RESUMEN
BACKGROUND: Existing data on female sex and excess cardiovascular mortality after myocardial infarction (MI) mostly come from high-income countries (HICs). This study aimed to investigate how sex disparities in treatments and outcomes vary across countries with different income levels. METHODS: Data from the ISACS-Archives registry included 22 087 MI patients from 6 HICs and 6 middle-income countries (MICs). MI data were disaggregated by clinical presentation: ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI). The primary outcome was 30-day mortality. RESULTS: Among STEMI patients, women in MICs had nearly double the 30-day mortality rate of men (12.4% versus 5.8%; adjusted risk ratio [RR] 2.30, 95% CI 1.98-2.68). This difference was less pronounced in HICs (6.8% versus 5.1%; RR 1.36, 95% CI 1.05-1.75). Despite more frequent treatments and timely revascularization in MICs, sex-based mortality differences persisted even after revascularization (8.0% versus 4.1%; RR 2.05, 95% CI, 1.68-2.50 in MICs and 5.6% versus 2.6%; RR 2.17, 95% CI 1.48-3.18) in HICs. Additionally, women from MICs had higher diabetes rates compared to HICs (31.8% versus 25.1%, standardized difference = 0.15). NSTEMI outcomes were relatively similar between sexes and income groups. CONCLUSIONS: Sex disparities in mortality rates following STEMI are more pronounced in MICs compared to HICs. These disparities cannot be solely attributed to sex-related inequities in revascularization. Variations in mortality may also be influenced by sex differences in socioeconomic factors and baseline comorbidities.
RESUMEN
Addressing sex differences and disparities in coronary heart disease (CHD) involves achieving both horizontal and vertical equity in healthcare. Horizontal equity in the context of CHD means that both men and women with comparable health statuses should have equal access to diagnosis, treatment, and management of CHD. To achieve this, it is crucial to promote awareness among the general public about the signs and symptoms of CHD in both sexes, so that both women and men may seek timely medical attention. Women often face inequity in the treatment of cardiovascular disease. Current guidelines do not differ based on sex, but their applications based on gender do differ. Vertical equity means tailoring healthcare to allow equitable care for all. Steps towards achieving this include developing treatment protocols and guidelines that consider the unique aspects of CHD in women. It also requires implementing guidelines equally, when there is not sex difference rather than inequities in application of guideline directed care.

Background: The age-standardized death rates under 65 years from ischemic heart disease in South Eastern Europe are approximately twice as high than the Western Europe average, but the reasons are not completely recognized. The aim of the present study was to address this issue by collecting and analyzing data from a large, multinational cohort. Methods: We enrolled 70,953 Caucasian patients with first acute coronary syndrome, from 36 urban hospital in 7 South Eastern European countries and assessed their life expectancy free of acute coronary syndrome and mortality within 30 days after hospital admission from acute coronary syndrome as estimated in relation to dichotomous categories of traditional risk factors (current smoking, hypertension, diabetes and hypercholesterolemia) stratified according to sex. Findings: Compared with patients without any baseline traditional risk factors, the presence of all four risk factors was associated with a 5-year shorter life expectancy free of acute coronary syndrome (women: from 67.1 ± 12.0 to 61.9 ± 10.3 years; r = -0.089; p < 0.001 and men: from 62.8 ± 12.2 to 58.9 ± 9.9 years; r = -0.096; p < 0.001). Premature acute coronary syndrome (women <67 years and men <63 years) was remarkably related to current smoking and hypercholesterolemia among women (RRs: 3.96; 95% CI: 3.72-4.20 and 1.31; 95% CI: 1.25-1.38, respectively) and men (RRs: 2.82; 95% CI: 2.71-2.93 and 1.39; 95% CI: 1.34-1.45, respectively). Diabetes was most strongly associated with death from premature acute coronary syndrome either in women (RR: 1.52; 95% CI: 1.29-1.79) or men (RR: 1.63; 95% CI: 1.41-1.89). Interpretation: Public health policies in South Eastern Europe should place significant emphasis on the four traditional risk factors and the associated lifestyle behaviors to reduce the epidemic of premature ischemic heart disease.

