The role of daily adjustment disorder, depression and anxiety symptoms for the physical activity of cardiac patients.

BACKGROUND: Physical activity (PA) is crucial in the treatment of cardiac disease. There is a high prevalence of stress-response and affective disorders among cardiac patients, which might be negatively associated with their PA. This study aimed at investigating daily differential associations of International Classification of Diseases (ICD)-11 adjustment disorder, depression and anxiety symptoms with PA and sedentary behaviour (SB) during and right after inpatient cardiac rehabilitation. METHODS: The sample included N = 129 inpatients in cardiac rehabilitation, Mage = 62.2, s.d.age = 11.3, 84.5% male, n = 2845 days. Adjustment disorder, depression and anxiety symptoms were measured daily during the last 7 days of rehabilitation and for 3 weeks after discharge. Moderate-to-vigorous PA (MVPA), light PA (LPA) and SB were measured with an accelerometer. Bayesian lagged multilevel regressions including all three symptoms to obtain their unique effects were conducted. RESULTS: On days with higher adjustment disorder symptoms than usual, patients engaged in less MVPA, and more SB. Patients with overall higher depression symptoms engaged in less MVPA, less LPA and more SB. On days with higher depression symptoms than usual, there was less MVPA and LPA, and more SB. Patients with higher anxiety symptoms engaged in more LPA and less SB. CONCLUSIONS: Results highlight the necessity to screen for and treat adjustment disorder and depression symptoms during cardiac rehabilitation.

Implementation of a Novel Medication Regimen Following Cardiac Rehabilitation: an Application of the Health Action Process Approach.

BACKGROUND: Medication adherence is an indispensable prerequisite for the long-term management of many chronic diseases. However, published literature suggests that non-adherence is widely prevalent. Health behavior change theories can help understand the underlying processes and allow the accumulation of knowledge in the field. The present study applied the health action process approach (HAPA) in an intensive longitudinal research design to investigate medication adherence in patients after discharge from inpatient cardiac rehabilitation. METHOD: In total, n = 139 patients (84.9% male, Mage = 62.2 years) completed n = 2,699 daily diaries in the 22 days following discharge from inpatient cardiac rehabilitation. Patients' intentions to take medication and predictors were assessed in daily end-of-day questionnaires. Adherence to medication was measured subjectively (self-report) and objectively. Multilevel modeling was applied to disentangle the between- and within-person level. RESULTS: Higher levels of risk awareness and self-efficacy were positively associated with intentions to take medication at both levels of analysis. Contrary to theoretical assumptions, positive outcome expectations were not associated with intention, neither between- nor within-person. In contrast to published literature, patients showed very high medication adherence (95.2% self-report, 92.2% objectively). CONCLUSION: In line with the theoretical assumptions, the results showed that risk awareness and self-efficacy are promising modifiable factors that could be targeted to motivate patients to take medication as prescribed. Daily measurements revealed that patients took their medication as prescribed; thus, future studies should make every effort to recruit patients vulnerable to non-adherence to avoid ceiling effects.

Self-monitoring of oral anticoagulation: systematic review and meta-analysis of individual patient data.

BACKGROUND: Uptake of self-testing and self-management of oral anticoagulation [corrected] has remained inconsistent, despite good evidence of their effectiveness. To clarify the value of self-monitoring of oral anticoagulation, we did a meta-analysis of individual patient data addressing several important gaps in the evidence, including an estimate of the effect on time to death, first major haemorrhage, and thromboembolism. METHODS: We searched Ovid versions of Embase (1980-2009) and Medline (1966-2009), limiting searches to randomised trials with a maximally sensitive strategy. We approached all authors of included trials and requested individual patient data: primary outcomes were time to death, first major haemorrhage, and first thromboembolic event. We did prespecified subgroup analyses according to age, type of control-group care (anticoagulation-clinic care vs primary care), self-testing alone versus self-management, and sex. We analysed patients with mechanical heart valves or atrial fibrillation separately. We used a random-effect model method to calculate pooled hazard ratios and did tests for interaction and heterogeneity, and calculated a time-specific number needed to treat. FINDINGS: Of 1357 abstracts, we included 11 trials with data for 6417 participants and 12,800 person-years of follow-up. We reported a significant reduction in thromboembolic events in the self-monitoring group (hazard ratio 0·51; 95% CI 0·31-0·85) but not for major haemorrhagic events (0·88, 0·74-1·06) or death (0·82, 0·62-1·09). Participants younger than 55 years showed a striking reduction in thrombotic events (hazard ratio 0·33, 95% CI 0·17-0·66), as did participants with mechanical heart valve (0·52, 0·35-0·77). Analysis of major outcomes in the very elderly (age ≥85 years, n=99) showed no significant adverse effects of the intervention for all outcomes. INTERPRETATION: Our analysis showed that self-monitoring and self-management of oral coagulation is a safe option for suitable patients of all ages. Patients should also be offered the option to self-manage their disease with suitable health-care support as back-up.

