Intra-Cardiac Masses in Adults: A Review of Echocardiogram Records at Two Echocardiographic Laboratories in Enugu; South-East Nigeria

Background: Transthoracic echocardiography (TTE) is an excellent initial diagnostic technique used to evaluate and diagnose cardiac masses; even though transoesophageal echocardiography (TEE) provides superior image resolution and better visualization of cardiac masses; especially in patients with suboptimal transthoracic echocardiographic studies. TTE is the clinical procedure of choice for identification of left ventricular thrombi. TTE has greater than 90 sensitivity and greater than 85 specificity for detection of left ventricular thrombi and is probably superior to the sensitivity and specificity of TEE; especially for apical thrombi.Aims: The study aimed to identify the common types of cardiac masses and their commonest locations in the heart.Materials and Methods: We did a retrospective review of our echocardiogram reports from May 2003 to July 2012 to identify the frequency of intra-cardiac masses in adults; as well as the gender distribution and commonest location of these masses.Results: There were 2;814 echo examinations in adults over this period; comprising 1;661 males (59.1) and 1;153 females (40.9). Intra-cardiac masses were found in 20 of these patients representing 0.7 of the study population. Thrombi were the commonest masses noted in our study; and there were more masses in the atria than in the ventricles. The left heart chambers also had more masses than the right heart chambers. There was no sex difference in the frequency of cardiac masses.Conclusion: Intra-cardiac masses are rare; and transthoracic echocardiography is still valuable in the diagnosis and initial characterization of cardiac masses

Evaluation of blood pressure and indices of obesity in a typical rural community in eastern Nigeria

Aim: With increasing urbanization of lifestyle; cardiovascular morbidity and mortality have been on the increase in Africans. Studies on cardiovascular risk factors in rural communities in South East Nigeria are scarce. This study focused on hypertension and obesity in adult Nigerians dwelling in a rural setting in Eastern Nigeria. Materials and Methods: A total of 218 participants from the rural community were recruited into the study. A questionnaire was used to assess prior knowledge of their weight and blood pressure status as well as drug history for those found to have ypertension. Each participant's blood pressure was measured and any value =140/90 mmHg was regarded as high blood pressure (HBP). Their heights and weights were measured and their body mass indices (BMI) calculated using the standard formula of BMI = Weight in Kg/Height in m 2 ; BMI =30 Kg/m 2 was referred to as global obesity. Their waist circumferences (WC) were also measured and any value =102 cm for males and =88 cm for females was regarded as abdominal obesity. Results: The general prevalence of HBP in the rural community was 44.5. The prevalence of HBP increased as age increased and awareness about HBP was low (15.2). Females were more aware than the males. The prevalence of HBP was higher in males (49.3) compared with their female counterparts (42.3); whereas the females had a higher prevalence of all forms of obesity (abdominal: 36.2; global: 14.8) compared with the males (abdominal: 14.5; global: 10.1). Higher BMI was associated with higher systolic and diastolic BP values. Hypertensive participants had higher BMI and WC than those who had normal BP. Conclusion: The prevalence of both hypertension and obesity seems to be increasing in rural communities in Nigeria and thus; the available prevalence documented in previous studies for rural communities may no longer represent the current trend. Awareness of the participants about these major cardiovascular risk factors is still very low. Higher BMI was associated with higher values of both systolic and diastolic BP
