Background Health-related quality of life (HRQoL) is impaired in patients with stable angina but patients often present with other forms of chest pain. The aim of this study was to compare the pre-diagnostic HRQoL in patients with suspected coronary artery disease (CAD) according to angina type, gender, and presence of obstructive CAD. Methods From the pilot study for the European DISCHARGE trial, we analysed data from 24 sites including 1263 patients (45.9% women, 61.1 ± 11.3 years) who were clinically referred for invasive coronary angiography (ICA; 617 patients) or coronary computed tomography angiography (CTA; 646 patients). Prior to the procedures, patients completed HRQoL questionnaires: the Short Form (SF)-12v2, the EuroQoL (EQ-5D-3 L) and the Hospital Anxiety and Depression Scale. Results Fifty-five percent of ICA and 35% of CTA patients had typical angina, 23 and 33% had atypical angina, 18 and 28% had non-anginal chest discomfort and 5 and 5% had other chest discomfort, respectively. Patients with typical angina had the poorest physical functioning compared to the other angina groups (SF-12 physical component score; 41.2 ± 8.8, 43.3 ± 9.1, 46.2 ± 9.0, 46.4 ± 11.4, respectively, all age and gender-adjusted p < 0.01), and highest anxiety levels (8.3 ± 4.1, 7.5 ± 4.1, 6.5 ± 4.0, 4.7 ± 4.5, respectively, all adjusted p < 0.01). On all other measures, patients with typical or atypical angina had lower HRQoL compared to the two other groups (all adjusted p < 0.05). HRQoL did not differ between patients with and without obstructive CAD while women had worse HRQoL compared with men, irrespective of age and angina type. Conclusions Prior to a diagnostic procedure for stable chest pain, HRQoL is associated with chest pain characteristics, but not with obstructive CAD, and is significantly lower in women.

Introduction:Interventional ablation has been demonstrated to represent an effective therapy in patients with atrial fibrillation (AF), leading to restoration and maintenance of sinus rhythm in the majority of cases. However, recurrence of AF is encountered in 35% to 40% of cases, and the causes for this frequent complication have not been elucidated so far.Material and methods:Here we present the study protocol of the FIBRO-RISK trial, a prospective, single-center, cohort study which aims to investigate the impact of inflammatory-mediated myocardial fibrosis on the risk of recurrence after successful catheter ablation of atrial fibrillation. The level of systemic inflammation in the pre-ablation and immediate post-ablation period will be assessed on the basis of serum levels of inflammatory biomarkers (hsCRP, matrix metalloproteases, interleukin-6), while the level of cardiac fibrosis will be determined based on cardiac magnetic resonance imaging associated with complex post-processing techniques for mapping myocardial fibrosis at the level of left atrium and left ventricle. At the same time, the amount of epicardial fat will serve as an indirect marker of localized inflammation and will be determined at different levels in the heart (surrounding left atrium, right atrium or the entire heart), while ventricular function will be assessed on the basis of serum levels of NT-proBNP prior to the procedure. All these parameters will be investigated in patients with successful ablation of AF, who will be divided into 2 groups: group 1 – patients who develop AF recurrence at 1-year, and group 2 – patients with no recurrence of AF at 1-year. In all patients, the following biomarkers will be determined: serum levels of inflammatory biomarkers and NT-proBNP at 24 hours and 1-year post procedure, the amount of myocardial fibrosis at the level of left atrium and left ventricle at baseline +/− 7 days, and the amount of epicardial fat surrounding left atrium, right atrium and the entire heart at baseline +/− 7 days.The primary endpoint of the study will be represented by the rate of AF recurrence at 1-year post ablation, documented by either ECG or Holter monitoring. The secondary endpoints of the study will consist in:the rate of re-hospitalization,the rate of survival without relapse, andthe rate of major adverse cardiovascular events (MACE rate, including cardiovascular death or stroke).In conclusion, FIBRO-RISK will be the first CMR-based study that will investigate the impact of inflammation-mediated myocardial fibrosis and ventricular remodeling on the risk of recurrence after successful ablation of AF, aiming to validate inflammatory biomarkers and myocardial fibrosis as predictors for AF recurrence.

Increased values of ICS, a new CTA marker of vascular calcification, are associated with a higher severity and complexity of PAD and a more depressed left ventricular function. High ICS values are also associated with increased i-IMT. Both can represent new surrogate markers of an increased atherosclerotic burden.
