Guanxin Danshen Dripping Pills Improve Quality of Life and Cardiovascular Prognoses of CHD Patients after PCI with Anxiety or Depression (GLAD Study): A Randomized Double-Blind Placebo-Controlled Study / 中国结合医学杂志

OBJECTIVE@#To assess the efficacy and safety of Guanxin Danshen Dripping Pills (GXDS) in the treatment of depression or anxiety in patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI).@*METHODS@#From September 2017 to June 2019, 200 CHD patients after PCI with depression and anxiety were included and randomly divided into GXDS (100 cases) and placebo control groups (100 cases) by block randomization and a random number table. Patients in the GXDS and control groups were given GXDS and placebo, respectively, 0.4 g each time, 3 times daily for 12 weeks. The primary outcomes were scores of Patient Health Questionnaire-9 (PHQ-9), Generalized Anxiety Scale (GAD-7) and the Seattle Angina Pectoris Scale (SAQ). The secondary outcomes included 12 Health Survey Summary Form (SF-12) scores and the first onset time and incidence of major adverse cardiovascular events (MACEs). Other indices including blood pressure, blood lipids, microcirculation and inflammatory-related indices, etc. were monitored at baseline, week 4, and week 12.@*RESULTS@#In the full analysis set (200 cases), after treatment, the PHQ-9 and GAD-7 scores in the GXDS group were considerably lower than those in the control group (P<0.05). Compared with the baseline, the total PHQ-9 scores of the experimental and control groups decreased by 3.97 and 1.18, respectively. The corrected mean difference between the two groups was -2.78 (95% CI: -3.47, -2.10; P<0.001). The total GAD-7 score in the GXDS group decreased by 3.48% compared with the baseline level, while that of the placebo group decreased by 1.13%. The corrected mean difference between the two groups was -2.35 (95% CI: -2.95, -1.76; P<0.001). The degree of improvement in SAQ score, SF-12 score, endothelin and high-sensitive C-reactive protein levels in the GXDS group were substantially superior than those in the placebo group, and the differences between the two groups were statistically significant (P<0.05). Similar results were obtained in the per protocol population analysis of 177 patients. Three cases of MACES were reported in this study (1 in the GXDS group and 2 in the placebo group), and no serious adverse events occurred.@*CONCLUSIONS@#GXDS can significantly alleviate depression and anxiety, relieve symptoms of angina, and improve quality of life in patients with CHD after PCI.

Self-reported quality of life in patients with coronary heart disease and analysis of the associated factors / 中华内科杂志

Objective: To investigate the quality of life and associated factors in patients with coronary heart disease (CHD) in China. Methods: A cross-sectional study of 25 provinces and cities in China was performed from June to September 2020. A questionnaire was used to collect the socio-demographic and clinical information of patients with CHD, while the European Five-dimensional Quality of Life Scale (EQ-5D) was used to assess the quality of life. Multiple linear regression model was performed to analyze the associated factors. Results: The median age of the 1 075 responders was 60 (52, 67) years, and 797 (74.1%) were men. The EQ-5D and EQ-VAS indices were 0.7 (0.5, 0.8) and 60.0 (40.0, 80.0). Among the five dimensions in the quality of life scale, the frequency of anxiety/depression was the highest (59.8%), while problems in self-care was the lowest (35.8%). In the multiple linear regression model, female, increasing age, obesity, comorbidity(ies), anxiety/depression, social media channels, and receiving the CABG therapy were associated with the lower EQ-5D index (all P<0.05). In addition, increasing age, obesity, comorbidity (ies), depression, anxiety and depression, social media channels, and receiving the CABG therapy were associated with lower EQ-VAS index (all P<0.05). Conclusion: Over half of the patients with CHD in China have a low quality of life, which is related to gender, age, obesity, treatment pathway, the presence or absence of comorbidity (ies), and psychological state. In addition to managing the adverse effects of traditional socio-demographic factors on the quality of life, clinical practices should pay attention to the psychological state of patients. Moreover, establishing a WeChat group for doctor-patient communication could improve the quality of life of CHD patients.

