May lead to stroke, severe headaches, internal bleeding, unconsciousness, death. Usually at areas where there is bifurcation (branching of artery) Nih labeled ldl-cholesterol level below 100 mg/dl. Increase glucose, glycation, inflammation oxidation of ldl, inflammation causes vasoconstriction, hr causes platelet stickiness -> risk of thrombus serum lipid level monoxide (displace o2 from hemoglobin) Antiotensin ii: hormone responsible for high bp also appears to incite inflammation rxn. Infections reduces inflammation by carrying antioxidants in blood to break down. As aging, reduce cholesterol/saturated fats in your diet cholesterol should be 300mg/day. High alcohol consumption -> ldl coffee -> ldl. Males have higher risk of cv disease. Bp smoking + birth control heart attack risk 18-fold. Add toxins to blood -> plaque formation. Exercise raises hdl"s in blood lowers ldl. As well as workload for the heart.
