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. Minitab™ 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 ECG-LVH 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.

Lipid disorders in hospital attendants in Kumasi, Ghana.

BACKGROUND: Lipid disorders are common worldwide and contribute to a significant proportion of the burden of atherosclerotic cardiovascular diseases. OBJECTIVES: To determine the prevalence of lipid disorders among patients reporting at Komfo Anokye Teaching Hospital (KATH), Kumasi, Ghana. DESIGN: Cross-sectional study. SETTING: Directorate of Medicine and Polyclinic outpatient clinics of KATH. PARTICIPANTS: A total of 424 patients, 20 years and over reporting for the first time to KATH were recruited. 77 had neither diabetes mellitus (DM) nor systemic hypertension (HPT) (controls), 94 had only DM, 109 had only HPT and 144 had both. METHODS: A questionnaire was administered after informed consent. Anthropometric measurements were then taken and blood investigations including total cholesterol (TC), high-density lipoprotein cholesterol (HDL) and triglycerides (TG) were done. Low-density lipoprotein cholesterol (LDL) was calculated using the Friedwald formula. The atherogenic index or ratio was the ratio of TC to HDL. RESULTS: The prevalence of lipid abnormalities was 60% for high TC, 32% for high TG, 17% for low HDL and 61% for high LDL. The mean (± standard deviation) TC was 5.33 (± 1.31) mmol/L, mean TG was 1.52 (± 0.81) mmol/L, mean HDL was 1.65 (± 0.57) mmol/L and mean LDL was 3.42 (± 1.22) mmol/L. The mean atherogenic index was 3.40 and 9% of the participants had an atherogenic index more than or equal to 5. CONCLUSION: The prevalence of lipid disorders was high in adult patients in Kumasi and there is the need to increase awareness, screening, detection, treatment and control of these disorders.

Stroke in Ashanti region of Ghana.

OBJECTIVE: To determine the morbidity and mortality in adult in-patients with stroke admitted to the Komfo Anokye Teaching Hospital (KATH). METHODS: A retrospective study of in-patients with stroke admitted to the KATH, from January 2006 to december 2007 was undertaken. Data from admission and discharge registers were analysed to determine stroke morbidity and mortality. RESULTS: Stroke constituted 9.1% of total medical adult admissions and 13.2% of all medical adult deaths within 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.
