Dyspnea and reversibility of antiplatelet agents: ticagrelor, elinogrel, cangrelor, and beyond.
Oral reversible platelet P2Y12 receptor inhibitors (ticagrelor and elinogrel) cause double-digit rates of dyspnea, while irreversible oral antiplatelet drugs (aspirin, ticlopidoine, clopidogrel, and prasugrel) or intravenous glycoprotein IIb/IIIa inhibitors (abciximab, eptifibatide, or tirofiban) do not increase the incidence of dyspnea in randomized trials. Dyspnea after oral reversible antiplatelet agents remains unexplained. A transfusion-related acute lung injury (TRALI) hypothesis has been proposed. The dyspnea risks after cangrelor, an intravenous reversible antiplatelet agent, are not well defined but may offer a universal mechanism linking TRALI, dyspnea, and reversible platelet inhibition.. We analyzed safety data from recent head-to-head randomized trials with reversible antiplatelet agents (ticagrelor, elinogrel, and cangrelor) compared to irreversible (clopidogrel/placebo) comparators.. All three reversible antiplatelet agents cause excess dyspnea. In contrast to the high double-digit rates after oral ticagrelor or elinogrel, the dyspnea risks after intravenous cangrelor were smaller (<2%) but still consistently and significantly higher than in the corresponding control arms.. The clinical utility of reversible antiplatelet strategies has been challenged. Despite a potential advantage of fewer bleeding events during heart surgery, reversible antiplatelet agents carry the risk of potential autoimmune reactions manifesting as dyspnea. Repeated binding and unbinding cycles, impaired platelet turnover, and lung sequestration or apoptosis of overloaded destructive platelets are among the potential mechanism(s) responsible for dyspnea after reversible antiplatelet agents.

Dyspnea and reversibility profile of P2Y₁₂ antagonists: systematic review of new antiplatelet drugs.
Dyspnea has been consecutively reported in some trials evaluating new P2Y₁₂ inhibitors.. We aimed to review and quantify the global risk of dyspnea of recent P2Y₁₂ inhibitor drugs, and evaluate its association with the reversibility profile of P2Y₁₂ inhibitors.. A database search (March 2013) retrieved randomized controlled trials (RCTs) comparing new antiplatelet drugs (ticagrelor, prasugrel, cangrelor, elinogrel) with clopidogrel. The primary outcome was the incidence of dyspnea. Placebo-controlled trials were excluded. Meta-analysis was performed and estimates were expressed as risk ratio (RR) and 95% confidence intervals (95% CIs). Dyspnea incidence was evaluated according to the reversibility profile of P2Y₁₂ antagonists.. We found eight RCTs including 41,289 patients. Prasugrel was not associated with an increased risk of dyspnea (RR 1.09, 95% CI 0.93-1.27), whereas ticagrelor (RR 1.95, 95% CI 1.37-2.77), cangrelor (RR 2.42, 95% CI 1.36-4.33), and elinogrel (RR 3.25, 95% CI 1.57-6.72) showed an increased risk of dyspnea. Reversible inhibitors significantly increased the risk of dyspnea compared with the irreversible inhibitor, prasugrel, through adjusted indirect comparison (RR 1.99, 95% CI 1.40-2.82).. The reversible P2Y₁₂ antagonists ticagrelor, cangrelor, and elinogrel have an increased incidence of dyspnea in increasing order when compared with irreversible P2Y₁₂ inhibitors such as clopidogrel or prasugrel.

Viewpoint: reversible nature of platelet binding causing transfusion-related acute lung injury (TRALI) syndrome may explain dyspnea after ticagrelor and elinogrel.
There may be a universal mechanism explaining dyspnea after ticagrelor and elinogrel, namely, transfusion-related acute lung injury (TRALI). Indeed, recent clinical trials with ticagrelor (DISPERSE, DISPERSE-II, and PLATO), and elinogrel (INNOVATE PCI) revealed double-digit rates of dyspnea after novel reversible antiplatelet agents. In contrast, dyspnea is not associated with conventional non-reversible agents such as aspirin, or thienopyridines (ticlopidine, clopidogrel, or prasugrel) suggesting distinct mechanism of shortness of breath after ticagrelor and elinogrel. The adenosine hypothesis has been offered to explain such adverse association. However, despite obvious similarity between ticagrelor and adenosine molecules, the chemical structure of elinogrel is entirely different. In fact, ticagrelor is a cyclopentyl-triazolo-pyrimidine, while elinogrel is a quinazolinedione. Since both agents cause dyspnea, the adenosine hypothesis is no longer valid. In contrast, the reversible nature of platelet inhibition attributable to both ticagrelor and elinogrel causing premature cell ageing, apoptosis, impaired turnover due to sequestration of overloaded, exhausted platelets in the pulmonary circulation are among potential autoimmune mechanism(s) resulting in the development of a TRALI-like reaction, and frequent dyspnea. Despite expected benefit for better bleeding control, further development of reversible antithrombins is severely limited due to the existence of a potentially universal serious adverse event, such as TRALI-syndrome with dyspnea as a predominant clinical manifestation. Since TRALI is an established number one contributor to mortality after blood transfusions, ticagrelor death "benefit" in PLATO is challenged further.
