Women's Heart Health and the Menopausal Transition: Two Faces of the Same Coin

The impact of the presence or absence of sex hormones on women's health is woefully underresearched. Fundamentally, women's bodies are now understood to spend considerable time under widely fluctuating hormonal influences, including puberty, pregnancy, peripartum, and menopause, and a woman's vessels are therefore preset for functional and physiological alterations based on levels of sex hormones. However, our understanding of the influences of sex hormones on the regulation of a multitude of biological and physiological processes has not translated into the development and/or collection or analyses of data on therapeutic treatments and/or outcomes in the context of women's disease management.

The Canadian Women's Heart Health Alliance ATLAS on the Epidemiology, Diagnosis, and Management of Cardiovascular Disease in Women - Chapter 9: Summary of Current Status, Challenges, Opportunities, and Recommendations

This final chapter of the Canadian Women's Heart Health Alliance "ATLAS on the Epidemiology, Diagnosis, and Management of Cardiovascular Disease in Women" presents ATLAS highlights from the perspective of current status, challenges, and opportunities in cardiovascular care for women. We conclude with 12 specific recommendations for actionable next steps to further the existing progress that has been made in addressing these knowledge gaps by tackling the remaining outstanding disparities in women's cardiovascular care, with the goal to improve outcomes for women in Canada.

Secondary Prevention and Rehabilitation for Spontaneous Coronary Artery Dissection: A Systematic Review

BACKGROUND

Spontaneous coronary artery dissection (SCAD) is a serious, noniatrogenic and nontraumatic cardiac event that predominantly affects women, with a high risk of recurrence. Secondary prevention strategies are not well understood in this population. Therefore, the aim of this systematic review is to determine the current evidence on secondary prevention strategies and their effect on recurrent cardiac events and quality of life (QOL).

METHODS

A literature search was conducted on August 21, 2021, of Ovid MEDLINE, Ovid Embase, CINAHL, Cochrane Library (via Wiley), Google Scholar, and ProQuest Dissertations & Theses Global. Literature on adult SCAD survivors who underwent secondary prevention measures with reported outcomes on major adverse cardiovascular events or QOL were included. Articles solely on pregnancy-associated SCAD or fibromuscular dysplasia were excluded.

RESULTS

Thirty studies were included in this review. A variety of research methodologies were explored. There were no randomized controlled trials. Overall, the quality of the evidence was moderate. Although evidence on secondary prevention was limited, tailored medical management was shown to have the most effect on decreasing recurrent events. Cardiac rehabilitation (CR) was supported as a safe and effective program for SCAD patients, with no reported associations with recurrent SCAD events or major adverse cardiovascular events. CR along with psychosocial interventions showed promise in improving QOL in SCAD survivors.

CONCLUSIONS

Medical management has the most effect in reducing recurrent events. CR, as a secondary prevention program, can provide interventions that might improve QOL. Randomized trial evidence on therapies for patients with SCAD are needed.

Comparing the Effectiveness of Two Cardiac Rehabilitation Exercise Therapy Programs

Cardiovascular diseases are among the leading causes of morbidity and mortality in Canada, highlighting the critical role of disease prevention and risk reduction programs. Cardiac rehabilitation (CR) is a key component of comprehensive cardiovascular care. Currently, more than 200 CR programs are established across the country, varying in duration, number of in-person supervised exercise sessions, and recommendations for exercise frequency at-home. In an increasingly cost-conscious healthcare environment, the effectiveness of healthcare services must be consistently reevaluated. This study evaluates the impact of 2 CR programs implemented by the Northern Alberta Cardiac Rehabilitation Program, by comparing peak metabolic equivalents achieved by study participants in each program. We hypothesize that our "hybrid" CR program, which is structured as an 8-week program with weekly in-person exercise sessions and a prescribed home exercise program, has patient outcomes similar to those of our "traditional" CR program, which required biweekly in-person exercise sessions over the course of 5 weeks. The results of this study may have implications for evaluating how to minimize barriers to both rehabilitation participation and long-term effectiveness of CR programs. The results may help inform the structuring and funding of future rehabilitation programs.

Participant exercise attendance in community-based, bridging, and hospital-based cardiac rehabilitation: a retrospective case control study

Background

A paucity of studies have investigated participant attendance in community-based and hybrid cardiac rehabilitation programs in the Canadian setting. We compared exercise-session attendance of community-based, bridging (hospital plus community-based), and hospital-based participants who attended a high-volume cardiac rehabilitation program in Alberta, Canada.

Methods

Exercise sessions attended and participant characteristics were collected and analyzed from 230 records of patients who attended cardiac rehabilitation between 2016 and 2019. Community-based (n = 74) and bridging (n = 41) program participants were age- and sex-matched in a 1:1 ratio to hospital-based participants. The number of exercise sessions attended was compared among program groups, between female and male patients, and for patients with vs without cardiac surgery. The percentage of exercise sessions attended was also compared among program groups.

Results

Bridging participants attended the greatest number of exercise sessions (median = 10.0 sessions) and demonstrated a significantly higher percentage of sessions attended (91%, 25th and 75th percentile interquartile range [IQR] = 64, 100%) than matched hospital participants (median = 6.0 sessions; 63%, 25, 75 IQR = 13, 94%; P = 0.01). Percentage of sessions attended did not differ for bridging and community-based participants (P = 0.30). Exercise-session attendance was similar for community-based participants (median = 6.0 sessions; 75%, 25, 75 IQR = 38%, 88%) vs their hospital matches (median = 6.0 sessions; 81%, 25, 75 IQR = 38%, 100%; P ≥ 0.37), as well as for female vs male patients (median = 7.0 sessions for both sexes; P = 0.66), and for surgical vs nonsurgical patients (median = 7.0 sessions; P = 0.48). Female patients in the bridging program attended significantly more exercise sessions in the community, compared with male patients in the bridging program (P = 0.02).

Conclusions

Bridging participants attended the most exercise sessions overall and demonstrated a higher percentage attendance than hospital-based participants. These results suggest that a hybrid program consisting of hospital and community-based exercise was favourable for exercise-session attendance. Given modern approaches to de-medicalize cardiac rehabilitation, our findings further support the provision of community program offerings, without detriment to patient session attendance.
