This significant effect was derived by the use of fibrates ( RR 0.80 , 95 % CI 0.73–0.87 , P < 0.001 , I2 = 22 % ) and meta-regression analysis showed that this benefit was consistent with an absolute reduction in low-density lipoprotein cholesterol .
Meta-regression analyses failed to demonstrate a significant association of pharmacologically increased high-density lipoprotein cholesterol with key endpoints .
Conclusion The use of high-density lipoprotein cholesterol modifying treatments had no significant effect on cardiovascular mortality , stroke or all-cause mortality .
The beneficial effect on myocardial infa rct ion was lost when drugs were used with statin therapy
Background The effects of increasing high-density lipoprotein cholesterol on cardiovascular outcomes remain uncertain .
Design We conducted a meta- analysis to investigate the effects of high-density lipoprotein cholesterol modifiers ( niacin , fibrates and cholesteryl ester transfer protein inhibitors ) on cardiovascular outcomes .
High-density lipoprotein cholesterol and cardiovascular disease. Four prospective American studies.
The British Regional Heart Study ( BRHS ) reported in 1986 that much of the inverse relation of high-density lipoprotein cholesterol ( HDLC ) and incidence of coronary heart disease was eliminated by covariance adjustment . Using the proportional hazards model and adjusting for age , blood pressure , smoking , body mass index , and low-density lipoprotein cholesterol , we analyzed this relation separately in the Framingham Heart Study ( FHS ) , Lipid Research Clinics Prevalence Mortality Follow-up Study ( LRCF ) and Coronary Primary Prevention Trial ( CPPT ) , and Multiple Risk Factor Intervention Trial ( MRFIT ) . In CPPT and MRFIT ( both r and omized trials in middle-age high-risk men ) , only the control groups were analyzed . A 1-mg/dl ( 0.026 mM ) increment in HDLC was associated with a significant coronary heart disease risk decrement of 2 % in men ( FHS , CPPT , and MRFIT ) and 3 % in women ( FHS ) . In LRCF , where only fatal outcomes were documented , a 1-mg/dl increment in HDLC was associated with significant 3.7 % ( men ) and 4.7 % ( women ) decrements in cardiovascular disease mortality rates . The 95 % confidence intervals for these decrements in coronary heart and cardiovascular disease risk in the four studies overlapped considerably , and all contained the range 1.9 - 2.9 % . HDLC levels were essentially unrelated to non-cardiovascular disease mortality . When differences in analytic methodology were eliminated , a consistent inverse relation of HDLC levels and coronary heart disease event rates was apparent in BRHS as well as in the four American studies
