Dual-pathway Inhibition with Low-dose Aspirin and Rivaroxaban versus Aspirin Monotherapy in Patients with Coronary Artery Disease and Peripheral Artery Disease: Systematic Literature Review and Meta-analysis.

Background: Low-dose aspirin lowers cardiovascular event risk; dual-pathway inhibition (DPI) using low-dose aspirin with low-dose rivaroxaban may reduce this risk further. A systematic literature review and meta-analysis compared the efficacy, safety and net clinical benefit (NCB) of DPI with aspirin. Methods: PubMed and Embase were searched for randomised controlled trials reporting clinical efficacy, safety and NCB of DPI compared with aspirin alone in patients with coronary artery disease (CAD) and/or peripheral artery disease. Six articles representing four trials were included. Results: DPI versus aspirin alone significantly reduced major adverse cardiovascular events (HR 0.77; 95% CI [0.69-0.87]; p<0.01), increased International Society on Thrombosis and Haemostasis major bleeding events (HR 1.67; 95% CI [1.37-2.02]; p<0.01) and resulted in a significant NCB (HR 0.79; 95% CI [0.70-0.90]; p<0.01). Conclusion: These results underscore the potential benefit of DPI in patients with CAD, including those in the immediate post-acute coronary syndrome stage and with established CAD, as well as patients with peripheral artery disease.

Acute pancreatitis due to different semaglutide regimens: An updated meta-analysis.

OBJECTIVES: Some concerns persist regarding the safety of semaglutide. The objective of this updated meta-analysis is to assess the risk of acute pancreatitis with the use of semaglutide, assessing the results according to the different administration regimens. METHODS: We performed an updated meta-analysis of randomised, placebo-controlled studies of semaglutide therapy that report acute pancreatitis. This meta-analysis was performed in line with PRISMA guidelines. A global and stratified analysis according to the therapeutic scheme used was performed using the fixed-effects model. RESULTS: Twenty-one eligible trials of semaglutide, including 34,721 patients, were identified and considered eligible for the analyses. Globally, semaglutide therapy was not associated with an increased risk of acute pancreatitis (OR 0.7; 95% CI 0.5-1.2, I2 0%). When we analysed the studies according to the different schemes used, the results were similar (group with oral semaglutide: OR 0.40; 95% CI 0.10-1.60, I2 0%; group with low subcutaneous doses of semaglutide: OR 0.80; 95% CI 0.40-1.90, I2 0%; group with high subcutaneous doses of semaglutide: OR 0.70; 95% CI 0.50-1.20, I2 0%; interaction p-value=0.689). CONCLUSION: This updated meta-analysis demonstrates that the use of semaglutide is not associated with an increased risk of acute pancreatitis compared to placebo. In the stratified analysis, the results were similar with the different semaglutide regimens analysed.

Elevated Lipoprotein(a) Levels and Atrial Fibrillation: A Systematic Review.

Objective: The role of lipoprotein(a) (Lp[a]) as a possibly causal risk factor for atherosclerotic cardiovascular disease has been well established. However, the clinical evidence regarding the association between Lp(a) levels and atrial fibrillation (AF) remains limited and inconsistent. This study aimed to analyze the association between elevated Lp(a) levels or single-nucleotide polymorphisms (SNPs) related to high levels of Lp(a) and AF. Methods: This systematic review was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. A literature search was performed to identify studies that evaluated the association between Lp(a) levels or SNPs related to high levels of Lp(a) and AF. Observational studies with a cross-sectional, case-control, or cohort design were included in this systematic review, without limitations according to language, country, or publication type. Results: Eleven observational studies including 1,246,817 patients were eligible for this systematic review. Two cross-sectional studies, 5 prospective/retrospective cohort studies, and 4 Mendelian randomization studies were analyzed. Two cross-sectional studies that compared Lp(a) levels between patients with and without AF showed conflicting results. Cohort studies that evaluated the incidence of AF according to Lp(a) levels showed different results: no association (3 studies), a positive association (1 study), and an inverse relationship (1 study). Finally, Mendelian randomization studies also showed heterogeneous results (positive association: 2 studies; inverse association: 1 study; no association: 1 study). Conclusion: Although there could be an association between Lp(a) levels and AF, the results of the studies published to date are contradictory and not yet definitive. Therefore, further research should clarify this issue.