The long-term efficacy of left cardiac sympathetic denervation in long QT syndrome / 中华心血管病杂志

Objective: To investigate the long-term efficacy and safety of left cardiac sympathetic denervation(LCSD) for long QT syndrome(LQTS) patients with either recurrence on drug therapy intolerance/refusal. Methods: This study was a retrospective cohort study. The cases selected from 193 patients with LQTS who were enrolled in the Chinese Channelopathy Registry Study from November 1999 to November 2012. This study selected 28 LQTS patients with either recurrence on drug therapy intolerance/refusal and underwent LCSD surgery in the Peking University People's Hospital or Beijing Tongren Hospital. The patients were allocated into 3 groups: high-risk group(n=13, baseline QTc ≥550 ms or symptomatic in the first year of life or highly malignant genetics); intermediate-risk group(n=10, 500 ms≤baseline QTc<550 ms, symptomatic after the first year and without highly malignant genetics); low-risk group(n=5, baseline QTc<500 ms, symptomatic after the first year and without highly malignant genetics). LCSD was performed with the traditional supraclavicular approach or video assisted thoracoscopic surgery (VATS). Patients were regularly followed up until 20 years after the surgery. Data were collected before and 1 year after surgery and at the last follow-up. Patients' electrocardiograph(ECG), cardiac events and surgery-related complications were recorded. Kaplan-Meier survival analysis was used to determine the cardiac event-free survival based on different risk stratification and genotypes. Results: A total of 28 LQTS patients, aged 20.5 (15.0, 37.5) and underwent LCSD surgery, were enrolled in this study, including 23(82.1%) women. There were 11(39.3%) patients treated with traditional approach while 17(60.7%) with VATS-LCSD. There were 19(67.9%) patients had positive genetic test results, including 4 LQT1, 12 LQT2, 1 LQT1/LQT2 mixed type, and 2 Jervell-Lange-Nielsen (JLN) syndrome. The median follow-up period was 189.3(138.7, 204.9) months. The dropout rate was 10.7%(3/28) while 3 patients in the intermediate-risk group were lost to follow-up. Horner syndrome occurred in 1 patient (in the high-risk group). Sudden cardiac deaths were observed in 3 (12.0%) patients (all in the high-risk group), and 12 patients (48.0%) had syncope recurrences (2 in low-risk group, 3 in intermediate-risk group and 7 in high-risk group). A significant reduction in the mean yearly episodes of cardiac events was observed, from (3.5±3.3) before LCSD to(0.2±0.1) at one year after LCSD and (0.5±0.8) at last follow up(P<0.001). The mean QTc was shortened from (545.7±51.2)ms before the surgery to (489.0±40.1)ms at the last follow-up (P<0.001). Among the 20 patients with basic QTc ≥500 ms and completing the follow-up, the QTc intervals of 11(55.0%) patients were shortened to below 500 ms. The event free survival rates for any cardiac events after LCSD decreased sequentially in the low-, intermediate- and high-risk groups, and the difference was statistically significant (χ²=7.24, log-rank P=0.026). No difference was found in the event free survival rates among LQT1, LQT2 and undefined gene patients (χ²=5.20, log-rank P>0.05). Conclusions: LCSD surgery can reduce the incidence of cardiac events and shorten the QTc interval in patients with LQTS after the long-term follow-up. LCSD surgery is effective and safe for patients with LQTS ineffective or intolerant to drug therapy. However, high-risk patients are still at a high risk of sudden death after surgery and should be actively monitored and protected by combined therapies.

Cross sectional study of familial hypercholesterolemia in dyslipidemia patients receiving lipid-lowering therapy: DYSIS-China subgroup analysis / 中华心血管病杂志

Objectives: To analyze the incidence, blood lipid levels and cardiovascular disease of familial hypercholesterolemia (FH) in dyslipidemia patients receiving lipid-lowing therapy from the DYSIS-China. Methods: Dyslipidemia International Study-China (DYSIS-China) database was re-analyzed according to the criteria of "Chinese guidelines for prevention and treatment of dyslipidemia in adults-2016 version". DYSIS-China database included 25 317 dyslipidemia out-patients who received at least one lipid-lowering drug for at least three months. All the patients were divided into three groups: unlikely HF, possible FH and definite FH according to the Dutch Lipid Clinic Network diagnostic criteria. Age, gender, lipids levels, drug use and complications were compared among the three groups. Factors were compared between Possible FH group and definite FH group in terms of age stratification. Results: A total of 23 973 patients with dyslipidemia were included. The average age was (64.8±9.9) years, 11 757 patients were females (49.0%). The proportion of unlikely FH in the total population was 20 561 (85.7%), possible FH was 3294 (13.7%), and the definite FH was 118(0.5%). Patients in the definite FH group (58.3±8.5 years) was younger than in unlikely HF(65.3±9.8 years) and possible FH(61.8±9.9 years) group. LDL-C ((5.6±1.9) mmol/L) levels were significantly higher in definite FH group than in unlikely HF ((2.5±0.9) mmol/L) and possible FH ((4.3±1.0) mmol/L) group. TC ((7.4±1.8) mmol/L) levels were also significantly higher in definite FH group than in unlikely HF ((4.3±1.0) mmol/L) and possible FH ((6.0±1.0) mmol/L) group. Percent of female sex, sedentary lifestyle and systolic blood pressure value were significantly higher in definite FH group than in other two groups (all P<0.05). Statin use was similar among the 3 groups. Prevalence of ischemic cardiomyopathy (70(59.3%)) was significantly higher in the definite FH group than in unlikely FH group7519 (36.6%) and possible FH group1149 (34.9%). The rate of hypertension (82 (69.5%)) was also significantly higher in the definite FH group than in unlikely FH group (2 063 (62.6%) and in possible FH group (13 928 (67.7%)). The possible FH group had the highest proportion of patients aged 55-64 years (1 146 (34.8%)), and the prevalence of hypertension 358 (76.8%), diabetes 189 (40.6%), ischemic heart disease 186 (39.9%), cerebrovascular disease 149 (32.0%) and heart failure 28 (6.0%) was the highest in patients over 75 years old. The definite FH group had the highest proportion of patients aged 55-64 years (49 (41.52%)), and the prevalence of ischemic heart disease (70 (59.3%)) was the highest in patients aged 45-54 years old group, there was no significant difference in the prevalence of diabetes,hypertension,heart failure,peripheral artery disease and cerebrovascular disease among different age groups. Conclusion: The detection rate of FH in Chinese patients with dyslipidemia is not low, the blood lipid level is poorly controlled, and the risk of cardiovascular disease is high in Chinses FH patients.

