The objectives of this study were to determine post-infarction drug therapy at discharge from hospital and at one year in the Basse Normandie region (France) and the management of risk factors, to compare them with the practice recommended by the French Society of Cardiology and other recent references. Patients whose medical expenses were exonerated by the Social Security for primary myocardial infarction without a history of angioplasty or of coronary bypass grafting between February and September 2002 were reviewed. The data was researched from the hospital, the patient, the attending physician and the data bases of the Social Security. Four hundred and fifteen patients were included. At discharge from hospital the percentages of prescriptions of recommended drugs were as follows: betablockers 85%, antithrombotics 99%, ACE inhibitors 75%, lipid lowering drugs 90%; the four drug families were associated in 63% of cases. There was no significant difference in prescription between hospital discharge and the twelfth months except with regards to ACE inhibitors (68%) and the association of the four drug groups (54%). The prevalence of smoking, hypertension, diabetes, overweight, obesity and dyslipidaemia were respectively 40, 39, 9, 44, 20 and 81% at the time of infarction. At one year, the prevalence of smoking had fallen significantly to 16%; only 10.3% of patients had uncontrolled hypertension and only 29% had not obtained the recommended therapeutic target for LDL-cholesterol. The authors conclude that this analysis shows an adequation of drug prescription to current recommendations and an improvement in risk factor management which should, however, be pursued.

Although the year 2005 has reinforced the therapeutic advances of 2004, with confirmation of certain concepts, the 'coxib affair' has continued to provoke arguments between pharmaceutical companies, licensing agencies as well as patients, some of whom have amalgamated into consumer groups to reject en masse placing any responsibility on the prescribers in favour of an attack on the drug licensing process itself. Among the cardiovascular drugs that will soon be licensed, only ivabradine in stable angina, and remodulin in primary pulmonary arterial hypertension are new. The therapeutic advances in 2005 regarding platelet aggregation and blood coagulation have been significant, in the human, scientific and commercial context, while hypertension has not been ignored. Another new development is the ever more precise notion of the metabolic syndrome, a target of choice for the pharmaceutical industry. The potential range of applications has been widened to include obesity, hypertension, diabetes, HDL cholesterol... The licensing authorities find themselves facing a hurdle to overcome, with novel combinations of drugs (ACE inhibitors, calcium blockers/statins, statins/aspirin, ARA2/calcium blockers...).

Our simple definition of ethics is good thought, speak and action. Epistemology means the hypothesis of facts about thought, speech and action. Medical practice is all means of medicine. Medicine classifies people into normal and abnormal. The abnormal are the sick. They loose some organs or those normal looking organs are dysfunctional. They are social problems, some can be treated, and some do not get the appropriate care. The problems of society of normal people are overeating and obesity, abortion, drug abuse, promiscuity, torture, terrorism, disobeying rules and order, corruption, brain-washing and unethical advertisements, etc. On the other hand, the social problems of the abnormal are down, deafness, blindness, dumb, hypertension, hypercholesterolemia, diabetes mellitus and cancer, etc. An example of the social-doctor problem is the mal distribution of doctors in rural areas. It was reported by the ministry of public health that the ratio of doctor to population to be 1:800 in Bangkok and 1:5, 700 in some rural areas in the north eastern part of Thailand. The doctors, themselves, are at a high grade of worker and intelligent quotient. They know all the problem and, at the same time, create problems, both, faster than the general population can do. It affects good and bad in the society. In the past, present and the foreseeable future the medical students get their studies in the western style. Their medical schools are situated in big cities. These schools are old and famous. They learn their medical procedure in a big hospital of more than 400 beds in the inpatient department wards. Their instructors and professors are highly qualified, are middle class people and well accepted in the society. Their families are lovely and warm. Their children study in the first class schools in town. The medical students feel very happy and appreciate seeing their professors in television routinely at prime time. In conclusion, their professors are an example of role model for them to follow. Everyone looks for security in her/his profession. Facts need no proof and reference. People with justice in mind should believe and understand the above mentioned. This leads to the problem of mal distribution of doctors in rural areas, why do doctors live in big cities or wish to be in the private sector? In fact, not many a number of doctors serve in the rural area. About 4-5 of them, their name will be announced yearly as the best rural doctor award. After the big ceremony, lasted not longer than a month, it is hard to remember their name. They are proud to be praised, it pushes them into stress intentionally with all the best of their intelligence and the total of their body strength to work harder in rural. Unfortunately their earning, the security of their profession, the increased chance of being sued, to get caught in the medical litigation, the expenses of their family social status and the study of their children cannot be compared to of those doctors in big city and/or in the private sector. Mal distribution of doctors in remote rural areas has been a persisting unresolved problem in many parts of the world, why not apply the principles of ethics and epistemology? They have been left, untouched forever.

