Objective To evaluate the therapeutic strategy and effects of surgical treatment for patients with closed trauma of heart valves. Method A total of 32 patients, 28 male and 4 female, aged from 21 to 48 years old with closed trauma of heart valves treated with surgical intervention from June 1987 to November 2008 were retrospectively studied. The duration from trauma to surgical treatment ranged from 18 days to 4 years. Results There was no peri-operative mortality within 30 days. Clinical follow-up for one month to 22 years showed cerebral hemorrhage in only one patient 27 months later and sudden death in one patient probably due to choke of the valve.Conclusions The mortality of patients with closed trauma of heart valves may be decreased by timely and correct diagnosis and treatment, and the outcomes may be improved.

Objective To evaluate the quality of life status in patients aged 70 years and over following off-pump coronary artery bypass (OPCAB) grafting. Methods Seventy-eight patients with coronary heart disease [mean age (74.6 ± 5.3) years, 66 males, 12 females] were investigated retrospectively. Three questionnaires about the quality of life, including Seattle Angina Questionnaire (SAQ), Nottingham Healthy Profile (Part Ⅰ NHP) and Duke Activity Status Index (DASD, were used to investigate patients before and after OPCAB. Results Prior to OPCAB, there was lower quality of life index in males than in females [SAQ: (65.3±5.1) vs. (69.5±8.1); NHP: (89.4±17.3) vs. (125.2±19.9), P＜0.01; DASI: (4. 1±1.1) vs. (4.3± 1.3)]. At the 12th months after OPCABG, there were significant improvements in all patients. The effects were less pronounced in females than in males [SAQ: (83.1 ±5.8) vs. (88.5±4.5), P＜0.05; NHP: (84.7± 11.7) vs.(91.4±13.7), P＜0.05; DASI: (4.7±1.4) vs. (5.4±1.1)]. Conclusions Our study shows that OPCAB improves quality of life in elderly patients with coronary heart disease. The benefits of OPCAB are even more pronounced in male patients.

Objective To investigate the relationship between 4G/5G polymorphism in the promotor of plasminogen activator inhibitor-1 (PAI-1) gene and pulmonary thromboembolism (PTE). And to detect whether it plays an important role in the pathogenesis of PTE. Methods The 76 patients with PTE, 74 gender and age matched healthy controls were recruited in this study. Genome DNA was extracted from whole blood using phenol-chloroform. Subjects were genotyped for the 4G/ 5G polymorphism of PAI-1 gene using polymerase chain reaction and restriction fragment length polymorphism analysis. Results Significant difference was found in the frequency of 4G/4G genotype between PTE group and control group (50.0% vs.24.3%,P<0.01). And there were no significant differences in 4G/5G and 5G/5G genotype between the two groups. The 4G allele frequency was higher in PTE group than in control group (72.4% vs. 55.4% , P<0.01) . The recessive allele model was informative and the odd ratio of 4G/4G genotype was much higher than of other two genotypes (OR=3.40, P<0.01). Further stratification showed 4G/4G genotype was associated with high risk of PTE for those individuals without traditional environment risk factors. Conclusions The 4G/5G polymorphism of PAI-1 gene is associated with PTE and 4G allele is recessive. 4G/4G genotype increases the risk of PTE for individuals who have no traditional risk factors of PTE.

Objective:To explore the intervention effect of humanistic management on anxiety and depression tendency of visiting physicians.Methods:The visiting physicians who began to further study in Beijing Anzhen Hospital, Capital Medical University from January 2016 to December 2018 were selected for humanistic management, and the visiting physicians from April 2013 to December 2015 were set as reference to conduct a questionnaire survey before and after the refresher training with the Hospital Anxiety and Depression Scale. Therefore, the visiting doctors all had the conventional refresher study management mode. On this basis, the intervention group established an individualized refresher study schedule, equipped the doctors with tutors, regularly visited the doctors and organized symposiums for them, assisted them to join the academic groups of the department, organized and coordinated the doctors to participate in the multi-disciplinary academic ward rounds, conducted negative emotional relief through the Balint groups, and integrated the cultural life of the refresher doctors into the cultural construction of the hospital and follow up the refresher doctors after the refresher training. SPSS 16.0 was used to perform t-test and variance analysis. Results:There was no difference in anxiety and depression scores between the two groups according to gender, type of refresher department, level of source hospital and length of study ( P > 0.05). Compared with the two evaluations in the intervention group, the second scores of anxiety for men and women [(5.90±1.37) vs . (6.48±1.87), (5.92±1.45) vs . (6.73±2.12)], doctors in each department [(5.50±1.23) vs . (6.76±2.35), (6.03±1.36) vs . (6.64±1.75), (5.98±1.50) vs . (6.64±2.15)], doctors from secondary and tertiary hospitals [(5.85±1.29) vs . (6.64±2.02), (6.00±1.50) vs . (6.78± 2.14)], the total score of doctors [(5.92±1.37) vs . (6.64±2.15), (5.92±1.47) vs . (6.68±1.98)] and the total score [(5.92±1.42) vs. (6.66±2.05)] were lower than the first evaluation score ( P<0.05). The second scores of depression for female doctors [(6.15±1.37) vs . (6.68±2.06)], doctors in medical laboratory department [(6.02±1.40) vs . (6.69±1.88)], doctors from tertiary hospital [(6.13±1.41) vs. (6.51±1.90)], doctor with different training durations [(6.04±1.42) vs . (6.50±2.02), (6.12±1.34) vs . (6.57±1.97)] and the total score of doctors [(6.09±1.37) vs . (6.54±1.99)] were lower than those of the first evaluation ( P < 0.05). The anxiety score of the second evaluation in the control group was higher in male physicians [(6.63±1.15) vs . (6.11±1.76)] than the first evaluation ( P < 0.05). Compared with the second evaluation data of doctors in the two groups, in terms of anxiety scores, the scores of doctors at all levels and total scores in the intervention group were lower than those in the control group ( P < 0.05); in terms of depression score, the scores of female visiting doctors, doctors from tertiary hospitals, doctors with refresher training duration of 6 months and total score were lower than those of the control group ( P < 0.05). Conclusion:The application of humanistic management to strengthen the management of refresher physicians can improve the psychological state of refresher doctors to a certain extent, especially alleviate the anxiety state, which is a worthy promotion of refresher management mode.