Efficacy and safety comparison between pro-urokinase and reteplase in the treatment of patients with acute ST elevation myocardial infarction / 中华心血管病杂志

Objective: To compare the efficacy and safety of pro-urokinase and reteplase in the treatment of patients with acute ST elevation myocardial infarction (STEMI). Methods: STEMI patients, who received intravenous thrombolytic therapy in Henan STEMI registry between September 2016 and August 2018, were eligible for this study. A total of 5479 patients from 66 hospitals were screened and patients were divided into pro-urokinase group (n=638) and reteplase group (n=702) according to thrombolytic drugs. Data including patient demographics, risk factors, medical histories, patient information at admission, in-hospital treatment, time delays, and clinical events were collected. The clinical recanalization rate, in-hospital mortality, in-hospital death or treatment withdrawal, in-hospital main adverse cardiovascular and cerebrovascular events (MACCE, death or treatment withdrawal, congestive heart failure, reinfarction and ischemic stroke) and post-thrombolysis bleeding were compared between the two groups. Bleeding events were evaluated with Bleeding Academic Research Consortium (BARC) criteria. Results: The median age [61.8 (53.2, 69.0) vs. 62.6 (52.1, 69.8), P=0.833] or the proportion of women [23.0% (147/638) vs. 25.1% (176/702), P=0.385] were similar between the pro-urokinase and reteplase groups. Clinical recanalization rates were similar between the pro-urokinase and reteplase groups [82.1% (524/638) vs. 84.9% (596/702), P=0.172], and there was no difference in the median time from onset to thrombolysis [194.5 (135.0,290.0) min vs. 190 (126.0,292.0) min, P=0.431] and the median recanalization time [95 (67.5,120.0) min vs. 95 (71.0,119.0) min, P=0.561] between the two groups. There was no significant difference in in-hospital mortality [5.5% (35/638) vs. 5.1% (36/702), P =0.770], in-hospital all-cause mortality, treatment withdrawal [8.9% (57/638) vs.7.7% (54/702), P=0.410], and in-hospital MACCE [13.0% (83/638) vs. 10.4% (73/702), P=0.137] between pro-urokinase and reteplase groups. However, the incidence of post-thrombolysis bleeding was significantly higher in reteplase group than in pro-urokinase group [7.8% (55/702) vs. 3.8% (24/638), P=0.002]. Further analysis found that the incidence of oral bleeding and the BARC grades 1-2 bleeding were significantly higher in reteplase group than in pro-urokinase group, whereas the incidence of cerebral hemorrhage was similar between the two groups [0.6% (4/638) vs. 0.4% (3/702), P=0.715]. The comparison of efficacy and safety outcomes between the two groups after adjusting for baseline characteristics using general linear mixed models was consistent with those before the adjustment. There was no significant difference in in-hospital mortality, in-hospital death or treatment withdrawal, in-hospital MACCE after adjusting for baseline characteristics and post-thrombolysis bleeding between the two groups. Conclusions: Pro-urokinase and reteplase have similar clinical efficacy in the treatment of STEMI. In terms of safety, the incidence of cerebral hemorrhage is similar, while the incidence of BARC grades 1-2 bleeding and oral bleeding is higher in reteplase group than in pro-urokinase group, which has no impact on in-hospital outcomes.