Cell biology is in transition from reductionism, to a more integrated science which is now preoccupied by molecular interactions acting in modules. Large-scale quantitative analysis of gene expression, including cDNA microarrays and proteomic analysis, is now applied to heart failure and atherosclerosis. The technology is still at the beginning and is limited by variations in the array platforms and gene products as well as sensitivity or specificity of the selected probes. These limitations are progressively going to be reduced, but still they do exist. Biological systems are scale free networks made from genes, proteins or traits that interact one another and form networks and functional modules. Networks emerge through the addition of new nodes which are preferentially attached to more connected nodes to form hubs, according to the "rich-gets-richer" mechanism, and there are large networks which include central genes (nexus). Both hubs and nexus are attractive candidate for targeting new therapy. An important study from King JY et al. (Physiol Genomics 2005; 23: 103-18) exemplifies this concept by showing the first realistic pathways to understand atherosclerosis. The 4 steps of the design are based on histological grading and microarrays analysis and include an association network constructed from PubMed and the construction of sub-networks in which genes whose expression was differentially regulated were indicated. Connectivity analysis networks revealed new important modular pathways. In heart failure, no attempts have been made to organize the data into functional modulus. Since the causes of heart failure are well documented, the problem is to identify functional modules responsible for myocardial dysfunction. Several potential functional modules can be identified so far. Indeed, cardiac remodeling results from two types of changes in gene expression, namelly the reexpression of the foetal programme which has a mechanical origin and several well documented interfering determinants that modified the basic remodelling, including senescence, obesity, diabetes, ischemia, and the neurohormonal reaction.

Obesity and insulin resistance are directly associated with the presence of microalbuminuria. However, the prospective relationship between abdominal adiposity and the occurrence of micro-albuminuria has been little studied in a non-diabetic population. From the DESIR cohort, we examined whether waist circumference was associated with the incidence of micro-albuminuria at 6 years (D6). The study evaluated 2738 non-diabetic subjects without micro-albuminuria at inclusion who were then followed prospectively. At 6 years, 254 individuals (9.3%) had developed pathological micro-albuminuria (> or =20 mg/l) measured at micturation. In both sexes, the incidence of micro-albuminuria was associated with increased waist circumference and blood pressure, but not with blood glucose levels, lipid parameters or body mass index. Subjects with a higher waist circumference at inclusion were at a higher risk of having micro-albuminuria at 6 years compared to those with a normal waist circumference. Logical regression analysis showed that waist circumference as a continuous value, or greater than 94 cm for males and 88 cm for females, were predictive factors for the incidence of micro-albuminuria, after adjustment for age, hypertension, ACE inhibitor usage, fibrinogen, and blood glucose level. Abdominal adiposity is thus linked in both sexes to the development of microalbuminuria, which underlines the importance of measuring waist circumference when assessing risk factors for renal lesions in non-diabetic hypertensives.

Metabolic syndrome is public health problem. The characteristic feature is an association between factors contributing to increased cardiovascular risk. Several definitions have been proposed from 1998 to 2005. All proposed definitions take into consideration insulin resistance and its corollary hyperglycemia, overweight, hypertriglyceridemia, and LDL-cholesterol lowering. The most widely used definitions are proposed by the World Health Organization (WHO) and the American "Cholesterol" program (NCEP-ATpIII). The prevalence of metabolic syndrome varies by geographic region as a function of the chosen definition, the study methodology, the selection criteria, the age and gender of the study population, and the period of the study. Prevalence is higher in the United States than Europe and increases with age. A growing number of adolescents appear to meet the criteria of metabolic syndrome. Irrespective of the definition retained, metabolic syndrome is associated with increased cardiovascular risk and increased risk of type II diabetes. Sound evidence is however lacking on whether the risk is greater than that of taking into account each individual factor. Several points remain to be clarified concerning the underlying mechanisms. Visceral adipose tissue appears to be a key element in the process via anomalous function related to obesity and insulin resistance. Management is based mainly on reduction of body weight and regular physical activity. Drugs may be necessary to correct for the dyslipidemia, normalize blood glucose and reduce blood pressure.

