Background: Lone atrial fibrillation (AF) has been suggested to have a favorable long-term prognosis. Significant interest has been directed at factors predicting arrhythmia progression, and the HATCH score (hypertension, age ≥ 75 years, transient ischemic attack or stroke [2 points], COPD, and heart failure [2 points]) recently has been proposed as a predictive score for AF progression. We investigated long-term outcomes in a large cohort of newly diagnosed lone AF and whether progression from paroxysmal to permanent AF confers an adverse impact on outcomes, including stroke and thromboembolism. Methods: The study was an observational cohort of 346 patients with newly diagnosed lone AF with a mean follow-up of 12.1 ± 7.3 years. Results: Baseline paroxysmal AF was confirmed in 242 patients, and of these, 65 (26.9%) subsequently experienced progression to permanent AF. Older age and development of congestive heart failure during follow-up were the multivariate predictors of AF progression (both P<.01), which was documented in 19.8% of patients with a HATCH score of 0 vs 63.2% with a score of 2 ( P<.001), although the predictive validity of the HATCH score per se was modest (C statistic, 0.6). The annual rate of thromboembolism and heart failure during follow-up were low (0.4% each), and five patients (1.4%) died. AF progression, development of cardiac diseases, and older age were multivariate predictors of adverse outcomes, including thromboembolism (all P<.05). Baseline CHADS2 (congestive heart failure, hypertension, age ≥75, diabetes mellitus, prior stroke or transient ischemic attack) score was not predictive for thromboembolism (C statistic, 0.50; 95% CI, 0.31-0.69). Conclusions: This 12-year follow-up study provides confirmatory evidence of a generally favorable prognosis of lone AF, but adverse outcomes (including stroke and thromboembolism) are significantly infl uenced by age and the (new) development of underlying heart disease. Arrhythmia progression in lone AF is a marker of increased risk for adverse cardiovascular events. © 2012 American College of Chest Physicians.

Coronary bifurcation lesions are accounted in about 20% of all percutaneous coronary interventions and despite all-round improvements in their treatment are still perceived as complex lesion subset in interventional cardiology. Treatment of bifurcations, being technically demanding primarily due to the unique bifurcation anatomy, is related to lower procedural success rate and increased rates of long-term adverse cardiac events. According to published data, provisional approach remains a default strategy for majority of bifurcation PCI, but when perfected, two-stent bifurcation techniques can also yield good clinical outcomes. In this paper, we summarize in stepwise fashion technical aspects of optimal, evidencebased bifurcation treatment aiming to accomplish best procedural results and favorable long-term prognosis. © 2018 EDIZIONI MINERVA MEDICA.

Background: The COMET-CTO trial was a randomized prospective study that assessed long-term follow-up in patients with chronic total occlusion (CTO) in coronary arteries treated with percutaneous coronary intervention (PCI) or with optimal medical therapy (OMT). During the 9-month follow-up, the incidence of major adverse cardiac events (MACE) did not differ between the two groups; no death or myocardial infarction (MI) was observed. There was a significant difference in quality of life (QoL), assessed by the Seattle Angina Questionnaire (SAQ), in favor of the PCI group. Here we report long-term follow-up results (56 ± 12 months). Methods: Between October 2015 and May 2017, a total of 100 patients with CTO were randomized into two groups of 50 patients: PCI CTO or OMT group. The primary endpoint of the current study was the incidence of MACE defined as cardiac death, MI, and revascularization [PCI or coronary artery bypass graft (CABG)]. As the secondary exploratory outcome, we analyzed all the cause-mortality rate. Results: Out of 100 randomized patients, 92 were available for long-term follow-up (44 in the PCI group and 48 in the OMT group). The incidence of MACE did not differ significantly between the two groups (p = 0.363). Individual components of MACE were distributed, respectively: cardiac death (OMT vs. PCI group, 6 vs. 3, p = 0.489), MI (OMT vs. PCI group, 1 vs. 0, p = 1), and revascularization (PCI: OMT vs. PCI group, 2 vs. 2, p = 1; CABG: OMT vs. PCI group, 1 vs. 1, p = 1). There was no significant difference between the two groups regarding the individual component of MACE. Six patients died from non-cardiac causes [five deaths were reported in the OMT group and one death in the PCI group (p = 0.206)]. Kaplan-Meier survival curves for MACE did not differ significantly between the study groups (log-rank 0.804, p = 0.370). Regarding the secondary exploratory outcome, a total of 15 patients died at 56 ± 12 months (11 in the OMT and 4 in the PCI group) (p = 0.093). The Kaplan-Meier survival curves for all-cause mortality rates did not differ significantly between the two groups (log rank 3.404, p = 0.065). There were no statistically significant differences between OMT and PCI groups in all five SAQ domains. There was a significant improvement in three SAQ domains in the PCI group: PL (p < 0.001), AF (p = 0.007), and QoL (p = 0.001). Conclusion: After 56 ± 12 months of follow-up, the incidence of MACE, as well as QoL measured by SAQ, did not differ significantly between the PCI and OMT groups.

