Could echocardiography yield a cardiovascular profile of the tinnitus prone subject?

The possible genesis of some damage of the inner ear from a hemodynamic imbalance of functional origin, possibly linked to hypotension followed by an abnormal vasomotor regulatory activity, has been pointed out by our group over the years. As tinnitus, which is often referable to an inner ear origin, can represent a signal of incoming sufferance of the organ of Corti and may not necessarily be linked to hearing impairment, it seemed of some utility to investigate on the prevalence of tinnitus under various well monitored hemodynamic conditions. This led to observe that the prevalence of this symptom, regardless of audiological features, was increased under "aggressive" antihypertensive therapy as well as in particularly severe degree of heart decompensation. These data represent a first step and encourage in searching for a profile of subject who could be more prone to the development of tinnitus with respect to the normal population, even in absence of pathological conditions. With this aim, echocardiography is thought to be able to yield useful informations in addition to standard and ambulatory blood pressure monitoring, in order to obtain a better definition of the correlations between cardiovascular function (and related changes) and inner ear insufficient perfusion.
