These findings suggest that comprehensive risk assessments and the aim of reaching a low-risk profile are valid in PAH.

C ardiovascular disease is a leading mortality cause, which, despite a recent decline, still contributes to 4 million deaths per year, that is, almost half of all deaths in Europe, whereof ≈30% occurred at <65 years of age. 1It contributes to 22% of all disability-adjusted life-years lost in the European Union and a hospital discharge rate of 2400/100 000 inhabitants.2 Although traditional risk factors are behind a substantial proportion of cardiovascular disease, other factors are important.3 Chronic inflammation accelerates the progress of atherosclerosis, and inflammatory activation increases the risk for plaque rupture leading to acute coronary syndromes. 4,5 Editorial see p 549 Clinical Perspective on p 583Periodontal diseases are inflammatory conditions ranging from gingivitis to severe periodontitis, the latter with a prevalence of 9% in the western European population. 6 The prevalence is age dependent as exemplified by a survey from the United States where it increased from 11% in the age group 50 to 65 years to 20% among those >75 years. 7 The disease, which is diagnosed by clinical and radiographic examination, 8 is a chronic tissuedestructive inflammatory state, predominantly induced by Gramnegative bacteria colonizing the gingival crevice. 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 62±8), 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 (≈100 variables). Statistical comparisons included the Student pairwise t test and the McNemar test in 2×2 contingency tables. Contingency tables exceeding 2×2 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 confoundin...

Recent reports from worldwide pulmonary hypertension registries show a new demographic picture for patients with idiopathic pulmonary arterial hypertension (IPAH), with an increasing prevalence among the elderly.We aimed to investigate the effects of age and comorbidity on risk stratification and outcome of patients with incident IPAH.The study population (n=264) was categorised into four age groups: 18-45, 46-64, 65-74 and ≥75 years. Individual risk profiles were determined according to a risk assessment instrument, based on the European Society of Cardiology and the European Respiratory Society guidelines. The change in risk group from baseline to follow-up (median 5 months) and survival were compared across age groups. In the two youngest age groups, a significant number of patients improved (18-45 years, Z= -4.613, p<0.001; 46-64 years, Z= -2.125, p=0.034), but no significant improvement was found in the older patient groups. 5-year survival was highest in patients aged 18-45 years (88%), while the survival rates were 63%, 56% and 36% for patients in the groups 46-64, 65-74 and ≥75 years, respectively (p<0.001). Ischaemic heart disease and kidney dysfunction independently predicted survival.These findings highlight the importance of age and specific comorbidities as prognostic markers of outcome in addition to established risk assessment algorithms.

The majority of the PAH and CTEPH patients were diagnosed at age >65 years, in functional class III-IV, and exhibiting several comorbidities. PAH survival in SPAHR was similar to other registers.

IntroductionSpouses play a crucial role, both physically and psychologically, for patients with pulmonary arterial hypertension (PAH) and chronic thromboembolic pulmonary hypertension (CTEPH). Our aim was to investigate the spouse's experiences when living with a partner diagnosed with PAH or CTEPH.MethodsWe used a qualitative interview study design based on open-ended questions analysed using qualitative content analysis.Results14 spouses were interviewed. Two categories that describe spouses' experiences of dealing with everyday life were identified: “Living in an insecure life situation” and “Providing and receiving information and support”. The experiences reported by the spouses were that their life situation was insecure, and that they had challenges in providing and receiving information and support. Most spouses also wanted and felt a need to be more involved in the care.ConclusionThe spouses were only partly satisfied with their life situation. To support the spouse's participation, the PAH/CTEPH team should encourage the patient to bring their spouse along, and offer them the opportunity to participate in the contacts with healthcare and provide information on an individual family perspective.

Background and ObjectiveMatrix metalloproteinase (MMP) -8, -9 and myeloperoxidase (MPO) are inflammatory mediators. The potential associations between MMP-8, -9, MPO and their abilities to reflect cardiovascular risk remains to be evaluated in saliva. The objective of this study was to investigate the levels and associations of salivary MMP-8, -9, MPO and tissue inhibitors of metalloproteinase (TIMP)-1 in myocardial infarction (MI) patients and controls with or without periodontitis.Materials and Methods200 patients with a first MI admitted to coronary care units in Sweden from May 2010 to December 2011 and 200 controls matched for age, gender, residential area and without previous MI were included. Dental examination and saliva sample collection was performed 6-10 weeks after the MI in patients and at baseline in controls. The biomarkers MMP -8, -9, MPO and TIMP-1 were analyzed by time-resolved immunofluorescence assay (IFMA), Western blot and Enzyme-Linked ImmunoSorbent Assay (ELISA).ResultsAfter compensation for gingivitis, gingival pockets and smoking, the mean salivary levels of MMP-8 (543 vs 440 ng/mL, p = 0.003) and MPO (1899 vs 1637 ng/mL, p = 0.02) were higher in non-MI subjects compared to MI patients. MMP-8, -9 and MPO correlated positively with clinical signs of gingival/periodontal inflammation while TIMP-1 correlated mainly negatively with these signs. The levels of latent and active forms of MMP-8 did not differ between the MI and non-MI groups. Additionally, MMP-8, MPO levels and MMP-8/TIMP-1 ratio were significantly higher in men compared to women with MI.ConclusionsThis study shows that salivary levels of the analyzed biomarkers are associated with periodontal status. However, these biomarkers could not differentiate between patients with or without a MI. These findings illustrate the importance to consider the influence of oral conditions when analyzing levels of inflammatory salivary biomarkers.
