Predictores del uso de la estrategia invasiva precoz en mujeres con síndrome coronario agudo sin elevación de ST / Predictors of the use of the early invasive strategy in women with non-ST-elevation acute coronary syndrome

OBJETIVO: Identificar los determinantes asociados a la estrategia invasiva precoz (EIP) en mujeres con síndrome coronario agudo sin elevación de ST (SCASEST). DISEÑO: Estudio de cohortes retrospectivo. Análisis crudo y ajustado de la realización de EIP mediante regresión logística no condicional. Ámbito: Unidades coronarias participantes en 2010-2011 en el registro ARIAM-SEMICYUC. PACIENTES: Cuatrocientas cuarenta mujeres con SCASEST. Se excluyeron 16 por datos insuficientes y 58 con coronariografía electiva (> 72 h). Variables analizadas: Demográficas, factores de riesgo coronario, medicación previa, comorbilidad. Características clínicas, analíticas, hemodinámicas y electrocardiográficas del episodio. RESULTADOS: Las mujeres tratadas conservadoramente presentaban mayor edad, mayor prevalencia de anticoagulación oral, diabetes, lesiones coronarias previas e insuficiencia cardiaca (p < 0,005), mayor riesgo hemorrágico e isquémico basal (p = 0,05) y mayor frecuencia cardiaca al ingreso (p < 0,05). Tras el ajuste solo la edad mayor de 80 años (OR: 0,48; IC 95%: 0,27-0,82; p = 0,009), las lesiones coronarias conocidas (OR: 0,47; IC 95%: 0,26-0,84, p = 0,011) y la frecuencia cardiaca (OR: 0,98; IC 95%: 0,97-0,99, p = 0,003) se asociaron de forma independiente al tratamiento conservador. El tabaquismo (OR: 2,50; IC 95%: 1,20-5,19; p = 0,013) y el electrocardiograma de alto riesgo (OR: 2,96; IC 95%: 1, 72-4,97; p < 0,001) se asociaron a la EIP. La exclusión de muertes precoces (< 24 h) no alteró estos resultados. CONCLUSIONES: En mujeres con SCASEST el tabaquismo y el electrocardiograma de alto riesgo al ingreso son factores independientes asociados a la EIP. Las lesiones coronarias previas conocidas, la edad > 80 años y el aumento de la frecuencia cardiaca son factores independientes asociados al tratamiento conservador

OBJECTIVE: To identify determinants associated to an early invasive strategy in women with acute coronary syndromes without ST elevation (NSTE-ACS). DESIGN: A retrospective cohort study was made. Crude and adjusted analysis of the performance of the early invasive strategy using logistic regression. SETTING: Coronary Units enrolled in 2010 - 2011 in the ARIAM-SEMICYUC registry. PATIENTS: A total of 440 women with NSTE-ACS were studied. Sixteen patients were excluded due to insufficient data, together with 58 patients subjected to elective coronary angiography (> 72h). Variables analyzed: Demographic parameters, coronary risk factors, previous medication, comorbidity. Clinical, laboratory, hemodynamic and electrocardiographic data of the episode. RESULTS: Women treated conservatively were of older age, had oral anticoagulation, diabetes, previous coronary lesions, and heart failure (p < 0,005), increased baseline bleeding and ischemic risk (p = 0,05) and a higher heart rate upon admission (p < 0,05). After adjustment, only age > 80 years (OR 0,48, 95% CI 0,27 to 0,82, p = 0,009), known coronary lesions (OR 0,47, 95% CI 0,26-0,84, p = 0,011), and heart rate (OR 0,98, 95% CI 0,97-0,99, p = 0,003) were independently associated to conservative treatment. Smoking (OR 2.50, 95% CI 1.20 to 5.19, p = 0,013) and high-risk electrocardiogram (OR 2.96, 95% CI 1.72 to 4.97, p < 0,001) were associated to the early invasive strategy. The exclusion of early deaths (<24h) did not alter these results. CONCLUSIONS: In women with NSTE ACS, smoking and a high-risk electrocardiogram upon admission were independent factors associated to the early invasive strategy. Previous coronary lesions, age > 80 years and increased heart rate were independent factors associated to conservative treatment

[Gender bias in women with myocardial infarction: ten years after]. / Desigualdad de esfuerzo terapéutico en mujeres con infarto agudo de miocardio: 10 años después.

