[Primary angioplasty in Argentina. Results from ARGEN-IAM-ST registry]
Abstract
Our objective was to evaluate clinical characteristics, results and morbi-mortality in primary angioplasty (PA), of patients treated with PA within 36 hours of a myocardial infarction (MI), included in a prospective, transversal, multicenter and national survey (ARGEN-IAM-ST). A total of 1142 patients treated with PA were registered, 61.2 ± 12 years old, 88% male, 20% diabetics and 58% with hypertension; 77.6% in Killip Kimball I and 6.2% in cardiogenic shock. The time from the onset of pain until admission was 153 (75-316) minutes, and door-balloon of 91 (60-150) minutes. The transferred patients (17%) showed longer delay to admission, 200 minutes (195-420; p = 0.0001) and door-to-balloon 113.5 minutes (55-207); p = 0.099. In 47.6% of the cases, the PA was made in the anterior descending artery, in 36.4% in the right coronary artery, in 14.8% in the circumflex artery and in 1.2% in the left coronary artery; in 95% with stent (29% pharmacological); 95% was successful, 1.3% presented post-infarct angina (APIAM), 1.3% re-infarct, 8.8% shock and 3.2% bleeding. Age > 64 years (OR 6.2 (95% CI: 3.2-12), p <0.001), diabetes (OR 2.5, 95% CI 1.6-3.9, p < 0.001), re-infarction or APIAM (OR 3.3, 95% CI 1.3-8.3, p = 0.011) and shock (OR 29.2 (15.6-54.8), p < 0.001) were independently associated with higher mortality. In-hospital mortality of acute myocardial infarction with ST-segment elevation treated with PA was 7.6%. Transference from other center was associated with delay in the admission and treatment. Cardiogenic shock and post-infarct ischemia were associated with high mortality. There were no procedural variables associated with mortality.
Se evaluaron las características clínicas, demoras, resultados y morbimortalidad de 1142 pacientes tratados con angioplastia primaria (AP) dentro de las 36 horas del infarto, incluidos en el registro ARGEN-IAM-ST, de carácter prospectivo, transversal, multicéntrico y de alcance nacional. Edades: 61.2 ± 12 años, 88% varones, 20% diabéticos y 58% hipertensos; 77.6% en Killip y Kimball I y 6.2% en shock cardiogénico. El tiempo desde el inicio del dolor hasta el ingreso fue de 153 (75-316) minutos, y puerta-balón de 91 (60-150) minutos. Los casos derivados (17%) tuvieron mayor demora de ingreso, 200 minutos (195-420; p = 0.0001) y mayor tiempo puerta-balón, 113 minutos (55-207); p = 0.099. En 47.6% de los casos la AP se hizo en arteria descendente anterior, en 36.4% a coronaria derecha, en 14.8% a circunfleja y en 1.2% al tronco de coronaria izquierda; en 95% con stent (29% farmacológico). El 95% fue exitoso. El 1.3% presentó angina post-infarto (APIAM), 1.3% re-infarto, 8.8% shock y 3.2% sangrado. Se asociaron a mayor mortalidad edad > 64 años (OR 6.2 (IC 95%: 3.2-12), p < 0.001), diabetes (OR 2.5, IC 95% 1.6-3.9, p < 0.001), re-infarto o APIAM (OR 3.3, IC 95% 1.3-8.3, p = 0.011) y shock (OR 29.2 (15.6-54.8), p < 0.001). La mortalidad hospitalaria del infarto agudo de miocardio con elevación del segmento ST tratado con AP fue de 7.6%. La derivación se asoció a demora de tratamiento. El shock cardiogénico y la isquemia post-infarto se asociaron a alta mortalidad. No hubo variables del procedimiento asociadas a mortalidad.
