Is a low dose atorvastatin on par with a high dose in Asians?
Are low dose high intensity statins just as protective and no need for higher dosages. In this study patients were randomized to atorvastatin 40-80 mg vs 20 mg. The 24 Chinese ACS / post PCI patients were followed for 9 months using OCT and lipoprotein + hs CRP measurement. Although both groups showed improved outcomes for all studied parameters including vulnerable plaque characteristics, patients allocated to the higher dosages of atorvastatin had significantly enhanced outcomes for all the studied parameters. The increase of the fibrous cap was more pronounced in the intensive-dose group vs the conventional-dose group 184.1±57.4 mm vs. 125.1± 28.6, P=.005). The lipid core arc was significantly decreased in both groups compared with baseline (72.9±29.3 vs. 127.6± 50.8, P<.01 and 74.6±32.9 vs. 132.6±51.3, P<.01, respectively). A inverse relationship between increased LDL-c plasma concentration and the thinnest fibrous cap as well as a direct correlation between hsCRP level and increased of the lipid core arc were observed as well. The, atorvastatin dose dependent, improvements of all studied parameters, is suggestive of the dual lipid lowering and anti-inflammatory effects of atorvastatin.

Low – lower - lowest is that right (or wrong)?
Should a patient with a low baseline LDL-c (< 70 mg/dl) be treated with lipid lowering drugs or is there no benefit or even harm to be expected? To answer this question the authors of this study re-analyzed the Cholesterol Treatment Trialist Collaboration (CTT) data for statins and explored Medline databases for non-statin drugs (ezetimibe and PCSK9ab). Randomized double blind controlled CVD outcome trials of persons with LDL-c averaging 70 mg/dl, were included in this analysis. The risk ratio (RR) of major vascular events (a composite of coronary heart death, myocardial infarction, ischemic stroke, or coronary revascularization) per 1-mmol/L (38.7-mg/dL) reduction in LDL-C level was calculated. For both separate as well as the combined treatments approaches, the RR per 1 mmol/L of LDL-reductions were 0.78-0.79 with slightly different 95% CI’s; for statins: 0.65-0.94; the 3 non-statins trials: 0.70-0.88 and for the combined analysis: 0.71-0.87; P < .001. More importantly no increase of serious adverse events was observed in patients in whom LDL-c levels were reduced to very low levels, reaching sometimes LDL-c concentrations of 0.5 mmol/L (21mg/dL). These results re-affirm that reducing LDL-c to levels beyond what is dictated in current guidelines, continues to reduce CVD risk; updated guidelines are likely to incorporate these findings in upcoming releases.

Diabetics, without CVD, remain healthier with lower LDL-c levels
In primary prevention the notion of achieving (very) low LDL-c is sometimes debated. For diabetic patients the impact of LDL-c levels on CVD risk is high-lighted in this retrospective Kaiser Permanente analysis (2006-2017) of 62 428 statin treated diabetic patients. Using a Cox multivariate data analyses to determine the HR’s for ASCVD events (myocardial infarction, ischemic stroke or coronary heart disease death. After a mean follow-up of 6 years, lower LDL-c or non-HDL-c levels consistently indicated a reduced CVD risk. A trend for LDL-c: p <0.0001 and for for non-HDL-c: p <0.0001. When comparing achieved LDL-c levels of >130 mg/dl to <50 mg/dl a HR of 0.58 (0.49-0.69) was observed. Similar reductions for Non-HDL-c, of >160 vs < 80 mg/dl; HR 0.59 (0.51-0.68). Despite these optimistic findings, the challenge of reaching these lower targets remains formidable, a majority of patients included in meta-analyses of statin trials were unable to reach LDL-c levels of < 70 mg/dl (>60%). Convincing doctors as well as patients to actively pursue these lower LDL-c or Non HDL-c targets as standard diabetes management strategies, requires more efforts to reach and update/educate both.

RCT Study in Chinese CSDH patients, re-affirms benefits of atorvastatin
The CVD benefits of (atorva)statin for post ischemic stroke patients has been substantiated in the SPARCL trial. The benefits (or harms) associated with a potential for increased bleeding risk remain controversial. Despite the increase of hemorrhagic strokes in the SPRACL study, accumulation observational studies show benefits of (atorva)statin in patients at risk for cerebral hemorrhagic complications. In this the Effect of Atorvastatin on Chronic Subdural Hematoma (ATOCH) study the use of atorvastatin showed improved outcomes as well This was a randomized, placebo-controlled, double-blind phase II clinical trial conducted in multiple centers in China from February 2014 to November 2015. The investigators invited 254 patients with Chronic Subdural Hematoma (CSDH), diagnosed with a CT scan; of these, 200 (78.7%) were enrolled in the trial. Patients were randomized to atorvastatin 20 mg or placebo for 8 weeks and followed for an additional 16 weeks. The primary outcome: change in hematoma volume (HV) measured (CT scan) after 8 weeks of treatment. The secondary outcomes were HV at 4th, 12th, and 24th weeks as well as neurological function that was evaluated using the Markwalder grading scale/Glasgow Coma Scale and the Barthel Index at 8th weeks. Baseline HV measurements were comparable between the two treatment arms. At 8 weeks HV reduction in the statin users (n=98) improved significantly (-12.55 mL) compared to the placebo group (N=98); -12,55 mL (-0.9 - -23.9 mL; p= 0.003). Neurological tests improved in 45 45.9%) statins users vs 28 (28.6%) of the placebo group, this translated into an OR of 1.957 (1.07-3.58; P=0.03) for neurological improvements associated with atorvastatin use. Post event complications, surgery for enlarging of hematoma or deteriorating clinical conditions were more frequent in the no statin users as well 11 (11.2%) vs 23 (23.5%); HR 0.47 (0.24-0.92; p=0.03). Patients using atorvastatin 20 mg for 8 weeks did not report an increased number of adverse events. The authors suggest that atorvastatin reduces hematomas, primarily by suppressing local Inflammation and reducing inflammation-induced vascular leakage as well as promoting angiogenesis. Atorvastatin could thus prevent the formation as well as accelerate the absorption of hematomas and quicken neurological improvements in CSDH patients. Using statins as an alternative to surgical management of CSDH patients, warrants a larger properly designed randomized placebo-controlled trial.

Heightened awareness needed for statin associated necrotizing myositis
Insights into the nature of the elusive statin associated myopathy is examined with the Australian Myositis Databases. Although most of reported the muscle related problems are benign and resolve when statins are stopped, Immune mediated idiopathic inflammatory myositis (IIM) and more specifically, the auto-antibody mediated necrotizing myositis is a serious complication, necessitating immunosuppressant medication for prolonged periods. Using a population-based case-control design of data collected in the South Australian Myositis database of histological confirmed cases of IIm diagnosed between 1990 – 2014 (N=221) and population-based controls form the North West Adelaide Health Study (N=662), matched by age and sex in a 3:1 ratio. The mean age of IIm cases was 62,2 and 59.7% were female. Statins were used by 68 (30.8%) of the IIM cases and 142 (21.5%) of the controls P=0.005). The likelihood of statin use in IIM patients was double the rate of what was observed in the control group. This resulted in an adjusted odds ratio, 1.79 (1.23-2.60; P = .001). When patients with necrotizing myositis were compared to controls an adjusted odds ratio of 1.92 (1.29-2.86; P = 0.001) was observed. Based on this analysis statin exposure significantly increased the risk of histologically established IIM. The wide spread use of statins warrants alertness and recognition of this rare adverse event associated with statin exposure.
