Correlation between major adverse cardiac events and coronary plaque characteristics

Experimental and Clinical Cardiology

Abstract

Unstable plaque is believed to be responsible for major adverse cardiac events (MACE). To determine whether coronary computed tomography angiography (CCTA) could be used to predict future MACE. Patients undergoing CCTA between January 2008 and February 2010 were consecutively enrolled in the study. The hospital database was screened for patients who later developed acute ST segment elevation myocardial infarction (STEMI), non-STEMI (NSTEMI) or cardiac death. Plaque scores were calculated and analyzed using one-way ANOVA to examine the relationship between plaque scores and MACE. Of the 8557 patients who underwent CCTA, 1055 had hospital records available for follow-up. During follow-up, 25 patients experienced MACE including death (six patients), heart failure (two patients), STEMI (11 patients) and NSTEMI (six patients). The plaque scores were significantly increased in patients who later died, developed heart failure or experienced STEMI (P<0.05). Calcification, erosion and severe stenosis were responsible for the events (P<0.05). Mild and moderate lesions, positive remodelling, drug-eluting stent placement, occlusion and diffuse lesions were not predictive of MACE (P>0.05). Severe calcification, erosion and severe stenosis p...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
