  14. Impact of Recent Clinical Trials: Revised CAD Risk Categories

  15. Estimate total CVD risk of fatal CVD event in 10 years using SCORE chart Total CVD risk <5% TC 5 mmol/L (190 mg/dL) Total CVD risk 5% TC 5 mmol/L (190 mg/dL) Measure fasting lipids, give lifestyle advice, with repeat lipids after 3 months Lifestyle advice Aim: TC<5 mmol/L (190 mg/dL) LDL-C <3.0 mmol/L (115 mg/dL) Follow-up at 5-year intervals TC 5 mmol/L (190 mg/dL) or LDL-C 3 mmol/L (115 mg/dL) Maintain lifestyle advice and start drug therapy TC <5 mmol/L (190 mg/dL) and LDL-C <3.0 mmol/L (115 mg/dL) Maintain lifestyle advice with annual follow-up. If total risk remains 5%, consider drugs to lower TC to <4.5 mmol/L (175 mg/dL) and LDL-C to <2.5 mmol/L (100 mg/dL) 2003 European Guidelines:Guide to lipid management in asymptomatic subjects De Backer G et al. Eur Heart J 2003;24:1601–1610.

  16. 3rd European Guidelines Goals - Risk factors: • Prophylactic drug therapy should be considered in particular groups. These parameters have been summarized as a mnemonic for the practitioner as the "European heart health telephone number": 14090530 • 140 mm Hg SBP • 90 mm Hg DBP • 5 mmol/L (150 mg/dL) total cholesterol • 3 mmol/L (115 mg/dL) LDL cholesterol • 0 NO SMOKING

  17. Risk estimation is based on age, sex, smoking habits, systolic blood pressure (SBP), and either total cholesterol or cholesterol/HDL ratio.[7] Using the SCORE model, risk charts can be provided for all European countries. Total risk can be calculated from SCORE charts The low-risk chart is for countries such as Belgium. France, Greece, Italy, Luxembourg, Portugal, Spain, and Switzerland. Relative risk is calculated by comparing an individual's risk category with that of a nonsmoking person of the same age and gender with blood pressure </= 140/90 mm Hg and total cholesterol < 5 mmol/L (< 190 mg/dL).

  18. Risk estimation is based on age, sex, smoking habits, systolic blood pressure (SBP), and either total cholesterol or cholesterol/HDL ratio.[7] Using the SCORE model, risk charts can be provided for all European countries. Total risk can be calculated from SCORE charts. The high-risk chart is for use in all other European countries. Relative risk is calculated by comparing an individual's risk category with that of a nonsmoking person of the same age and gender with blood pressure </= 140/90 mm Hg and total cholesterol < 5 mmol/L (< 190 mg/dL).
