BACKGROUND: The beneficial prognostic impact of statins has been established in patients with ischemic heart disease but not in those with heart failure (HF). In addition, it is still unclear whether patients benefit from statins regardless of low-density lipoprotein cholesterol levels. METHODS AND RESULTS: We examined 2444 consecutive stage C or D HF patients with ischemic heart disease registered in CHART-2 (Chronic Heart Failure Registry and Analysis in the Tohoku District 2), a multicenter, prospective, observational cohort study in Japan...

INTRODUCTION: Obesity might negatively affect prostate cancer (PCa) outcomes. However, evidence according to the associations between obesity and metastases-free survival after radical prostatectomy (RP) is still inconsistent. METHODS: We relied on PCa patients treated with RP at the Martini-Klinik Prostate Cancer Center between 2004 and 2015. First, multivariable Cox regression analyses examined the impact of obesity on metastases after RP. Last, in a propensity score matched cohort, Kaplan-Meier analyses assessed metastases-free survival according to body mass index (kg/m2 ) (BMI) strata (≥ 30 vs...

PURPOSE: Only small and short-term studies have evaluated statins in relation to changes in heart structure. We estimated the association between new statin use and 10-year remodeling of the left ventricle. METHODS: The Multi-Ethnic Study of Atherosclerosis collected data on statin use over approximately 10 years, conducting cardiac magnetic resonance (CMR) imaging at baseline and the 10-year exam. Participants were free of baseline cardiovascular disease, and we excluded users of statins at baseline...

One important goal in pharmaco-epidemiology studies is to understand the causal relationship between drug exposures and their clinical outcomes, including adverse drug events. In order to achieve this goal, however, we need to resolve several challenges. Most of pharmaco-epidemiology data are observational and confounding is largely present due to many co-medications. The pharmaco-epidemiology study data set is often sampled from large medical record databases using a matched case-control design, and it may not be representative of the original patient population in the medical record databases...

BACKGROUND: Statins can exert pleiotropic anti-inflammatory, vascular protective and anticoagulant effects, which in theory could improve the dysregulated host response during sepsis. We aimed to determine the association between prior statin use and host response characteristics in critically ill patients with sepsis. METHODS: We performed a prospective observational study in 1060 patients admitted with sepsis to the mixed intensive care units (ICUs) of two hospitals in the Netherlands between January 2011 and July 2013...

PURPOSE: The effectiveness of statins in improving clinical outcomes among patients with heart failure (HF) undergoing percutaneous coronary intervention (PCI) is unclear. We examined the association between use of statins and clinical outcomes in patients with HF included in the Melbourne Interventional Group registry. METHODS: Patients were followed from 30 days to 1 year post-PCI for a primary composite outcome of all-cause mortality and hospitalisation for cardiovascular (CV) causes...

BACKGROUND: The rate of cardiovascular implantable electronic device infection (CIEDI) has increased, despite the use of perioperative antibiotics at the time of device placement or revision. This is due, in part, to the presence of multiple comorbid conditions in an elderly population, in general, who require CIED. Statins may have an antibacterial effect, although there is currently no evidence that the likelihood of CIEDI has been impacted by statin use. METHODS: A retrospective cohort study was performed to assess whether statins are associated with a reduced risk of CIEDI...

Background -Statin dose guidelines for Peripheral Artery Disease (PAD) patients are largely based on coronary artery disease and stroke data. The aim of this study is to determine the effect of statin intensity on PAD outcomes of amputation and mortality. Methods -Using an observational cohort study design and a validated algorithm we identified incident PAD patients (2003-2014) in the national Veterans Affairs data. Highest statin intensity exposure [high intensity vs low- moderate intensity vs antiplatelet therapy but no statin use (AP only)] was determined within one year of diagnosis of PAD...

BACKGROUND: Although ß-blockers are known to increase new-onset diabetes mellitus (DM), previous evidence have been controversial. It has been suggested that newer vasodilatory ß-blockers yield better glycemic control than older nonselective agents. The aim of this study was to evaluate the diabetogenicity of currently used newer ß-blockers based on ß1 receptor selectivity in a series of Asian population. METHODS: We investigated a total of 65,686 hypertensive patients without DM from 2004 to 2014...

BACKGROUND: Although statins deteriorate glucose metabolism, their glucose-lowering effects have emerged in some situations. Here, we assessed whether these effects are a consequence of statins' interaction with paraoxonase (PON)1 enzyme polymorphism. METHODS: Adult Japanese type 2 diabetes patients (n = 3798) were enrolled in a cross-sectional study. We used Q192R polymorphism of the PON1 gene as a representative single-nucleotide polymorphism and focused on the effects of the wild-type Q allele, in an additive manner...

BACKGROUND: The aim of this study is to investigate whether statin therapy can reduce new-onset acute coronary syndrome (ACS) in patients with rheumatoid arthritis (RA). METHODS: We used a database from the Registry for Catastrophic Illness from the National Health Research Institute (NHRI) in Taiwan. All RA patients aged 18 or older, diagnosed between 1995 and 2013, without previous cardiovascular events were included. We divided participants into quartiles according to the accumulated statin equivalent dosage and tertiles of period of days of statin treatment to examine the possible dose-response effect...

The use of retrospective healthcare claims datasets is frequently criticized for the lack of complete information on potential confounders. Utilizing patient's health status-related information from claims datasets as surrogates or proxies for mismeasured and unobserved confounders, the high-dimensional propensity score algorithm enables us to reduce bias. Using a previously published cohort study of post-myocardial infarction statin use (1998 - 2012), we compare the performance of the algorithm with a number of popular machine learning approaches for confounder selection in high-dimensional covariate spaces: random forest, least absolute shrinkage and selection operator, and elastic net...

Lung transplant recipients (LRs) have a reduced median 5-year survival of approximately 55% primarily due to chronic lung allograft dysfunction (CLAD). Statins have anti-inflammatory and immunomodulatory effects that may facilitate CLAD prevention. This study sought to evaluate statin effect on CLAD development. Adult bilateral LRs from January 2004 to October 2013 were included. Statin group included recipients with early statin use and continued for minimum 6 months. Propensity score matching was performed for age, gender, and native lung disease to select matched nonstatin group...
