4 The presence of the Metabolic Syndrome is associated with increased CHD, CVD and total mortality In a recently published analysis from the Kuopio Ischaemic Heart Disease Risk Factor Study of a male cohort of 1209 subject followed for almost 12 years, it was clearly shown that the metabolic syndrome is associated with a statistically increased risk for CHD, CVD, and total mortality, using either the ATP III or the WHO definition of the metabolic syndrome.Unadjusted Kaplan-Meier hazard curves for men with and without the Metabolic Syndrome based on factor analysis. Median follow-up was 11.6 ( ) years. Relative risks were determined by age-adjusted Cox proportional hazards regression analysis.Lakka HM et al, J Am Med Assoc 2002;288:

Declining HDL-C in the populationCurrent population trends in HDL-C show declining levels for both men and women across strata of other cardiovascular risk factors. In a 12-year population survey from the Pawtucket Heart Health Program, the mean population level of HDL-C declined 3 mg/dL. This is consistent with the growing problem with central obesity and insulin resistance and increasing prevalence of non–insulin dependent diabetes mellitus (type 2).Reference:Derby CA, Feldman HA, Bausserman LL, Parker DR, Gans KM, Carleton RA.

25 The Metabolic Syndrome Subjects with the metabolic syndrome also have a higher prevalence of microalbuminuria, left ventricular hypertrophy and arterial stiffness than those without the metabolic syndrome. Their cardiovascular risk is high and the chance of developing diabetes markedly increasedIn patients with a metabolic syndrome diagnostic procedures should include a more in-depth assessment of subclinical organ damage. Measuring ambulatory and home BP is also desirable
26 The Metabolic Syndrome In all individuals with metabolic syndrome individuals intense lifestyle measures should be adopted. When there is hypertension drug treatment should start with a drug unlikely to facilitate onset to diabetes. Therefore, a blocker of the renin-angiotensin system should be used followed, if needed, by the addition of a calcium antagonist or a low-dose thiazide diuretic. It appears desirable to bring BP to the normal rangeLack of evidence from specific clinical trials prevents firm recommendations on use of antihypertensive drugs in all metabolic syndrome subjects with a high normal BP. There is some evidence that blocking the renin-angiotensin system may also delay incident hypertension
29 BP Goals all be treated to <140/90 mm Hg Except : diabetes (<85 mm Hg diastolic)In patients near 80 years age, the systolic blood-pressure target should be 140 to 150 mm Hg, but physicians can go lower than 140 mm Hg if the patient is fit and healthy-mentally & physically
31 Life style changes Salt A reduction to 5 g per day can decrease systolic blood pressure about 1 to 2 mm Hg in normotensive individuals and 4 to 5 mm Hg in hypertensive patients, he said.Wt lossLosing about 5 kg can reduce systolic blood pressure by as much as 4 mm Hg, aerobic endurance trainingcan reduce systolic blood pressure 7 mm Hg
32 When to start drug RxConsider BP level and correlate with overall risk:cardiovascular risk factorsovert cardiovascular diseaseasymptomatic organ damagediabeteschronic kidney disease.
36 Combination RxFor patients at high risk for cardiovascular events or those with a markedly high baseline blood pressureIn those at low or moderate risk for cardiovascular events or with mildly elevated blood pressure, a single starting agent is preferred.For a high-risk individual, you can't play around with one drug after another, trying to control blood pressure

Treating HDL: Nonpharmacologic methodsEfforts to increase HDL-C include both nonpharmacologic and pharmacologic means. Although most favorable cardiovascular risk interventions may lead to increased HDL-C levels, exercise is commonly recommended. While exercise is very important as a general cardiovascular risk intervention, it has only limited efficacy in increasing HDL-C levels, being modestly effective only in the setting of elevated triglycerides and in response to frequent and intense exercise.

