The Changes of Vasoactive Substances Originated Endotheiium in Patients with Unstable Angina Pectoris Treated by Improved Thrombolytic Therapy

Objectives To analyze the changes of vasoactive substances originated from endo- theiium in patients with unstable angina pectoris treated by modified thrombolytic therapy and explore the mech- anisms of the drug to treat unstable angina pectoris. Methods 120 patients with unstable angina pectoris who were not well responsed to common medication were studied. Their ECG stress tests were abnormal and there were ischemic changes in Holter. Urokinase 300,000 U was added in 100 ml normal saline and in- jected within 30 min once a day for 3 days. 300 mg as- pirin was administrated a day before and during uroki- nase applications. Before and after urokinase treat- ments , endothelin-1 , plasma tissue plasminogen activa- tor and its inhibitor-lwere determined. Results Compared with pretreatments, after treatments, the ac- tivities of tissue plasminogen activator increased, endo- thelin-1 and the inhibitor-1 decreased. The changes were significant. Conclusions Modified thrombolytic therapy can regulate the vasoactive substances origina- ted endotheiium in patients with unstable angina pecto- ris . The major substances include endothelin-1, plasma tissue plasminogen activator and inhibitor-1. This mechanism may suggest that urokinase can treat coro- nary heart disease effectively.

Changes in plaque stability, cell apoptosis and coagulation indexes after patients with unstable angina pectoris accept adjuvant salvianolate therapy

Objective:To investigate the effect of adjuvant salvianolate therapy on plaque stability, cell apoptosis and coagulation indexes in patients with unstable angina pectoris.Methods: 92 patients with unstable angina pectoris treated in our hospital between May 2011 and August 2015 were collected, and after the treatment process and auxiliary examination results were retrospectively analyzed, they were divided into the control group (n=45) who accepted conventional treatment and the observation group (n=47) who accepted adjuvant salvianolate treatment.

Effects of Ginkgo Leaf Extract on Function of Dendritic Cells and Th1/Th2 Cytokines in Patients with Unstable Angina Pectoris

Objective： To investigate the effects of Ginkgo leaf extract （GLE） on function of dendritic cells （DO） and Th1/Th2 cytokines in patients with unstable angina pectoris（UAP）. Methods： Fifty-four patients with UAP were equally assigned into two groups, the treated group and the control group, both treated with conventional Western medicine, but with GLE given additionally to the treated group. Blood of all patients was taken before and 4 weeks after treatment to prepare the peripheral mononuclear cells, then which were incubated in the completed medium containing granulocyte-macrophage colony stimulatory factor （GMCSF） and interleukin-4 （IL-4） to induce mature DO. The expression of co-stimulating factor CD86 （B7-2） on the surface of DC was detected by flow cytometry, and the stimulating capacity of DC was determined by mixed lymphocyte reaction （MLR）. The blood levels of cytokines, interferon-γ （IFN-γ）, and IL-4, were analyzed by ELISA, and blood C-reactive protein （CRP） level by turbidimetry. Moreover, the direct effect of Ginkgolide B on CD86 expression on DO were also tested in vitro. Results： After treatment, CD86 expression on DO, the stimulating capacity of DO as well as levels of IFN-γ and ORP were lowered in both groups （P〈0.05 or P〈0.01）, but the changes were much more significant in the treated group than those in the control group. Ginkgolide B showed a direct inhibitory effect on the CD86 expression on DO. Conclusion： The inhibition of GLE on DO and thereby the suppression on inflammatory reaction may be one of the mechanisms of GLE in treating patients with UAP.

EFFECTS OF EXERCISE ON THE FIBRINOLYTIC ACTIVITY INPATIENTS WITH UNSTABLE ANGINA PECTORIS

Objective The purpose of this study was to evaluate the fibrinolytic response to exercise in patients with unstable angina pectoris(UAP) compared with an age - matched control group. Methods We measuredtissure- type plasminogen activator (t- PA) activity and plasminogen activator inhibitor 1(PAI- 1) activitybefore and after treadmill exercise test in 20 healthy subjects and 25 patients with UAP. ResultsResting t - PA activities were similar between two groups, but resting PAI- 1 activity was higher in UAP groupthan in control. Although both groups showed significant increase in t- PA activity with exercise, post - exerciset - PA activity was significantly lower in patients with UAP than in control (0.96± 0.45IU/ml vs 1.89± 0.68I U/ml,P<0.01), Post - exercise PAI- 1 activity was still much higher in UAP group than in control (8.20±2.28A U/ml vs4.21± 0.68A U/ml, P<0.01). Conclusion There existed impaired fibrinolysis in patients with UAP not only at restbut also alter exercise loading.