The recent analysis of the French MONICA registries report a reduction in the incidence of fatal MI related to improvement of care whereas the overall incidence of coronary events remain stable, suggesting the need for a better primary prevention. The extensive review of the death certificates and the analysis of the death classification from the same registries indicate an under estimation of MI-related death in the national death registry. It is also confirmed that instead of 50%, approximately 80% of coronary death are explained by the four major risk factors including smoking, hypercholesterolemia, hypertension and diabetes. The international REACH registry has enrolled more than 67 000 individuals including patients with symptomatic atherothrombotic disease and patients with multiple risk factors. The analysis of baseline characteristics and of the one year FU shows a high residual risk and a lack of efficacy of secondary prevention. The existence of a symptomatic disease and the number of symptomatic localization of atherothrombosis are critical factors to predict recurrence of major vascular events Secondary analysis of the INTERHEART study provide the essence of what should any physician know about the relationship between coronary heart disease and smoking, either active or passive. Prevention with respect to this risk factor remains very insufficient. Varenicline, a new nicotinic receptor partial agonist, should help patients involved in smoking cessation program. The established detrimental effects of perioperative smoking represent a unique opportunity to promote smoking cessation in individuals scheduled for surgery. The major cardiovascular impact of second hand smoking has been recently demonstrated by the short-term effects of banning smoking in public places on the incidence of acute coronary events. The SPARCL study has demonstrated the benefit of high dose of atorvastatine to prevent recurrent acute ischemic cerebrovascular event in patients with a prior history of stroke or TIA. In the open ASTEROID study, high doses of rosuvastatine confirm the possibility of reducing the volume of coronary atheroma analyzed by IVUS. The expected benefit of glitazones to reduce the incidence of death, MI and stroke in diabetes patients with a prior history of vascular event has been confirmed in the PROactive study. Pioglitazone provided a clear reduction of recurrent vascular events in diabetes patient with a prior MI at a cost of a significant increase of the risk of heart failure. In the DREAM study, neither ramipril nor rosiglitazone have reduced the incidence of cardiovascular events significantly. The moderate benefit of the fenofibrate to prevent cardiovascular events in the FIELD study, which was carried out in diabetics mostly in primary prevention, needs to be considered after adjustment on statin use in a higher proportion of patients of the placebo group. Postprandial hyperglycaemia, analyzed by the peak of glycaemia after a load in glucose, has been confirmed as a more powerful independent predictive factor of the risk of cardiovascular event than fasting glycaemia. The systematic screening postprandial hyperglycaemia represents an interesting strategy for primary prevention which warrants further investigation. If obesity is a risk factor whose impact on morbi-mortality is well established, a French study shows that body mass index has an unfavourable influence on the cognitive functions in middle-aged men and women.

During these 10 last years, even though patients had a more and more severe condition, the results of coronary artery bypass surgery have continuously improved. According to Society of Thoracic Surgeons data, the operative risk increased by 1/3 (2.6% in 1990 vs. 3.4% in 1999), whereas the per-operative mortality was reduced by 1/4 (3.9% in 1990 vs. 3% in 1999), and is currently stabilized around 2.5-3%. The incidence of complications is a non-negligible marker. The complications observed are mostly neurological (2%), renal (4%), myocardial (4%), infectious (0.5 to 2%), and respiratory (10%). Their occurrence is related to the presence of preoperative risk factors: age (>60 years), sex (female), EF <50%, diabetes, severe obesity, lung disease, renal failure, recent myocardial infarction, redo and/or emergency surgery... The detection and peri-operative control of these factors permit a reduction of complications incidence and limit the length of stay; a better management of per-operative blood glucose in diabetic patients reduced significantly the morbidity. These factors are used in different scores, such as the Euroscore, which seems to be the best predictor of mortality. Patients stratification according to their risk profile permits to inform the patient and his/her family regarding the operative risk and take peri-operative therapeutic decisions, in order to reduce the morbidity and mortality during coronary artery bypass surgery.

Obesity and asthma are both public health problems that have been increasing for several years. This increase suggests that there may be a connection between these two pathologies. The aim of this study was to examine the relationship between obesity and asthma by measuring the prevalence of obesity in asthmatic children compared with a control population, by analysing the impact of obesity on the severity of the asthma, and by examining the relationship between obesity and atopy. The study was based on 100 children aged from 4 to 16 years in whom the diagnosis of asthma was confirmed; obesity being defined as a body mass index greater than the 97th percentile. The prevalence of obesity in these patients was 14%. Obesity was not a factor in the severity of the asthma as 14.5% of the severe asthmatics were obese compared with 18.75% of the mild and moderate asthmatics. 13% of the atopic subjects were obese compared with 13% of the non-atopics. Obesity does not constitute, therefore, a risk factor for asthma and does not contribute to the severity of the disease. In addition there is no relationship between obesity and atopy.

Despite a variable prevalence in the literature, OSAS is characterized by a higher frequency in men. This study involved a review of published data describing the impact of gender on features of OSAS. In women, OSAS seems to be associated with certain anatomical factors such as more significant obesity, a thinner oropharyngeal junction, a shorter uvula and reduced upper airway (UA) collapsibility, in comparison with men. Sleep related breathing disorders observed during pregnancy are more likely UA resistance syndrome than true OSAS, and are associated with severe fetal and maternal complications that could be improved by the use of nasal CPAP. Though OSAS symptoms are underestimated by women, the Epworth score as well as snoring are not influenced by gender. Gender does not seem to be a risk factor for increased mortality. Compliance with nasal CPAP is identical in both sexes, but oral appliance seem to be more effective in women. Further studies are needed to produce the required complementary data to confirm specific sex-related features in the diagnosis and treatment of OSAS.