Comparing the effects of depression, anxiety, and comorbidity on quality-of-life, adverse outcomes, and medical expenditure in Chinese patients with acute coronary syndrome / 中华医学杂志(英文版)

Background:@#Depression and anxiety have been correlated with elevated risks for quality-of-life (QOL), adverse outcomes, and medical expenditure in patients with acute coronary syndrome (ACS). However, the relevant data are lacking for Chinese ACS populations, especially regarding different effects of major depression, anxiety, and comorbidity. The objective of this study was to evaluate the dynamic changes of depression and/or anxiety over 12 months and examine the effects of depression, anxiety, and comorbidity on QOL, adverse outcomes, and medical expenditure in Chinese patients with ACS.@*Methods:@#For this prospective longitudinal study, a total of 647 patients with ACS were recruited from North China between January 2013 and June 2015. Among them, 531 patients (82.1%) completed 12-month follow-ups. Logistic regression model was utilized for analyzing the association of baseline major depression, anxiety, and comorbidity with 12-month all-cause mortality, cardiovascular events, QOL, and health expenditure.@*Results:@#During a follow-up period of 12 months, 7.3% experienced non-fatal myocardial infarction (MI) and 35.8% cardiac rehospitalization. Baseline comorbidity, rather than major depression/anxiety, strongly predicted poor 12-month QOL as measured by short-form health survey-12 (odds ratio [OR]: 1.77, 95% confidence interval [CI]: 1.22–2.52, P = 0.003). Regarding 12-month non-fatal MI and cardiac re-hospitalization, baseline anxiety (OR: 2.83, 95% CI: 1.33–5.89, P < 0.01; OR: 4.47, 95% CI: 1.50–13.00, P < 0.01), major depression (OR: 2.58, 95% CI: 1.02–6.15, P < 0.05; OR: 5.22, 95% CI: 1.42–17.57, P < 0.03), and comorbidity (OR: 6.33, 95% CI: 2.96–13.79, P < 0.0001, OR: 14.08, 95% CI: 4.99–41.66, P < 0.0001) were all independent predictors, and comorbidity had the highest predictive value. Number of re-hospitalization stay, admission frequency within 12 months and medical expenditure within 2 months were the highest in patients with ACS with comorbidity.@*Conclusions:@#Major depression and anxiety may predict 12-month non-fatal MI and cardiac re-hospitalization. However, comorbidity has the highest predictive value with greater medical expenditure and worse QOL in Chinese patients with ACS. And depression with comorbid anxiety may be a new target of mood status in patients with ACS.

Effect of Long-Term Systolic Blood Pressure Trajectory on Kidney Damage in the Diabetic Population: A Prospective Study in a Community-Based Chinese Cohort / 中华医学杂志(英文版)

<p><b>Background</b>Previous studies have shown that hypertension is an important factor contributing to the occurrence and progression of diabetic kidney damage. However, the relationship between the patterns of blood pressure (BP) trajectory and kidney damage in the diabetic population remains unclear. This prospective study investigated the effect of long-term systolic BP (SBP) trajectory on kidney damage in the diabetic population based on an 8-year follow-up community-based cohort.</p><p><b>Methods</b>This study included 4556 diabetic participants among 101,510 participants. BP, estimated glomerular filtration rate (eGFR), and urinary protein were measured every 2 years from 2006 to 2014. SBP trajectory was identified by the censored normal modeling. Five discrete SBP trajectories were identified according to SBP range and the changing pattern over time. Kidney damage was evaluated through eGFR and urinary protein value. A multivariate logistic regression model was used to analyze the influence of different SBP trajectory groups on kidney damage.</p><p><b>Results</b>We identified five discrete SBP trajectories: low-stable group (n = 864), moderate-stable group (n = 1980), moderate increasing group (n = 609), elevated decreasing group, (n = 679), and elevated stable group (n = 424). The detection rate of kidney damage in the low-stable group (SBP: 118-124 mmHg) was the lowest among the five groups. The detection rate of each kidney damage index was higher in the elevated stable group (SBP: 159-172 mmHg) compared with the low-stable group. For details, the gap was 4.14 (11.6% vs. 2.8%) in eGFR <60 ml·min·1.73 m and 3.66 (17.2% vs. 4.7%), 3.38 (25.0% vs. 7.4%), and 1.8 (10.6% vs. 5.9%) times in positive urinary protein, eGFR <60 ml·min·1.73 m and/or positive urinary protein, and eGFR decline ≥30%, respectively (P < 0.01).</p><p><b>Conclusion</b>An elevated stable SBP trajectory is an independent risk factor for kidney damage in the diabetic population.</p>