Effect of Chinese Herbs for Activating Blood Circulation,Removing Stasis and Supplementing Qi on the Circulating Endothelial Cells in Patients with Unstable Angina Pectoris

Objective: To observe the effect and clinical significance of circulating endothelial cells (CEC) in the pathogenesis of coronary heart disease with unstable angina pectoris (CHD-UAP), and to explore the protective effect of Chinese herbs for activating blood circulation, removing stasis and supplementing Qi (CH) on CHD-UAP patient's CEC. Methods: Sixty patients with diagnosis of CHD-UAP confirmed and differentiated to be Qi-deficiency and blood stasis by TCM were randomly divided into two groups and treated, on the basis of Western drug-therapy, with Tongxinluo capsule (通心络胶囊, TXL) and Huoxue Tongmai capsule (活血通脉胶囊, HXTM) respectively by way of oral taking three times a day, 3 capsules every time, with 1 month as one therapeutic course. The number of CEC in patients' blood circulation was counted before and after treatment. Besides, the number of CEC in 30 healthy persons was also counted for control. Results: The number of CEC in CHD-UAP patients was significantly higher than that in the healthy persons (P<0.01). After the patients were treated with CH, either TXL or HXTM, it significantly decreased (P<0.01)with insignificant difference between the two treated groups. Conclusion: CEC in CHD-UAP patients is severely damaged and endothelial function in disorder, Chinese herbs have protective effect on patients' CEC.

Comparative Study on the Effects of Small Dose of Aspirin Combined with Ginkgo-damole Injection(银杏达莫注射液) and the Effects of Conventional Dose of Aspirin in Treating Senile Unstable Angina Pectoris

Objective: To evaluate the therapeutic and adverse effect of small dose of aspirin (Asp) combined with Ginkgo-damole injection (GDI,银杏达莫注射液) in treating senile unstable angina pectoris (UA). Methods: One hundred and twenty old in-patients of coronary heart disease with UA were randomly divided into two groups. The 60 patients in the treated group were treated with oral administration of enteric soluble 50 mg Asp once a day and GDI 20 ml per day by intravenous dripping, with 14 days as one therapeutic course, while the other 60 in the control group were treated with enteric soluble Asp 100 mg alone once a day orally. Besides, isosorbide-5-mononitrate 20 mg twice a day was applied to both groups, and the β-ad-renoceptor blocker, blood lipids regulatory agents and nitroglycerin (10 mg by intravenous dripping) were given accordingly. The angina total improving rate, hemorrheologic indexes (whole blood viscosity, plasma viscosity, fibrinogen, platelet aggregation rate), comprehensive clinical terminal event and the total occurrence rate of adverse reaction in the two groups were observed. Results: After treatment, comparison between the two groups showed insignificant difference in aspects of angina total improving rate (75.00% vs 65.00%), hemorrheological indexes and comprehensive clinical terminal event rate (25.00% vs 31.67%), P>0.05, and the hemorrheological indexes were improved in both groups (P<0.05), but the total occurrence rate of adverse reaction in the treated group was lower than that in the control group (6. 67% vs 25.00%), showing significant difference (P<0.05). Conclusion: In treatment of senile UA, small dose of Asp combined with GDI showed therapeutic effect similar to that of conventional dose of Asp, but it has lower adverse reaction.

The Study of hemodynamics and coronary arteriography of Patients with Different Types of Unstable Angina Pectoris

