RESUMO

BACKGROUND: Cardiovascular disease (CVD)-related admissions are on the increase in Nigeria and the rest of Africa. This study was carried out to highlight the burden, patterns and outcomes of CVD admissions in a tertiary hospital over a 16-year period in Lagos, Nigeria. METHODS: Admissions records of patients admitted into the medical wards within the study period (January 2002 to December 2017) were reviewed and relevant information pertaining to the study objectives was retrieved for analysis. RESULTS: There were a total of 21 369 medical admissions and 4 456 (20.8%) CVD-related admissions. A total of 3 582 medical deaths were recorded and 1 090 (30.4%) CVD-related deaths. The median age of the patients was 56.6 (46.0-68.0) years and 51.4% of these were males. Stroke, heart failure, hypertensive disease and acute coronary syndrome constituted 51.2, 36.2, 11.3 and 1.6% of all CVD admissions, respectively. There was a cumulative increase in the number of CVD admissions and deaths (p < 0.001, respectively) during the period under review. CONCLUSIONS: CVD admissions are not only common in Nigeria, but there was also a temporal exponential increase in both the admission and death rates, most likely reflecting the epidemiological transition in Nigeria.

RESUMO

BACKGROUND: Sickle cell anemia is the commonest hemoglobinopathy in pregnant Nigerian women, and cardiac manifestations are a significant feature of the disease especially in pregnancy. Pregnant women with sickle cell anemia are at high risk of morbidity and mortality and cardiac dysfunction in them increases this risk and may compromise their post-partum health. OBJECTIVE: To evaluate the cardiac size and function in women with sickle cell anemia (HbSS) during late pregnancy and postpartum. METHODOLOGY: This was a longitudinal comparative study in which 40 women, consisting of 20 pregnant HBSS and 20 pregnant HBAA women controls, were recruited. Echocardiography was performed in the third trimester of pregnancy and 6 weeks postpartum. RESULTS: There was a decrease in the mean left atrial diameter (p < .001), left ventricular diameter in diastole (p = .041), and left ventricular mass (p = .004) of HBSS women in the postpartum period compared to their antepartum state. In contrast, there was no significant difference in most cardiac dimensions of pregnant vs postpartum HBAA women. There was no significant change in cardiac function in the pregnant vs postpartum states in both study groups. There were significant differences in cardiac size but not function when comparing HBSS and HBAA women in pregnancy and postpartum. CONCLUSION: Changes in cardiac size of sickle cell women in pregnancy does not appear to affect cardiac function during pregnancy and in the puerperium, suggesting that the increased size may purely be a response to their chronic anemic state. Studies following women up for longer periods including those with co-morbidities are recommended.

RESUMO

BACKGROUND: Simultaneous presence of elevated waist circumference and hypertriglyceridemia (HTGW) is a simple and low-cost measure of visceral obesity, and it is associated with a plethora of cardio-metabolic abnormalities that can increase the risk of cardiovascular diseases and incident Type 2 diabetes mellitus. We decided to study the prevalence, patterns, and predictors of metabolic abnormalities in Nigerian hypertensives with the HTGW phenotype. METHODS: The medical records of 582 hypertensives with complete data of interest were retrieved and analyzed for the study. Their socio-demographic data, anthropometric data, and booking blood pressure values were retrieved. The results of their fasting plasma glucose, lipid profile, uric acid and serum creatinine were also retrieved for analysis. RESULTS: The mean age of the study population was 56.2 ±13.6, with 53.1% being males. The prevalence of smoking and use of alcohol was 4.3% and 26.5% respectively. The prevalence of the HTGW phenotype was 23.4% and were predominantly males (61%). Subjects with the HTGW phenotype were more obese assessed by waist circumference (WC) and body mass index (BMI). Mean serum total cholesterol, triglyceride, very low-density lipoprotein, uric acid, and creatinine were significantly higher in the HTGW phenotype (p = 0.003; <0.001; <0.001; 0.002 and <0.001 respectively). The prevalence of newly diagnosed Type 2 diabetes was 28.7%. There was also a preponderance of cardio-metabolic abnormalities (obesity, dyslipidaemia, hyperuricemia) in the HTGW phenotype. In both males and females, the HGTW phenotype was significantly associated with elevated Tc, TG, VLDL, hyperuricemia and atherogenic index of plasma. CONCLUSION: The HTGW phenotype is common amongst Nigerian hypertensives, and it is associated with metabolic abnormalities.

