Meta-Analysis of Antidepressant Pharmacotherapy in Patients Eligible for Cardiac Rehabilitation: ANTIDEPRESSANT AMBIVALENCE.

PURPOSE: Many patients exhibit clinically significant depression upon enrollment in cardiac rehabilitation (CR). Antidepressants are a first-line treatment option for depression, but the effectiveness of antidepressants in patients with heart disease is mixed. The purpose of this meta-analysis was to evaluate the efficacy of antidepressants for depression in patients eligible for CR. METHODS: A meta-analysis was conducted including randomized controlled trials of antidepressants from January 1990 to September 2021 that compared antidepressants with placebo. Random-effects models were used between group effect sizes (Hedges' g ). RESULTS: A total of 13 trials with predominately White (68% ± 12; n =7) male (70% ± 11) samples averaging 61 ± 5 yr compared antidepressants (1128 participants) with placebo (1079 participants). Antidepressants reduced depressive symptoms ( g = 0.17: 95% CI, 0.08-0.27), but the effect was small. Heterogeneity among study effects was low ( I2 = 6.42) and nonsignificant ( Q = 10.75, P = .46), although patients with heart failure ( gHF = 0.05: 95% CI, -0.09 to 0.18) demonstrated smaller effects compared with patients with other cardiovascular disease conditions (g non-HF = 0.22: 95% CI, 0.11-0.32) ( QB [1] = 3.97; P < .05). No study reported safety concerns associated with antidepressants. SUMMARY: The effect size of antidepressant pharmacotherapy in this population is small. No trials reported on the combined effects of exercise and pharmacotherapy. If the patient is not suicidal, CR staff may consider patient preference and refer patients for additional treatment as necessary.

Distress and Prevention Behaviors During the COVID-19 Pandemic Among College Students: the Moderating Role of Resilience.

BACKGROUND: Pandemics can generate considerable distress, which can affect prevention behaviors. Resilience may buffer the negative effects of distress on engagement in relevant prevention behaviors, which may also hold true for COVID-19 prevention behaviors. The objective of the current study was to evaluate whether resilience moderated the relationship between distress and COVID-19 prevention behaviors early in the pandemic. METHODS: Data were collected via surveys in which all students at a large midwestern university were emailed invitations beginning March 18, 2020. Surveys were completed by 5,530 individuals. In addition to demographic questions and items about COVID-19 prevention behaviors, distress was assessed using the K6 Distress Scale and resilience using the Brief Resilience Scale. Data were analyzed using moderator regression analysis. RESULTS: Resilience moderates the effects from distress to prevention behaviors, such that the relationship was stronger for individuals with higher resilience than for individuals with lower resilience. When resilience was one standard deviation below the mean, at the mean value of resilience, and when resilience was one standard deviation above the mean, there was a significant positive relationship between distress and COVID-19 prevention behaviors. However, the relationship was strongest for those with high resilience, and lowest for those with low resilience. CONCLUSIONS: In the current sample, resilience appeared to influence the strength of the relationship between distress and COVID-19 prevention behaviors. Having higher resilience may promote positive adaptation to distress, leading individuals to engage in a greater number of disease-related prevention behaviors. Future research should examine this relationship longitudinally and in relation to differing constructs of resilience.

Health Literacy, Cognitive Function, and Mortality in Patients With Heart Failure.

BACKGROUND: Health literacy has predicted mortality in heart failure. However, the role of cognitive functioning in this relationship has not been evaluated. We hypothesized that health literacy would predict all-cause mortality but that cognitive functioning would modify the relationship between health literacy and mortality in heart failure. OBJECTIVE: The aim of this study was to examine the association between health literacy, cognitive functioning, and mortality in patients with heart failure. METHODS: This secondary analysis of a larger study included 298 patients with heart failure with reduced ejection fraction (trial identifier: NCT01461629). Health literacy was evaluated using the Rapid Estimate of Adult Literacy in Medicine (REALM) and Medical Term Recognition Test (METER), and cognitive functioning was evaluated using the Modified Mini-Mental Status Examination (3MS). Cox proportional hazards regression was used with time-until-death as the dependent variable. RESULTS: After controlling for age, sex, and race, neither METER nor REALM scores predicted mortality in heart failure (Ps ≥ .37). However, 3MS predicted mortality in models using the METER (Δχ2 = 9.20, P < .01; B = -.07; hazard ratio, 0.94 [95% confidence interval, 0.89-0.98]; P < .01) and REALM (Δχ2 = 9.77, P < .01; B = -0.07; hazard ratio, 0.94 [95% confidence interval, 0.90-0.97]; P < .01). Furthermore, adding the 3MS improved model fit. CONCLUSIONS: Cognitive functioning predicted mortality in heart failure better than health literacy. Results suggest the need to further evaluate the contribution of cognitive functioning to increased risk of mortality in those with heart failure.
