| 1 | Simple hematological predictors of AF recurrence in patients undergoing atrial fibrillation ablation显示文摘Backgound Red cell distribution width(RDW) and neutrophil-to-lymphocyte ratio(NLR) are simple hematologic indices that have been used to predict adverse outcomes in different clinical settings. The aim of our study is to determine whether RDW and NLR can predict atrial fibrillation(AF) recurrence in patients undergoing AF ablation. Methods Consecutive patients, without known hematological disorders, who underwent AF catheter ablation between January 2014 and April 2017 were enrolled into this study. Blood samples were taken one day before and five hours after the ablation procedure. Results A total of 346 patients(224 males(65%), mean age: 59 ± 11 years old) were included. After a mean follow up of 26.2 ± 12.1 months, 80(23.1%) patients experienced late AF recurrence(defined as any recurrence after the blanking period of three months), while 97(28%) patients experienced early AF recurrence during the blanking period. Univariate analysis showed that early arrhythmia recurrence, type of AF and NLR after the procedure were significantly associated with late AF recurrence, while early arrhythmia recurrence and NLR remained significant in multivariate analysis. RDW was not associated with late AF recurrence. None of the parameters above predicted early arrhythmia recurrence. Conclusions Simple and inexpensive hematological indices such as NLR should be evaluated for their ability to predict AF recurrence in patients undergoing catheter ablation in larger prospective studies. | George Bazoukis Konstantinos P Letsas Konstantinos Vlachos Athanasios Saplaouras Dimitrios Asvestas Konstantinos Tyrovolas Aikaterini Rokiza Eirini Pagkalidou Gary Tse Stavros Stavrakis Antonios Sideris Michael Efremidis | 2019 | Journal of Geriatric Cardiology2019，16，9： | 4 |
| 2 | Headache:An unusual presentation of acute myocardial infraction显示文摘Acute myocardial infarction should be diagnosed as early as possible for the appropriate management to salvage ischemic myocardium. Accurate diagnosis is typically based on the typical symptoms of angina. Headache is an unusual symptom in patients with acute myocardial infraction. We report a patient with ST-segment elevation acute myocardial infarction who presented to the emergency department complaining of severe occipital headache without chest discomfort. | Dimitrios Asvestas Konstantinos Vlachos Anastasios Salachas Konstantinos P Letsas Antonios Sideris | 2014 | World Journal of Cardiology2014，6，6： | 3 |

| 11 | Catheter ablation of persistent atrial fibrillation:The importance of substrate modification显示文摘Accumulating data have shown that elimination of atrial fibrillation(AF) sources should be the goal in persistent AF ablation. Pulmonary vein isolation, linear lesions and complex fractionated atrial electrograms(CFAEs) ablation have shown limited efficacy in patients with persistent AF. A combined approach using voltage, CFAEs and dominant frequency(DF) mapping may be helpful for the identification of AF sources and subsequent focal substrate modification. The fibrillatory activity is maintained by intramural reentry centered on fibrotic patches. Voltage mapping may assist in the identification of fibrotic areas. Stable rotors display the higher DF and possibly drive AF. Furthermore, the single rotor is usually consistent with organized AF electrograms without fractionation. It is therefore quite possible that rotors are located at relatively 'healthy islands' within the patchy fibrosis. This is supported by the fact that high DF sites have been negatively correlated to the amount of fibrosis. CFAEs are located in areas adjacent to high DF. In conclusion, patchy fibrotic areas displaying the maximum DF along with high organization index and the lower fractionation index are potential targets of ablation. Prospective studies are required to validate the efficacy of substrate modification in left atrial ablation outcomes. | Konstantinos P Letsas Michael Efremidis Nikolaos P Sgouros Konstantinos Vlachos Dimitrios Asvestas Antonios Sideris | 2015 | World Journal of Cardiology2015，7，3： | 1 |