RESUMO

Hypertension is the most prevalent cardiovascular disorder in the world. It is associated with target-organ damage in various organs and ECG changes. P-wave dispersion (PWD), which represents inhomogeneous atrial conduction and discontinuation of impulses, has been observed, when prolonged, to predict atrial fibrillation, particularly in the setting of hypertension. This study of PWD in 150 hypertensive patients and controls sought to determine the prevalence of PWD in Nigerian hypertensives and its relationship to left ventricular mass index and left ventricular function. Mean PWD in normal subjects was 32.14 ± 4.72 ms and was significantly shorter than that in hypertensive patients at 38.29 ± 8.02 ms. In the total population, 51.3% had prolonged PWD ( > 33.46 ms); 70% in the hypertensives and 32.7% of controls. The only significant difference in hypertensives with prolonged and normal PWD was the waist circumference. There was a negative correlation between PWD and ejection fraction (r = -0.17, p = 0.03), but not with diastolic function.

RESUMO

Background Early identification and treatment of cardiovascular disease (CVD) risk factors through screening are crucial in the primary prevention of CVD and reduction in healthcare-related costs. Use of Non-Physician Healthcare-workers including Community Pharmacists has been advocated as an effective and cost-efficient model of healthcare delivery. In Nigeria the use of community pharmacists for mass screening of CVD risk factors has not been explored. Objective We sought to investigate the possibility of mass CVD risk factor screening in community pharmacies by pharmacists. Setting Lagos, Nigeria. Methods Between October and December 2018 eight hundred and eighty-nine apparently healthy participants were screened for obesity, hypertension, diabetes and hypercholesterolaemia in ten community pharmacies. Diabetes and hypercholesterolaemia were screened for using point-of-care testing modalities. A structured questionnaire was used to obtain the socio-demographic data of the participants. Main outcome measures Prevalence of overweight/obesity, hypertension, diabetes, hypercholesterolaemia, smoking and alcohol intake. Results Mean age of the subjects was 56.8 ± 21.1 years. Majority (57.4%) were females. Prevalence of smoking and alcohol intake were 4.3% and 26.7% respectively. 59.7% and 71.5% of males and females were either overweight (BMI ≥ 25 kg/m2) or obese (BMI ≥ 30 kg/m2) respectively. Prevalence of hypertension was 28.2% in all subjects, 30.9% in males and 26.3% in females, p < 0.001. Using BP > 130/80 mmHg prevalence of hypertension was 55.1%. Diabetes was detected in 3% of the subjects while 45.3% had hypercholesterolaemia. In total, 64.1% of the subjects were diagnosed with CVD risk factors for the first time. Conclusion Opportunistic screening for CVD risk factors is possible in community pharmacies and has the ability to detect previously undiagnosed risk factors. This community pharmacy based model could serve as a cost-effective approach to primary prevention of CVD.

RESUMO

Congenital heart disease (CHD) in low-and-middle income countries (LMIC) is often characterized by late presentation resulting from inadequate screening and healthcare access in these regions. Accurate estimates of the burden of CHD among school children are often lacking. The objective of this study was to determine the prevalence and distribution of CHD among school children in two communities (urban and semi-urban) in south western Nigeria. Using clinical assessment and portable echocardiography, 4107 school children aged 5 years to 16 years in Lagos, Nigeria, were selected using a multistage sampling procedure and screened for CHD. Diagnosis of CHD was made after echocardiography. Children identified with CHD were referred to a tertiary hospital for appropriate cardiac care. The 4,107 children screened had a mean age of 11.3 ± 2.7 years and 53.7% were females. Twenty seven children had echocardiography-confirmed CHD, representing a prevalence of CHD among school children in Lagos, Nigeria of 6.6 per 1000 children. Acyanotic CHD constituted 96.3% of detected cases. Two children diagnosed with CHD (Tetralogy of Fallot and severe pulmonary valve stenosis respectively) had successful intervention. The prevalence of previously undiagnosed CHD among school children in Lagos Nigeria is substantial and highlights gaps in the health care system and school health programs. Echocardiographic screening of school children provides an opportunity for missed early diagnosis and treatment of CHD and reduces the prevalence of first-diagnosed CHD in adulthood. Therefore, focused clinical examination of school children followed by echocardiography is a strategy that could bridge this diagnostic and treatment gap in CHD.

