Vasospastic Angina in Identical Twins

Vasospastic Angina in Identical Twins

BACKGROUND The clinical conditions of various diseases, including coronary artery disease, are determined by genetics and the environment. Previous investigations noted the significance of genetic mutations and polymorphisms in cases of coronary spasm. CASE REPORT We report on monozygotic identical twins who almost simultaneously presented with vasospastic angina. The 58-year-old younger twin...

Narcolepsy in identical twins.

Narcolepsy has been observed in chronic encephalitis, cerebral arteriosclerosis, brain tumour, and following trauma, but when these cases are excluded there remains a group without demonstrable brain pathology. The existence of this idiopathic group has been a controversial subject. Among the more impressive evidence is that suggesting a hereditary factor in idiopathic narcolepsy. To date this ...

Long lasting spasticity in controlled vasospastic angina.

OBJECTIVE To evaluate changes in coronary artery spasticity in patients with vasospastic angina who had been stable for years under continuous drug treatment. METHODS Follow up coronary angiography was performed under intracoronary ergonovine provocation in 27 well controlled patients with vasospastic angina and no organic stenosis; the tests were done > 24 months after the initial coronary a...
