RESUMEN

Objetivo:

Evaluar el impacto de los factores socioculturales (SC) en Las características del cuidado de la insuficiencia cardiaca (IC) y la evolución post alta en pacientes admitidos con diagnostico de IC descompensada a hospitales del registro ICARO en el periodo 2006-2008.

Método:

Registro prospectivo de 14 hospitales. Se incorporaron en forma consecutiva pacientes admitidos con el diagnostico de IC descompensada entre enero 2006 y mayo 2008. La mortalidad al fin del seguimiento se determino por la base de datos del Servicio Nacional del Registro Civil e Identificación. Se definió como terapia optima la combinación de en betabloqueador con cualquiera de los siguientes inhibidores de la enzima convertidora de angiotensina (IECA), antagonistas del receptor de angiotensina Il (ARAlI), hidralazina/isosorbide o espironolactona. Las características de los pacientes se compararon mediante t de Student o chi cuadrado según correspondía. La sobrevida se evaluó mediante Kaplan-Meier.

Resultados:

Los pacientes de bajo nivel SC son do mayor edad (71 +/- 11 v/s 66 +/-15 años respectivamente, p<0.01). predomina el género femenino (52.2 por ciento v/s 26.1 por ciento, p<0,01), y su previsión fue mayoritariamente FONASA (90 por ciento). La etiología isquémica fue más frecuente en el estrato SC alto (34,5 vs. 16,6 por ciento) y la hipertensiva en el nivel SC bajo (30,3 v/s 16,6 por ciento). La utilización de ARA II fue más frecuente en el nivel SC alto con una tendencia a menor utilización de IECA, el uso de betabloqueadores espironolactona hidralazina e isosorbide amiodarona y anticoagulante fue menor en el estrato SC bajo.
ABSTRACT

Aim:

to evaluate de impact of social and cultural (S-C) factors in the care and course of patients with congestive heart failure (CHF) enrolled in the ICARO study (national registry for patients with head failure).

Methods:

Patients were enrolled from 2006 through 2008. They were discharged from 14 hospitals participating in the prospectively designed ICARO study. Late mortality was obtained from the national Identification registry. Optimal medical therapy was defined as the use of a betablocker in addition to any of the following ACE inhibitors, ARA II. combination of hydralazine and nitrates, or spironolactone. Statistical analysis included Students t tesl. chi square and Kaplan Meir and Log-rank testing, as appropriate.

Results:

Patients with a low S-C level were older (71 +/- 11 vs 66 +/- IS years. p<0.01). more frequently females (52.2 percent vs 26.1 percent, p<0.01) and most of them belonged in the FONASA health insurance system (90 percent). Ischemic heart disease was more prevalent in the high S-C level (34.5 vs 16.6 percent) and hypertension in the low S-C level (30.3 vs 16.6 percent). ARA II rather than ACE inhibitors were more commonly used in the high S-C level A CE inhibitors, betablockers, spironolactone, hydralazine-nitrates, amiodarone and anticoagulatioo were less frequently used in the low S-C level. After discharge a more intensive treatment of heart failure was observed; however, this was less seen in the low S-C level. Patients with decreased left ventricular ejection fraction were similarly treated in both groups. An optimal therapy for CHF was used in 43.7 percent, 43.3 percent and 51.1 percent in S-C levels low, intermediate and high, respectively (NS). Independent predictors for late mortality were age>70 years (HR 2.71 (CI 1.55-3.03), low S-C level (HR 1.57, CII. 17- 2.09), EF<50 percent (HR 1.49, CI 1.04-2.14) and absence of optimal medical therapy at discharge (HR 0.52, CI 0.41-0.66).
