Prediction of clinical events by liver stiffness and chronic kidney disease by NAFLD in patients with type-2 diabetes / Predicción de eventos clínicos por elasticidad hepática y enfermedad renal crónica por EHMet en pacientes con diabetes tipo 2

Background & Aims: Non-alcoholic fatty liver disease (NAFLD) is associated with poorer glycemic control and a higher risk of type-2 diabetes (T2D) complications, extrahepatic and cardiovascular disease (CVD). Our study aim was to evaluate the association between NAFLD, T2D complications, and the development of overall clinical events (OCE) (CV, liver-related, and mortality) in patients with T2D. Methods: Prospective single-center study comprising T2D subjects with no history of CVD and non-T2D matched controls. Patients were selected from the Outpatient Diabetes Clinic of Vall d’Hebron Hospital and related primary care centers. Results: 186 diabetics and 57 controls were included. Amongst T2D, 124/186 subjects had NAFLD (66.6%). T2D-NAFLD subjects showed a heavier metabolic burden and higher median liver stiffness (5.6kPa [4.5–7.3] vs 4.8 [4.2–5.8]; p=0.004) compared to non-NAFLD diabetics. During a median follow-up of 5.6 years, 33 (17.7%) T2D patients developed OCE vs 4 (7.0%) controls (p=0.049). No differences were found for OCE between NAFLD and non-NAFLD diabetics (16.9% vs 19.4%; p=0.68). CV was the most reported outcome and only one liver event occurred. NAFLD diabetics showed more often chronic kidney disease (CKD), whereas T2D complications and subclinical CVD rates were similar. A higher liver stiffness, older age, and male gender were independently associated with OCE amongst the entire T2D population and NAFLD diabetics. Conclusions: NAFLD and liver stiffness were associated with CKD and clinical outcomes in diabetics, respectively. A hepatic evaluation is recommended to identify high-risk T2D patients that would benefit from early referral to specialized care. (AU)

Antecedentes y objetivos: La esteatosis hepática metabólica (EHMet) se asocia con un peor control glucémico y un mayor riesgo de complicaciones de la diabetes tipo 2 (DM2), enfermedad extrahepática y cardiovascular (CV). El objetivo fue evaluar la asociación entre EHMet, complicaciones microvasculares y el desarrollo de eventos clínicos globales (ECG) (CV, hepáticos y mortalidad) en diabéticos. Métodos: Estudio unicéntrico prospectivo que incluye diabéticos sin historia de CV y controles sin DM2. Se seleccionaron pacientes de la consulta de Diabetes del Hospital Vall d’Hebron y centros de atención primaria asociados. Resultados: Se incluyeron 186 diabéticos y 57 controles. Entre los diabéticos, 124/186 presentaron EHMet (66,6%). Los pacientes DM2 con EHMet presentaron mayor carga metabólica y una elasticidad hepática superior (5,6kPa [4,5-7,3] vs. 4,8 [4,2-5,8]; p=0,004) a los diabéticos sin EHMet. Durante una mediana de seguimiento de 5,6 años, 33 (17,7%) diabéticos desarrollaron ECG vs. 4 (7,0%) controles (p=0,049). No hubo diferencias en ECG entre diabéticos con y sin EHMet (16,9% vs. 19,4%; p=0,68). El evento más reportado fue CV y solamente se produjo un evento hepático. La enfermedad renal crónica (ERC) fue más frecuente en diabéticos con EHMet, mientras que los ratios de complicaciones microvasculares y enfermedad CV silente fueron similares. El género masculino, una mayor edad y elasticidad hepática se asociaron de forma independiente a ECG para el total de diabéticos y para aquellos con EHMet. Conclusiones: La EHMet y la elasticidad hepática se asociaron a ERC y eventos clínicos en diabéticos. Se recomienda una evaluación hepática para identificar pacientes diabéticos de riesgo que se beneficiarían de una derivación precoz al especialista. (AU)

Spontaneous reperfusion enhances succinate concentration in peripheral blood from stemi patients but its levels does not correlate with myocardial infarct size or area at risk.

