RESUMO
OBJECTIVE: A substantial proportion of patients with rheumatic heart disease (RHD) have tricuspid regurgitation (TR). This study aimed to identify the impact of functional TR on clinical outcomes and predictors of progression in a large population of patients with RHD. METHODS: A total of 645 patients with RHD were enrolled, mean age of 47±12 years, 85% female. Functional TR was graded as absent, mild, moderate or severe. TR progression was defined either as worsening of TR degree from baseline to the last follow-up echocardiogram or severe TR at baseline that required surgery or died. Incidence of TR progression was estimated accounting for competing risks. RESULTS: Functional TR was absent in 3.4%, mild in 83.7%, moderate in 8.5% and severe in 4.3%. Moderate and severe functional TR was associated with adverse outcome (HR 1.91 (95% CI 1.15 to 3.2) for moderate, and 2.30 (95% CI 1.28 to 4.13) for severe TR, after adjustment for other prognostic variables. Event-free survival rate at 3-year follow-up was 91%, 72% and 62% in patients with no or mild, moderate and severe TR, respectively. During mean follow-up of 4.1 years, TR progression occurred in 83 patients (13%) with an overall incidence of 3.7 events (95% CI 2.9 to 4.5) per 100 patient-years. In the Cox model, age (HR 1.71, 95% CI 1.34 to 2.17), New York Heart Association functional class III/IV (HR 2.57, 95% CI 1.54 to 4.30), right atrial area (HR 1.52, 95% CI 1.10 to 2.10) and right ventricular (RV) dysfunction (HR 2.02, 95% CI 1.07 to 3.84) were predictors of TR progression. By considering competing risk, the effect of RV dysfunction on TR progression risk was attenuated. CONCLUSIONS: In patients with RHD, functional TR was frequent and associated with adverse outcomes. TR may progress over time, mainly related to right-sided cardiac chambers remodelling.

Cardiovascular diseases are the main cause of mortality in men and women worldwide, surpassing mortality from all associated neoplasms. In women, its prevalence and mortality increase at menopause, but complications of reproductive age, such as preeclampsia and eclampsia, lead to increased cardiovascular risk throughout their lives. Coronary ischemic disease is is the leading cause of death in Brazil and worldwide, with atherosclerotic disease being the principal pathophysiological mechanism. However, in women, other mechanisms are associated with myocardial ischemia, such as microcirculation disease and/or vasospasm, due to the anatomical and hormonal characteristics of women in different stages of their lives. Knowledge of the most prevalent cardiovascular diseases in women, as well as the specific risk factors, the traditional ones with the greatest impact, and the under-recognized ones, is of fundamental importance in their risk stratification, diagnosis, and management, fundamentally aiming at reducing mortality.

Abstract Metabolic syndrome (MetS) is increasing at epidemic proportions worldwide. MetS and its components are frequent among Brazilian women (41.8%). Women are affected by changes in adipose tissue distribution, lipid profile, insulin resistance (IR), and vascular remodeling during their lives. These changes result from the lack of estrogen after menopause. There have been various attempts to propose a uniform origin for the clustering of the MetS components, including genetics, IR, obesity, lifestyle, sleep disturbances, inflammation, fetal and neonatal programming, and disturbed circadian rhythm of the body functions. The proinflammatory and prothrombotic state in MetS is well-defined. Socioeconomic and lifestyle-related factors are also essential triggers of MetS, which is associated with a higher risk for coronary artery diseases (CAD) and stroke in women. Population measures in health and community medicine, such as continuing education on the importance of lifestyle change to reduce cardiovascular risks from early childhood, are fundamental strategies. Statins reduce high-sensitivity C-reactive protein blood levels and treat high cholesterol. According to the patient, hypoglycemic agents, such as dipeptidyl peptidase-4 (DPP-4) inhibitors, glucagon-like peptide-1(GLP-1a), and sodium-glucose transport protein 2 (SGLT2) inhibitors, in addition to metformin, have their indication due to their beneficial cardiometabolic and vascular effects. Angiotensin-converting enzyme inhibitor (ACEI) and angiotensin-receptor blocker (ARB) should be the first choice to treat hypertension in postmenopausal womem. The recognition of the different gender- and age-specific risk factors, allowing for specific and targeted interventions, is fundamental, especially for women.
