Hybrid genetic‐discretized algorithm to handle data uncertainty in diagnosing stenosis of coronary arteries

, 2022
Coronary artery disease (CAD) is the leading cause of morbidity and death worldwide. Invasive coronary angiography is the most accurate technique for diagnosing CAD, but is invasive and costly.

Identification of Flow-Limiting Coronary Stenosis With PCS: A New Cost-Effective Index Derived From the Product of Corrected TIMI Frame Count and Percent Diameter Stenosis

Frontiers in Cardiovascular Medicine, 2021
Background: Identifying functional coronary stenosis with simple and cost-effective methods during invasive coronary angiography is still challenging. Corrected TIMI frame count (CTFC) is considered to be the frame count velocity of coronary blood flow ...

Relationship between neutrophils to HDL-C ratio and severity of coronary stenosis

BMC Cardiovascular Disorders, 2021
Background Lipid and inflammatory molecules play a key role in the development of inflammation. Neutrophil counts are used as markers of inflammation duration, and HDL-C is used as an anti-atherosclerosis component.

Relationship between Coronary Artery Calcium Score and Coronary Stenosis

Cardiology Research and Practice, 2023
Background. The coronary artery calcium score (CACS) is commonly employed to quantify the degree of calcification in coronary atherosclerosis. Indeed, increased coronary stenosis severity is associated with a progressive increase in CACS.
