Background: Acute decompensated heart failure (ADHF) patients with symptomatic congestion often require in-hospital admission for intravenous (IV) diuretic, impacting both patient well-being and healthcare expenses. Subcutaneous (SC) furosemide has a potential to facilitate outpatient management of ADHF patients. Thus, this study aims to assess the efficacy and safety of SC furosemide utilization, offering a potential alternative to traditional IV administration.

Methods: A systematic search was conducted until April 14 2024 across scientific databases. This review included studies comparing SC furosemide with oral and IV formulations in adult HF patients.

Results: This study analyzed 687 patients from 20 studies. The results demonstrate that SC furosemide can effectively manage symptomatic congestion in HF patients and results in significant cost reductions, symptom relief, and improved quality of life. Although further investigation into mortality rates is needed, SC furosemide demonstrates efficacy comparable to IV furosemide in diuresis and weight loss, with similar bioavailability and natriuretic effects. Adverse events are generally minor, predominantly related to skin irritation. Innovative strategies, such as developing isotonic alkaline solutions and improved infusion devices, are being explored to address these challenges.

Conclusion: SC furosemide offers a promising alternative for managing ADHF, particularly in symptomatic HF patients with volume overload. The integration of SC furosemide into routine clinical practice and future guidelines, could optimize the management of HF, reducing hospital admission and improving patient outcomes.

Purpose of review: Pulmonary embolism (PE) is the third most common cause of cardiovascular morbidity and mortality. The goal of this review is to discuss the most up-to-date literature on epidemiology, diagnosis, risk stratification, and management of acute PE.

Recent findings: Despite an increase in annual incidence rate of PE in the United States and development of multiple advanced therapies for treatment of acute PE, PE-related mortality is not consistently decreasing across populations. Although multiple risk stratification schemes have been developed, it is still unclear which advanced therapy should be used for the individual patient and optimal timing. Fortunately, multiple randomized clinical trials are underway to answer these questions. Nevertheless, up to 50% of patients have persistent reduced quality of life 6 months after acute PE, termed post-PE syndrome. Despite advances in therapeutic options for management of acute PE, many questions remain unanswered, including optimal risk stratification and management of acute PE.

Purpose of review: Body fat distribution plays a significant role in the cardiometabolic consequences of obesity. We review the impact of visceral and hepatic fat and highlight important interventions.

Recent findings: Several epidemiologic studies have established a clear association between visceral fat and cardiovascular disease. The association between hepatic fat and cardiovascular disease is less clear with discordant results. Novel evidence demonstrates sodium glucose co-transporter-2 (SGLT2) inhibitors facilitate modest weight loss and reductions in ectopic fat depots in patient with type 2 diabetes. Glucagon-like peptide-1 (GLP-1) receptor agonists have been associated with decreased visceral/hepatic fat and reductions in MACE in populations with type 2 diabetes and with overweight/obesity. Clear associations between visceral fat and cardiometabolic outcomes have been established, whereas the impact of hepatic fat remains less clear. Lifestyle modification and pharmacologic interventions remain the initial therapies, while surgical intervention is associated with improved long-term outcomes. Emerging therapies have demonstrated a profound impact on body fat distribution and cardiometabolic risk.

Purpose of review: This review aims to explore recent advances in single-cell omics techniques as applied to various regions of the human heart, illuminating cellular diversity, regulatory networks, and disease mechanisms. We examine the contributions of single-cell transcriptomics, genomics, proteomics, epigenomics, and spatial transcriptomics in unraveling the complexity of cardiac tissues.

Recent findings: Recent strides in single-cell omics technologies have revolutionized our understanding of the heart's cellular composition, cell type heterogeneity, and molecular dynamics. These advancements have elucidated pathological conditions as well as the cellular landscape in heart development. We highlight emerging applications of integrated single-cell omics, particularly for cardiac regeneration, disease modeling, and precision medicine, and emphasize the transformative potential of these technologies to advance cardiovascular research and clinical practice.

