  • Abstract
  • Look Inside

A 61-year-old male visited our hospital complaining of chest oppression in the morning. He was diagnosed as multivessel-vasospastic angina by ergonovine intraco-ronary arterial provocation. 201T1 SPECT showed areas with decreased accumulation in the anterior and inferior walls, but no myocardial accumulation of 123I-β-methyl -p-iodophenylpentadecanoic acid (123I-BMIPP) was ob-served. We analyzed CD36 expression in blood cells using a flow cytometer and found there was a type I CD36 deficiency.

The CD36 molecule of human blood cells is known as a transporter of long-chain fatty acids. Hense, CD36 may have an important role for myocardial uptake of long-chain fatty acids as well as 123I-BMIPP. The absence of myocardial 123I-BMIPP uptake may be due to CD36 deficiency, especially type I . This case demon-strated that a genetic factor may be involved in coro-nary vasospasm.
