Statins Benefits

Statins─ The Miracle Medicine of the Millennium

• Statins are a group of medicines used to decrease the amount of cholesterol produced by the body and have revolutionized the treatment of elevated cholesterol. In 2007 Robert Shook identified statins as one of the seven lifesaving miracle medicines that “stave off death.”

• Statins have the ability to lower the risk of heart attack, stroke and CARPs (coronary artery revascularization procedures such as angioplasty, stent or bypass surgery) by 25-50% depending upon the magnitude of LDL-C reduction achieved. Statin therapy reduces mortality and morbidity even in patients with pretreatment LDL-C levels as low as 60-100 mg/dL and is greatest in those who achieve an LDL-C lower than 50mg/dl.1-3 The LDL-C lowering efficacy of various statins is given in Table 029.

• Statins have been in clinical use for two decades and its market share in the US alone is $26billion-per year. Since the pioneering Scandinavian Simvastatin Survival Study (4S) trial, which showed that simvastatin reduced mortality in patients with a high cardiovascular risk, many large outcome trials of statins have been done in people with and without heart disease and also in people with and without high LDL-C.1

• Newly initiated statin therapy is associated with rapid regression of coronary atherosclerosis within 2 months. These results provide insight into the rapid clinical benefits of statin therapy after an ACS (acute coronary syndrome).4 Greater decreases in total cholesterol to HDL-C (TC/HDL) ratio were associated with greater decrease in plaque volume.4

• Several studies have clearly demonstrated the unequivocal benefits of statins. Rates of heart attack, stroke, and coronary revascularizations are typically reduced by a third and possibly as high as two-thirds when LDL-C is lowered to near optimal levels.3, 5, 6

• The promise of statins is enormous, but just as heart disease risk factors work in tandem so statins need to be combined with lifestyle changes for optimal benefits. Statin treatment resulted in >40% reduction all-cause and cardiac mortality in the very elderly survivors of heart attack.7 Studies of intensive LDL-C lowering with statins in ACS patients, targeting LDL40 years of age by the AHA (American Heart Association) and ADA (American Diabetes Association), regardless of the baseline lipid levels. The clear benefits of statin therapy in patients with diabetes are in sharp contrast to the lack of benefit of aspirin in primary prevention of CVD (cardiovascular disease) in diabetic patients.1

• The lipid-modifying effects of statin therapy on LDL-C and HDL-C among South Asian patients is similar to those of Europids unlike other Asians who have a greater efficacy.11, 12 See Intensive Statin Therapy for Indians.

• Despite its enormous benefits, statins are underutilized worldwide especially in the elderly, women, young adults, and children.13

Statins and other lipids

• Statins increase HDL-C levels up to 10% and increase the most protective HDL-C (large α-1 HDL particles) up to 36%. Moreover, statins decrease the harmful HDL-C (preβ-1 HDL particles) levels up to 40%. The efficacy of the different statins regarding beneficial HDL particle alteration in decreasing order is rosuvastatin, atorvastatin, simvastatin, pravastatin, and lovastatin.14, 15 It generally follows the same order as LDL lowering efficacy.

• All statins lower triglycerides (TG) in a similar magnitude as LDL-C reduction (1:1) where TG levels are elevated. Accordingly statins are highly effective in lowering non-HDL cholesterol, the secondary target of treatment in people with TG

• High dose of potent statins allow achievement of LDL-C targets but not always achieved. In one study, LDL-C goal (

Statins and Ethnicity

• Plasma exposure to rosuvastatin and its metabolites was significantly higher in Chinese, Malay, and Asian-Indian subjects compared with white subjects living in the same environment.18
