Influence of sex on the timing of coronary angiography and the prescription of antiplatelet therapy in patients with nonST-segment elevation myocardial infarction. / Impacto del sexo en los tiempos de cateterismo y en el uso de pretratamiento antiagregante plaquetario en pacientes con síndrome coronario agudo sin elevación del segmento ST (SCASEST).

OBJECTIVES: To assess differences in the clinical management of nonST-segment elevation myocardial infarction (NSTEMI), including in-hospital events, according to biological sex. MATERIAL AND METHODS: Prospective observational multicenter study of patients diagnosed with NSTEMI and atherosclerosis who underwent coronary angiography. RESULTS: We enrolled 1020 patients in April and May 2022; 240 (23.5%) were women. Women were older than men on average (72.6 vs 66.5 years, P .001), and more women were frail (17.1% vs 5.6%, P .001). No difference was observed in pretreatment with any P2Y12 inhibitor (prescribed in 68.8% of women vs 70.2% of men, P = .67); however, more women than men were prescribed clopidogrel (56% vs 44%, P = .009). Women prescribed clopidogrel were more often under the age of 75 years and not frail. Coronary angiography was performed within 24 hours less corooften in women (29.8% vs 36.9%, P = .03) even when high risk was recognized. Frailty was independently associated with deferring coronary angiography in the adjusted analysis; biological sex by itself was not related. The frequency and type of revascularization were the same in both sexes, and there were no differences in in-hospital cardiovascular events. CONCLUSION: Women were more often prescribed less potent antithrombotic therapy than men. Frailty, but not sex, correlated independently with deferral of coronary angiography. However, we detected no differences in the frequency of coronary revascularization or in-hospital events according to sex.

OBJETIVO: Evaluar las diferencias en el manejo clínico y eventos intrahospitalarios en una cohorte de pacientes con síndrome coronario agudo sin elevación del segmento ST (SCASEST) en función del sexo. METODO: Estudio observacional, prospectivo y multicéntrico que incluyó pacientes consecutivos con diagnóstico de SCASEST sometidos a coronariografía con enfermedad ateroesclerótica responsable. RESULTADOS: Entre abril y mayo de 2022 se incluyeron 1.020 pacientes; de ellos, 240 eran mujeres (23,5%). En comparación con los hombres, las mujeres fueron mayores (72,6 años vs 66,5 años; p 0,001) y más frágiles (17,1% vs 5,6%; p 0,001). No hubo diferencias en el pretratamiento con un inhibidor del receptor P2Y12 (68,8% vs 70,2%, p = 0,67), aunque las mujeres recibieron más pretratamiento con clopidogrel (56% vs 44%, p = 0,009), principalmente aquellas de edad 75 años y sin fragilidad. En las mujeres se realizaron menos coronariografías precoces (# 24 h) (29,8% vs 36,9%; p = 0,03) a pesar de presentar la misma indicación (criterios de alto riesgo). En el análisis ajustado, la fragilidad, pero no el sexo, se asoció de forma independiente con la realización de una coronariografía diferida. La tasa y el tipo de revascularización fue igual en ambos sexos, y no hubo diferencias en los eventos cardiovasculares intrahospitalarios. CONCLUSIONES: Las mujeres recibieron con mayor frecuencia un tratamiento antitrombótico menos potente. La fragilidad y no el sexo se asoció con la realización de coronariografía diferida. Sin embargo, no hubo diferencias en la tasa de revascularización coronaria ni en los eventos intrahospitalarios en función del sexo.

Tiempos de cateterismo y uso de pretratamiento antiagregante plaquetario en pacientes con SCASEST en España / Timing of coronary angiography and use of antiplatelet pretreatment in patients with NSTEACS in Spain

Introducción y objetivos El momento óptimo para un cateterismo en el síndrome coronario agudo sin elevación del segmento ST (SCASEST) y la necesidad de pretratamiento son motivo de controversia. El objetivo principal del registro IMPACT-TIMING-GO es conocer el porcentaje de pacientes examinados con una coronariografía precoz (0-24 h) y que no recibieron doble antiagregación plaquetaria antes del cateterismo (estrategia sin pretratamiento) en España. Métodos Estudio observacional, prospectivo y multicéntrico, que incluyó a pacientes consecutivos con diagnóstico de SCASEST sometidos a cateterismo en los que se evidenció enfermedad coronaria ateroesclerótica causal. Resultados Entre abril y mayo de 2022 se incluyó a 1.021 pacientes (media de edad, 67±12 años; el 23,6% mujeres). El 86,8% de los pacientes cumplían criterios de alto riesgo (elevación de troponina, cambios electrocardiográficos o puntuación GRACE>140); sin embargo, únicamente el 37,8% se sometió a una estrategia invasiva precoz, y el 30,3% no recibió pretratamiento. Globalmente, solo el 13,6% de los pacientes se sometieron a una estrategia invasiva precoz sin un segundo antiagregante plaquetario, y la estrategia diferida con pretratamiento fue la más utilizada (46%). Durante el ingreso, 9 pacientes (0,9%) fallecieron y 34 (3,3%) presentaron una hemorragia grave. Conclusiones En España, solo el 13,6% de los pacientes con SCASEST sometidos a cateterismo reciben una estrategia invasiva precoz sin pretratamiento. La incidencia de eventos cardiovasculares y hemorragias graves en el ingreso es baja. (AU)

