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.

Statins and new-onset diabetes in primary prevention setting: an updated meta-analysis stratified by baseline diabetes risk.

AIMS: The use of statins has been associated with an increased risk of new-onset diabetes. The characteristics of the population could influence this association. The objective of this study was to determine the risk of new-onset diabetes with the use of statins in patients in primary prevention, with an assessment of the results according to the baseline risk of developing diabetes of the included population. METHODS: We performed an updated meta-analysis including randomized trials of statin therapy in primary prevention settings that report new-onset diabetes. The rate of new cases of diabetes in the control arms was estimated for each study. The studies were classified into two groups (low rate: < 7.5 events per 1000 patients-year; high rate; ≥ 7.5 events per 1000 patients-year). The fixed-effects model was performed. RESULTS: Eight studies (70,453 patients) were included. Globally, statin therapy was associated with an increased risk of new-onset diabetes (OR 1.1; 95% CI 1.0-1.2, I2 35%). When we analyzed the studies according to the baseline diabetes risk in the control groups, the results showed that there was a greater risk only in the studies with a high baseline rate (OR 1.2; 95% CI 1.1-1.3, I2 0%; interaction p value = 0.01). CONCLUSION: Globally, the use of statins in patients in primary prevention was associated with an increased risk of new-onset diabetes. In the stratified analysis, this association was observed only in the group of studies with a high baseline rate of events.

Dyslipidemia in adults with congenital heart disease: A systematic review and meta-analysis.

AIMS: Several particular characteristics of patients with congenital heart disease could affect lipid levels. The objectives of this study were: a) to analyze the prevalence of dyslipidemia in congenital heart disease patients; 2) to compare lipid levels between congenital heart disease patients and a control group. DATA SYNTHESIS: This systematic review and meta-analysis was performed according to PRISMA guidelines (PROSPERO CRD42023432041). A literature search was performed to detect studies that have reported lipid levels or the prevalence of dyslipidemia in congenital heart disease patients. We performed a qualitative analysis (studies that reported dyslipidemia prevalence) and quantitative analysis (studies that compared lipid values between congenital heart disease patients and controls). In total, 29 observational studies involving 22,914 patients with congenital heart disease and 641,086 controls were eligible for this review. The reported presence of "hyperlipidemia" or "dyslipidemia" ranged from 14.3% to 69.9%. When studies analyzed lipid variables dichotomously between congenital heart disease patients and controls, the results were conflicting. The quantitative analysis showed that patients with congenital heart disease have lower levels of total cholesterol (MD: -18.9 [95% CI: -22.2 to -15.7]; I2 = 93%), LDL-C (MD: -10.7 [95% CI: -13.1 to -8.3]; I2 = 90%) and HDL-C (MD: -6.3 [95% CI: -7.7 to -4.9]; I2 = 95%) compared to controls. CONCLUSIONS: The qualitative analysis showed some concerns, but the quantitative analysis indicates that congenital heart disease patients showed lower levels of total cholesterol, LDL-C, and HDL-C compared to controls. New research should be developed to clarify this relevant topic.

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.

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 of Subclinical Hypothyroidism on Epicardial Adipose Tissue: A Systematic Review and Meta-Analysis.

Accumulation of epicardial adipose tissue (EAT) and Subclinical hypothyroidism (SH) are associated with increased cardio-metabolic risk. The objective of this study was to quantitatively compare EAT thickening between patients with SH and healthy controls. Therefore, after searching the PubMed/MEDLINE, Embase, Science Direct, Scopus, Google Scholar, and Cochrane databases; we analyzed a group of observational studies who compare the EAT changes between SH vs control groups. A total of 9 studies were included in the final analysis, for a total of 424 patients with SH and 330 controls. Random or fixed effects models were used. Pooled analysis revealed that HS increased EAT (MD: 1.0 mm [0.40; 1.50]; P < 0.01). This meta-analysis suggests that the amount of EAT is significantly increased in SH patients. EAT might be a marker of cardiovascular risk in patients with SH.

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.

[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.

