Indications for echocardiography and confirmation rates of cardiovascular diseases: experience of a specialist cardiac outpatient clinic in Kumasi, Ghana

ABSTRACT

Background: Transthoracic echocardiography is a very helpful noninvasive cardiovascular imaging technique for the diagnosis and risk stratification in the management of patients with cardiovascular diseases. We aimed to review the clinical indications for transthoracic echocardiography and the confirmation rate of cardiovascular diseases by echocardiography at a specialist cardiac clinic in Ghana. Methods: Using a cross sectional study design, the echocardiography reports of all patients above the age of 15 who were assessed at the clinic were analyzed. Data on patient demographics, clinical history, clinical indication for echocardiography, and the echocardiographic findings were analyzed using version 25.0 of the Statistical Package for Social Sciences (SPSS). Results: A total of 594 participants were studied. The age range of participants was 15­96 years, with a mean (± standard deviation) age of 53.72 (± 17.25) years. There were more females (50.17%) than males (49.83%). Most (54.21%) of the participants had echocardiography for cardiac evaluation. Other indications included hypertension/hypertensive heart disease (HHD) (n = 131; 22.06%), heart failure (n = 69; 11.62%), chest pains (n = 12; 2.02%), and valvular heart disease (VHD) (n = 11; 1.85%). Three hundred and eight nine (70.30%) of the participants had their clinical diagnoses confirmed by echocardiography; echocardiographic confirmation rates for heart failure, VHD, and HHD were 92.75%, 90.91%, and 88.54%, respectively. Conclusion: Echocardiography showed high confirmation rates for our patients with heart failure, VHD, and HHD. Prompt usage of this noninvasive cardiovascular imaging for the initial evaluation of patients with cardiovascular diseases is highly recommended.
