Mortalidad y cumplimiento de los objetivos de prevención secundaria de la cardiopatía isquémica en pacientes ≥ 70 años: estudio observacional

Abstract

Introduction and objectivesThe benefit of secondary prevention of ischaemic heart disease in terms of mortality in people of advanced age has not been well demonstrated. In this study we analyse the relationship of all-cause mortality with meeting the objectives of secondary prevention of ischaemic heart disease in elderly patients. MethodsAn observational study of a sample of 106 patients ≥70 with a history of acute coronary syndrome in the previous year. We analysed the association between meeting the objectives of secondary prevention of ischaemic heart disease and global mortality at 3 years. ResultsDuring the 3 years of follow-up, 15.1% of the patients died. Control of LDL cholesterol was associated with lower mortality (HR=.08 [.01-.61], p=.014). By contrast, strict control of blood pressure was associated with a tendency towards higher mortality (HR=3.2 [.9-11.47], p=.073). ConclusionControl of LDL cholesterol in the elderly population with ischaemic heart disease is the single therapeutic objective that can have a favourable effect on medium-term survival.
