Abstract
Background Abnormalities of glucose metabolism are associated with abnormal left ventricular geometry (LV) independent of atherosclerosis. Abnormal LV geometry, a predictor of premature cardiovascular events, indicates presence of subclinical target organ damages. Screening for abnormal LV geometry in diseases of abnormal glucose metabolism is desirable as part of their management protocol. Aim To assess the left ventricular geometry in normotensive type II diabetic patients. Cross-sectional, descriptive, hospital-based study. One hundred normotensive type II diabetic patients drawn from the Endocrinology and Family Medicine Clinics of a tertiary hospital were age- and gender-matched with 100 apparently healthy controls. Participants meeting the criteria and informed consent proceeded for clinical evaluation, biochemical assessment, electrocardiography, and echocardiography using the American Society of Echocardiography guideline. Materials and Methods Data were analyzed using the Statistical Package for Social Sciences [SPSS] version 25.0 (Chicago Illinois, USA). Results Mean age of study and control groups was (55.56 ± 9.89 versus 55.47 ± 10.7) years (χ2 = 0.062, P = 0.951). The mean duration of diabetes illness was 6.57 ± 6.26 years. Prevalence of abnormal LV geometry was 51% (study) versus 18% (control) FT, P < 0.001). Concentric remodeling was the predominant geometry in 36% of study versus 11% of controls, followed by eccentric hypertrophy in 11% (study) versus 4% (control) and concentric hypertrophy in 4% (study) versus 3% (control). Geometry was normal in 49% of study against 82% in the controls (FT, P < 0.001). Significant association existed between LV geometry and duration of diabetes (χ2 = 10.793, P = 0.005). Conclusion Abnormal LV geometry is highly prevalent in normotensive diabetic patients.

Abstract
INTRODUCTION The elderly hypertensive patients often have increased prevalence of cardiometabolic risk factors and their attendant co-morbidities. The aim of this study was to determine the prevalence of cardiometabolic risk factors and blood pressure control among elderly hypertensive patients, and to determine the influence of modifiable cardiometabolic risk factors on the control of hypertension among elderly hypertensive patients. SUBJECTS AND METHODS A case-control comparative and hospitalbased study involving a total of 190 consenting elderly (>65 years), hypertensive patients (subjects) (n=100) and normotensive controls (n=90) was carried out over a period of ten months. Using interviewer-administered questionnaire, biodata and information regarding their lifestyle was obtained. Standard protocols were used to measure blood pressure, weight, height, waist circumference, fasting plasma glucose and fasting lipid profile of the subjects. Body mass index was derived from weight and height. RESULTS The mean age of the subjects was 71.5 ± 6.3 years and the controls was 72.3 ± 7.2 years. Forty-eight percent (48%) and 47.8% of the subjects and controls were females (p = 0.651). The level of control of hypertension was poor in over two-thirds (68%) of the elderly hypertensive patients. The prevalence of modifiable cardiometabolic risk factors burden was higher in the hypertensive subjects when compared with the controls. Prevalence of Dyslipidaemia was 76% in the subjects and 51% in the controls (p = 0.004). Prevalence of Diabetes Mellitus was 40% among the subjects and 17.8% in the controls (p = 0.0001); prevalence of Obesity was 24% in the subjects and 4.4% in the controls (p=<0.001); prevalence of excess alcohol intake was 49% in the subjects and 14.4% in the controls (p=<0.001). Prevalence of sedentary life style was high in both the subjects (53%) and controls (50%), p=0.679. Poor blood pressure control was predicted by dyslipidaemia and central obesity. CONCLUSION The level of control of hypertension was poor among the elderly and modifiable cardiometabolic risk factors were relatively prevalent. Central obesity and dyslipidaemia were predictive of poor control of hypertension. Addressing these factors may therefore improve blood pressure control.