Relationship between epicardial adipose tissue, systemic inflammatory diseases, and subclinical atheromatosis: A systematic review.

BACKGROUND AND AIMS: Systemic inflammatory diseases could act as an unfavorable condition in which epicardial adipose tissue (EAT) becomes harmful to cardiovascular health. The objectives were: (a) to quantitatively compare the presence of EAT between patients with systemic inflammatory diseases and controls; (b) to analyze the association between EAT and subclinical atheromatosis in individuals with systemic inflammatory diseases. METHODS: Studies that have quantified EAT in a population with systemic inflammatory diseases compared to a control group, or that describe the association between EAT and the presence of subclinical atheromatosis in patients with systemic inflammatory diseases were included. A quantitative analysis was performed for the first objective. This systematic review was performed according to PRISMA guidelines. RESULTS: Twenty-one studies including 1448 patients with systemic inflammatory diseases, were considered eligible for this study. Patients with systemic inflammatory disease have a higher volume (MD: 10.4cm3 [1.8-19.1]; p<0.01), higher thickness (MD: 1.0mm [0.8-1.2]; p<0.01), and a statistically non-significant higher area (MD: 3.1cm2 [1.0-5.2]; p=0.46) of EAT compared to the control group. Most studies reported a significant association between EAT and subclinical atheromatosis in patients with different systemic inflammatory diseases. CONCLUSION: This study demonstrated that EAT is increased in patients with systemic inflammatory diseases compared with healthy controls, and that EAT measurement is closely correlated with subclinical atherosclerosis in these patients. The causality of this association should be tested in prospective studies.

Objetivos: Las enfermedades inflamatorias sistémicas podrían aumentar el riesgo cardiovascular asociados a un aumento del tejido adiposo epicárdico (TAE). Los objetivos de este estudio, fueron: a) comparar cuantitativamente la presencia de TAE entre pacientes con enfermedades inflamatorias sistémicas y controles, y b) analizar la asociación entre TAE y atero“matosis subclínica en individuos con enfermedades inflamatorias sistémicas. Métodos: Se incluyeron estudios que hayan cuantificado la TAE en una población con enfermedades inflamatorias sistémicas frente a un grupo control, o que describan la asociación entre la TEA y la presencia de ateromatosis subclínica en pacientes con enfermedades inflamatorias sistémicas. Para el primer objetivo se realizó un análisis cuantitativo. Esta revisión sistemática se realizó de acuerdo con las guías PRISMA. Resultados: Veintiún estudios que incluyeron 1.448 pacientes con enfermedades inflamatorias sistémicas se consideraron elegibles para este estudio. Los pacientes con enfermedad inflamatoria sistémica tienen mayor volumen (DM: 10,4cm3 [1,8-19,1]; p<0,01), mayor grosor (DM: 1,0mm [0,8-1,2]; p<0,01) y un área mayor estadísticamente no significativa (DM: 3,1cm2 [1,0-5,2]; p=0,46) de EAT en comparación con el grupo de control. La mayoría de los estudios informaron una asociación significativa entre EAT y ateromatosis subclínica en pacientes con diferentes enfermedades inflamatorias sistémicas. Conclusión: Este estudio demostró que la TAE aumenta en pacientes con enfermedades inflamatorias sistémicas en comparación con controles sanos, y que la medición de EAT está estrechamente relacionada con la aterosclerosis subclínica en estos pacientes. La causalidad de esta asociación debe probarse en estudios prospectivos.(AU)

Ethnic/Racial and Geographic Disparities on Major Cardiovascular Events in Glucagon Like Peptide-1 receptor Agonists Trials: A Meta-Analysis.

