Cholesterol: why everyone should know its rate?

Is cholesterol today figure of enemy food number 1. The relationship between cholesterol and atherosclerosis and cardiovascular disease is now indisputable. Yet we talk about good and bad cholesterol, how distinguish them? Discover whence the cholesterol and the risk associated with it.

What is than cholesterol?
Fatty substance essential to life, cholesterol is involved in the manufacture of all cells, hormones… but its increase in the blood and in the walls of the arteries can be dangerous (atherosclerosis).


Where does cholesterol come from?
Part of the cholesterol in our body is manufactured by the liver. In addition, we draw in from food such as eggs, offal, butter, whole milk..

What is the risk of excessive levels of cholesterol?
The increase in the level of cholesterol in the blood is at the origin of the coronary artery disease (angina pectoris, myocardial infarction). It is one of the major risk factors of these diseases with tobacco, high blood pressure and diabetes.

… It is one of the 4 executioners of the heart.
The atherosclerotic plaque
The excess cholesterol is deposited in the walls of arteries including the arteries of the heart (coronary arteries), which leads to the fact:
Reduce their size by forming plaques;
Make it more and more difficult the passage of blood;
To promote the formation of blood clots (thrombosis).
When the blood no longer, starved of oxygen, cells die. It is the ischemic accident which leads to the obstructed artery, myocardial infarction, stroke or Arteritis of the lower limbs.

Good or bad cholesterol
Blood cholesterol is transported by the lipoprotein (FAT + protein).
Some favour the formation of the atherosclerotic plaque, what are LDL, low density (low density lipoproteins).
Others are rather beneficial because they allow the elimination of excess cholesterol in the cells: these are HDL, high-density (high density lipoprotein).
People with high LDL cholesterol and/or a decreased HDL cholesterol have more risk for coronary artery disease.

Cholesterol and lipoprotein abnormalities have a variety of causes.
Some are genetic (Familial Hypercholesterolemia for example).
Others are food (dietary fats or alcohol excess).

For a heart without tobacco

Five million deaths are attributable to smoking each year worldwide, including 35% by cardiovascular disease is two times more than by lung cancer. Active or passive smoking, all are affected by this danger.

This year marks the gradual implementation of the law banning smoking in public places. On this occasion, the French Federation of Cardiology (FFC) and the French society of Cardiology (SFC) are committed in 2007 for a “heart without tobacco”.

No small risk tobacco
Smoking is the second most important risk of myocardial infarction, closely behind excess cholesterol. It is a full cardiovascular risk, especially for young since issue 80% of victims of myocardial infarction under 45 years old are smokers. Most people smoke, more it is exposed to this risk. Thus, there is no “small risk” tobacco since the risk increased 63% from 1 to 9 cigarettes per day. Continue reading “For a heart without tobacco”

Together, improve management of myocardial infarction

Each year, about 100,000 people suffer from myocardial infarction in France. Although mortality has significantly decreased since 10 years, 13% of patients still die in the year following the accident. To improve support, health authorities have established a programme of priority actions.

The heart 2007-2010 program aims to further reduce mortality and complications of myocardial infarction by improving the different steps of its support. To do this, many recommendations for action and 30 good clinical practice indicators have been determined. Their development would help to assess the reality of the expected improvement.

Evocative acute chest pain? Call the 15!
The phase known as acute myocardial infarction, the pain to the proper medical intervention, is a crucial step of the optimization of the support. Indeed, on the 13% of deaths in the first year, 7% are held during this initial stage! But only a quarter of the myocardial infarction have recommended optimal course: 15 (UAS) call and direct transfer in interventional cardiology.

Is sex dangerous for the heart?

Can sex be originally of myocardial infarction? Rarely, this accident is due to such an activity. However, some experts talk about a doubling of the risk! Not panic, however, the danger remains very low in absolute terms and in most cases, the carnal love is a “practice” activity.

Classically, cardiologists are wary of Monday morning. Numerous epidemiological studies have, in fact, described a number of myocardial infarction more important this day there. This strange phenomenon has been assigned with the change of pace associated with the passage of the weekend the week and stress that accompanies many people home from work. Consumption of alcohol, which is traditionally important weekend in Anglo-Saxon and Scandinavian countries, could also play a negative role at this level (the alcohol acting on blood clotting).