Abstract
Marfan syndrome is an uncommon inheritable connective tissue disease which affects the cardiovascular system. This paper presents two cases of Marfan Syndrome with predominant aortic root disease that were seen at the Cardiology Clinic of University of Nigeria Teaching Hospital, Enugu, Nigeria. Their biography, clinical features and echocardiography parameters were captured using structured questionnaire. Both were young males in their 4th decade of life, and had advanced aortic root diseases which were complicated by left ventricular failure in both, while one of them had aortic dissection and ischemic stroke. Young adult Nigerians with Marfan syndrome presented with advanced aortic root diseases, heart failure, aortic dissection and stroke.

Abstract
BACKGROUND Electrocardiographic (ECG) abnormalities are prevalent in subjects with human immunodeficiency virus (HIV) infection. In this study, three groups of subjects were investigated and the prevalence of ECG abnormalities was analysed. METHODS A cross-sectional study was carried out on adults between November 2010 and November 2011 at the University of Nigeria Teaching Hospital, Enugu, Nigeria. One hundred HIV-infected patients on highly active anti-retroviral therapy (HAART), 100 HIV-infected HAART-naïve patients and 100 HIV-negative controls were recruited. Twelve-lead electrocardiograms were done on all subjects. Data were analysed using the chi-squared, Student's t-, one-way ANOVA and Duncan post hoc tests. RESULTS Left-axis deviation was seen in 15 (16%) of the HIV-positive subjects on HAART, 10 (13.7%) of the HAART-naïve subjects and eight (21%) of the controls (p = 0.265). Eight (11%) subjects with left ventricular hypertrophy (p < 0.001) and two (2.7%) with ST-segment elevation were found among the HIV-positive HAART-naïve subjects (p = 0.134). Prolonged QTc interval was seen in 17 (18.2%) of the HIV-positive patients on HAART, 12 (16.4%) of the HIV-positive HAART-naïve patients and four (10.5%) of the controls (p = 0.012). CONCLUSION The prevalence of ECG abnormalities was higher in the HIV-positive patients on HAART (93%) and the HIV-positive HAART-naïve patients (73%) compared to the controls.

Abstract
Background: Pulmonary hypertension is a common complication of degenerative mitral valve disease, and contributes significantly to both morbidity and mortality. The use of medications for reduction of pulmonary pressure in patients is not a common practice by most physicians in this part of the world because of the absence of data on pulmonary hypertension. Aim: The authors set out to find the prevalence of pulmonary hypertension in patients with degenerative mitral valve disease and to determine if there are gender differences in affectation. This will form a basis for future research on the management of pulmonary hypertension in sub-Saharan Africa. Subjects and Methods: The echocardiographic records of 1390 patients carried out over a period of 4 years were retrospectively reviewed. The examinations were done with a Logic 500 MD echocardiographic machine. Tricuspid valve regurgitation velocity above 250 cm/s defined pulmonary hypertension. Data obtained included presence of degenerative mitral valve disease, pulmonary hypertension, age, and gender. Results: A total of 1390 echocardiogram reports done at Conquest Medical Imaging, Enugu, from July 2009 to August 2013 were retrospectively reviewed. Degenerative mitral valve disease was noted in 18.7% of the patients, (259/1390) made up of 149 males and 110 females with a mean age of 68.3 (14.4) years. Pulmonary hypertension was present in 30% of the patients (78/259) and affected males more than females. Conclusion: Pulmonary hypertension is common in patients with degenerative mitral valve disease in Enugu, and affects males more than females.

Abstract
Cardiovascular diseases (CVD) were previously considered a problem of the developed nations only. Emerging facts show that CVD and their risk factors are now prevalent in developing countries. We carried out a cross-sectional, population-based survey to determine the relation between place residence (rural or urban) and the burden of CVD risk factors in South East Nigeria. Hypercholesterolaemia, hypertension, abnormal blood glucose and obesity were assessed for, in middle-aged and elderly residents of two communities in Enugu, South East Nigeria. A total of 543 adults (308 at Ogwofia Owa and 235 at Emene) participated in the study. The mean and 95% CI for mean of the characteristics of subjects showed that they were in the middle-age group with apparently normal mean cardiovascular risk indices except for systolic and diastolic blood pressure indices which suggested pre-hypertension. The subjects residing in the rural area were older than those residing in the urban area but cardiovascular risk factors had higher mean values in urban residents except systolic blood pressure (SBP). The most prevalent cardiovascular risk factors in the study group were hypertension and obesity. Urban residence was found to influence the prevalence of risk factors, specifically obesity and diastolic hypertension.