52 HDL-C Response to Exercise Kokkinos et al1 studied the relationship between exercise and HDL-C in 2,906 healthy, nonsmoking men. They found that there was a dose-response relationship between miles run per week and increasing HDL-C levels. Most of the increases in HDL-C were noted in men who ran 7 to 14 miles a week, a distance and level of effort equivalent to moderate jogging or brisk walking 30 minutes daily, 3 to 5 times per week.Savage et al2 found that women had greater improvement in HDL-C with cardiac rehabilitation than men, even though changes in fitness and body composition were similar. Women showed improvement regardless of baseline HDL-C, while only men with low HDL-C at baseline showed an increase in HDL-C.Kokkinos PF, Holland JC, Narayan P, Colleran JA, Dotson CO, Papademetriou V.

53 Lipids and Exercise Duration of exercise effect on lipids TG increase delays for several hours after exercise and this effect can persist for hours or several days when exercise is prolonged and intense.Usually HDL begins to rise after >10 weeks of exerciseSingle exercise sessions reduce postprandial hyperlipidemia but have no other effect on lipids.After exercise cessation lipids return on original valuesThe longer the exercise program lasted the longer the favorable lipid profile remains after exercise cessation.
54 Smoking Cessation Increases HDL-C Level In study by Moffatt, smokers had HDL-C levels 15–20% lower than nonsmokers (P < 0.05).1PROCAM showed less of an effect of smoking on HDL-C (7% lower than nonsmokers).2HDL-C levels returned to normal within 30–60 days after smoking cessation.1In eight women who smoked > 1 packs per day for 5 years, HDL-C levels increased from 51 to 64 mg/dL after quitting for 60 days.1Smoking Cessation Increases HDL-C LevelMoffat evaluated the effects of smoking cessation in 26 women who had smoked at least 20 cigarettes per day for the preceding 5 years. Twelve subjects stopped smoking for 60 days (ex-smokers); six stopped smoking for 30 days and then resumed smoking for an additional 30 days (re-smokers); and eight subjects continued to smoke for the entire 60 days (smokers). Ten women who had never smoked served as controls (nonsmokers). Before smoking cessation, all three smoker groups had high-density lipoprotein cholesterol (HDL-C) levels that were 15–20% (P < 0.05) lower than those of the nonsmokers. (Other studies, however, have shown less of an effect of smoking on HDL-C levels, e.g., the Münster Heart Study [PROCAM], in which mean HDL-C levels were reduced by 6.4% in male smokers and by 6.7% in female smokers versus nonsmokers.) In ex-smokers, HDL-C levels increased by 5.7 mg/dL by day 30 and by an additional 6.8 mg/dL by day 60, reaching 63.9 mg/dL. In contrast, HDL-C levels in re-smokers returned to precessation values (50.7 mg/dL) by day 60 (P < 0.05).References:Moffatt RJ.

55 Weight and HDL-CInverse correlation between body weight and HDL-C is consistently observed in both men and women.For every 3 kg of weight loss, HDL-C levels increase 1 mg/dL.Weight and HDL-C In 1988, the National Cholesterol Education Program’s Panel Report identified obesity (i.e., 30% overweight) as a factor for clinicians to consider when evaluating cholesterol concentrations and determining treatment. Even mild to moderate excess weight is associated with an increased risk of coronary heart disease. Dattilo and Kris-Etherton conducted a meta-analysis of 70 studies (published between 1966 and 1989) to examine the effects of weight loss by dieting on lipids and lipoproteins. They found a consistent linear association between weight loss and high-density lipoprotein cholesterol (HDL-C) concentrations in both men and women. For every 3 kg (7 lb) of weight loss, HDL-C levels increased 1 mg/dL when weight reduction was maintained.References:Expert Panel.

