Exercise & Statins Take Home Messages

1. Exercise Magnifies “Statin” Myalgia2. Exercise Causes & Magnifies Many of The

CK Elevations Attributed to Statins 3. Some Patients Report Weakness, But

There is Little Objective Data on Muscle in Asymptomatic Patients

4. Statins Appear to Block the Aerobic Training Response

5. Long Term Muscle Effects of Statins Are Not Defined


1. Exercise Magnifies “Statin” Myalgia

Collected Cases

• Among 22 Professional Athletes• With LDL Receptor Defects• Only 6 Could Tolerate Statins• Despite Multiple Attempts With Fluva,

Lova, Prava, Atorva, & Simva

Sinzinger Br J Clin Phar 2004

orPRIMO Study

• 7,924 French Patients on Fluva 80, Atorva 40-80, Prava 40, Simva 40-80, for 3 mos

• 10.5% Reported Muscular Symptoms

Bruckert CV Drugs & Therapy 2005

PRIMO Study• 10.5% Reported Muscular Symptoms• The Rate was 14.7% in Patients

Practicing “Intense Form of Sport” vs 10.8% Who Did “Only Leisure Time Activities”

• Pain Was Triggered in 41% - 53% by “Unusual Physical Activity”

Bruckert CV Drugs & Therapy 2005



CK Elevations Attributed to Statins

Exercise ALONE Can Produce Remarkable CK Increases

So That Many CK Increases Attributed to Statins Are Due to

Exercise

Elevations Attributed to Statins 3. Some Patients Report Weakness, But There is

Little Objective Data on Muscle Strength

Weakness is Not An Uncommon Complaint…Complaints of

Decreased Exercise Tolerance Are Uncommon

Current Opinion in Lipidology 2010

• 6 Studies Examined Statins & Muscle Strength

• 9 Studies Examined Statins & Exercise Tolerance

• Studies Were Small & Used Crude Measues• Insufficient Data to Determine if Statins

Affect Strength and Exercise Performance

Study Definition of Statin-Related Myopathy

1. They report new or increased myalgia, cramps, or muscle aching,

2. These symptoms have persisted for at least 2 weeks,

3. The symptoms resolve within 2 weeks of stopping the study drug, and

4. The symptoms reoccur within 4 weeks of restarting the medication

Do Statins Cause Diabetes ?

• Jupiter Trial - 20 of Rosuva v. Placebo• CRP > 2….in 17,603 Subjects• Among Those with Diabetes Risk Factors

(Metabolic S, Fasting Glucose > 100, BMI > 30, A1c > 6)…Risk Increased 25% (5-49%)

• New Diabetics: 270 v 216….54 More New Diabetics• But…39% < CV Events, 36% < VTE, 18% < Deaths

!!!!• 134 < CV Events vs 54 New Diabetics in 17,603

Subjects• If No DM Risk Factors, No New Diabetes

Lancet 380: 565, 2012

Jupiter is not the First or Last

Why Diabetes ?

Something Is Going On In the Muscle

Statins Decrease P13k / AktIncreasing the Forkhead Box Gene Group (FOXO)FOXO Increases the 2 Muscle SpecificUbiquitin E3 Ligases

Mu Atrophy F Box (MAFbx)Mu RING Finger –1 (MURF-1)

They Conjugate to Protein SubstrateInitiating Protein Degradation

FOXO Also Activates Pyruvate Dehydrogenase Kinase (PDK) TranscriptionUpregulating PDK Inactivates Muscle Pyruvate Dehydrogenase Complex.Which Limits CHO & Promotes Fat Oxidation.




There is Little Objective Data on Muscle in Asymptomatic Patients
