<prompt> All of the following are risk factors for atherosclerosis except :Increased waist - hip ratioHyperhomocysteinemiaDecreased fibrinogen levelsDecreased HDL levels  <response>: Answer is C Decreased fibrinogen levels Increased levels of .fibrinogen and not decreased fibrinogen levels are associated with increased risk of atherosclerosis. Fibrinogen Levels Fibrinogen levels correlate with coronary risk and provide information regarding coronary risk independent of lipoprotein profile. Elevated fibrinogen levels might promote a thrombotic diathesis. Waist Hip Ratio : This refers to a characteristic male distribution of adipose tissue i.e. excess of fat in the abdomen compared with that in hips. An elevated waisthip ratio has been associated with symptomatic cardiovascular disease and cerebrovascular disease in both men and women. - Pubmed NCBI - website Hyperhomocvsteinemia and low HDL levels are known risk factors for Atherosclerosis as depicted in the following table. Major risk Factors for Atherosclerosis Cigarette smoking Hypeension BP 14090mmhg or on Antihypeensive medication Low HDL cholesterol Diabetes mellitus Family history of CHD Age Men 45 years; Women 55 years Life style risk factors Obeity BMI 30 kgm2 Physical inactivity Atherogenic diet Emerging risk factors Lipoprotein a Homocystine Prothrombotic factors Fibrinogen Pro inflammatory factors Impaired fasting glucose Subcl inical atherogenesis
