Abstract: The multidisciplinary Institutional Committee of experts in Systemic Arterial Hypertension from the National Institute of Cardiology "Ignacio Chávez" presents its update (2008) of "Guidelines and Recommendations" for the early detection, control, treatment and prevention of Hypertension. The boarding tries to be simple and realistic for all that physicians whom have to face the hypertensive population in their clinical practice. The information is based in the most recent scientific evidence. These guides are principally directed to hypertensive population of emergent countries like Mexico. It is emphasized preventive health measures, the importance of the no pharmacological actions, such as good nutrition, exercise and changes in life style, (which ideally it must begin from very early ages). "We suggest that the changes in the style of life must be vigorous, continuous and systematized, with a real reinforcing by part of all the organisms related to the health education for all population (federal and private social organisms). It is the most important way to confront and prevent this pandemic of chronic diseases". In this new edition the authors amplifies the information and importance on the matter. The preventive cardiology must contribute in multidisciplinary entailment. Based mainly on national data and the international scientific publications, we developed our own system of classification and risk stratification for the carrying people with hypertension, Called HTM (Arterial Hypertension in Mexico) index. Its principal of purpose this index is to keep in mind that the current approach of hypertension must be always multidisciplinary. The institutional committee of experts reviewed with rigorous methodology under the principles of the evidence-based medicine, both, national and international medical literature, with the purpose of adapting the concepts and guidelines for a better control and treatment of hypertension in Mexico. This work group recognizes that hypertension is not an isolated disease; therefore its approach must be in the context of the prevalence and interaction with other cardiovascular risk factors such as obesity, diabetes, dislipidemia and smoking among others. The urgent necessity is emphasized to approach in a concatenated form the diverse cardiovascular risk factors, since independently of which they share common pathophysiological mechanisms, its suitable identification and control will affect without any doubt the natural history of the other concatenated risk factor. By all means that to greater participation of factors, greater it will be the global cardiovascular risk but never, however, the specific weight is due to avoid that each one has on the global cardiovascular risk. In this Second edition we try to amplify and give systematic forms for the clinical approach for the suspicion of secondary hypertension and we emphasizes that hypertension in the woman with or without menopause should be careful analyzed, and special recommendations are given for the hypertension in pregnancy. Also we have approached some aspects related to the hypertensive emergencies and other special situations. In this second version some recommendations are presented for boarding hypertension in children and adolescents.

Abstract: The cardiovascular disease is a crucial cause of morbidity and mortality in the woman mainly when they arrive at menopause. The pathophysiology and neurohormonal mechanisms widely vary with respect to the man. This finding has given the support to think that the estrogens may be playing a protector role in cardiovascular disease. However, the associated risk factors like obesity, diabetes, dislipidemia, smoking and sedentary life are increasing in an exponential form. In Mexico the population age distribution establishes that 60% of the women with hypertension are aged < 54 years old. This is reason why as factor of independent cardiovascular risk is commonest. Nevertheless, after the menopause cardiovascular mortality is greater in the woman than in the man. In this review, the importance of the new pathophysiological mechanisms and the clinical-therapeutic approach are analyzed, making emphasis in the importance of the change in the life style and also in the nutritional aspects. In Mexico the woman still have a unique role in the nutritional culture.

Abstract: AIMS: Hypertension remains as a major cause of cardiovascular morbidity in México. The Health National Survey 2000 of México was performed to analyze the current status of the prevalence of some risk factors such as diabetes, hypertension (HTA), obesity, smoking, and proteinuria. METHODS: A National Survey was carried out in México where 45,300 individuals between 20 to 69-y.o. were screened. The estimated sample size was calculated considering the total number of persons into the mentioned age; a minimal prevalence of 6% of the included risk factors, at a significance level of 0.05; a maximum relative error of 0.145, and a rate of response of at least 70%. Diagnosis of HTA was accepted in: previous medical diagnosis with prescription of antihypertensive drugs, or high blood pressure (> or = 140/90 mmHg) detected during the interview. Data were adjusted for the national distribution of age-groups and gender (established in 2000, INEGI). RESULTS: 38,377 (98.8%) individuals were correctly screened for blood pressure. The prevalence of hypertension in México was 30.05% (34.2% in men and 26.3% in women). The prevalence was directly related with age and gender. The percentage of mexicans with HTA after 50-y.o. is > 50%. The prevalence was greater in women after 50-y.o. Among persons with hypertension, treatment was detected in 46% and approximately 20% of them were controlled (< 140/90 mmHg). The percentage of mexicans with HTA who were unaware that they have high blood pressure was 61%. The total percentage of HTA controlled was 14.6%. The North states had the greater prevalence (approximately 34%) of HTA while South states had the lower prevalence (27%). The odds ratio (age/sex-adjusted) for HTA were: for diabetes 1.54(CI95%, 1.44-1.63); for obesity 2.3 (CI 95%, 2.22-2.43); for smoking 1.26 (CI 95%, 1.21-1.32). For proteinuria subjects, 40% had HTA. CONCLUSIONS: Around 15 millions of mexicans between 20 to 69-y.o. had hypertension, 60% of them are unaware. The prevalence of hypertension in México (30.05%) has increased. Among persons with hypertension -15% are controlled. The North of México has the higher prevalence of hypertension. Diabetes, smoking, and obesity increase the risk of hypertension. The 2000 National Survey of Health shows the epidemiological trend in several important chronic diseases in México and declare an urgent need of new strategies for detection, control and treatment of hypertension.

