Objectives The influence of the bleeding site on long-term survival after the primary percutaneous coronary intervention (PCI) is poorly understood. This study sought to investigate the relationship between in-hospital access site versus non-access site bleeding and very late mortality in unselected patients treated with primary PCI. Methods Data of the 2715 consecutive patients with ST-segment elevation myocardial infarction treated with primary PCI, enrolled in a prospective registry of a high volume tertiary centre, were analysed. Bleeding events were assessed according to the Bleeding Academic Research Consortium (BARC) criteria. The primary outcome was 4-year mortality. Results The BARC type ≥2 bleeding occurred in 171 patients (6.3%). Access site bleeding occurred in 3.8%, and non-access site bleeding in 2.5% of patients. Four-year mortality was significantly higher for patients with bleeding (BARC type ≥2) than in patients without bleeding (BARC type 0+1), (36.3% vs 16.2%, p<0.001). Patients with non-access site bleeding had higher 4 year mortality (50.7% vs 26.5%, p=0.001). After multivariable adjustment, BARC type ≥2 bleeding was the independent predictor of 4 year mortality (HR 2.01; 95% CI 1.49 to 2.71, p<0.001). Patients with a non-access site bleeding were at 2-fold higher risk of very late mortality than patients with an access site bleeding (HR 2.62; 1.78 to 3.86, p<0.001 vs HR 1.57; 1.03 to 2.38, p=0.034). Conclusions Both access and non-access site BARC type ≥2 bleeding is independently associated with a high risk of 4-year mortality after primary PCI. Patients with non-access site bleeding were at higher risk of late mortality than patients with access site bleeding. © 2019 Author(s) (or their employer(s)).

Atrial fibrillation (AF) commonly co-exists with heart failure (HF). The risk factors for and prognostic implications of incident HF development in patients with first-diagnosed AF and structurally normal hearts are poorly defined. In a cohort of patients with first-diagnosed AF and structurally normal hearts on baseline echocardiography, we investigated baseline risk factors for the development of incident HF and tested the hypothesis that incident HF was an independent predictor of adverse outcomes during a mean 10-year follow-up period. This was a registry-based, observational cohort study of 842 patients initially diagnosed between 1992 and 2007 (mean age 51.6 ± 12.4 years), whereby 83 (9.9%) developed HF. The linearized rate of incident HF was 0.97% [95% confidence interval (CI) 0.78-1.19%] per 100 patient-years. Baseline history of hypertension, diabetes mellitus, dilated left atrium, and low-normal LVEF (50-54%) were multivariable predictors of subsequent HF (all P < 0.05). HF development was significantly associated with increased number of hospitalizations, AF progression, any stroke/peripheral thrombo-embolism, ischaemic stroke, cardiovascular death, and all-cause mortality (all P < 0.001). Kaplan-Meier 10-year estimates of survival free of the composite endpoint of AF progression, thrombo-embolism, and mortality were significantly worse for AF patients with incident HF compared with those without HF (68.8%; 95% CI 64.7-72.9 vs. 25.9% 95% CI 15.7-36.1, P < 0.001). Underlying co-morbidities or subtle alterations such as mild left atrial dilatation or low-normal LVEF in the absence of overt underlying heart disease are baseline independent risk factors for incident HF during a long-term follow-up. Incident HF was an independent predictor of adverse outcomes in patients initially diagnosed with first-diagnosed AF and structurally normal hearts. These findings could facilitate the identification of AF patients at increased risk for adverse outcomes within the cohort perceived as being at 'low risk' given a structurally normal heart on echocardiography.
