1 Preventing the Clinical Manifestations of CV Disease in Asia: Opportunities for Lipid Management
Slides prepared and presented by Prof John JP Kastelein Academic Medical Centre Amsterdam, The Netherlands

2 The Burden of CVD in Asia: CHD Deaths by Country, 2002
Cardiovascular disease (CVD), including stroke and coronary heart disease (CHD), is a leading cause of mortality in the East Asia and Pacific region, according to 2002 World Health Organization (WHO) statistics. For example, in China, stroke was responsible for more than 1.5 million deaths and CHD led to more than 700,000 deaths in 2002 alone.

4 Age-Standardized Stroke and CHD Death Rates by Country, 2002
Age-standardized mortality rates for stroke are elevated in East Asian Pacific countries and are generally higher than in Western countries. East Asian countries have lower CHD mortality rates than do Western countries, but South Asian and some Southeast Asian countries have age-standardized mortality rates for CHD that are comparable to or higher than those of Western countries.

5 Projected Stroke and CHD Increase to 2030 in China
A computer model (CHD Policy-China, a Markov model of CVD in the adult Chinese population) was used to estimate annual CHD and stroke event rates in China from 2010 to 2030 using simulations based on aging and population growth alone and, in addition, based on projected changes in systolic blood pressure, total cholesterol, diabetes, and smoking. Demographic changes expected to occur in China from 2010 to 2030 are forecasted to cause a rise of greater than 50% in annual CHD and stroke events. Much of the projected increase is due to aging and population growth alone. Additional events are attributed to trends in systolic blood pressure, total cholesterol, diabetes, and smoking. Data for the model come from the International Collaborative Study of Cardiovascular Disease in Asia Study for risk-factor trends; various other Chinese studies for stroke incidence, mortality, and case-fatality rates; and the China Multiprovincial Cohort Study for stroke and CHD hazard ratios.

6 Increase in Age-Standardized Mean Total Cholesterol Levels in Asia 1980-2008
Men Women Global mean total cholesterol levels changed little between 1980 and 2008, decreasing by less than 0.1 mmol/L per decade in men and women. In contrast, in East and Southeast Asia and the Pacific region, mean total cholesterol levels in men (shown on the left) and women (shown on the right) were estimated to increase by 0.08 and 0.09 mmol/L per decade, respectively, from 1980 to 2008. Trends in mean serum cholesterol were determined in an analysis of data from published and unpublished health surveys and epidemiologic studies from 199 countries and territories in 21 subregions, which were grouped into 7 merged regions.

Epidemiological studies show that lowering plasma cholesterol levels results in a progressive decrease in cardiovascular events.1-4 Combined data from the Air Force/Texas Coronary Atherosclerosis Prevention Study (AFCAPS/TexCAPS) and West of Scotland Coronary Prevention Study (WOSCOPS) trials suggest that reducing cholesterol levels from 285 mg/dL to 190 mg/dL decreases the incidence of CHD events from 170/1,000 patients in 10 years to 70/1,000 patients in 10 years.3,4 Physicians today are under increasing pressure to attain LDL-C goals below 100 mg/dL,5 and these targets could be reduced still further in the light of findings from ongoing clinical trials. Statins can achieve LDL-C reductions of up to 50–60% when used in high doses,6 however, statins in monotherapy are unable to reduce LDL-C levels beyond this level, leaving many hypercholesterolaemic patients at significant risk of coronary events. Strategies that combine lipid modifying agents with complementary mechanisms of action may further enhance the benefits of statin therapy.7 References 1. Castelli WP.

Baseline 1 year 2 years Additional Findings No correlation between CRP and LDL-C reduction Significant correlation between decrease in CRP and reduction in IMT (r =.13; P=.03) Patients in the highest tertile of change in CRP had the greatest mean reduction in IMT -50 -40 -30 -20 -10 14.0 19.7 Change (%) P<.001 P<.022 In ASAP, atorvastatin 80 mg reduced CRP significantly more than simvastatin 40 mg. At 1 year, the median percent change in CRP was 44.9% with atorvastatin and 14.0% with simvastatin (P<.001). By 2 years, the median percent change was 40.1% with atorvastatin and 19.7% with simvastatin (P<.022)1 There was no correlation between reductions in CRP and LDL-C. However, decreases in CRP were significantly correlated with reductions in IMT (r =.13; P=.03)1 Patients in the highest CRP tertile experienced the greatest mean reduction in IMT1 Reference: 1. van Wissen S, Trip MD, Smilde TJ, et al.

