BACKGROUND Acute anterior ST-segment elevation myocardial infarction (STEMI) is a life-threatening disease. Adverse cardiac events of acute anterior STEMI include cardiovascular death or worsening congestive heart failure. This study investigated the role of fragmented QRS complex (fQRS) in predicting insufficient ejection fraction (EF) recovery in acute anterior STEMI. METHODS Patients with acute anterior STEMI who received thrombolytic therapy were prospectively enrolled in this study. Twelve-lead electrocardiography (ECG) was obtained from all patients during admission and 24 and 48 h after admission. We divided the patients into two groups according to the presence of fQRS appearance within 48 h absence of fQRS in any lead (fQRS-), and its presence in two or more contiguous leads (fQRS+). All patients were evaluated with transthoracic echocardiography at admission, and at follow-up 6 and 12 months later. RESULTS A total of 138 consecutive patients were included in the study. Seventy-three patients (52.9%) had fQRS in the ECG. EF recovery in the fQRS(+) group was significantly lower than that of the fQRS(-) group (39% vs. 43.9%, P less then 0.001). Multiple logistic regression analysis showed that the fQRS (odds ratio 4.147, 95% confidence interval 1.607-10.697, P = 0.003) were an independent predictor of poor EF recovery. CONCLUSION The presence of fQRS is an independent predictor for inadequate EF recovery in acute anterior STEMI patients undergoing thrombolytic treatment. Assessment of fQRS on surface ECG may be used in determining high-risk patients for poor EF recovery after acute anterior STEMI.OBJECTIVE Fibrinogen-to-albumin ratio (FAR) is an inexpensive and easily measurable novel inflammatory index that has been found to be associated with atherosclerosis. In this study, we aimed to investigate the association between the FAR and coronary artery disease (CAD) severity in patients with stable CAD. METHODS In total, 356 consecutive patients with CAD were classified into three groups, those with a low Synergy between percutaneous coronary intervention and the Taxus and Cardiac Surgery Study (SYNTAX) score (≤22), those with an intermediate SYNTAX score (23≥ SYNTAX score ≤32) and those with a high SYNTAX score (>32). RESULTS We determined that there were significant differences in the mean age (P  less then  0.001), male gender (P = 0.008), serum fibrinogen (P = 0.03), low-density lipoprotein cholesterol (P  less then  0.001) and FAR (P  less then  0.001) among the SYNTAX score groups. A strong positive correlation was detected between FAR and SYNTAX score (r = 0.899; P  less then  0.001), and the cutoff level of FAR for high SYNTAX score was 82 (sensitivity of 82%, specificity of 88.3% and an area under the curve of 0.826). CONCLUSION The novel inflammatory index, FAR, is significantly associated with the severity of CAD in patients with stable CAD.BACKGROUND Chronic total occlusion intervention remains challenging and detailed real-world data on the safety and efficacy of which are limited. This study sought to determine whether there are differences in the 1-year clinical outcomes between chronic total occlusion patients with acute coronary syndrome and stable angina following chronic total occlusion intervention. PATIENTS AND METHODS Data from the Korean chronic total occlusion registry were collected from May 2003 to September 2012, and a total of 3268 patients who underwent chronic total occlusion intervention were enrolled. Cardiovascular outcomes up to 12 months in the acute coronary syndrome group were compared with stable angina group. RESULTS The acute coronary syndrome group consisted of 1657 patients, and stable angina group consisted of 1264 patients. In the acute coronary syndrome group, patients with successful chronic total occlusion intervention had a lower incidence of total death and cardiac death compared to patients with failed intervention. However, there were no significant differences in cardiovascular events in the stable angina group. The successful chronic total occlusion intervention was a significant prognostic factor for lower total death (P = 0.006, hazard ratio = 0.46) and cardiac death (P = 0.003, hazard ratio = 0.36) within acute coronary syndrome group. On the other hand, successful chronic total occlusion intervention was not a prognostic factor for cardiovascular events within stable angina group. CONCLUSIONS Successful chronic total occlusion intervention in acute coronary syndrome patients was associated with a lower incidence of cardiovascular outcome compared to patients with failed chronic total occlusion intervention.BACKGROUND Cardiac rupture is a disastrous but uncommon complication of acute ST-elevation myocardial infarction (STEMI). JTC-801 solubility dmso The incidence, risk factors and in-hospital outcomes related to cardiac rupture in the current era are unknown. METHODS This study consecutively collected all acute STEMI patients admitted to a single tertiary center in China from January 2004 to December 2015. Characteristics of each cardiac rupture were collected and analyzed. RESULTS Among 4190 patients, 75 (1.8%) patients had cardiac rupture, including 33 at the ventricular septum and 42 at the left ventricle free wall (LVFW). Patients with cardiac rupture were more likely to be female, with more advanced age, lower rate of primary percutaneous coronary intervention (PPCI), and higher in-hospital mortality. Compared with survivors, the death cases were older, had a higher white blood cell count, higher rate of delayed admission (>12 h from symptom onset to door), earlier occurrence of cardiac rupture, higher percentage of LVFW rupture and lower rate of surgical repair. Logistic regression analysis showed that surgical repair served as the most valuable factor affecting survival. Moreover, elevated white blood cell count and advanced age might be related to an increased in-hospital death due to cardiac rupture. CONCLUSIONS In this contemporary cohort, female sex, advanced age and low rate of PPCI post-STEMI are associated with an increased risk of cardiac rupture. Advanced age and elevated white blood cell count might be related to an increased in-hospital mortality after cardiac rupture, whereas surgical repair served as the most valuable factor affecting survival.
