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.
The HOPE-3 trial sought to determine if blood pressure (BP) and cholesterol-lowering therapies are effective and safe as primary prevention strategies in intermediate risk patients. The American College of Cardiology and American Heart Association (ACC/AHA) guidelines support a risk-based approach to statin use but in intermediate risk patients the tradeoffs between benefit and risk were deemed “less clear.” Do the results of HOPE-3 trial provide enough evidence to support routinely treating intermediate risk patients?
Two new mAbs, alirocumab and evolocumab, have been approved to treat elevated cholesterol when added to maximally tolerated statin therapy in patients with familial hypercholesterolemia or history of atherosclerotic cardiovascular disease (ASCVD). This new class of drugs, the proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, is considered to be the biggest breakthrough in cholesterol treatment since statins were approved 3 decades ago. But are they worth it?
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.
