The essentials on implantable cardiac defibrillators

Each year, 50,000 sudden deaths occur in France, whose main cause is an extreme excitement of cardiac contractions. In this figure, the use of an implantable defibrillator ventricular may have a salutary effect.

Automatic Implantable Ventricular defibrillators (IAD) allow each year saved thousands of lives around the world.

The essentials on implantable cardiac defibrillators

Effective prevention
50,000 sudden deaths occur each year in France. A main cause of these deaths is an extreme runaway of cardiac contraction (ventricular tachycardia – TV) which can become totally chaotic and ineffective: it is ventricular fibrillation (VF). This accident may cause reversible cardiac arrest (syncope) or (sudden death). Continue reading “The essentials on implantable cardiac defibrillators”

The secrets of the voltage

Blood pressure is the blood pressure in the arteries. Essential step for any consultation, measuring the voltage, however, remains mysterious. What are the two numbers? When can we talk about high blood pressure? How does a blood pressure monitor? Doctissimo made the point on all of these issues that care you about.

In the body, arteries serve the lactating mothers. They lead the blood from the heart to the body’s different tissues, providing cells oxygen vital to their survival. At each contraction of the heart, the blood is expelled with strength of heart and powered cavities in these pipes. To perform their function in a satisfactory manner, they must remain flexible and not clogged (fat free).

The secrets of the voltage

Systolic and diastolic
The arrival of this blood wave exerts pressure on the walls of the artery, as would the water arriving in a garden hose. This contraction of the heart, or systole, pressure corresponds to the highest measured when taking voltage. This is the systolic blood pressure.

After systole occurs a phase of relaxation, or diastolic, in which the heart relaxes and fills. The pressure exerted by the blood on the artery walls is then lower. It corresponds to the lowest number, or diastolic blood pressure. Continue reading “The secrets of the voltage”

What is Cardiology?

Cardiovascular diseases are the leading cause of death in France. In addition to the general practitioner, cardiologist following some patients said to be at risk. Relying on more specific examinations and therapeutic arsenal more effective specialist takes your health very heart.

1. What is Cardiology?
Cardiology is the study of the functioning of the cardiovascular (heart and vessels) device and diseases affecting it.


2 – What are the diseases that treats the cardiologist?
Cardiovascular diseases are very numerous. Without claiming to be exhaustive, it nevertheless include the main: high cholesterol, heart failure, hypertension, myocardial infarction, pericarditis, endocarditis, pulmonary embolism, rhythm disorders…

3 – A time consult a cardiologist?
After consultation with your doctor, he may direct you to a cardiologist. In this case only, the consultation with the specialist you will be refunded. Continue reading “What is Cardiology?”

Phlebitis, thrombosis, embolism: what are your risks?

Phlebitis and embolism are both severe and relatively common but little-known conditions. The origin of these phenomena: thrombosis, a blood clot blocking an artery. How such accidents occur? Can we reduce the risk? The point with Doctissimo.

When blood clots form in a vein, the support is easy. On the other hand, when it comes to a deep vein (phlebitis), there is urgency. The clot (called thrombus) risk standing out, cause abrupt obliteration of a blood vessel, it is the most often pulmonary embolism. Hence the importance of carefully to know the risk factors for this disease.

Emergency situations
If you have a deep pain in a calf, accentuated when you raise your foot must be think of phlebitis. A quick reference to your attending doctor, followed if necessary an ultrasound will depart (or confirm) the hypothesis. Continue reading “Phlebitis, thrombosis, embolism: what are your risks?”

New treatments for heart failure

A range of new drugs have come to enrich the therapeutic arsenal available to physicians to treat heart failure, which is a serious condition.