Background: Mitral annular calcification (MAC) has been suggested as a reliable, time-averaged marker of atherosclerosis and is associated with coronary artery disease, heart failure, ischemic stroke, and increased mortality. Data on the relationship between MAC and cardiovascular morbidity and mortality in atrial fibrillation (AF) are sparse, with the exception of the relationship between MAC and stroke. We investigated the association of MAC with cardiovascular morbidity, stroke, cardiovascular mortality, and all-cause death in a cohort of middle-aged patients with AF with a mean 10-year follow-up. Methods: This was an observational study of patients with nonvalvular AF between 1992 and 2007. Results: Of 1,056 patients, 33 (3.1%) had MAC; they were more likely to be older and female and to have a dilated left atrium, reduced left ventricular ejection fraction, permanent AF, hypertension, and/or diabetes mellitus (all P < .05). Total follow-up was 10,418.5 years (mean, 9.9 ± 5.9 years), and the mean age was 52.7 ± 12.2 years. In univariate analysis, MAC was associated with all-cause death, cardiovascular death, stroke, new cardiac morbidity (all P < .05), and the composite end point of ischemic stroke, myocardial infarction (MI), and all-cause death (P < .001). In multivariate analyses, MAC was related to all-cause death (hazard ratio [HR], 4.3; 95% CI, 1.8-10.0; P < .001), cardiovascular death (HR, 3.5; 95% CI, 1.2-10.4; P = .025), the composite end point (HR, 2.1; 95% CI, 1.0-4.3; P = .048), and new cardiac morbidity (HR, 2.4; 95% CI, 1.3-4.5; P = .005). There was no significant relationship between MAC and stroke or MI in the multivariate analyses. Conclusions: MAC is associated with increased cardiovascular morbidity, cardiovascular mortality, and all-cause mortality of patients with AF. MAC should be acknowledged as a marker of increased cardiovascular risk in middle-aged patients with AF. © 2011 American College of Chest Physicians.

Objective To investigate the relationship between inhospital bleeding as defined by Bleeding Academic Research Consortium (BARC) consensus classification and short-term and long-term mortality in unselected patients admitted for primary percutaneous coronary intervention (PCI). Methods We analysed data of all consecutive patients with ST segment elevation myocardial infarction (STEMI) admitted for primary PCI, enrolled in a prospective registry of a high volume centre. The BARC-defined bleeding events were reconstructed from the detailed, prospectively collected clinical data. The primary outcome was mortality at 1 year. Results Of the 1808 patients with STEMI admitted for primary PCI, 115 (6.4%) experienced a BARC type ≥2 bleeding. As the BARC bleeding severity worsened, there was a gradient of increasing rates of 1-year death. The 1-year mortality rate increased from 11.5% with BARC 0+1 type to 43.5% with BARC type 3b bleeding. After multivariable adjustment for demographic and clinical characteristics of patients, the independent predictors of 1-year death were BARC type 3a (HR 1.99; 95% CI 1.16 to 3.40, p=0.012) and BARC type 3b bleeding (HR 3.22; 95% CI 1.67 to 6.20, p<0.0001). Conclusions The present study demonstrated that bleeding events defined according to the BARC classification hierarchically correlate with 1-year mortality after admission for primary PCI. The strongest predictor of 1-year mortality is the BARC type 3b bleeding.

The aim of this randomized prospective study was to evaluate the quality of life (QoL) using the “Seattle Angina Questionnaire” (SAQ) in patients with chronic total occlusion (CTO) in coronary arteries treated with either percutaneous coronary intervention (PCI) or optimal medical therapy (OMT), or only with OMT. The potential benefits of recanalization of CTO by PCI have been controversial because of the scarcity of randomized controlled trials. A total of 100 patients with CTO were randomized (1:1) prospectively into the PCI CTO or the OMT group (50 patients in each group). There were no baseline differences in the SAQ scores between the groups, except for physical limitation scores (P = 0.03). During the mean follow-up (FUP) of 275 ± 88 days, patients in the PCI group reported less physical activity limitations (72.7 ± 21.3 versus 60.5 ± 27, P = 0.014), less frequent angina episodes (89.8 ± 17.6 versus 76.8 ± 27.1, P = 0.006), better QoL (79.9 ± 22.7 versus 62.5 ± 25.5, P = 0.001), greater treatment satisfaction (91.2 ± 13.6 versus 81.4 ± 18.4, P = 0.003), and borderline differences in angina stability (61.2 ± 26.5 versus 51.0 ± 23.7, P = 0.046) compared to patients in the OMT group. There were no significant differences in SAQ scores in the OMT group at baseline and during the FUP. There was a statistically significant increase in all five domains in the PCI group. Symptoms and QoL measured by the SAQ were significantly improved after CTO PCI compared to OMT alone. © 2021, International Heart Journal Association. All rights reserved.

Aims Treatment burden (TB) refers to self-perceived cumulative work patients do to manage their health. Using validated tools, TB has been documented in several chronic conditions, but not atrial fibrillation (AF). We measured TB and analysed its determinants and impact on quality of life (QoL) in an AF cohort. Methods A single-centre study prospectively included consecutive adult AF patients and non-AF controls managed from 1 and results April to 21 June 2019, who voluntarily and anonymously answered the TB questionnaire (TBQ) and 5-item EQ-5D QoL questionnaire; TB was calculated as a sum of TBQ points (maximum 170) and expressed as proportion of the maximum value. Of 514 participants, 331 (64.4%) had AF. The mean self-reported TB was 27.6% among AF patients and 24.3% among controls, P = 0.011. The mean TB was significantly higher in patients taking vitamin K antagonists (VKAs) vs. those taking non-VKA antagonist oral anticoagulants (NOAC; 29.5% vs. 24.7%, P = 0.006). The highest item-specific TB was reported for healthcare system organization-related items (e.g. visit appointment), diet, and physical activity modifications. On multivariable analyses, female sex, younger age, and permanent AF were associated with a higher TB, whereas NOACs and electrical AF cardioversion exhibited an inverse association; TB was an independent predictor of decreased QoL (all P < 0.05). Conclusion Our study provided clinically relevant insights into self-perceived TB among AF patients. Approximately one in four patients with AF have a high TB. Specific AF treatments and optimization of healthcare system-required patient activities may reduce the self-perceived TB in AF patients. © The Author(s) 2020.
