Dr Jessica Leuschen (Wilford Hall Ambulatory Surgery Center
San Antonio TX) and colleagues point out a 15 increased risk
of cataracts with statin use in a military healthcare system
published in october 2013 (JAMA Ophthalmology)
At the recent European Society of Cardiology(ESC) 2013
Congress Dr John B Kostis (Rutgers Robert Wood Johnson
Medical School New Brunswick NJ) presented the results of
a random-effects meta-analysis showing a 20 lower rate of
cataracts with statin use compared with no statin use with a
more pronounced benefit seen when statins were started in
younger patients

All 9 polymorphisms were associated with a highly consistent reduction in the risk of CHD per unit lower LDL-C with no evidence of heterogeneity of effect (I(2) = 00) In a meta-analysis combining nonoverlapping data from 312321 participants naturally random allocation to long-term exposure to lower LDL-C was associated with a 545 (95 confidence interval 488 to 595) reduction in the risk of CHD for each mmoll (387 mgdl) lower LDL-C This represents a 3-fold greater reduction in the risk of CHD per unit lower LDL-C than that observed during treatment with a statin started later in life (p = 843 times 10(-19)) CONCLUSIONS Prolonged exposure to lower LDL-C beginning early in life is associated with a substantially greater reduction in the risk of CHD than the current practice of lowering LDL-C beginning later in life

All 9 polymorphisms were associated with a highly consistent reduction in the risk of CHD per unit lower LDL-C with no evidence of heterogeneity of effect (I(2) = 00) In a meta-analysis combining nonoverlapping data from 312321 participants naturally random allocation to long-term exposure to lower LDL-C was associated with a 545 (95 confidence interval 488 to 595) reduction in the risk of CHD for each mmoll (387 mgdl) lower LDL-C This represents a 3-fold greater reduction in the risk of CHD per unit lower LDL-C than that observed during treatment with a statin started later in life (p = 843 times 10(-19)) CONCLUSIONS Prolonged exposure to lower LDL-C beginning early in life is associated with a substantially greater reduction in the risk of CHD than the current practice of lowering LDL-C beginning later in life

OBJECTIVES The purpose of this study was to estimate the effect of long-term exposure to lower plasma low-density lipoprotein cholesterol (LDL-C) on the risk of coronary heart disease (CHD) METHODS We conducted a series of meta-analyses to estimate the effect of long-term exposure to lower LDL-C on the risk of CHD mediated by 9 polymorphisms in 6 different genes We then combined these Mendelian randomization studies in a meta-analysis to obtain a more precise estimate of the effect of long-term exposure to lower LDL-C and compared it with the clinical benefit associated with the same magnitude of LDL-C reduction during treatment with a statin

All 9 polymorphisms were associated with a highly consistent reduction in the risk of CHD per unit lower LDL-C with no evidence of heterogeneity of effect (I(2) = 00) In a meta-analysis combining nonoverlapping data from 312321 participants naturally random allocation to long-term exposure to lower LDL-C was associated with a 545 (95 confidence interval 488 to 595) reduction in the risk of CHD for each mmoll (387 mgdl) lower LDL-C This represents a 3-fold greater reduction in the risk of CHD per unit lower LDL-C than that observed during treatment with a statin started later in life (p = 843 times 10(-19)) CONCLUSIONS Prolonged exposure to lower LDL-C beginning early in life is associated with a substantially greater reduction in the risk of CHD than the current practice of lowering LDL-C beginning later in life

OBJECTIVES The purpose of this study was to estimate the effect of long-term exposure to lower plasma low-density lipoprotein cholesterol (LDL-C) on the risk of coronary heart disease (CHD) METHODS We conducted a series of meta-analyses to estimate the effect of long-term exposure to lower LDL-C on the risk of CHD mediated by 9 polymorphisms in 6 different genes We then combined these Mendelian randomization studies in a meta-analysis to obtain a more precise estimate of the effect of long-term exposure to lower LDL-C and compared it with the clinical benefit associated with the same magnitude of LDL-C reduction during treatment with a statin

