A meta-analysis for efficacy and safety evaluation of transcatheter left atrial appendage occlusion in patients with nonvalvular atrial fibrillation
Objectives: This meta-analysis was conducted to evaluate the efficacy and safety of transcatheter left atrial appendage (LAA) occlusion in patients with nonvalvular atrial fibrillation. Methods: The randomized controlled trials (RCT) or observational studies with any transcatheter LAA occlusion devices were searched in PubMed, Embase, and Cochrane library from inception to November 2015. The incidence rates from individual studies were combined to evaluate the procedural efficacy and safety, including all-cause death, cardiac/neurological death, stroke, transient ischemic attack (TIA), thrombosis, hemorrhagic complication...

The safety and efficacy of oral anticoagulants with dual versus single antiplatelet therapy in patients after percutaneous coronary intervention: A meta-analysis
Conclusion: In patients on OAC undergoing PCI with stent implantation, compared with DT, TT shows equal effectiveness in terms of MACE, stroke, all-cause mortality, and stent thrombosis and lower risks of myocardial infarction and major bleeding. However, similar efficacy and safety outcomes were observed between the TT group and the OAC along with clopidogrel group.

Effect of atrial fibrillation in Asian patients undergoing percutaneous coronary intervention with drug-eluting stents for stable coronary artery disease: Results from a Korean nationwide study
Although the prevalence of atrial fibrillation (AF) and percutaneous coronary intervention (PCI) are increasing in Asia, there is a paucity of data concerning the effect of AF in Asian patients undergoing PCI with drug-eluting stents (DESs). Furthermore, the majority of previous studies investigating the effect of AF on prognosis following PCI have exclusively evaluated patients with myocardial infarction (MI). We aimed to evaluate the effect of AF on clinical outcomes of Asian patients undergoing PCI with DES for coronary artery disease (CAD) excluding acute MI. From national health insurance claims data in South Korea, ...

Long-term efficacy after closure of patent foramen ovale for ischemic neurological events in young adults: A systematic review and meta-analysis
Background: The efficacy of patent foramen ovale (PFO) closure remains controversial, and it is unclear which patient groups are best benefited. We performed this meta-analysis to clarify the efficacy of PFO closure of younger patients for prevention of recurrent ischemic neurological events. Methods: We systematically searched for studies of PFO closure for younger patients under the age of 55, and pooled available data on PFO closure of younger vs older patients and on PFO closure of younger patients vs medical therapy. The primary endpoints were the composite outcome of recurrent ischemic neurological events [strok...

Prognostic value of CHADS2 and CHA2DS2-VASc scores for post-discharge outcomes in patients with acute coronary syndrome undergoing percutaneous coronary intervention
This study aimed to investigate the association of CHADS2 and CHA2DS2-VASc scores with CV outcomes in such patients. We included a total of 915 ACS patients undergoing PCI in this study. CHADS2 and CHA2DS2-VASc scores were calculated from data collected before discharge. The primary endpoint was defined as a composite of major adverse CV events (MACE) including overall death, nonfatal stroke, nonfatal myocardial infarction (MI) and unplanned repeat revascularization. We assessed MACE's relationship to CHADS2 and CHA2DS2-VASc scores using Cox proportional-hazard regression analyses. Mean follow-up duration was 918 days. M...

Effects of corticosteroids on new-onset atrial fibrillation after cardiac surgery: A meta-analysis of randomized controlled trials
Conclusion: Our review suggests that the efficacy of corticosteroid might be beneficial to POAF development in patients undergoing cardiac surgery. The strength of this association remains uncertain because of statistical and clinical heterogeneity among the included studies.

Intracardiac thrombus in a patient with mitral bioprosthesis and atrial fibrillation treated with direct oral anticoaugulant: A case report
Rationale: Atrial fibrillation (AF) is the most common cardiac arrhythmia and is associated with increased morbidity, especially stroke and heart failure. There is also increasing awareness that atrial fibrillation is a major cause of embolic events which in 75% of cases are complicated by cerebrovascular accidents. Patient concerns: A 50-year-old woman with mitral bioprosthesis under warfarin for nonvalvular atrial fibrillation was referred to our Coronary Intensive Care Unit due to acute myocardial infarction without evidence of significant coronary artery stenosis. Diagnoses: Cardiovascular examination...