Higher rates of type 2 diabetes mellitus (T2D) are found among racial and ethnic minorities in the United States. These groups also experience a higher rate of cardiovascular and renal complications. Despite the previously mentioned high risk, these minority groups are usually underrepresented in clinical trials. The purpose of this study was to report the effect of glucagon-like peptide 1 receptor agonists (GLP-1 RAs) on major cardiovascular events (MACE) in subgroup analysis along different ethnic/racial and geographical groups in patients with T2D included in cardiovascular outcomes trials (CVOTs). A meta-analysis of randomized studies that evaluated the use of GLP-1 RAs in patients with T2D and reporting MACE across ethnic/race and geographical regions groups was performed after searching the PubMed/MEDLINE, Embase, Scielo, Google Scholar, and Cochrane Controlled Trials databases. This meta-analysis was performed according to PRISMA guidelines. Measures of the effect size were expressed as odds ratios (ORs). Fixed or random effects models were used. Seven trials, including 58,294 patients, were identified and considered eligible for the analyses. GLP-1 RAs were associated with a reduction in MACE incidence in Europe (OR 0.77, 95% CI: 0.65-0.91) and Asia/Pacific (OR 0.70, 95% CI: 0.55-0.90) regions with no significant reduction observed in North America (OR 0.95, 95% CI: 0.86-1.05) and Latin America (OR 0.87, 95%CI: 0.63-1.21) MACE reduction was observed in all ethnic/race groups evaluated with exception to black patients. In this meta-analysis, we observed ethnic/racial and geographic disparities in MACE reduction with GLP-1 RAs in CVOTs. Consequently, we believe it is essential to systematically include and assess ethnic/racial minorities in clinical studies.

Lipoprotein(a) and heart failure: a systematic review.

The role of lipoprotein(a) [Lp(a)] as a possible causal risk factor for atherosclerotic artery disease and aortic valve stenosis has been well established. However, the information on the association between Lp(a) levels and heart failure (HF) is limited and controversial. The main objective of the present study was to assess the association between Lp(a) levels and HF. This systematic review was performed according to PRISMA guidelines. A literature search was performed to detect studies that evaluated the association between Lp(a) levels and HF. Eight studies, including 73,410 patients, were eligible for this research. Seven prospective or retrospective cohorts and one cross-sectional study were analyzed. Five studies analyzed populations without HF; another three included patients with HF or left ventricular dysfunction. The endpoints evaluated varied according to the study analyzed, including incident HF, HF hospitalizations, and decreased left ventricular ejection fraction. Lp(a) levels were also analyzed in different ways, including analysis of Lp(a) as a continuous or categorical variable (distinct cut-off points or percentiles). Globally, the studies included in this review found predominantly positive results. Data on some relevant subgroups, such as HF of ischemic or non-ischemic etiology or HF with or without left ventricular dysfunction, was poorly reported. This systematic review suggests that there would be a positive relationship between Lp(a) levels and HF. Given the complexity and heterogeneity of HF, new studies should be developed to clarify this topic.

Plasma Lipoprotein(a) Levels in Polycystic Ovary Syndrome: A Systematic Review and Meta-analysis.

INTRODUCTION: The polycystic ovary syndrome (PCOS) may represent an important model of lipid alterations. Lipoprotein(a) [Lp(a)] has emerged as a new marker of cardiovascular risk. AIM: The main objective of this meta-analysis was to analyze the available evidence on Lp(a) levels in patients with PCOS compared to a control group. METHODS: This meta-analysis was performed according to PRISMA guidelines. A literature search was performed to detect studies that have quantified Lp(a) levels in women with PCOS compared to a control group. The primary outcome was Lp(a) levels expressed in mg/dL. Random effects models were used. RESULTS: Twenty-three observational studies including 2,337 patients were identified and considered eligible for this meta-analysis. In the overall analysis, the quantitative analysis showed that patients with PCOS have a higher Lp(a) levels (SMD: 1.1 [95% CI: 0.7 to 1.4]; I2=93%) compared to the control group. The results were similar in the analysis of the subgroups of patients according to body mass index (normal weight group: SMD: 1.2 [95% CI: 0.5 to 1.9], I2=95%; overweight group: SMD: 1.2 [95% CI: 0.5 to 1.8], I2=89%). Sensitivity analysis showed that the results were robust. CONCLUSIONS: This meta-analysis shows that women with PCOS had higher levels of Lp(a) compared to healthy women used as a control group. These findings were observed in both overweight and non-overweight women.

