Prophylactic and/or therapeutic agent for cardiovascular complications of diabetes
An object of the present invention is to provide a drug that contains a compound for inhibiting neutral lipid accumulation in cardiovascular tissue or cells and has an excellent prophylactic or therapeutic effect on cardiovascular complications of diabetes. The present invention relates to a prophylactic and/or therapeutic agent for cardiovascular complications of diabetes, the agent containing a compound (preferably a medium-chain fatty acid and/or a medium-chain triglyceride) for inhibiting neutral lipid accumulation.
1. A method for treating a cardiovascular complication of diabetes, the method comprising a step of administering a compound for inhibiting neutral lipid accumulation in cardiovascular tissue or cells to a diabetic patient or a diabetic non-human mammal with a cardiovascular complication of diabetes, the compound being a medium-chain triglyceride, the medium-chain triglyceride being a simple or mixed acid triglyceride composed of a saturated fatty acid, the saturated fatty acid being capric acid alone or caprylic acid and capric acid,
wherein the method excludes administering fish oil.
2. The method according to claim 1 , wherein the cardiovascular complication of diabetes is a case where improvement is not achieved by a cholesterol-lowering agent and/or surgical treatment.
3. The method according to claim 1 , wherein the cardiovascular complication of diabetes is a disease with neutral lipid accumulation in a cardiac blood vessel.
4. The method according to claim 3 , wherein the cardiac blood vessel is narrowed or blocked by accumulated neutral lipid and is one or more selected from the group consisting of coronary arteries, aortas, branched and peripheral arteries that branch from an aorta, and arterioles.
5. The method according to claim 1 , wherein the cardiovascular complication of diabetes is a disease with a sign of myocardial hypertrophy or diffuse or concentric coronary artery stenosis.
6. The method according to claim 1 , wherein the cardiovascular complication of diabetes is diabetic arteriosclerosis, a disease resulting from diabetic arteriosclerosis, diabetic nephropathy, diabetic retinopathy, or diabetic neuropathy.
7. The method according to claim 6 , wherein the diabetic arteriosclerosis is atherosclerosis.
8. The method according to claim 6 , wherein the disease resulting from diabetic arteriosclerosis is cerebrovascular disease, ischemic heart disease, or arteriosclerosis obliterans.
9. The method according to claim 8 , wherein the cerebrovascular disease is cerebral infarction or moyamoya disease.
10. The method according to claim 8 , wherein the ischemic heart disease is angina pectoris, myocardial infarction, arrhythmia, or heart failure.
11. The method according to claim 1 , wherein the compound is administered into a cardiac blood vessel.
