Present situation on therapy and secondary prevention of coronary heart disease in the elderly / 中华老年医学杂志

ABSTRACT

Objective To investigate the present situation on therapy and secondary prevention of coronary heart disease (CHD) in the elderly,and to improve treatment and secondary prevention.Methods Cross sectional,non-intervention and multicenter survey was used in this study.All 7962 effective interviewed cases were with aged ≥60 years from 116 hospitals of 21 provinces and cities during April and July of 2011.Among them,male was 63.4％,aged (73.0±7.9) years,24.1％cases were aged ≥80 years.The current treatment and risk factors of elderly CHD were investigated by questionnaire including basic information,health check,types and severe degree of CHD,its therapy and prevention,and control of the risk factors.Results (1) All cases were received drugs and percutaneous coronaryintervention (PCI) or surgery,27.5％ cases of PCI,2.6％ of coronary artery bypass grafting(CABG),70.4％ cases of expectant treatment.(2) The ratio of cases with angina pectoris and myocardial infarction was 76.5 ％,the attack of angina pectoris ≥3 times/weeks in recent month was 48.3％,Canadian Cardiovascular Society(CCS) Ⅱ scores and over was 79.3％.(3) The utility ratio of prevention drugs recommended by the guidelines were 70.3％ antiplatelet drug,54.9％ lipid regulating agents,47.5％ BB,29.0％/22.2％ ACEI/ARB.(4)The situation of risk factor control was as followedamong all the cases,38.9％ of them with active smoking≥1 counts/day,28.4％ of them with passive smoking,57.6％ of them with BMI ≥24,46.4％ of male with waistline ≥90 cm,41.1％ of female with waistline≥85 cm.In our cases,67.6％ of them with hypertension and 56.6％ achieved the level of blood pressure＜140/90 mm Hg; 23.4％ with diabetes mellitus and 49.5％ achieved the level of HbA1c ＜7.0％; 33.2％ with Lipids disorder and 26.6％ achieved the level of TC＜4.1 mmol/L,27.5％ of LDL-C＜2.6 mmol/L.(5) The analysis showed that there were more attacks of angina pectoris in the groups of male than female(P=0.0050),those HbA1c ≥7.0％ than those ＜7.0％ (P=0.019),and those LDL-C≥2.6 mmol/L than those ＜2.6 mmol/L (P =0.044),and that there were less attacks in those with CABG than without it (P＜0.001) and in those with PCI than without it (P＜0.001).Conclusions Inadequate control of symptom,insufficient utility ratio of prevention drugs and control of risk factors appear in elderly CHD.Coronary revascularization,drug use of guidelines recommend and control of high risks are the key points of high curative effect of elderly CHD.
