TL;DR: In this paper, the authors showed that 80 mg of atorvastatin per day reduced the overall incidence of stroke and cardiovascular events, despite a small increase in the incidence of hemorrhagic stroke.

Abstract: Background Statins reduce the incidence of strokes among patients at increased risk for cardiovascular disease; whether they reduce the risk of stroke after a recent stroke or transient ischemic attack (TIA) remains to be established. Methods We randomly assigned 4731 patients who had had a stroke or TIA within one to six months before study entry, had low-density lipoprotein (LDL) cholesterol levels of 100 to 190 mg per deciliter (2.6 to 4.9 mmol per liter), and had no known coronary heart disease to double-blind treatment with 80 mg of atorvastatin per day or placebo. The primary end point was a first nonfatal or fatal stroke. Results The mean LDL cholesterol level during the trial was 73 mg per deciliter (1.9 mmol per liter) among patients receiving atorvastatin and 129 mg per deciliter (3.3 mmol per liter) among patients receiving placebo. During a median follow-up of 4.9 years, 265 patients (11.2 percent) receiving atorvastatin and 311 patients (13.1 percent) receiving placebo had a fatal or nonfatal stroke (5-year absolute reduction in risk, 2.2 percent; adjusted hazard ratio, 0.84; 95 percent confidence interval, 0.71 to 0.99; P=0.03; unadjusted P=0.05). The atorvastatin group had 218 ischemic strokes and 55 hemorrhagic strokes, whereas the placebo group had 274 ischemic strokes and 33 hemorrhagic strokes. The five-year absolute reduction in the risk of major cardiovascular events was 3.5 percent (hazard ratio, 0.80; 95 percent confidence interval, 0.69 to 0.92; P=0.002). The overall mortality rate was similar, with 216 deaths in the atorvastatin group and 211 deaths in the placebo group (P=0.98), as were the rates of serious adverse events. Elevated liver enzyme values were more common in patients taking atorvastatin. Conclusions In patients with recent stroke or TIA and without known coronary heart disease, 80 mg of atorvastatin per day reduced the overall incidence of strokes and of cardiovascular events, despite a small increase in the incidence of hemorrhagic stroke.

Association Between Intensity of Low-Density Lipoprotein Cholesterol Reduction With Statin-Based Therapies and Secondary Stroke Prevention
TL;DR: It is suggested that more intensive LDL-C–lowering statin-based therapies might be warranted for patients with ischemic stroke with evidence of atherosclerosis.
Non-high-density lipoprotein cholesterol: current status as cardiovascular marker.
TL;DR: The existing evidence supports the claim that non-HDL-C is superior to LDL-C in CVD risk estimation, and there are no recent findings, which are deemed to cause a change of the current opinion about non- HDL-C as a predictor for CVD.

Atorvastatin : Pharmacological Characteristics and Lipid-Lowering Effects
TL;DR: Atorvastatin can be considered one of the most effective statins, not only by taking into account its effects on LDL-C and ability to meet recommended treatment guidelines for this parameter, but also its effect on triglyceride levels and capacity to modify lipoprotein composition in a non-atherogenic manner.

Blood pressure and total cholesterol level are critical risks especially for hemorrhagic stroke in Akita, Japan.
TL;DR: Serum total cholesterol <160 mg/dl was a risk factor for hemorrhagic stroke (CH and SAH), whereas TC >280mg/dl increased the risk of CI, and a multivariable analysis revealed that the lower TC level and the higher BP increased the relative risk of hemorrhagic Stroke.

Management of intracerebral hemorrhage
TL;DR: This review focuses on comprehensive management of ICH in light of recent evidence, and includes prompt evaluation of the patient at a facility with stroke and neurosurgical expertise, and consideration of early surgery for patients with clinical deterioration or cerebellar hemorrhages larger than 3 cm.

TL;DR: Pravastatin therapy reduced mortality from coronary heart disease and overall mortality, as compared with the rates in the placebo group, as well as the incidence of all prespecified cardiovascular events in patients with a history of myocardial infarction or unstable angina who had a broad range of initial cholesterol levels.

TL;DR: The reductions in major cardiovascular events with atorvastatin are large, given the short follow-up time, and may have implications for future lipid-lowering guidelines.
