 DEFINITION
The pressure excess in the arteries supported during a period of years and not treated it can lead to a big number of complications. The most important are described.
ARTERIOSCLEROSIS
When the blood glasses are subject to a supported pressure increase, they answer being increased, what makes them less flexible. In these stiff arteries there are fixed by facility the fats that circulate in excess in the blood. At level of the arteries of the kidneys, the arteriosclerosis does that flow comes less to the kidney, and the kidneys answer liberating regirl, a hormone that in turn causes an increase of the TA. This exaggerates the HTA and hurts moreover on the blood glasses.
HYPERTENSIVE CARDIOPATÍA
When the arteriosclerosis fond of the glasses that feed the cardiac muscle or myocardium (the called coronary glasses), the heart turns out to be forced to work more to support the blood flow in the textiles. In some cases it does it increasing of size, with a hypertrophy of the cardiac muscle, becoming more rigid and less effective. The final score can be the congestive heart failure: The heart remains behind in the pumping what the circulating blood needs, and the liquids stagnate in the whole organism.
RENAL ILLNESS
The fifth part of the blood pumped by the heart goes to the kidneys. These leak the products of undone and help to support the suitable chemical values. Also they control the balance of acids, salt, and water.
The kidneys are especially sensitive to the changes in the blood flow that result from the HTA and from his complications. They cannot work well if the flow decreases, so the low flow there does that they secrete more of the enzyme regirl, who does that all the arteries of the body are restricted, raising the TA in an attempt of restoring this renal flow. Nevertheless, ultimately, what takes place is a vicious circle that ends in more HTA and worse renal function, up to coming to the renal mistake.
ICTUS
Latin term that it includes to all the called cerebral vascular accidents. When the arteriosclerosis fond of the glasses of the brain, a blood blockade can happen somewhere of the brain for a tightness or a clot (cerebral thrombosis), or a break of a glass (cerebral hemorrhage). All this is much more frequent in hypertense, and the risk diminishes on having treated the HTA. TO SEE ALSO