Abstract
BACKGROUND Transthoracic echocardiography (TTE) is one of the most commonly performed cardiac investigations. It can provide comprehensive information about cardiac structure and function, helping to establish a diagnosis and guide therapy, and it is no longer the preserve of the specialist cardiology department. Previous studies on echocardiographic findings in our environment had documented valvular heart disease, hypertensive heart disease and congenital heart diseases as the commonest echocardiographic findings in Nigerians. AIMS The study aimed to provide an update on the common echocardiographic findings in different age groups in this part of the world, since some of the previous similar studies were done over a decade ago. MATERIALS AND METHODS We reviewed the echocardiogram reports of 608 consecutive patients done from July 2009 to October 2011 at a private echocardiographic laboratory in Enugu, South-East Nigeria. Data was analyzed for age, gender and echocardiographic findings. RESULTS The age range of the patients was from 3 days to 98 years with a mean age of 46.4 ± 21.4 years. The mean age of the males was 47.6 ± 21.3 years, while the mean age of the females was 45.2 ± 21.1 years. The commonest echocardiographic abnormality in children was atrial septal defect, while rheumatic heart disease was the commonest in adolescents and young adults. Left ventricular diastolic dysfunction and degenerative valvular diseases respectively were the commonest in the middle-aged and elderly populations in this study. CONCLUSION This study has reaffirmed rheumatic heart disease (predominantly mitral valve regurgitation) as the commonest cardiac abnormality in adolescents and young adults. Degenerative valvular diseases, left ventricular diastolic dysfunction, and atrial septal defects were the commonest abnormalities in the elderly, middle-aged population and children, respectively.

Abstract
Pulmonary hypertension is an emerging complication of sickle cell anaemia with associated increased risk of mortality. In order to evaluate the clinical and electrocardiographic findings in adult sickle-cell patients with pulmonary hypertension, a cross sectional study was conducted on sixty two sickle cell anaemia patients and sixty two age and sex matched normal controls. Elevated pulmonary artery pressures (PAP), defined by PAP ≥ 30 mm Hg on echocardiography, was demonstrated in 41.9% of patients with sickle cell anaemia and in 3.2% of the controls; χ2 = 26.571, P < 0.001. Right ventricular hypertrophy, increased P-wave duration, QTc interval, and QTc dispersion were significantly associated with pulmonary hypertension. Significant correlation was found between mean PAP and (1) Frequency of crisis (Spearman correlation = 0.320; P = 0.011), (2) body mass index (Pearson's correlation = −0.297; P = 0.019), and (3) QTc interval (Pearson's correlation 0.261; P = 0.040). Pulmonary hypertension in adult sickle anaemia patients is associated with electrocardiographic evidence of right ventricular hypertrophy, and correlates significantly with frequency of vaso-occlusive crisis, and QTc interval. The observations by this study tend to suggest that these parameters could be useful for early detection and prevention of pulmonary hypertension in patients with sickle cell anaemia.

Abstract
The outcomes of drug treatment for male infertility remain conjectural, with controversial study results. Our pilot study employed a randomized, placebo-controlled, crossover methodology with intention-to-treat analysis. Thirty-three men with idiopathic oligospermia were randomized to start either daily oral lisinopril 2.5 mg (n = 17) or daily oral placebo (n = 16). Lisinopril was found to cause a normalization of seminal parameters in 53.6% of the participants. Although the mean ejaculate volume was unchanged (P ≥ 0.093), the total sperm cell count and the percentage of motile sperm cells increased (P ≤ 0.03 and P < 0.001, respectively), whereas the percentage of sperm cells with abnormal morphology decreased (P ≤ 0.04). The pregnancy rate was 48.5%, and there was no serious adverse drug event. It is concluded, albeit cautiously, that prolonged treatment with 2.5 mg/day of oral lisinopril may be well tolerated in normotensive men with idiopathic oligospermia, may improve sperm quantity and quality, and may enhance fertility in approximately half of those treated.

