Transcatheter aortic valve implantation (TAVI) carries a significant thromboembolic and concomitant bleeding risk, not only during the procedure but also during the periprocedural period. Many issues concerning optimal antithrombotic therapy after TAVI are still under debate. In the present review, we aimed to identify all relevant studies evaluating antithrombotic therapeutic strategies in relation to clinical outcomes after the procedure. Four randomized control trials (RCT) were identified analyzing the post-TAVI antithrombotic strategy with all of them utilizing aspirin lifelong plus clopidogrel for 3-6 months...

Small for gestational age is usually defined as an infant with a birthweight <10th centile for a population or customized standard. Fetal growth restriction refers to a fetus that has failed to reach its biological growth potential because of placental dysfunction. Small-for-gestational-age babies make up 28-45% of nonanomalous stillbirths, and have a higher chance of neurodevelopmental delay, childhood and adult obesity, and metabolic disease. The majority of small-for-gestational-age babies are not recognized before birth...

BACKGROUND: One-year dual antiplatelet therapy (DAPT), generally aspirin in combination with a P2Y12 receptor inhibitor, has been a standard treatment for patients undergoing percutaneous coronary intervention (PCI). Prolonged DAPT has proven itself effective in further reducing cardiovascular events, yet with increased risk of bleeding. Thus, it is of great necessity to find an alternative drug that is as effective but safer and more economic than the P2Y12 inhibitors after termination of one-year DAPT...

Background: Recurrent spontaneous abortion has high incidence rate. The etiology is unknown in 30-40%. However high uterine artery resistance is accounted as one of the recurrent abortion reasons. Objective: The objective of the current study was to determine the impacts of vitamin E and aspirin on the uterine artery blood flow in women having recurrent abortions due to impaired uterine blood flow. Materials and Methods: This randomized clinical trial was conducted on 99 women having uterine pulsatility index (PI) more than 2...

RATIONALE: Among atrial fibrillation patients with high risk of bleeding, left atrial appendage occlusion has emerged as an alternative to long-term oral anticoagulation therapy for stroke prevention. Device-related thrombus remains a major concern because it may result in recurrent embolic events. To date, there is no consensus on the optimal method of treating device-related-thrombus. PATIENT CONCERNS: A 78-year-old man with atrial fibrillation had an episode of intracranial hemorrhage while taking warfarin...

BACKGROUND: PFO is more common in cases with cryptogenic stroke compared to cases with no stroke or stroke of identified etiology. Several randomized controlled trials (RCTs) comparing PFO closure with medical therapy have been published with controversial findings. METHODS: PubMed, Embase and Cochrane library databases were searched for RCT comparing PFO closure with medical therapy including antiplatelet therapy (aspirin or clopidogrel or combination) or anticoagulation...

BACKGROUND: Bleeding is a well-known complication of percutaneous renal biopsy (PRB). Thus, antiplatelet agents are routinely held for most patients undergoing elective PRB to decrease bleeding risk. MATERIALS AND METHODS: In this systematic review, we examine the association between antiplatelet use and bleeding during PRB. MEDLINE and EMBASE were searched from inception to December 2016 using terms that included "renal biopsy", "antiplatelet","aspirin", and "bleeding"...

OBJECTIVE DATA: Impaired placentation in the first 16 weeks of pregnancy is associated with increased risk of subsequent development of preeclampsia, birth of small-for-gestational-age neonates, and placental abruption. Previous studies reported that prophylactic use of aspirin reduces the risk of preeclampsia and small-for-gestational-age neonates with no significant effect on placental abruption. However, meta-analyses of randomized controlled trials that examined the effect of aspirin in relation to gestational age at onset of therapy and dosage of the drug reported that significant reduction in the risk of preeclampsia and small-for-gestational-age neonates is achieved only if the onset of treatment is at ≤16 weeks of gestation and the daily dosage of the drug is ≥100 mg...

BACKGROUND: Orthopedic trauma patients are often treated with venous thromboembolism (VTE) chemoprophylaxis with aspirin or low molecular weight heparin (LMWH) after discharge from their index admission, but adherence patterns are not known. We hypothesized that overall adherence would be moderate and greater with aspirin compared to LMWH. METHODS: We conducted a randomized controlled trial of adult trauma patients with an operative extremity fracture or any pelvic/acetabular fracture requiring VTE prophylaxis...

Fetal growth restriction and related placental pathologies such as preeclampsia, stillbirth, and placental abruption are believed to arise in early pregnancy when inadequate remodeling of the maternal spiral arteries leads to persistent high-resistance and low-flow uteroplacental circulation. The consequent placental ischaemia, reperfusion injury, and oxidative stress are associated with an imbalance in angiogenic/antiangiogenic factors. Many interventions have centered on the prevention and/or treatment of preeclampsia with results pertaining to fetal growth restriction and small-for-gestational-age pregnancy often included as secondary outcomes because of the common pathophysiology...

BACKGROUND: Despite the fact that aspirin is of benefit to patients following coronary artery bypass grafting (CABG), continuation or administration of preoperative aspirin before CABG or any cardiac surgical procedure remains controversial. Therefore, we performed a systematic review and meta-analysis to assess the influence of preoperative aspirin administration on patients undergoing cardiac surgery. MATERIALS AND METHODS: Medline database was searched using OVID SP interface...

Clinicians struggle daily with the optimal regimen for patients with an indication for antiplatelet therapy after stenting and in patients needing oral anticoagulation treatment for atrial fibrillation (AF). This is not only difficult in patients with acute coronary syndrome (ACS) but also in the large number of patients with AF undergoing elective percutaneous coronary intervention (PCI). The challenge is to strike a balance between the increasing risk of bleeding events and ischemic or thrombotic events. Until recently, guidelines were based on expert consensus and a few small, many of them retrospective, trials...

Antiplatelet therapy is an attractive treatment option for critically ill patients. However, more evidence on the benefit of this therapy is required. We searched the PubMed and Embase databases from their inception to June 2017 for randomized controlled trials and observational studies that assess the effect of antiplatelet therapy in critically ill patients. Antiplatelet therapy resulted in significant decreases in hospital mortality (risk ratio [RR] 0.81, 95% confidence interval [CI], 0.68-0.97; P = 0...

OBJECTIVE DATA: Metaanalyses of randomized controlled trials have reported contradictory results about the effect of aspirin in the prevention of preeclampsia, both in terms of the gestational age at the onset of treatment and the dose of the drug. The controversy may be resolved by a metaanalysis that includes several recently published trials and particularly the large Combined Multimarker Screening and Randomized Patient Treatment with Aspirin for Evidence-based Preeclampsia Prevention trial and by examination of whether there is a difference of the effect of aspirin on preterm vs term preeclampsia...

Although aspirin monotherapy is considered the standard of care after coronary artery bypass grafting (CABG), more recent evidence has suggested a benefit with dual antiplatelet therapy (DAPT) after CABG. We performed a meta-analysis of observational studies and randomized controlled trials comparing outcomes of aspirin monotherapy with DAPT in patients after CABG. Subgroup analyses were conducted according to surgical technique (i.e., on vs off pump) and clinical presentation (acute coronary syndrome vs no acute coronary syndrome)...

PURPOSE OF REVIEW: Ischemic stroke during pregnancy or the puerperium is a devastating disease during a crucial period in life and warrants a specific approach. To date, current practice is mainly based on expert opinion because of a lack of randomized controlled trials and high-quality observational studies. The present review is intended as a practical guide to (acute) management of ischemic stroke during pregnancy and puerperium. RECENT FINDINGS: Recent findings showed that the incidence of stroke during pregnancy is rising...
