Economic evaluation of complete revascularization versus stress echocardiography-guided revascularization in the STEACS with multivessel disease.

INTRODUCTION AND OBJECTIVES: Economic studies may help decision making in the management of multivessel disease in the setting of myocardial infarction. We sought to perform an economic evaluation of CROSS-AMI (Complete Revascularization or Stress Echocardiography in Patients With Multivessel Disease and ST-Segment Elevation Acute Myocardial Infarction) randomized clinical trial. METHODS: We performed a cost minimization analysis for the strategies (complete angiographic revascularization [ComR] and selective stress echocardiography-guided revascularization [SelR]) compared in the CROSS-AMI clinical trial (N=306), attributable the initial hospitalization and readmissions during the first year of follow-up, using current rates for health services provided by our health system. RESULTS: The index hospitalization costs were higher in the ComR group than in SelR arm (19 657.9±6236.8 € vs 14 038.7±4958.5 €; P <.001). There were no differences in the costs of the first year of follow-up rehospitalizations between both groups for (ComR 2423.5±4568.0 vs SelR 2653.9±5709.1; P=.697). Total cost was 22 081.3±7505.6 for the ComR arm and 16 692.6±7669.9 for the SelR group (P <.001). CONCLUSIONS: In the CROSS-AMI trial, the initial extra economic costs of the ComR versus SelR were not offset by significant savings during follow-up. SelR seems to be more efficient than ComR in patients with ST-segment elevation acute coronary syndrome and multivessel disease treated by emergent angioplasty.

Comparación del valor predictivo pronóstico de los scores TIMI, PAMI, CADILLAC y GRACE en el SCACEST sometido a ICP primario o de rescate / Comparison of the prognostic predictive value of the TIMI, PAMI, CADILLAC, and GRACE risk scores in STEACS undergoing primary or rescue PCI

Introducción y objetivos. Nos planteamos comparar el valor predictivo pronóstico de los scores de riesgo Thrombolysis In Myocardial Infarction (TIMI), Controlled Abciximab and Device Investigation to Lower Late Angioplasty Complications (CADILLAC), Primary Angioplasty in Myocardial Infarction (PAMI) y Global Registry for Acute Coronary Events (GRACE) para el síndrome coronario agudo con elevación del ST sometido a intervencionismo coronario percutáneo urgente. Métodos. Análisis retrospectivo de una cohorte compuesta por todos los pacientes con un síndrome coronario agudo con elevación del ST tratados en nuestro centro mediante intervencionismo coronario percutáneo urgente entre 2006-2010 (n=1.503). Para cada paciente, calculamos la puntuación de los scores TIMI, PAMI, CADILLAC y GRACE según diferentes variables clínicas. Valoramos el valor predictivo de los cuatro scores para muerte, reinfarto y revascularización de vaso tratado a 30 días y 1 año mediante el estadístico C, empleando para su cálculo regresión logística y curvas ROC. Resultados. Los scores TIMI, PAMI, CADILLAC y GRACE mostraron un excelente valor predictivo para la mortalidad a 30 días y a 1 año (estadístico C; intervalo, 0,8-0,9), con superioridad de los modelos TIMI, CADILLAC y GRACE. El funcionamiento de estos scores fue pobre para la predicción de reinfarto y revascularización de vaso tratado (estadístico C, 0,5-0,6). Conclusiones. Los modelos TIMI, PAMI, CADILLAC y GRACE representan una excelente herramienta para la estratificación del riesgo de mortalidad en los pacientes sometidos a intervencionismo coronario percutáneo primario. Los scores TIMI, CADILLAC y GRACE poseen el mayor poder predictivo. Su utilidad resulta cuestionable para la predicción de reinfarto y revascularización de vaso tratado (AU)

Introduction and objectives. We sought to compare the predictive value of the Thrombolysis In Myocardial Infarction (TIMI), Controlled Abciximab and Device Investigation to Lower Late Angioplasty Complications (CADILLAC), Primary Angioplasty in Myocardial Infarction (PAMI), and Global Registry for Acute Coronary Events (GRACE) scores for the outcome of ST-segment elevation acute coronary syndrome undergoing urgent percutaneous coronary intervention. Methods. We performed a retrospective analysis of a cohort composed of all consecutive patients with ST-segment elevation acute coronary syndrome treated by urgent percutaneous coronary intervention between 2006 and 2010 (n=1503). TIMI, PAMI, CADILLAC, and GRACE risk scores were calculated for each patient according to different clinical variables. We assessed the predictive accuracy of these scores for death, reinfarction, and target-vessel revascularization at 30 days and 1 year, using the C statistic, which was obtained by means of logistic regression and ROC curves. Results. The TIMI, PAMI, CADILLAC and GRACE showed an excellent predictive value for 30-day and 1-year mortality (C statistic range, 0.8-0.9), with superiority of the TIMI, CADILLAC, and GRACE risk models. The performance of these 4 scores was poor for both reinfarction and target-vessel revascularization (C statistic, 0.5-0.6). Conclusions. The TIMI, PAMI, CADILLAC, and GRACE scores provide excellent information to stratify the risk of mortality in patients treated by percutaneous coronary intervention. The TIMI, CADILLAC, and GRACE models have higher predictive accuracy. The usefulness of these models for reinfarction and target-vessel revascularization prediction is questionable (AU)
