Cardiac thromboembolism: cardiac sources of embolism

…stroke constitutes 87% of all stroke cases and is further divided into the following categories: Lacunar stroke or lacunar infarct (occlusion of small penetrating arteries)…

Stent Thrombosis: Timing, Causes, Diagnosis, and Prevention

…recurrent infarction, or acute coronary occlusion. Stent thrombosis may occur within hours or days of implantation or many months to years later. Recurrent chest pain…

Posterior acute myocardial infarction (STEMI)

…is the hallmark of NSTE ACS/NSTEMI). The answer is rather simple: the probability that the patient has NSTE ACS/NSTEMI is small and the…

Myocardial Mechanics: Structure and Function of Myocardial Fibers

…Similar to vascular endothelium, the endocardium contains an underlying basement membrane and a small layer of loose connective tissue. The endocardium joins the endothelium that…

Non-ST Elevation Acute Myocardial Infarction (NSTEMI) and Unstable Angina

…deposition, culminating in a partially or fully occlusive intraluminal thrombus [5] . ACS Classification The clinical spectrum of Acute Coronary Syndromes encompasses Unstable Angina (UA), Non…

ECG manifestations of left main coronary artery (LMCA) occlusion and critical stenosis

…Clinical features Occlusion of the left main coronary artery (LMCA) abruptly interrupts blood flow to both the left anterior descending (LAD) and left circumflex (LCx…

Vulnerable Plaque and Mechanisms of Acute Coronary Occlusion

…ischemia and infarction Definition and conceptual framework Acute coronary occlusion is the abrupt or progressive reduction of coronary blood flow sufficient to produce myocardial ischaemia…

ECG localization of myocardial infarction / ischemia and coronary artery occlusion (culprit)

…artery occlusion is located. The term culprit – which means "the guilty one" – is used to denote the occluded coronary artery. In the majority of cases…

A New Approach to Acute Coronary Syndromes: Occlusion MI (OMI) vs. Non-Occlusion MI (NOMI)

…identification of acute coronary occlusion (Al Zaiti et al, 2023). The proposed transition from the traditional STEMI/NSTEMI/UA classification to the OMI/NOMI approach…

Classification of Acute Coronary Syndromes (ACS) & Acute Myocardial Infarction (AMI)

…without significant ST segment elevations on ECG. NSTE ACS is caused by partial occlusion of the artery (i.e. coronary blood flow is not completely…
