Fatty Acid Binding Proteins (FABPs) are small cytoplasmic proteins that play a crucial role in the intracellular transport of long-chain fatty acids and other lipophilic substances. Among them, Heart-type FABP (H-FABP) is predominantly expressed in cardiac muscle tissue and is rapidly released into the bloodstream following myocardial injury, making it a valuable early biomarker for acute coronary syndromes.
