Mortality and compliance with secondary prevention goals of ischaemic heart disease in patients ≥70 years: observational study. / Mortalidad y cumplimiento de los objetivos de prevención secundaria de la cardiopatía isquémica en pacientes ≥70 años: estudio observacional.

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.

Secondary prevention programme of ischaemic heart disease in the elderly: A randomised clinical trial.

Background Elderly patients have been underrepresented in secondary cardiovascular prevention programmes. This study aimed to ascertain the effects of a secondary coronary disease prevention programme in these patients. Design Open randomised intervention study with parallel groups. Methods One hundred and twenty-seven patients aged ≥70 years with a recent acute coronary syndrome were randomised to a protocolised clinical intervention plus usual care (intervention group, n = 64) or to usual care alone (control group, n = 63). Patients were assessed at baseline and after 12 months. The main outcome was the percentage of patients with optimal risk factor control after 12 months of follow-up. Secondary outcomes included changes in Mediterranean diet adherence, quality of life and functionality. Mortality was evaluated three years after the end of the intervention. Results One hundred and six patients (83.4%) completed 12 months of follow-up (54 in the intervention group and 52 in the control group). At the end of intervention, 34.2% more patients in the intervention group had achieved optimal risk factor control with a number needed to treat of 3 (relative risk 2.18, 95% confidence interval 1.36 to 3.50). The intervention group improved adherence to the Mediterranean diet ( p = 0.013) and functionality assessed by the Short Physical Performance Battery ( p = 0.047). No differences between groups were found in quality of life (Short-Form 36 Health Survey) or mortality after three years (hazard ratio 1.19, 95% confidence interval 0.41 to 3.45). Conclusions A secondary coronary disease prevention programme in elderly patients with a recent acute coronary syndrome improved risk factor control, Mediterranean diet adherence and functionality.
