ABSTRACT
Objective To explore the effects of nicorandil on cardiac function and clinical outcomes in patients with acute myocardial infarction (AMI) undergoing percutaneous coronary intervention (PCI). Method Sixty-six patients with AMI were randomized into a control group and nicorandil group (n = 33 for each group). In the nicorandil group, nicorandil (4 mg as a bolus injection followed by constant infusion at 8 mg/hour for 24 hours) was administered immediately after admission. Reactive oxygen species (ROS) formation was assessed by measuring urinary excretion of 8-epi-prostaglandin F2α (PGF2α) and compared between the two groups; cardiac function and cardiac events were also compared. Results Urinary 8-epi-PGF2αexcretion was increased 2-fold at 60 to 90 minutes after PCI in the control group, whereas it was unchanged in the nicorandil group (P < 0.001). Left ventricular ejection fraction and cardiac index immediately after PCI and at 6 months were greater in the nicorandil group than in the control group(P < 0.05). Rates of total inhospital cardiac events and rehospitalization were lower in the nicorandil group than in the control group (P<0.05). Conclusions Nicorandil improves cardiac function and clinical outcomes in patients with AMI undergoing primary percutaneous coronary intervention. Suppression of ROS formation may be involved in the potential mechanism.
ABSTRACT
Objective: To analyze the relationship between the serum levels of low density lipoprotein cholesterol (LDL-C) and achilles tendon thickness (ATT). Methods: We studied 154 patients with high serum level of LDL-C (LDL-C≥3.37 mmol/L) from 2014-03 to 2015-03, the patients were at (18-75) years of age. According to《Guidelines on Prevention and Treatment of Blood Lipid Abnormality in Chinese Adults 2007》, the patients were divided into 2 groups:Borderline high LDL-C (3.3-4.12 mmol/L) group n=50 and High LDL-C (≥4.14 mmol/L) group, n=104;in addition, there was a Normal control group (LDL-C Results: ATT levels in High LDL-C group (9.42 ± 3.63) mm was higher than Borderline high group (8.24±1.73) mm and Normal control group (6.05±0.28)mm, all P Conclusion: Our preliminary research showed that the higher serum level of LDL-C associated with thicker ATT, they had positive correlation. This phenomenon should be further conifrmed by large sample and multi-center investigation.