Succinate is enhanced during initial reperfusion in blood from the coronary sinus in ST-segment elevation myocardial infarction (STEMI) patients and in pigs submitted to transient coronary occlusion. Succinate levels might have a prognostic value, as they may correlate with edema volume or myocardial infarct size. However, blood from the coronary sinus is not routinely obtained in the CathLab. As succinate might be also increased in peripheral blood, we aimed to investigate whether peripheral plasma concentrations of succinate and other metabolites obtained during coronary revascularization correlate with edema volume or infarct size in STEMI patients. Plasma samples were obtained from peripheral blood within the first 10 min of revascularization in 102 STEMI patients included in the COMBAT-MI trial (initial TIMI 1) and from 9 additional patients with restituted coronary blood flow (TIMI 2). Metabolite concentrations were analyzed by 1H-NMR. Succinate concentration averaged 0.069 ± 0.0073 mmol/L in patients with TIMI flow ≤ 1 and was significantly increased in those with TIMI 2 at admission (0.141 ± 0.058 mmol/L, p < 0.05). However, regression analysis did not detect any significant correlation between most metabolite concentrations and infarct size, extent of edema or other cardiac magnetic resonance (CMR) variables. In conclusion, spontaneous reperfusion in TIMI 2 patients associates with enhanced succinate levels in peripheral blood, suggesting that succinate release increases overtime following reperfusion. However, early plasma levels of succinate and other metabolites obtained from peripheral blood does not correlate with the degree of irreversible injury or area at risk in STEMI patients, and cannot be considered as predictors of CMR variables.Trial registration: Registered at www.clinicaltrials.gov (NCT02404376) on 31/03/2015.

Extended use of dual antiplatelet therapy among older adults with acute coronary syndromes and associated variables: a cohort study.

BACKGROUND: Current guidelines recommend extending the use of dual antiplatelet therapy (DAPT) beyond 1 year in patients with an acute coronary syndrome (ACS) and a high risk of ischaemia and low risk of bleeding. No data exist about the implementation of this strategy in older adults from routine clinical practice. METHODS: We conducted a Spanish multicentre, retrospective, observational registry-based study that included patients with ACS but no thrombotic or bleeding events during the first year of DAPT after discharge and no indication for oral anticoagulants. High bleeding risk was defined according to the Academic Research Consortium definition. We assessed the proportion of cases of extended DAPT among patients 65 ≥ years that went beyond 1 year after hospitalisation for ACS and the variables associated with the strategy. RESULTS: We found that 48.1% (928/1,928) of patients were aged ≥ 65 years. DAPT was continued beyond 1 year in 32.1% (298/928) of patients ≥ 65; which was a similar proportion as with their younger counterparts. There was no significant correlation between a high bleeding risk and DAPT duration. Contrastingly, there was a strong correlation between the extent of coronary disease and DAPT duration (p < 0.001). Other variables associated with extended DAPT were a higher left ventricle ejection fraction, a history of heart failure and a prior stent thrombosis. CONCLUSION: There was no correlation between age and extended use of DAPT beyond 1 year in older patients with ACS. DAPT was extended in about one-third of patients ≥ 65 years. The severity of the coronary disease, prior heart failure, left ventricle ejection fraction and prior stent thrombosis all correlated with extended DAPT.

Coronariografía urgente en los pacientes con parada cardiaca extrahospitalaria sin elevación del segmento ST. Ensayo clínico COUPE / Coronary angiography in patients without ST-segment elevation following out-of-hospital cardiac arrest. COUPE clinical trial

