The Ideal

There is currently little data regarding the ideal management for a patient who has undergone recent percutaneous coronary intervention (PCI) and subsequently develops dengue fever. Patients with recent PCI are at high risk of stent thrombosis with cessation of dual anti-platelet therapy. On the other hand, patients with dengue viral infection are at high risk of bleeding. Managing patients with recent PCI and dengue involves the delicate balancing of the risk of thrombosis and bleeding. Careful consideration of the timing of coronary intervention and the severity of the dengue infection is required. We describe the management of the anti-thrombotic therapy in three different patients with dengue infection and recent PCI and discuss our approach to managing such patients.

The article presents an analytical review of the studies aimed at determining the optimal antithrombotic therapy in patients with atrial fibrillation undergoing elective or emergency percutaneous coronary intervention (PCI) due to the development of acute coronary syndrome (ACS). The results of the WOEST study are analysed. This study was the first to demonstrate an opportunity to safely discontinue administration of aspirin as part of the multicomponent antithrombotic therapy that included warfarin as an anticoagulant. Three studies were analysed - PIONEER AF-PCI, RE-DUAL-PCI and AUGUSTUS, where direct oral anticoagulants (DOACs) - rivaroxaban, dabigatran and apixaban were used as anticoagulants as part of the multicomponent therapy. The results of these studies formed the backbone of the updated European guidelines for the diagnosis and treatment of atrial fibrillation, 2020. The guidelines offer to divide patients with AF and ACS, who require multicomponent antithrombotic therapy, into two categories. The first group includes AF patients with uncomplicated PCI without a high risk of stent thrombosis, as well as patients with a risk of bleeding that prevails over the risk of stent thrombosis. The second category of patients, in contrast, is characterized by a high risk of stent thrombosis, which prevails over the risk of bleeding. In the absence of contraindications, the patients of both categories should choose DOAC as an anticoagulant and be prescribed clopidogrel as a P2Y12 inhibitor for 12 months. In AF patients with uncomplicated PCI without a high risk of stent thrombosis, as well as in patients with a risk of bleeding, which prevails over the risk of stent thrombosis, the period of treatment with the second antiplatelet drug (aspirin) should belimited to the hospital stay. Patients at increased risk of stent thrombosis and reduced risk of bleeding can extend the aspirin therapy for 1 month. The approaches to the choice of the duration and composition of the multicomponent antithrombotic therapy in AF patients taking oral anticoagulants after elective PCI are similar to those in ACS patients, except for the duration of clopidogrel therapy, which is reduced to 6 months in all patients.

Background: Bleeding is a common complication of percutaneous coronary intervention (PCI), leading to significant morbidity, mortality, and cost. While several risk models exist to predict post-PCI bleeding risk, however these existing models produce a single estimate of bleeding risk anchored at a single point in time. These models do not update the risk estimates as new clinical information emerges, despite the dynamic nature of risk. Objective: We sought to develop models that update estimates of patient risk of bleeding over time, enabling a dynamic estimate of risk that incorporates evolving clinical information, and to demonstrate updated predictive performance by incorporating this information. Methods: Using data available from the National Cardiovascular Data Registry (NCDR) CathPCI, we trained 6 different XGBoost tree-based machine learning models to estimate the risk of bleeding at key decision points: 1) choice of access site, 2) prescription of medication prior to PCI, and 3) the choice of closure device. Results: We included 2,868,808 PCIs; 2,314,446 (80.7%) prior to 2014 for training and 554,362 (19.3%) remaining for validation. Discrimination improved from an AUROC of 0.812 (95% Confidence Interval: 0.812-0.812) using only presentation variables to 0.845 (0.845-0.845) using all variables. Among 123,712 patients classified as low risk by the initial model, 14,441 were reclassified as moderate risk (1.4% experienced bleeds), while 723 patients were reclassified as high risk (12.5% experienced bleeds). Among 160,165 patients classified as high risk by the initial model, there were 40 patients reclassified to low risk (0% experienced bleeds), and 43,265 patients reclassified to moderate risk (2.5% experienced bleeds). Conclusion: Accounting for the time-varying nature of data and capturing the association between treatment decisions and changes in risk provide up-to-date information that may guide individualized care throughout a hospitalization.

A P2Y12 inhibitor-based monotherapy after a short period of dual antiplatelet therapy is emerging as a plausible strategy to decrease bleeding events in high-risk patients receiving dual antiplatelet therapy after percutaneous coronary intervention. Ticagrelor With Aspirin or Alone in High-Risk Patients After Coronary Intervention (TWILIGHT), a randomized double-blind trial, tested this approach by dropping aspirin at 3 months and continuing with ticagrelor monotherapy for an additional 12 months. The study enrolled 9,006 patients, of whom 7,119 who tolerated 3 months of dual antiplatelet therapy were randomized after 3 months into two arms: ticagrelor plus placebo and ticagrelor plus aspirin. The primary endpoint of interest, Bleeding Academic Research Consortium type 2, 3, or 5 bleeding, occurred less frequently in the experimental arm (HR 0.56; 95% CI [0.45–0.68]; p<0.001), whereas the secondary endpoint of ischemic events was similar between the two arms (HR 0.99; 95% CI [0.78–1.25]). Transition from dual antiplatelet therapy consisting of ticagrelor plus aspirin to ticagrelor-based monotherapy in high-risk patients at 3 months after percutaneous coronary intervention resulted in a lower risk of bleeding events without an increase in risk of death, MI, or stroke.
