Issue Date: | 7-Oct-2013 | Publication information: | Journal of Diabetes and Its Complications 2013; 28(1): 22-8 | Abstract: | The aims of this observational study were to determine the prevalence and predictors of an abnormal echocardiogram in adults with type 1 diabetes, and to assess the evolution of changes in a subset of subjects.Cardiac function and structure were prospectively investigated by comprehensive transthoracic echocardiographic techniques in asymptomatic adults with type 1 diabetes seen in the ambulatory care setting.We recruited 136 subjects (mean age 39 years, SD 14 years) with a median diabetes duration of 21 years [25(th), 75(th) interquartile range; 11, 29]. An abnormal echocardiogram was present in 29% of subjects; diastolic dysfunction in 69%, left ventricular hypertrophy in 38% and systolic dysfunction in 10%. The independent predictors of an abnormal echocardiogram were age, with a 9-fold increase in those ≥40 years (OR 9.40 [95% CI 2.68-33.04], P <0.0001), and increased body mass index (BMI), with a 17% increase in risk (P=0.04). A second echocardiogram was available in 65 subjects (3.8±1.7 years later). The results showed that one in five with a normal first study had developed an abnormal second study, mainly diastolic dysfunction, with age being the only independent predictor of progression (P=0.006).Subclinical echocardiographic abnormalities are common in asymptomatic type 1 diabetes adults, and changes are progressive. The addition of an echocardiogram to complication surveillance programs in those with type 1 diabetes aged ≥40 years may represent a cost-effective way to screen for, and aggressively treat, occult cardiac disease. | Gov't Doc #: | 24210987 | URI: | https://ahro.austin.org.au/austinjspui/handle/1/11936 | DOI: | 10.1016/j.jdiacomp.2013.09.013 | Journal: | Journal of diabetes and its complications | URL: | https://pubmed.ncbi.nlm.nih.gov/24210987 | Type: | Journal Article | Subjects: | Cardiac disease Diastolic dysfunction Echocardiography Left ventricular hypertrophy Type 1 diabetes mellitus Adult Cohort Studies Diabetes Mellitus, Type 1.complications.epidemiology.ultrasonography Diabetic Cardiomyopathies.epidemiology.etiology.ultrasonography Disease Progression Echocardiography.statistics & numerical data Female Heart Diseases.epidemiology.etiology.ultrasonography Humans Hypertrophy, Left Ventricular.epidemiology.etiology.ultrasonography Male Middle Aged Prevalence Prognosis Risk Factors Ventricular Dysfunction, Left.epidemiology.etiology.ultrasonography |
