1Membro do Corpo Redactorial da Revista Portuguesa de Cardiologia.
Summary
Corrected coronary opacification (CCO) differences can identify arteries with abnormal resting coronary blood flow, showing potential for diagnosing coronary artery disease. Further research is needed to explore its full diagnostic capabilities.
Area of Science:
- Cardiovascular Imaging
- Radiology
- Physiology
Context:
- Computed tomographic coronary angiography (CTCA) is used for detecting coronary artery disease.
- CTCA cannot reliably differentiate anatomical from functional stenoses.
- Assessing coronary blood flow is crucial for accurate diagnosis.
Purpose:
- To determine if corrected coronary opacification (CCO) differences within the coronary lumen can identify arteries with abnormal resting coronary flow.
- To evaluate the diagnostic performance of CCO differences in detecting abnormal coronary blood flow.
Summary:
- A study assessed 104 coronary arteries using CTCA and invasive angiography.
- Greater CCO differences were observed in arteries with significant stenoses (≥50%) and abnormal flow (TIMI grade <3).
- CCO differences accurately identified abnormal coronary flow with 88.5% accuracy.
Impact:
- This method shows promise for differentiating functional from anatomical coronary stenoses.
- CCO differences may serve as a non-invasive indicator of abnormal coronary blood flow.
- Further studies are warranted to assess its value in measuring stress coronary blood flow.

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...
01:28Imaging Studies for Cardiovascular System V: CT
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...
01:25Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT
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...
