Cardiac sympathetic activity in 22q11.2 deletion syndrome.
AIM 22q11.2 deletion syndrome (22q11.2DS) affects catechol-O-methyl-transferase (COMT), which involves the degradation of norepinephrine (NE). Clinically, adults with 22q11.2DS are at increased risk for sudden unexpected death. Although the causes are likely multifactorial, increased cardiac sympathetic activity with subsequent fatal arrhythmia, due to increased levels of NE, should be consider...
متن کاملPlasma leptin levels and cardiac sympathetic function in patients with obstructive sleep apnoea-hypopnoea syndrome.
BACKGROUND The control of body weight and cardiac sympathetic function in patients with obstructive sleep apnoea-hypopnoea syndrome (OSAHS) are important because both factors have significant effects on the mortality of these patients. It has recently been reported that OSAHS has a significant effect on the secretion of leptin, a hormone involved in the control of body weight and sympathetic ne...
متن کاملPersisting myocardial sympathetic dysfunction in takotsubo cardiomyopathy
A 73-year-old woman without a cardiovascular history was admitted with chest discomfort, dizziness, and nausea after an emotional meeting with the staff of a nursing home. She experienced the same complaints some years before when her father died. On admission the patient was in cardiogenic shock. Auscultation of the heart revealed a grade 3/6 systolic murmur radiating to the left axilla. The e...
متن کاملTakotsubo Syndrome
T akotsubo syndrome (TTS) is an acute heart failure syndrome that predominantly affects post-menopausal women. It is characterized by substantial morbidity and mortality, which equal those of acute coronary syndromes (ACS) and are still underappreciated (1). TTS and ACS share many clinical features on admission, and an estimated 1% to 2% of all patients with suspected ACS are finally diagnosed ...
متن کاملSympathetic overactivity and plasma leptin levels in Rett syndrome.
Rett syndrome (RTT) is a severe developmental-neurological disorder, characterized by profound and progressive loss of intellectual functioning, occurring after a period (of at least 6 months) of normal development with classic stereotype hand movements, gait ataxia, jerky truncal ataxia, deceleration of brain and body organ growth and cardiac dysautonomia. Pathogenesis of sympathetic overactiv...