RESUMO

BACKGROUND: Professional drivers are known to be at high risk for cardiovascular disease (CVD) on account of the higher prevalence co-occurring risk factors they harbour. Chronic kidney disease (CKD) and CVD share similar risk factors. Both impact each other adversely. The renal profile of professional drivers in Nigeria is not well characterised. We decided to study the prevalence of positive CKD screening amongst professional male long distance drivers in Lagos, Southwest Nigeria so as to quantify the burden and its predictors. METHODS: Two hundred and ninety-three drivers were recruited. Details of their socio-demographic characteristics were obtained. Their anthropometric indices, blood pressure, fasting plasma blood glucose and lipid profile were measured. Serum creatinine was measured and estimated glomerular filtration rate, eGFR, was calculated with Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation. Urinary Albumin Creatinine Ratio (UACR) was determined. A 10 year CVD risk of the subjects was calculated with the Framingham Risk Score (FRS). RESULTS: Mean age of the study population was 44.8 + 9.7 years. The prevalence of alcohol use and smoking were 71.0 and 19.5% respectively. One hundred and twenty-one (62.8%) of the subjects were either overweight or obese while 70(24.1%) had abdominal obesity. The prevalence of hypertension and diabetes were 39.7 and 13.9% respectively. Prevalence of CKD by eGFR< 60 ml/min/1.73m2 or UACR > 30 mg/g was 51.7% (95% CI; 46.0-57.5). The odds for CKD increased with lower HDL-c levels; OR 3.5 (95% CI, 1.1-11.2; p = 0.03) and longer duration of professional driving > 20 years; OR 2.4(95% CI, 1.5-4.0). CONCLUSION: Professional male long distance drivers in addition to having very high prevalence of clustering of both CVD and CKD risk factors have a significant burden of asymptomatic CKD. UACR appears to be an earlier marker of CKD in this population. Health awareness promotion and aggressive risk factor reduction are advocated as ways to reduce this burden.

RESUMO

OBJECTIVE: Echocardiographic screening for Rheumatic Heart Disease (RHD) in Africa has revealed prevalence rates in the range of 0.5-7.4%. There are no recent large population-based studies in Nigeria. The objective of the study was to determine the prevalence of RHD in a large sample of Nigerian school children. METHODS: Using portable transthoracic echocardiography and auscultation, school children aged 5 years to 16 years in Lagos, Nigeria were screened for RHD. Diagnosis was based on the 2012 World Heart Federation echocardiographic criteria. RESULTS: The 4107 children screened had mean age of 11.3 years (SD = 2.6) and 2206 (53.7%) were females. There were 38 children with abnormal echocardiograms, of which 11 (0.27%) showed RHD including two cases of definite RHD giving a prevalence of 2.7/1000 [2.9/1000 in the peri-urban, 2.4/1000 in the urban area). Echocardiography detected RHD 10 times better than auscultation [echocardiography 11 (0.27%) vs. auscultation 1 (0.02%); P = 0.003]. The remaining 27 children with abnormal echocardiograms had congenital heart defects (CHD) giving a prevalence of 6.6/1000 for CHD, a yield higher than for RHD. CONCLUSION: Prevalence of RHD among school children in Lagos, South West Nigeria is low compared to other African countries, possibly due to better access to medical care and antibiotic treatment for infections. Our data provides evidence that RHD prevalence may vary substantially within sub-Saharan Africa, necessitating targeted population-based sampling to better understand disease burden and distribution. Further work is needed to compare within- and between-country RHD prevalence as a basis for programme planning and control efforts.


