Methods： 55 patients with chronic AF and 58 control patients in sinus rhythm were included into the study. Patients with acute heart failure （HF）, chronic inflammatory or neoplastic disease were excluded from the study. Circulating levels of CA-125 were assessed; all patients underwent clinical examination, assessment and medical records including demographic data, history of comorbid conditions, current use of cardiac medications, and the results of cardiac tests including electrocardiograms. Results： The mean age of the study sample was 53.2±6.5 years and 48% were men. Patients with sinus rhythm were significantly more likely to have lower heart rates, smaller dimensions of left atrium, and to be treated with aspirin. Coumadin, coumadin and digoxin were more often prescribed in patients with chronic AF. The CA-125 levels were significantly higher in patients with chronic AF than in patients in sinus rhythm （48.5±7.65 U/ml and 28.43±5.48 U/ml, P〈0.005）. An inverse relation was found between CA-125 levels and left ventricular ejection fraction （LVEF） （r=-0.48, P〈0.001）. CA-125 was significantly related to the left atrium （LA） diameter, left ventricular end-diastolic diameter （LVEDD）, left ventricular end-systolic diameter （LVESD） and brain natriuretic peptide （BNP）. There was no significant correlation between CA-125 and age. Conelusion： In subjects with chronic AF, CA-125 levels are increased; CA-125 was significantly related to the LA diameter, LVEDD, LVESD and BNP.展开更多

Methods Sixteen single chamber ICDs and 5 double chamber ICDs in 21 consecutive patients [ 17 males, 4 females; mean age, （ 36 ± 11） years ] with Brugada syndrome were involved. Fifteen patients with spontaneous or induced ventricular tachycardia/ventricular fibrillation （VT/VF） received the remedial and prophylactic ICD implantation. Six patients only with positive family history or syncope accepted the ICD implantation for prophylaxis. Results After a median follow-up of （22.3 ± 13. 4） months, all patients were alive. One patient was suspected with febrile syndrome due to endocarditis on the auricular face of the lead of defibrillator 18 months after 1CD implantation and disappearance of vegetation was found after receiving one-month antibiotic treatment. Nine appropriate ICD interventions took place in 3 individuals with documented spontaneous ventricular arrhythmias. Multivariable analysis suggested that occurrence of appropriate interventions was related to the spontaneous ventricular arrhythmias （ P 〈 0. 0001 ）. Eleven inappropriate ICD interventions occurred in 3 patients for atrial fibrillation or atrial flutter with rapid ventricular rate. Multivariable analysis suggested that occurrence of inappropriate interventions was related to documented spontaneous supraventricular arrhythmias （P 〈 O. 0062 ）. All appropriate interventions and inappropriate interventions occurred within six months after ICD implantation. Conclusion Appropriate interventions may associate to spontaneous ventricular arrhythmias before 1CD implantation in patients with Brugada syndrome. Patients may suffer from inappropriate ICD intervention for supraventricular arrhythmias with rapid ventricular rate when they had a history of supraventricular arrhythmias.展开更多

METHODS: 322 consecutive patients who had undergone isolated CABG were reviewed. Preoperative, intraoperative and postoperative data were collected. Patients were grouped according to whether AF appeared postoperatively. RESULTS: AF occurred in 75 patients (23.3%). Most cases of AF (85.6%) appeared on or before the third postoperative day. The mean age for patients with AF was 62.5 years compared with 56.7 years for patients without AF (P or = 65 years (OR 2.7; 95% CI 1.5 to 5.1), lesions in the right coronary artery (OR 2.5; 95% CI 1.4 to 4.5), and early postoperative withdrawal of beta blocker (OR 3.9; 95% CI 2.1 to 7.7). CONCLUSIONS: AF remains the most common complication after CABG. Age and lesions in the right coronary artery can influence the incidence of AF, and beta blocker and magnesium may be the most economical and effective prevention for AF early after CABG.展开更多