<p><b>OBJECTIVE</b>To evaluate the effectiveness and safety of L-amlodipine besylate for blood pressure control in patients with mild to moderate essential hypertension.</p><p><b>METHOD</b>A total of 1051 mild to moderate essential hypertensives were recruited from 22 centers and randomized into three groups and were given low-dose L-amlodipine besylate (2.5 mg/d), high-dose L-amlodipine besylate (5.0 mg/d), and amlodipine maleate (5.0 mg/d) on the principle of open-label and parallel control. The study drugs were administered for 8 weeks.</p><p><b>RESULTS</b>After 8 weeks treatments, the response rate of the three groups were 72.4%, 85.6%, and 76.2%, respectively. The rate difference between high-dose L-amlodipine besylate group and the other two groups were statistically significant (P < 0.01), while the rate difference between low-dose L-amlodipine besylate group and amlodipine maleate group was similar (P = 0.28). The event rates of the three groups were similar (4.3%, 4.6%, and 5.1%, respectively, P = 0.84).</p><p><b>CONCLUSION</b>High-dose L-amlodipine besylate is superior to the other 2 groups on blood pressure control. The efficacy profiles of amlodipine maleate and low-dose L-amlodipine besylate are equivalent. Safety profiles of these three groups are comparable.</p>

Control rate of increased low-density lipoprotein cholesterol levels in cardiology outpatients with coronary heart disease in Beijing / 中华心血管病杂志

<p><b>OBJECTIVE</b>To investigate the low-density lipoprotein cholesterol (LDL-C) levels in outpatients with coronary heart disease (CHD) visiting cardiology outpatient clinics of 8 hospitals in Beijing.</p><p><b>METHODS</b>A total of 903 outpatients with CHD were enrolled from 4 three-tier hospitals and 4 two-tier hospitals in Beijing. All patients were asked to finish the questionnaire including demographic data, CHD history, the knowledge on cholesterol, and the use of statins. Blood lipid was examined and the LDL-C control rate and related factors were then analyzed.</p><p><b>RESULTS</b>Questionnaire was obtained from 876 patients [619 male: 70.7%, mean age: (64.9 ± 10.7) years old] and blood lipid data were available in 709 patients. The general LDL-C control rate was 36.9% (262/709) and was 13.5% (27/173) in very high risk CHD patients, and lower in patients treated in two-tier hospitals than patients treated in three-tier hospitals[31.3% (121/386) vs. 43.7% (141/323), P < 0.01], in female patients than in male patients [27.1% (60/261) vs. 41.3% (201/496), P < 0.01] and in diabetic patients than in non-diabetic patients [13.5% (27/200) vs. 44.7% (197/441), P < 0.01]. The LDL-C control rate was lower in patients less than 60 years old and patients over 80 years old than that in 60-70 years old patients and 70 - 80 years old patients (P < 0.05). LDL-C control rate was not affected by the history of hypertension, percutaneous coronary intervention or coronary artery bypass grafting, smoking, lipid examination frequency, knowledge on goal level of LDL-C, diet control and regularly physical exercising (all P > 0.05). There were 18.2% (129/709) patients not taking statins or not aware if they were taking statin or not. The main reason for not taking statin [47.9% (23/48)] was statin was no prescribed by doctors, followed by withdrawal by patients due to various reasons [27.1% (13/48)].</p><p><b>CONCLUSIONS</b>LDL-C control rate was low in patients with CHD visiting cardiology outpatient clinics in Beijing. The CHD patients and cardiologists should be encouraged to achieve better LDL-C control by following lipid lowering guidelines and it is also important to improve the drug compliance among CHD patients.</p>

Population characteristics and impact on heart rate variability, heart rate and blood pressure of passive smoking / 中华心血管病杂志

