Mortality and compliance with secondary prevention goals of ischaemic heart disease in patients ≥70 years: observational study.

Introduction and Objectives: The 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.
Methods: An 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.
Results: During 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).
Conclusion: Control 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.
