摘要

<strong>Background:</strong><span style="font-family:Verdana;"> Heart failure is the commonest cardiovascular complication in type 2 diabetes mellitus. However, subclinical left ventricular dysfunction can’t be detected using 2D echocardiography which </span><span style="font-family:Verdana;">is </span><span style="font-family:;" "=""><span style="font-family:Verdana;">routinely used for cardiac evaluation of diabetic patients. We aimed to determine the prevalence and factors associated to left ventricular global longitudinal strain (LV GLS) impairment in type 2 diabetes Cameroonians patients. </span><b><span style="font-family:Verdana;">Methods:</span></b><span style="font-family:Verdana;"> We conducted a cross-sectional study from January 2019 to June 2019, including type 2 diabetes patients with preserved left ventricle ejection fraction. Clinical and echocardiographic data were collected, and LV GLS was assessed using speckle tracking technique, a value ≤</span></span><span style="font-family:Verdana;"> -</span><span style="font-family:;" "=""><span style="font-family:Verdana;">16% been considered as normal value. </span><b><span style="font-family:Verdana;">Results:</span></b><span style="font-family:Verdana;"> We recruited 95 patients, with a mean age of 57.4 ± 11.8 years old and median diabetes duration of 5 [2 </span></span><span style="font-family:Verdana;">-</span><span style="font-family:Verdana;"> 12] years. Echocardiographic evaluation found 56.3% of left ventricle remodelling, 51.6% of left ventricle diastolic dysfunction and mean left ventricle ejection of 63.3</span><span style="font-family:Verdana;">%</span><span style="font-family:Verdana;"> ± 6.6%. LV GLS impairment was present in 43.2% (95% CI: 32.6 </span><span style="font-family:Verdana;">-</span><span style="font-family:Verdana;"> 53.7) of the participants.