OBJECTIF: Le dépistage échocardiographique de la cardiopathie rhumatismale (CR) en Afrique a révélé des taux de prévalence compris entre 0,5 et 7,4%. Il n'existe pas de grande étude récente de population au Nigéria. L'objectif de l'étude était de déterminer la prévalence de la CR dans un grand échantillon d'écoliers nigérians. MÉTHODES: A l'aide d'une échocardiographie et d'une auscultation trans-thoraciques portables, des écoliers âgés de 5 à 16 ans de Lagos, au Nigeria, ont été soumis à un dépistage de la CR. Le diagnostic reposait sur les critères échocardiographiques de la Fédération Mondiale du Cœur de 2012. RÉSULTATS: Les 4.107 enfants testés avaient un âge moyen de 11,3 ans (DS = 2,6) et 2.206 (53,7%) étaient de sexe féminin. Il y avait des échocardiogrammes anormaux chez 38 enfants, dont 11 (0,27%) présentaient une CR, y compris deux cas de CR bien définie, donnant une prévalence de 2,7/1000 [2,9/1000 dans les zones périurbaines, 2,4/1000 dans les zones urbaines). L'échocardiographie a détecté une CR 10 fois mieux que l'auscultation [échocardiographie 11 (0,27%) contre auscultation 1 (0,02%); p = 0,003]. Les 27 enfants restants dont les échocardiogrammes étaient anormaux avaient une cardiopathie congénitale (CHD), ce qui donnait une prévalence de 6,6/1.000 pour les cardiopathies congénitales, donnant une prévalence de 6,6/1000, un rendement supérieur à celui de la CR. CONCLUSION: La prévalence de la CR parmi les écoliers à Lagos, dans le sud-ouest du Nigéria, est faible comparée à celle d'autres pays africains, probablement en raison d'un meilleur accès aux soins médicaux et au traitement antibiotique contre les infections. Nos données fournissent des preuves que la prévalence de la CR peut varier considérablement en Afrique subsaharienne, nécessitant un échantillonnage ciblé de la population pour mieux comprendre la charge et la répartition de la maladie. Des études supplémentaires sont nécessaires pour comparer la prévalence de la CR intra- et inter pays en tant que base des efforts de planification et de lutte des programmes.

RESUMO

Background Studies in international literature have shown that Community Pharmacists can make considerable impact in controlling cardiovascular disease risk factors, especially hypertension. In Nigeria, there are no studies on the knowledge of CVD risk factors by Community Pharmacists and their practice of primary prevention. Objective To assess the knowledge of CVD risk factors and practice of primary prevention of CVD amongst Nigerian community pharmacists. Setting Community Pharmacists in Lagos, Nigeria. Methods This cross-sectional study involved 168 Community Pharmacists. Their knowledge of CVD risk factors was assessed with the Heart Disease Fact Questionnaire. Their opportunistic screening practices for CVD risk factors (primary prevention) were also assessed. Main outcome measures Knowledge of CVD risk factors and practice of primary CVD prevention. Results The mean age of the participating pharmacists was 41.7 (± 11.2) years and 87 (51.8%) of them were males. The median number of years of practice was 9.0 (3-15) years. Mean knowledge score was 22.1 (± 3.0) with 154 (91.7%) of the subjects scoring above 70%. An average of 95.5% of the participants correctly identified hypertension, smoking, dyslipidaemia, obesity, physical inactivity and diabetes as CVD risk factors. Eighty-one (48.2%) had good practice of primary CVD prevention. Conclusion: This study shows that Community Pharmacists in Nigeria have very good knowledge level of CVD risk factors and almost 50% of them practised primary prevention of CVD.

RESUMO

Cooking with dirty-burning fuels is associated with health risk from household air pollution. We assessed the prevalence of and factors associated with the use of cooking fuels, and attitudes and barriers towards use of liquefied petroleum gas (LPG). This was a cross-sectional, population-based survey conducted in 519 households in Lagos, Nigeria. We used a structured questionnaire to obtain information regarding choice of household cooking fuel and the attitudes towards the use of LPG. Kerosene was the most frequently used cooking fuel (n = 475, 91.5%; primary use n = 364, 70.1%) followed by charcoal (n = 159, 30.6%; primary use n = 88, 17%) and LPG (n = 86, 16.6%; primary use n = 63, 12.1%). Higher level of education, higher income and younger age were associated with LPG vs. kerosene use. Fuel expenditure on LPG was significantly lower than for kerosene ( N (Naira) 2169.0 ± 1507.0 vs. N 2581.6 ± 1407.5). Over 90% of non-LPG users were willing to switch to LPG but cited safety issues and high cost as potential barriers to switching. Our findings suggest that misinformation and beliefs regarding benefits, safety and cost of LPG are important barriers to LPG use. An educational intervention program could be a cost-effective approach to improve LPG adoption and should be formally addressed through a well-designed community-based intervention study.

