Summary
Intravascular optical coherence tomography reveals plaque morphology in acute coronary syndromes, guiding personalized therapy. This imaging helps differentiate atherothrombotic from nonatherothrombotic causes for effective percutaneous coronary intervention.
Area of Science:
- Cardiovascular Medicine
- Medical Imaging
- Interventional Cardiology
Background:
- Acute coronary syndromes (ACS) necessitate understanding plaque morphology for tailored treatment.
- Intravascular imaging, particularly optical coherence tomography (OCT), offers detailed plaque assessment.
- Differentiating atherothrombotic (plaque rupture, erosion, calcified nodule) from nonatherothrombotic (dissection, spasm, embolism) causes is crucial.
Purpose of the Study:
- To review clinical data on OCT-assessed culprit plaque morphology in ACS.
- To highlight the role of intravascular imaging in guiding percutaneous coronary intervention (PCI) for ACS patients.
Main Methods:
- Review of clinical studies utilizing intravascular optical coherence tomography (OCT).
- Analysis of OCT-derived data on plaque characteristics in ACS.
- Evaluation of treatment strategies based on OCT findings.
Main Results:
- OCT effectively visualizes atherothrombotic substrates like plaque rupture and erosion.
- Identification of nonatherothrombotic etiologies such as spontaneous coronary artery dissection.
- Correlation between plaque morphology and optimal PCI strategy.
Conclusions:
- Intravascular OCT is instrumental in diagnosing the specific cause of ACS.
- Imaging-guided therapy improves treatment efficacy in ACS patients undergoing PCI.
- Understanding plaque morphology optimizes management and outcomes in acute coronary syndromes.

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...

207
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...

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...

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,...

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...

Atherosclerosis is a progressive disorder that leads to the thickening and narrowing of arterial walls due to plaque buildup. This condition can cause various symptoms depending on the arteries affected:Coronary Artery Disease (CAD): This condition affects the coronary arteries and may lead to chest pain (angina), shortness of breath (dyspnea), heart attacks, and other heart disease symptoms.Cerebrovascular Disease: This affects blood flow to the brain, causing transient ischemic attacks (TIAs)...