The combination of classic chemotherapy agents like anthracyclines with novel targeted medications has had a positive impact on women's survival from breast cancer. GnRH analogues are primarily employed to temporarily suppress ovarian function in premenopausal women with hormone-receptor-positive (HR+) breast cancer. Despite their benefits, the true degree of their collateral effects has been widely understudied, especially when it comes to ischemic heart disease. This review aims at summarizing the current state of the art on this issue, with particular focus on the risk for cardiotoxicity associated with the combined use of GnRH analogues and anthracyclines.
RESUMEN
Cardiovascular inequalities remain pervasive in the European countries. Disparities in disease burden is apparent among population groups based on sex, ethnicity, economic status or geography. To address this challenge, The Lancet Regional Health - Europe convened experts from a broad range of countries to assess the current state of knowledge of cardiovascular disease inequalities across Europe. This report presents the main challenges in Eastern Europe. There were pronounced variations in cardiovascular disease mortality rates across Eastern European countries with a remarkably high disease burden in the North-Eastern Europe. There were also significant differences in access and delivery to healthcare and unmet healthcare needs. Addressing the cardiovascular determinants of health and reducing health disparities in its many dimensions has long been a priority of the European Parliament's work through resolutions and by financing pilot projects. Yet, despite these efforts, few large-scale studies have been conducted to examine the feasibility of reducing cardiovascular disparities in Eastern Europe. There is an urgent need for improved data, measurements, reporting, and comparisons; and for dedicated, collaborative research. There is also a need for a broader understanding of the typology of actions needed to tackle cardiovascular inequalities and a clear political will.
RESUMEN
Background Empiric antimicrobial therapy with azithromycin is highly used in patients admitted to the hospital with COVID-19, despite prior research suggesting that azithromycin may be associated with increased risk of cardiovascular events. Methods and Results This study was conducted using data from the ISACS-COVID-19 (International Survey of Acute Coronavirus Syndromes-COVID-19) registry. Patients with a confirmed diagnosis of SARS-CoV-2 infection were eligible for inclusion. The study included 793 patients exposed to azithromycin within 24 hours from hospital admission and 2141 patients who received only standard care. The primary exposure was cardiovascular disease (CVD). Main outcome measures were 30-day mortality and acute heart failure (AHF). Among 2934 patients, 1066 (36.4%) had preexisting CVD. A total of 617 (21.0%) died, and 253 (8.6%) had AHF. Azithromycin therapy was consistently associated with an increased risk of AHF in patients with preexisting CVD (risk ratio [RR], 1.48 [95% CI, 1.06-2.06]). Receiving azithromycin versus standard care was not significantly associated with death (RR, 0.94 [95% CI, 0.69-1.28]). By contrast, we found significantly reduced odds of death (RR, 0.57 [95% CI, 0.42-0.79]) and no significant increase in AHF (RR, 1.23 [95% CI, 0.75-2.04]) in patients without prior CVD. The relative risks of death from the 2 subgroups were significantly different from each other (Pinteraction=0.01). Statistically significant association was observed between AHF and death (odds ratio, 2.28 [95% CI, 1.34-3.90]). Conclusions These findings suggest that azithromycin use in patients with COVID-19 and prior history of CVD is significantly associated with an increased risk of AHF and all-cause 30-day mortality.

AIMS: Previous analyses on sex differences in case fatality rates at population-level data had limited adjustment for key patient clinical characteristics thought to be associated with coronavirus disease 2019 (COVID-19) outcomes. We aimed to estimate the risk of specific organ dysfunctions and mortality in women and men. METHODS AND RESULTS: This retrospective cross-sectional study included 17 hospitals within 5 European countries participating in the International Survey of Acute Coronavirus Syndromes COVID-19 (NCT05188612). Participants were individuals hospitalized with positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) from March 2020 to February 2022. Risk-adjusted ratios (RRs) of in-hospital mortality, acute respiratory failure (ARF), acute heart failure (AHF), and acute kidney injury (AKI) were calculated for women vs. men. Estimates were evaluated by inverse probability weighting and logistic regression models. The overall care cohort included 4499 patients with COVID-19-associated hospitalizations. Of these, 1524 (33.9%) were admitted to intensive care unit (ICU), and 1117 (24.8%) died during hospitalization. Compared with men, women were less likely to be admitted to ICU [RR: 0.80; 95% confidence interval (CI): 0.71-0.91]. In general wards (GWs) and ICU cohorts, the adjusted women-to-men RRs for in-hospital mortality were of 1.13 (95% CI: 0.90-1.42) and 0.86 (95% CI: 0.70-1.05; pinteraction = 0.04). Development of AHF, AKI, and ARF was associated with increased mortality risk (odds ratios: 2.27, 95% CI: 1.73-2.98; 3.85, 95% CI: 3.21-4.63; and 3.95, 95% CI: 3.04-5.14, respectively). The adjusted RRs for AKI and ARF were comparable among women and men regardless of intensity of care. In contrast, female sex was associated with higher odds for AHF in GW, but not in ICU (RRs: 1.25; 95% CI: 0.94-1.67 vs. 0.83; 95% CI: 0.59-1.16, pinteraction = 0.04). CONCLUSIONS: Women in GW were at increased risk of AHF and in-hospital mortality for COVID-19 compared with men. For patients receiving ICU care, fatal complications including AHF and mortality appeared to be independent of sex. Equitable access to COVID-19 ICU care is needed to minimize the unfavourable outcome of women presenting with COVID-19-related complications.