Niveles elevados de lipoproteína (a) y riesgo de eventos clínicos relacionados con la estenosis valvular aórtica: una revisión sistemática / High Lipoprotein(a) Levels and Risk of Aortic Valve Stenosis Related Clinical Events: A Systematic Review

RESUMEN Introducción: Varios estudios han evaluado la asociación entre los niveles plasmáticos de lipoproteína (a) [Lp(a)] y la aparición de eventos relacionados con la estenosis valvular aórtica, aunque los resultados fueron contradictorios. Objetivo: El objetivo de esta revisión fue analizar la capacidad predictiva de los niveles elevados de Lp(a) sobre los eventos clínicos relacionados con la estenosis valvular aórtica. Material y métodos: Esta revisión sistemática se realizó de acuerdo con las recomendaciones PRISMA y STROBE. Se realizó una búsqueda en diferentes bases de datos con el objetivo de identificar estudios de cohorte que evaluaran la asociación entre los niveles de Lp(a) y los eventos de interés. El punto final primario fue la incidencia de eventos clínicos relacionados con la estenosis aórtica (reemplazo valvular aórtico, muerte u hospitalización). Esta revisión fue registrada en PROSPERO. Resultados: Se consideraron elegibles para el análisis siete estudios observacionales con un total de 58 783 pacientes. Los valores elevados de Lp(a) se asociaron con un mayor riesgo de eventos relacionados con la estenosis valvular aórtica en la mayoría de los estudios evaluados (entre un 70% y aproximadamente 3 veces más riesgo), a pesar de ajustar por otros factores de riesgo. Conclusión: Esta revisión sugiere que los niveles elevados de Lp(a) se asocian con una mayor incidencia de eventos clínicos relacionados con la estenosis valvular aórtica. Sin embargo, y considerando las limitaciones de este estudio, la utilidad clínica de la Lp(a) como marcador pronóstico en la enfermedad valvular aórtica deberá confirmarse en futuras investigaciones.

ABSTRACT Background: Several studies have evaluated the association between lipoprotein(a) plasma levels [Lp(a)] and the occurrence of aortic valve stenosis related events, with contradictory results. Objective: The main objective of this systematic review was to analyze the predictive capacity of elevated Lp(a) levels on major clinical events associated with aortic valve stenosis. Methods: This systematic review was conducted in accordance with PRISMA and STROBE recommendations. A search was carried out in order to identify studies with a cohort design evaluating the association between Lp(a) levels and the events of interest. The primary endpoint was the incidence of clinical events related with aortic valve stenosis (aortic valve replacement, death or hospitalization). This review was registered in PROSPERO. Results: Seven observational studies with a total of 58 783 patients were eligible for analysis. Our findings showed that the presence of elevated Lp(a) levels was associated with an increased risk of events related with aortic valve stenosis in most of the studies evaluated (between 70% and approximately 3-fold higher risk), despite adjusting for other risk factors. Conclusion: This review suggests that elevated Lp(a) levels are associated with a higher incidence of aortic valve stenosis related clinical events. However, considering the limitations of this study, the clinical usefulness of Lp(a) as a prognostic marker in aortic valve disease should be confirmed in future investigations.

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.

Effect of glucagon-like peptide-1 (GLP-1) analogues on epicardial adipose tissue: A meta-analysis.

BACKGROUND AND AIMS: Glucagon-like peptide-1 (GLP-1) analogues reduce body fat and cardiovascular events in patients with type 2 diabetes. Accumulation of epicardial adipose tissue (EAT) is associated with increased cardio-metabolic risks and coronary events in type 2 diabetes. METHODS: A systematic review and meta-analysis were performed from Glucagon-like peptide-1 analogues therapy on type 2 diabetes patients, reporting data from changes in EAT, after searching the PubMed/MEDLINE, Embase, Science Direct, Scopus, Google Scholar, and Cochrane databases. RESULTS: It has been found a limited number of studies, a total of 4 studies (n = 160 patients with GLP-1 analogues therapy) were included in the final analysis. Pooled analysis revealed that GLP-1 analogues reduce EAT (MD: 1.83 mm [-2.50; -1.10]; P < 0.01). Compared with the patients before the treatment, the patients after the treatment had a smaller HbA1c (MD -1.10%[-1.80; -0.30]; p = 0.0143) and body mass index was reduced (MD -2.20 kg/m2[-3.70; -0.60]; p = 0.0058), GLP-1 therapy reduced low-density lipoprotein levels (MD-13.53 mg/dL [-21.74; -5.31]; p = 0.001) and reduced triglycerides levels significantly (MD -18.32 -28.20 mg/dL; -8.50); p = 0.0003). CONCLUSIONS: This meta-analysis suggests that the amount of EAT is significantly reduced in T2D patients with Glucagon-like peptide-1 analogues.