<p><b>OBJECTIVE</b>To investigate the basic characteristics of passive smoking population, and the impact of passive smoking on heart rate variability, heart rate and blood pressure.</p><p><b>METHODS</b>Eighty-six passive smokers [mean age: (52.4 ± 7.6) years] were recruited from patients and their relatives who visited cardiovascular outpatient department and excluded structural heart disease between June 2010 and June 2012, 80 normal subjects who were not exposed to smoking served as controls. Questionnaire survey, 24 hours ambulatory electrocardiogram examination and blood pressure measurement were performed in all recruited subjects.</p><p><b>RESULTS</b>(1) Non-marriage rate [18.60% (16/86) vs. 3.75% (3/80), P < 0.01] was significantly higher while education level were significantly lower in passive smoking group than in control group. Passive smokers were more likely service industry workers [29.07% (25/86) vs. 15.00% (12/80), P < 0.05] and had longer daily working time [(7.56 ± 1.24) h vs. (6.02 ± 0.96) h, P < 0.01], and were less likely to be professional technology industry employers [20.93% (18/86) vs. 36.25% (29/80), P < 0.05] and managers [13.95% (12/86) vs. 38.75% (31/80), P < 0.01] compared to controls. The main place of passive smoking was workplace (67.44%, 58/86), entertainment venues (63.95%,55/86), restaurants (48.84%, 42/86). (2) Standard of the normal sinus RR intervals (SDNN), the normal consecutive sinus RR interval difference between the root-mean-square (rMSSD) and adjacent the difference between the RR interval>50 ms the number of share the percentage (PNN50) were significantly lower in passive smoking group than in the control group (all P < 0.05). Every 5 min average of the standard deviation of sinus RR cycle (SDNN index) and 24 h every 5 min sinus RR interval mean standard deviation (SDANN) were similar between the 2 groups (all P > 0.05). Ultra-low-frequency power (VLF), low frequency power (LF), high frequency power (HF) and LF/HF were significantly lower in passive smoking group than in the control group (all P < 0.01). (3) Heart rate and diastolic blood pressure were significantly higher in passive smoking group than in control group (all P < 0.05) while systolic blood pressure was similar between the 2 groups (P > 0.05).</p><p><b>CONCLUSIONS</b>Marriage status, education level, profession and daily working time are independent determinants for passive smoking. Passive smoking mainly occurred in the workplace, entertainment venues and restaurants.

Efficacy and safety of tirofiban use after successful percutaneous coronary intervention for patients with moderate to high risk non-ST segment elevation acute coronary syndromes / 中华心血管病杂志

<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of tirofiban use immediately after successful percutaneous coronary intervention (PCI) in patients with moderate to high risk non-ST segment elevation acute coronary syndromes (NSTE-ACS).</p><p><b>METHODS</b>NSTE-ACS patients undergoing successful PCI (n = 246) were randomized by the envelope method to tirofiban group (n = 122, 10 µg/kg bolus within 3 min followed by 0.10-0.15 µg×kg(-1)×min(-1) for 36 h i.v.) or control group (n = 124, saline i.v. for 36 h). The primary efficacy composite end point was death, myocardial infarction, target vascular revascularization or ischemic stroke at 30 days. The second end point was the occurrence of composite end point at 7 days or 6 months. Key safety end points were bleeding and thrombocytopenia 3 days after PCI.</p><p><b>RESULTS</b>Baseline characteristics were well-balanced between the two groups (P > 0.05). The primary end point occurred in 0.9% (1/117) patients in the tirofiban group and 3.3% (4/123) patients of those in the control group (P = 0.40). There was no significant difference in the composite end point at 7 days [0.8% (1/122) vs. 3.2% (4/124), P = 0.38] between the groups, however, there was a trend towards lower composite efficacy end points at 6 months in tirofiban group compared to control group [0.9% (1/117) vs. 5.9% (7/118), P = 0.07]. The probability of survival free of composite end point was significantly higher in the tirofiban group than that in the control group (99.2% vs. 94.2%, log-rank test, P = 0.03). There was no GUSTO severe or moderate bleeding or severe thrombocytopenia within 3 days post-PCI. There was no significant difference in mild bleeding [13.1% (16/122) vs. 7.3% (9/124), P = 0.13] or mild thrombocytopenia [0.8% (1/122) vs. 0.8% (1/124), P = 1.00] between the groups.</p><p><b>CONCLUSION</b>Tirofiban use after successful PCI can improve 6-month event-free survival without increasing the risk of bleeding for patients with moderate to high risk NSTE-ACS.</p>

Types and risk factors of arrhythmia on young patients with acute coronary syndrome in Henan province / 中华心血管病杂志

