Introduction: Valvular heart disease (VHD) poses a growing global burden, particularly in aging populations. While transcatheter interventions have expanded rapidly over the past two decades, the extent to which trial populations reflect real-world demographics—especially age and sex—is unclear. Understanding enrollment trends and representation gaps is essential to ensure equitable, generalizable evidence for clinical decision-making. Methods: We systematically reviewed VHD interventional trials (2000–2024) indexed in PubMed. Surgical and percutaneous trials across aortic, mitral, tricuspid, and pulmonic valves were included. Trial characteristics, demographics, and interventions were analyzed using descriptive and nonparametric statistics. Results: We included 487 trials enrolling 87,412 participants (45% women). Median trial size increased over time (z = 4.98, p < 0.01), and the mean age of participants also rose significantly (z = 10.08, p < 0.01). Trials involving percutaneous (11% to 45%), bioprosthetic (22% to 53%), aortic valve (27% to 62%), and multinational (2% to 16%) interventions increased over time. Older participants were more commonly enrolled in percutaneous, industry-funded, multinational, bioprosthetic, and aortic valve trials. Female representation remained unchanged across time (median 47%, z = -0.48, p = 0.63), but trials enrolling older participants tended to include more women (ρ = 0.196, p < 0.01). Female representation was highest in mitral (59%) and tricuspid (59%) valve trials, and more common in percutaneous (52%) than surgical (42%) interventions. Conclusion: Over the past two decades, VHD trials have expanded in size and geographic scope, with increased enrollment of older adults, particularly in percutaneous and industry-sponsored studies. However, sex disparities and demographic variability persist. Future trials should prioritize inclusive designs to ensure equitable, generalizable evidence for evolving valve interventions.

Importance Cardiovascular (CV) disease is the leading cause of death globally for both men and women, yet women remain historically underrepresented in CV clinical trials, despite facing a disproportionately high burden of morbidity and mortality in many forms of CV disease. Objective To determine the representation of women across a broad range of CV trials. Evidence Review The participation of women in CV trials registered on ClinicalTrials.gov from 2017 to 2023 was systematically determined through the extraction of publicly available information. Data were extracted to identify the country of study, disease type, trial size, clinical intervention, and age of the participants. The proportion of women and the ratio of number of female to male participants (F:M ratio) were calculated for each trial. The women’s participation:prevalence ratio (PPR) was estimated for each trial based on the relative prevalence of the disease by sex in the specified region. Findings A total of 1079 registered CV trials were identified, including 1 396 104 participants, of whom 571 641 (41.0%) were women. The F:M ratio was significantly lower for studies on arrhythmia (median [IQR], 0.5), coronary heart disease (median [IQR], 0.39 [0.33-0.70]), acute coronary syndrome (median [IQR], 0.32 [0.24-0.51]), and heart failure (median [IQR], 0.51 [0.32-0.87]) but higher for obesity (median [IQR], 1.44 [1.08-4.50]) and pulmonary hypertension (median [IQR], 2.86 [1.50-3.97]) trials. The F:M ratio was higher for trials on lifestyle interventions (median [IQR], 1.51 [0.77-3.24]) than for drug trials. PPRs were low for clinical trials on coronary heart disease (median [IQR], 0.66 [0.50-0.86]), acute coronary syndrome (median [IQR], 0.79 [0.51-0.87]), and stroke (median [IQR], 0.74 [0.61-0.95]). Representation of women in CV trials varied by disease state, region, intervention, and sponsor type. Conclusions and Relevance These findings highlight both progress and persistent challenges in representation of women within CV trials. These gaps not only limit the generalizability of trial outcomes but also perpetuate inequities in evidence-based care for women with CV conditions.

Abstract Aim The cardiovascular benefits provided by glucagon‐like peptide‐1 receptor agonists (GLP‐1RAs) extend beyond weight reduction and glycaemic control. One possible mechanism may relate to blood pressure (BP) reduction. We aim to quantify the BP‐lowering effects of GLP1‐RAs. Methods A comprehensive database search for placebo‐controlled randomized controlled trials on GLP‐1RA treatment was conducted until December 2023. Data extraction and quality assessment were carried out, employing a robust statistical analysis using a random effects model to determine outcomes with a mean difference (MD) in mmHg and 95% confidence intervals (CIs). The primary endpoint was the mean difference in systolic BP (SBP) and diastolic BP. Subgroup analyses and meta‐regressions were done to account for covariates. Results Compared with placebo, GLP‐1RAs modestly reduced SBP [semaglutide: MD −3.40 (95% CI −4.22 to −2.59, p < .001); liraglutide: MD −2.61 (95% CI −3.48 to −1.74, p < .001); dulaglutide: MD −1.46 (95% CI −2.20 to −0.72, p < .001); and exenatide: MD −3.36 (95% CI −3.63 to −3.10, p < .001)]. This benefit consistently increased with longer treatment durations. Diastolic BP reduction was only significant in the exenatide group [MD −0.94 (95% CI −1.78 to −0.1), p = .03]. Among semaglutide cohorts, mean changes in glycated haemoglobin and mean changes in body mass index were directly associated with SBP reduction. Conclusion Patients on GLP‐1RA experienced modest SBP lowering compared with placebo. This observed effect was associated with weight/body mass index reduction and better glycaemic control, which suggests that BP‐lowering is an indirect effect of GLP‐1RA and unlikely to be responsible for the benefits.

Heart failure (HF) is a chronic, debilitating condition associated with significant morbidity, mortality, and socioeconomic burden. Patients with end-stage HF (ESHF) who are not a candidate for advanced therapies will continue to progress despite standard medical therapy. Thus, the focus of care shifts from prolonging life to controlling symptoms and improving quality of life through palliative care ( PC). Because the condition and prognosis of HF patients evolve and can rapidly deteriorate, it is imperative to begin the discussion on end-of-life (EOL) issues early during HF management. These include the completion of an advance directive, do-not-resuscitate orders, and policies on device therapy and discontinuation as part of advance care planning (ACP). ESHF patients who do not have indications for advanced therapies or those who wish not to have a left ventricular assist device (LVAD) or heart transplant (HT) often experience high symptom burden despite adequate medical management. The proper identification and assessment of symptoms such as pain, dyspnea, nausea, depression, and anxiety are essential to the management of ESHF and may be underdiagnosed and undertreated. Psychological support and spiritual care are also crucial to improving the quality of life during EOL. Caregivers of ESHF patients must also be provided supportive care to prevent compassion fatigue and improve resilience in patient care. In this narrative review, we compare the international guidelines and provide an overview of end-of-life and palliative care for patients with ESHF.
