Objective: -Lipid control is essential after an acute myocardial infarction (AMI). -The information regarding the grade of lipid control in hypertensive patients after an AMI is scarce. -Our objective was to assess the grade of lipid control according to their antihypertensive treatment. Design and method: -The sample includes 130 patients admitted during the year 2017 in the Cardiology department with a diagnosis of AMI (ICD 9 410) and with, at least, one ambulatory lipid determination during the follow-up. The threshold to considerer an appropriate lipid control was 55 mg/dL but we also analyzed according to the previously threshold of 70 mg/dL. -Differences regarding the percentage of lipid control were evaluated using the Chi-square test. This analysis was adjusted by the intensity of lipid treatment and by the type and number of antihypertensive drugs used. -Mean differences in lipid levels were assessed using ANOVA. This analysis was adjusted by age, sex and the intensity of lipid treatment. -The relationship between lipid levels and the time elapsed since the infarction was assessed by means of Pearson's correlation coefficient. -Every statistical analysis was performed using Stata IC 14. Results: -Globally, the level of control was 31% considering 55 mg/dL and an additional 29% if 70 mg/dL was the desired LDLc threshold. Although the percentage of controlled patients increased according to the number of antihypertensive medications, these differences were not statistically significant. -The same occurs for the LDLc levels, which were similar among groups: 0–1; 2–3 or more than 3 antihypertensive drugs (figure 1). The only significant differences were found in those having diuretics who have higher LDL levels (77,2 vs 64,4 mg/dL, respectively, p-value=0.04) in the unadjusted but not after adjustment and without any differences in the percentage of control. -A positive correlation was found between the LDLc and the elapsed time since the AMI. Conclusions: -The percentage of lipid control after an AMI is low and it seems to get worse along time. -We did not find an association between the complexity of antihypertensive treatment and the LDL levels. Diuretics could impact negatively the grade of lipid control.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
