Which patients with coronary artery disease should include oral nitrates on their discharge medication list?

BACKGROUND: Which patients with coronary artery disease (CAD) should have oral nitrates on their discharge medication list after coronary angiography (CAG)? To assess the relationship between oral nitrates included in the discharge medication list and major adverse cardiovascular events (MACEs) among CAD patients, we designed this retrospective cohort study. METHODS: A total of 2979 CAD patients hospitalised in the Department of Cardiology, Affiliated Hospital of Jining Medical University from May 2013 to October 2015 were enrolled, grouped according to whether oral nitrates were included at discharge after CAG, and followed up for MACEs for a mean of 4.42 years after discharge. The primary endpoint was MACEs. Multivariate Cox proportional hazards models were used to analyses potential confounding factors. Stratified analysis was used to observe the relationship between oral nitrates and MACEs by different covariates. RESULTS: The median follow-up time was 4.61 years, and 296 (9.94%) patients experienced MACEs. Multivariate Cox proportional hazards model analysis showed no association between oral nitrates on the discharge medication list and the occurrence of MACEs among patients with CAD (p > 0.05) after adjusting for some covariates, such as SYNTAX score (hazard ratio (HR): 1.18, 95% confidence interval (CI): 0.90-1.55, p = 0.2420). Stratified analysis revealed a higher incidence of MACEs among hypertensive patients prescribed oral nitrates at discharge (HR: 1.67, 95% confidence CI: 1.13-2.46, p = 0.0046). However, prescribing nitrates at discharge for patients with low uric acid levels increased the incidence of MACEs, which showed a possible trend towards significance (HR: 1.44, 95% CI: 0.99-2.09, p = 0.0525). CONCLUSION: There was no association between oral nitrates included in the discharge medication list and the development of MACEs among patients with CAD after adjusting for some covariates, such as SYNTAX score. Oral nitrates after discharge for CAD patients combined with hypertension increased the occurrence of MACEs. Oral nitrates after discharge for CAD patients combined with low uric acid levels may increase theoccurrence of MACEs, and close monitoring for any adverse events is recommended.

Clinical nursing path teaching application in teaching children with mycoplasma pneumonia / 中华医学教育探索杂志

Objective To explore the clinical nursing path teaching method application in children with mycoplasma pneumonia and its effect.Methods 93 higher vocational nursing students of two classes of Grade 2011 were chosen as the subjects,one class as the experimental group(46),and the other class as the control group(47).The traditional teaching method was used in the control group,while method of clinical nursing path was used in the experimental group.Two groups of nursing students were given closed book exams and questionnaires to evaluate teaching effectiveness of the two groups.SPSS 13.0 was used for statistical analysis,count data using x2 test,measurement data using t-test,test level α=0.05.Results The experimental group students' test scores were significantly higher than the control group(85.26 ± 3.57)vs.(76.39 ± 4.16),and the difference was statistically significant P=-0.02.The survey showed that there were more students in the experimental group than in the control group who made a positive comment on the questionnaire's role in helping improve students'learning autonomy,their critical thinking ability,and promote their grasp of the content of the disease.Conclusion Clinical nursing path teaching method as a new kind of teaching method,can improve the teaching effect.

The effect of trimetazidine on alcoholic cardiomyopathy and plasma brain natriuretic peptide / 中国医师进修杂志

Objective To observe the effect of conventional therapy plus trimetazidine on alcoholic cardiomyopathy (ACM) and plasma brain natriuretic peptide (BNP).Methods Eighty-six cases of ACM patients were divided into control group and observation group by random digits table method with 43 cases each.Control group was treated with conventional therapy,while observation group was added trimetazidine.Course of treatment was 3 months.The left ventricular ejection fraction (LVEF),left ventricular end diastolic diameter (LVEDD),6 min walk distance,plasma BNP before and after treatment and the efficiency in two groups was observed and compared.Results LVEF,LVEDD,6 min walk distance,BNP before treatment in control group were respectively (37.2 ±7.4)％,(57.6 ±7.4) mm,(312.8 ±21.6) m,(846.2 ±63.7)μg/L,and the indicators in observation group were respectively (38.5 ±8.1)％,(57.1 ±6.8) mm,(316.5 ± 23.9) m,(857.6 ± 61.4) μ g/L.All indicators between two groups was no statistically different (P＞0.05).LVEF,LVEDD,6 min walk distance,BNP after treatment in control group were respectively (43.5 ±8.6)％,(54.3 ± 6.4) mm,(511.6 ± 26.7) m,(679.4 ± 51.3) μg/L,and there were significant difference compared with those before treatment (P ＜ 0.05).LVEF,LVEDD,6 min walk distance,BNP after treatment in observation group were respectively (51.6 ± 9.2)％,(51.2 ± 6.3) mm,(579.3 ± 25.1) m,(536.5 ± 50.6)μ g/L,and there were significant difference compared with those before treatment (P ＜ 0.05).There were significant difference in LVEF,LVEDD,6 min walk distance and BNP after treatment between two groups (P ＜ 0.05).The total effective rate in observation group was 90.7％ (39/43),which was significantly higher than that in control group [72.1％ (31/43)] (x2 =4.914,P ＜ 0.05).Conclusion Adding trimetazidine on the basis of conventional therapy can improve the cardiac function and myocardial remodeling of ACM patients and improve clinical efficacy.

Relationship between the polymorphism of the AT2R gene 1675A/G and the effect of indapamide sustained release tablets in female hypertension patients / 中国综合临床

Objective To investigate the relationship of the1675A/G polymorphism of AT2 gene with the therapeutic effect of indapamide sustained release tablets in female patients with primary hypertension.Methods Two hundred and twenty female patients with primary hypertension were treated with Indapamide Sustained Release Tablets ( 1.5 mg · qd) for 8 weeks.The blood samples from the patients were collect to determine AT2 gene polymorphism by PCR combined with HRM and sequencing.Results Two hundred and five patients completed the test.In female patients,the therapeutic efficacy of indapamide sustained telease tablets among different AT2R genotypes( AA:70.6％,AG:71.6％,GG:71.4％ ) showed no significant difference ( x2=2.53,P=0.49 ),neither do the decline of BP after therapy ( F=0.39 and 0.19 respecrively,P ＞ 0.05).Conclusion The AT2 genotype was assumed to be not correlated to the blood pressure lowering response to Indapamide Sustained Release Tablets in female primary hypertension patients.