Planned follow-up was 5 years and the primary end point of this study was nonfatal MI and fatal CHD1 Untreated hypertension was defined as systolic blood pressure 160 mm Hg and/or diastolic blood pressure of 100 mm Hg; treated hypertension was defined as systolic blood pressure 140 mm Hg and/or diastolic blood pressure  90 mm Hg. Additional CVD risk factors included left-ventricular hypertrophy or other specified abnormalities on electrocardiogram, type 2 diabetes, peripheral arterial disease, previous stroke or transient ischemic attack, male sex, age 55 years or older, microalbuminuria or proteinuria, smoking, plasma TC:HDL-C ratio of 6 or higher, and a family history of premature CHD1 At baseline, patients had mean LDL-C levels of 131 mg/dL and a mean blood pressure of 164/95 mm Hg. Concurrent treatment of hypertension over the course of the trial reduced blood pressure to 138/80 mm Hg1 Reference: 1. Sever PS, Dahlof B, Poulter NR, et al.

15 PROVE IT: Study Design Patient population Men and women aged 18 years
Hospitalized within 10 days of acute MI or high-risk unstable angina (UA) TC 240 mg/dL Stable condition, enrolled after percutaneous coronary intervention (PCI), if planned Atorvastatin 80 mg (n=2099) 4162 patients Pravastatin 40 mg (n=2063) The PROVE IT clinical trial (supported by Bristol-Myers Squibb and Sankyo) compared the effectiveness of high-dose, intensive therapy with atorvastatin (80 mg) with that of standard-dose pravastatin (40 mg) in reducing the incidence of death and major coronary events in patients who had been hospitalized for an ACS (acute MI with or without ST-segment elevation or high-risk unstable angina) within the preceding 10 days. Patients were required to have cholesterol levels 240 mg/dL and to be in stable condition enrolled after percutaneous revascularization, if planned. Median LDL-C at baseline was 106 mg/dL1 Eligible patients were randomly assigned to receive either high-dose atorvastatin (80 mg) or standard-dose pravastatin (40 mg) and then followed up for 18 to 36 months. The primary efficacy measure was the time from randomization until the occurrence of a first major cardiac event—death from any cause, MI, documented unstable angina requiring rehospitalization, revascularization, or stroke1 Reference: 1. Cannon CP, Braunwald E, McCabe CH, et al. Comparison of intensive and moderate lipid lowering with statins after acute coronary syndromes.

There was a steady increase in the protective benefits of intensive atorvastatin therapy, demonstrated by a 33% reduction in death, MI, or urgent revascularization relative to standard pravastatin treatment by day 30, suggesting an early benefit to treatment with atorvastatin 80 mg versus pravastatin 40 mg1 Reference: 1.

Atorvastatin parent molecule CH3 CH3 O CH O OH - .. NHC N Active ortho-hydroxy-atorvastatin metabolite F 70% of the activity of atorvastatin is attributed to active metabolites Site* H H H3C Atorvastatin is a synthetic lipid-lowering agent that is administered as the calcium salt of the active hydroxy acid (parent molecule).1 After administration, atorvastatin is rapidly absorbed and metabolized to the active hydroxylated metabolites, and peak plasma concentrations occur in 1 to 2 hours. Approximately 70% of atorvastatin’s activity is attributed to the active metabolites The o-hydroxy group, which is unique to the active atorvastatin metabolite, has been shown to protect LDL-C from oxidation1 Reference: 1.

18 What Accounts for the Added Benefits of Atorvastatin?
Endothelial effects Anti-inflammatory effects Antioxidant effects Reduction in plaque progression Plaque stabilization + Reduction of lipids In addition to reducing LDL-C concentrations, atorvastatin may delay the development of atherosclerosis via endothelial, anti-inflammatory, or antioxidant effects, or by reducing plaque progression or promoting plaque stabilization Wassmann S, Nickenig G.

Pravastatin and atorvastatin produced parallel regression lines. However, for any degree of reduction in LDL-C, the progression rate was lower with atorvastatin than with pravastatin. The investigators suggested that this added benefit with atorvastatin was equivalent to an additional 20% reduction in LDL-C. Data such as these suggest that, although LDL-C plays a central role in the progression of atherosclerosis, improved outcomes with atorvastatin are not due to intensive LDL-C lowering alone1 Reference: 1.