All 9 polymorphisms were associated with a highly consistent reduction in the risk of CHD per unit lower LDL-C with no evidence of heterogeneity of effect (I(2) = 00) In a meta-analysis combining nonoverlapping data from 312321 participants naturally random allocation to long-term exposure to lower LDL-C was associated with a 545 (95 confidence interval 488 to 595) reduction in the risk of CHD for each mmoll (387 mgdl) lower LDL-C This represents a 3-fold greater reduction in the risk of CHD per unit lower LDL-C than that observed during treatment with a statin started later in life (p = 843 times 10(-19)) CONCLUSIONS Prolonged exposure to lower LDL-C beginning early in life is associated with a substantially greater reduction in the risk of CHD than the current practice of lowering LDL-C beginning later in life

OBJECTIVES The purpose of this study was to estimate the effect of long-term exposure to lower plasma low-density lipoprotein cholesterol (LDL-C) on the risk of coronary heart disease (CHD) METHODS We conducted a series of meta-analyses to estimate the effect of long-term exposure to lower LDL-C on the risk of CHD mediated by 9 polymorphisms in 6 different genes We then combined these Mendelian randomization studies in a meta-analysis to obtain a more precise estimate of the effect of long-term exposure to lower LDL-C and compared it with the clinical benefit associated with the same magnitude of LDL-C reduction during treatment with a statin

All 9 polymorphisms were associated with a highly consistent reduction in the risk of CHD per unit lower LDL-C with no evidence of heterogeneity of effect (I(2) = 00) In a meta-analysis combining nonoverlapping data from 312321 participants naturally random allocation to long-term exposure to lower LDL-C was associated with a 545 (95 confidence interval 488 to 595) reduction in the risk of CHD for each mmoll (387 mgdl) lower LDL-C This represents a 3-fold greater reduction in the risk of CHD per unit lower LDL-C than that observed during treatment with a statin started later in life (p = 843 times 10(-19)) CONCLUSIONS Prolonged exposure to lower LDL-C beginning early in life is associated with a substantially greater reduction in the risk of CHD than the current practice of lowering LDL-C beginning later in life

OBJECTIVES The purpose of this study was to estimate the effect of long-term exposure to lower plasma low-density lipoprotein cholesterol (LDL-C) on the risk of coronary heart disease (CHD) METHODS We conducted a series of meta-analyses to estimate the effect of long-term exposure to lower LDL-C on the risk of CHD mediated by 9 polymorphisms in 6 different genes We then combined these Mendelian randomization studies in a meta-analysis to obtain a more precise estimate of the effect of long-term exposure to lower LDL-C and compared it with the clinical benefit associated with the same magnitude of LDL-C reduction during treatment with a statin

All 9 polymorphisms were associated with a highly consistent reduction in the risk of CHD per unit lower LDL-C with no evidence of heterogeneity of effect (I(2) = 00) In a meta-analysis combining nonoverlapping data from 312321 participants naturally random allocation to long-term exposure to lower LDL-C was associated with a 545 (95 confidence interval 488 to 595) reduction in the risk of CHD for each mmoll (387 mgdl) lower LDL-C This represents a 3-fold greater reduction in the risk of CHD per unit lower LDL-C than that observed during treatment with a statin started later in life (p = 843 times 10(-19)) CONCLUSIONS Prolonged exposure to lower LDL-C beginning early in life is associated with a substantially greater reduction in the risk of CHD than the current practice of lowering LDL-C beginning later in life

OBJECTIVES The purpose of this study was to estimate the effect of long-term exposure to lower plasma low-density lipoprotein cholesterol (LDL-C) on the risk of coronary heart disease (CHD) METHODS We conducted a series of meta-analyses to estimate the effect of long-term exposure to lower LDL-C on the risk of CHD mediated by 9 polymorphisms in 6 different genes We then combined these Mendelian randomization studies in a meta-analysis to obtain a more precise estimate of the effect of long-term exposure to lower LDL-C and compared it with the clinical benefit associated with the same magnitude of LDL-C reduction during treatment with a statin

