A 72-year-old patient presented himself with typical symptoms of coron
ary heart disease and was scheduled for invasive diagnostic procedures
. Cardiac risk factors were smoking and arterial hypertension. The phy
sical examination was inconspicious. In the laborchemistry a hemoglobi
n of 79 g/l with a mean corpuscular volume of 63 fl and a mean corpusc
ular hemoglobin of 20 pg was conspicuous. The serum iron was with 42 m
u g/dl in the lower norm. Transferrin, bili-rubin and lactate dehydrog
enase were normal. Then in the gastrointestinal investigations he was
diagnosed with a leiomyoma of the intestine that led to chronic anaemi
a and additionally to chest pain characteristic for angina pectoris. A
fter the removal of the tumor and normalization of hemoglobin this pat
ient was free from symptoms of the disease. The coronary angiography r
evealed a complex stenosis of the right coronary artery with collatera
les and not significant stenosis both of the left coronary arteries. I
n patients with angina pectoris anaemia as the possible and only cause
of angina ought to be verified. It is therefore necessary after norma
lization of hemoglobin and clarification of the cause for the anaemia
to apply a test for coronary ischemia.