RESUMO

BACKGROUND: Professional drivers are known to be at high risk of cardiovascular disease (CVD). This study was carried out to highlight these risk factors and their predictors among male long-distance professional bus drivers in Lagos, south-west Nigeria, with a view to improving health awareness in this group. METHOD: Socio-demographic data, anthropometric indices, blood pressure, fasting plasma blood glucose levels and lipid and physical activity profiles of 293 drivers were measured. RESULTS: Mean age of the study population was 48 ± 9.7 years; 71.0 and 19.5% of the drivers used alcohol and were smokers, respectively; and 50.9% were physically inactive. The prevalence of overweight and obesity was 41.7 and 21.1%, respectively, while 39.7 and 13.9% were hypertensive and diabetic, respectively. Ninety (31.3%) subjects had impaired fasting glucose levels while 56.3% had dyslipidaemia. Predictors of hypertension were age and body mass index (BMI). BMI only was a predictor of abnormal glucose profile. CONCLUSION: Professional male long-distance bus drivers in this study showed a high prevalence of a cluster of risk factors for CVD.

RESUMO

BACKGROUND: Factors associated with tobacco smoking are useful in designing tobacco control programs. OBJECTIVES: To estimate the prevalence of and factors associated with tobacco smoking among long-distance drivers. METHODS: This was a cross-sectional study. Stratified cluster sampling approach was used to select drivers based on if they received annual health screening (AHS) or not (non AHS). We used a structured questionnaire to obtain information and weighted the resulting observations to derive population based estimates. Association between tobacco smoking and socio-demographic factors was explored in multivariate models. RESULTS: 414 male drivers, mean age 43.6 (standard error 0.6) years. Population weighted prevalence of current smoking was 18.9% (95% CI: 14.3-23.4) of all drivers, 6.5% (95% CI: 2.6-10.4) of AHS drivers and 19.5 (95% CI: 14.7-24.2) of non AHS drivers (p<0.001). In multivariate models, having close friends that smoked (OR= 6.36, 95% CI= 2.49 - 16.20) cargo driving (OR= 2.58, 95% CI= 1.29 - 5.15) and lower education levels (OR for post-secondary education vs. primary education or less= 0.17, 95% CI= 0.04 - 0.81) were associated with current smoking. CONCLUSION: Prevalence of tobacco smoking is higher among non AHS compared to AHS drivers. Having close friends that smoked, cargo driving, and lower education levels were associated with current smoking.

RESUMO

Depression is a major issue in heart failure (HF). Depression is present in about one in five HF patients, with about 48 % of these individuals having significant depression. There is a wide variation in reported prevalences because of differences in the cohorts studied and methodologies. There are shared pathophysiological mechanisms between HF and depression. The adverse effects of depression on the outcomes in HF include reduced quality of life, reduced healthcare use, rehospitalisation and increased mortality. Results from metaanalysis suggest a twofold increase in mortality in HF patients with compared to those without depression. Pharmacological management of depression in HF has not been shown to improve major outcomes. No demonstrable benefits over cognitive behavioural therapy and psychotherapy have been demonstrated.

RESUMO

INTRODUCTION: The impact of Obstructive sleep apnea (OSA) in worsening outcomes is profound, especially in the presence of comorbid conditions. This study aimed to describe the proportion of patients at a high risk of OSA in our practice setting. METHODS: The STOP BANG questionnaire and the Epworth Sleepiness scale were used to assess for OSA risk and excessive daytime sleepiness respectively. Hospitalized patients and out-patients were recruited. Intergroup differences in continuous variables were compared using the analysis of variance. The proportion of patients with high risk of OSA and excessive daytime sleepiness was presented as frequencies and group differences compared with the Pearson χ(2) test. Independent risk predictors for OSA were assessed in multivariate logistic regression analysis. RESULTS: A total of 1100 patients (53.4% females) participated in the study. Three hundred and ninety nine (36.3%) had a high risk of OSA, and 268 (24.4%) had excessive daytime sleepiness. Of the participants with high OSA risk, 138 (34.6%) had excessive daytime sleepiness compared to 130 (18.5%) of those with low OSA risk (p). CONCLUSION: A significant proportion of patients attending our tertiary care center are at high risk of OSA.
