- Background: Cardiovascular disease is a serious complication in patients with dysglycaemia, defined as either type 2 diabetes or impaired glucose tolerance. Research focusing on the identification of potential markers for atherothrombotic disease in these subjects is warranted. The antiphospholipid syndrome is a common acquired prothrombotic condition, defined by a combination of thrombotic events and/or obstetric morbidity and positivity of specific antiphospholipid antibodies. Available information on antiphospholipid antibodies in dysglycaemia is scarce. Objective: This study investigates the association between antiphospholipid antibodies and dysglycaemia. Patients/Methods: The PAROKRANK (periodontitis and its relation to coronary artery disease) study included 805 patients, investigated 6-10 weeks after a first myocardial infarction, and 805 matched controls. Participants without known diabetes (91%) underwent an oral glucose tolerance test. Associations between antiphospholipid antibodies (anti-cardiolipin and anti-beta 2 glycoprotein-I IgG, IgM and IgA) and dysglycaemia were analysed. Results: In total, 137 (9%) subjects had previously known type 2 diabetes and 371 (23%) newly diagnosed dysglycaemia. Compared with the normoglycaemic participants, those with dysglycaemia had a higher proportion with first myocardial infarction (61% vs 45%,p < 0.0001) and were more often antiphospholipid antibody IgG positive (8% vs 5%;p = 0.013). HbA1c, fasting glucose and 2-h glucose were significantly associated to antiphospholipid antibody IgG. Odds ratios (ORs) were 1.04 (95% confidence interval [CI] 1.02-1.06), 1.14 (95% CI 1.00 - 1.27) and 1.12 (95% CI 1.04 - 1.21), respectively, after adjustments for age, gender and smoking. Conclusions: This study reports an association between antiphospholipid antibody IgG positivity and dysglycaemia. Further studies are needed to verify these findings and to investigate if antithrombotic therapy reduces vascular complications in antiphospholipid antibody positive subjects with dysglycaemia.

- Objectives. When a forward running pressure wave from the right ventricle reaches the narrow vessels in the pulmonary circulation, it is reflected as a backward running wave. We aimed to relate changes in right ventricular waveform reflection (RVWR) to changes in clinical variables in pulmonary arterial hypertension (PAH) patients. Design. Twenty-one PAH patients with RV waveform recordings from two sequential catheterisations at least 6 months apart were included. Six-minute walked distance (6MWD) and brain natriuretic peptide (BNP) level were also available. RVWR was defined as the pressure from the inflection point on the upstroke RV pressure wave to RV peak pressure'. Direction of change in RVWR, 6MWD and BNP was classified as (+) if increased and (-) if decreased. Spearman correlations were used to analyse the relation between changes. Pearson's correlation coefficient was used to analyse relation between RVWR and pulmonary vascular resistance (PVR). Results. The correlation between change in RVWR and 6MWD was -0.67 (p < 0.01) and between RVWR and BNP was -0.53 (p < 0.05). Actual RVWR and PVR correlated both at first (0.56, p < 0.001) and at second right heart catheterisation (0.45, p < 0.001). Conclusion. RVWR might have clinical implications indicating a change in clinical status and disease progression in patients with PAH.

- Background The relationship between periodontitis (PD) and cardiovascular disease is debated. PD is common in patients with cardiovascular disease. It has been postulated that PD could be causally related to the risk for cardiovascular disease, a hypothesis tested in the Periodontitis and Its Relation to Coronary Artery Disease (PAROKRANK) study. Methods and Results Eight hundred five patients (<75 years of age) with a first myocardial infarction (MI) and 805 age- (mean 628), sex- (male 81%), and area-matched controls without MI underwent standardized dental examination including panoramic x-ray. The periodontal status was defined as healthy (80% remaining bone) or as mild-moderate (from 79% to 66%) or severe PD (<66%). Great efforts were made to collect information on possibly related confounders (approximate to 100 variables). Statistical comparisons included the Student pairwise t test and the McNemar test in 2x2 contingency tables. Contingency tables exceeding 2x2 with ranked alternatives were tested by Wilcoxon signed rank test. Odds ratios (95% confidence intervals) were calculated by conditional logistic regression. PD was more common (43%) in patients than in controls (33%; P<0.001). There was an increased risk for MI among those with PD (odds ratio, 1.49; 95% confidence interval, 1.21-1.83), which remained significant (odds ratio, 1.28; 95% confidence interval, 1.03-1.60) after adjusting for variables that differed between patients and controls (smoking habits, diabetes mellitus, years of education, and marital status). Conclusions In this large case-control study of PD, verified by radiographic bone loss and with a careful consideration of potential confounders, the risk of a first MI was significantly increased in patients with PD even after adjustment for confounding factors. These findings strengthen the possibility of an independent relationship between PD and MI.
