Concentric left ventricular remodelling is associated with subclinical systolic dysfunction in patients with psoriatic arthritis

Objectives Subclinical left ventricular (LV) abnormalities have been reported in echocardiographic studies of patients with psoriatic arthritis (PsA). Left ventricular systolic dysfunction (LVSD) often coexists with concentric LV remodelling, an unfavourable prognostic factor that is commonly found in patients at high cardiovascular risk. However, it is unclear whether PsA is associated with concentric LV remodelling. This cross-sectional study assesses the prevalence of and factors associated with concentric LV remodelling in a cohort of patients with PsA, and tests the hypothesis that concentric LV remodelling is a major determinant of LVSD in PsA. Method We evaluated 101 adults attending an outpatient clinic with PsA diagnosed according to the ClASsification criteria for Psoriatic ARthritis (CASPAR). All patients were free of cardiovascular disease. Patients with PsA were compared with 101 controls matched for age, gender, body mass index, hypertension, and diabetes. Echocardiography was performed: concentric LV remodelling was defined if the relative wall thickness was > 0.43; stress-corrected mid-wall shortening was used as an index of LVSD and considered impaired if Results Concentric LV remodelling was found in 58% of patients with PsA and 18% of controls (p < 0.001). LVSD was found in a significantly higher proportion of patients with PsA (56%, p < 0.001) than controls. The presence of PsA yielded a 10-fold higher probability of having LVSD [odds ratio (OR) 9.6, 95% confidence interval (CI) 4.2-21.9, p < 0.0001]. In patients with PsA, concentric LV remodelling increased the risk of LVSD four-fold (OR 3.7, 95% CI 1.3-10.2, p = 0.013). Conclusion Most asymptomatic patients with PsA have concentric LV remodelling, which is closely associated with subclinical LVSD

Effects of linagliptin on left ventricular DYsfunction in patients with type 2 DiAbetes and concentric left ventricular geometry: results of the DYDA 2 trial

Aims: To evaluate the effect of linagliptin on left ventricular systolic function beyond glycaemic control in type 2 diabetes mellitus. Methods and results: A multicentre, randomised, double-blind, placebo controlled, parallel-group study, was performed (the DYDA 2 trial). Individuals with type 2 diabetes mellitus and asymptomatic impaired left ventricular systolic function were randomly allocated in a 1:1 ratio to receive for 48 weeks either linagliptin 5 mg daily or placebo, in addition to their diabetes therapy. Eligibility criteria were age 40 years and older, haemoglobin A1c 8.0% or less (≤64 mmol/mol), no history of cardiac disease, concentric left ventricular geometry (relative wall thickness ≥0.42), impaired left ventricular systolic function defined as midwall fractional shortening 15% or less at baseline echocardiography. The primary end point was the modification of midwall fractional shortening over time. The main secondary objectives were changes in diastolic and/or in longitudinal left ventricular systolic function as measured by tissue Doppler echocardiography. One hundred and eighty-eight patients were enrolled, predominantly men with typical insulin-resistance comorbidities. At baseline, mean midwall fractional shortening was 13.3%±2.5. At final evaluation, 88 linagliptin patients and 86 placebo patients were compared: midwall fractional shortening increased from 13.29 to 13.82 (+4.1%) in the linagliptin group, from 13.58 to 13.84 in the placebo group (+1.8%, analysis of covariance P = 0.86), corresponding to a 2.3-fold higher increase in linagliptin than the placebo group, although non-statistically significant. Also, changes in diastolic and longitudinal left ventricular systolic function did not differ between the groups. Serious adverse events or linagliptin/placebo permanent discontinuation occurred in very few cases and in the same percentage between the groups. Conclusions: In the DYDA 2 patients the addition of linagliptin to stable diabetes therapy was safe and provided a modest non-significant increase in left ventricular systolic function measured as midwall fractional shortening.

Traditional cardiovascular risk factors or inflammation: Which factors accelerate atherosclerosis in arthritis patients?

Patients with chronic inflammatory arthritis experience an increased incidence of cardiovascular (CV) events. In addition to visualizing atherosclerotic plaques, ultrasound examinations (USs) of the carotid arteries permit the measurement of subclinical markers of atherosclerosis, such as intima-media thickness (cIMT) and carotid segmental distensibility (cDC). The aims of the study were to identify the determinants of atherosclerosis acceleration (plaques, cIMT and cDC) in a sample of patients suffering from chronic arthritis and to compare these patients with a control group of people with 641 traditional risk factor (TRF) for CV disease

Effects of Dipeptidyl Peptidase-4 Inhibitor Linagliptin on Left Ventricular Dysfunction in Patients with Type 2 Diabetes and Concentric Left Ventricular Geometry (the DYDA 2™ Trial). Rationale, Design, and Baseline Characteristics of the Study Population

A multicentre, randomized, double-blind, placebo-controlled, parallel-group study aimed to define the potential positive effect of dipeptidyl peptidase-4 inhibition on left ventricular systolic function (LVSF) beyond glycemic control in type 2 diabetes mellitus (T2DM) (DYDA 2™ trial)