Coronary artery disease (CAD) is the leading cause of mortality globally. Although substantial advances have been made in the diagnosis, management, and risk stratification of CAD, there is still a need for novel diagnostic biomarkers and new therapeutic targets to prevent the epidemic of the disease. Recently, growing evidence has linked dysregulated microRNAs (miRNAs) to cardiovascular diseases, including CAD. miRNAs are endogenous, stable, single-stranded, short, non-coding RNAs, and may have utility as diagnostic and prognostic biomarkers for CAD. Dysregulated miRNAs are involved in regulating lipid and glucose homeostasis pathways, reninangiotensin- aldosterone pathways, inflammation, endothelial and vascular smooth cell phenotypes promoting atherosclerotic plaque development, progression, and instability. Additionally, miRNAs are stable and easily accessible in the extracellular space, may reside in microvesicles, and are detectable in serum or plasma, making them attractive biomarkers for the diagnosis and prognosis of cardiovascular disease. Accumulating studies suggest that miRNAs could be useful biomarkers for early discrimination of patients presenting with myocarditis or Takotsubo syndrome from those with a diagnosis of acute myocardial infarction, early prognostication of patients presenting with acute coronary syndromes, and accurate detection of left ventricular remodeling after a chronic or acute ischemic event. Moreover, miRNAs represent potential novel therapeutic targets for CAD or other cardiovascular diseases. This review provides an overview of the effects of the entire spectrum of CAD, its major risk factors, and complications on levels of circulating miRNAs, as well as the limitations and challenges of their potential clinical applications.

Background: There have been conflicting reports regarding outcomes in women presenting with an acute coronary syndrome (ACS). Objectives: The objective of the study was to examine sex-specific differences in 30-day mortality in patients with ACS and acute heart failure (HF) at the time of presentation. Methods: This was a retrospective study of patients included in the International Survey of Acute Coronary Syndromes-ARCHIVES (ISACS-ARCHIVES; NCT04008173). Acute HF was defined as Killip classes ≥2. Participants were stratified according to ACS presentation: ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation ACS (NSTE-ACS). Differences in 30-day mortality and acute HF presentation at admission between sexes were examined using inverse propensity weighting based on the propensity score. Estimates were compared by test of interaction on the log scale. Results: A total of 87,812 patients were included, of whom 30,922 (35.2%) were women. Mortality was higher in women compared with men in those presenting with STEMI (risk ratio [RR]: 1.65; 95% CI: 1.56-1.73) and NSTE-ACS (RR: 1.18; 95% CI: 1.09-1.28; P interaction <0.001). Acute HF was more common in women when compared to men with STEMI (RR: 1.24; 95% CI: 1.20-1.29) but not in those with NSTE-ACS (RR: 1.02; 95% CI: 0.97-1.08) (P interaction <0.001). The presence of acute HF increased the risk of mortality for both sexes (odds ratio: 6.60; 95% CI: 6.25-6.98). Conclusions: In patients presenting with ACS, mortality is higher in women. The presence of acute HF at hospital presentation increases the risk of mortality in both sexes. Women with STEMI are more likely to present with acute HF and this may, in part, explain sex differences in mortality. These findings may be helpful to improve sex-specific personalized risk stratification.
RESUMEN
BACKGROUND: There is uncertainty regarding the impact of statins on the risk of atherosclerotic cardiovascular disease (ASCVD) and its major complication, acute heart failure (AHF). OBJECTIVES: The aim of this study was to investigate whether previous statin therapy translates into lower AHF events and improved survival from AHF among patients presenting with an acute coronary syndrome (ACS) as a first manifestation of ASCVD. METHODS: Data were drawn from the International Survey of Acute Coronary Syndromes Archives. The study participants consisted of 14,542 Caucasian patients presenting with ACS without previous ASCVD events. Statin users before the index event were compared with nonusers by using inverse probability weighting models. Estimates were compared by test of interaction on the log scale. Main outcome measures were the incidence of AHF according to Killip class and the rate of 30-day all-cause mortality in patients presenting with AHF. RESULTS: Previous statin therapy was associated with a significantly decreased rate of AHF on admission (4.3% absolute risk reduction; risk ratio [RR]: 0.72; 95% CI: 0.62-0.83) regardless of younger (40-75 years) or older age (interaction P = 0.27) and sex (interaction P = 0.22). Moreover, previous statin therapy predicted a lower risk of 30-day mortality in the subset of patients presenting with AHF on admission (5.2 % absolute risk reduction; RR: 0.71; 95% CI: 0.50-0.99). CONCLUSIONS: Among adults presenting with ACS as a first manifestation of ASCVD, previous statin therapy is associated with a reduced risk of AHF and improved survival from AHF.

