The aim of this research was to study the effect of Obstructive Sleep
Apnea (OSA), snoring and the episodes of cessation of breathing on heart
failure, cardiac arrhythmia and coronary artery diseases. Thirty patients
has been suffering from OSA since 7 years were subjected to scintigraphic
study using the radiopharmaceutical (Thalium201) and Tc99m
MIBI) using General Electric-Infinia Hawkeye 4` gamma camera. Present
study showed that apnea causes obstruction of right coronary arteries,
ischemia of the lower part of posterior wall of left ventricle, infarction
of postero-lateral wall of left ventricle, ischemia in the apico-septal
wall and infarction of the infero-septal wall of left ventricle. In conclusion,
OSA increases the risk of stroke and death, disturb sleep level, accompanied
with hypertension, atrial fibrillation and erectile dysfunction. Treatment
by the aid of Continuous Positive Airway Pressure (CPAP) resulted in improvement.
Comparing the hormone level and scintigraphy is under investigation.