Relationship between lipoprotein(a) levels, cardiovascular outcomes and death in patients with chronic kidney disease: a systematic review of prospective studies.

INTRODUCTION AND AIM: In the general population, high levels of lipoprotein(a) (Lp(a)) are an independent risk factor for atherosclerotic cardiovascular diseases. However, the information available in patients with chronic kidney disease (CKD) is less robust. The main objective of this updated systematic review of prospective studies was to analyze the association between elevated Lp(a) levels and cardiovascular outcomes or death in patients with CKD. METHODS: The PRISMA guidelines were used to carry out this systematic review. Randomized clinical trials or prospective observational studies that evaluated the association between Lp(a) levels and cardiovascular outcomes or death in CKD patients were searched in the current literature. RESULTS: Fifteen studies including 12,260 individuals were identified and considered eligible for this systematic review. In total, 14 prospective cohorts and one post-hoc analysis of a randomized clinical trial were analyzed. Eight studies evaluated hemodialysis patients, one study analyzed patients on peritoneal dialysis, while six studies evaluated subjects with different stages of CKD. Median follow-up duration ranged from 1 to 8.6 years. Our findings showed that elevated Lp(a) values were associated with a higher risk of cardiovascular events or death in most studies, despite adjusting for traditional risk factors. CONCLUSION: The findings of this systematic review show that there is a positive association between Lp(a) levels and fatal and non-fatal cardiovascular events in patients with CKD.

High lipoprotein(a) levels and mitral valve disease: A systematic review.

AIMS: The role of lipoprotein(a) [Lp(a)] as a possibly causal risk factor for atherosclerotic artery disease and aortic valve stenosis has been well established. However, the information available on the association between Lp(a) levels and mitral valve disease is limited and controversial. The main objective of the present study was to assess the association between Lp(a) levels and mitral valve disease. DATA SYNTHESIS: This systematic review was performed according to PRISMA guidelines (PROSPERO CRD42022379044). A literature search was performed to detect studies that evaluated the association between Lp(a) levels or single-nucleotide polymorphisms (SNPs) related to high levels of Lp(a) and mitral valve disease, including mitral valve calcification and valve dysfunction. Eight studies including 1,011,520 individuals were considered eligible for this research. The studies that evaluated the association between Lp(a) levels and prevalent mitral valve calcification found predominantly positive results. Similar findings were reported in two studies that evaluated the SNPs related to high levels of Lp(a). Only two studies evaluated the association of Lp(a) and mitral valve dysfunction, showing contradictory results. CONCLUSIONS: This research showed disparate results regarding the association between Lp(a) levels and mitral valve disease. The association between Lp(a) levels and mitral valve calcification seems more robust and is in line with the findings already demonstrated in aortic valve disease. New studies should be developed to clarify this topic.

Relationship Between Lipoprotein(a) Levels and Cardiovascular Outcomes in Postmenopausal Women: A Systematic Review.

Elevated lipoprotein(a) [Lp(a)] levels are independently associated with atherosclerotic cardiovascular disease, although this association is less explored in postmenopausal women. The main objective of this systematic review was to analyze the association between elevated Lp(a) levels and cardiovascular outcomes in posmenopausal women. Studies that evaluated this association were searched in the current literature. Ten studies including 157.690 women were considered eligible for this study. In total, 4 prospective cohorts, 3 cross-sectional studies, 2 nested case-control studies, and one post-hoc analysis from a randomized clinical trial were analyzed. The included studies showed different results regarding the association between Lp(a) levels and cardiovascular outcomes: a positive association (4 studies), no association (2 studies), or different results depending on the subgroups or outcomes evaluated (4 studies). The results were robust when evaluating coronary events. The reduction in coronary events attributed to a hormone replacement therapy-associated decrease in Lp(a) levels was controversial.

Association between maternal epicardial adipose tissue, gestational diabetes mellitus, and pregnancy-related hypertensive disorders: a systematic review and meta-analysis.

