A recent study proposes that cytomegalovirus (CMV), a prevalent viral infection affecting 60-99% of adults globally, may be a significant contributor to high blood pressure, a key risk factor for heart disease, stroke, and kidney disease. This study, conducted by researchers at Beth Israel Deaconess Medical Center (BIDMC) and published in the May 15 issue of PLoS Pathogens, sheds new light on the potential impact of common viral infections on cardiovascular health.

Middle ear infections, also known as otitis media, can develop when congestion from allergies or colds obstructs the Eustachian tube. This blockage leads to fluid and pressure buildup, creating an environment where bacteria or viruses can thrive and cause infection. These infections are notably the most frequent illness leading to doctor visits.

The Eustachian tube plays a crucial role in equalizing air pressure on either side of the eardrum. If it becomes blocked, reduced pressure in the middle ear can cause the eardrum to be pulled inward, resulting in a full, plugged sensation in the ear. This condition not only affects ear health but can also influence overall well-being.

Secondary hypertension, often linked to hyperaldosteronism, where excess aldosterone is produced by the adrenal glands, significantly impacts blood pressure. This hormone influences the kidneys to retain sodium and water, increasing blood volume and, consequently, blood pressure. A common cause of this condition is a benign growth in one of the adrenal glands.

Furthermore, high blood pressure can cause turbulent blood flow in the carotid artery, potentially leading to pulsating sounds in the ear. Other vascular malformations and disorders, such as aneurysms, can also cause pulsatile tinnitus.

Sporadic high blood pressure should not be overlooked, as varying readings between home and the doctor’s office can be a sign of underlying health issues. Continuous monitoring is essential for accurate diagnosis and management.

The Eustachian tube’s blockage, a common issue, can isolate the middle ear, affecting pressure regulation and mucus drainage. This condition is crucial to understanding ear health and related complications.

The COVID-19 pandemic has also been linked to new-onset high blood pressure, possibly due to the virus’s effects on cardiac function and blood pressure regulation through ACE2 receptors. Acute kidney injury, commonly seen in hospitalized COVID-19 patients, is also associated with hypertension development.
