Acute myocardial infarction(AMI)is one of the leading causes of cardiac death.The percutane-ous coronary intervention(PCI)can improve the prognosis of AMI patients,but the overall prognosis of AMI patients is not optimistic.Hyperuricemia has become one of the risk factors for cardiovascular diseases.The role of hyperuricemia in the occurrence,development and prognosis of AMI has attracted increasing attention.This article reviews the research progress on the relationship between hyperuricemia and AMI.

Objective To investigate the effect of baseline Left-ventricular ejection fraction (LVEF) on the cardiac resynchronization therapy (CRT). Methods A retrospective analysis of patients with heart failure was performed. Fifty-four patients [aged (59.73 ± 11.61)years, 31 males, 23 females] who underwent CRT/CRTD were divided into 2 groups according to LVEF ( group A, LVEF≤ 35%; group B, LVEF > 35% ). NYHA class, LVEF,CRT respond rates and medical adverse event (MAE) due to worsening heart failure were detected at 3 and 12 months post-surgery. Results The score of NYHA class changing wasn′t different between these two group. Compared to group B, LVEF was markedly increased (5.08 ± 2.81)% vs (2.45 ± 1.80)%, P < 0.05;(5.38 ± 2.92)% vs (2.39 ± 3.53)%, P < 0.05)at 3 and 12 months post-surgery. Similarly, group A owned high CRT response rates(66.1% vs 33.9%, P < 0.05; 81.25% vs 47.83%, P < 0.05) at the both two time points. At 12 months post-surgery , LVED decreased and the MAE was similar in all groups. Conclusion Patients with EF≤ 35% have more increases in LVEF and own high CRT response rates post-CRT.

Objective To investigate influencing factors of perioperative myocardial injury in patients undergone percutaneous coronary intervention (PCI). Methods Ninty one patients with coronary heart disease (including stable angina and unstable angina) underwent PCI, the perioperative myocardial injury incidence were observed prospectively by monitoring the preoperative and postoperative high sensitivity troponin protein levels to investigate the influencing factors of perioperative myocardial injury by Logistic regression analysis. Results There were no statistically significance in perioperative myocardial injury incidence (62.5%vs 68.7%, P=0.618) and perioperative myocardial infarction incidence (29.2%vs 20.9%, P=0.411) between stable angina and unstable angina groups . These factors of perioperative myocardial injury in patients undergone PCI by Logistic regression analysis were analysed, and we found that the influencing factors were the application loading dose rosuvastatin before PCI, preoperative statin therapy more than one month, apolipoprotein A levels and total stent length. Conclusion Application loading dose of rosuvastatin before PCI, preoperative statin therapy more than one month, apolipoprotein A levels are related to perioperative myocardial injury reduction, whereas the total length of the stent is associated with an increased occurrence of perioperative myocardial injury.
