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.

Heart Failure in the Elderly: the Role of Biological and Sociocultural Aspects Related to Sex.

PURPOSE OF REVIEW: Heart failure (HF) entails poor prognosis, with high morbidity and mortality burden, particularly in elderly patients. Notably, important sex differences have been described between men and women with HF. In this regard, some biological and sociocultural aspects related to sex may play a key role in the different development and prognosis of HF in elderly men and women. RECENT FINDINGS: Important differences between men and women with HF, especially in the elderly population, have been specifically addressed in recent studies. Consequently, specific differences in biological and sociocultural aspects have been found to associate differences in pathophysiology, baseline clinical profile, and prognosis according to sex. Moreover, differences in comorbidities and frailty and other geriatric conditions, frequent in elderly population with HF, have also been described. Biological and sociocultural differences related to sex are key in the different clinical presentation and prognosis of heart failure in elderly women. Further studies will be required to better understand some other underlying reasons that may differently impact prognosis in elderly patients with HF.

Efficacy and Safety of Loading Doses With P2Y12-Receptor Antagonists in Patients Without Dual Antiplatelet Therapy Undergoing Elective Coronary Intervention.

BACKGROUND: European Guidelines on Myocardial Revascularization recommend clopidogrel loading dose added to acetylsalicylic acid in elective percutaneous coronary interventions (PCIs). However, there is few evidence supporting this recommendation and other P2Y12 inhibitors have not been tested in these patients. PURPOSE: To evaluate the effectiveness and safety of different loading doses of clopidogrel and ticagrelor in patients without double antiplatelet therapy and stable coronary artery disease (SCAD) undergoing elective PCI. METHODS: Retrospective study of 147 consecutive patients with SCAD undergoing elective PCI. Loading P2Y12 inhibitor doses evaluated were: clopidogrel 600 mg, clopidogrel 300 mg, clopidogrel 150 mg, and ticagrelor 180 mg. We analyzed the occurrence of major adverse cardiovascular events and periprocedural myocardial infarction. RESULTS: One hundred twenty-five patients were treated with clopidogrel (16 with clopidogrel 150 mg, 7 with clopidogrel 300 mg, and 93 with clopidogrel 600 mg) and 21 with ticagrelor 180 mg at the catheterization laboratory. The ticagrelor group had a significantly lower postprocedural peak of troponin-I (0.7 ± 3.4 vs. 0.3 ± 0.7 ng/mL; P = 0.02). There were no differences between groups in terms of major bleeding and hemoglobin drop after PCI (0.6 ± 0.8 vs. 4 ± 0.6; P = 0.8). The median of follow-up was 17 months (interquartile range 9-32.7). At the end of follow-up, major adverse cardiovascular event rate was not different between groups. CONCLUSIONS: In patients without dual antiplatelet therapy undergoing elective PCI, the use of ticagrelor showed lower postprocedural myocardial injury without more bleeding complications.

No sólo a la cocaína teme el miocardio / Cocaine not only fears the myocardium

Resumen Los eventos cardiovasculares asociados al consumo de heroína son infrecuentes y se relacionan con la vía intravenosa. Se presenta un caso de un varón de 39 años, consumidor de heroína inhalada, que sufrió un infarto de miocardio evolucionado. El cateterismo coronario reflejó una oclusión subaguda de la arteria descendente anterior, que requirió implante de un stent farmacoactivo. Algunos estudios observacionales retrospectivos sugieren que el consumo de opiáceos por vía oral o inhalada incrementa el riesgo de enfermedad coronaria e infarto, de ahí la importancia de la prevención cardiovascular en este grupo de pacientes.

Abstract The cardiovascular events associated with heroin use are uncommon, and related to intravenous use. A case of a 39-year-old male is presented, a consumer of inhaled heroin, who suffered an evolving myocardial infarction. The coronary catheterisation showed a sub-acute occlusion of the anterior descending artery, which required a drug-eluting stent. Some retrospective observational studies suggest the consumption of opiates by the oral or inhaled route increases the risk of coronary disease and infarction, as well as the importance of cardiovascular prevention in this patient group.

Chlorambucil-induced cytomegalovirus infection: a case report.

INTRODUCTION: Chlorambucil is an alkylating agent used in combination with prednisolone for the treatment of idiopathic membranous nephropathy. Although chlorambucil is generally well-tolerated, it is a myelosuppresive drug that can cause several infections. CASE PRESENTATION: We report the case of an 81-year-old Caucasian male presenting with idiopathic membranous nephropathy who developed fever, cough, dyspnea, pulmonary infiltrates, and abdominal pain shortly after the initiation of treatment with chlorambucil and corticosteroids for nephropathy. Virology tests for infectious diseases revealed a recent cytomegalovirus infection. Antiviral treatment (ganciclovir) resulted in full remission. CONCLUSIONS: Cytomegalovirus infection should be considered in the differential diagnosis of respiratory symptoms and pulmonary infiltrates in patients treated with chlorambucil for nephrotic syndrome.
