Atorvastatin rapidly reduce carotid plaque neovascularization
By using new imaging techniques to observe carotid plaque changes the authors examined the effects of atorvastatin on Chinese post ischemic stroke patients. From 117 patients that presented with an acute ischemic stroke in a single institution (June 2018 – February 2018), 86 were selected for further evaluation. Ultrasound imaging was performed and grayscale as well as superior microvascular imaging (SMI) and contrast enhance ultrasound sagittal images (CEUS) were acquired. Patients received 20 mg atorvastatin or placebo for 6 months and were evaluated at baseline and after 6 months. No significant differences could be discerned at baseline but after 6 months, patients treated with atorvastatin 20 mg showed marked reductions of total cholesterol, LDL-c and triglycerides. Both SMI and CEUS techniques revealed reduced intraplaque neovascularization’s 69.23% to 48.72% and 74.1% to 69.23% respectively. When Compared both techniques were markedly congruent: 0.75 (P<0.001). Patient allocated to the placebo group showed similar outcomes at baseline and after 6 months 65.12% to 67.44% for SMI and 74.41% to 74.41% for CEUS. The authors concluded that 6 months of atorvastatin 20 mg therapy reduced intraplaque neovascularization significantly and SMI performed on par with CEUS but is a safer and cheaper ultrasonographic technique that can be used to identify carotid plaque instability.

Updated meta-analysis on high dose statin pre-PCI
In this updated met-analysis of 15 randomized trials high dose statin pre-treatment improved final TIMI flow grade. In total 4240 patients were included in the selected 15 trials, 7 studies evaluated atorvastatin 80 mg, 7 trials rosuvastatin (3 using 20 mg and 4 using 40 mg) and 1 study was done with simvastatin 80 mg. High dose statin pre-PCI significantly improved final TIMI flow grade compared to the control group, OR 0.61 (0.46-0.80, p=0.0005)  After 1 month – 1 year of high dose statin treatment MACE were reduced by 48% When comparing high dose with moderate dose statins the incidence of MACE was reduced by 14.1% and 8.8% (p=0.018) respectively. No significant difference were observed in patients with stable angina. The authors pointed out that the timing of preloading was critical, in ACS patients, with a narrow therapeutic window of approximately 2 hrs. to reduce reperfusion injury and improving clinical outcomes. The authors concluded that high dose statin pre-PCI had a significant effect on post procedure myocardial perfusion, by improving TIMI flow, as well as reducing MACE, particularly in statin naïve and STEMI patents.

First Meta-analysis on anti-inflammatory properties of statins in MS
The two driving forces of atherosclerosis are lipids and inflammation. Statins address both, although the latter is still debated by some. In this meta-analysis statin anti-inflammatory effects in patients with metabolic syndrome (MS) were evaluated. MS patients are characterized by increased inflammatory markers in the plasma. The authors collected the published data of 113 RCT’s, that included 19 644 patients. The biomarkers studied in these trials and this meta-analysis were: hsCRP, TNF alpha, Il1 and IL6. Statin use in MS patients significantly reduce  hsCRP, SMD= -0.97 (-1.10, -0.85; P<0.001; I2: 95.1 %); TNFalpha SMD -1.88 (-2.40, -1.38; P<0.001; I2: 97.2 %); IL-6, SMD= -1.67 9 -1.98, -1.34; P<0.001; I2: 96.5 %); and IL-1 concentrations, SMD= -8.35 (-10.49, -6.22; P<0.001; I2: 98.4 %). The unequivocal anti-inflammatory effects of statins were confirmed in this meta-analysis, differences between statins and statin dosages could not be discerned from the collected data.

Rosuvastatin 40 mg improves plaque stability of non-culprit vessels in post-STEMI patients
In this observational study, 103 STEMI patients underwent an IVUS and OCT analysis on 2 of their non-infarct related arteries. The aim was to visualize the intrinsic vascular effects of statins by optical coherence tomography (OCT). Patients received rosuvastatin 20 for two weeks and continued with rosuvastatin 40 for the remaining study period of 13 months. Primary end points of the study were change in minimum fibrous cap thickness (FCT) and change in macrophage line arc. Secondary endpoints included change in mean FCT, lipid pool arc, and plaque type by OCT. Exploratory endpoints included macrophage dots. Serial OCT images were evaluable in 153 arteries of 83 patients. After study completion LDL-c was reduced from 128 mg/dl to 73.6 mg/dl. Minimum FCT (31 lesions/27 patients), increased from 64.9 ± 19.9 mm to 87.9 ± 38.1 mm (p = 0.008). Macrophage line arc decreased from 9.60 ± 12.80 to 6.460 ± 9.60 (p < 0.0001). The secondary endpoint, mean lipid arc, decreased from 55.90 ± 370 to 43.50 ± 33.50. In lesion-level analyses (n = 191), 9 of 13 thin-cap fibroatheromas (TCFAs) at baseline (69.2%) regressed to non-TCFA morphology, whereas 2 of 178 non-TCFA lesions (1.1%) progressed to TCFAs. The authors concluded that, within the limits of the observational nature of this study, 40 mg of Rosuvastatin was associated with markedly improved vascular OCT imaging characteristic of non-culprit vessels in post-STEMI patients. To confirm these observations, replication studies are warranted in order to re-assess if measuring OCT-defined coronary atheroma composition is clinically relevant and can be used as a follow-up evaluation to determine statin efficacy on promoting plaque stability.

Rosuvastatin for VTE prophylaxis?
In earlier statin trials, signals of reduced risk for venous thromboembolism (VTE) surfaced, but have never been fully explored. The risk for first VTE were 14-54% lower and recurrent VTE risk was reduced by 27% in patients that used statins. In this study patients with a history of VTE were included in a placebo controlled randomized 4-week trial. The aim was to establish if rosuvastatin 20 mg would prevent VTE events without increasing bleeding risk. Patients were asked to stop using anticoagulants 1 month prior to the start of the trials to observe relevant changes in their coagulation profile. Thrombin generation assay (TGA) was used to evaluate the anti-coagulant effects of statins. Because endogenous thrombin potential (ETP) and thrombin peak are validated markers for VTE risk, they were chosen as primary endpoints of this study. Of the 255 patients 245 completed the study; 126 were taking rosuvastatin and 119 were allocated to a placebo. An ETP increase of 7.8% was associated with placebo use and a 1.9% decrease in patients using rosuvastatin. The mean difference between treatments was calculated as 10.4% (4.5-16.2%). Thrombin peak increased in both treatment arms, but this was more pronounced in the placebo users, 7.6% vs 2.9% in the rosuvastatin group. Comparing the two treatment arms resulted in percentage thrombin peak difference of 5% (-0.2-10.2%). The observed changes associated with rosuvastatin were more pronounced in patients with CV risk factors and unprovoked VTE. This study corroborate earlier observations that statins affect coagulation and thrombin generation. The authors suggest that their finding provide the clinical rationale to conduct a large randomized controlled trial to evaluate the effectiveness of rosuvastatin to decrease risk of recurrent VTE complications.