Abstract
Aim There are few studies to be found in the literature on ankle–brachial index in sickle cell disease. The aim of this study was to compare ankle–brachial index of steady-state adult sickle cell anaemia patients with that of normal controls. Methods A descriptive cross-sectional study of 62 sickle cell anaemia patients and 62 age- and gender-matched normal controls was carried out in the adult outpatient sickle cell clinics and the cardiac centre of the University of Nigeria Teaching Hospital (UNTH), Enugu, Nigeria from February to August 2007. The supine brachial and ankle blood pressures were measured separately with the cuff of the mercury sphygmomanometer applied to the right arm and right calf, respectively. Results The ankle systolic blood pressure was lower in patients with sickle cell anaemia than in the controls (p < 0.001). The mean indices for ankle–brachial index were 0.88 ± 0.09 and 1.03 ± 0.06, respectively for patients and controls. This difference was statistically significant (p < 0.001). Seventy three per cent of the patients had ankle–brachial index less than 0.9 compared with controls (5%). This was also significant (p < 0.001).

Abstract
BACKGROUND There is a lack of data on the relationship between cardiovascular autonomic neuropathy (CAN) and electrocardiographic parameters in sickle cell anaemia. AIMS AND OBJECTIVES The purpose of the study was to compare the electrocardiographic findings in adult sickle cell anaemia patients with CAN with those of patients without this complication. METHODS A cross sectional study was done using 62 consecutively recruited sickle cell anaemia patients who met the inclusion criteria for the study. Cardiovascular autonomic dysfunction was determined based on abnormal values in at least two of five non-invasive tests: Valsalva manoeuver, heart rate variation during deep breathing, heart rate response to standing, blood pressure response to sustained hand grip, and blood pressure response to standing. The subjects were subsequently evaluated with electrocardiography. RESULTS Sickle cell anaemia patients with CAN had statistically significantly increased P-wave duration (p < 0.001), PR-interval (p < 0.05) and QTc dispersion (p < 0.05) compared with patients without CAN. Significantly increased frequencies of Q waves and first degree atrio-ventricular block were found in patients with CAN than in those without CAN (p = 0.026, p = 0.014, respectively). Significant correlations were noted between the severity of CAN [number of abnormal autonomic function tests (AFT)] and (1) P-wave duration (p = 0.008), (2) PR- interval (p = 0.013). Significant association was found between the number of abnormal AFT and (1) presence of Q-waves, and (2) degree of anaemia (haematocrit class). CONCLUSION Electrocardiographic features consistent with atrio-ventricular and ventricular repolarization abnormalities are associated with CAN in sickle cell anaemia. Further studies are required to evaluate the prognostic implications of these findings in sickle cell patients with cardiovascular autonomic dysfunction.

Abstract
Various forms of cardiac arrhythmias have been documented in hypertensive subjects, and hypertension is an important risk factor for the development of atrial and ventricular arrhythmias and sudden death. Electrocardiography at rest easily documents significant arrhythmias in patients, and this study was carried out to determine the types and frequency of arrhythmias in hypertensive subjects at first presentation in the Hypertension Clinics of the University of Nigeria Teaching Hospital (UNTH) Enugu, Nigeria. The study was hospitalbased and retrospective in nature. The resting 12lead ECG reports of 346 consecutive hypertensive subjects seen at the Hypertension clinics of the UNTH Enugu over a 14 month period were retrieved from the case files and studied. Other information obtained from the case files included the age and gender of the subjects. The mean age of the subjects was 57.3 years. Ninety-five of the subjects had arrhythmias representing 27% of the study population, out of which fifty-five were males (57.9%) and forty were females (42.1%). However 26.9% of all the male subjects had arrhythmias while 28.2% of all the females had arrhythmias. Multiple ventricular ectopics, sinus tachycardia, sinus bradycardia and atrial fibrillation were the most prevalent arrhythmias. This study showed that a significant proportion of hypertensive subjects present initially with significant rhythm disturbances.

