Acute Coronary Syndrome III: Diagnostic Studies

67
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...

Imaging Studies for Cardiovascular System V: CT

126
Cardiac computed tomography (CT) scanning is an advanced cardiac imaging technique that utilizes CT technology, with or without intravenous (IV) contrast, to produce accurate cross-sectional virtual slices of specific areas of the heart, coronary circulation, and major blood vessels such as the aorta, pulmonary veins, and arteries. The computer processes these slices to generate three-dimensional images. Multidetector CT (MDCT) is a rapid form of CT scanning that captures multiple slices...

Imaging Studies for Cardiovascular System IV: CMRI

172
Cardiovascular magnetic resonance imaging, or CMRI, is a non-invasive diagnostic test that employs a magnetic field and radiofrequency waves to create precise images of the heart and arteries. It provides comprehensive information about cardiac anatomy, function, perfusion, and tissue characterization without ionizing radiation.IndicationsCMRI diagnoses various heart conditions, including tissue damage from heart attacks, ischemic heart disease, myocarditis, aortic issues (tears, aneurysms,...

Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

196
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Area of Science:

  • Cardiology
  • Medical Imaging

Background:

  • Microvascular dysfunction is a significant cause of chest pain in patients with and without obstructive coronary artery disease.
  • Accurate diagnosis is crucial for guiding treatment and improving prognosis.

Purpose of the Study:

  • To summarize advanced imaging techniques for assessing microvascular dysfunction.
  • To review current evidence on these modalities and their relation to invasive evaluations.

Main Methods:

  • Overview of diagnostic capabilities of Positron Emission Tomography (PET).
  • Discussion of emerging roles for Cardiovascular Magnetic Resonance (CMR) and Cardiac Computed Tomography (CCT).

Main Results:

  • PET is the gold standard for diagnosing microvascular abnormalities.
  • CMR and CCT are increasingly valuable for microcirculation assessment.
  • Identifying microvascular disease is fundamental for characterizing patients with chest pain and no epicardial coronary disease.

Conclusions:

  • Advanced imaging plays a vital role in diagnosing microvascular dysfunction.
  • These techniques aid in patient characterization, medical strategy management, and prognosis improvement.
