[This corrects the article DOI: 10.1371/journal.pone.

Increased plasma lactate level is associated with subclinical cardiovascular damage in patient with non-dipping hypertension.

Objective: To evaluate the difference of plasma lactate level between dipping and non-dipping hypertension, and to investigate the effects of lactate on subclinical cardiovascular damages in dipping and non-dipping hypertension.

Methods: According to 24 h ambulatory blood pressure monitoring, 236 patients with dipping and 152 with non-dipping hypertension were included. Clinical characteristics were collected and compared between dipping and non-dipping groups.

Continuous Positive Airway Pressure Treatment Reduces Mortality in Elderly Patients with Moderate to Severe Obstructive Severe Sleep Apnea: A Cohort Study.

Obstructive sleep apnea (OSA) is much more prevalent in older people than in middle-aged or young populations, and has been associated with cardiovascular disease. Continuous positive airway pressure (CPAP) is the first-line therapy for OSA, but its long-term clinical benefit in the elderly is unclear. Here, we carried out a prospective cohort study to explore the survival rate and incidence of cardiovascular events in elderly patients with moderate to severe OSA who did or did not receive CPAP treatment.

[Investigation on long-term efficacy of CPAP treatment for the elderly with obstructive sleep apnea syndrome].

Objective: To investigate the long-term efficacy of continuous positive airway pressure (CPAP) treatment for the elderly with obstructive sleep apnea syndrome (OSAS).

Methods: Case control study was performed among 106 elderly with obstructive sleep apnea syndrome (OSAS). They were divided into treatment group (n=34) and control group (n=72), based on whether they underwent long-term CPAP treatment or not.

[Effect of obstructive sleep apnea syndrome on blood lipid and blood glucose in elderly hypertensive patients].

Objective: To investigate the effect of obstructive sleep apnea syndrome (OSAS) on blood lipid and blood glucose in elderly hypertensive patients.

Method: a One hundred and seven elderly hypertensive patients received examinations by polysomnography and according to the apnea-hypopnea index (AHI), the patients were divided into four groups, namely uncomplicated hypertension group (n=23) and 3 hypertension groups with mild (n=31), moderate (n=29) and severe (n=24) OSAS. The fasting and 2-hour postprandial plasma glucose, glycosylated hemoglobin (HbA1c), total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), Apo-A, and Apo-B of these patients were measured.

[Clinical analysis of coronary artery disease in elderly patients with sleep disordered breathing].

Objective: To understand the prevalence of sleep disordered breathing (SDB) in elderly patients with coronary artery disease (CAD) and explore the relations between SDB and CAD.

Methods: Sixty-two elderly patients with and 18 without CAD identified by coronary angiography underwent examinations by polysomnography (PSG). Left ventricular ejection fraction (LVEF) was measured by 99Tc equilibrium radionuclide angiography.