Abstract: Increasing evidence indicates that hypertension in pregnancy is an under recognized risk factor for cardiovascular disease (CVD). Compared with women who have had normotensive pregnancies, those who are hypertensive during pregnancy are at greater risk of cardiovascular and cerebrovascular events and have a less favorable overall risk profile for CVD years after the affected pregnancies. One factor that might underlie this relationship is that hypertensive disorders of pregnancy (pre-eclampsia, in particular) and CVD share several common risk factors (e.g. obesity, diabetes mellitus and renal disease). Alternatively, hypertension in pregnancy could induce long-term metabolic and vascular abnormalities that might increase the overall risk of CVD later in life. In both cases, evidence regarding risk-reduction interventions specific to women who have had hypertensive pregnancies is lacking. While awaiting results of large-scale studies, hypertensive disorders of pregnancy should be screened for during assessment of a woman's overall risk profile for CVD. Women at high risk must be monitored closely for conventional risk factors that are common to both CVD and hypertensive disorders of pregnancy and treated according to current evidence-based national guidelines.

Abstract: The epidemic of childhood obesity, the risk of developing left ventricular hypertrophy, and evidence of the early development of atherosclerosis in children would make the detection of and intervention in childhood hypertension important to reduce long-term health risks; however, supporting data are lacking. Secondary hypertension is more common in preadolescent children, with most cases caused by renal disease. Primary or essential hypertension is more common in adolescents and has multiple risk factors, including obesity and a family history of hypertension. Evaluation involves a through history and physical examination, laboratory tests, and specialized studies. Management is multifaceted. Nonpharmacologic treatments include weight reduction, exercise, and dietary modifications. Although the evidence of first line therapy for hypertension is still controversial, the recommendations for pharmacologic treatment are based on symptomatic hypertension, evidence of end-organ damage, stage 2 of hypertension, or stage 1 of hypertension unresponsive to lifestyle modifications, and hypertension with diabetes mellitus.

Abstract: BACKGROUND: A number of cross-sectional or serial studies have demonstrated the clinical impact of microproteinuria and macroproteinuria by identifying individuals at risk of both end-stage renal disease and major cardiovascular events. This study focused on the prevalence of proteinuria in Mexico and its relationship with other cardiovascular risk factors such as hypertension, type 2 diabetes mellitus, body mass index, smoking, age, and gender. METHODS: The prevalence of proteinuria in Mexico was obtained from the probabilistic cross-sectional national health survey performed in the year 2000. The proportion of urine dipstick samples that tested positive for protein (defined as > or =1+) in adults from 20 to 69 years of age was determined. The analysis was performed using both algebraic and multicategorical models. Potential interactions between proteinuria and other major cardiovascular risk factors were investigated. RESULTS: A total of 46,523 adult survey participants were included in the analysis. In the general population, 9.2% had proteinuria. By univariate, multivariate, and multicategorical analysis, hypertension, diabetes, obesity, and age were strongly associated with the prevalence of proteinuria (P < 0.001). However, in Mexico, the specific distribution of age groups demonstrated that the absolute number of patients without hypertension that had proteinuria is not irrelevant. To identify 1 case of proteinuria, one would need to screen 3 persons with diabetes mellitus, 5 patients with hypertension without diabetes, or 6 persons over the age of 55 years. When proteinuria is present, the probability of having a noncommunicable chronic disease or other major cardiovascular risk factor is more than 85%. CONCLUSION: Proteinuria is prevalent. When considered together, dipstick-positive proteinuria, blood pressure level, body mass index > or =30 m(2)/kg, and abnormal fasting blood glucose measured on a single occasion identifies different segments of the population. Studies such as this may be a suitable initial clinical approach to general population screening for renal and cardiovascular risk stratification.

