What cardiologists should know about sleep?
We spend one-third of our lives sleeping. Normal healthy sleep is a state of reduced physiologic stress, lower heart rate, and blood pressure (BP). Sleep disorders like insomnia and obstructive sleep apnoea (OSA) impair sleep quality and increase the risk of cardiovascular disease (CVD) including hypertension, heart failure (HF), and atrial fibrillation. Increasing sleep health can improve quality of life, mood, and may reduce cardiovascular morbidity in selected patients.