Abstract
Cardiovascular diseases (CVDs) are the main causes of death in industrialized countries, and are significant causes of morbidity and mortality in sub-Saharan Africa. Hypertension is the most common cardiovascular disease in Nigerians, and the risk of CVD associated with hypertension is independent of other risk factors. Despite the high level of awareness of its presence in the developed countries, the level of control is still poor. CVDs tend to be commoner in urban settlements, and it has been hypothesized that rural sub-Saharan Africa is at an early stage of epidemiological transition from communicable to non-communicable diseases (NCD) because of the gradual adoption of unhealthy lifestyles. This study aimed at describing the pattern of blood pressure indices among the hypertensive residents of a rural community in South East Nigeria. A total of 858 individuals comprising 247 males and 611 females took part in the study. 46.4% of the subjects had hypertension. Hypertension was commoner in the males (50.2% vs. 44.8%) (χ(2)(1) = 1.484; P = 0.223). The males were significantly older and heavier than the females while the females had higher mean values of BMI and WC. The prevalence of hypertension is becoming alarmingly high in the rural communities of sub-Saharan Africa.

Abstract
Background The prognostic implications of P-wave dispersion in patients with a variety of cardiac disease conditions are increasingly being recognised. The relationship between P-wave dispersion and left ventricular function in sickle cell anaemia is unknown. Objective This study was aimed at evaluating the relationship between P-wave dispersion and left ventricular function in adult Nigerian sickle cell anaemia patients. Methods Between February and August 2007, a total of 62 sickle cell anaemia patients (aged 18–44 years; mean 28.27 ± 5.58) enrolled in the study. These were drawn from patients attending the adult sickle cell clinic of the University of Nigeria Teaching Hospital, Ituku-Ozalla, Enugu. An equal number of age- and gender-matched normal subjects served as controls. All the participants were evaluated with electrocardiography and echocardiography. P-wave dispersion was defined as the difference between the maximum and minimum P-wave duration measured in a 12-lead electrocardiogram. Results P-wave duration and P-wave dispersion were significantly higher in patients than in controls. Significant correlation was demonstrated between P-wave dispersion and age in the patients (r = 0.387; p = 0.031). A comparison of subsets of sickle cell anaemia patients and controls with comparable haematocrit values (30–35%) showed significantly higher P-wave duration and P-wave dispersion in the patients than in the controls. The P-wave duration in patients and controls, respectively, was 111.10 ± 14.53 ms and 89.14 ± 16.45 ms (t = 3.141; p = 0.006). P-wave dispersion was 64.44 ± 15.86 ms in the patients and 36.43 ± 10.35 ms in the controls (t = 2.752; p = 0.013). Significant negative correlation was found between P-wave dispersion and left ventricular transmitral E/A ratio (r = –0.289; p = 0.023). Conclusion These findings suggest that P-wave dispersion could be useful in the evaluation of sickle cell patients with left ventricular diastolic dysfunction. Further prospective studies are recommended to evaluate its prognostic implication on the long-term disease outcome in sickle cell disease patients.

Abstract
BACKGROUND Cardiovascular system abnormalities are common causes of morbidity and mortality in sickle cell anaemia. OBJECTIVES The study aims at determining the pattern of electrocardiographic changes in adult Nigerian sickle cell anaemia patients. METHODS A descriptive cross sectional study was done on sixty sickle cell anaemia patients seen at the adult sickle cell clinic of University of Nigeria Teaching Hospital (UNTH) Enugu, and sixty age and sex matched normal controls. All the subjects had clinical evaluation as well as electrocardiographic examination. RESULTS The mean heart rate, P-wave duration, P-wave dispersion, PR interval, QRS duration, QRS dispersion, QTc interval and QTc dispersion were significantly higher in the patients than in the control group. Electrocardiographic abnormalities identified by this study were: left ventricular hypertrophy (75%; 1.7%), left atrial enlargement (40%; 0%), biventricular hypertrophy (11%; 0), ST-segment elevation (10%; 0%) and increased P-wave and QTc dispersions. ST segment elevation was found more in patients with moderate and severe anaemia (P= 0.02, Spearman correlation r= 0.342; P= 0.007), CONCLUSION Sickle cell anaemia is associated with significant electrocardiographic abnormalities. Further prospective studies are recommended to evaluate the prognostic significance of the electrocardiographic intervals dispersion on the long term disease outcome in sickle cell anaemia.

