APOB vs LDL — The Right Atherogenic Marker
Apolipoprotein B (apoB) is the structural protein on every atherogenic lipoprotein particle — LDL, VLDL, IDL, chylomicron remnants, and lipoprotein(a). Each of these particles carries exactly one apoB molecule, which means circulating apoB…
Cleerly / AI-Analyzed CT Coronary Angiography
Cleerly is an AI-powered analysis platform applied to coronary CT angiography (CCTA), the contrast-enhanced cardiac CT that visualizes both calcified and non-calcified plaque in the coronary arteries. Where coronary artery calcium (CAC) scoring…
Coronary Artery Calcium (CAC) Scoring
Coronary artery calcium scoring is a non-contrast CT scan of the heart that quantifies calcified atherosclerotic plaque in the coronary arteries. The Agatston score, derived from the area and density of calcified deposits, has been the standard…
Lipoprotein(a) — Testing and Management
Lipoprotein(a), abbreviated Lp(a) and pronounced "L-P-little-a," is an LDL-like lipoprotein particle with a specific protein attachment — apolipoprotein(a) — that makes it independently atherogenic. Roughly 20% of the global population — about 1.4…

Losartan — The Uricosuric ARB with a Marfan and TGF-β Story
Losartan (Cozaar, first FDA-approved 1995) is the prototype angiotensin II receptor blocker. It shares the class-level mechanism (selective AT1 receptor blockade), core indications (hypertension, diabetic nephropathy, heart failure, cardiovascular…
Nattokinase — Fibrinolytic Enzyme Supplement
Nattokinase is a serine protease enzyme extracted from natto, the traditional Japanese fermented soybean food. It was discovered and characterized by Sumi and colleagues in 1987 as the active fibrinolytic constituent in natto, with strong in vitro…
Specialized Pro-Resolving Mediators (SPMs)
Specialized pro-resolving mediators (SPMs) are a family of bioactive lipid mediators derived enzymatically from omega-3 fatty acids — primarily EPA and DHA. They include the resolvins (E-series from EPA, D-series from DHA), protectins (from DHA),…
Practices & Lifestyle
High-Dose Niacin for Lipids
Niacin (nicotinic acid, vitamin B3) at pharmacologic doses (typically 1,500-2,000 mg/day) has substantial effects on the lipid profile — raising HDL by 15-35%, lowering triglycerides by 20-50%, lowering LDL by 5-25%, and lowering lipoprotein(a) by…
Low-Dose Colchicine for Cardiovascular Inflammation
Colchicine is an alkaloid extracted from autumn crocus (Colchicum autumnale), with documented medical use for over 2,000 years. Its modern indications include acute and prophylactic gout, familial Mediterranean fever, and pericarditis. Over the past…
