Insights

Dual antiplatelet therapy (DAPT) guidelines need adjustment for East Asian patients undergoing percutaneous coronary intervention (PCI). This review examines optimal antiplatelet strategies considering unique East Asian risk profiles and the

Area of Science:

  • Cardiology
  • Pharmacology
  • Clinical Trials

Background:

  • Current dual antiplatelet therapy (DAPT) guidelines by ACC/AHA and ESC are based on trials with limited East Asian representation.
  • East Asian populations exhibit distinct thrombophilia and bleeding risk profiles compared to white populations.
  • The 'East Asian paradox' suggests similar ischemic event rates post-PCI despite higher on-treatment platelet reactivity during DAPT.

Purpose of the Study:

  • To review evidence and provide expert consensus on optimal antiplatelet strategies for East Asian patients.
  • To address the specific needs of East Asian individuals undergoing percutaneous coronary intervention (PCI) and with acute coronary syndromes.

Main Methods:

  • Evidence-based review of randomized controlled trials and observational data.
  • Expert consensus development by the World Heart Federation.
  • Analysis of P2Y12 inhibitors (clopidogrel, prasugrel, ticagrelor) efficacy and safety in diverse populations.

Main Results:

  • Existing DAPT trial data inadequately represents East Asian patient populations.
  • Pharmacogenetic differences may influence P2Y12 inhibitor response and outcomes in East Asians.
  • A potentially different therapeutic window for platelet reactivity may be appropriate for East Asian patients.

Conclusions:

  • Current DAPT recommendations may not be universally applicable to East Asian patients.
  • Further research and tailored antiplatelet strategies are warranted for this demographic.
  • This consensus statement aims to guide appropriate antiplatelet treatment for East Asian patients.

Antiplatelet Drugs: Prostaglandin Synthesis, P2Y12 and Glycoprotein IIb/IIIa Inhibitors

Antiplatelet drugs emerge as frontline defenders against the insidious threat of thromboembolic diseases, where abnormal clots obstruct vital blood vessels. These drugs stand as bulwarks, inhibiting platelet aggregation and clot formation, thereby mitigating the risk of life-threatening conditions like myocardial infarction, coronary artery disease, and thrombotic strokes.
Prostaglandin synthesis inhibitors, exemplified by the widely known aspirin, wield their power by irreversibly acetylating...

Acute Coronary Syndrome III: Diagnostic Studies

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...

Acute Coronary Syndrome IV: Interprofessional Care

IntroductionThe management of Acute Coronary Syndrome (ACS) aims to minimize myocardial damage, preserve myocardial function, and prevent complications.Initial ManagementInpatient management involves continuous cardiac monitoring, preferably in an ICU, focusing on blood pressure, serum sodium, potassium, and creatinine levels, and urine output. Ongoing pharmacologic management is crucial for stabilizing the patient.Supplemental Oxygen: Administer supplemental oxygen if oxygen saturation is...

Atherosclerosis III: Management

Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

Peripheral Artery Disease III: Interprofessional Care

Peripheral Artery Disease (PAD) is characterized by narrowed arteries that diminish blood flow to the extremities. Effective management of PAD requires an interprofessional approach involving various healthcare professionals. The critical aspects of interprofessional care for PAD patients focus on risk factor modification, drug therapy, exercise therapy, nutrition therapy, critical limb ischemia care, and interventional radiology and surgical procedures.The primary treatment goal for PAD...