Purpose of review: Peripheral artery disease (PAD) is a growing global epidemic. Women with PAD are at elevated risk of experiencing psychosocial stressors that influence the diagnosis, management, and course of their illness due to unique sex- and gender-based factors.

Recent findings: We review existing evidence for increased psychosocial risk in women with PAD with a focus on mood disorders, chronic stress, pain experiences, substance use disorders, health behaviors and illness perceptions, and healthcare access. We discuss how these factors exacerbate PAD symptomatology and lead to adverse outcomes. Existing gaps in women's vascular care are reviewed and potential solutions to bridge these gaps through psychosocial care integration are proposed. Current care paradigms for women's vascular care do not adequately screen for and address psychosocial comorbidities. Clinician education, integration of evidence-based psychological care strategies, implementation of workflows for the management of individuals with PAD and mental health comorbidities, reform to reimbursement structures, and further advocacy are needed in this space. This review provides a construct for integrated behavioral health care for women with PAD and advocates for further integration of care.

Purpose of review: Ventricular arrhythmias (VAs) affect many patients with heart failure and underlying structural heart disease and are associated with significant morbidity and mortality. Antiarrhythmic drugs are often the initial treatment, but medication alone often fails to sufficiently suppress VAs. While catheter ablation (CA) remains the gold standard for treatment of VAs, CA is an invasive procedure and can be associated with periprocedural complications including acute clinical decompensation. Thus, there is an important need for alternative therapies.

Recent findings: Recent advances in risk stratification and the development of new ablation technologies may reduce some of the periprocedural complications and limitations of CA. In addition, less invasive therapies for VAs may provide an alternative treatment strategy for patients in both the acute and chronic setting. For patients acutely admitted with ventricular tachycardia electrical storm (VT-ES) or recurrent VT and cardiogenic shock, risk stratification tools have been developed to identify patients at high risk of acute hemodynamic decompensation during CA. These patients require a multidisciplinary approach and might need mechanical circulatory support (MCS) if CA is selected as the treatment strategy. Alternatively, less invasive therapies targeting the autonomic nervous system may be reasonable. In the chronic setting, developments in medical therapy have reduced the risk of sudden cardiac death in heart failure patients and stereotactic whole-body radiation (SBRT) has evolved as a potential, non-invasive therapy. Further research is needed to personalize VA therapy for individual patients.

Purpose of review: While primary prevention strategies target individuals who are at high risk of cardiovascular disease, there is rising interest towards primordial prevention that focuses on preventing the development of risk factors upstream of disease detection. Therefore, we review the advantages of primordial prevention interventions on minimizing future cardiovascular events.

Recent findings: Primordial prevention of atherosclerotic cardiovascular disease involves behavioral, genetic, and environmental strategies, starting from fetal/infant health and continuing throughout childhood and young adulthood. Early interventions focusing on modifiable risk factors such as physical inactivity, non-ideal body weight, smoking, and environmental pollutants are important towards preventing the initial occurrence of risk factors such as hypertension, dyslipidemia, and diabetes to ultimately reduce cardiovascular disease. Implementing primordial prevention strategies early on in life can minimize cardiovascular events and lead to healthy aging in the population. Future studies can further evaluate the effectiveness of various primordial prevention strategies.

Introduction: Heart failure (HF) is a significant worldwide concern due to its substantial impact on mortality rates and recurrent hospitalizations. The relationship between recurrent hospitalizations and mortality in individuals diagnosed with heart failure has been the subject of conflicting findings in previous studies. A meta-analysis was conducted to investigate the association between recurrent heart failure hospitalizations (HFHs) and mortality.

Methods: We conducted a systematic search across various online databases, such as PubMed, Embase, Web of Science, ProQuest, Scopus, Science Direct, and Google Scholar, to locate studies that examined the connection between recurrent HFHs and cardiovascular (CV) mortality as well as all-cause mortality until January 2023. To evaluate the heterogeneity among the studies, we employed I2 and Cochran's Q test.

