Abstract
Background and objective

Little information exists about the prognostic impact of body mass index (BMI) in the elderly with acute coronary syndromes (ACS). We aimed to prospectively assess the association between BMI and midterm mortality in consecutive elderly patients with ACS.

Patients and method

We included consecutive ACS patients aged 75 years or older admitted to the Coronary Care Unit. Patients were stratified into five BMI subgroups (<20, 20–24.9, 25–29.9, 30–35, >35kg/m2). Primary endpoint was overall midterm mortality. Analyses were performed by Cox regression method.

Results

During the study period 600 patients were admitted, of whom 579 had known BMI values. Low weight patients (BMI<20kg/m2) were older, with higher prevalence of vasculopathy and lower creatinine clearance. Median follow up was 315 days. Patients with BMI<20kg/m2 had higher mortality as compared to the rest of groups. Adjusted analysis showed an attenuation of these differences, while maintaining significance for the groups of BMI 20–24.9 and 30–35kg/m2.

Conclusions

The association between BMI and mortality was mainly due to worse prognosis in low weight patients. Prospective assessment of comorbidities and other variables linked to ageing should contribute to better understand the association between BMI and mortality.

Resumen
Fundamento y objetivo

La información sobre el impacto pronóstico del índice de masa corporal (IMC) en el anciano con síndrome coronario agudo (SCA) es muy escasa. El objetivo fue analizar prospectivamente la asociación entre IMC y mortalidad a medio plazo en una serie de ancianos con SCA.

Pacientes y método

Se incluyeron pacientes consecutivos con SCA de 75 años o más ingresados en la Unidad Coronaria, estratificándose en 5 categorías (IMC <20, 20–24,9, 25–29,9, 30–35, >35kg/m2). El objetivo primario fue la mortalidad durante el seguimiento, analizándose mediante regresión de Cox.

Resultados

Durante el período de estudio ingresaron 600 pacientes ancianos, de los cuales 579 tenían valores conocidos de IMC. Los pacientes con IMC<20kg/m2 presentaban mayor edad, mayor prevalencia de vasculopatía y peor aclaramiento de creatinina. La mediana de seguimiento fue de 315 días. Los pacientes con IMC<20kg/m2 presentaron una mortalidad superior al resto. El ajuste estadístico mostró atenuación de dichas diferencias, conservando significación para las categorías de IMC 20–24,9 y 30–35kg/m2.

Conclusiones

La asociación entre IMC y mortalidad se basó fundamentalmente en un peor pronóstico en pacientes de bajo peso. Un registro prospectivo de comorbilidades y otras variables vinculadas al envejecimiento podría contribuir al conocimiento de esta asociación.
