This editorial refers to "Plasma homocysteine in obstructive sleep apnoea"2 by A. Svatikova et al. on page 1325

Sleep-disordered breathing syndromes are recognised as an important factor for increased morbidity in cardiovascular diseases.1,2 They are characterised by the presence of repetitive episodes of ventilation cessation (apnoea), or airflow reduction (hypopnoea), or both during sleep. This leads to hypoxia, hyperkapnia, several-fold increase in chemoreflex-activated sympathetic activity with consequent peaks in blood pressure exceeding 200/100 mmHg, increased heart rate, frequent arousals, and sleep fragmentation.

In the diagnosis of sleep-related disorders, apnoea is defined as cessation of airflow for a minimum of 10 s while hypopnoea is defined as at least a 30% reduction in airflow accompanied by at least a 4% decrease in oxygen saturation.3 The sleep apnoea syndromes are divided into obstructive (OSA) and central (CSA) types. OSA is characterised by apnoeas associated with continuous respiratory efforts, despite cessation of airflow, . . . [Full Text of this Article]