Predicting physical activity following cardiac rehabilitation: A longitudinal observational study.

PURPOSE: The adoption of a healthy lifestyle is crucial for patients with established cardiac diseases. However, many patients do not engage in regular physical activity in their everyday life. RESEARCH METHOD: The present study applied the health action process approach (HAPA) in an intensive longitudinal research design (n = 3,354 daily surveys) investigating intention towards physical activity and objectively measured physical activity in 137 cardiac patients (Mage = 62.1 years) during and after inpatient rehabilitation across 28 days. Self-reported HAPA variables were measured daily in online questionnaires at the end of each day. Theory-driven hypotheses were tested using linear multilevel models. RESULTS: One-third of the sample did not reach the recommended physical activity levels in the first weeks after discharge from rehabilitation. Results are mostly in line with the motivational HAPA phase at both levels of analysis; outcome expectations and self-efficacy were positively associated with intentions. Results for the volitional phase were partly in line with the HAPA. Daily deviations in previous-day planning and concurrent action control were positively associated with physical activity during and after cardiac rehabilitation. CONCLUSION: The results of this study partly speak towards the HAPA in predicting physical activity in cardiac patients, thereby replicating prior research. The HAPA framework offers guidance for motivating and empowering cardiac patients to be more active in their everyday life. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Physical activity after cardiac rehabilitation: Explicit and implicit attitudinal components and ambivalence.

OBJECTIVE: Physical activity is crucial in the treatment of cardiac disease. In addition to sociocognitive theories of behavior change, attitudinal ambivalence and nonconscious factors have also been demonstrated to predict physical activity. We propose an extension to the theory of planned behavior with a dual-systems approach including explicit and implicit attitudes, and different types of attitudinal ambivalence as moderators to predict the physical activity of patients after discharge from inpatient cardiac rehabilitation. METHOD: The sample comprised N = 111 cardiac patients who provided daily diary reports of intention, cognitive, affective, and implicit attitudes for 21 days after discharge (86% male, Mage = 62, SDage = 11, n = 2,017 days). Daily moderate-to-vigorous (MVPA) and light (LPA) physical activity were measured using accelerometers. Five types of ambivalence were calculated. Analyses included Bayesian multilevel modeling. RESULTS: Patients with more positive affective attitudes and more positive implicit attitudes had a higher intention. Higher ambivalence weakened the affective attitudes-intention relationship. On days with more positive implicit attitudes than usual, intention was lower, but only when ambivalence was low. Patients with higher ambivalence engaged in less MVPA. On days with extremely low ambivalence, implicit attitudes were negatively associated with tomorrow's MVPA. Patients with more positive affective attitudes engaged in more LPA, but only when their ambivalence was very low. On days with higher ambivalence than usual, the next day's LPA was shorter. However, another type of ambivalence showed the opposite effect. CONCLUSIONS: The results emphasize the importance of affective and implicit attitudes and ambivalence for the physical activity of cardiac patients.

Improving antithrombotic management in patients with atrial fibrillation: current status and perspectives.

Despite overwhelming evidence of the benefits of risk-adjusted oral anticoagulation on stroke reduction in patients with atrial fibrillation (AF), there is still considerable undertreatment. A multidisciplinary expert group was formed to discuss issues surrounding anticoagulant treatment of patients with AF to try and achieve consensus on various aspects of the implementation of guidelines on oral anticoagulation therapy in AF. Panel members were cardiologists, hematologists, and laboratory and primary care physicians with specific expertise from Europe and the United States. One of the most important conclusions of the meeting was to enhance guideline adherence by better communication of the data showing that the benefits of stroke reduction outweigh the risk of bleeding associated with treatment with vitamin K antagonists. Management of oral anticoagulation therapy by dedicated centers, such as anticoagulation clinics, or by patient self-management may improve the quality of anticoagulation and facilitate the management of these patients and thereby further facilitate optimal antithrombotic management in patients with AF.
