ABSTRACT

OBJECTIVE: To investigate the safety and efficacy of intravenous thrombolysis with recombinant tissue plasminogen activator (rt-PA) in patients with acute ischemic stroke (AIS) and cerebral microbleeds (CMBs) and analyze the risk factors for hemorrhagic transformation (HT). PATIENTS AND METHODS: The clinical data of 220 patients with CMB within the first 4.5 h after the onset of acute ischemic stroke treated in our hospital from September 2018 to December 2019 were retrospectively analyzed. Then, these patients were evenly assigned into two groups based on whether the intravenous thrombolysis with rt-PA was adopted or not. Next, the neurological deficit was scored using the National Institute of Health stroke scale (NIHSS) before and after treatment, the modified Rankin scale (mRs) score of patients was recorded at 90 d after treatment, and the incidence rate and death rate of intracranial hemorrhage (ICH) after treatment were recorded and evaluated. Additionally, the univariate and logistic regression analyses were employed for the risk factors for HT in patients after thrombolysis. RESULTS: The NIHSS score declined to (7.08±3.75) points and (7.83±4.22) points at 24 h after treatment and (3.67±3.63) points and (4.92±3.87) points at 7 d after treatment, respectively, in Thrombolysis group and Control group, which were significantly lower than those before treatment (p<0.05). The NIHSS score displayed no statistically significant difference between the two groups at 24 h after treatment (p=0.165), whereas it was markedly lower in Thrombolysis group than that in Control group at 7 d after treatment (p=0.015). At 90 d after treatment, there were 98 (89.1%) and 79 (71.8%) cases of good prognosis in Thrombolysis group and Control group, respectively, and the difference was statistically significant between the two groups (p=0.002). Besides, the number of patients with SICH and aSICH was 3 and 2 (2.7% vs. 1.8%, p=0.651) and 9 and 4 (8.2% vs. 3.6%, p=0.152) in Thrombolysis group and Control group, respectively, and the number of deaths was 7 and 5 (6.4% vs. 4.5%, p=0.553) in the two groups, showing no statistically significant difference. The results of univariate and multivariate analyses revealed that the time from stroke onset to thrombolysis, baseline NIHSS score, and history of atrial fibrillation were independent risk factors affecting the HT of patients undergoing intravenous thrombolysis [odds ratio (OR) =1.330, 95% confidence interval (95% CI) =1.079-1.851, p=0.019; OR=1.592, 95% CI=1.025-2.767, p=0.010; OR=2.428, 95% CI=1.814-3.643, p=0.016]. CONCLUSIONS: Compared with those undergoing no intravenous thrombolysis with rt-PA, patients with acute ischemic stroke and CMB who received intravenous thrombolysis with rt-PA exhibit significantly improved short-term neurological function recovery and long-term prognosis, but the incidence and mortality rates of ICH have no statistically significant differences. Moreover, the time from stroke onset to thrombolysis, baseline NIHSS score, and history of atrial fibrillation are independent risk factors affecting the HT of patients treated with intravenous thrombolysis.

ABSTRACT

Objective: To evaluate the clinical outcomes of on-pump total arterial revascularization with bilateral radial artery (BRA) and left internal mammary artery (LIMA) as conduits in coronary artery bypass grafting (CABG) patients with left ventricular dysfunction (LVD). Methods: All the perioperative medical records and follow-up results of coronary artery disease patients with left ventricular ejection fraction (LVEF) ≤ 40% undergoing CABG from 24 heart centers of 15 provinces and autonomous regions in China between July 2015 and December 2019 were retrospectively analyzed. Results: A total of 87 consecutive patients (55 males and 32 females) underwent on-pump CABG with BRA and LIMA, with a mean age of (57.5±9.1) years old. There were 22 patients complicated with primary hypertension, 12 with diabetes mellitus, 8 with peripheral vascular disease, 7 with chronic obstructive lung disease, 12 with mild renal injury and 3 with partial aortic calcification. There were 43 cases with in-stent stenosis, and 21 had left main disease. The mean LVEF and left ventricular end-diastolic diameter (LVEDD) was (35.5±7.3)% and (65.5±2.6) mm, respectively. The mean graft number, aortic cross-clamp time and cardiopulmonary bypass duration was 3.2±0.9, (90.5±22.7) min and (113.4±19.2) min, respectively. There were 32 mitral and 9 aortic valve replacements, and 5 tricuspid annuloplasties. Prophylactic intra-aortic balloon pumps were implanted in 27 patients. There were 2 operative deaths from acute heart failure. After surgery, there were 15 cases of atrial fibrillation, 1 case of acute kidney injury, 1 case of acute myocardial infarction, and 1 cases of stroke. All the patients fulfilled the follow-up, with a mean time of (39.5±7.7) months. At 3 months after surgery, LVEDD was decreased and LVEF was improved significantly compared with pre-operative indicators [(53.0±1.5) mm vs (65.5±2.6) mm, t=9.51 P=0.02; (45.2±3.3)% vs (35.5±7.3)%, t=13.79, P=0.001]. No major cardiac events were reported during the follow-up. At (30.5±7.4) months after surgery, 62.4% of patients (53/85) underwent coronary CT angiography examination, and the results indicated that the graft patency was 98.8%, with only one case of RA occlusion occurred. Conclusion: In selected patients of LVD, on-pump total arterial revascularization with BRA and LIMA conduits was proved to be safe and effective.

ABSTRACT

The current study was to determine the predictors of survival in 491 Chinese patients with lupus nephritis (LN). All patients were evaluated and consecutively followed up from 2003 to 2010. The female: male ratio was 9.5:1, with a median age of 31.1 ± 12 years. Forty-nine (10.0%) patients were lost to follow-up and 47 (10.3%) patients died. The overall cumulative probability of survival at 5, 10, 15 and 20 years by Kaplan-Meier analysis was 88%, 77%, 53% and 45%, respectively. The log-rank test showed that the probability of survival was significantly decreased in the late-onset patients (≥50 years) (P = 0.036), patients with hypoproteinaemia (≤35 g/l) (P = 0.014), patients with increased creatinine (≥1.5 mg/dl) (P = 0.002) and patients with massive proteinuria (≥3.5 g/24 h) (P = 0.009). However, the probability of survival was significantly higher in patients treated with hydroxychloroquine (HCQ) (P = 0.003) than those not treated with it. Based on a multivariate model, increased creatinine (hazard ratio (HR) = 2.041; P = 0.017) and proteinuria ≥3.5 g/24hours (HR=1.716; P = 0.016) were independent risk factors. Glucocorticoid (HR = 0.457; P = 0.01) and HCQ (HR=0.197; P = 0.026) were independent protective factors. Our findings suggest that renal dysfunction and massive proteinuria are independent risk factors for mortality. HCQ could improve the survival of patients with LN.