Introducción y objetivos El papel de la coronariografía urgente y angioplastia, si procede, en los pacientes con parada cardiaca extrahospitalaria (PCEH) recuperada que no presentan elevación del segmento ST es controvertido. Nuestro objetivo fue evaluar si la coronariografía urgente y la angioplastia mejoran la supervivencia con buen pronóstico neurológico en esta población. Métodos En este ensayo clínico multicéntrico, aleatorizado, abierto, incluimos 69 pacientes supervivientes a una PCEH sin elevación del ST y se aleatorizaron a recibir una coronariografía urgente (CU) o diferida (CD). El objetivo primario de eficacia fue el combinado de supervivencia hospitalaria libre de dependencia. El objetivo de seguridad fue un compuesto de eventos cardiacos mayores, incluyendo muerte, reinfarto, sangrado y arritmias ventriculares. Resultados Se incluyó a 66 pacientes en el análisis primario (95,7%). La supervivencia hospitalaria fue 62,5% en el grupo CU y 58,8% en el grupo CD (HR = 0,96; IC95%, 0,45-2,09; p=0,93). La supervivencia hospitalaria con buen pronóstico neurológico fue 59,4% en el grupo CU y 52,9% en el grupo CD (HR = 1,29; IC95%, 0,60-2,73; p=0,4986). No se encontraron diferencias en los objetivos secundarios, salvo por la incidencia de fracaso renal agudo, que fue más frecuente en el grupo CU (15,6 frente a 0%, p=0,002) y de infecciones, más prevalentes en el grupo CD (46,9 frente a 73,5%, p=0,003). Conclusiones En este estudio aleatorizado de pacientes con una PCEH sin elevación del ST, una CU no fue beneficiosa en términos de supervivencia con buen pronóstico neurológico comparada con una CD (AU)

Introduction and objectives The role of emergency coronary angiography (CAG) and percutaneous coronary intervention (PCI) following out-of-hospital cardiac arrest (OHCA) in patients without ST-segment elevation myocardial infarction (STEMI) remains unclear. We aimed to assess whether emergency CAG and PCI would improve survival with good neurological outcome in this population. Methods In this multicenter, randomized, open-label, investigator-initiated clinical trial, we randomly assigned 69 survivors of OHCA without STEMI to undergo immediate CAG or deferred CAG. The primary efficacy endpoint was a composite of in-hospital survival free of severe dependence. The safety endpoint was a composite of major adverse cardiac events including death, reinfarction, bleeding, and ventricular arrhythmias. Results A total of 66 patients were included in the primary analysis (95.7%). In-hospital survival was 62.5% in the immediate CAG group and 58.8% in the delayed CAG group (HR, 0.96; 95%CI, 0.45-2.09; P=.93). In-hospital survival free of severe dependence was 59.4% in the immediate CAG group and 52.9% in the delayed CAG group (HR, 1.29; 95%CI, 0.60-2.73; P=.4986). No differences were found in the secondary endpoints except for the incidence of acute kidney failure, which was more frequent in the immediate CAG group (15.6% vs 0%, P=.002) and infections, which were higher in the delayed CAG group (46.9% vs 73.5%, P=.003). Conclusions In this underpowered randomized trial involving patients resuscitated after OHCA without STEMI, immediate CAG provided no benefit in terms of survival without neurological impairment compared with delayed CAG (AU)

Patients With High Cardiovascular Risk as Candidates to Bempedoic Acid, After Treatment With Statins, Ezetimibe and PCSK9 Inhibitors: An Estimation and Cost-Effectiveness Analysis.

ABSTRACT: Low-density lipoprotein cholesterol (LDLc) is the lead effector of atherosclerosis and main treatment target. Bempedoic acid is a novel oral drug in the therapeutic armamentarium which is able to reduce LDLc. The objectives of this study were (1) to select the potential patients for administering bempedoic acid such as those with a very high cardiovascular risk in which objectives of LDLc were not achieved despite conventional treatment with PCSK9 inhibitors (PCSK9i) and/or statins and ezetimibe and (2) to estimate the cost-effectiveness of bempedoic acid in different scenarios. The methods used were a multicenter and retrospective study of 652 patients initiating treatment with any PCSK9 inhibitor in 17 different hospitals. Before and on-treatment LDLc cholesterol levels, medical treatments, clinical indication, and baseline characteristics were recorded. The results obtained from 443 subjects in secondary prevention were analyzed. The mean (±) LDLc level at baseline was 142.5 ± 46.4 mg/dL and 61.5 ± 40.5 mg/dL in the follow-up, with a reduction of 55.9% ( P < 0.0001); 71.6% of the patients reached the target of LDL < 55 mg/dL or >50% reduction. Of those patients treated with medium-intensity and low-intensity statins plus PCSK9 inhibitors (with or without ezetimibe), only 5.7% of them were able to reduce LDL below 55 mg/dL and the main LDLc reduction in this group was the lowest (42.9% on average). Patients with TG values >135 mg/dL represented 41.6% of the sample, of which approximately 10% of them were using fibrates. Assuming only LDLc reduction and the UK price, the incremental cost-effectiveness ratio was 88,359€; 83,117€; 82,378€; and 79,015€ for different discount rates. In conclusion, one-third of the patients could achieve the target LDL proposed in the 2019 ESC/EAS guidelines. Approximately 10% of them could also benefit from treating hypertriglyceridemia as indicated in the 2021 ESC guidelines on cardiovascular disease prevention. Patients with medium-intensity and low-intensity statins plus PCSK9i and ezetimibe would be the most benefited. Bempedoic acid could be a not cost-efficacy therapy in all the scenarios, but we need to wait for the CLEAR OUTCOMES Trial results.

