For the acute treatment of venous thromboembolism, the direct oral anticoagulants (DOACs) have increasingly replaced injectable anticoagulant therapy followed by warfarin. For patients with an unprovoked deep vein thrombosis or pulmonary embolism who may benefit from long-term extended prophylaxis for the secondary prevention of VTE, the choice is less clear. Should a DOAC be used? If so, which one and what's the best dose? What about low-dose aspirin? Is extended therapy needed at all? The EINSTEIN CHOICE study adds important new insights to the growing body of literature.
More than 15 million Americans have coronary heart disease and most should be taking aspirin daily. Given aspirin’s ubiquity in cardiovascular medicine and patients’ pill boxes, it is shocking that there are still so many unanswered questions about aspirin use. Which dose and dosage forms should be prescribed? How common is aspirin resistance? What is the relationship between platelet inhibition and clinical outcomes?
Many patients with atrial fibrillation (AF) received triple antithrombotic therapy after undergoing a percutaneous coronary intervention (PCI) and receiving cardiac stent. Triple therapy consists of warfarin plus dual antiplatelet therapy (DAPT) with a P2Y12 inhibitor and low-dose aspirin. But is triple therapy the best approach? This practice, while widely employed, is not entirely evidence-based. Moreover, the effectiveness and safety of the direct oral anticoagulants (DOACs) in this patient population is unknown.
Several studies have evaluated the correlation between low-dose aspirin and NSAID use and the development of colorectal cancer. In 2007, the U.S. Preventive Services Task Force (USPSTF) recommended against the use aspirin for the prevention of colorectal cancer in most adults. However, there is mounting evidence that daily, long-term aspirin use may prevent colorectal cancer in patients aged 50-69. Could something as simple as an aspirin a day prevent colon CA?
The CHANCE (Clopidogrel in High risk patients with Acute Non-disabling Cerebrovascular Events) trial investigators examine whether patients who have a TIA or mini-stroke should receive aspirin AND clopidogrel to reduce the risk of recurrent stroke.
Our guests - Dr. Cortney Mospan and Dr. Augustus (Rob) Hough - critically examine the results of the DAPT and PEGASUS-TIMI 54 studies and explain how the results should be applied in practice.
