The objective to guide the prevention strategy is no longer the simple short-term correction of a number of cholesterol or blood pressure, but lowering the real level of risk for each individual determined by a combination of many factors.
Numbers to know by heart
Everyone should know the key figures of the prevention and regularly monitor its own settings for better operation of the “machine” heart. You can learn updated heart disease information from complete health guide.
Your LDL cholesterol (bad cholesterol):
Based on this value and the presence of known risk factors (smoking, hypertension, obesity, diabetes, history …)
In the absence of risk factors, levels of LDL-cholesterol should be less than 2.20 g / l (5.7 mmol / l);
If there is a risk factor, the concentrations of LDL-cholesterol should be less than 1.90 g / l (4.9 mmol / l);
In the presence of two risk factors, levels of LDL-cholesterol should be less than 1.60 g / l (4.1 mmol / l);
In the presence of more than two risk factors, levels of LDL-cholesterol should be less than 1.30 g / l (3.4 mmol / l);
Secondary prevention or risk equivalent concentrations of LDL-cholesterol should be less than 1 g / l (2.6 mmol / l).
Topics affected by this pure cholesterol are generally older and often accumulate more than one risk factor: moderately overweight, higher blood pressure … Read the rest of this entry »
Some preventive measures can lower the death rate from coronary heart disease. Apart from heredity, sex and age, the major cardiovascular risk factors are modifiable and are therefore those where prevention can do: cholesterol, high blood pressure, smoking and physical inactivity.
Beware dangerous plaques
The executioners of the heart Cholesterol, a substance essential for our body, can become dangerous when their blood in the blood is in excess. The excess cholesterol is deposited on artery walls including the heart (coronary arteries), forming fatty plaques that thicken over the years (atherosclerosis). Read the rest of this entry »
The conjunctivitis is the inflammation of the conjunctiva. There is talk of Keratoconjunctivitis (keratoconjunctivitis = cornea ) when the cornea and conjunctiva of the eye are affected.
The conjunctiva on the surface of the eye
When you look at an eye from the front, we guess a very thin transparent membrane covering the surface of the eye and inner eyelids is the conjunctiva. Below, there is a heavier fabric: the cornea. It is in the middle of the eye (in front of the pupil and iris). In profile, the cornea is slightly curved, it is transparent, it is through the eye sees. Read the rest of this entry »
An eye disease
The glaucoma is due to an increase in interocular pressure due to the presence of too much fluid, the humor aqueous in the anterior part of the eye.
It must be treated and monitored, because it may progress to blindness.
Interocular pressure must remain within the normal limits, a hypertension altering the other structures of the eye, especially the retina and optic nerve (behind the eyeball), essential elements to encrypt and transmit images to the brain and therefore ensure the vision.

Images behind the retina
The hyperopia is a defect of vision, is a disorder of accommodation, the image is formed behind the retina instead of forming on the retina. While the eye sees a lot of close, the images are blurred, for against the distance vision is correct in most cases. This is the opposite of myopia. Read the rest of this entry »
