“…It is undoubtedly the fifth dimension in cardiovascular examination after inspection, palpation, percussion, and auscultation 1. It gives relevant morphological and hemodynamic information which often guides the management of cardiac patients 2,3. The field of echocardiography is rapidly expanding from the use of M-mode in the 1950s to three-dimensional, Doppler, and transesophageal echocardiography in present day cardiology 4.…”

BackgroundEchocardiography remains a key noninvasive cardiac investigative tool in the management of patients, especially in a developing economy like Nigeria. In this study, we investigated the indications for transthoracic echocardiography and spectrum of cardiac disease found in patients referred to our cardiac unit for echocardiography.MethodsA prospective two-dimensional, pulsed, continuous, and color-flow Doppler echocardiographic evaluation was done using the transthoracic approach in 2501 patients over an eight-year period. Univariate data analysis was performed for mean age, gender, clinical indications, and diagnoses.ResultsThe subject age range was less than 12 months to 97 years (mean 52.39 years). There were 1352 (54.06%) males and 1149 (45.94%) females. The most common indication for echocardiography was hypertension (52.1%) followed by congestive cardiac failure (13.9%). Others were for screening (6.1%), arrhythmias (5%), cerebrovascular disease (5%), chest pain (3.3%), chronic kidney disease (3.2%), congenital heart disease (2.6%), cardiomyopathy (1.8%), rheumatic heart disease (1.7%), diabetes mellitus (1.3%), thyrocardiac disease (1.2%), ischemic heart disease (1.2%), and pericardial disease (1.1%). The echocardiographic diagnosis was hypertensive heart disease in 59.4% of subjects and normal in 14.1%. Other echocardiographic diagnoses included rheumatic heart disease (3.1%), congenital heart disease (2.1%), cardiomyopathy (1.7%), pericardial disease (1.1%), and ischemic heart disease (0.1%).ConclusionHypertension and its cardiac complications is the most common echocardiographic indication and diagnosis at our unit.

“…It has been demonstrated that systolic and diastolic dysfunctions coexist in the majority of patients with congestive HF [4-7]. Echocardiography has become the noninvasive method of choice for the assessment of either systolic or diastolic left ventricular (LV) function [8], and echocardiographic findings are known to influence management decisions and outcomes [9]. …”

Relationship between clinically assessed heart failure severity and the Tei index in Nigerian patients

BackgroundThe Tei index is a Doppler-derived myocardial performance index. It is a measure of the combined systolic and diastolic myocardial performance of both the left and right ventricles. The incidence of heart failure (HF) is increasing globally, and its severity can be clinically assessed using the New York Heart Association (NYHA) functional classification and more objectively using echocardiographic assessment of systolic and diastolic functions. Thus, a measure of the combined systolic and diastolic myocardial performance could be a useful predictor of the severity of the clinical status of patients with HF.ResultsSeventy-five newly presenting patients with HF of NYHA class II to IV and 60 normal controls were consecutively recruited. Using conventional two-dimensional and Doppler echocardiography techniques, the left ventricular parameters assessed were the isovolumic relaxation time (IVRT), isovolumic contraction time (IVCT), ejection time (ET), ejection fraction (EF), and end-diastolic volume (EDV). The Tei index was determined using the formula IVCT + IVRT/ET. The mean Tei index of patients was significantly higher than that of controls (0.884 ± 0.321 vs. 0.842 ± 0.14; p < 0.001). The Tei index ranged from 0.33 to 1.94 in patients and from 0.56 to 1.24 in controls. The mean EF was lower in patients than in controls (50.47% ± 19.01% vs. 68.35% ± 7.75%; p = 0.001). The mean EDV was higher in patients than in controls (171.39 ± 100.96 vs. 94.15 ± 28.54; p < 0.001). Comparison of the mean Tei indices of patients with HF of NYHA classes II, III, and IV showed statistically significant differences among all three groups (p < 0.001).ConclusionsThe Tei index seems to be a clinically relevant indicator of cardiac function. It is reflective of the severity of HF as clinically assessed using the NYHA functional classification in patients with HF.
