Obstructive Sleep Apnea is causally linked to the development of systemic hypertension, with worsening AHI independently associated with an increasing risk of new hypertension, even in mild cases.

Even mild sleep apnea can silently raise your risk of developing high blood pressure. If you have risk factors like obesity or snoring, getting screened for sleep apnea is important for your long-term heart health, regardless of whether you feel tired during the day.

StrongSupportsVERY_HIGH confidence
The most compelling evidence that obstructive sleep apnea is causally related to cardiovascular disease comes from the Wisconsin Sleep Cohort Study (72). In normotensive persons who were followed for 4 years after an initial sleep study, worsening severity of obstructive sleep apnea was independently associated with progressively increasing risk for new hypertension... Even persons with very mild abnormalities in the apnea– hypopnea index (0.1 to 4.9) had 42% greater odds of developing hypertension at follow-up than did those with an apnea– hypopnea index of 0.
