BACKGROUND: The benefit of statin on the management of Type 2 Diabetes Mellitus (T2DM) among Chinese patients in primary care is not clear nor fully implemented in clinical practice. This study aimed to evaluate and quantify the benefit of statin on the overall cardiovascular risk and all-cause mortality in patients with T2DM. METHODS: Uncomplicated diabetic patients with baseline low-density-lipoprotein cholesterol (LDL-C) > 2.6 mmol/L and without statin use before baseline in 2010 were followed-up for 5 years for cardiovascular disease (CVD) events and all-cause mortality...

BACKGROUND: Published evidence indicates that individual use of metformin and statin is associated with reduced cancer mortality. However, their differential and joint effects on pancreatic cancer survival are inconclusive. METHODS: We identified a large population-based cohort of 12,572 patients aged 65 years or older with primary pancreatic ductal adenocarcinoma (PDAC) diagnosed between 2008 and 2011 from the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked database...

BACKGROUND: Exercise and statins reduce cardiovascular disease (CVD). Exercise capacity may be assessed using cardiopulmonary exercise testing (CPET). Whether statin medication is associated with CPET parameters is unclear. We investigated if statins are related with exercise capacity during CPET in the general population. METHODS: Cross-sectional data of two independent cohorts of the Study of Health in Pomerania (SHIP) were merged (n = 3,500; 50% males). Oxygen consumption (VO2) at peak exercise (VO2peak) and anaerobic threshold (VO2@AT) was assessed during symptom-limited CPET...

An important side effect of diagnostic contrast drugs is contrast-induced acute kidney injury (CI-AKI; a sudden decrease in renal function) occurring 48-72 hours after injection of a contrast drug that cannot be attributed to other causes. Its existence has recently been challenged, because of some retrospective studies in which the incidence of AKI was not different between subjects who received a contrast drug and those who did not, even using propensity score matching to prevent selection bias. For some authors, only patients with estimated glomerular filtration rate <30 mL/min/1...

BACKGROUND: Primary graft dysfunction (PGD) is a major cause of early morbidity and mortality after lung transplantation. Statins reduce the risk of chronic rejection after lung transplantation, but their effects on PGD are unknown. We hypothesized that perioperative statin therapy decreases the risk for PGD after lung transplantation. METHODS: We retrospectively reviewed records of all patients undergoing lung transplantation between January 1999 and December 2014 at the University of Virginia Health System...

An abdominal aortic aneurysm (AAA) is an enlargement of the abdominal aorta. It is a common disease in the elderly, with a prevalence of 1-5%. An AAA is normally asymptomatic, and the diagnosis is often incidental, identified when a patient is examined for other conditions. The major risk of having an AAA is sudden rupture and death caused by massive hemorrhaging. As rupture risk increases with increasing AAA diameter, the current management strategies include regular imaging surveillance and elective repair before rupture occurs...

OBJECTIVE: The 2013 American College of Cardiology/American Heart Association lipid management guidelines recommend high-intensity statins for all patients ≤75 years old with chronic limb-threatening ischemia (CLTI) and moderate-intensity statins for CLTI patients >75 years old without contraindications or on dialysis, but these recommendations are based primarily on coronary and stroke data. We aimed to validate these guidelines in patients with CLTI and to assess current adherence to these recommendations...

BACKGROUND: Autosomal dominant polycystic kidney disease (ADPKD) commonly results in end-stage renal disease (ESRD), yet a long-term treatment that is well tolerated is still lacking. In a small randomized trial in children and adolescents pravastatin administration for 3 years was associated with reduced renal cyst growth, but no large trial has tested the effect of statins in adults. METHODS: We performed a post-hoc analysis of the HALT PKD trials to compare outcomes of participants who never used statins with those who used statin for at least 3 years...

Several studies have reported constipation, abdominal pain, or diarrhea as common adverse events for statins. Statins are among the most commonly prescribed medications, and the impact on the prevalence of these conditions was rarely studied as main outcomes. The aim of this study is to determine if statin therapy is associated with constipation, abdominal pain, diarrhea, or colitis. This was a retrospective cohort study using a regional military health care data from October 1, 2003, to March 1, 2012. A propensity score-matched cohort of statin users and nonusers was created based on 82 variables...

BACKGROUND: A fixed baseline period has been a common covariate assessment approach in pharmacoepidemiological studies from claims but may lead to high levels of covariate misclassification. Simulation studies have recommended expanding the look-back approach to all available data (AAD) for binary indicators of diagnoses, procedures, and medications, but there have been few real data analyses using this approach. OBJECTIVE: The objective of the study is to explore the impact on treatment effect estimates and covariate prevalence of expanding the look-back period within five validated studies in the Aetion system, a rapid cycle analytics platform...

BACKGROUND: Attempts to predict who is at risk of future nonadherence have largely focused on predictions at the time of therapy initiation; however, these users are only a small proportion of all patients on therapy at any point in time. Methods to predict nonadherence for established medication users, which have not been previously described in the literature, would be helpful to guide efforts to enhance the use of evidence-based therapies. OBJECTIVE: To test approaches for adherence prediction among prevalent statin users, namely the use of short-term filling behavior, investigator-specified predictors from medical and pharmacy administrative claims, and the empirical selection of potential predictors using the high-dimensional propensity score variable selection algorithm...

BACKGROUND: In patients with chronic heart failure (CHF) increasing levels of total serum cholesterol are associated with improved survival - while statin usage is not. The impact of statin treatment on the "reverse epidemiology" of cholesterol is unclear. METHODS: 2992 consecutive patients with non-ischemic CHF due to left ventricular systolic dysfunction from the Norwegian CHF Registry and the CHF Registries of the Universities of Hull, UK, and Heidelberg, Germany, were studied...

BACKGROUND & AIM: Statin decreased the risk of decompensation and mortality in veteran patients with cirrhosis due to hepatitis C virus (HCV). Whether this beneficial effect can be extended to cirrhosis in general population or cirrhosis with other causes, such as hepatitis B virus (HBV) infection and alcohol, remains unknown. Statin also decreased the risk of hepatocellular carcinoma (HCC) in patients with chronic HBV and HCV infection. It is unclear whether the effect can be observed in patients already with cirrhosis...

Inflammation is an increasingly recognized hallmark of pulmonary hypertension (PH). Statins have been shown to attenuate key pathologic mechanisms via pleiotropic effects in animal models. However, clinical benefit of statins in patients with PH is unknown and their effect on mortality has not been studied. We performed a retrospective analysis of patients between January 2002 to January 2012, with severe PH (pulmonary artery systolic pressure ≥60 mmHg) and preserved left ventricular function (ejection fraction ≥50%), defined by transthoracic echocardiograms...

BACKGROUND: The clinical benefits of a combination of statins and ezetimibe in patients with acute coronary syndrome (ACS) were observed in a clinical trial. However, little is known regarding the effectiveness of using statins with or without ezetimibe in patients with ACS and multiple comorbidities in real-world clinical practice. METHODS: This is a nationwide population-based cohort study using Taiwan National Health Insurance Research Database. A total of 212,110 patients with ACS who had been discharged after their first ACS events between 2006 and 2010 were enrolled...
