FFR-CT: When Coronary Anatomy Meets Physiology
FFR-CT represents a major evolution in cardiac imaging by combining coronary anatomy with physiologic blood flow analysis. This article explains how CCTA identifies plaque, where its limitations emerge, and how AI driven FFR-CT helps determine whether coronary narrowing truly impairs circulation. The discussion also explores why integrated cardiovascular interpretation matters within the broader context of metabolic and heart health.

RNA Interference: Gene Silencing From Biology to Medicine
RNA interference is a natural gene silencing process now used in modern medicine. By targeting messenger RNA before proteins form, RNAi therapies reduce disease driving proteins with precision and durability. This article explains how RNA interference works, how it differs from traditional medications, and where it fits in lipid management, metabolic care, and emerging clinical applications.

FDA Warning: Biotin (B7) Interferes with Heart Test
The FDA has now released a new warning against biotin interference with troponin, an essential heart blood test. Biotin or vitamin B7 is a water-soluble molecule found in many over-the-counter supplements such as multivitamins, prenatal, and in those that are meant to improve or protect the health of hair, skin, and nail. Vitamin B7 is a central catalyst in many laboratory tests, especially those measuring troponin and thyroid hormone levels. When patients take high doses…

Heart strain in adults with diabetes
Technology is rapidly advancing in detecting subclinical heart disease at a much earlier stage. Global heart strain, better known as Left Ventricular Global Longitudinal Strain (LV-GLS) is such an example. It utilizes speckle tracking imaging of transthoracic echocardiography. LV-GLS identifies left ventricular dysfunction at its embryo before the ejection fraction has declined, a definition of heart failure. Investigators have tested it in a variety of heart anomalies, including ischemic, atherosclerotic, viral, hypertrophic, and dilated myopathies.…