Several small studies have evaluated the association between epicardial adipose tissue (EAT) and pregnancy-related cardiovascular risk factors such as gestational diabetes mellitus (GDM) or hypertensive disorders. The objective of this study was to quantitatively compare EAT thickening between patients with GDM or pregnancy-related hypertensive disorders and healthy controls. This systematic review and meta-analysis were performed according to PRISMA guidelines. A literature search was performed to detect studies that have quantified EAT in women with GDM and pregnancy-related hypertensive disorders compared to a control group. The primary outcome was EAT thickening estimated by ultrasound expressed in millimeters. Random or fixed effects models were used. Nine observational studies including 3146 patients were identified and considered eligible for this systematic review. The quantitative analysis showed that patients with GDM have a higher EAT thickness (mean difference: 1.1 mm [95% confidence interval: 1.0-1.2]; I2 = 24%) compared to the control group. Moreover, patients with pregnancy-related hypertensive disorders showed higher EAT thickness (mean difference: 1.0 mm [95% confidence interval: 0.6-1.4]; I2 = 83%) compared to the control group. In conclusion, this study demonstrated that EAT thickening is increased in patients with GDM and pregnancy-related hypertensive disorders compared with healthy controls. Whether or not this association is causal should be evaluated in prospective studies.

¿Cómo evalúan los cardiólogos la actividad sexual de sus pacientes? / How do cardiologists assess their patients' sexual activity?

Resumen Objetivo: Los pacientes con enfermedad coronaria y sus familias, a menudo enfrentan numerosos cambios en sus vidas. Las recomendaciones sobre la actividad sexual (AS) deben incluirse en el manejo de estos pacientes. El objetivo de este estudio fue evaluar el grado de conocimiento y la actitud profesional con respecto a la AS del paciente. Método: Se realizó un estudio descriptivo y analítico de corte transversal. Los datos se obtuvieron a partir de una encuesta estructurada, virtual y anónima, realizada entre médicos cardiólogos/as. Resultados: Se analizaron 345 encuestas. El 63.8% consideró la disfunción sexual como un marcador de riesgo cardiovascular. Asimismo, el 68.1% consideró relevante o muy relevante interrogar acerca de la AS. En relación con el asesoramiento, se cree que fundamentalmente lo debería comenzar el cardiólogo/a. Se observó una actitud más activa, respecto al abordaje del reinicio de la AS luego de un evento cardiovascular, un mayor interés por capacitarse en temas relacionados con la AS y una mayor solicitud de dosaje de testosterona e indicación de inhibidores de la fosfodiesterasa tipo 5 en los profesionales > 60 años y de sexo masculino en comparación con los médicos más jóvenes o de sexo femenino, respectivamente. Conclusiones: Este estudio mostró que el grado de conocimiento sobre los aspectos relacionados con la AS de los pacientes fue deficiente. Dada la relevancia del tema, consideramos importante fortalecer la educación médica en todos los ámbitos.

Abstract Background: Patients with coronary heart disease and their families often face numerous changes in their lives. Recommendations on sexual activity (SA) should be included in the management of these patients. The objective of this study was to evaluate the degree of knowledge and professional attitude regarding the patient's SA. Objective: A descriptive and analytical cross-sectional study was carried out. The data were obtained from a structured, virtual and anonymous survey that was carried out among cardiologists. Results: Three hundred forty-five surveys were analyzed. In total, 63.8% considered sexual dysfunction as a cardiovascular risk marker. Likewise, 68.1% considered it relevant or very relevant to ask patients about SA. Regarding counseling, it is believed that it should be initiated primarily by the cardiologist. A more active attitude regarding the re-initiation of SA after a cardiovascular event, a greater interest in SA training, more testosterone orders and more indications of phosphodiesterase inhibitors were observed in professionals older than 60 years and male compared to younger or female physicians, respectively. Conclusions: This study showed that the degree of knowledge of the patients about the aspects related to SA was poor. Given the relevance of the topic, we consider it important to strengthen medical education in all areas.

[Statins and influenza mortality: systematic review and meta-analysis]. / Estatinas y mortalidad por influenza: revisión sistemática y meta-análisis.

