Sleep Apnea Screening

Centrum kardiovaskulární péče Brno offers a self-pay sleep apnea examination — overnight monitoring that screens for obstructive sleep apnea, a condition affecting an estimated one in ten adults and strongly linked to hypertension, atrial fibrillation, daytime fatigue, and cardiovascular risk. Screening at a cardiology centre is particularly relevant: untreated sleep apnea is one of the most common reversible drivers of difficult-to-control blood pressure and recurrent arrhythmias. The clinic fits the monitoring device, the patient sleeps at home as usual, and a physician evaluates the recording — breathing pauses, oxygen desaturations, snoring, and heart rhythm — and recommends next steps, from lifestyle measures to referral for CPAP therapy.

Obstructive sleep apnea (OSA) is dramatically underdiagnosed — most people who have it do not know, because the breathing pauses happen while they sleep. The classic clues are loud snoring, witnessed pauses in breathing, gasping awakenings, unrefreshing sleep, morning headaches, and daytime sleepiness. Less obvious but equally important clues are cardiological: blood pressure that stays high despite multiple medications, nocturnal blood-pressure peaks, and atrial fibrillation that keeps returning after treatment. **Why a cardiovascular centre screens for sleep apnea:** During each apnea episode, oxygen levels fall and the sympathetic nervous system surges, spiking blood pressure and stressing the heart hundreds of times per night. The evidence links untreated OSA to resistant hypertension, atrial fibrillation recurrence after cardioversion or ablation, heart failure progression, and stroke. For Centrum kardiovaskulární péče — a centre whose core specialism is treating atrial fibrillation and other arrhythmias — identifying and treating sleep apnea is part of getting durable rhythm-control results, which is why the screening sits directly on its self-pay menu (1,300 Kč). **How the examination works:** The patient attends the clinic for device fitting and instruction. The portable monitor records through the night at home — typically airflow at the nose, breathing effort, blood oxygen saturation, pulse, snoring, and body position. Home monitoring captures more natural sleep than a laboratory environment. The device is returned the next day and a physician analyses the recording, quantifying the apnea–hypopnea index (the number of breathing disturbances per hour) and the depth of oxygen desaturations. **Results and next steps:** Mild findings may be addressed with weight reduction (the nutrition clinic on-site can support this), positional therapy, alcohol reduction, and follow-up. Moderate-to-severe findings are referred for definitive therapy — most commonly CPAP (continuous positive airway pressure), which abolishes apneas from the first night and measurably improves blood pressure, daytime energy, and arrhythmia control. Where sleep apnea coexists with arrhythmias or hypertension, the cardiology team integrates the findings into one treatment plan. **Who should be screened:** Habitual loud snorers; anyone whose partner has witnessed breathing pauses; patients with resistant hypertension or recurrent atrial fibrillation; drivers and professionals struggling with daytime sleepiness; and people with obesity, a thick neck circumference, or type 2 diabetes — all strong OSA risk factors.
