former smoker; daily use of over-the-counter pain medications; opioid craving; and greater pain interference. Conversely, characteristics negatively associated with UPOU included postsurgical pain as the indication for the initial opioid prescription, prior pregnancy, greater widespread body pain, and lower levels of general activity. The findings of this study offer novel insights into the behavioral pain responses and patient characteristics associated with UPOU. These results will be used to promote strategies to identify at-risk patients and to deploy interventions targeting the modifiable risk factors for UPOU.
