title: Clinical lipid control success rate before and after percutaneous coronary intervention in iran; a single center study.
abstract: BACKGROUND
  High cholesterol levels have long been considered an independent risk factor for cardiovascular disease (CVD).
  
  
  OBJECTIVE
  Controlling risk factors such as dyslipidemia in patients with coronary artery disease is necessary. We aimed to evaluate the success rate of lipid control, during 9 months follow-up after percutaneous coronary intervention (PCI).
  
  
  METHODS
  A total of 195 patients (67.7% men, mean age = 57.8 ± 9.4 years) who underwent PCI in Tehran Heart Center were included. Serum lipid profiles were measured in all the patients before PCI and at 9-month follow-up. Dyslipidemia was defined as serum levels of LDL-C ≥ 100 or TG ≥ 150 or TC ≥ 200 or HDL-C ≤ 40 mg/dl in the men and ≤ 50 mg/dl or less in the women, or non-HDL-C ≥ 130 mg/dl with or without the consumption of lipid-lowering agents. During follow up, all patients were given atorvastatin 20-40 mg/day.
  
  
  RESULTS
  Overall, 26.2% had diabetes mellitus, 42.6% had hypertension, and 34.9% were smokers. Dyslipidemia was more common in the women. At 9-month follow-up, there was no significant changes in terms of the prevalence of high HDL-C or low TG in patients; however, a significant increase was seen in the prevalence low TC in patients (63.6% vs. 80.5%; p value < 0.001), LDL-C (47.2% vs. 65.6%; p value < 0.001), and non-HDL-C (40.0% vs. 63.1%; p value < 0.001).
  
  
  CONCLUSIONS
  Although by current treatments, the prevalence of patients with low TC, LDL-C and non-HDL-C has significantly increased; dyslipidemia persisted in a considerable proportion of patients. These results necessitate further investigations into the relationship between high serum lipids and long-term outcome of patients after PCI as well as further evaluations of the dyslipidemia treatment strategies.