<p><b>OBJECTIVE</b>The types and risk factors of arrhythmia were analyzed on acute coronary syndrome (ACS) patients under the age of 44 years who were hospitalized in Henan province between September 2009 to June 2012.</p><p><b>METHODS</b>Medical records of eligible patients were obtained from the information system of the First Affiliated Hospital of Zhengzhou University teleconsultation information center. Middle aged and elderly ACS patients who were hospitalized at the same period served as controls. Data on arrhythmia types, blood pressure, thyroid disease, respiratory sleep apnea syndrome, smoking history, history of alcohol consumption, eating habits, family history of early-onset arrhythmia, laboratory tests were analyzed.</p><p><b>RESULTS</b>(1) Arrhythmia was detected in 110 out of young ACS patients (55%), which was significantly lower than that in the elderly ACS patients (71.05%, P < 0.01). (2) The top three arrhythmias in young ACS patients were: sinus tachycardia (30.50%), the premature ventricular contractions (19.00%), atrial flutter/atrial fibrillation (16.50%). Incidence of sinus tachycardia, atrial flutter/atrial fibrillation were significantly higher while incidence of ventricular tachycardia, ventricular fibrillation, paroxysmal supraventricular tachycardia were significantly lower in young ACS patients than in middle-aged ACS patients (all P < 0.05). The incidence of sinus tachycardia was higher while incidence of ventricular premature accelerated ventricular spontaneous cardiac rhythm, ventricular tachycardia, ventricular fibrillation, non-paroxysmal supraventricular tachycardia, atrial flutter/atrial fibrillation, paroxysmal supraventricular tachycardia, sinus bradycardia, nodal escape, atrioventricular block were significantly lower in young ACS patients than in elderly ACS patients (all P < 0.05). (3) Body mass index, incidence of smoking, coronary three-vessel disease, drinking, eating salty foods, thyroid dysfunction, sleep apnea were significantly higher in youth ACS patients with arrhythmia than in young ACS patients without arrhythmia (all P < 0. 05). (4) Logistic regression analysis found that number of diseased coronary vessels (OR = 24.293), smoking (OR = 1.112) and alcohol consumption (OR = 1.039) were independent risk factor for developing arrhythmia in young ACS patients from Henan province.</p><p><b>CONCLUSIONS</b>The main types of arrhythmia are sinus tachycardia, premature ventricular contractions, atrial flutter/atrial fibrillation and the major risk factors related to the arrhythmia are number of diseased coronary vessels, smoking and alcohol consumption in young ACS patients from Henan province.</p>

Impact of therapy options on in-hospital and three-year outcome of patients with ST-elevation myocardial infarction in Beijing / 中华心血管病杂志

<p><b>OBJECTIVES</b>To evaluate the clinical characteristics, in-hospital and three-year outcome in ST-elevation myocardial Infraction (STEMI) patients receiving conservative treatment (CT), thrombolytic treatment (TT) and primary percutaneous coronary intervention (PCI) in Beijing.</p><p><b>METHODS</b>This 12-month prospective, multicenter registry study was conducted in 19 hospitals with 808 patients with STEMI in Beijing between Jan. 2006 and Dec. 2006, 518 (64%) received PCI, 106 (16.1%) received TT and 184 (22.8%) received CT therapy. Patients were followed up for 3 years.</p><p><b>RESULTS</b>At baseline, the age of patients in CT group [(64.5 ± 13.5) years] was significantly higher than those in TT group p(57.9 ± 11.0) years] and in PCI group [ (60.4 ± 12.3) years, all P<0.01]; and the median time from symptom onset to hospital in CT group (207 min) was significantly longer than those in TT group (130 min) and PCI group (130 min, all P<0.01). Emergency Medical Service (EMS) use was significantly higher in PCI group (184/518, 35.5%) than in CT group (46/184, 27.3%) and TT group (29/107, 25.0%, all P<0.05). Health insurance holder was the highest in PCI group (P<0.01). PCI was performed less frequently than thrombolytic therapy [66.6% (345/518) vs. 80.2% (85/106)m P=0.02] during off-hours and more frequently performed in tertiary hospitals than in secondary hospitals[66.8%(437/651) vs. 52.6% (81/154, P<0.01)]. The in-hospital mortality and the cardiovascular mortality at 3 year after hospital discharge was significantly higher in CT group [9.2% (17/185) and 9.4% (15/159)] than in PCI group [3.5% (18/518), 4.5% (20/446)] and TT group [6.6% (7/106), 2.3% (2/86), all P<0.01]. Patients in PCI group had the highest adherence level of aspirin, β-blocker, angiotensin-converting enzyme inhibitors/angiotensin-receptor blockers or statins at 3-years follow-up (all P<0.05). Multivariable Cox proportional hazards regression analysis showed that only PCI was associated with lower risk of cardiovascular death (HR-0.40, 95% CI:0.21-0.73, P<0.01).</p><p><b>CONCLUSIONS</b>Social and clinical setting may affect the physician's decision to provide reperfusion therapy in Beijing for STEMI patients. Better adherence of secondary preventive drugs and lower cardiovascular death are observed in STEMI patients receiving PCI during the 3-year follow-up</p>

Effect of the smoking cessation services in the out-patient department for patients with coronary heart disease / 中华心血管病杂志