Prediction of clinical events by liver stiffness and chronic kidney disease by NAFLD in patients with type-2 diabetes.

BACKGROUND & AIMS: Non-alcoholic fatty liver disease (NAFLD) is associated with poorer glycemic control and a higher risk of type-2 diabetes (T2D) complications, extrahepatic and cardiovascular disease (CVD). Our study aim was to evaluate the association between NAFLD, T2D complications, and the development of overall clinical events (OCE) (CV, liver-related, and mortality) in patients with T2D. METHODS: Prospective single-center study comprising T2D subjects with no history of CVD and non-T2D matched controls. Patients were selected from the Outpatient Diabetes Clinic of Vall d'Hebron Hospital and related primary care centers. RESULTS: 186 diabetics and 57 controls were included. Amongst T2D, 124/186 subjects had NAFLD (66.6%). T2D-NAFLD subjects showed a heavier metabolic burden and higher median liver stiffness (5.6kPa [4.5-7.3] vs 4.8 [4.2-5.8]; p=0.004) compared to non-NAFLD diabetics. During a median follow-up of 5.6 years, 33 (17.7%) T2D patients developed OCE vs 4 (7.0%) controls (p=0.049). No differences were found for OCE between NAFLD and non-NAFLD diabetics (16.9% vs 19.4%; p=0.68). CV was the most reported outcome and only one liver event occurred. NAFLD diabetics showed more often chronic kidney disease (CKD), whereas T2D complications and subclinical CVD rates were similar. A higher liver stiffness, older age, and male gender were independently associated with OCE amongst the entire T2D population and NAFLD diabetics. CONCLUSIONS: NAFLD and liver stiffness were associated with CKD and clinical outcomes in diabetics, respectively. A hepatic evaluation is recommended to identify high-risk T2D patients that would benefit from early referral to specialized care.

[Environment and cardiovascular health: causes, consequences and opportunities in prevention and treatment]. / Medio ambiente y salud cardiovascular: causas, consecuencias y oportunidades en prevención y tratamiento.

The environment is a strong determinant of cardiovascular health. Environmental cardiology studies the contribution of environmental exposures with the aim of minimizing the harmful influences of pollution and promoting cardiovascular health through specific preventive or therapeutic strategies. The present review focuses on particulate matter and metals, which are the pollutants with the strongest level of scientific evidence, and includes possible interventions. Legislation, mitigation and control of pollutants in air, water and food, as well as environmental policies for heart-healthy spaces, are key measures for cardiovascular health. Individual strategies include the chelation of divalent metals such as lead and cadmium, metals that can only be removed from the body via chelation. The TACT (Trial to Assess Chelation Therapy, NCT00044213) clinical trial demonstrated cardiovascular benefit in patients with a previous myocardial infarction, especially in those with diabetes. Currently, the TACT2 trial (NCT02733185) is replicating the TACT results in people with diabetes. Data from the United States and Argentina have also shown the potential usefulness of chelation in severe peripheral arterial disease. More research and action in environmental cardiology could substantially help to improve the prevention and treatment of cardiovascular disease.

One-year cardiovascular outcomes after coronavirus disease 2019: The cardiovascular COVID-19 registry.

