Risk Factor Concepts in Primary Prevention Nonmodifiable risk factors include age, sexc, race, and family history of CVD, which can identify high-risk populations Behavioral risk factors include sedentary lifestyle, unhealthful diet, heavy alcohol or cigarette consumption. Physiological risk factors include hypertension, obesity, lipid problems, and diabetes, which may be a consequence of behavioral risk factors.
Population vs. High-Risk Approach Risk factors, such as cholesterol or blood pressure, have a wide bell-shaped distribution, often with a tail of high values. The high-risk approach involves identification and intensive treatment of those at the high end of the tail, often at greatest risk of CVD, reducing levels to normal. Κσδσλνεηδήο Καηαλνκή But most cases of CVD do not occur among the highest levels of a given risk factor, and in fact, occur among those in the average risk group. Significant reduction in the population burden of CVD can occur only from a population approach shifting the entire population distribution to lower levels.

Lipid levels in patients hospitalized with coronary artery disease An analysis of 136,905 hospitalizations in Get With The Guidelines Conclusions: In a large cohort of patients hospitalized with CAD, almost half have admission LDL levels <100 mg/dl. More than half the patients have admission HDL levels <40 mg/dl, whereas <10% have HDL 60 mg/dl. These findings may provide further support for recent guideline revisions with even lower LDL goals and for developing effective treatments to raisehdl. (Am Heart J 2009;157:111-7.e2.)

Recommendations for treatment targets for LDL-C Recommendations Class Level In patients at VERY HIGH CV risk {established CVD, type 2 diabetes *, type 1 diabetes with target organ damage, moderate to severe CKD or a SCORE level > 10%) the LDL-C goal is < 1.8 mmol/l {less than ~ 70 mg/dl) and/or > 50% LDL-C reduction when target level cannot be reached. IC In patients at HIGH CV risk {type 2 diabetes **, markedly elevated single risk factors, a SCORE level > 5 to < 10%) an LDL-C goal < 2.5 mmol/l {less than ~ 100 mg/dl) should be considered. lla In subjects at MODERATE risk {SCORE level > 1 to< 5%) an LDL-C goal < 3.0 mmol/l {less than -115 mg/dl) should be considered. lla European Heart Journal 2011;32 (14):17G9-181S Atherosclerosis 2011Jul;217{1):346 www.escardio.ong/guidelines SOCIETY OF CAnotouxt*