Abstract: OBJECTIVE: Based on a National Re-survey on Hypertension (HTA) and other cardiovascular risk factors performed in Mexico during 2003 and 2004 in the adult population with HTA, as identified in the 2000 National Survey of Health, this study was planed to determine: 1) morbidity and mortality rates; 2) the incidence and interrelation with other risk factors, such as overweight, obesity, dyslipidemia, nephropathy and diabetes; 3) the main risk factors associated to HTA involved in its complications, need for hospitalization and number of days; and, 4) the degree of therapeutical adhesion and the type of antihypertensive drugs used. METHODS: The survey was of type III using the step by step method described by WHO. Sampling was weighed a priori taking into account a national prevalence average of HTA of 30.05% and its corresponding rate for each federal state. Permissible maximum error in the estimation = 0.28. Effect of design = 4.5; and, Rate of awaited answer (0.70). RESULTS: From the initial 14,567 interviewed patients, 1,165 (8%) subjects were considered non-hypertensive or false positives at the 2000 survey. From the 13,402 remaining patients, 335 died during the first 2 years of pursuit, which implies an annual mortality of approximately 1.15% in the hypertensive population. Thus, 13,067 survivors were subjected to the final analysis. The mean age at the re-survey was 45.6 +/- 12.6; 40.5% were men (n = 5,295). There was a statistically significant difference in height, but not in weight between both genders. The control HTA was raised 14.6% in the year 2000 and 19.2% in 2004. The prevalence of diabetes was duplicated from 16% to 30% (< .001). Fifty four percent of the whole population required hospitalization at least once during the period of study. The rates of overweight, obesity, and dyslipidemia rose significantly (p < 0.05) independently from age, federal state, and gender. CONCLUSION: RENAHTA shows the impact of hypertension on the morbidity and mortality during the 3.1 +/- 1.5 years of follow-up in Mexico. It alerts us on the need to reinforce the strategies of attention and prevention of this crucial risk factor and of screening the dynamic nonlinear interaction between the main cardiovascular risk factors in Mexico. New hypotheses are proposed for the metabolic syndrome.

Abstract: AIMS: To know the prevalence and the interaction among the principal cardiovascular risk factors such as hypercholesterolemia (HCL), hypertension (HTA), overweight, carbohydrates metabolism disturbances, and smoking, an urban survey was performed in the six Mexican Republic states, where the national population is more concentrated. METHODS: This survey was transversally designed using the WHO type-III model in 120,005 adults from 6 highly populated urban centers (Mexico City, Guadalajara, León, Puebla, Monterrey andTijuana) were included. A blood sample from each person was obtained to quantify fasting glucose and cholesterol. Blood pressure, height and weight were measured using daily validated systems. Data were analyzed by a multicategorical conjunctive consolidation model and by multiple regression models. RESULTS: HCL global prevalence showed to be 43.3% for a population with an average age of 44.1 years. Female gender showed a slightly but statistically significant greater prevalence of HCL than male gender (44% vs 42.2%). From whole women population 33.2% declared to be in menopause, and 59.7% of them had HCL. In addition, HCL was directly related to body mass index (BMI). Thus, in those subjects with BMI < 25 showed a HCL prevalence 34.1%; while those with BMI was between 25 and 29.9, the HCL prevalence was 45.9%, and in those subjects with BMI > or = 30 Kg/m2, ranked a HCL prevalence of 47.3%. The prevalence of hypertension was 30.2% and 52.5% of them had HCL prevalence. Type-2 diabetes mellitus prevalence (DM-2) was 10.7%, 55.2% of them had HCL. In the group aged between 20 to 34 years old, the obesity was the principal determinant for higher HCL prevalence. The HCL prevalence showed to be quite similar in population with and without smoking. In conclusion, HCL prevalence shows 4 progressively increasing gradients associated with age, HTA, DM-2 and BMI.

Abstract: PURPOSE: To determine the prevalence and interrelation of noncommunicable chronic diseases (NCCD), obesity, smoking, and proteinuria in the adult population (between 20 and 69 years of age) of Mexico, and their stratification according to age, gender, and geographical area. METHOD: During the year 2000, a probabilistic national survey was performed in 45,300 persons. The sample size was calculated to approach NCCD with a minimal estimated prevalence of 6%. The survey corresponds to type III of the step-by-step method described by WHO. Data were weighted for the distribution of the population and gender, according to the national survey of population and housing (National Institute of Statistics and Geography, INEGI). RESULTS: A total of 38,377 (98.8%) of individuals were included in the analysis; 69.4% were women. Average age for men was 39.4 +/- 12.9 and for women 38.6 +/- 13.0. National average prevalence for hypertension was 30.05%, for diabetes of 10.7%, for obesity of 24.4%, for abnormal capillary glucose of 12.7%, and for proteinuria of 9.2%. Prevalence for hypertension and diabetes were directly related with age, body mass index, and waist perimeter. The pyramidal distribution of the Mexican population determined that the greatest proportion of prevalence of NCCD was given by those under 54 years of age with a statistical significance (> 75%). CONCLUSION: ENSA 2000 demonstrates the marked increase in NCCD prevalence in the Mexican population and alerts on the urgent need of national strategies to restrain this important public health problem. Strategies must be oriented towards an integrated approach of the NCCD, since their clinical and physiopathological interrelation is clearly demonstrated through ENSA 2000.
