Value of Lp (a) in risk assessment of patients with non ST-elevation acute coronary syndrome / 中华老年心脑血管病杂志

Objective To study the value of Lp (a) in risk assessment of patients with NSTE-ACS.Methods Eighty NSTE-ACS patients were divided into elderly NSTE-ACS group (n=58) and non elderly NSTE-ACS group (n=22) with 22 elderly patients with their coronary artery stenosis ＜ 50％ served as a control group.The relationship of serum Lp (a) level with Gensini score and GRACE risk score was analyzed.Results The incidence of hypertension and DM was significantly higher,the smoking history was significantly longer,the serum LDL-C and FBG level,Gensini score and GRACE risk score were significantly higher in elderly NSTE-ACS group than in control group (P＜0.05).The age was significantly older and the GRACE risk score was significantly higher in elderly NSTE-ACS group than in non elderly NSTE-ACS group (P＜0.05).The Gensini score and GRACE risk score were positively related wtih the serum Lp (a) level (r=0.494,P＜ 0.01;r=0.432,P＜0.01).Serum Lp (a) level was an independent risk factor for NSTE-ACS (P＜0.01).Conclusion Serum Lp (a) level is closely related with the severity and outcome of NSTE-ACS,indicating that serum Lp (a) level can be used as a predictor of risk assessment in NSTE-ACS patients.

Correlations of age and gender with the effects of cardiac resynchronization therapy in chronic heart failure patients / 医学研究生学报

Objective Various factors may affect the effects of cardiac resynchronization therapy or cardiac resynchronization and implantable cardioverter-defibrilator ( CRT/CRTD) in chronic heart failure patients ( CHF) .The aim of our study was to explore the correlation of age and gender with the effects of CRT/CRTD in chronic heart failure patients. Methods This study included 136 CHF patients, 92 males and 44 females, treated by CRT/CRTD from January 2005 to March 2015.We divided the patients into three age groups:≥70 yr (n=29), 50-70 yr (n=77), and 0.05).However, the CRT responding rate was remarkably higher in the female than in the male patients (66%vs 47%, P=0.027).Cox multivariate and Kaplan-Meier analyses revealed no significant differences in all-cause mortality between different genders or age groups.Multivariate logistic regression analysis showed that the left ventricular diastolic diameter and base QRS duration were independent factors of the CRT response. Conclusion Age does not affect the CRT response in chronic heart failure patients, while female patients have a higher CRT respon-ding rate than male patients.
