Methods This was a retrospective study including consecutive subjects 〉 65 years old （n = 465） with a follow-up 〉 3 years. Low-density lipoprotein cholesterol （LDL-C）, blood pressure （BP） and glycated hemoglobin （HbAlc） goal achievement were recorded according to European Society of Cardiology/European Atherosclerosis Society （ESC/EAS）, European Society of Hypertension （ESH）/ESC and European Association for the Study of Diabetes （EASD） guidelines. Results The LDL-C targets were attained by 27~,4, 48% and 62% of very high, high and moderate risk patients, respectively. Those receiving statin ＋ ezetimibe achieved higher rates of LDL-C goal achievement compared with those receiving statin monotherapy （48% vs. 33%, P 〈 0.05）. Of the diabetic sub- jects, 71% had BP 〈 140/85 mmHg, while 78% of those without diabetes had BP 〈 140/90 mmHg. A higher proportion of the non-diabetic individuals （86%） had BP 〈 150/90 mmHg. Also, a higher proportion of those with diabetes had HbAlc 〈 8% rather than 〈 7% （88% and 47%, respectively）. Of note, almost one out of three non-diabetic individuals and one out of ten diabetic individuals had achieved all three treatment targets. Conclusions Even in a specialist setting of a University Hospital, a high proportion of the elderly remain at suboptimal LDL-C, BP and HbAlc levels. The use of drug combinations could improve multifactorial treatment target attainment, while less strict tar- gets could be more easily achieved in this population.展开更多
