Abstract
Background
Reduction of LDL-cholesterol (LDL-c) levels is the cornerstone in risk reduction, but many high-risk patients are not achieving the recommended lipid goals, even in high-income countries.
Objective
To evaluate whether patients seen in the city of Curitiba public health system are reaching LDL-c goals after an acute myocardial infarction (AMI).
Methods
This retrospective cohort explored the data of patients admitted with AMI between 2008 and 2015 in public hospitals from the city of Curitiba. In order to evaluate the attainment of the LDL-c target, we have used the last value registered in the database for each patient up to 2016. For those who had at least one LDL-c registered in the year before AMI, percentage of reduction was calculated. The level of significance adopted for statistical analysis was p<0.05.
Results
Of 7,066 patients admitted for AMI, 1,451 were followed up in an out-patient setting and had at least one evaluation of LDL-c. Mean age was 60.8±11.4 years and 35.8%, 35.2%, 21.5%, and 7.4% of patients had LDL-c levels ≥100, 70–99, 50–69 and <50 mg/dL, respectively. Of these, 377 patients also had at least one LDL-c evaluation before the AMI. Mean LDL-c concentrations were 128.0 and 92.2 mg/dL before and after AMI, with a mean reduction of 24.3% (35.7 mg/dL). LDL-c levels were reduced by more than 50% in only 18.3% of the cases.
Conclusion
In the city of Curitiba public health system patients, after myocardial infarction, are not achieving adequate LDL-c levels after AMI.