<p><b>OBJECTIVE</b>To evaluate the effects and clinical prognosis of out-patient department-based smoking cessation services for coronary heart disease (CHD) patients.</p><p><b>METHODS</b>A total of 140 smoking patients diagnosed with coronary heart disease in our cardiovascular department were randomly divided into the intensive smoking cessation clinic follow-up group (intervention group, patients were informed on the importance and methods to quit smoking at the first visit and reminded for that at months interval for 6 months, n = 70) and the conventional treatment group (control group, n = 70). After 6 months, the smoking status, cardiovascular event rates, drug usage, out-patient medical costs and quality of life were compared between the two groups.</p><p><b>RESULTS</b>Age, gender, concomitant diseases, drug usage were similar between the two groups at baseline (all P > 0.05). After 6 months, smoking quit rate [34.2% (24/70) vs. 5.7% (4/70), P < 0.01], drug use rates: lipid-lowering drugs [95.3% (67/70) vs. 80.4% (56/70)], β blockers [82.4% (57/70) vs. 41.3% (28/70)], and ACEI/ARB [61.4% (43/70) vs. 34.4% (24/70)] were significantly higher in the intervention group than in the control group, while total cardiovascular event rates [21.4% (15/70) vs. 47.1% (33/70), P < 0.01] and out-patient medical costs (3789.3 RMB vs. 4984.2 RMB, P < 0.01) were significantly lower in the intervention group than in the control group. The quality of life scores derived from MYO health survey questionnaire was significantly higher in the intervention group than in the control group (P < 0.01). The top three reasons responsible for continuous smoking for all patients failed to quit smoking were: (1) others smoked more than me and still alive and healthy [90.3% (56/62)]; (2) smoking helped me to keep relaxed and reduce trouble in daily work and life [70.9% (44/62)]; (3) smoking was essential while chatting and drinking with friends [66.1% (41/62)]. The overall satisfactory rate to this smoking cessation program was 42.8% and the satisfactory rate was up to 50.0% by patients.</p><p><b>CONCLUSIONS</b>Intensive outpatient smoking cessation follow-up program can significantly improve the smoking cessation rates, the guideline drug use rate and the quality of life while reduce medical costs for coronary heart disease patients.</p>

Status and trend of cardio-cerebral-vascular diseases mortality in China: data from national disease surveillance system between 2004 and 2008 / 中华心血管病杂志

<p><b>OBJECTIVE</b>To report the status and trend of cardio-cerebral-vascular disease (CCVD) mortality in China between 2004 and 2008.</p><p><b>METHODS</b>The mortality data from population-based survey of National Disease Surveillance System in 2004 and 2008 were analyzed. This surveillance system is consisted of 161 disease surveillance points (DSPs) located in 31 provinces of China including 64 urban and 97 rural DSPs. The total population of surveillance is over 73 millions and accounted for around 6% of the whole population of China. CCVD included ischemic heart diseases (ICD-10: I05-I09, I11, I20-I27, I30-I52) and cerebral-vascular disease (ICD-10: I60-I69). The status and trend of cardiovascular disease (CVD), cerebral-vascular disease (CD), ischemic heart disease (IHD) and acute myocardial infarction (AMI) mortalities from 2004 to 2008 were analyzed by age, gender, and urban/rural regions.</p><p><b>RESULTS</b>The mortality of CCVD was higher in 2008 (229/100 000) than in 2004 (223.5/100 000), which was decreased in urban region (-11.7/100 000) while increased in rural region (+16.0/100 000). The mortality of CD decreased from 134.8/100 000 (2004) to 128.3/100 000 (2008). Mortality of IHD and AMI increased from 66.1/100 000 and 40.4/100 000 (2004) to 71/100 000 and 45.7/100 000 (2008), which remained stable in urban region (+0.98/100 000 and -1.96/100 000) while significantly increased in rural region (+6.7/100 000 and +9.2/100 000). The mortality rates for CVD, CD and AMI were higher in rural population than that in urban population. The age-standardized mortality rates of CVD, CD and IHD were lower in 2008 than in 2004. The mortality rates of CD and IHD decreased in 40-, 60-, and over 80 age groups (except for IHD) in 2008 than in 2004. However, IHD mortality was significantly higher in age of 80 and over group from 2004 to 2008. There were a net 5.5/100 000 increase, 6.4/100 000 decrease and 4.9/100 000 increase for CCVD, CD and IHD between 2004 and 2008. The mortality rate rise in CCVD was mainly due to the increased mortality of IHD and CD in rural population. The CCVD mortality increased with age and was significantly higher in male than in female population.</p><p><b>CONCLUSIONS</b>Despite decreased mortality in CD, CCVD mortality increased from 2004 to 2008, mainly due to the increased mortality of IHD and AMI in rural population. Enhanced CCVD primary and secondary prevention, particular for stressing on primary prevention, is necessary in China, especially in rural areas. Meanwhile, they will give the greatest contributions for a raise of the healthy life expectancy in China.</p>