The false repose of the Warrior
In 2001, a study in Toulouse by the team of Professor Jean Ferrières (INSERM) has however led to conclusions somewhat different1. The researchers analyzed the number of myocardial infarction according to the days of the week, using: Continue reading “Is sex dangerous for the heart?”

Core business, the role of hypertension

High blood pressure affects nearly 10 million French. Very many men are involved. Among them, 1 in 7 suffer from due to hypertension itself or the prescription erectile dysfunction. Attention, these problems are often initially bad treatment monitoring. Only solution: overcome its reluctance and talking to his doctor.

When you’re heart, Affairs of the heart are not always easy. On the one hand, sexual failures are more common than other men, on the other hand, the fear of heart attack fears that these love stories end badly… How to share the fantasy and the reality?

High blood pressure

Hypertension and erectile dysfunction
High blood pressure (hypertension) is defined by a pressure blood pressure systolic over 14 (140 mm of mercury) or the pressure blood diastolic over 9 (90 mm of mercury). According to the latest epidemiological data established by the national Committee to combat high blood pressure, it is estimated that 10 million people are high blood pressure and that 7 million are under treatment.

Among this large population, men can have any erectile dysfunction due to their high blood pressure and/or because of the treatment that they follow. A major study epidemiological American (Massachusetts Male Aging Study) carried out in 1994 shows that erectile dysfunction concern 9.6% of 1290 men 40 to 70 years surveyed. Among treated hypertensive, this percentage was 15%, either 1 patient treated on 7.

Alteration of the arteries
Why high blood pressure promotes the occurrence of erectile dysfunction? There are two main causes:

This condition causes an alteration of the arteries, whose structure is altered due to the increase in pressure. In addition, high blood pressure promotes atherosclerosis, i.e. the thickening and hardening of artery walls. The passage of the blood in the arterial tissue is so disabled and the quality of the erection decreased;

Some treatments for high blood pressure may also have an impact on the sexuality of the patient.
Some studies3 report a fix to get and maintain an erection that is greater in hypertensive patients treated compared to the untreated. The mechanisms involved are still pretty mysterious.

What is less, this is the bad monitoring of the treatment of erection problems. Impact on the sexual life of the hypertensive patient treated even sometimes causes a discontinuation of treatment, which is not without consequences on cardiovascular fate3.

Despite these side effects, few patients would be able to overcome their reluctance and to discuss it with their doctor. “If you go beyond the psychological course express the problem, it is possible, more or less easily, to erectile dysfunction solutions. In some cases, a simple modification of the treatment can solve the difficulties; elsewhere on the contrary, it will take both to reassure the patient and possibly prescribe a treatment of the erectile dysfunction which, most often, poses little problems of interaction with the treatment hypertensive.”said Dr. Nicolas Danchin, hypertension specialist at a conference on the relationship between hypertension and erectile dysfunction. The only absolute contraindication is the association of nitrates and inhibitors of phosphodiesterase.

Learn how everyday actions

Stroke is the leading cause of disability in adults and the second cause of dementia. These sad records reflect the life of patients who will have to relearn daily gestures through a very grueling rehabilitation. Returning to the home will be facilitated by special attention of environment and the use of some material aid.

Our brain can compensate for some damage by activating brain areas until then non-exploited. This extraordinary ability, “brain plasticity” is possible only if it is stimulated intensively and sustainably. It is one of the tasks of rehabilitation.

everyday actions

Start rehabilitation as soon as possible
Reduce complications and neurological sequelae, retrieve the wealth of functions (market, language, manual skill, vision…) are all objectives of the rehabilitation. Earlier it could be implemented and the consequences can be minimized. However, the location of the brain lesion also plays a significant role. The balance sheet will be heavier that it operates in a highly specialized functional area. Continue reading “Learn how everyday actions”

Headaches: a risk of stroke?

