Long-term adherence to nasal continuous positive airway pressure therapy by hypertensive patients with preexisting sleep apnea.
Although positive screening for and treatment of obstructive sleep apnea (OSA) have been recommended for patients with cardiovascular problems, patient adherence to nasal continuous positive airway pressure (CPAP) therapy primarily for a cardiovascular concern is unknown. Therefore, this study aimed to determine the adherence to CPAP therapy by hypertensive patients with OSA after a screening test performed regardless of OSA-related symptoms. ⋯ The adherence and use level in this population may not be satisfactory but are comparable with those in previous sleep center reports treating symptomatic OSA patients. Thus, the present results would encourage hypertensive patients to undergo positive screening for OSA, regardless of OSA-related symptoms. However, an outcomes study with the same cohort is needed.

Safety and efficacy of adaptive servo-ventilation in patients with severe systolic heart failure.
It is unclear whether adaptive servo-ventilation (ASV) is safe and effective in patients with severe systolic heart failure (HF). Our aim in this study was to estimate the safety and efficacy of ASV therapy for patients with severe systolic HF. ⋯ Our study demonstrated that ASV therapy is safe and effective for use in very severe systolic HF patients as well as in relatively mild systolic HF patients.

Clinical impact of acute hyperglycemia on development of diabetes mellitus in non-diabetic patients with acute myocardial infarction.
Acute hyperglycemia (AH) after the onset of acute myocardial infarction (AMI) is a manifestation of transient abnormal glucose metabolism that may reflect AMI severity, and thus be a predictor of poor prognosis. However, it remains unknown whether AH may predict development of de novo diabetes mellitus (dn-DM) in non-diabetic AMI patients. ⋯ Admission AH was a predictor of dn-DM in non-diabetic post-AMI patients. Renin-angiotensin system inhibitors were associated with reduced incidence of dn-DM in post-AMI patients with AH.

Comparative StudyComparison of immediate results and mid-term follow-up of surgical and percutaneous closure of ruptured sinus of Valsalva aneurysm.
The past decade has witnessed considerable improvement in implantation techniques for percutaneous closure of ruptured sinus of Valsalva aneurysm. This study was undertaken to compare the immediate results and mid-term follow-up of traditional surgery and percutaneous closure of ruptured sinus of Valsalva aneurysm in China. ⋯ Percutaneous closure is an attractive alternative to surgery in selected patients with ruptured sinus of Valsalva aneurysm for the better clinical advantages and economic benefits.

Aortic stiffness is increased in patients with premature coronary artery disease: a tissue Doppler imaging study.
Atherosclerosis and arterial stiffening may coexist and the correlation of these parameters in patients with premature coronary artery disease (CAD) has not been well elucidated. Tissue Doppler imaging of the ascending aorta may be used in the assessment of elastic properties of the great arteries. ⋯ Arterial stiffness is increased in patients with premature CAD. EAo of the anterior wall of ascending aorta measured with pulse-wave TDI echocardiography is correlated with arterial stiffening and is decreased in patients with premature CAD.