56 Caloric Restriction Acutely Lowers HDL-C Level Trials of very-low-calorie diets show that HDL-C levels decrease by 2–12 mg/dL during acute caloric restriction.After 12 wks, HDL-C returned to pretreatment range, and this trend was still apparent after 1 year.Therefore, benefits of weight-loss programs should not be assessed during acute caloric restriction.Caloric Restriction Acutely Lowers HDL-C LevelTrials of very-low-calorie diets show that high-density lipoprotein cholesterol (HDL-C) levels decrease by 2–12 mg/dL during acute caloric restriction. For example, Rössner and Björvell reported significant (P < 0.05) reductions in HDL-C concentrations after 6 weeks of weight loss in 118 grossly obese patients (mean weight in 46 men: 137 kg; mean weight in 72 women: 111 kg). After 12 weeks, however, HDL-C returned to the pretreatment range in both men and women, and this trend was still apparent after 1 year in 15 obese patients who continued to lose weight (weight at baseline: 120 kg; weight at Week 6: 105 kg; and weight at Week 52+: 100 kg). These data indicate that the HDL-C benefits of weight-loss programs should not be assessed during acute caloric restriction, since it may be expected that lipoprotein metabolism will differ in a catabolic early stage compared with a later stable situation at a lower body weight.Reference:Rössner S, Björvell H. Early and late effects of weight loss on lipoprotein metabolism in severe obesity. Atherosclerosis. 1987;64:125–130.Rössner S et al. Atherosclerosis 1987;64:125–130
57 Alcohol Increases HDL-C Level Alcohol increases HDL-C level in a dose-dependent manner.Half bottle of wine per day (39 g alcohol) for 6 weeks significantly increased mean HDL-C level by 7 mg/dL in 12 healthy subjects.1Wine intake did not significantly affect Total-C, Total-TG, or LDL-C.1One beer per day (13.5 g alcohol) for 6 weeks significantly increased mean HDL-C level by 2 mg/dL in 20 healthy subjects.2Beer intake did not significantly affect LDL-C, VLDL-C, TG, or apolipoproteins.Alcohol Increases HDL-C LevelModerate alcohol intake has been associated with a decreased risk of cardiovascular disease, which may be mediated by high-density lipoprotein cholesterol (HDL-C). Evidence indicates that alcohol intake increases HDL-C concentrations. For example, Thornton and colleagues showed that consumption of half a bottle of white wine (39 g alcohol) per day for 6 weeks significantly (P < 0.01) increased mean HDL-C levels––from 41 to 48 mg/dL––in 12 healthy, normolipidemic subjects (nine women and three men). None of the subjects was taking medication, and none smoked tobacco. The subjects’ wine intake did not significantly change total plasma cholesterol (Total-C), total triglyceride (Total-TG), or low-density lipoprotein cholesterol (LDL-C) concentrations. However, one must consider the calories added to the diet by alcohol use. The 39 g of alcohol consumed per day for 42 days in this study represent a total of 11,466 additional calories––the equivalent of 3 lbs of additonal weight (11,466 cal ÷ 3,600 cal/lb) over 6 weeks, or approximately 27 lbs per year! A more moderate alcohol intake was described by McConnell et al. In this study, 20 healthy nonsmokers (11 men and 9 women; aged 23–51 years) completed a 10-week program of controlled alcohol consumption, which consisted of 2 weeks of alcohol abstention; 6 weeks of alcohol use (one 12-ounce Samuel Adams Boston Lager––13.5 g of ethyl alcohol––each evening); and 2 additional weeks of abstention. Compared with the mean abstention level, the mean HDL-C level significantly (P = 0.03) increased 2 mg/dL (from 52 to 54 mg/dL) after consumption of a single, daily alcoholic beverage for 6 weeks. LDL-C, very-low-density-lipoprotein cholesterol (VLDL-C), TG, and apolipoprotein levels were not significantly changed.References:Stason WB, Neff RK, Miettinen OS, Hershel J.

60 HDL-C Response to Pharmacological Intervention Because all of the available drugs that increase HDL-C levels have significant effects on other lipoproteins, it has not been possible to prove, in clinical trials, the benefit of raising HDL-C in isolation.1 However, because of the known correlation of low HDL-C levels with increased CAD risk, the magnitude of the HDL-C elevation achievable with pharmacological treatments has become a point of interest in many trials of lipid-altering therapy. This slide shows the range of HDL-C elevations that have been observed with various lipid-modifying agents, used alone or in combination.1-41. Belalcazar LM, Ballantyne CM.
