Sudden death related to heart rate

Quasi-imprevisible and relentless, SIDS is a sudden onset of often unsuspected heart problems. Not to be confused with the sudden infant death syndrome, these ‘accidents’ kill 40,000 people each year. But the evolution of the heart rate may help identify patients at risk.

The sudden death of the adult is, as its name suggests, an unexpected death in apparently healthy person and occurring in the minutes following the onset of the first symptoms. Little-known, it appears only rarely in front of the media scene. However the death of footballer Marc-Vivien FoƩ marked the spirits.

The terrible results of sudden death
In France, the sudden death represents 5-10% of the number of deaths and nearly half of death from cardiac cause. Each year, nearly 40,000 adults die from sudden death. It is often the first (and unfortunately the last) manifestation of unsuspected heart problems. The unexpected occurrence of a death is less than an hour after the start of symptoms suggestive of ischemia (lack of irrigation) of the heart muscle (pain in the chest, shortness of breath…).

One of the challenges is to identify more vulnerable. Several risk factors are identifiable today including the overweight and obesity,high blood pressure, cholesterol and smoking. In each of these settings, it is possible to intervene by promoting good nutrition, physical exercise, smoking cessation and drug treatment. But French Inserm researchers come to identify a new risk factor for sudden death linked to heart rate1.

Keep the good heart rate
The team of Professor Xavier Jouven has highlighted the risk of sudden death was directly linked to the heart rate, or rather its modifications during and after exercise. The researchers collected 5 713 records of men aged 42 to 53. Free of any troubled heart, all had undergone a stress test standardized between 1967 and 1972. Exercise is supposed to replicate the efforts of everyday life while pedaling on a bicycle ergonomic or walking on a treadmill.

An electrocardiogram, blood pressure and responses to see how the heart reacts2.
After 23 years of follow-up, 81 patients have died a sudden death. By carefully studying the results of their stress test, it turns that they possessed a small difference between the level of maximum heart rate and resting heart rate level. The results attest as well as:

Men whose heart rate was more than 75 beats at rest have four times the risk of sudden death; At the effort, an increase in the heart rate less than 89 beats per minute multiplied by four the risk of sudden death.

A decrease of less than 25 beats per minute after the effort does more that double the risk of sudden death.An inadequate response of the heart rate during exercise is thus directly related to the risk of sudden death, but not to the other causes of cardiac death (and in particular the death by myocardial infarction).

Yet an argument to wear its sneakers!
What are the medical consequences can have this discovery? In the same way that the voltage or cholesterol levels are checked regularly, one can imagine that tomorrow, the use of a stress test allows identification of persons at risk of sudden death. An option which, according to the researchers, “deserves to be studied”. Furthermore, these results argue for a hygiene of life.

Protect his heart from generation to generation

Today, many diseases are known hereditary component. Less known that it is also the case of cardiovascular diseases where a family history can help predict the risk of each individual and thus to better prevent.

Has a loved one been a cardiovascular accident victim? Can I get sick from father to son?… Knowledge of family history allows everyone to better protect the health of his heart.

The reality of genetic factors
As for cancers of the breast, ovary, colon, allergies, asthma, diabetes, osteoporosis, several cardiovascular diseases have a heritable component: Continue reading “Protect his heart from generation to generation”

Testicular pain

Testicular pain is a frequent reason for urological consultation in young adults. They are often isolated, but can also be associated with pain or disorders of the sensitivity of the penis, perineum, pelvis and urination disorders sometimes. The causes are varied and it is not always easy to highlight.

In the first place, should be removed a local cause affecting the testicle or epididymis. The infection is rarely the cause of chronic pain while it is common in the case of acute pain accompanied then most other signs such as fever, inflammation of the scrotum limiting diagnostic doubts. It is the same for testicular torsion.

Testicular pain

Testicular tumors are rare but must be systematically eliminated by a testicular ultrasound. Varicocele is a dilation of the a gene responsible for spermatic vein scrotal late in the day. She is seen especially on the left side and is manifested clinically by a mass above testis which disappear when the patient is growing. Most often chronic pain are related to one or more cysts of epididymis, but formal proof of the participation of these cysts in painful table is never certain. Continue reading “Testicular pain”

Diet and cardiovascular disease

In France, cardiovascular problems are responsible for a third of all deaths. It is the leading cause of death among women and the second cause for men. However these death rates are the lowest in the European Union for reasons still poorly known. Food is certainly not foreign. It indeed plays a crucial role in the appearance of these cardiovascular problems.

Among the causes of cardiovascular diseases, the most important is atherosclerosis, degenerative phenomenon that reaches the arteries by reducing their elasticity and creating a decrease, or a disruption of arterial flow.

Diet and cardiovascular disease

Many factors in issue
This pathology that covers several diseases (ischemic heart disease, cerebrovascular disease etc.) is the responsibility of multiple factors: genetic, nutritional, obesity, sedentary lifestyle, tobacco, high blood pressure, diabetes. Among these causes, dietary factors have a very important place and their role in cardiovascular pathology is the object of multiple research for 50 years to better prevent and control these diseases.

Eye surgery: Lasik technique is 20 years old!

During the 20 years of LASIK, the technique of laser surgery most frequently used to correct myopia (lack of perception of objects by far), (lack of perception of objects closely) hyperopia and astigmatism, the ESCRS (European Society of Cataract and Refractive Surgeons) launches awareness campaign “LASIK, safe in our hands” **, with the hope of reassuring people still reluctant.

