044 Increase of sympathetic nervous in patient with vasospastic angina

Direct evidence of sympathetic hyperactivity in patients with vasospastic angina.

BACKGROUND The autonomic nervous system is reported to be involved in the pathogenesis of vasospastic angina (VSA). Studies based on heart rate variability analysis have shown conflicting results with both a reduction and an enhancement of sympathetic nervous system (SNS) activity in patients with Prinzmetal's variant angina, but direct assessment has never been performed. The aim of our study ...

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...

Morphological Characteristics of Coronary€Arteries in Patients With€Vasospastic Angina

V asospastic angina (VSA) is a variant form of angina in which chest pain typically appears without provocation, is accompanied by transient ST-segment elevation, and usually resolves spontaneously or with rapid-acting nitroglycerin. Although VSA usually occurs in angiographically normal or near-normal coronary arteries, intravascular ultrasound studies (IVUS) have demonstrated early atheroscle...