Abstract
AIM AND OBJECTIVE This study was aimed at comparing the arterial blood pressures in steady state adult sickle cell patients with those of age- and sex-matched healthy controls. METHODS A descriptive cross-sectional study of 62 sickle cell anemia patients and 62 age- and sex-matched healthy controls was carried out in the adult outpatient sickle cell clinics and the cardiac center of the University of Nigeria Teaching Hospital (UNTH), Enugu, Nigeria. Brachial blood pressures were measured in the right arm in all subjects. RESULTS Significant increase in pulse rate was found in the study subjects (87.68 ± 8.91 bpm) compared with the controls (72.13 ± 6.79 bpm) (p<0.05). The mean systolic blood pressure was comparable in the two groups. However, the patients had significantly lower diastolic blood pressure, lower mean arterial blood pressure, as well as a higher pulse pressure than the control subjects. Significant correlations were found between blood pressure indices and hematocrit, body mass index, frequency of crisis, and body surface area. CONCLUSION Relatively lower arterial blood pressure is a significant finding in patients with sickle cell anemia. Hematocrit, frequency of crisis, body mass index, and body surface area are significant determinants of blood pressure indices in sickle cell anemia.

Abstract
BACKGROUND Rheumatic heart disease is one of the commonest causes of heart disease in Nigeria. Previous studies on rheumatic heart disease in Nigeria were either clinical or retrospective echocardiographic studies. This study was aimed at determining the burden of chronic rheumatic mitral valve disease, pattern of valvular involvement, severity and associated valvular lesions, using echocardiography. PATIENTS AND METHODS Between May, 2004 and April 2005, patients with symptomatic rheumatic heart disease, seen in the cardiac clinics of University of Nigeria Teaching Hospital, Enugu, were recruited for the study. The patients were investigated non-invasively with M-mode, Two-dimensional, Pulsed wave, Continuous wave and colour flow Doppler echocardiographic techniques in order to assess the mitral and other intracardiac valves for evidence of rheumatic heart disease. RESULTS There were a total of 55 patients, 39 (70.9%) females and 16 (29.1%) males with a mean age of 29.34 +/- 11.57 years. Mitral valve disease was found in 54 (98.2%) and isolated aortic valve disease in 1 (1.8%) of cases. Mitral regurgitation occurred in 64.8%, mixed mitral valve disease in 25.9% and pure mitral stenosis in 9.3%. Mitral valve disease was associated with aortic valve disease in 33.3%, with tricuspid valve disease in 24.1% and with functional pulmonary incompetence in 9.3% of cases. CONCLUSION Rheumatic heart disease in Nigeria is essentially a disease of the mitral valve as seen elsewhere in the world. Echocardiography should be done routinely for patients with rheumatic heart disease to facilitate accurate diagnosis and definitive treatment.

Abstract
BACKGROUND Muscular dystrophy is not an uncommon entity in Nigerian medical clinics. The facioscapulohumeral type represents a rare variety of the disorder with its own distinctive characteristics but is not expected to have significant cardiac manifestations. METHOD The case report of a 17-year-old Nigerian female with facioscapulohumeral muscular dystrophy and significant cardiac dysfunction is presented and the relevant literature is reviewed. RESULTS A 17-year-old Nigerian female presented with 18 month history of shortness of breath on mild to moderate exertion, generalized weakness, weight loss and abnormal gait. Leg swelling developed a few weeks prior to presentation. Intrauterine life and early childhood were uneventful while her family history was unremarkable. She had typical features of facioscapulohumeral muscular dystrophy but in addition demonstrated evidence of significant cardiac impairment, which is uncommon and not typically expected in this disorder. CONCLUSION It is important for clinicians to comprehensively evaluate every patient presenting with a hitherto "clear "diagnosis in order to unmask unexpected associated clinical details.
