Insights

Emergency centre (EC) single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) effectively triaged patients with chest pain. Most discharged patients remained symptom-free, and none with normal MPI experienced adverse events.

Area of Science:

  • Cardiology
  • Nuclear Medicine
  • Emergency Medicine

Background:

  • Unexplained chest pain is a common emergency centre presentation.
  • Accurate and timely diagnosis is crucial for patient management and outcomes.
  • Myocardial perfusion imaging (MPI) plays a role in assessing cardiac ischemia.

Purpose of the Study:

  • To evaluate the clinical outcome of patients with unexplained chest pain.
  • To assess the utility of emergency centre (EC) single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) in triage.
  • To determine the safety and efficacy of EC-MPI for chest pain evaluation.

Main Methods:

  • Prospective assessment of 68 patients presenting with unexplained chest pain.
  • Triage decisions based on clinical presentation and EC SPECT MPI.
  • Follow-up at 9 months to assess clinical outcomes and symptom recurrence.

Main Results:

  • 63% (43/68) of patients were discharged directly from the EC based on clinical assessment and EC-MPI.
  • Of those discharged, 84% (36/43) remained symptom-free at 9-month follow-up.
  • No adverse clinical events were observed in patients with a completely normal EC-MPI result.

Conclusions:

  • EC SPECT MPI is a valuable tool for the safe and effective triage of patients with unexplained chest pain.
  • Normal EC-MPI results correlate with excellent short-term clinical outcomes and absence of adverse events.
  • This imaging modality can facilitate early discharge for a significant proportion of patients presenting with chest pain.

Imaging Studies for Cardiovascular System I:Echocardiography

Cardiac imaging studies encompass a wide range of noninvasive and minimally invasive techniques designed to visualize the heart's structure and function in detail. One such technique is echocardiography, which uses high-frequency ultrasound waves to produce detailed images of the heart, known as echocardiograms.
Indications: Echocardiography is utilized to diagnose heart failure, valve disorders, and myocardial infarction. It also assesses cardiac structures' size, shape, and motion, evaluates...

Pericarditis II: Clinical Features and Diagnostic Tests

Pericarditis is distinguished by inflammation of the pericardium, the fibrous sac that encases the heart. It can be acute, lasting less than six weeks, or chronic, persisting for over three months. Understanding its clinical manifestations and diagnostic findings is crucial for timely and effective management.Clinical ManifestationsWhile pericarditis can be asymptomatic, it usually presents with characteristic symptoms such as:Chest Pain: The most characteristic symptom of pericarditis is chest...

Acute Coronary Syndrome I: Introduction

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...

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...

Angina III: Clinical Manifestations and Assessment

Angina manifests as chest pain, tightness, or squeezing discomfort typically located behind the breastbone. It can radiate to the neck, jaw, shoulders, and inner aspects of the upper arms, most commonly the left arm. Patients may experience shortness of breath, fatigue, profuse sweating, dizziness, indigestion, heartburn, palpitations, anxiety, and vomiting as accompanying symptoms. This pain often lasts a few minutes and is triggered by physical exertion, emotional stress, heavy meals, or cold...