Cardiovascular diseases and cancer are the leading cause of morbidity and mortality globally. Cardiotoxicity from chemotherapeutic agents results in substantial morbidity and mortality in cancer survivors and patients with active cancer. Cardiotoxicity induced by 5-fluorouracil (5-FU) has been well established, yet its incidence, mechanisms, and manifestation remain poorly defined. Ischemia secondary to coronary artery vasospasm is thought to be the most frequent cardiotoxic effect of 5-FU. The available evidence of 5-FU-induced epicardial coronary artery spasm and coronary microvascular dysfunction suggests that endothelial dysfunction or primary vascular smooth muscle dysfunction (an endothelial-independent mechanism) are the possible contributing factors to this form of cardiotoxicity. In patients with 5-FU-related coronary artery vasospasm, termination of chemotherapy and administration of nitrates or calcium channel blockers may improve ischemic symptoms. However, there are variable results after administration of nitrates or calcium channel blockers in patients treated with 5-FU presumed to have myocardial ischemia, suggesting mechanisms other than impaired vasodilatory response. Clinicians should investigate whether chest pain and ECG changes can reasonably be attributed to 5-FU-induced cardiotoxicity. More prospective data and clinical randomized trials are required to understand and mitigate potentially adverse outcomes from 5-FU-induced cardiotoxicity.
RESUMEN
In recent years, increasing attention has been reserved to the analysis of sex-related differences in pathophysiology and prognosis of ischemic heart disease (IHD). The traditional conventional cardiovascular risk factors (hypertension, hypercholesteremia, diabetes mellitus and cigarette smoking) are still considered the major risk factors for IHD in both sexes. Nevertheless, recent studies show that they may interact with male and female coronary anatomy in a different manner. The path to sex-specific risk stratification of IHD is also supported by differences in inflammation and necrosis biomarkers (such as C-reactive protein and troponins, respectively). Indeed, large cohort studies often show different mean values of these markers in men and women. The current review summarizes the state-of-art knowledge on sex-related differences in cardiovascular risk factors and cardiac biomarkers with a prognostic value.

