Statins use in ACS patients with very low baseline LDL-c; is it worth it?
The benefits of statins in ACS patients with baseline LDL-c below guideline targets are not well documented and remain controversial. A low LDL-c is not an uncommon finding in Asian patients. The large Chinese ACS registry (CPACS - Clinical Pathways for Acute Coronary Syndromes) was used for this analysis and 16% of the included patients had a baseline LDL-c < 70 mg/dl. Chinese ACS patients with LDL-c <70 mg were included, comparing patients that used a statin with patients that did not. They were matched using an extensive propensity score modeling. Patients were diagnosed with STEMI (34,53%), NSTEMI (13.16%) and UA (52,31%). Of the total 3374 patients, 2879 (85%) used a statin. Mean LDL-c was 55.61 mg/dl in the statin group and 54.57 mg/dl in patient that did not use a statin. Atorvastatin 20 mg was the most prescribed statin and <3% used atorvastatin ≥40 mg. Mace rates as well as cardiac deaths and all-cause mortality were significantly higher in the patients that were not prescribed statins. The HR for MACE in statin users vs non users was 0.61 (0.40-0.94). The HR’s of patients using the equivalent of 5-10 mg atorvastatin and patients using ≥20 mg was 0.61(0.40-0.94) and 0.53(0.34-0.84) respectively. The authors concluded that using low to moderate dose statin in Chinese ACS patients resulted in significant lower MACE ‘s and total mortality, 12 months after the initiating event. To build and expand this observational evidence larger randomized trials, that include the use of higher statin dosages, need to be designed and executed.

The future of personalized lipid management of CKD patients
In this updated review on the use of statins in chronic kidney disease patients (CKD), the authors discuss the dilemma’s that clinicians face when caring for patients with impaired renal function. Although 4 large studies, the 4 D study and the AURORA trial failed to show benefits in end stage CKD/hemodialysis patients, benefits have been observed in less advanced CKD patients as well an increased risk of harm or improved outcomes in patients with specific genetic, ethnic or metabolomic characteristics. Potential options to personalize the use of statins in certain CKD patients reviewed. Meta-analysis of statin trials and subgroups in the large clinical outcome trials like JUPITER, SHARP and IMPROVE-IT showed improved outcomes in sub groups of patients that were treated with statins or statin + ezetimibe. Co-morbidities, including impaired renal function, and/or concomitant medication, increase the risk for statin related side effects. The same was found for specific genetic polymorphisms of proteins involved in statin metabolism and/or trans-membrane transport of a broad range of molecules including statins. Racial related factors have gained importance in relationship to statin plasma concentration and related side effects. Asian ancestry increases the risk of statin side effects. African ancestry was shown to impact baseline CPK concentrations, and the observed higher CPK levels are not associated with muscle related damage. Non-statin drugs as ezetimibe, fibrates and PCSK9ab reduced CVD risk in subgroups of patients with impaired renal function. Future targets such as improving HDL efflux and other functional indices are being explored. Oxidative stress reflected by MPO concentrations is another attractive new target to reduce CVD risk in CKD patients. Finally metabolomics are suggested as a innovative and promising technique to personalize risk estimation and response to lipid lowering drugs in the future.

For primary prevention which patients benefit from using a statin and who don’t?
The use of statins in a primary prevention setting is less clear as in patients who suffered CVD complications. Baseline risk estimation is needed to distinguish those were statins could reduce risk and those were benefits might be counter balanced by statin associated harms e.g. DM type 2. In this retrospective observational analysis of the Israeli Maccabi Healthcare Services (MHS), medical data of >2 million patients was re-evaluated. For this analysis the authors selected 265 414 patients not using statins, and without CVD or DM, at least 2 year prior to the index date of 2010 and that had at least one statin prescription between January 1st, 2010 and December 31st, 2014. Individual CVD risk was calculated using the ESC based SCORE risk tables. Patients were stratified into 3 cohorts: low risk: ≤1% intermediate risk: 1-5% and high risk ≥5%. Statins were used by 17.9% of the selected individuals. Between 2010 and 2014, 5157 (1.9%) patients had a CVD event and 11 637 (4.4%) patients developed diabetes. Those that used low-intensity statin, with over 50% adherence, were more likely to develop diabetes if their CVD risk was low or intermediate. This was not the case for patients in the high CVD risk category. No CVD benefit was observed in the low risk category; their number needed to harm (NNH; incident DM) was 40. For the intermediate and high-risk categories, the NNH were 50 and 200 respectively while the NNT were 125 and 29. The authors concluded that based on their 4-year observational period, prescribing low dose statins to patients at low CVD risk was not associated with benefit and increased risk of harm. Patient that were categorized as high CVD risk benefitted from the use of low dose statins. In the intermediate risk category individualizing treatment choices were in line with current guideline recommendations.