Migraine or not, chronic headaches affect millions of people. Before the violence and intensity of some pain, many are those who have questions about the State of their brains after the crisis. A number of studies point to an increased risk of stroke. Doctissimo is an update on these relations still not solved.

Commonly referred to as “brain attacks”, cerebral vascular accidents (CVAS) are the third cause of death behind heart disease and cancer. Their prevention relies on regular medical follow-up and a good understanding of the risk factors. Is it necessary to add to an already long list chronic headache?

Women migraine and stroke, attention!
Statistical studies show that there more than migraine in people who have suffered a stroke. However, such observations make it possible – it for as many consider migraine as a risk factor for stroke? Continue reading “Headaches: a risk of stroke?”

Inform to save lives

125,000 patients annually and nearly 50 000 deaths. For the survivors, serious physical, cognitive or psychological sequelae. Such is the sad record of cerebral vascular accidents in France. However, this disease suffers in Europe and in France of a cruel lack of recognition particularly. Dr. Jacques Boulliat, president of the association stroke, tells us more.

Doctissimo: What are the tasks and milestones of the Association stroke?
Dr. Jacques Boulliat: Our association France stroke was established in 1998. We have set for mission information to the general public as well as professionals. Although strokes are the third leading cause of death and the leading cause of disability, this disease remains too often unknown to the general public. Our actions are designed to help patients and their families as well as to promote research. We thus organise a wiretapping, public meetings, networking between patients and the families of victims.

Inform to save lives

We are instead antennas departmental in Saône- et -Loire, Isère and Meurthe- et -Moselle. A social service and website should soon see the day. Continue reading “Inform to save lives”

Cerebral vascular accident

Stroke prevention passes by a better understanding of the risk factors but also by that of warning signals. Thus, sustainable ischemic stroke are to almost one-third preceded by transient ischemic symptoms are brief. Too often overlooked, they must bring to consult. With Doctissimo, learn to recognize them!

Awareness of stroke warning signs could save thousands of lives each year. This prestigious American Heart Association is easily transposable to our country. As are very certainly the figures attesting to their lack of knowledge. According to a telephone survey in Georgia, only 39% of those interviewed could cite a stroke alert signal… The results would certainly not be different in France. What are the warning signs and symptoms of stroke?
The transient ischemic should not be underestimated!

Cerebral vascular accident

A transient ischemic (attack TIA) is a stroke which sometimes stealthy symptoms go unnoticed. Yet, they represent real warning signs since nearly a third of sustainable ischemic or cerebral infarction are preceded by one such episode. Continue reading “Cerebral vascular accident”

The cerebral vascular Accidents in figures

Commonly referred to as “brain attacks”, accidents cerebrovascular (stroke) are the third cause of death behind heart disease and cancer. But it is the first cause of heavy disability and the second cause of dementia in the Western world. In France, 130,000 people each year are victims of a stroke and half in will keep serious sequelae. In a few figures, check out the dire consequences of this disease.

Strokes are also known as attacks, stroke or stroke. The origin of this disease, there is a disruption of the blood supply of the brain. Devoid of oxygen and other essential compounds, certain cells in the brain die. Specifically, stroke represent two types of reality.


Ischemic and hemorrhagic accidents
Stroke can result:

The obstruction of a blood vessel by a clot, reducing blood flow in a brain area. The clot may occur locally in a small artery or come from the heart or the wall of a large cervical artery lesion (carotid arteries and vertebral). One speaks then of ischemic stroke ;

Of the rupture of a vessel, causing bleeding. The blood spreads and damages the brain tissue around. The location and the size of the hematoma determine its severity. Talking about in this case of hemorrhagic stroke, brain haemorrhage or cerebral hematoma.
Nearly 85% of stroke are ischemic in nature. The consequences of stroke depend on many factors: the speed of recovery of blood flow, the duration of oxygen deprivation and cerebral localization of the accident.

A serious problem of public health
In addition to the ageing of the population, the number of stroke increases and represents a serious public health problem today.
The risk of stroke increases with age. Nearly three quarters of the patients were over 65. And after 50 years, the incidence doubles every 10 years. According to the association France stroke, the number of stroke per year is estimated on the basis of age:

Estimate of the number of stroke per year
