ABSTRACT
BACKGROUND AND OBJECTIVES: This meta-analysis was to investigate the efficacy and safety of new oral anticoagulant (NOAC) in atrial fibrillation (AF) patients with renal function insufficiency, and to explore whether renal decline occurs in AF patients with NOAC and its impact on outcomes. METHODS AND RESULTS: In AF patients with mild renal insufficiency, the NOAC was associated with significantly lower rates of stroke (odds ratio [OR], 0.78; 95% confidence interval [CI], 0.67-0.91; Pâ<â.05). Lower rates of bleeding were significantly observed in NOAC group (OR, 0.85; 95% CI, 0.75-0.97; Pâ<â.05). In AF patients with moderate renal impairment, similar results were revealed (OR for stroke or systemic embolism, 0.80; 95% CI, 0.67-0.95, Pâ<â.05; OR for major bleeding, 0.78; 95% CI, 0.59-1.03; Pâ=â.07). During the follow-up, pooled data revealed that NOAC showed a less renal toxicity, but the difference did not reach statistical significance (creatinine clearance decline: -0.12âmL/min [-0.84, 0.61âmL/min]). We have revealed that the NOACs were associated with significantly lower rates of stroke or systemic embolism (hazard ratio [HR], 0.66; 95% CI, 0.42-0.89; Pâ<â.05) and lower rates of bleeding (HR, 0.93; 95% CI, 0.70-1.16; Pâ=â.153) in AF patients with worsening renal function. CONCLUSIONS: NOAC may have the potentiality to be at least as effective as warfarin and may equal safety outcomes in AF patients with renal impairment. Renal decline during therapeutics may be less likely happened in NOAC than warfarin dose. NOAC may reveal good efficacy and safety outcomes in these scenarios. Further detailed research is needed to gain more clear profile on this new anticoagulant.

OBJECTIVE: To explore the associations between fasting serum lipids and high-sensitivity C-reactive protein (hsCRP). METHODS: Serum triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and hsCRP were measured in residents of Chengdu, China. Subjects with potential factors which might influence lipids and hsCRP were excluded, 580 subjects [mean age (62.3 ± 6.6) years; male: 58.7%] were finally recruited by random sampling methods. RESULTS: There was a weak positive relationship between TG and hsCRP (r = 0.108, P = 0.01) and a weak negative relationship between HDL-C and hsCRP (r = -0.197, P < 0.001), this was also true in the sub-group with BMI < 24 kg/m(2) (r = 0.236, -0.140 respectively, all P < 0.001). In subjects with BMI < 24 kg/m(2), the hsCRP concentration was significantly higher in subjects with higher TG or lower HDL-C (all P < 0.05). hsCRP increased in proportion with the degree of dyslipidemia. After adjusting for gender, age, TC, LDL-C, fasting blood glucose, systolic blood pressure, diastolic blood pressure, history of hypertension and diabetes, smoking and alcohol drinking, logistic regression analysis showed that the odds ratio for increased hsCRP was 1.970 in subjects with either increased TG or lower HDL-C (P = 0.105) and 9.098 in subjects with both higher TG or lower HDL-C levels (P = 0.031). However, the observed relationship between TG, HDL-C and hsCRP in subjects with BMI < 24 kg/m(2) could not be observed in subjects with subjects with BMI > 24 kg/m(2) despite significant more cardiovascular risk factors in these subjects. CONCLUSIONS: A weak positive correlation between TG and hsCRP as well as a weak negative correlation between HDL-C and hsCRP was evidenced in the whole cohort suggesting dyslipidemia might be related to enhanced inflammatory status. However, this relationship is not observed in subjects with BMI > 24 kg/m(2) despite existence of more cardiovascular risk factors in these subjects.

OBJECTIVE: To investigate the association between serum uric acid (UA) and early kidney damage and the prevalence of early kidney damage [89 >or= GFR >or= 60 ml * min(-1) * (1.73m(2))(-1)] in the middle-aged and elders with normal serum creatinine. METHODS: A survey of cardiovascular risk factors, including serum UA and estimated glomerular filtration rate (eGFR) [according to MDRD (modification of diet in renal disease) equation], was carried out in a local general population of Chengdu. A total of 1023 subjects with normal serum creatinine [mean age: (63 +/- 6) years; male: female = 52.7%: 47.3%] were recruited by random sampling method. The subjects were divided into 4 groups (A, B, C, D) according to the quartiles of serum UA levels (A: UA < 282 micromol/L, B: 282 micromol/L

OBJECTIVE: To analyse the clinical factors that contribute to the rise of the cardiac injury marker troponin after coronary intervention and the impact of the rise of troponin on the clinical outcomes. METHODS: Troponin I was measured after elective coronary intervention in 129 patients whose baseline levels of troponin were normal. The clinical outcomes of the patients were follow-up. RESULTS: The rise of troponin I was associated with side branch losses, flow impairments such as no flow or slow flow and diabetes. The incidence of myocardial infarction increased with the rise of troponin I. The angina onsets were more common and the length of stay were longer in the patients with the rise of troponin I than those without. CONCLUSION: The rise of troponin after coronary intervention is related to the complex coronary lesions and the complications of intervention procedures. To a certain extent, the level of troponin can predict the patients' outcomes.