With age, sometimes the heart become gradually unable to ensure its pump function, which leads to eject blood into the circulation during each of her contractions. Some diseases such as myocardial infarction, high blood pressure or, more rarely, early damage to the heart muscle (cardiomyopathy) can also promote this state of fact by reducing the ability to eject from the heart (myocardial infarction, cardiomyopathy) or by increasing the resistance to the flow of blood (hypertension). In any case, result is the onset of heart failure that causes an enlarged, reflexively mechanism or dilation of the heart Chambers.

heart failure

After years of evolution, heart failure can affect lung function by causing the appearance of edema in the alveoli. While the left side of the heart is often only to be concerned at the beginning of the disease, congestive heart failure can reach the right side of the heart in a second time and lead to a stagnation of blood in the liver and the legs, which may increase in volume.

Expansion of the use of external defibrillators

In a cardiac arrest, the use of defibrillators to increase the chances of survival. Widely disseminated in public places across the Atlantic, the use of these devices remained limited in France. But a new decree has changed the situation.

There are each year in France between 30,000 and 60,000 heart attack. Against this scourge and in case of ventricular fibrillation, the prompt issuance of a suitable electric shock can restore a normal heart rhythm and save the person. External defibrillators today to do this with ease. Their dissemination should rapidly increase.

external defibrillators

Benefits against heart attacks
We know that more relief are involved early, the more the chances of survival. Every minute that passes reduces the chances of 10%. Ventricular fibrillation (VF) is spontaneously lethal. In the absence of support in less than 10 minutes, the chances of survival are stabilisation. On the other hand, if the victim receives an electric shock during the first minute, they are greater than 90%. Low weight and small size, automatic or semi-automatic equipment are able to analyse the heart rate prior to the issuance of a life-saving shock, a system of possible malfunction and even assistance to the actions to be carried out by the vocal instructions.

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”.

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”

Risk factors for women

Cardiovascular diseases, men and women are not equal. Indeed, the risk of developing a problem are higher in men. But beyond this controversial inequality, specifically female risks exist. Discover them to better avoid!

Because they appear on average 10 years later in women than in men, it was long believed the fair sex spared problems cardiovascular1. However, different studies allowed to identify unisex risk and hazard-specific factors women2.3.

Risk factors for women

General risk factors
Cholesterol: When there is excess cholesterol can be deposited on artery walls, forming fatty plaques that can thicken over time (atheroma plates). If the calibre of the arteries is reduced, blood flows more poorly and clots can form (risk of angina pectoris, sudden death, cerebral vascular accidents, Arteritis, etc.). To learn more, check out our animation “Cholesterol and heart attacks” ; Continue reading “Risk factors for women”

Should we be afraid of the metabolic syndrome?

Past two decades allowed a sharp decline in deaths from cardiovascular disease. But today, the mortality decline more… According to some experts, this trend would have an origin: the metabolic syndrome. Zoom on a silent enemy.

Ahead of cancer, cardiovascular disease is responsible for 17 million deaths each year. In France, it is the first cause of mortality with 180,000 deaths a year. While the current policies seem to mark the steps, the discovery of a new enemy could revive the fight against this scourge.

heart and stroke

Cardiovascular mortality drop more!
No fewer than 120,000 people are treated each year for myocardial infarction and 130 000 for a stroke. And 20 million people are affected by these diseases prevention approaches. The origin of this carnage, the risk factors are identified: tobacco, physical inactivity and obesity, high blood pressure, diabetes mellitus, too high levels of lipids – fat – in the blood that is. Continue reading “Should we be afraid of the metabolic syndrome?”

Prevent cardiovascular disease, it is possible!

Cardiovascular disease is responsible for 180,000 deaths a year in France, often in connection with individual risk taking. Meeting in symposium at the initiative of the French Federation of Cardiology, hospital cardiologists made the point on cardiovascular risk factors.

Aside from heredity, gender and age, the main cardiovascular risk factors are editable and are therefore those that prevention Act: cholesterol, high blood pressure, smoking and physical inactivity.


Prevention, a major issue!
Among these factors, the less expensive and cannot “easily” be modified is stopping smoking: tobacco judgment prevents thrombosis and myocardial infarction, decreases by 50% the risk of recidivism and mortality when he was arrested after the occurrence of a heart problem. A study ** for example showed that between 1975 and 1994, smoking has declined from 20% in Scotland, allowing to avoid 36% of cardiovascular.