Objective     To explore the effect of aortic root perfusion of amiodarone when intractable ventricular fibrillation occurs during valve replacement. Methods     Totally 42 patients were selected as a drug group, who underwent intractable ventricular fibrillation following ascending aortic opening in valve replacement in Beijing Anzhen Hospital from October 2006 to October 2016. There were 26 males and 16 females with an average age of 56.31±12.56 years. The aorta was re-blocked when intractable ventricular fibrillation occured, amiodarone (150 mg diluted to 20 ml) through the aortic root perfusion tube was applicated, and suction was repeated 8-10 times with the cumulative amount of 150-200 ml, and then the ascending aorta was opened and fast compressed with a frequency of 200 times/min. While 53 patients with the same condition during the same period were selected as a control group. There were 35 males and 18 females with an average age of 58.79±19.81 years. The commonly used clinical treatment method of intractable ventricular fibrillation was adopted, such as continuous intravenous injection of 1 mg/kg lidocaine, while ascending aortic was re-blocked. The warm blood perfusion was given until the heart re-beated. The clinical outcomes were compared between the two groups.   Results     There was one perioperative death in the drug group and two deaths in the control group during perioperative period. Defibrillation frequency (3.11±0.59 times vs. 4.91±1.34 times, t=–2.917, P=0.000), heart rate 5 min after re-beating (91.65±9.81 beats/min vs. 98.32±10.21 beats/min, t=–2.019, P=0.032), cardiopulmonary bypass time (71.68±10.21 min vs. 81.59±12.93 min, t=–2.512, P=0.032), dopamine dosage (4.32±1.28 μg·kg–1·min–1 vs. 5.79±1.98 μg·kg–1·min–1, t=–2.781, P=0.015), epinephrine dosage (0.03±0.01 μg·kg–1·min–1 vs. 0.06±0.02 μg·kg–1·min–1, t=–3.996, P=0.000) and norepinephrine dosage (0.01±0.01 μg·kg–1·min–1 vs. 0.03±0.01 μg·kg–1·min–1, t=–4.163, P=0.000) of the drug group were significantly shorter or lower than those of the control group. The rate of cardiac rhythm 5 min after re-beating (42.8% vs. 9.4%, χ2=11.211, P=0.000) of the drug group was higher than that of the control group. Conclusion     During intractable ventricular fibrillation following ascending aortic opening in valve replacemen, re-blocking the aorta and amiodarone reperfusion of the aortic root can significantly improve the heart re-beating rate and avoid ventricular re-fibrillation, shorten the cardiopulmonary bypass time and reduce the dosage of inotropic drugs.

Objective    To explore the difference of myocardial injury between off-pump coronary artery bypass grafting (OPCAB) and modified perfusion on-pump coronary artery bypass grafting (ONCAB). Methods    A total of 558 patients who underwent coronary artery bypass grafting in Beijing Anzhen Hospital from 2017 to 2019 were included. According to whether or not they received modified perfusion cardiopulmonary bypass, all the 558 patients were divided into two groups including an OPCAB group (OP group) and an ONCAB group (ON group). There were 465 patients in the OP group including 282 males and 183 females with an average age of 63.58±7.87 years. In the ON group, there were 93 patients including 64 males and 29 females with an average age of 63.91±7.51 years. Creatine kinase MB (CK-MB) and cardiac specific troponin I (cTnI) were measured 24 hours before operation, 30 minutes after operation, 12 hours after operation, 36 hours after operation and 48 hours after operation. Results    No perioperative death occurred in all patients. CK-MB (5.00 ng/mL vs. 8.60 ng/mL, Z=–2.189, P=0.029) and cTnI (3.00 ng/mL vs. 7.80 ng/mL, Z=–5.307, P=0.000) in postoperative 12 hours in the ON group were less than those in the OP group. CK-MB (5.00 ng/mL vs. 5.60 ng/mL, Z=–2.280, P=0.023) and cTnI (0.10 ng/mL vs. 1.02 ng/mL, Z=–6.418, P=0.000) in postoperative 36 hours in the ON group were less than those in the OP group. cTnI (0.07 ng/mL vs. 0.81 ng/mL, Z=–1.946, P=0.032) in postoperative 48 hours in the ON group was less than that in the OP group. Conclusion    Compared with OPCAB, modified perfusion ONCAB has less myocardial damage. 

