Acute Coronary Syndrome IV: Interprofessional Care

194
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...

Acute Coronary Syndrome I: Introduction

690
Acute Coronary Syndrome (ACS) encompasses a spectrum of heart conditions caused by sudden obstruction of coronary arteries, typically resulting from the rupture of an atherosclerotic plaque and subsequent thrombus (blood clot) formation. This obstruction can lead to partial or complete blockage of blood flow, causing varying degrees of myocardial ischemia or infarction.ACS includes the following clinical entities:Unstable Angina (UA)Non-ST-Elevation Myocardial Infarction (NSTEMI)ST-Elevation...

Venous Thrombosis III: Interprofessional Care

254
Venous thrombosis requires effective prevention and treatment strategies to improve patient outcomes and reduce potential complications.Prevention StrategiesHealthcare providers must prioritize preventing venous thromboembolism (VTE) for all adult patients upon admission. Interventions depend on bleeding and thrombosis risk, medical history, current medications, diagnoses, planned procedures, and patient preferences. Patients on bed rest should change positions every two hours and, if not...

Acute Coronary Syndrome III: Diagnostic Studies

190
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...

Area of Science:

  • Neuroradiology
  • Emergency Medicine
  • Stroke Imaging

Background:

  • Computed tomography (CT) is the primary imaging modality for acute stroke treatment selection.
  • Accurate CT interpretation is critical for timely stroke management decisions.

Purpose of the Study:

  • To review CT-based workup for ischemic stroke.
  • To focus on practical skills, interpretation challenges, mimics, and pitfalls in CT imaging for treatment decisions.

Main Methods:

  • Review of CT findings, pearls, and pitfalls in image interpretation.
  • Discussion of CT angiography for identifying large-vessel occlusions (LVO).
  • Exploration of multiphase CT angiography and perfusion CT for infarct volume estimation when MRI is unavailable.

Main Results:

  • CT is essential for selecting patients for intravenous tissue plasminogen activator (tPA) up to 4.5 hours post-stroke.
  • CT angiography is the standard for identifying LVO for endovascular thrombectomy (EVT) up to 24 hours post-stroke.
  • CT-based methods can help distinguish patients who will benefit from EVT.

Conclusions:

  • A systematic approach to CT interpretation is necessary for rapid triage and treatment decisions.
  • Understanding CT findings aids in evaluating vessel patency and guiding stroke interventions.
  • CT plays a vital role in both primary and comprehensive stroke center management.
