Let us add “ mitral regurgitation ” in the “ Complication basket ” of hypertensive heart disease

Hypertension is a prevalent condition in the general population, as is mitral regurgitation (MR). For most of us, HT traditionally conveys a “singular meaning” that is, high pressure within blood vessels. We often forget that the origin of blood pressure begins right inside the heart, i.e, the left ventricle, which is guarded by two valves – the aortic and mitral. (Though we are aware, LVH is the classical response to HT), Obviously, there will be signiifcant consequences to the structural integrity of these valves when LV pressure is raised beyond the tolerable limit of endocardial layers that line these valves. Mind you, the bottom of the mitral valve is whipped from beneath 100 tousand times times a day & 2.5 billion times in life time at an average pressure of 140 mmHg, and during exertion, it can reach up to 200 mmHg .Apart from hemodynamic damage, It should be noted MR in HT can be consequence of altered geometery duE to LVH, (Concentric Initially & eccentric in late stages) The MR-HT link : Not to be missed It is basic bed-side teaching that any isometric activity will push the blood from LVOT towards the Mitral valve, if it is leaking. Hence, it may not be a great discovery to show that HT will aggravate MR. Now, what is the new message you are trying to tell? There is big data (Really massive one, available from 5 million HT patients Rahimi K, et al 2017) that confirms with authority that HT patients are at risk of developing both p...
