Vulnerable Plaque and Mechanisms of Acute Coronary Occlusion

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

Atherosclerosis: Pathogenesis from Fatty Streak to Plaque Rupture

… neovascularization and intraplaque haemorrhage; calcification and remodelling; episodic plaque disruption followed by thrombosis. Atherosclerotic disease usually evolves over decades. Intimal thickening may be present during…

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

Introduction to Coronary Atherosclerosis, Plaques, Atherothrombosis Coronary atherosclerosis is a chronic, progressive, and highly dynamic inflammatory disease of the arterial wall. It is characterized by…

Intravascular Imaging: IVUS and OCT for PCI Optimisation

…ischemia and infarction Definition and Pathophysiology Intravascular imaging comprises catheter based techniques that directly visualize the coronary lumen, vessel wall, plaque, thrombus, and implanted stents…

Coronary Artery Calcium Scoring: Prognostic Use in Practice

…Myocardial ischemia and infarction Definition and Pathophysiology Coronary artery calcium (CAC) scoring is a non invasive method for detecting and quantifying calcified coronary atherosclerotic plaque…

Coronary CT Angiography and CAD-RADS Reporting

…tomographic angiography (CCTA) is a non invasive anatomical examination that depicts the coronary arterial lumen, atherosclerotic plaque, and the severity and distribution of coronary stenosis…

Statin Intolerance and Statin-Associated Muscle Symptoms

…oxidative stress, endothelial function, plaque stability, thrombogenic responses and immune activity. Statin intolerance refers to adverse effects attributed to statin treatment that improve or resolve…

Type 2 Myocardial Infarction: Mechanisms and Management

…By definition, acute atherothrombotic plaque disruption is not a feature of Type 2 MI. The pathophysiology of Type 2 MI is fundamentally distinct from that…

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

…infarction Classification, diagnosis and definitions of acute coronary syndromes (ACS) and acute myocardial infarction (AMI) Acute coronary syndromes occur when atherosclerotic plaques disrupt, resulting in…

Diagnostic Criteria for Acute Myocardial Infarction: Cardiac troponins, ECG & Symptoms

…rupture or erosion of a vulnerable (unstable) atherosclerotic coronary plaque. Upon such damage, the plaque exposes highly thrombogenic materials which activate circulating platelets and coagulation…
