- Aims: To investigate the association between glucose abnormalities and left ventricular (LV) function assessed by tissue Doppler imaging (TDI) in patients with previous history of myocardial infarction and without known diabetes mellitus. Patients and methods: In a cross-sectional study, 123 patients, aged 31-80 years, with a history of previous myocardial infarction and without known diabetes mellitus were examined with TDI echocardiography. A standard oral glucose test (OGTT) with 75 g of glucose was performed. Results: Two-hour plasma glucose were significantly and negatively associated with TDI parameters such as LV ejection time; early diastolic filling velocity (E'-v); ratio of the early to late diastolic filling velocity (E'/A') and positively associated with regional myocardial performance index (MPI) (P < 0.05). Left ventricular ejection time and MPI were significantly higher; E'/A' and E'-v were significantly lower in patients with disturbed glucose metabolism compared with patients with normal glucose tolerance (P < 0.01). These differences remain significant also when the patients with DM were excluded. Conclusions: The present study demonstrates that disturbed glucose metabolism is associated with more pronounced LV dysfunction using TDI in patients with myocardial infarction. These abnormalities in LV function were more common not only in subjects with diabetes, but also in patients with prediabetic condition, impaired glucose intolerance.

Carotid Vessel Wall Thickness and Echogenicity : In the ULSAM study
- 2008

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In this thesis the common carotid artery intima media thickness in nearly 500 elderly men is independently associated with insulin sensitivity, measured by the gold standard hyperinsulinemic euglycemic clamp test (paper 1), to both COX- and cytokine mediated inflammation independently of other markers of inflammation, oxidative stress and antioxidant status (paper 2) and also to the alleles of the apolipoprotein gene independently of lipid levels and cardiovascular risk factors (paper 3). The echogenicity of the carotid intima-media complex measured as grey scale median predicts mortality independently of common carotid artery intima-media thickness, prior cardiovascular disease and cardiovascular risk factors (paper 4).
