Objective: To investigate the acute effect of carotid artery stenting (CAS) on hemodynamics. Methods: We retrospectively analyzed 170 consecutive patients who received CAS in our hospital from 2014-09 to 2015-09. The acute effects of proximal internal CAS on blood pressure (BP) and heart rate (HR) were studied, the patients were followed-up for a month to observe the relationship between CAS and peri-operative adverse events occurrence. Results: ① Compared with pre-operative condition, the all day mean systolic blood pressure (SBP) from (126.6±15.1, 93-175) mmHg decreased to (117.7±13.7, 87-158) mmHg, P<0.01, all day mean DBP from (72.8±11.5, 49-100) mmHg decreased to (67.3±10.3, 48-90) mmHg, P<0.01, and all day HR from (66.3±6.8, 49-84) bpm decreased to (62.6±7.2, 49-88) bpm, P<0.01. ② The incidence of hemodynamic instability (HI) was 51.8% (88/170) and the occurrence rates of thypertension, hypotension and bradycardia were 3.5% (6/170), 39.4 % (67/170) and 22.4% (38/170) respectively. Multivariate regression analysis showed that HI was closely related to gender, history of hypertension, bilateral CAS and carotid bifurcation lesions. Upon HI onset, BP and HR could be restored to normal via intravenous infusion of vasoactive drugs and 6 (3.5%) patients having the medication time more than 24 hours. ③ Peri-operative adverse events happened in 8 (4.7%) patients including 4 transient ischemic attack, 2 minor stroke and 2 major stroke (1 patient died). The ratio of adverse events was 2.4% (2/82) in Non-HI group and 6.8% (6/88) in HI group, P=0.32. In HI group, the incidences of hypertension, hypotension, bradycardia and hypotension combining bradycardia were 16.7% (1/6), 6.8% (3/44), 0% (0/15) and 8.7% (2/23) respectively, compared with the overall patients' group, P=0.669, P=0.723, P=0.793 and P=0.658 respectively. Conclusion: HI incidence was relatively high in peri-operative period of CAS; gender, history of hypertension, bilateral CAS and carotid bifurcation lesions were the independent predictors for CAS occurrence. It is important to reasonably use vasoactive drugs in time for preventing and reducing HI related adverse events.

Chinese Circulation Journal 2017;32(10):984-988
Objective: To explore the effect of β-blocker in hypertension patients with different basic heart rate (HR). Methods: A total of 191 hypertension patients without using β-blocker were enrolled. Based on different basic HR, the patients were divided into 3 groups: Group A: HR (70-79) beats/min, n=58, Group B: HR (80-89) beats/min, n=90 and Group C: HR≥90 beats/min, n=43. All patients received metoprolol extended release at 47.5 mg/d for 2 weeks, for those didn't reach the target HR, 23.75 mg/d was added as 71.25 mg/d for 4 weeks, for those still didn't reach target HR, the dose was added to 95 mg/d, total length of medication was 8 weeks. Blood pressure (BP) and HR were measured every 2 weeks in all patients. Results: 62% patients had basic HR>80 beats/min, 36% had basic HR>85 beats/min and 20% had basic HR>90 beats/min. The average dose of metoprolol was (59.7±17.0) mg/d. HR decreased in 3 groups after medication, all P<0.05. The reducing level in Group C was (29.3±7.8) beats/min, in Group B was (18.7±4.9) beats/min and in Group A was (11.0±4.0) beats/min, P<0.05; upon HR elevating 10 beats/minute, metoprolol caused HR reducing may increase 7.9%. BP was similar among 3 groups before and after medication, P>0.05. The average HR decreasing levels in patients with metoprolol 47.5 mg/d, 71.25 mg/d and 95 mg/d were (17.6±8.1) beats/min, (19.5±8.7) beats/min and (22.5±9.2) beats/min respectively; upon dose elevated to 71.25 mg/d and 95 mg/d, metoprolol caused HR reducing may increase10.8% and 27.8%. 1 patient had sinus bradycardia and 1 had dizziness during medication, the symptoms improved by dose reducing or drug withdrawal.Conclusion: About 2/3 hypertension patients had basic HR>80 beats/min, metoprolol could cause more HR reducing in patients with the faster basic HR. Metoprolol (47.5-95) mg/d was safe and effective in hypertension patients.

Objective: To explore the relationship between plasma level of soluble urokinase plasminogen activator receptor (suPAR) and the severity of acute coronary syndrome (ACS) with its influence factors. Methods: A total of 321 consecutive patients with chest pain admitted in our hospital from 2015-03 to 2016-09 were studied. According to clinical presentation, laboratory test and coronary angiography (CAG), the patients were divided into 2 groups: ACS group, n=228 and Control group, the patients with normal coronary artery, n=93. Plasma levels of suPAR and high sensitive C reaction protein (hs-CRP) were measured by ELISA and compared between 2 groups. Results: The levels of plasma suPAR in ACS patients were significantly higher than those in the control group (OR= 0.104, 95% CI: 0.048-0.223, P<0.01). In ACS group, the plasma suPAR level gradually increased with the increase of Gensini score, The sensitivity and specificity of the levels of suPAR were determined by ROC curve. The values of ACS were predicted to be 1.8 μg / L, the sensitivity was 0.732 and the specificity was 0.710. Multiple linear regression analysis showed that smoking, Gensini score and uric acid were the main factors affecting plasma suPAR levels. Conclusion: Elevated plasma suPAR level has been related to the severity of coronary stenosis in ACS patients, such relationship is superior to hs-CRP; suPAR might be worked as a new biomarker for predicting coronary stenosis and risk stratification in ACS patients.

Objective: To explore the application status of trans-femoral route (TFR) and trans-radial route (TRR) percutaneous coronary intervention (PCI) via a single center large sample 2-year follow-up study and to evaluate their impact on long-term prognosis in relevant patients. Methods: A total of 10577 patients received PCI by TFR or TRR in our hospital during 2013 were analyzed. The patients were divided into two groups: TRR group, n=9745 (90.9%) and the TFR group, n=812 (7.6%). Clinical features were compared between 2 groups and their impacts on prognosis were studied. Results: Compared with TRR group, TFR group had more patients with elder age, more female, diabetes, more with the histories of myocardial infarction (MI), PCI or CABG, all P<0.001; more patients with left main disease or 3-vessel lesions, all P<0.001. Logistic regression analysis indicated that female, age, histories of MI, PCI or CABG and left main disease were the predictors for choosing TFR. With propensity score matching, TFR group had the higher in-hospital mortality than TRR group, P<0.05. 2-year follow-up Kaplan-Meier survival analysis showed that the end point events were similar between 2 groups. Cox multivariate analysis found that TFR was an independent risk factor of BARC ≥ 2 bleeding (HR=2.210, P=0.013), while not an independent risk factor for main cardiac end point events. Conclusion: ① Female, elder age, histories of MI, PCI or CABG and left main disease were the predictors for choosing TFR. ② The in-hospital mortality was higher in TFR PCI. ③ TFR was an independent risk factor of BARC≥2 bleeding, while it had no impact on long-term prognosis in PCI patients.