Hemostatic Efficacy of Absorbable Gelatin Sponges for Surgical Nail Matrixectomy after Phenolization-A Blinded Randomized Controlled Trial.

Background: Some studies have recommended combining germinal matrix excision with phenol ablation in the treatment of onychocryptosis. Matrixectomy after phenolization has been shown to be an effective modification to reduce the drawbacks associated with phenolization alone, although it increases the risk of minor postoperative bleeding. The present study aims to assess the effectiveness and safety of gelatin sponges as hemostatic agents in partial matrixectomy after phenolization. Methods: A comparative clinical trial in parallel groups was designed in 74 halluces (44 patients) with stage I, II, and III onychocryptosis. All participants were randomly assigned to 3 groups: Group A (control group), Group B (conventional gelatin sponge), and Group C (high porosity gelatin sponge). Results: The quantified mean blood loss in the first 48 h after surgery in patients in both experimental groups was significantly lower compared to the control group. The lowest mean blood loss was recorded in Group C (p < 0.001) and followed by Group B (p = 0.005). No adverse effects were recorded in any of the patients included in the experimental groups. Conclusions: Hemostatic gelatin sponges were demonstrated to be effective and safe devices for the control of minor postoperative bleeding associated with matrixectomy after segmental phenolization.

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.

Elevated lipoprotein (a) levels and risk of peripheral artery disease outcomes: A systematic review.

BACKGROUND: Despite strong association of elevated lipoprotein (a) (Lp(a)) levels with incident coronary and cerebrovascular disease, data for incident peripheral artery disease (PAD) are less robust. The main objective of the present systematic review was to analyze the association between elevated Lp(a) levels and PAD outcomes. METHODS: This systematic review was performed according to PRISMA guidelines. A literature search was performed to detect randomized clinical trials or observational studies with a cohort design that evaluated the association between Lp(a) levels and PAD outcomes. RESULTS: Fifteen studies including 493,650 subjects were identified and considered eligible for this systematic review. This systematic review showed that the vast majority of the studies reported a significant association between elevated Lp(a) levels and the risk of PAD outcomes. The elevated Lp(a) levels were associated with a higher risk of incident claudication (RR: 1.20), PAD progression (HR: 1.41), restenosis (HR: 6.10), death and hospitalization related to PAD (HR: 1.37), limb amputation (HR: 22.75), and lower limb revascularization (HR: 1.29 and 2.90). In addition, the presence of elevated Lp(a) values were associated with a higher risk of combined PAD outcomes, with HRs in a range between 1.14 and 2.80, despite adjusting for traditional risk factors. Heterogeneity of results can be explained by different patient populations studied and varying Lp(a) cut-off points of Lp(a) analyzed. CONCLUSION: This systematic review suggests that evidence is available to support an independent positive association between Lp(a) levels and the risk of future PAD outcomes. PROSPERO Registration No.: 289253.

Prognostic role of cardiopulmonary exercise testing in pulmonary hypertension: a systematic review and meta-analysis.

INTRODUCTION: Several studies have evaluated the relation between variables of cardiopulmonary exercise testing (CPET) and major clinical events in pulmonary hypertension (PH) patients, although the results were conflicting. The main objective of this study was to investigate the prognostic value of the CPET derived parameters on all-cause mortality or urgent transplantation in PH patients. MATERIAL AND METHODS: A meta-analysis of time-to-event outcomes were performed from observational studies that evaluated the predictive value of CEPT-related variables [peak oxygen uptake (VO2) and the ventilation to CO2 production slope (VE/VCO2)] in PH patients, reporting data from mortality or urgent transplantation, after searching the PubMed/MEDLINE, Embase, Science Direct, Scopus, Google Scholar, and Cochrane databases. A random-effects meta-analysis model was then applied. RESULTS: Nine eligible studies, including 986 patients, were identified and considered eligible for the quantitative analyses. This meta-analysis showed that high peak VO2 was associated with a lower mortality or transplant occurrence (HR: 0.81; 95% CI: 0.78-0.85, I2 = 29%). In addition, high VE/VCO2 slope was associated with a higher incidence of the primary endpoint (HR: 1.04; 95% CI: 1.02-1.06, I2 = 78%). The sensitivity analysis showed that the results were robust. CONCLUSIONS: Our data suggest that in a population with PH the CPET-related variables have predictive capacity regarding mortality and the risk of transplantation. Future studies should establish the best cut-off points for these CPET-related variables.

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.