AIMS: We undertook a propensity match-weighted cohort study to investigate whether statin treatment recommendations for statins translate into improved cardiovascular (CV) outcomes in the current routine clinical care of the elderly. METHODS AND RESULTS: We included in our analysis (ISACS Archives -NCT04008173) a total of 5619 Caucasian patients with no known prior history of CV disease who presented to hospital with a first manifestation of CV disease with age of 65 years or older. The risk of ST-segment elevation myocardial infarction (STEMI) was much lower in statin users than in non-users in both patients aged 65-75 years [14.7% absolute risk reduction; relative risk (RR): 0.55, 95% CI 0.45-0.66] and those aged 76 years and older (13.3% absolute risk reduction; RR: 0.58, 95% CI 0.46-0.72). Estimates were similar in patients with and without history of hypercholesterolaemia (interaction test; P-values = 0.24 and 0.35). Proportional reductions in STEMI diminished with female sex in the old (P for interaction = 0.002), but not in the very old age (P for interaction = 0.26). We also observed a remarkable reduction in the risk of 30 day mortality from STEMI with statin therapy in both age groups (10.2% absolute risk reduction; RR: 0.39; 95% CI 0.23-0.68 for patients aged 76 or over and 3.8% absolute risk reduction; RR 0.37; 95% CI 0.17-0.82 for patients aged 65-75 years old; interaction test, P-value = 0.46). CONCLUSIONS: Preventive statin therapy in the elderly reduces the risk of STEMI with benefits in mortality from STEMI, irrespective of the presence of a history of hypercholesterolaemia. This effect persists after the age of 76 years. Benefits are less pronounced in women. Randomized clinical trials may contribute to more definitively determine the role of statin therapy in the elderly.

Regular aerobic exercise (RAEX) elicits several positive adaptations in all organs and tissues of the body, culminating in improved health and well-being. Indeed, in over half a century, many studies have shown the benefit of RAEX on cardiovascular outcome in terms of morbidity and mortality. RAEX elicits a wide range of functional and structural adaptations in the heart and its coronary circulation, all of which are to maintain optimal myocardial oxygen and nutritional supply during increased demand. Although there is no evidence suggesting that oxidative metabolism is limited by coronary blood flow (CBF) rate in the normal heart even during maximal exercise, increased CBF and capillary exchange capacities have been reported. Adaptations of coronary macro- and microvessels include outward remodelling of epicardial coronary arteries, increased coronary arteriolar size and density, and increased capillary surface area. In addition, there are adjustments in the neural and endothelial regulation of coronary macrovascular tone. Similarly, there are several adaptations at the level of microcirculation, including enhanced (such as nitric oxide mediated) smooth muscle-dependent pressure-induced myogenic constriction and upregulated endothelium-dependent/shear-stress-induced dilation, increasing the range of diameter change. Alterations in the signalling interaction between coronary vessels and cardiac metabolism have also been described. At the molecular and cellular level, ion channels are key players in the local coronary vascular adaptations to RAEX, with enhanced activation of influx of Ca2+ contributing to the increased myogenic tone (via voltage-gated Ca2+ channels) as well as the enhanced endothelium-dependent dilation (via TRPV4 channels). Finally, RAEX elicits a number of beneficial effects on several haemorheological variables that may further improve CBF and myocardial oxygen delivery and nutrient exchange in the microcirculation by stabilizing and extending the range and further optimizing the regulation of myocardial blood flow during exercise. These adaptations also act to prevent and/or delay the development of coronary and cardiac diseases.

AIMS: The use of digitalis has been plagued by controversy since its initial use. We aimed to determine the relationship between digoxin use and outcomes in hospitalized patients with acute coronary syndromes (ACSs) complicated by heart failure (HF) accounting for sex difference and prior heart diseases. METHODS AND RESULTS: Of the 25 187 patients presenting with acute HF (Killip class ≥2) in the International Survey of Acute Coronary Syndromes Archives (NCT04008173) registry, 4722 (18.7%) received digoxin on hospital admission. The main outcome measure was all-cause 30-day mortality. Estimates were evaluated by inverse probability of treatment weighting models. Women who received digoxin had a higher rate of death than women who did not receive it [33.8% vs. 29.2%; relative risk (RR) ratio: 1.24; 95% confidence interval (CI): 1.12-1.37]. Similar odds for mortality with digoxin were observed in men (28.5% vs. 24.9%; RR ratio: 1.20; 95% CI: 1.10-1.32). Comparable results were obtained in patients with no prior coronary heart disease (RR ratio: 1.26; 95% CI: 1.10-1.45 in women and RR ratio: 1.21; 95% CI: 1.06-1.39 in men) and those in sinus rhythm at admission (RR ratio: 1.34; 95% CI: 1.15-1.54 in women and RR ratio: 1.26; 95% CI: 1.10-1.45 in men). CONCLUSION: Digoxin therapy is associated with an increased risk of early death among women and men with ACS complicated by HF. This finding highlights the need for re-examination of digoxin use in the clinical setting of ACS.
