ABSTRACT
Objectives: To investigate the status of secondary prevention, treatment and risk factors of retired elderly patients (≥80 years old) with coronary heart disease in Guangzhou. Methods: A total of 752 questionnaires were collected from the elderly patients with coronary heart disease who underwent routine cardiovascular checkup in our hospital from March to May in 2016. The questionnaire included basic situation, complications, weight, blood pressure, low density lipoprotein, glucose level and secondary prevention medications based on evidence-based medicine. Results: Antiplatelet drugs, beta blockers, statins, ACEI/ARB use rate was 55.72%, 30.98%, 25.13%, 42.69% for the secondary prevention; 21.94% patients did not take secondary prevention drugs, the combined use rate of the four drugs was 4.92%. In elderly patients with coronary heart disease, the control rate of blood pressure (<150/90 mmHg), fasting blood glucose (<7mmol/L), 2-hour postprandial blood glucose (<10 mmol/L), body mass index (<24 kg/m2) were 81.17% (470/579 cases), 77.61% (253/326 cases), 55.21% (180/326 cases) and 54.73% (266/486 cases), respectively. With LDL-C<1.8 mmol/L as the standard, percent with normal LDL-C value was 14.06% (63/448 cases). Conclusions: In this survey population, use rate of the four types of drugs for secondary prevention and the control rate of known risk factors for coronary artery disease are very low. Efforts are needed to improve rational use of the secondary prevention drugs, minimize the gaps between promote the guidelines and clinical practice, and reduce the recurrence rate of coronary heart disease in elderly patients with coronary artery disease.
