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

…with ACS. Clinical manifestations therefore commonly include recurrent myocardial ischaemia, recurrent infarction, or acute coronary occlusion. Stent thrombosis may occur within hours or days of…

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

…linking). Concurrent activation of the coagulation cascade leads to thrombin generation and fibrin deposition, culminating in a partially or fully occlusive intraluminal thrombus [5] . ACS…

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

…or sudden cardiac death. The resulting extensive ischemia causes immediate myocardial stunning (akinesia) and electrical instability. Fewer than 1% of patients with ST elevation myocardial…

Vulnerable Plaque and Mechanisms of Acute Coronary Occlusion

…or severe, myocardial necrosis. It most commonly reflects atherothrombosis: disruption of an atherosclerotic plaque followed by platelet activation and coagulation, with formation of an intraluminal…

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

…alleviate ischemic chest pain may lead to hemodynamic collapse in patients with right ventricular ischemia or infarction. Recognizing ECG signs of right ventricular involvement is…

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

…reperfusion therapy. This approach fails to identify a substantial proportion of patients with acute coronary occlusion (ACO) who present without diagnostic ST elevation, often resulting…

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

…partial occlusion of the artery (i.e. coronary blood flow is not completely obstructed). NSTE ACS typically presents with ST segment depressions and/or T…
