Sleep Smart                   Cardiovascular Consequences

What can happen if sleep apnea is left untreated?

Hypertension and heart failure are strongly linked with sleep apnea. OSA appears to be a cause of hypertension. It appears that sleep can be either a cause or an effect of heart failure. Recent trials have demonstrated that treating sleep apnea in patients with heart failure is beneficial.


.Refractory hypertension or hypertension requiring multiple antihypertensive agents often respond well to treatment of Obstructive sleep Apnea.






Cardiovascular consequences of OSA:1

o hypertension (high blood pressure)

o heart failure

o atherosclerosis (heart attacks, angina)

o atherosclerosis (stroke)

o atrial fibrillation

o ventricular arrhythmias

o Pulmonary hypertension

Untreated OSA can result in higher risks of hypertension, cardiac arrhythmias or cardiac arrest, and higher mortality rates