All 9 polymorphisms were associated with a highly consistent reduction in the risk of CHD per unit lower LDL-C with no evidence of heterogeneity of effect (I(2) = 00) In a meta-analysis combining nonoverlapping data from 312321 participants naturally random allocation to long-term exposure to lower LDL-C was associated with a 545 (95 confidence interval 488 to 595) reduction in the risk of CHD for each mmoll (387 mgdl) lower LDL-C This represents a 3-fold greater reduction in the risk of CHD per unit lower LDL-C than that observed during treatment with a statin started later in life (p = 843 times 10(-19)) CONCLUSIONS Prolonged exposure to lower LDL-C beginning early in life is associated with a substantially greater reduction in the risk of CHD than the current practice of lowering LDL-C beginning later in life

OBJECTIVES The purpose of this study was to estimate the effect of long-term exposure to lower plasma low-density lipoprotein cholesterol (LDL-C) on the risk of coronary heart disease (CHD) METHODS We conducted a series of meta-analyses to estimate the effect of long-term exposure to lower LDL-C on the risk of CHD mediated by 9 polymorphisms in 6 different genes We then combined these Mendelian randomization studies in a meta-analysis to obtain a more precise estimate of the effect of long-term exposure to lower LDL-C and compared it with the clinical benefit associated with the same magnitude of LDL-C reduction during treatment with a statin

All 9 polymorphisms were associated with a highly consistent reduction in the risk of CHD per unit lower LDL-C with no evidence of heterogeneity of effect (I(2) = 00) In a meta-analysis combining nonoverlapping data from 312321 participants naturally random allocation to long-term exposure to lower LDL-C was associated with a 545 (95 confidence interval 488 to 595) reduction in the risk of CHD for each mmoll (387 mgdl) lower LDL-C This represents a 3-fold greater reduction in the risk of CHD per unit lower LDL-C than that observed during treatment with a statin started later in life (p = 843 times 10(-19)) CONCLUSIONS Prolonged exposure to lower LDL-C beginning early in life is associated with a substantially greater reduction in the risk of CHD than the current practice of lowering LDL-C beginning later in life

OBJECTIVES The purpose of this study was to estimate the effect of long-term exposure to lower plasma low-density lipoprotein cholesterol (LDL-C) on the risk of coronary heart disease (CHD) METHODS We conducted a series of meta-analyses to estimate the effect of long-term exposure to lower LDL-C on the risk of CHD mediated by 9 polymorphisms in 6 different genes We then combined these Mendelian randomization studies in a meta-analysis to obtain a more precise estimate of the effect of long-term exposure to lower LDL-C and compared it with the clinical benefit associated with the same magnitude of LDL-C reduction during treatment with a statin

All 9 polymorphisms were associated with a highly consistent reduction in the risk of CHD per unit lower LDL-C with no evidence of heterogeneity of effect (I(2) = 00) In a meta-analysis combining nonoverlapping data from 312321 participants naturally random allocation to long-term exposure to lower LDL-C was associated with a 545 (95 confidence interval 488 to 595) reduction in the risk of CHD for each mmoll (387 mgdl) lower LDL-C This represents a 3-fold greater reduction in the risk of CHD per unit lower LDL-C than that observed during treatment with a statin started later in life (p = 843 times 10(-19)) CONCLUSIONS Prolonged exposure to lower LDL-C beginning early in life is associated with a substantially greater reduction in the risk of CHD than the current practice of lowering LDL-C beginning later in life

Two young women with total PCSK9 deficiency have been identified Both subjects had very low plasma levels of LDL-C (14 mgdl and 16 mgdl) No adverse clinical sequellae were reported in either individual Determining the long-term consequences of PCSK9 deficiency will require careful clinical assessment of additional older PCSK9-deficient individuals