BACKGROUND: The long-term cardiovascular (CV) outcomes of COVID-19 have not been fully explored. METHODS: This was an international, multicenter, retrospective cohort study conducted between February and December 2020. Consecutive patients ≥18 years who underwent a real-time reverse transcriptase-polymerase chain reaction (RT-PCR) for SARS-CoV2 were included. Patients were classified into two cohorts depending on the nasopharyngeal swab result and clinical status: confirmed COVID-19 (positive RT-PCR) and control (without suggestive symptoms and negative RT-PCR). Data were obtained from electronic records, and clinical follow-up was performed at 1-year. The primary outcome was CV death at 1-year. Secondary outcomes included arterial thrombotic events (ATE), venous thromboembolism (VTE), and serious cardiac arrhythmias. An independent clinical event committee adjudicated events. A Cox proportional hazards model adjusted for all baseline characteristics was used for comparing outcomes between groups. A prespecified landmark analysis was performed to assess events during the post-acute phase (31-365 days). RESULTS: A total of 4,427 patients were included: 3,578 (80.8%) in the COVID-19 and 849 (19.2%) control cohorts. At one year, there were no significant differences in the primary endpoint of CV death between the COVID-19 and control cohorts (1.4% vs. 0.8%; HRadj 1.28 [0.56-2.91]; p = 0.555), but there was a higher risk of all-cause death (17.8% vs. 4.0%; HRadj 2.82 [1.99-4.0]; p = 0.001). COVID-19 cohort had higher rates of ATE (2.5% vs. 0.8%, HRadj 2.26 [1.02-4.99]; p = 0.044), VTE (3.7% vs. 0.4%, HRadj 9.33 [2.93-29.70]; p = 0.001), and serious cardiac arrhythmias (2.5% vs. 0.6%, HRadj 3.37 [1.35-8.46]; p = 0.010). During the post-acute phase, there were no significant differences in CV death (0.6% vs. 0.7%; HRadj 0.67 [0.25-1.80]; p = 0.425), but there was a higher risk of deep vein thrombosis (0.6% vs. 0.0%; p = 0.028). Re-hospitalization rate was lower in the COVID-19 cohort compared to the control cohort (13.9% vs. 20.6%; p = 0.001). CONCLUSIONS: At 1-year, patients with COVID-19 experienced an increased risk of all-cause death and adverse CV events, including ATE, VTE, and serious cardiac arrhythmias, but not CV death.

Medioambiente y salud cardiovascular: causas, consecuencias y oportunidades en prevención y tratamiento / Environment and cardiovascular health: causes, consequences and opportunities in prevention and treatment

El medioambiente es un gran determinante de la salud cardiovascular. La cardiología ambiental estudia la contribución de las exposiciones ambientales con el objetivo de minimizar las influencias nocivas de la contaminación y promover la salud cardiovascular mediante estrategias preventivas o terapéuticas específicas. La presente revisión se centra en el material particulado y los metales, contaminantes con la evidencia científica más sólida, e incluye las posibles intervenciones. La legislación, la mitigación y el control de los contaminantes en el aire, el agua y los alimentos y las políticas ambientales de espacios cardiosaludables son medidas clave para la salud cardiovascular. Entre las estrategias individuales, cabe reseñar la quelación de metales divalentes como el plomo y el cadmio, que solamente pueden eliminarse del cuerpo vía quelación. El ensayo clínico TACT (NCT00044213) demostró el beneficio cardiovascular en pacientes con un infarto de miocardio previo, especialmente en los diabéticos. Actualmente, el ensayo TACT2 (NCT02733185) está reproduciendo los resultados del TACT en personas con diabetes. Datos de Estados Unidos y Argentina también han mostrado la posible utilidad de la quelación en la enfermedad arterial periférica grave. Más investigación y acción en cardiología ambiental podría contribuir sustancialmente a mejorar la prevención y el tratamiento de las enfermedades cardiovasculares.(AU)

Effect of PCSK9 inhibitors on remnant cholesterol and lipid residual risk: The LIPID-REAL registry.

