Insights

Diagnosing heart vascular disease with postmortem CT (PMCT) is challenging. This case highlights PMCT

Area of Science:

  • Forensic pathology
  • Radiology
  • Cardiovascular imaging

Background:

  • Diagnosing coronary artery disease (CAD) using unenhanced postmortem computed tomography (PMCT) presents challenges.
  • Sudden cardiac death often requires detailed postmortem examination to determine the cause.

Purpose of the Study:

  • To report a case where PMCT effectively visualized coronary artery calcification (CAC) in a sudden death scenario.
  • To evaluate the utility of advanced PMCT reconstruction techniques for cardiovascular assessment.

Main Methods:

  • Utilized unenhanced postmortem computed tomography (PMCT) for imaging.
  • Performed multiplanar reformation (MPR) and volume-rendering reconstruction (VR) for detailed coronary artery visualization.
  • Employed CaScoring software for automated calcium scoring.

Main Results:

  • PMCT clearly displayed significant coronary artery calcification (CAC).
  • The total calcium score was 640.3, exceeding the threshold for high risk.
  • Pulmonary findings, including ground-glass opacity and airway fluid, were also identified and correlated with autopsy.

Conclusions:

  • Postmortem CT (PMCT) can effectively identify and quantify coronary artery calcification (CAC).
  • Advanced PMCT techniques aid in comprehensive cardiovascular assessment postmortem.
  • PMCT serves as a valuable adjunct to traditional autopsy for diagnosing cardiovascular disease.

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 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 II: Pathophysiology and Clinical Manifestations

The pathophysiology of Acute Coronary Syndrome [ACD] involves several key processes:The main underlying cause of ACD is atherosclerosis, a chronic inflammatory disease characterized by the buildup of lipid-laden plaques within the coronary arteries.As the atherosclerotic plaque grows in the coronary artery, it may become unstable due to the formation of a lipid-rich core and a thin fibrous cap. Inflammatory cells within the plaque, such as macrophages, secrete enzymes that degrade the...

Coronary Artery Disease III: Clinical Manifestations

Coronary Artery Disease (CAD) is a primary health risk worldwide, leading to significant morbidity and mortality. The condition arises from the buildup of atherosclerotic plaques within the coronary arteries, resulting in diminished blood supply to the heart muscle.The clinical manifestations of CAD vary widely, from asymptomatic stages to severe, life-threatening conditions. Understanding these manifestations is crucial for early diagnosis and effective management.Angina Pectoris: The Warning...

Acute Coronary Syndrome V: Nursing Management

Nursing Assessment:Nursing management of acute coronary syndrome (ACS) involves taking the patient's history, focusing on primary complaints such as chest pain, dyspnea, and excessive sweating (diaphoresis), as well as other symptoms like back or jaw pain, nausea, vomiting, palpitations, dizziness, and fatigue. The nurse also reviews the patient's history of cardiac events, risk factors such as hypertension, diabetes, smoking, family history, and current medications.In the objective assessment,...
