PURPOSE: Few studies have evaluated the chemopreventive effect of aspirin on the cancer risk in elderly women. We examined associations between frequency, dose, and duration of aspirin use with incidence of 719 aspirin-sensitive cancers (cancers of colon, pancreas, breast, and ovaries) in the Iowa Women's Health Study (IWHS), a prospective cohort of women over 70 years old. METHODS: Aspirin frequency, dose, and duration were self-reported in the 2004 IWHS questionnaire...

BACKGROUND: Preeclampsia (PE) and fetal growth restriction (FGR) are major causes of perinatal death and handicap in survivors. Randomized clinical trials (RCTs) have reported that the risk of PE, severe PE and FGR can be reduced by the prophylactic use of aspirin in high-risk women, but the appropriate dose of the drug to achieve this objective is not certain. OBJECTIVE: To estimate the impact of aspirin dosage on the prevention of PE, severe PE and FGR. STUDY DESIGN: We performed a systematic review and meta-analysis of RCTs comparing the effect of daily aspirin or placebo (or no treatment) during pregnancy...

BACKGROUND: Resistance to anti-platelet therapy is detrimental to patients. Our aim was to establish a predictive model for aspirin resistance to identify high-risk patients and to propose appropriate intervention. METHODS: Elderly patients (n = 1130) with stable chronic coronary heart disease who were taking aspirin (75 mg) for > 2 months were included. Details of their basic characteristics, laboratory test results, and medications were collected. Logistic regression analysis was performed to establish a predictive model for aspirin resistance...

BACKGROUND: In the PEGASUS-TIMI 54 trial (Prevention of Cardiovascular Events in Patients With Prior Heart Attack Using Ticagrelor Compared to Placebo on a Background of Aspirin-Thrombolysis in Myocardial Infarction 54), ticagrelor reduced the risk of major adverse cardiovascular events when added to low-dose aspirin in stable patients with prior myocardial infarction, resulting in the approval of ticagrelor 60 mg twice daily for long-term secondary prevention. We investigated the incidence of stroke, outcomes after stroke, and the efficacy of ticagrelor focusing on the approved 60 mg twice daily dose for reducing stroke in this population...

Dual antiplatelet therapy (DAPT) with clopidogrel and aspirin is a widely prescribed regimen to prevent ischemic events in patients undergoing percutaneous coronary intervention (PCI). A fixed-dose combination (FDC) capsule (HCP0911) has been developed to provide dosing convenience and improve adherence. We compared the antiplatelet effects of single daily dose HCP0911 with separate treatment with daily 75 mg clopidogrel plus 100 mg aspirin. This was a randomized, open-label, two-period, crossover, non-inferiority study conducted in stented patients who had been treated for at least 6 months with clopidogrel and aspirin...

AIMS: Clinical utilization of dual antiplatelet therapy (DAPT) in patients with renal impairment (RI) following percutaneous coronary interventions (PCI) represents an urgent, unmet need choosing optimal agents, duration of treatment, and potential dose/regimen adjustment. The lack of any large randomized trials specifically in RI patients, and the absence of the uniformed clinical data reporting policy, clouds the reality. Moreover, triaging RI patients is problematic due to ongoing kidney deterioration, and the fact that RI patients are prone to both vascular occlusions and bleeding...

BACKGROUND: Low-dose aspirin has proven effectiveness in secondary and primary prevention of cardiovascular events, but is also associated with an increased risk of major bleeding events. For primary prevention, this absolute risk must be carefully weighed against the benefits of aspirin; such assessments are currently limited by a lack of data from general populations. METHODS: Systematic searches of Medline and Embase were conducted to identify observational studies published between 1946 and 4 March 2015 that reported the risks of gastrointestinal (GI) bleeding or intracranial hemorrhage (ICH) with long-term, low-dose aspirin (75-325 mg/day)...

Patients with ischemic heart disease are administered a dual antiplatelet therapy after percutaneous coronary intervention. This consists of aspirin and thienopyridine, which can be switched from prasugrel to clopidogrel. However, the impact of switching is unknown. This study aimed to determine the efficacy and safety of switching from prasugrel to clopidogrel in Japanese patients. One-hundred and thirty-six patients with acute coronary syndrome scheduled to undergo percutaneous coronary intervention and patients with coronary artery disease requiring elective coronary stenting were enrolled...

Several platelet function tests (PFT) are available to assess the pharmacodynamic (PD) effects of P2Y12 inhibitors. However, there are technical variances between PFT, and P2Y12 inhibitors differ in pharmacological properties. Manufactures of PFT recommend a time-frame within which assessments needs to be executed. However, if the timing from blood sampling to processing affects PD results is unknown. We conducted a prospective study assessing the impact of timing from blood sampling to processing on PD measures using three different PFT...

Associations between atrial fibrillation (AF), outcomes, and response to antiplatelet therapies in patients with acute coronary syndrome (ACS) managed medically without revascularization remain uncertain. We examined these associations for medically managed ACS patients randomized to dual antiplatelet therapy (DAPT) using patient data from the TRILOGY ACS trial. DAPT included aspirin plus clopidogrel 75 mg/d or prasugrel 10 mg/d (5 mg/d for those <60 kg or age ≥75 years). Patients receiving oral anticoagulants were excluded...

BACKGROUND AND PURPOSE: In patients with acute ischemic stroke caused by large artery atherosclerosis, clopidogrel plus aspirin versus aspirin alone might be more effective to prevent recurrent cerebral ischemia. However, there is no clear evidence. METHODS: In this multicenter, double-blind, placebo-controlled trial, we randomized 358 patients with acute ischemic stroke of presumed large artery atherosclerosis origin within 48 hours of onset to clopidogrel (75 mg/d without loading dose) plus aspirin (300-mg loading followed by 100 mg/d) or to aspirin alone (300-mg loading followed by 100 mg/d) for 30 days...