BACKGROUND: Monoclonal antibodies that inhibit the proprotein convertase subtilisin/kexin type 9 (PCSK9) reduce low-density lipoprotein cholesterol (LDLc) by 55%, regardless of baseline treatments. Nonetheless, the effect of other lipid parameters, such as cholesterol remnants or, the so-called lipid residual risk, is unknown. METHODS: Multicenter and retrospective registry of patients treated with PCSK9 inhibitors from 14 different hospitals in Spain. Before and on-treatment lipid parameters were recorded. Residual lipid risk was estimated by (1) cholesterol remnants, (2) triglycerides/HDLc ratio (TG/HDL), (3) total cholesterol/HDLc (TC/HDL) and (4) the triglycerides-to-glucose index (TGGi). RESULTS: Six hundred fifty-two patients were analysed, mean age of 60.2 (9.63) years, 24.69% women and mean LDLc before treatment 149.24 (49.86) mg/dl. Median time to second blood determination was 187.5 days. On-treatment LDLc was 67.46 (45.78) mg/dl, which represented a 55% reduction. Significant reductions were observed for TG/HDL ratio, cholesterol remnants, TC/HDL ratio and TGGi. As consequence, 34.61% patients had LDLc <55 mg/dl and cholesterol remnants <30 mg/dl; additionally, 31.95% had cholesterol remnants <30 mg/dl but LDLc >55 mg/dl. Patients who had levels of cholesterol remnants >30 mg/dl before initiating the treatment with PCSK9 had higher reductions in cholesterol remnants, TG/HDL ratio, TC/HDL and TGGi. By contrast, no reduction differences were observed according to baseline LDLc (< or > the mean), age, gender or obesity. CONCLUSIONS: This multicenter and retrospective registry of real-world patients treated with PCSK9 inhibitors demonstrates a positive effect on cholesterol remnants and lipid residual risk beyond LDLc reductions.

Echocardiographic assessment of COVID19 sequelae in survivors with elevated cardiac biomarkers.

AIMS: We sought to determine, using advanced echocardiography, the prevalence and type of cardiovascular sequelae after COVID19 infection with marked elevation of cardiovascular biomarkers (CVB), and their prognostic implications. METHODS: All patients admitted from March 1st to May 25th, 2020 to a tertiary referral hospital were included. Those with cardiovascular diseases or dead during admission were excluded. Patients with hs-TnI > 45 ng/L, NT-proBNP>300 pg/mL, and D-dimer >8000 ng/mL were matched with COVID controls (three biomarkers within the normal range) based on intensive care requirements and age, and separately analyzed. RESULTS: From 2025 patients, 80 patients with significantly elevated CVB and 29 controls were finally included. No differences in baseline characteristics were observed among groups, but elevated CVB patients were sicker. Follow-up echocardiograms showed no differences among groups regarding LVEF and only slight differences between groups within the normal range. Hs-TnI patients had lower myocardial work and longitudinal strain. The presence of an abnormal echocardiogram was more frequent in the elevated CVB group compared to controls (23.8 vs 10.3%, P = 0.123) but mainly associated with mild abnormalities in deformation parameters. Management did not change in any case and no major cardiovascular events except deep vein thrombosis occurred after a median follow-up of 7 months. CONCLUSION: Minimal abnormalities in cardiac structure and function are observed in COVID19 survivors without previous cardiovascular diseases who presented a significant CVB rise at admission, with no impact on patient management or short-term prognosis. These results do not support a routine screening program after discharge in this population.

Optimal opportunistic screening of atrial fibrillation using pulse palpation in cardiology outpatient clinics: Who and how.

BACKGROUND: Atrial fibrillation (AF) remain a prevalent undiagnosed condition frequently encountered in primary care. OBJECTIVE: We aimed to find the parameters that optimize the diagnostic accuracy of pulse palpation to detect AF. We also aimed to create a simple algorithm for selecting which individuals would benefit from pulse palpation and, if positive, receive an ECG to detect AF. METHODS: Nurses from four Cardiology outpatient clinics palpated 7,844 pulses according to a randomized list of arterial territories and durations of measure and immediately followed by a 12-lead ECG, which we used as the reference standard. We calculated the sensitivity and specificity of the palpation parameters. We also assessed whether diagnostic accuracy depended on the nurse's experience or on a list of clinical factors of the patients. With this information, we estimated the positive predictive values and false omission rates according to very few clinical factors readily available in primary care (age, sex, and diagnosis of heart failure) and used them to create the algorithm. RESULTS: The parameters associated with the highest diagnostic accuracy were palpation of the radial artery and classifying as irregular those palpations in which the nurse was uncertain about pulse regularity or unable to palpate pulse (sensitivity = 79%; specificity = 86%). Specificity decreased with age. Neither the nurse's experience nor any investigated clinical factor influenced diagnostic accuracy. We provide the algorithm to select the ≥40 years old individuals that would benefit from a pulse palpation screening: a) do nothing in <60 years old individuals without heart failure; b) do ECG in ≥70 years old individuals with heart failure; c) do radial pulse palpation in the remaining individuals and do ECG if the pulse is irregular or you are uncertain about its regularity or unable to palpate it. CONCLUSIONS: Opportunistic screening for AF using optimal pulse palpation in candidate individuals according to a simple algorithm may have high effectiveness in detecting AF in primary care.

