Resting electrocardiographic and echocardiographic findings in an urban community in the Gambia
The presence of Left Ventricular Hypertrophy (LVH) in a patient with systemic hypertension deserves serious attention and makes its clinical diagnosis a priority. Over the years various criteriahave been proposed for the electrographic (ECG) diagnosis of LVH and the sensitivity and specificity of these criteria have been extensively studied in Caucasians. Recent evidence indicates that they areinapplicable to people of African descent. Unlike echocardiography (ECHO), the ECG is generally available, cheap but has a lower sensitivity in detecting LVH compared to echocardiography. Thisstudy was conducted to evaluate ECG criteria against 2-dimensional (2-D) guided M-mode echocardiography in the diagnosis of LVH in adult Gambians. Secondly, to determine the ECG criteria usingthe Minnesota, Araoye, Sokolow and Lyon or Wolff criteria with the overall best accuracy for the diagnosis of LVH. Two hundred and eight (208) consecutive patients with systemic hypertension (BP.140/90mmHg) with or without treatment and an age matched group of 108 non-hypertensive patients were enrolled from outpatient clinics. A questionnaire was filled. All patients were investigated with 2-D guided M-mode echocardiography and a standard 12-1ead ECG. Anthropometric measurements were also taken. The gold standard was the Penn formula to determine the left ventricular mass index (of 125 g/m2 in males and 110 g/m2 in females as the cut-off for LVH). Using this gold standard the prevalence of echocardiographic LVH was 47.5% and 27.8 % in the hypertensives and non-hypertensives respectively (P 0.05). Sokolow and Lyon criterion had overall best accuracy for the electrocardiographic diagnosis of left ventricular hypertrophyin hypertensives and is further recommended for use as such. But for non-hypertensives, the Wolff criterion had overall best accuracy
Electrocardiographic Left Ventricular Hypertrophy Among Gambian Diabetes Mellitus Patients
Background: The global prevalence of diabetes and its complications is increasing worldwide. Its role in coronary heart disease has been linked with the presence of left ventricular hypertrophy (LVH). The present study aims to determine the prevalence of electrocardiographic left ventricular hypertrophy (ECG-LVH) in adult diabetic subjects, its epidemiological and clinical correlates.Methods: A descriptive cross-sectional study involving 534 patients was conducted at the Edward Francis Small Teaching Hospital (formerly Royal Victoria Teaching Hospital), The Gambia. Four hundred and forty patients were included using a standard questionnaire. Anthropometry, laboratory investigations and electrocardiogram were carried out. We used the Lewis, Cornell, and Sokolow-Lyon Voltage criteria to define ECG-LVH. MinitabTM statistical software version 13.20 was used for analysis.Results: 146 (35.2%) patients had ECG-LVH using all 3 criteria and this prevalence was higher among women being 116 (79.5%). A generally high prevalence of overweight (155/37.4%) and obesity (119/28.6%) was observed among study participants, and both clinic-day systolic and diastolic blood pressure (BP) were significantly higher in those with ECG-LVH. Poor diabetes control was observed in both groups.Conclusion: There was a high prevalence of ECGLVH and it is especially so with combining multiple criteria, hence the need for screening. Clinic-day hypertension was associated with ECG-LVH hence the need for diagnosing and aggressive treatment of hypertension in patients with diabetes mellitus.Keywords: Diabetes mellitus, ECG-LVH, The Gambia, voltage criteri
Stroke in Ashanti region of Ghana
Objective: To determine the morbidity and mortality in adult in-patients with stroke admitted to the KomfoAnokye Teaching Hospital (KATH).Methods: A retrospective study of in-patients with stroke admitted to the KATH, from January 2006 todecember 2007 was undertaken. Data from admission and discharge registers were analysed to determinestroke morbidity and mortality.Results: Stroke constituted 9.1% of total medical adult admissions and 13.2% of all medical adult deathswithin the period under review. The mean age of stroke patients was 63.7 (95% ci=62.8, 64.57) years. Males were younger than females. The overall male to female ratio was 1:0.96, and the age-adjusted risk of death from stroke was slightly lower for females than males (relative risk= 0.88; 95% ci=0.79, 1.02, p=0.08). The stroke case fatality rate was 5.7% at 24 hours, 32.7% at 7 days, and 43.2% at 28 days.Conclusion: Stroke constitutes a significant cause of morbidity and mortality in Ghana. Major efforts are needed in the prevention and treatment of stroke. Population-based health education programs and appropriate public health policy need to be developed. This will require a multidisciplinary approach of key players with a strong political commitment. There is also a clear need for further studies on this topic including, for example, an assessment of care and quality of life after discharge from hospital. The outcomes of these studies will provide important information for the prevention efforts.Keywords: Stroke, Cerebrovascular disease, CVD, Komfo Anokye Teaching Hospital, Ghan
