Sleep apnoea, both central and obstructive disordered breathing, commonly occurs in patients with heart failure. Obstructive sleep apnoea occurs both in systolic and diastolic heart failure and is best treated with nasal positive airway pressure devices. Central sleep apnoea occurs primarily in systolic heart failure and therapeutic options are

reduced longevity.1 Heart failure can be due to systolic or diastolic left ventricular dysfunction. Most patients with heart failure have primarily systolic dysfunction. In two-thirds of patients with systolic dysfunction, the cause is coronary artery disease.2 However, patients may also have nonischaemic causes of cardiomyopathy such as hypertension, valvular heart disease, myocarditis, system...

background: although the positive effects of cardiac rehabilitation (cr) for patients with heart failure have been known, only a small proportion of such patients have been referred for comprehensive cr. the aim of this study is to compare the extent to which a cr program improved the exercise capacity and modifiable risk factors of patients with and without impaired systolic function. methods:...

Background and objectives: The kidneys of chronic kidney disease (CKD) patients do not have enough function and hemodialysis (HD) is a common procedure for their treatment. HD requires vascular access surgery (VAS) and arteriovenous fistula (AVF) is a low-complication method in VAS. However, different rates of AVF failure have been reported worldwide which can cause repeating s...

Despite the fact that up to half of all heart failure occurs in patients without evidence of systolic cardiac dysfunction, there are no universally accepted diagnostic markers and no approved therapies for heart failure with preserved ejection fraction (HFpEF). HFpEF, otherwise known as diastolic heart failure, has nearly the same grim prognosis as systolic heart failure, and diastolic heart fa...