Evaluation of the Use of Dual Antiplatelet Therapy beyond the First Year after Acute Coronary Syndrome.

Clinical practice guidelines recommend extending dual antiplatelet therapy (DAPT) beyond 1 year after acute coronary syndrome (ACS) in patients with high ischemic risk and without high bleeding risk. The aim of this study was to identify variables associated with DAPT prolongation in a cohort of 1967 consecutive patients discharged after ACS without thrombotic or hemorrhagic events during the following year. The sample was stratified according to whether DAPT was extended beyond 1 year, and the factors associated with this strategy were analyzed. In 32.2% of the patients, DAPT was extended beyond 1 year. Overall, 770 patients (39.1%) were considered candidates for extended treatment based on PEGASUS criteria and absence of high bleeding risk, and DAPT was extended in 34.4% of them. The presence of a PEGASUS criterion was associated with extended DAPT in the univariate analysis, but not history of bleeding or a high bleeding risk. In the multivariate analysis, a history of percutaneous coronary intervention (odds ratio (OR) = 1.8, 95% confidence interval (CI) 1.4-2.4), stent thrombosis (OR = 3.8, 95% CI 1.7-8.9), coronary artery disease complexity (OR = 1.3, 95% CI 1.1-1.5), reinfarction (OR = 4.1, 95% CI 1.6-10.4), and clopidogrel use (OR = 1.3, 95% CI 1.1-1.6) were significantly associated with extended use. DAPT was extended in 32.2% of patients who survived ACS without thrombotic or hemorrhagic events. This percentage was 34.4% when the candidates were analyzed according to clinical guidelines.

Sex Differences in Low-Density Lipoprotein Cholesterol Reduction With PCSK9 Inhibitors in Real-world Patients: The LIPID-REAL Registry.

BACKGROUND: Previous evidence supports that monoclonal antibodies that inhibit the proprotein convertase subtilisin/kexin type 9 (PCSK9) reduce low-density lipoprotein cholesterol (LDLc) by 50%-65%, regardless of baseline treatments. We tested possible sex differences in a multicentre registry of real-world patients treated with PCSK9 inhibitors. METHODS: This is a multicentre and retrospective study of 652 patients initiating treatment with any PCSK9 inhibitor in 18 different hospitals. Before-treatment and on-treatment LDLc and medical treatments, clinical indication, and clinical features were recorded. RESULTS: Women represented 24.69% of the cohort. The use of statins was similar in both sexes, but women were receiving most frequently ezetimibe. Before-treatment median LDLc was 135 (interquartile range 115-166) mg, and it was higher in women. The median on-treatment LDLc was 57 (interquartile range 38-84) mg/dL, which represented a mean 54.5% reduction. On-treatment LDLc was higher in women, and the mean LDLc reduction was lower in women (47.4% vs. 56.9%; P = 0.0002) receiving evolocumab or alirocumab. The percentage of patients who achieved ≥50% LDLc reduction was higher in men (71.36% vs. 57.62%; P = 0.002). According to LDLc before-treatment quartiles, LDLc reduction was statistically lower in women in the 2 highest and a significant interaction of women and baseline LDLc >135 mg/dL was observed. Women were negatively associated with lower rates of LDLc treatment target achievement (odds ratio: 0.31). Differences were also observed in women with body mas index >25 kg/m2. Only 14 patients (2.14%) presented side effects. CONCLUSIONS: This multicentre and retrospective registry of real-world patients treated with PCSK9 inhibitors highlights significant gender differences in LDLc reduction.