Objective    To explore the effect of whether or not to stop beating after conversion to cardio-pulmonary bypass (CPB) in off-pump coronary artery bypass grafting. Methods    From 2016 to 2018, 177 patients with off-pump coronary artery bypass grafting in Beijing Anzhen Hospital were transferred to CPB. According to whether they stopped beating after conversion to CPB during the operation, they were divided into two groups. A non-stop beating group: there were 76 patients with 45 males, 31 females. aged 63.53±6.98 years, who were not to stop beating after conversion to CPB. A stop beating group: there were 101 patients with 66 males and 35 females, aged 63.98 ± 8.37 years, who were to stop beating and underwent the modified perfusion and application of papaverine in perfusion after conversion to CPB. The clinical effect of the two groups was compared. Results    There were 14 deaths in the perioperative period. The mean graft flow (MGF) in the stop beating group was higher (P=0.033), and the pulse index (PI) was lower (P=0.001) than those in the non-stop beating group. Intra-aortic balloon counter pulsation (P=0.036), extracorporeal membrane oxygenation (P=0.038), continuous renal replacement therapy (P=0.014), ventilator-assisted time (P=0.021), ICU monitoring time (P=0.012), perioperative mortality (P=0.025) and the ejcetion fraction value (P=0.023) were significantly different between the groups. Conclusion    Compared with not to stop beating, those to stop beating can get better perioperative clinical effect after conversion to CPB, which is worthy of recommendation.

Objective    To investigate the influence of different discontinuation time of clopidogrel and aspirin before off-pump coronary artery bypass grafting on postoperative volume of drainage and blood products imported. Methods    A total of 454 patients who underwent coronary artery bypass grafting in Beijing Anzhen Hospital from January 2017 through December 2019 were included. According to the preoperative discontinuation of clopidogrel and aspirin, all the 454 patients were divided into three groups including a guide group, a non-stop group and a stop group. There were 86 patients in the guide group including 59 males and 27 females with an average age of 64.12±6.15 years. They continued to take aspirin 100 mg/d before operation, but stopped clopidogrel for more than 5 days. In the non-stop group, there were 234 patients including 141 males and 93 females with an average age of 63.71±7.01 years. They continued to take aspirin 100 mg/d before operation, and stopped clopidogrel <5 days. In the stop group, there were 134 patients including 76 males and 58 females with an average age of 62.90±7.78 years. They stopped aspirin and clopidogrel for more than 5 days before operation. The clinical effectiveness was compared among the three groups. Results    No perioperative death occurred in all patients. There was no statistical difference in platelet count, coagulation function, liver function, renal function, or myocardial markers among the groups (P>0.05). The hemoglobin [97 (15) g/ L vs. 98 (21) g/L vs. 100 (20) g/L, F=4.894, P=0.008] in the non-stop group was lower than that in the guide group and the non-stop group at 30 minutes postoperatively. The flow volume (399.87±127.19 mL vs. 367.05±125.89 mL vs. 349.63±130.68 mL, F=7.770, P=0.000) in the non-stop group at 3 hours postoperatively, the flow volume [600 (300) mL vs. 580 (245) mL vs. 550 (350) mL, Z=8.218, P=0.016] in the non-stop group at 6 hours postoperatively, the flow volume [750 (370) mL vs. 730 (350) mL vs. 730 (350) mL, Z=8.329, P=0.016] in the non-stop group at 12 hours postoperatively, the flow volume [890 (365) mL vs. 850 (340) mL vs. 850 (350) mL vs. Z=6.585, P=0.037] in the non-stop group at 24 hours postoperatively and the flow volume [950 (375) mL vs. 940 (360) mL vs. 940 (380) mL, Z=8.680, P=0.013] in the non-stop group at 48 hours postoperatively were more than those of the guide group and the stop group. The retention time of drainage tube was longer in the non-stop group [3 (1) d vs. 3 (1) d vs. 3 (1) d, Z=6.579, P=0.037] than in the guide group and the non-stop group. The amount of suspended erythrocytes input [0 (2) U vs. 0 (2) U vs. 0 (0) U, Z=6.150, P=0.046], and the amount of plasma input [200 (200) mL vs. 0 (200) mL vs. 0 (200) mL, F=4.144, P=0.016], the number of cases of plasma input (119 patients vs. 34 patients vs. 47 patients, Z=10.116, P=0.006) were more than those of the guide group and the stop group. Conclusion    Aspirin maintenance is recommended for patients before off-pump coronary artery bypass grafting. If not necessary, clopidogrel is discontinued for at least 5 days.
