The control of Low-Density Lipoprotein Cholesterol in the elderly at the clinic of health protective committee for high ranking cadre of Ca Mau province

Abstract

Background: Intensive control of low-density lipoprotein (LDL-C) helps the elderly to prevent primary and secondary cardiovascular events. Objective: Study on the current status of LDL-C control in the elderly at the clinic of Health Protective Committee for High Ranking Cadre of Ca Mau province from November 2020 to January 2021 according to the 2019 European Society of Cardiology and European Atherosclerosis Society guidelines (ESC/EAS 2019). Method: Study included 674 elderly people (≥60 years of age) at the clinic of Health Protective Committee for High Ranking Cadre of Ca Mau province. This was a cross-sectional study, which collected clinical information, medical history and measured the LDL-C serum concentration to classify the cardiovascular risk and the LDL-C control status. Results: This study involved 554 males (82.20%) and 120 females (17.80%). The mean age was 69.28. The age group 60-69 accounted for the highest rate (59.35%). The proportion of the elderly with very high, high, and moderate cardiovascular risk factors according to the ESC/EAS 2019 classification was 34.27%, 44.36% and 21.37%, respectively. There was no one in the low-risk group. The achieving LDL-C target rate was 22.7%. The proportion of achieving LDL-C target in males and females was 21.48% and 28.33% (p=0.104), respectively. In the 60-69 years of age group, the proportion reached the LDL-C target was 23.25%, while the over 69 years old group reached 21.9% (p=0.681). Specific, according to the cardiovascular risk classification, the rate of elderly in the very high-risk group and the high-risk group who achieved LDL-C target was 12.99% and 18.06%, respectively, statistically significantly lower than the moderate-risk group reached 47.92 % (p<0.001). Conclusion: The rate of reaching the LDL-C target following ESC/EAS 2019 guidelines of the elderly at the clinic of Health Protective Committee for High Ranking Cadre of Ca Mau province was relatively low. The rate of the elderly in moderate cardiovascular risk group had a higher percentage of LDL-C target achievement than those in the very high-risk and high-risk groups. There was no statistically significant between reaching LDL-C target with the age and sex.