A meta-analysis of the association of atrial septal abnormalities and atrial vulnerability
Conclusions: Atrial septal abnormalities can increase the risk of atrial vulnerability, and atrial arrhythmia caused by atrial septal abnormalities may be one of the mechanisms of CS.

Predictors of hemorrhagic complications after intravenous thrombolysis in acute cerebral infarction patients: A single-center study of 391 cases
This study aimed to analyze the risk factors of hemorrhagic complications after intravenous thrombolysis using Urokinase in acute cerebral infarction (ACI) patients. Total 391 consecutive ACI patients were enrolled and divided into 2 groups: the hemorrhagic complications group and the non-hemorrhagic complications group. The related data were collected and analyzed. Univariate analysis showed significant differences in prothrombin time, atrial fibrillation (AF), Mean platelet volume, large platelet ratio (L-PLR), triglyceride (TG), Lactate dehydrogenase, alanine aminotransferase (ALT), high-density lipoprotein, and b...

The Prognostic Effects of Ventricular Heart Rate Among Patients With Permanent Atrial Fibrillation With and Without Coronary Artery Disease: A Multicenter Prospective Observational Study
This study aimed to assess the prognostic effects of ventricular heart rate in patients with permanent AF (permAF) and CAD. We performed a multicenter, prospective, observational study of patients with AF in China. Patients≥18 years old with permAF were included and divided into a CAD group and a non-CAD group. All patients underwent 1 year of follow-up. The primary outcome was total mortality. Cox proportional hazard models were used to evaluate the relationship between risk factors and the survival rate in the study population. A total of 852 patients (69.1±12.7 years old, 43.3% male, 44.7% with CAD) were included in ...

“Sudden Drop” in Blood Pressure is Associated With Recanalization After Thrombolysis
Abstract: We aim to investigate whether the phenomenon of “sudden drop” in blood pressure (BP) within the first 2 hours is associated with vessel recanalization. We retrospectively examined clinical and imaging data from a consecutive series of patients with stroke with large vessel occlusion treated with intravenous thrombolysis (IVT). BP was monitored every 15 minutes during the first 2 hours, then every 30 minutes for 6 hours, and then every hour for 16 hours. We observed the phenomenon of “sudden drop” in systolic BP (≥20 mm Hg) in 82 (50.9%) patients in the first 2 hours and vessel recanalization in 87 (54...

Association of Increased Epicardial Adipose Tissue Thickness With Adverse Cardiovascular Outcomes in Patients With Atrial Fibrillation
This study was conducted to analyze the ability of EAT thickness in predicting adverse cardiovascular (CV) events in AF. In 190 persistent AF patients, we performed a comprehensive transthoracic echocardiographic examination with assessment of EAT thickness. The definition of CV events included CV mortality, hospitalization for heart failure, myocardial infarction, and stroke. There were 69 CV events including 19 CV deaths, 32 hospitalizations for heart failure, 3 myocardial infarctions, and 15 strokes during a mean follow-up of 29 (25th–75th percentile: 17–36) months. The multivariable analysis demonstrates that chr...

Digoxin Use and Adverse Outcomes in Patients With Atrial Fibrillation
Abstract: Digoxin has long been used for rate control in atrial fibrillation (AF); its safety remains controversial. We performed a literature search using MEDLINE (source PubMed, January 1, 1966, to July 31, 2015) and EMBASE (January 1, 1980, to July 31, 2015) with no restrictions. Studies that reported relative risk (RR) estimates with 95% confidence intervals (CIs) for the associations of interest were included. Pooled effect estimates were obtained by using random-effects meta-analysis. Twenty-two studies involving 586,594 patients were identified. Patients taking digoxin, as compared with those who took no digoxin, ...
