BACKGROUND: Aspirin increases the risk of gastrointestinal bleeding. AIM: To investigate the risk of lower gastrointestinal bleeding (LGIB) in aspirin users. METHODS: Low-dose (75-325 mg daily) aspirin users and controls matched by age, gender and enrollment time in a 1:5 ratio were selected from 1 million randomly sampled subjects in the National Health Insurance Research Database of Taiwan. Cox proportional hazard regression models were developed to evaluate the predictors of LGIB with adjustments for age, gender, comorbidities including coronary artery disease, ischaemic stroke, diabetes, hypertension, chronic kidney disease, liver cirrhosis, chronic obstructive pulmonary disease, dyslipidemia, uncomplicated peptic ulcer disease, history of peptic ulcer bleeding, and concomitant use of clopidogrel, ticlopidine, warfarin, nonsteroidal anti-inflammatory drugs (NSAIDs), cyclooxygenase-2 inhibitors, steroids, proton pump inhibitors (PPIs), histamine-2 receptor antagonists (H2RAs), nitrates, alendronate, selective serotonin reuptake inhibitors (SSRIs) and calcium channel blockers...

BACKGROUND AND PURPOSE: Cardioembolic stroke accounts for approximately 15%-20% of all ischemic strokes. Atrial fibrillation constitutes one-half to two-thirds of all cardioembolic stroke events. The association of paroxysmal supraventricular tachycardia (PSVT) with ischemic stroke remains unclear. A national case-control study was conducted to identify the risk factors, including PSVT, for ischemic stroke in Taiwan. METHODS: We designed a national case-control study comprising patients diagnosed with ischemic stroke (n = 5633) from 1997 to 2011; each patient from the case group was randomly matched with the control group (n = 30,895) in Taiwan...

Background: There are no primary prevention trials of aspirin with relevant geriatric outcomes in elderly people. ASPirin in Reducing Events in the Elderly (ASPREE) is a placebo-controlled trial of low-dose aspirin that will determine whether 5 years of daily 100-mg enteric-coated aspirin extends disability-free and dementia-free life in a healthy elderly population and whether these benefits outweigh the risks. Methods: Set in primary care, this randomized double-blind placebo-controlled trial has a composite primary endpoint of death, incident dementia or persistent physical disability...

Antiplatelet therapy reduces the risk of myocardial infarction, stroke, and vascular death in patients who have symptomatic peripheral artery disease. However, a subset of patients who take aspirin continues to have recurrent cardiovascular events. There are few data on cardiovascular outcomes in patients with peripheral artery disease who manifest aspirin resistance. Patients with peripheral artery disease on long-term aspirin therapy (≥4 wk) were tested for aspirin responsiveness by means of the VerifyNow Aspirin Assay...

REVIEW
Aparna Dalal
Patients listed for organ transplant frequently have severe coronary artery disease (CAD), which may be treated with drug eluting stents (DES). Everolimus and zotarolimus eluting stents are commonly used. Newer generation biolimus and novolimus eluting biodegradable stents are becoming increasingly popular. Patients undergoing transplant surgery soon after the placement of DES are at increased risk of stent thrombosis (ST) in the perioperative period. Dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 inhibitor such as clopidogrel, prasugrel and ticagrelor is instated post stenting to decrease the incident of ST...

Importance: Vascular access dysfunction is a leading cause of morbidity and mortality in patients requiring hemodialysis. Arteriovenous fistulae are preferred over synthetic grafts and central venous catheters due to superior long-term outcomes and lower health care costs, but increasing their use is limited by early thrombosis and maturation failure. ω-3 Polyunsaturated fatty acids (fish oils) have pleiotropic effects on vascular biology and inflammation and aspirin impairs platelet aggregation, which may reduce access failure...

BACKGROUND: Previous studies of contrast-induced acute kidney injury (CI-AKI) were mostly based on selective percutaneous coronary intervention (PCI) cases, and risk factors of CI-AKI after emergency PCI are unclear. The aim of this study was to explore the risk factors of CI-AKI in a Chinese population undergoing emergency PCI. METHODS: A total of 1061 consecutive patients undergoing emergency PCI during January 2013 and June 2015 were enrolled and divided into CI-AKI and non-CI-AKI group...

BACKGROUND: Aspirin use is effective in the prevention of cardiovascular disease; however, not all patients are equally responsive to aspirin. Oxidative stress reflected by F2-isoprostane [8-iso-prostaglandin-F2α (8-IsoPGF2α)] is a potential mechanism of failure of aspirin to adequately inhibit cyclooxygenase-1. The objective was to examine the relation between all-cause mortality and the concentrations of urinary 11-dehydro thromboxane B2 (11dhTxB2) and 8-IsoPGF2α in patients with stable coronary artery disease (CAD)...

OBJECTIVES: Despite improvements in immunosuppressive protocols for renal transplant, long-term success of renal transplant is still limited by the occurrence of interstitial fibrosis and tubular atrophy. Some studies have shown that aspirin decreases the severity of kidney ischemia-reperfusion injury and the development of tubular atrophy in animal models. This study aimed to assess the effects of aspirin therapy started at the time of transplant on long-term graft function. MATERIALS AND METHODS: We compared renal graft function of 82 patients on low-dose aspirin 75 mg once daily who underwent renal transplant between 1 January 2000 and 31 December 2010 from a single center with 65 patients not taking aspirin...

The efficacy of antiplatelet therapy for the secondary prevention of cardiovascular disease after an ischemic event is well established. However, the role for antiplatelet therapy for the primary prevention of cardiovascular disease is more complex because of the interplay of efficacy vs safety in individuals without established cardiovascular disease who have a relatively low, but linear trajectory of cardiovascular risk. Several large randomized trials have investigated the efficacy and safety of antiplatelet therapy (primarily aspirin) for patients without established cardiovascular disease...

The consumption of low-dose aspirin (LDA) to prevent cardiovascular disease continues to increase worldwide. Consequently, the number of chronic LDA users seeking dental procedures that require complementary acute anti-inflammatory medication has also grown. Considering the lack of literature evaluating this interaction, we analyzed the gastric and renal effects caused by a selective COX-2 inhibitor (etoricoxib) and a non-selective COX-2 inhibitor (ibuprofen) nonsteroidal anti-inflammatory drug (NSAID) in rats receiving chronic LDA therapy...

REVIEW
Julian Yaxley
An association between non-opioid analgesic agents and chronic kidney disease has long been suspected. The presumed development of chronic renal impairment following protracted and excessive use of non-opioid analgesia is known as analgesic nephropathy. Many clinicians accept analgesic nephropathy as a real entity despite the paucity of scientific evidence. This narrative review aims to summarize the literature in the field. The weight of available observational literature suggests that long-term ingestion of paracetamol and combination mixtures of aspirin and paracetamol are likely to contribute to chronic renal impairment...

High on-aspirin platelet reactivity (HAPR) has been associated with compromised aspirin efficacy in patients with diabetes suffering from acute cardiovascular events, but the key mechanisms remain elusive. The objective of this study was to uncover the potential link between pathogenic accumulation of salicylic acid (SA), the major metabolite of aspirin, and HAPR in diabetic state. Aspirin failed to inhibit platelet CD62P expression and thromboxane (TX) B2/6-keto-prostaglandin(PG)F1α ratio in a type 2 diabetes mellitus (T2DM) mice model, particularly in the female, which were unanimously accompanied by significantly higher plasma SA concentrations...
