Relationships between Heart Chamber Morphology or Function and Respiratory Parameters in Patients with HFrEF and Various Types of Sleep-Disordered Breathing.

Sleep-disordered breathing (SDB), i.e., central sleep apnea (CSA) and obstructive sleep apnea (OSA), affects the prognosis of patients with heart failure with reduced ejection fraction (HFrEF).

Severe sleep apnea as a predictor of failure to respond to cardiac resynchronization therapy.

Background: The response to cardiac resynchronization therapy (CRT) is suboptimal in one-third of patients.

Objectives: The study aimed to evaluate the impact of sleep-disordered breathing (SDB) on the CRT-induced left ventricular (LV) reverse remodeling and response for CRT in patients with ischemic congestive heart failure (CHF).

Methods: A total of 37 patients aged 65.

The usefulness of telemedicine devices in patients with severe heart failure with an implanted cardiac resynchronization therapy system during two years of observation.

Background: Heart failure (HF) remains a disease with a poor prognosis. Telemonitoring is a medical service aimed at remote monitoring of patients.

Aim: The study aimed to identify the clinical relevance of non-invasive telemonitoring devices in HF patients.

The beneficial impact of cardiac rehabilitation on obstructive sleep apnea in patients with coronary artery disease.

Study Objectives: To assess the impact of cardiac rehabilitation for decreasing sleep-disordered breathing in patients with coronary artery disease.

Methods: The study included 121 patients aged 60.01 ± 10.

[How to avoid cardiovascular consequences of the obstructive sleep apnea syndrome?].

Obstructive sleep apnea syndrome (OSAS) is caused by periodical upper airway occlusion during sleep resulting in snoring, episodes of apnea and excessive daytime sleepiness. OSAS is a risk factor for hypertension, arrhythmias, conduction disorders as well as stroke, coronary artery disease, chronic heart failure and pulmonary hypertension. Early polygraphy and polysomnography and continuous positive airway pressure (CPAP) treatment reduce risks of cardiovascular diseases (CVD) in patients with OSAS.
