[Prevalence and determinants of hypertension in Lomé (Togo): results of a screening in May 2011]. / Prévalence de l'hypertension artérielle et description de ses facteurs de risque à Lomé (Togo) : résultats d'un dépistage réalisé dans la population générale en mai 2011.

BACKGROUND: The prevalence of hypertension in the Sub-Saharan Africa region is increasing as a manifestation of the epidemiological transition, and this fact will oblige these countries to mobilize significant resources. World Bank estimates cheaper to prevent cardiovascular disease than to treat people once these diseases are established suggesting the need to know the prevalence of hypertension in order to allow prevention programs in our population. However, data in Togolese populations are rare. The purpose of the present study was to determine the prevalence of high blood pressure and its risk factors in Lomé. METHODS: We performed a cross-sectional survey among 2002 unselected respondents of the municipality of Lomé in May 2011. A questionnaire has been filled about family history of hypertension, habits and practices that affect hypertension on behalf of each respondent and anthropometric data and blood pressure has been measured. RESULTS: The prevalence of high blood pressure was 36.7% (34.6% of male vs. 38.4% of female, OR=0.85; 95%CI=0.7-1.02; P=0.08); 42.4% of the hypertensive respondents have been diagnosed at the screening. Blood pressure was positively correlated to the age (SBP: r=+0.46; P=0.001; DBP: r=+0.36; P<0.001), the body mass index (SBP: r=+0.7; P<0.001; DBP: r=+0.89; P<0.001) and waist circumference (SBP: r=+0.28; P<0.001; DBP: r=+0.3; P<0.001). There was a significant relationship between arterial hypertension and obesity (OR=1.65; 95%CI=1.47-1.84; P=0.003), salt consumption (OR=1.4; 95%CI=1.13-1.72; P<0.001) and oral contraception (OR=2.1; 95%CI=1.29-3.43; P=0.002). CONCLUSION: There was a high prevalence and low awareness of arterial hypertension in the municipality of Lomé with a female prevalence. This affection was correlated to age, salt consumption and obesity. This study raises the need for accentuating the prevention in our poor populations which are unable to face adverse outcomes which can occur.

[Compliance to treatment in heart failure patients in Lomé]. / Observance thérapeutique de l'insuffisant cardiaque à Lomé

BACKGROUND: The incidence and prevalence rates of the heart failure in the world approach epidemic proportions. The evaluation of the follow-up of the treatment of heart failure can allow the setting up of strategies to reduce the frequency of decompensations and improve the quality of life of these patients. OBJECTIVES: To estimate the compliance to treatment and factors liable to influence it in Togolese patients suffering from heart failure. PATIENTS AND METHODS: This study was carried out from January 1st, 2008 to June 30th, 2009 in the department of cardiology of the university teaching hospital Campus in Lomé and included prospectively, patients with chronic heart failure hospitalized for acute decompensation and of which the heart failure was diagnosed and treated for at least 3 months. Questionnaires were filled to estimate the compliance to medication, to diet, as well as knowledge of the patients on their disease and their relationship with their doctor and their family. RESULTS: In the 103 patients included, we noticed no good compliance to medication; there were 74.7% of bad compliance to medication, 47.3% of good compliance to diet; 62.1% of patients had enough knowledge on their disease, 29.1% considered that their doctor did not grant them enough time; 57.3% estimated to have no necessary support of their family. Bad compliance to treatment was correlated to the existence or not of a health care insurance (OR=115.5; 95% CI=21.51-620.08; P<0.0001); this difference persisted after adjusting for age, sex and monthly income (OR=99.65; 95% CI=18.87-587.21; P=0.001). Bad compliance was not associated with monthly income (OR=0.93; 95% CI=0.37-2.28; P=0.944); it was neither influenced by traditional therapy (OR=1.58 95% CI=0.64-3.91; P=0.43), nor recovery prayers (OR=1.6; 95% CI=0.62-4.13; P=0.45), nor frequency of tablets intake (≥3 intake day), OR=0.169; 95% CI=0.05-0.49; P=0.43. CONCLUSION: The compliance to medication in Togolese heart failure patients was very low and essentially correlated to the absence of health care insurance.

[Evolution of cardiovascular diseases' admissions in cardiology departments of Lomé hospitals: a cross-sectional study on 7959 patients from June 2004 to May 2009]. / Évolution des admissions pour maladies cardiovasculaires en milieu cardiologique à Lomé : étude transversale de 7959 patients de juin 2004 à mai 2009.

BACKGROUND: To determine the frequency of cardiovascular diseases, their risk factors as well as their evolution in two cardiology departments of Lomé. METHODS: This cross-sectional study was carried out among patients attending two cardiology departments of Lomé, from June 2004 to May 2009, who had a diagnosis of cardiovascular disease. RESULTS: A total of 7959 patients were included. Female gender predominated. The mean age was of 49.5 ± 17.2 years. The number of admissions increased from 958 in 2004 to 2399 in 2009. Arterial hypertension (62.7%) and ischemic heart diseases (10.6%) were the most frequent diagnoses. Among patients with a diagnosis of heart failure, the etiology was not recorded for 12.2%. Overweight and dyslipidemia were significantly more frequent in women (P<0.001), while smoking and physical inactivity were significantly more frequent in men (P<0.001). During the period, there was a moderate rise of the prevalence of overweight, dyslipidemia, and physical inactivity, whereas the prevalence of diabetes and smoking remained almost unchanged. CONCLUSION: Admissions for cardiovascular diseases increased from 2004 to 2009. This epidemiological transition may be related to poor awareness of cardiovascular disease among the low-income population and the financial burden of health care.

[Arterial hypertension in black subjects over 50 years of age in Lomé: epidemiological aspects and evaluation of cardiovascular risk (prospective and longitudinal study of 1485 patients)]. / Hypertension artérielle du sujet noir âgé de 50 ans et plus a Lomé : aspects épidémiologiques et évaluation du risque cardiovasculaire (Étude prospective et longitudinale de 1485 patients).

INTRODUCTION: High blood pressure is a public health problem for which the assumption of responsibility remains especially difficult in older subjects. Generally, it is associated with other cardiovascular risk factors. The objective of this study is to determine the prevalence of high blood pressure in older subjects in a particular environment and to evaluate the cardiovascular risk among these patients. METHODOLOGY: This is a longitudinal exploratory study undertaken on 1485 hypertensive subjects of 50 years of age or older, selected from 1999 patients received in three health professional training centers of the community of Lomé, between June 1, 2004 and June 30, 2007. Information had been collected using a card of investigation. Classifications of high blood pressure were those of the JVCVII and the European Society of Cardiology. The data analysis had been made by computer tools. RESULTS: The prevalence high blood pressure was of 74.29%. We had noted a female prevalence (63.8%) with a sex ratio of 0,57 and one middle age of 62.08±9.3 years. Dyspnea (45.9%), chest pains (16.2%) and palpitations (13.2%) were the principal found symptoms. The various listed risk factors were: dyslipidemia (58.1%), obesity (36.12%), alcoholism (16.7%) and diabetes (10.6%). The complications were cardiac (87.81%), ocular (79.8%), renal (19.86%), neurological (4.92%) and arterial (0.99%). The cardiovascular risk was very high at 58.05% of the patients. The mortality rate was of 1.9%. CONCLUSION: High blood pressure is the most frequent cardiovascular risk factor in our country from 50 years of age. Assumption of responsibility for it is by information, education of the population and requires the mobilization of all the social components.