Elevated TG, a high price to pay!
Addressing risk or risk factors beyond LDL-c is becoming the next challenge when we aim to further reduce CVD risk in statin treated patients. Triglycerides have re-surfaced not only as an important predictive CVD risk factor but also a lipid fraction that can be effectively reduced. The authors of this study re-analyzed data collected in the US Kaiser Permanente registries accessing almost 5 million patients. The selected patients were 45 years or older received statin mon-therapy, had and LDL-c 40-100 mg/dl, triglycerides < 500 mg/dl and a medical history of MI, stroke, ACS or PAD. Patients were divided in two groups: TG 200-499 mg/dl (N= 2 702) and TG <150 mg/dl (N= 14 481). Starting point of the first measurement was 2010 and patients were followed until December 2016, with a maximum follow-up period of 6.5 years. Total medical costs were calculated using proprietary data and validated methods. Adjustments were made for numerous relevant factors such as age, gender, ethnicity, study site etc. Patients with high TG were more frequently admitted to hospital for complications or care; Overall 13% more admissions (P<0.001). Outpatient costs were 5% higher (P=0.035) even after adjusting for co-morbidities such as diabetes and CKD. Emergency care cost were 6% greater as well and hospital ambulatory costs increased 25% in the high TG group. This translated in an annual cost increment of $964 per patient, per year. For the complete cohort of 2 702 patients, the total extra costs accrued to $2.6 million per year and to $13.5 million covering the total mean follow up of 5.2 years. The authors concluded that their results illustrate how relevant moderately elevated triglycerides are and that (new) therapies, able to effectively and safely reduce TG’s could lead to improved outcomes and potential cost savings as well.

Statins prevent amputations and deaths in PAD patients
Risks for mortality and rapid progression existing peripheral artery disease are high in patients that need revascularization for chronic limb threatening ischemia (CLTI). In this analysis of the Swedish National Registry for Vascular Surgery (Swedvasc) combined with a number of other National Swedish medical registries, patients revascularized for CLTI were evaluated for ensuing medical complications, including death, as well as co-morbidities and medications. Median follow up in this cohort was 1.6 years. The most important independent predictors for amputation and death were male gender HR 1.20 (1.09-1.33) renal insufficiency HR 1.57 (1.32-
1.87); diabetes HR 1.45 (1.32-1.60) and heart failure HR 1.17 (1.05-1.31). Reduced amputation rates were observed in patients using statins HR 0.71 (CI 0.64-0.78) and low dose acetylsalicylic acid HR 0.77, (0.70-0.86). The combined endpoint of amputation or death showed similar trends of risks; male sex HR 1.25 (1.18-1.32); renal insufficiency HR 1.94 (1.75-2.14), heart failure HR 1.50 (1.40-1.60) and diabetes HR 1.31 (1.23-1.38). Lower rates were observed when patients used statins HR 0.74 (0.67-0.82) and low dose aspirin HR 0.82 (0.77-0.88). The authors concluded that renal insufficiency is the most important risk factor for amputation and amputation/death, followed by diabetes and heart failure. Male patients with CLTI did worse than their female counterparts. And the improved outcomes in patients treated with statins and aspirin emphasize the importance of these CVD risk reducing medications in these very high risk patients.
