A set of pharmacological mechanisms suggests that the use of statin medications may be stimulating the development of atherosclerosis and chronic heart failure. Japanese and American researchers have documented the mechanisms by which statin medications may be causing coronary artery calcification. They propose that the guidelines regulating the use of statin medications be critically re-evaluated [Okuyama 2015].
If the researchers are correct, then, yes, statin medications do reduce total cholesterol and bad cholesterol levels. However, statin medications may not reduce the incidence of coronary heart disease. Furthermore, statin medications may be at least partially responsible for the increased incidence of chronic heart failure that has been observed in the period since statin medications were introduced in 1987.
