Medical Description
Hypertension, or high blood pressure, is characterized by high blood pressure on the artery walls. In stressful situations or during physical exertion, it is normal blood pressure rises. In people with high blood pressure, tension remains high at all times, even at rest or in the absence of stress.
Hypertension is not a disease in itself. However, long term, it is an important risk factor:
* Heart failure: by imposing an additional workload on the heart, hypertension can cause depletion of the heart muscle;
* Of angina, myocardial infarction and stroke: high blood pressure means that the blood exerts greater pressure on the artery walls, making them fragile and increases the risk that the artery Hangs by atherosclerosis;
* Kidney problems (renal failure) and eyes (injury to the retina can lead to blindness): Again, due to the weakening of blood vessels.