With the advent of Lasik, corneal refractive defects support has evolved significantly: this technique is painless, with an almost immediate effect, and surgical suites are minimal. RID forever of his glasses… until the presbyopia. Fact Doctissimo point on this revolutionary technique that repairs the vision of hundreds of thousands of people each year.

Eye surgery

Lasik, said between 20 and 40 years old
Lasik Surgery to repair the cornea refractive anomalies, either the myopia, astigmatism or hyperopia. In the case of myopia, this technique is to raise a very fine lamella of the cornea called pane and to remove below a layer whose thickness is a function to correct myopia. These two steps can be carried out using two successive lasers, femtosecond laser then the Excimer. Reserved for those whose nearsightedness is scalable, it is therefore contraindicated in less than 20 years, but particularly indicated between 20 and 40 years old. Continue reading “Eye surgery: Lasik technique is 20 years old!”

Towards the end of the glasses?

Nearsighted, farsighted, high-risk… you soon store your sunglasses in the closet. Indeed, laser, robotics and Informatics truly revolutionized the ophthalmologic surgery. Can to much to correct all defects of vision?

With universal lasers, ophthalmic surgery is now capable of true prowess. Simplified and perfectly controlled, it helps correct many vision disorders and could even increase Visual acuity.

Towards the end of the glasses

The prowess of the laser
Attention, everyone cannot benefit from these new technologies. They are today directed to patients with Visual anomalies qualified low to average. The failure of vision must not be scalable, the vision must be stabilized (in particular for myopia). Finally, to the rank of contraindications, we note certain eye diseases: glaucoma, ocular lesions due to the UV or ocular herpes. The operation is also discouraged for pregnant women.

Cataracts: surgery changing

Cataract surgery has been great progress in recent years, including the development of new methods for the extraction of the crystalline. However, complications remain possible, fortunately the more often minor.

Cataract surgery has become the most common surgery in the elderly. The technique is now well mastered and the results are, in the vast majority of cases, very satisfactory. It can be performed under general anesthesia, without hospitalization. There is thus no age limit its use, although instead, because the restoration of a satisfactory vision often allows very elderly regain a degree of autonomy.

surgery changing

A more common disease with age
It is estimated that cataracts reached more than one in five from 65, more than one in three aged over 75 and nearly two out of three aged over 85. This condition is due to the development of opacities in the lens, the transparent lens that allows the accommodation. These opacities prevent light rays pass, resulting in a decrease in vision which can be very important. The only treatment is the use of surgery. It is to remove the lens has become opaque and to replace it with an implant. Continue reading “Cataracts: surgery changing”

Glasses or lenses, how to choose?

In several defects of vision, glasses or contact lenses may be proposed. One and others each have their advantages and their disadvantages. You won’t your eyes!

Fashion accessory and instrument of high-tech, glasses are increasingly challenged by more discrete lenses. To guide you in your choices, learn about the characteristics of each.

Contact lenses, a practical and aesthetic correction
Contact lenses are primarily used in the correction of myopia (80% of cases) and, to a lesser extent, hyperopia, astigmatism and presbyopia. They are placed in contact with the cornea and cut on both sides to correct the optical anomaly.

glasses or lenses

The glasses allow light rays to focus again on the retina and not in front of it as in the myopia or back as in hyperopia. There are the rigid or semi-rigid, whose maintenance is quite easy, but which are sometimes poorly tolerated by the eye. Easier to accept flexible plastic polymer versions require careful daily cleansing with a special product. There are also disposable lenses, can keep one or two weeks in a row. In all cases, the ophthalmologist will have to check before prescribing lenses if the eye produces enough tears to support these. Continue reading “Glasses or lenses, how to choose?”

Self-medication

Green light to the free service in pharmacies
It is, self-service drug landed in pharmacies. Goal: engage the French in the management of their health and lower prices for promoted patients “responsible consumers”. But what about this development? The point with Doctissimo.

It is now done: pharmacists have the right to pass certain non-refundable drugs in front of their desk. Open access in dedicated spaces, it will therefore soon find 217 drugs meet the daily headaches (fever, headaches, colds, cough, but also smoking cessation), 12 drugs of phytotherapy and 15 homeopathic drugs. A list that could soon go.

service in pharmacies

“Open-access” more than “self-service”
First observation: this is a priori no direct link with the fight against the hole of the social security system. All of these drugs were already sold without prescription and therefore not reimbursed. What will change, it is that the patient will freely have access to mailboxes without having to ask their pharmacist. Continue reading “Self-medication”

The major health issues

Self-medication, Internet health… The behavior has changed
Explosion of internet, reimbursable medicines, care… For 10 years, the health of the French habits have changed. To assess developments in self-medication and the use of internet health, Opinion Way compares two investigations in 2000 and 2010.

The French have more recourse to self-medication? For what reasons? Is the quality of the information found on the web satisfactory? Have their expectations and habits on the health internet evolved?

The major health issues

Self-medication has increased in 10 years
In 2000, 79 per cent of the 1,000 people interviewed by the polls Opinion Way Institute declared “treat themselves” occasionally or frequently. In 2010, this practice is more French (85%), especially women. Continue reading “The major health issues”