Results: In total, 143,867 participants from seven studies were included in the analysis. Recurrent HFHs were found to be strongly associated with elevated risks of both cardiovascular (CV) mortality and all-cause mortality. The pooled hazard ratios (HRs) indicated a non-significant association for CV mortality (HR = 4.28, 95% CI: 0.86-7.71) but a significant association for all-cause mortality (HR = 2.76, 95% CI: 2.05-3.48). Subgroup analyses revealed a reduction in heterogeneity when stratified by factors such as quality score, sample size, hypertension comorbidity, number of recurrent HFHs, and follow-up time. A clear correlation was observed between the frequency of HFH and the mortality risk. Various subgroups, including those with diabetes, atrial fibrillation, and chronic kidney disease, showed significant associations between recurrent HFHs and all-cause mortality. Additionally, recurrent HFHs were significantly associated with CV mortality in subgroups such as heart failure with reduced ejection fraction (HFrEF), atrial fibrillation, and diabetes.

Conclusion: This meta-analysis provides evidence of an association between recurrent HFH and elevated risk of both CV mortality and all-cause mortality. The findings consistently indicate that a higher frequency of HFH is strongly associated with an increased likelihood of mortality.

Purpose of review: Cardiovascular diseases (CVDs) are the leading cause of mortality in Saudi Arabia. Cardiac rehabilitation (CR) is one of the well-known interventions to control and minimize the burden of CVDs. Despite recommendations, CR utilization remains suboptimal in Saudi Arabia due to many reasons, including limited awareness, logistical barriers, shortage of specialized facilities and trained professionals, and perceptions about CVDs illness. This review is to evaluate the current status, effectiveness, accessibility, and challenges of CR utilization in Saudi Arabia, and to explore potential future directions for improving these services. The review addresses key questions regarding the incidence of CVDs, the characteristics of existing CR programs, barriers to CR access, and stakeholder perspectives.

Recent findings: Recent studies demonstrate that the effectiveness of CR, particularly exercise training, in improving outcomes for post-coronary artery bypass grafting (CABG) patients is well-documented, though data on its impact on other cardiac conditions is limited. There are significant barriers to CR utilization in Saudi Arabia, including limited awareness, logistical challenges, a shortage of specialized facilities and trained professionals, and cultural perceptions about CVD. Stakeholder perspectives highlight the necessity for culturally sensitive and inclusive approaches, particularly in addressing gender-specific needs and enhancing patient-provider communication. The Saudi Vision 2030 presents opportunities to expand and enhance CR services in alignment with international standards. This review found that while CR is a crucial intervention for managing CVDs, its utilization in Saudi Arabia is suboptimal due to various barriers. To improve CR access and effectiveness, future strategies should focus on increasing public and professional awareness, developing infrastructure, training healthcare professionals, and fostering public-private partnerships. These measures are essential to making CR more accessible and tailored to the diverse needs of the Saudi population, ultimately enhancing the quality of cardiovascular care and patient outcomes in the region.

Purpose of review: This review seeks to describe the updates in the literature - particularly with regards to the epidemiology and diagnosis of Chagas disease. Additionally, this paper describes updates to the antiparasitic treatment for Chagas disease.

Recent findings: With regards to changing epidemiology, autochthonous cases are being found within the USA in addition to Latin America. Additionally, there appears to be more intermixing of discrete typing units-meaning, they are not confined to specific geographic regions. Screening for Chagas disease is recommended in persons who lived in areas with endemic Chagas, persons wtih family member diagnosed with Chagas Disease, persons who have lived in homes of natural material in Latin America, and persons with history of kissing bug bites. Treatment for the parasitic infection remains limited to benznidazole and nifurtimox, and the role of these treatments in Chagas cardiomyopathy has not yet been definitively defined. Finally, indications for and management of heart transplant in the setting of Chagas disease are discussed.

Future research: Use of antiparasitics during chronic chagas disease should be further explored. Additionally, future research identifying other markers of infection would be valuable to defining cure from infection.
