Insights
Acute coronary syndromes can occur without significant blockages. Intracoronary imaging is crucial for diagnosing non-obstructive coronary artery disease and guiding appropriate treatment.
Area of Science:
- Cardiology
- Internal Medicine
Background:
- Acute coronary syndromes (ACS) present diversely and can occur without significant coronary artery stenosis.
- Myocardial infarction with non-obstructive coronary artery disease (MINOCA) is a recognized clinical entity with varied etiologies.
Observation:
- A 56-year-old male presented with an acute coronary syndrome despite non-obstructive coronary artery disease on angiography.
- Intracoronary imaging provided critical insights into the underlying mechanism of the patient's condition.
Findings:
- The use of intracoronary imaging facilitated a precise diagnosis of the cause of the acute coronary syndrome.
- A tailored therapeutic strategy, informed by intracoronary imaging, was implemented.
Implications:
- This case highlights the importance of intracoronary imaging in managing acute coronary syndromes, especially in cases of non-obstructive coronary artery disease.
- Accurate etiological diagnosis prevents unnecessary interventions like percutaneous coronary intervention and stenting, improving patient outcomes.
Abstract:
Acute coronary syndromes have heterogeneous clinical presentations, features and prognosis. They can also occur without angiographic evidence of significant coronary artery stenosis, based on multiple causes. We report on the diagnostic and therapeutic management of a 56-year-old man with an acute coronary syndrome and angiographic evidence of non-obstructive coronary artery disease. In addition to the basic angiographic evaluation, intracoronary imaging was here helpful to understand the underlying mechanism, prompting a tailored therapeutic strategy and avoiding inappropriate treatment with percutaneous coronary intervention and stenting. This clinical case here described offers the opportunity to briefly recapitulate the most meaningful milestones in the progress in the pathophysiology of acute coronary syndromes, also focusing on myocardial infarction non-obstructive coronary artery, and to appreciate the occurrence of rare cases and consequent lessons.

Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