Introduction and objectives The optimal timing of coronary angiography in patients admitted with non–ST-segment elevation acute coronary syndrome (NSTEACS) as well as the need for pretreatment are controversial. The main objective of the IMPACT-TIMING-GO registry was to assess the proportion of patients undergoing an early invasive strategy (0-24hours) without dual antiplatelet therapy (no pretreatment strategy) in Spain. Methods This observational, prospective, and multicenter study included consecutive patients with NSTEACS who underwent coronary angiography that identified a culprit lesion. Results Between April and May 2022, we included 1021 patients diagnosed with NSTEACS, with a mean age of 67±12 years (23.6% women). A total of 87% of the patients were deemed at high risk (elevated troponin; electrocardiogram changes; GRACE score>140) but only 37.8% underwent an early invasive strategy, and 30.3% did not receive pretreatment. Overall, 13.6% of the patients underwent an early invasive strategy without pretreatment, while the most frequent strategy was a deferred angiography under antiplatelet pretreatment (46%). During admission, 9 patients (0.9%) died, while major bleeding occurred in 34 (3.3%). Conclusions In Spain, only 13.6% of patients with NSTEACS undergoing coronary angiography received an early invasive strategy without pretreatment. The incidence of cardiovascular and severe bleeding events during admission was low. (AU)

Infarto agudo de miocardio prematuro con elevación del segmento ST: análisis de una cohorte en la década 2012-2022 / Premature acute myocardial infarction with ST segment elevation: a cohort study in the 2012-2022 decade

Resumen Antecedentes y objetivo: El infarto prematuro tiene un alto impacto socioeconómico y carecemos de estudios contemporáneos que analicen las características asociadas al desarrollo de estos eventos y a su evolución Material y meéodos: En un estudio observacional sobre una cohorte retrospectiva que incluyó pacientes menores de 46 años con un infarto entre junio de 2012 y junio de 2022, se analizaron las características sociodemográficas, factores de riesgo cardiovasculares, tóxicos, características del infarto, datos sobre infección e inmunización por SARS-CoV-2, se realizó un seguimiento retrospectivo a un anÌo mediante la historia electrónica y se compararon los resultados con los reportados en la literatura. Resultados: El 12.1% de las angioplastias primarias corresponded a infartos prematuros (103). Entre los factores de riesgo clásicos destacaron la dislipidemia y el sobrepeso. La hipertensión y la diabetes fueron significativamente menores que las cifras reportadas en población mayor. El consumo de tabaco fue significativamente mayor, aí como el de otros tóxicos entre los que destacaron el cannabis y la ocaína. Los antecedentes familiares estuvieron presentes en 27 pacientes. El 27.2% (28) tuvieron complicaciones durante el ingreso y la mortalidad fue del 4.9% (5). No se identificaron diferencias significativas entre los pacientes que iniciaron con un evento antes o despuéde la pandemia, a excepción de una tendencia a la disminción del hábito tabáquico. Conclusiones: El infarto prematuro es una patología al alza con una morbimortalidad considerable. La concienciación sobre los hábitos tóxicos y prevención de los factores de riesgo clásicos son tareas prioritarias en nuestro medio.

Abstract Background and purpose: Premature infarction has a high socioeconomic impact and we lack contemporary studies that analyze the characteristics associated with its development and evolution. Material and methods: In an observational study on a retrospective cohort of patients younger than 46 years old, who had suffered from an infarction from June 2012 to June 2022, sociodemographic characteristics, cardiovascular and toxic risk factors, infarction characteristics, SARS-CoV-2 infection and immunization data were investigated. Indeed, a one-year retrospective follow-up was performed through their electronic health record and results were compared with the ones reported in literature. Results: 12.1% of primary angioplasties corresponded to premature infarctions (103). Among classical risk factors, dyslipidemia and overweight stood out, while hypertension and diabetes incidence was significantly lower than the one reported in older population. The consumption of tobacco and other drugs (especially cannabis and cocaine) was higher than that reported at older ages. Twenty-seven patients had a family history of ischemic cardiopathy or sudden cardiac death, 27.2% (28) had complications during admission and mortality was 4.9% (5). No significant differences were identified between the patients who debuted with an event before or after the pandemic, except for a tendency to smoking cessation. Conclusions: Premature infarction is a rising pathology with considerable morbidity and mortality. Raising awareness about toxic habits and prevention of the classical risk factors are priority tasks in this setting.

Long-term outcomes of extended DAPT in a real-life cohort of consecutive STEMI patients.