OBJECTIVES The purpose of this study was to estimate the effect of long-term exposure to lower plasma low-density lipoprotein cholesterol (LDL-C) on the risk of coronary heart disease (CHD) METHODS We conducted a series of meta-analyses to estimate the effect of long-term exposure to lower LDL-C on the risk of CHD mediated by 9 polymorphisms in 6 different genes We then combined these Mendelian randomization studies in a meta-analysis to obtain a more precise estimate of the effect of long-term exposure to lower LDL-C and compared it with the clinical benefit associated with the same magnitude of LDL-C reduction during treatment with a statin

All 9 polymorphisms were associated with a highly consistent reduction in the risk of CHD per unit lower LDL-C with no evidence of heterogeneity of effect (I(2) = 00) In a meta-analysis combining nonoverlapping data from 312321 participants naturally random allocation to long-term exposure to lower LDL-C was associated with a 545 (95 confidence interval 488 to 595) reduction in the risk of CHD for each mmoll (387 mgdl) lower LDL-C This represents a 3-fold greater reduction in the risk of CHD per unit lower LDL-C than that observed during treatment with a statin started later in life (p = 843 times 10(-19)) CONCLUSIONS Prolonged exposure to lower LDL-C beginning early in life is associated with a substantially greater reduction in the risk of CHD than the current practice of lowering LDL-C beginning later in life

OBJECTIVES The purpose of this study was to estimate the effect of long-term exposure to lower plasma low-density lipoprotein cholesterol (LDL-C) on the risk of coronary heart disease (CHD) METHODS We conducted a series of meta-analyses to estimate the effect of long-term exposure to lower LDL-C on the risk of CHD mediated by 9 polymorphisms in 6 different genes We then combined these Mendelian randomization studies in a meta-analysis to obtain a more precise estimate of the effect of long-term exposure to lower LDL-C and compared it with the clinical benefit associated with the same magnitude of LDL-C reduction during treatment with a statin

All 9 polymorphisms were associated with a highly consistent reduction in the risk of CHD per unit lower LDL-C with no evidence of heterogeneity of effect (I(2) = 00) In a meta-analysis combining nonoverlapping data from 312321 participants naturally random allocation to long-term exposure to lower LDL-C was associated with a 545 (95 confidence interval 488 to 595) reduction in the risk of CHD for each mmoll (387 mgdl) lower LDL-C This represents a 3-fold greater reduction in the risk of CHD per unit lower LDL-C than that observed during treatment with a statin started later in life (p = 843 times 10(-19)) CONCLUSIONS Prolonged exposure to lower LDL-C beginning early in life is associated with a substantially greater reduction in the risk of CHD than the current practice of lowering LDL-C beginning later in life

Effect of long-term exposure to lower low-density lipoprotein cholesterol beginning early in life on the risk of coronary heart disease a Mendelian

OBJECTIVES The purpose of this study was to estimate the effect of long-term exposure to lower plasma low-density lipoprotein cholesterol (LDL-C) on the risk of coronary heart disease (CHD) METHODS We conducted a series of meta-analyses to estimate the effect of long-term exposure to lower LDL-C on the risk of CHD mediated by 9 polymorphisms in 6 different genes We then combined these Mendelian randomization studies in a meta-analysis to obtain a more precise estimate of the effect of long-term exposure to lower LDL-C and compared it with the clinical benefit associated with the same magnitude of LDL-C reduction during treatment with a statin

All 9 polymorphisms were associated with a highly consistent reduction in the risk of CHD per unit lower LDL-C with no evidence of heterogeneity of effect (I(2) = 00) In a meta-analysis combining nonoverlapping data from 312321 participants naturally random allocation to long-term exposure to lower LDL-C was associated with a 545 (95 confidence interval 488 to 595) reduction in the risk of CHD for each mmoll (387 mgdl) lower LDL-C This represents a 3-fold greater reduction in the risk of CHD per unit lower LDL-C than that observed during treatment with a statin started later in life (p = 843 times 10(-19)) CONCLUSIONS Prolonged exposure to lower LDL-C beginning early in life is associated with a substantially greater reduction in the risk of CHD than the current practice of lowering LDL-C beginning later in life
