Fructose diphosphate is mainly for intravenous drip use and is used clinically as an adjunctive therapy for acute myocardial infarction combined with heart failure, mainly to provide energy to the heart, because acute myocardial ischemia, the nutrition available to the heart plummets, and it is difficult for the heart to function properly without nutrition. Fructose diphosphate provides energy to the heart in this situation, helping cardiomyocytes to produce adenosine triphosphate to save the heart to the greatest extent possible, and with the energy supply can prevent arrhythmia, avoiding further deterioration of cardiovascular disease and giving time for treatment. Fructose diphosphate is also available in oral form, which can assist in the treatment of angina pectoris caused by myocardial ischemia, chest tightness and shortness of breath, which acts to nourish the heart muscle, and is also commonly used in cardiac surgery to prevent damage to red blood cells in extracorporeal circulation.
