Abstract

Type 1 diabetic patients (T1DM) experience a higher cardiovascular disease and mortality risk than controls. We investigated whether visceral adipose tissue (VAT) contributes to coronary artery calcifications (CAC) and cardiac dysfunction in T1DM. A cross-sectional study of 118 T1DM patients without a history of cardiovascular disease (men/women: 68/50, age 46±12years, HbA1c 7.6±0.9%, BMI 25.8±4.1kg/m2) was conducted. CAC and VAT were measured using a CT scan. CAC was scored using the Agatston method. Cardiac functional abnormalities were assessed by echocardiography. CAC scored ≥10 in 42% of patients. Systolic function was normal in all, but diastolic dysfunction was present in 75%. Forty-six percent had VAT≥100cm2. CAC score≥10 occurred more often in subjects with VAT≥100cm2 (54% vs 31%; p=0.01). Age (OR=1.10; p<0.0001), diabetes duration (OR=1.10; p=0.008), gender (OR=4.28; p=0.016), LDL-cholesterol (OR=1.03; p=0.009) and metabolic syndrome (OR=5.79; p=0.005) were independently associated with a CACS≥10. Subjects with CACS≥10 were more prone to have diastolic dysfunction (84 vs 54%; p=0.03). Factors independently associated with diastolic dysfunction were age (OR=1.11; p=0.002), waist circumference (OR=1.10; p=0.016) and VAT...Continue Reading

Cardiovascular Diseases: Risk Factors

Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.

Cardiovascular Inflammation

Inflammation plays a significant role in the development of cardiovascular diseases, an understanding of these endogenous processes is critical for evaluating the risks and potential treatment strategies. Discover the latest research on cardiovascular inflammation here.

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.
