Hypertension seriously affect the entire internal organs, especially the heart, brain, kidneys, lungs, eyes, peripheral vascular ...

 

For heart:
Hypertension caused to the heart, heart failure. High blood pressure makes the innermost layer of the vessel wall cracks. From there, fat and blood leukocytes squeeze through the cracks to fall down the hole
into the blood vessels, making the vessels to thicken, narrow and lose elasticity, reduces the amount of oxygen to feed the heart. Consequently appear arrhythmia, angina, heart failure and myocardial infarction can cause sudden death.
Hypertension also causes bulging snake aorta, atherosclerosis, inflammation leg artery.
For the brain:
Hypertension causes transient ischemic attacks manifested by headache, dizziness, vertigo ... Hypertension causes complications such as cerebral ischemic stroke, brain hemorrhage, stroke resulted in hemiplegia, paralysis completely, even death.
In addition, some symptoms of hypertensive encephalopathy as vomiting, dizziness, convulsions, coma ...
For kidney:
Hypertension damage cell membranes of the kidney, renal artery stenosis, renal failure
For the eyes:
Hypertension causes blurred vision, retinal hemorrhage caused blindness, also known as retinopathy due to hypertension.
All this complication in critically ill health made gradually, causing multiple disabilities (62% and 49% of stroke angina by increasing blood pressure) and sudden death or reduced life expectancy. On the financial side, the increased cost burden for patients and families.
Why hypertension is called "the silent killer"?
Natural progression of hypertension as follows: in the 10-30 age, blood pressure begins to rise, the first increase in cardiac output, blood pressure gradually rose early in the 20-40 age (this time in human vascular resistance Peripheral excel, have hypertension, but the attack was not known) then the real hypertension at the age of 30-50 and finally hypertension complications at the age of 40-60.
Hypertension progresses silently in the first 15-20 years. People with hypertension are still living and working normally with the disease is slowly destroying the body, causing the death of rodents, fresh news. Hypertension often not showing symptoms until the patient was hospitalized know your blood pressure. Hypertension causes reduced life expectancy from 10 to 20 years. Therefore, the cardiologists call hypertension is a silent killer.