OBJECTIVE: Previous studies show that the women with acute myocardial infarction (AMI) receive less fibrinolitic treatment than the men. The objective of this study is to analyze if it exists any difference in fibrinolysis related to gender and to compare the results with those obtained 10 years ago. DESIGN: Retrospective descriptive study that compare patients with AMI of less than 24 hours of evolution of studies Analysis of Delay in Acute Infarct of Myocardium (ARIAM) in 2003-2004 and Project of Analysis Epidemiologist of Critical Patient (PAEEC) of 1992-1993. SETTING: ICUs from 86 hospitals in Spain that participated in the PAEEC study and 120 ICUs in the ARIAM. PATIENTS: We compared data of 9,981 patients including in study ARIAM in 2003-2004 with 1,668 of the PAEEC of 1992-1993. RESULTS: Women were less likely to receive thrombolytic therapy than men (odds ratio= 0.82, p < 0.01), after adjusting for age, origin, size of the hospital and antecedents. The probability of fibrynolisis is lower in elderly, patients referred from the general ward, in hospitals of more than 1,000 beds and patients with arterial hypertension, stroke, diabetes or peripheral vascular disease. The probability of fibrinólisis is higher when patient is transferred from another hospital (followed by those of Emergencies Room), in the hospitals by less than 300 beds (followed by those of 300-1,000) and when history of prior ischemic heart disease exists. Comparing the two periods, has increased the frequency of fibrynolisis in both genders, although the increment has been greater in the women. CONCLUSIONS: The women with AMI continue receiving less fibrynolisis, although exists an increase in the number of treatments superior to register in the men.

[Evaluation of the use of the pulmonary artery catheter in patients with acute myocardial infarct: The PAEEC study. Project of the Epidemiologic Analysis of Critical Illness]. / Evaluación del uso del catéter de arteria pulmonar en pacientes con infarto agudo de miocardio: el estudio PAEEC. Proyecto de Anánlisis Epidemiológico de Enfermos Críticos.

BACKGROUND: The aim of the study was to evaluate the impact of the use of the pulmonary artery catheter on hospital mortality in patients admitted to hospital for acute myocardial infarction. PATIENTS AND METHODS: This retrospective cohort study, included 1,721 patients whose main diagnosis was acute myocardial infarction and who were registered in the PAEEC study (a multicenter study including 86 intensive care units throughout Spain). RESULTS: A pulmonary artery catheter was implanted in 82 patients (4.8%). The mortality of the group with the catheter was 51.2%, being greater than that of the control group which did not receive the catheter (odds ratio [OR] = 8.56, 95% confidence interval [CI] range 5.25-13.93; p < 0.001). This excessive mortality persisted on adjusting for the APACHE-III, age, sex, diabetes, use of mechanical ventilation, vasoactive drugs and thrombolytic treatment (adjusted OR = 3.11; CI 1.59-5.57; p < 0.001). The TISS values of the patients in whom the catheter was implanted were greater than those expected for their age and APACHE-III level, being interpreted as an indicator of occult severity. On inclusion of the TISS values in the logistic regression model, the differences in mortality between the catheter and the control group decreased, but remained statistically significant (OR = 2.05; CI: 1.04-4.0; p = 0.039). CONCLUSIONS: The use of the pulmonary artery catheter was not found to contribute to reducing the mortality of patients with acute myocardial infarction. In fact, these results questions its use, particularly in less severe patients.
