Clinical pathways reinforce best practices and help healthcare institutions standardize care delivery. The NewYork-Presbyterian/Columbia University Irving Medical Center has used such a pathway for the management of patients with chest pain and acute coronary syndromes for almost 2 decades. A multidisciplinary panel of stakeholders serially updates the algorithm according to new data and recently published guidelines. Herein, we present the 2019 version of the clinical pathway. We explain the rationale for changes to the algorithm and describe our experience expanding the pathway to all the 8 affiliated institutions within the NewYork Presbyterian healthcare system.

Clinical pathways can optimize care both across and within institutions, but regular updates to these pathways based on new clinical trials, professional guidelines, and Food and Drug Administration approvals are essential. Herein we describe the most recent revisions to the New York-Presbyterian Hospital (Columbia University Medical Center and Weill Cornell Medical Center) clinical pathway for acute coronary syndromes and chest pain, which incorporates novel data regarding the timing and administration of P2Y12 inhibition (including the intravenous P2Y12 inhibitor cangrelor) and the appropriateness of prolonged (>1 year) dual antiplatelet therapy for the secondary prevention of ischemic events.

Clinical treatment pathways are useful to ensure that evidence-based medicine is consistently applied in hospital systems and have been shown to improve patient outcomes. Such pathways need to be regularly updated and revised by incorporating new evidence from clinical trials to ensure optimal clinical care. In 2011, we published the Columbia University Medical Center/New York Presbyterian Hospital - Clinical Pathways for Acute Coronary Syndromes and Chest Pain. This algorithm includes primary percutaneous coronary intervention for all patients with ST-segment elevation myocardial infarction and an early invasive approach for patients with non-ST-segment elevation myocardial infarction. Since our last chest pain algorithm update, the novel antiplatelet agent ticagrelor has been introduced in the United States, resulting in an important revision of our acute coronary syndrome clinical pathways. Herein, we present our updated chest pain algorithm and provide rationale for the changes that we have made to our protocol.

In 2008, we published our chest pain protocol for the management of acute coronary syndromes (ACS) and acute myocardial infarction. Our algorithm was specifically designed for our institution, which includes primary percutaneous intervention (PCI) for all ST-elevation myocardial infarctions (STEMIs) and a preferred invasive approach for non-STEMIs. Since 2008, there have been changes in the adjunctive pharmacotherapeutic armamentarium for PCI in both the STEMI and non-STEMI ACS context. In particular, recent data on the novel antiplatelet agent prasugrel, dosing of clopidogrel after PCI, and interactions with clopidogrel and other medicines and substrates, which can lead to decreased platelet response to clopidogrel, have led us to update our ACS clinical pathway. We present our updated chest pain algorithm with a brief review of the rapidly evolving changes in adjunctive pharmacotherapy for PCI, and provide rationale for the changes that we have made to our institutional protocol. Clinical pathways need to be regularly updated and revised by incorporating new evidence from clinical trials to ensure optimal clinical care.

In 2003, we published our chest pain protocol for the management of acute coronary syndromes (ACSs) and acute myocardial infarction. Our algorithm was specifically designed for our institution, which was primary percutaneous coronary intervention (PCI) for all ST-elevation myocardial infarctions (STEMIs) and a preferred invasive approach for non-STEMIs. Since 2003, there have been numerous changes in the adjunctive pharmacotherapeutic armamentarium for PCI in both the STEMI and non-STEMI ACS context. We present our updated chest pain algorithm with a brief review of the rapidly evolving changes in adjunctive pharmacotherapy for PCI and provide a rationale for the changes that we have made to our institutional protocol. Clinical pathways need to be consistently updated and revises by incorporating new evidence from clinical trials in order to maintain clinical relevance.
