Recording positive daily events significantly reduced anxiety and cut major cardiovascular events in half among elderly heart disease patients with anxiety symptoms over a 6-month period . The intervention also improved treatment adherence and psychological well-being, though the mechanism remains unclear.
A randomized controlled trial of 309 elderly patients with coronary heart disease (CHD) and anxiety symptoms tested whether systematically recording positive events could improve psychological and cardiovascular outcomes. Participants were split into an intervention group (154 patients) and a control group (155 patients). The intervention group was asked to record positive events, presumably in a structured format, while the control group received standard care. The study measured outcomes at 3 months (end of intervention) and 6 months (follow-up).
The results on anxiety were substantial. At both the 3-month and 6-month checkpoints, the intervention group had significantly lower anxiety scores on the Self-Rating Anxiety Scale compared to controls (p<0.05). This wasn't a modest reduction but represented a meaningful shift in psychological state. The intervention group also showed significantly higher scores on the Positive Psychological Capital Questionnaire, suggesting the practice strengthened resilience, optimism, and sense of agency—dimensions that extend beyond simple anxiety reduction.
The cardiovascular data were striking. The intervention group showed greater improvements in most clinical indicators including diastolic blood pressure, heart rate, and blood lipid profiles (p<0.05), though systolic blood pressure did not differ significantly between groups. Most notably, the incidence of major adverse cardiovascular events (MACE)—a composite measure typically including heart attack, stroke, and cardiac death—was dramatically lower in the intervention group. Only 12 participants in the intervention group experienced MACE compared to 36 in the control group, yielding a relative risk of 0.33 (95% confidence interval: 0.18-0.61, p=0.025). Put another way, the intervention appeared to reduce the risk of serious cardiovascular complications by roughly 67%.
Treatment compliance also improved significantly in the intervention group, measured by adherence to prescribed medications and rehabilitation behaviors (p<0.05). This is a critical finding because poor compliance is common among elderly patients and directly undermines recovery. Whether improved compliance was a direct result of better anxiety or occurred through some other pathway is not entirely clear from the study design.
If you have heart disease and anxiety: This research suggests that a low-cost, non-pharmaceutical behavioral practice may meaningfully reduce anxiety and possibly lower your risk of serious complications. The intervention appears accessible—recording positive events daily is something you could implement immediately without special equipment or expertise. Combined with standard cardiac rehabilitation, this type of practice could be worth discussing with your healthcare team.
The mechanism isn't yet established. The authors don't explain precisely why recording positive events produced these effects. It's possible the practice shifts attention toward adaptive aspects of recovery, reducing rumination about disease severity. It may strengthen motivation to take medications and follow rehabilitation protocols. Or it could influence neuroendocrine pathways that affect both mood and cardiovascular function. The study didn't measure these mechanistic pathways, so that remains speculative.
Limitations to consider: This was a single-center trial with no information about demographic diversity, baseline severity of disease, or type of positive event recording used. The control group received standard care but we don't know what "standard" included—whether it involved any psychological support or was purely medical management. The 6-month follow-up is meaningful for cardiovascular events but represents a relatively short-term perspective. The study also didn't compare positive event recording against other behavioral interventions like cognitive-behavioral therapy or meditation to see if this approach is superior or simply one option among several.
Practical application: If you're interested in trying this approach, consider keeping a simple daily log of positive events, moments of progress, or things you're grateful for. The study didn't specify the exact format, duration, or whether it was private or shared with a provider. Start by trying it for a few weeks and assess whether you notice changes in mood or motivation to stick with your treatment plan. This is a complement to, not a replacement for, prescribed medications and cardiac rehabilitation.