BACKGROUND: Due to their anti-inflammatory properties, it has been suggested that the use of statins could influence the evolution of influenza virus infection. AIM: To evaluate the effect of statin therapy on mortality from influenza. METHODS: A meta-analysis that included studies evaluating the use of statins in patients with influenza and reporting data on mortality, after searching the PubMed/MEDLINE, Embase, and Cochrane Controlled Trials databases, was performed. A random effects model was applied. The risk of bias was analyzed and a sensitivity analysis was performed. RESULTS: Eight studies (10 independent cohorts), which included a total of 2,390,730 patients, were identified and eligible for analysis. A total of 1,146,995 subjects analyzed received statins, while 1,243,735 subjects were part of the control group. Statin therapy was associated with lower mortality (OR: 0.66; 95% CI: 0.51-0.85). The sensitivity analysis showed that the results were robust. CONCLUSION: Our data suggest that, in a population with influenza, the use of statins was associated with a significant reduction in mortality. These results must be confirmed in future clinical trials.

Reduction of cardiovascular events with the use of lipid-lowering medication in patients with familial hypercholesterolemia or severe primary hypercholesterolemia: A systematic review.

BACKGROUND: Lipid-lowering medication is effective in reducing the risk of cardiovascular disease in several clinical scenarios. However, the evidence in patients with familial hypercholesterolemia (FH) and severe primary hypercholesterolemia is less robust. OBJECTIVES: The main objective of the present systematic review was to analyze the association between lipid-lowering medication and cardiovascular risk reduction in patients with FH or severe primary hypercholesterolemia. METHODS: This systematic review was performed according to PRISMA guidelines. A literature search was performed to detect studies that evaluated the association between lipid-lowering medication and cardiovascular events in FH patients. The diagnosis of FH varied in the studies analyzed. Genetic and clinical criteria or a combination of both were used. Likewise, we considered patients with severe primary hypercholesterolemia. RESULTS: Fourteen studies including 21059 patients were considered eligible for this research. This systematic review showed that the vast majority of the studies with statins reported a significant cardiovascular risk reduction. Statin use was associated with a lower risk of major adverse cardiovascular events (3 studies), coronary heart disease (2 studies), cardiovascular death (4 studies), all-cause mortality (4 studies) and combined endpoint of coronary heart disease and mortality (1 study). When analyzing the association between non-statin lipid-lowering medications and the incidence of cardiovascular events, the results were conflicting. CONCLUSION: Despite the low level of evidence, this systematic review showed that statins reduce cardiovascular events in patients with HeFH. Evidence for other lipid-lowering drugs is not conclusive.

Effect of Yerba Mate (Ilex paraguariensis) on Lipid Levels: A Systematic Review and Meta-Analysis.

Several studies have evaluated the lipid-lowering properties of yerba mate, although the results were conflicting. The objective of this systematic review was to assess the effect of yerba mate consumption on lipid levels. A literature search was performed to detect observational and experimental studies that evaluated the association between yerba mate consumption and lipid levels. A quantitative analysis was performed with the subgroup of experimental studies. A meta-regression was performed considering the difference in baseline lipid values between the intervention and control groups as a covariate. Thirteen studies were considered eligible for this systematic review and seven studies (378 patients) were selected for quantitative analysis. In the qualitative analysis, the results were conflicting, both in the observational and in the experimental studies. In quantitative analysis, we found no differences in total cholesterol [mean difference 6.4 (CI 95% -2.2 to 15.0)], LDL-C [mean difference 5.5 (CI 95% - 1.5 to 12.6)], HDL-C [mean difference 0.4 (CI 95% -2.8 to 3.7)] and triglycerides [mean difference 5.7 (CI 95% 0.0 to 11.4)] levels when comparing the yerba mate and control groups. According to meta-regression, differences between baseline levels could influence the findings on total cholesterol and LDL-C but not on HDL-C or triglycerides. In conclusion, this research showed that yerba mate consumption was not associated with a significant change in lipid levels. Since the results are based on small inconclusive studies, more research is needed to confirm these findings.

Effectiveness of Roux-en-Y Gastric Bypass vs Sleeve Gastrectomy on Lipid Levels in Type 2 Diabetes: a Meta-analysis.