INTRODUCTION AND OBJECTIVES: Dual antiplatelet therapy (DAPT) duration after ST-segment elevation myocardial infarction (STEMI) remains a matter of debate. METHODS: We analyzed the effect of DAPT on 5-year all-cause mortality, cardiovascular mortality, and cardiovascular readmission or mortality in a cohort of 1-year survivor STEMI patients. RESULTS: A total of 3107 patients with the diagnosis of STEMI were included: 93% of them were discharged on DAPT, a therapy that persisted in 275 high-risk patients at 5 years. Cardiovascular mortality in patients on single antiplatelet therapy vs DAPT at 5 years was 1.4% vs 3.6% (P <.01), respectively, whereas noncardiovascular mortality was 3.3% vs 5.8% (P=.049) at 5 years. Cardiovascular readmission or mortality in patients with single antiplatelet therapy vs DAPT was 11.4% vs 46.5% (P <.001). Extended DAPT was independently associated with worse 5-year all-cause mortality (HR, 2.16; 95%CI, 1.40-3.33), cardiovascular mortality (HR, 2.83; 95%CI, 1.37-5.84), and cardiovascular readmission or mortality (HR, 5.20; 95%CI, 3.96-6.82). These findings were confirmed in propensity score matching and inverse probability weighting analyses. CONCLUSIONS: Our results suggest the hypothesis that, in 1-year STEMI survivors, extending DAPT up to 5 years in high-risk patients does not improve their long-term prognosis.

Benefit of primary percutaneous coronary interventions in the elderly with ST segment elevation myocardial infarction.

OBJECTIVE: Primary percutaneous coronary intervention (P-PCI) has demonstrated its efficacy in patients with ST segment elevation myocardial infarction (STEMI). However, patients with STEMI ≥75 years receive less P-PCI than younger patients despite their higher in-hospital morbimortality. The objective of this analysis was to determine the effectiveness of P-PCI in patients with STEMI ≥75 years. METHODS: We included 979 patients with STEMI ≥75 years, from the ATención HOspitalaria del Síndrome coronario study, a registry of 8142 consecutive patients with acute coronary syndrome admitted at 31 Spanish hospitals in 2014-2016. We calculated a propensity score (PS) for the indication of P-PCI. Patients that received or not P-PCI were matched by PS. Using logistic regression, we compared the effectiveness of performing P-PCI versus non-performance for the composite primary event, which included death, reinfarction, acute pulmonary oedema or cardiogenic shock during hospitalisation. RESULTS: Of the included patients, 81.5 % received P-PCI. The matching provided two groups of 169 patients with and without P-PCI. Compared with its non-performance, P-PCI presented a composite event OR adjusted by PS of 0.55 (95% CI 0.34 to 0.89). CONCLUSIONS: Receiving a P-PCI was significantly associated with a reduced risk of major intrahospital complications in patients with STEMI aged 75 years or older.

Dexmedetomidine in medical cardiac intensive care units. Data from a multicenter prospective registry.

BACKGROUND: Dexmedetomidine induces cooperative and arousable sedation. Our aim was to analyze dexmedetomidine use in medical cardiac intensive care units (CICU). METHODS: Multicenter prospective registry of patients treated with dexmedetomidine in CICU. Consecutive inclusion during a 12-month period. RESULTS: A total of 410 patients were included, mean age was 67.4 ± 13.9 years, and 94 (22.9%) were women. Before using dexmedetomidine, 247 patients (60.2%) had delirium, 48 developed delirium after dexmedetomidine use. In 178 (43.4%) dexmedetomidine was used during weaning from mechanical ventilation, with a reintubation rate of 10.1%, early reintubation rate (<24 h) 1.7%. Seventy-seven patients (18.8%) died during admission. Dexmedetomidine mean dose infusion was 0.51 ± 0.25 µ/kg/h, during a median of 34 h (interquartile range 12-78 h). Three hundred forty-eight patients received adjuvant sedatives (84.9%). Sixty-eight patients (16.6%) had adverse effects. The most frequent adverse effects were hypotension with systolic blood pressure <80 mmHg (44 patients - 10.7%), bradycardia <40 beats per minute (15 patients - 3.7%), and both bradycardia and hypotension (4 patients - 1.0%). Patients with adverse effects received more frequently inotropes (53 [81.6%] vs. 212 [65.4%], p = 0.02) and fewer adjuvant sedatives (49 [75.4%] vs. 282 [87.0%], p = 0.01). The independent predictors of adverse effects were inotropes use (odds ratio [OR] 2.73, 95% confidence interval [CI] 1.30-5.74, p = 0.008) and lack of adjuvant sedatives (OR 3.03, 95% CI 1.49-6.26, p = 0.002). CONCLUSION: Dexmedetomidine safety for medical CICU patients seems to be similar to that for general intensive care unit patients. Inotropes and lack of adjuvant sedatives were associated with adverse effects.
