LAI 2016 Statement: Both LDL-C/Non-HDL-C goals are important in Indian context

Journal of The Association of Physicians of India March 2016 supplement

Clinical Conditions where Lipid Lowering therapy requiredA. Patients with ASCVDB. Patients undergoing PCIC. Primary prevention of CVD for DMD. Patients with low HDL-CE. For patients with CKDF. For patients with very high LDL-C (> 190

Statin For Secondary PreventionCurrent guidelines recommend moderate to high

dose of statins for secondary prevention.Atorvastatin has multiple landmark trials for

secondary prevention

Amongst all statins, Atorvastatin has robust evidence for secondary prevention of ASCVD

Higher dose atorvastatin has shown incremental benefits over and above those expected with lower dose statins

Among patients with ACS undergoing PCI, pretreatment with atorvastatin 80 mg improves clinical outcomes, driven mainly by reduction in periprocedural MI

383 patients with stable angina (53%) or NSTMI(47%) and chronic statin therapy undergoing PCI were randomized to atorvastatin reload (80 mg 12 h before PCI , + 40-mg pre-PCI) or placebo. All patients received long-term atorvastatin thereafter (40 mg/day). Primary end point : 30-day MACE (cardiac death, myocardial infarction, or unplanned revascularization)

Reloading with high-dose atorvastatin resulted in 50% reduced risk of MACE at 30 days versus placebo

These findings support strategy of routine reload with high-dose atorvastatin early before intervention even in the background of chronic therapy.

Collaborative Atorvastatin Diabetes Study – Performed in patients without CVD

28th Feb 2012: FDA Drug Safety Communication:

Important safety label changes to cholesterol-lowering statin drugs Increases in HbA1c and fasting serum glucose

levels have been reported with statin use

www.fda.gov

EFFECT ON BLOOD GLUCOSE LEVELS

A 2016 analysis estimated that high-dose statin therapy (eg, atorvastatin 40 mg daily) would lead to 50 to 100 new cases of diabetes in 10,000 treated individuals.

Effect on Blood Sugar LevelsStatins could have effects on glucose

metabolism that might influence the development of diabetes mellitus in non-diabetics or affect glycemic control in patients with existing diabetes.

A 2011 meta-analysis of five randomized trials (N = 32,752) also found an increased risk of incident diabetes with intensive statin therapy compared with moderate statin therapy

Consider risk Vs benefit

Pitavastatin in T2DM:No glycemic disturbances

T2DM patients were treated by Atorvastatin 10 mg (n=99), pravastatin 10 mg (n=85) and pitavastatin 2 mg (n=95) for 3 months.

Pitavastatin does not increase FPG and HbA1c in T2DM patients even in long

Pitavastatin is a good option for long term treatment in T2DM patients

Pitavastatin's ability to significantly and continually increase HDL-C levels over time suggests a particular benefit for patients with low baseline levels of HDL-C and/or those that fail to increase their HDL-C levels

using alternative statins.

Shifting from other statins to Pitavastatin further increases HDL-C

Upto 29% of patients on statin develops muscle related symptoms

LAI estimate – 10 – 15%. 75% of cases in first 3 months, 90% in first 6 months

Re-challenge with different statin is important if symptoms disappear

Pitavastatin For Statin Intolerant Patients: Study 1In Florida, USA, 152 patients intolerant to > 2

previous statins due to myopathy (average 2.7 statins) were placed on pitavastatin therapy.

Percentage (%) of patients tolerating pitavastatin and achieving NCEP ATP-III LDL-C goal non-HDL-C goal were measured

104 patients (76%) patients tolerated pitavastatin therapy and continued it for > 6 months

87% of patients with intermediate CV risk achieved their NCEP-ATP III LDL-C goals with pitavastatin therapy

Journal of Clinical Lipidology 2012: 6(3) : 274

Pitavastatin is a good option for those who cannot tolerate other

statins

Pitavastatin For Statin Intolerant Patients: Study 2

In a study, 148 patients who had history of > 2 statin intolerance were prescribed pitavastatin.

104 patients who tolerated pitavastatin > 6 weeks were followed up for 1 year to detect long term tolerance of pitavastatin

Results: 80.1% of the patients were still tolerating pitavastatin after 1 year use.

79% of patients who tolerated pitavastatin reached NCEP LDL goal

Journal of Clinical Lipidology 2013;7(3):264

Conclusions Pitavastatin is well tolerated by

majority of statin intolerant patients

Pitavastatin For Statin Intolerant Patients: Study 3

A study presented in ACC 2013 conference40 patients (USA) who were intolerant to other statins

were treated with pitavastatin 2 mg27 (68%) patients could tolerate pitavastatin for > 3

monthsLDL-C was reduced by 34% (from 147 mg/dl to 93

mg/dl)Conclusion: Low dose pitavastatin is an acceptable

alternative to abandoning statin among 2/3rd of patients documented to be intolerant to other statins, providing an average LDL-C reduction of 34%.

Choline fenofibrate Only fenofibrate that do not require activation from the liver Only fenofibrate with predictable bioavailability (81%) Dose is 135 mg/day, lower than micronized and nanoparticle

fenofibrate Can be taken with or without food As per Indian consensus statement for dyslipidemia 2014, It

is only preparation of fenofibric acid recommended for use at present.

Long term choline fenofibrate + statin well tolerated

93% patients completed 116 wks study The combination resulted in sustained improvement in

HDL-C (+17.4%), TG (−46.4%) and LDL-C (−40.4%).

No deaths/treatment-related serious adverse events Discontinuation due to adverse events was 2.9% Rhabdomyolysis was not reported in any group

Conclusion: choline fenofibrate is safe for combination with statin (moderate dose) for long term use

Primary Prevention – Who To Treat

• It may be most appropriate to view lipid-lowering therapy with statins as an intervention that can reduce relative cardiovascular (CV) risk by approximately 20 to 30 percent regardless of baseline low-density lipoprotein cholesterol (LDL-C)

• The absolute benefit of treatment will be proportional to the underlying absolute risk.

• Use a risk calculator like the Framingham Risk score.• Moderate intensity best – 20 mg Atorva, 5 – 10 mg

Rosuvastatin