INTRODUCTION: Obesity and its co-morbidities, including type 2 diabetes (T2DM) and dyslipidemia, are accompanied by excess cardiovascular morbi-mortality. Aside from excess low density lipoprotein-cholesterol (LDL-C), atherogenic dyslipidemia (AD), mainly characterized by elevated triglycerides and decreased high density lipoprotein-cholesterol (HDL-C) levels, is often present in T2DM obese patients. Bariatric surgery, such as Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG), has become a reference treatment in that population. However, the respective effects of RYGB vs SG on lipid metabolism in T2DM patients have been rarely studied. METHODS: A meta-analysis of randomized controlled trials, comparing the effects of RGYBG vs SG on lipid metabolism 12 months after surgery in T2DM patients, was performed. RESULTS: Four studies including a total of 298 patients (151 patients in the RYGB and 147 patients in the SG group) were examined. Despite a greater decrease in body mass index and greater improvement in glycemic control in RYGB compared to SG. RYGB vs SG was more effective in reducing total cholesterol, LDL-C, and non-HDL-C levels (mean difference [MD] -26.10 mg/dL, 95 % CI -38.88 to -13.50, p<0.00001; [MD] -20.10 mg/dL, 95 % CI -27.90 to -12.20, p<0.00001 and MD 31.90 mg/dl, 95 % CI -46.90 to -16.80, p<0.00001, respectively). CONCLUSIONS: The superiority of RYGB vs SG in reducing LDL-C, with an effect comparable to a moderate-intensity statin, suggests RYBG should be favored in hypercholesterolemic T2DM patients in order to further reduce cardiovascular risk.

Resultados: Se analizaron 345 encuestas. El 63.8% consideró la disfunción sexual como un marcador de riesgo cardiovascular. Asimismo, el 68.1% consideró relevante o muy relevante interrogar acerca de la AS. En relación con el asesoramiento, se cree que fundamentalmente lo debería comenzar el cardiólogo/a. Se observó una actitud más activa, respecto al abordaje del reinicio de la AS luego de un evento cardiovascular, un mayor interés por capacitarse en temas relacionados con la AS y una mayor solicitud de dosaje de testosterona e indicación de inhibidores de la fosfodiesterasa tipo 5 en los profesionales > 60 años y de sexo masculino en comparación con los médicos más jóvenes o de sexo femenino, respectivamente. Conclusiones: Este estudio mostró que el grado de conocimiento sobre los aspectos relacionados con la AS de los pacientes fue deficiente. Dada la relevancia del tema, consideramos importante fortalecer la educación médica en todos los ámbitos.

Low-doses aspirin in the primary prevention of cardiovascular disease in patients with diabetes: Meta-analysis stratified by baseline cardiovascular risk.

BACKGROUND AND AIM: The aim of this meta-analysis was to analyze the risks and benefits of low-dose aspirin in patients with T2D without cardiovascular conditions according to the baseline cardiovascular risk. METHODS: We performed a meta-analysis including randomized clinical trials that evaluated the use of low-dose aspirin (75-100 mg/day) versus placebo/usual care in patients with T2D. Studies were classified as low, moderate and high risk based on the number of events in the placebo/control arms or by cardiovascular risk score when reported. The incidence of MACE, cardiovascular mortality and bleeding were evaluated. RESULTS: Ten eligible trials (34069 patients) were considered eligible for the analyses. According to the stratified analysis, low-dose aspirin use was associated with reduced risk for MACE in the moderate/high-risk group (OR: 0.88; 95% CI, 0.80-0.97; I2 = 0%) but not in the low-risk group (OR: 0.89; 95% CI, 0.77-1.01; I2 = 0%). Likewise, low-dose aspirin use was associated with more bleeding in the low-risk group, showing a non-significant trend in the moderate/high-risk group. There was no reduction in cardiovascular mortality in either group. Beyond the different findings in each stratum, the differences between the subgroups were not statistically significant. CONCLUSION: This study showed that low-dose aspirin in patients with T2D reduces MACE and increases bleeding. Based on the within-subgroups results, the baseline cardiovascular risk does not modify the effect of aspirin therapy. However, few studies were included and the comparison between subgroups showed a trend in favor to the highest risk group, these results should be confirmed in future studies.
