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 Foé 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.

A heart for life World Day heart 2004

The world heart day! This year, children and adolescents are at the centre of all concerns. Indeed, the World Heart Federation intends to set alarm bells ringing before the devastation caused by the unhealthy lifestyle of children.

Poor eating habits, smoking, lack of exercise and high blood pressure are the bed of heart disease and stroke. To prevent these evils, we urgently need to play the card of the prevention from the earliest age.

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.

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.

Sexual activity and heart disorders in humans

The practice of sexual activity is often compatible with the existence of cardiac disorders. Nevertheless, it is normal to wonder following a cardiovascular accident, illness, on its capabilities. Shed light on these cases of heart.

The sexual act is extraordinary and leads to a transformation of the metabolism that can legitimately worry about the convalescent or the former patient. The heart beats 70-80 beats per minute at rest, monte and 120 to 160 beats per minute and blood pressure sometimes increases.

Sexual activity

Patients are even less confident that some have decreased their sexual form related to their State of health or their anxiety, their concern. Sometimes, these are drugs that cause sexual dysfunction. Continue reading “Sexual activity and heart disorders in humans”

Sensitive heart: should it be?

In case of cardiac problems, erectile dysfunction are often in the background. Yet their impact on the quality of life can no longer be ignored. “When can I again make love?”, “my drugs are not at the root of my problem?”, “erection inducers are dangerous for the heart?”… The specialists of the national college of cardiologists of France make the point.

14E Congress of the national college of cardiologists from France, when professionals made the point on the theme “Heart and sexual activity”. Doctissimo was present and returns on erection problems in the cardiovascular patient.

Sensitive heart

Often problematic heart cases
Patients with heart disease are often faced with erectile dysfunction. “But this is not always easy to deal with his doctor about sexual problems…” shows a convalescent patient of a myocardial infarction.

A large proportion of erectile dysfunction is organic, that is caused by physical diseases. Among the largest enemy conditions of erection, on view in mind a disturbing Duet: diabetes and vascular disorders.

An important epidemiological study (Massachusetts Male Aging Study) in 1994, shows that the erectile dysfunction would concern themselves with 9.6 percent of men 40 to 70 years. Among treated hypertensive, this percentage was 15%, or 1 in 7 patients! More recently, a Spanish study1 even said the increased risk of sexual failures depending on the condition.

Attention to compliance!

How can we explain these figures? There are two main causes:
Cardiovascular diseases such as hypertension, atherosclerosis (cholesterol, diabetes…) cause a change of the walls of the arteries. The passage of blood in the vessels is then disabled and impaired erection. Participating in the session “Heart and sexual activity”, Dr. Delphine Behr-Roussel even suggests that erectile dysfunction can be indicative of the evolution of cardiovascular disease;

Many drugs can also have an impact on the sexuality of patients. Some studies2 reported a fix to get and maintain an erection in treated versus untreated hypertensives. These side effects are not inconsequential. “I tried and arrested all medicines to treat my high blood pressure, they made to me helpless” sometimes hear doctors in consultation. Poor monitoring of treatment is often the venue in case of erectile problems.

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.

Eat for better sleep

A healthy life lie at a regular time, quiet in a room cool enough … But with a good diet! And even if there is no miracle food for sleep, some easy to follow dietary rules can help get a better night. You have trouble sleeping? And if the problem was on your plate? Here are some tips to not count sheep …

Spread the exciting
Coffee, tea and cola drinks should be avoided during the afternoon because caffeine they contain is very exciting for the nervous system, and its action may occur for several hours. Even chocolate (including any component, theobromine, caffeine is close), can have an exciting effect if consumed in large quantities: it suffices to observe children during the holidays of end of year!

Eat for better sleep

Dinner for sleep
Contrary to what the adage says “who sleeps dines,” it is better to sleep BEFORE dinner! By sunset fasting, one may be awakened by stomach cramps, or cravings. Experiments in animals have shown that fasting can completely eliminate sleep. And we know that pregnant women and the elderly, it can cause severe discomfort (fall, loss of consciousness) related to hypoglycemia. Continue reading “Eat for better sleep”

Five rules for good sleep

Frequent awakenings, difficulty falling asleep, your sleep is disrupted? However, a few simple rules can help you find the sleep you crave.

Here are five tips that should help you not to become insomniac …

good sleep

1 – Respect your sleep
You have trouble falling asleep at night? May simply miss you your sleep time, because you really want to see the end of the film, finish your book or because you’re with friends. As sleep is organized in cycles of about half past one, if you miss your “train”, you should wait for the next. You may therefore turn and you return to your bed without being able to hang up the car! Similarly, if you are in the evening, needless to bed early, you will not be able to fall asleep! When your eyes sting, you yawn and shiver … It’s time, spin! Then try, whenever possible, go to bed and get up every day at approximately the same time. If you abuse the sleep (sleep 11 hours on weekdays, 4 am on Saturday, up 14 h, etc.)., It will be increasingly difficult. Continue reading “Five rules for good sleep”