Objectives To explore the basic heart functional state and cardiac reserve function of patients with different types of unstable angina pectoris (UAP) and observe the relations between the heart function and severity of coronary arterial disease. Methods 70 cases with UAP were enrolled including 25 patients with angina decubitus (AD), 23 patients with mixed angina (MA) , and 22 patients with accelerated effort angina (AEA). All patients underwent a series of examination such as UCG, ECT, hemodynamics and volume-loading test. The patients were divided into three groups in light of the results of the hemodynamic examination: ① diastolic dysfunction group ② systolic dysfunction group ③ normal heart function group. We assessed the basic heart function and cardiac reserve function of patients with different types of UAP and also observed the relations between coronary arteriography and heart function. Results ① Under basic conditions, patients with angina decubitus suffered from the systolic (36%) or diastolic dysfunction (48%). 43 percent of the patients with mixed angina had systolic dysfunction and other 43 percent of them had normal cardiac function. However, patients with accelerated effort angina (AEA) were characterized by diastolic dysfunction (31%) or normal heart function (60%). ② In hemodynamic examination, the pulmonary capillary wedge pressure of positive patients rose, at the same time cardiac index fell to the extreme instantaneously after loading in volume-loading test and then they restored to the basic level until 60 minutes. However, both PCWP and CI of the negative patients reach the peak momentarily after loading. They returned to the basic level within 30 minutes. ③ coronary arteriography show: there are 41% of patient with three-vessel disease, 50% with two-vessel disease, 9% single vessel disease and left main narrowing 22. 7% in AEA. There are separately 76%, 24%, 0% and 36% in AD; and 26.1% , 43.4% , 21.7% , 43.4% in MA. ④ Constituent ratio of the AEA and MA were separately compared with AD, AEA/AD: P < 0.05(P = 0.031); MA/AD: P < 0.01 (P = 0.000313). Conclusions Most of patients with the above three types of unstable angina pectoris suffered from the basic heart dysfunction and cardiac reserve dysfunction which might participate in the occurrence and development of unstable angina pectoris. In angiography, there are the most three-vessel diseases in AD that are, therefore, the most severe UAP.

Relationship Between Serum Creatine Kinase Isoenzyme MM Subbands and the Gradation of Coronary Stenosis in Patients with Unstable Angina Pectoris

Objective To observe the relationship between serum creatine kinase isoenzyme MM sub-bands (CKMM3/MM1 ratio) and the gradation of coronary stenosis and provide a simple, reliable, and economical method for identifying high-risk unstable angina pectoris (UAP). Mehtods Blood samples were drawn at different time after onset of chest pain in 21 patients with UAP and only once in 20 each volunteers for control. CKMM3/MM1 ratio was detected by nonserial buffer agarose gel electrophoresis. CKMB and CK were observed by velocity method. An emergent coronary arteriography was performed as soon as patients were admitted into hospital. Results Patients with UAP were divided into two subgroups: patients with elevated serum enzyme [P( + )] and patients with normal serum enzyme [P( - ) ] according to CKMM3/MM1 ratio < 0. 5. Patients with UAP( + ) had higher serum CKMM3/MM1 ratios from 0.5 to 12hrs and serum CKMB from 2 to 12 hrs than those with UAP( - ) and control ( P < 0. 05) . Serum enzyme concentrations of patients with UAP whose coronary lumen had 90% or more than 90% stenosis were significantly higher than those whose coronary lumen had less than 90% stenosis ( P <0. 01) . Any CK-MM3/MM1 ratio was less than 1. 0 and CK within the normal range in patients with UAP( + ) group. Conclusions CKMM3/MM1 ratios in patients with UAP can reflect severity of myocardial ischemia. SerumCKMM3/MM1 ratio provides a simple, reliable, and economical method for identifying high-risk UAP.

Results: Before treatment, the differences in serum levels of endothelial function indexes, blood viscosity indexes and lipid metabolism indexes were not statistically significant between the two groups. After 3 months of treatment, serum NO level of research group was higher than that of control group while ET-1 level was lower than that of control group;serum blood viscosity index TXB2 content of research group was lower than that of control group while PGI2 content was higher than that of control group;serum lipid metabolism indexes TG, TC and LDL-C contents of research group were lower than those of control group while HDL-C content was higher than that of control group. Conclusion: Yixinkangtai Capsule combined with diltiazem therapy can effectively optimize the endothelial function, reduce the blood viscosity and balance the lipid metabolism in patients with unstable angina pectoris.

Study on Effect of Zhixinkang Capsule(脂欣康胶囊)in TreatingUnstable Effort Angina and Hyperlipidemia and Its Function in Vascular Endothelium Protection

Objective:To observe the clinical effect and protection of vascular endothelium of Zhixin-kang Capsule (ZXKC) in middle-aged and old people with unstable effort angina and hyperlipidemia. Methods: Sixty-five patients with unstable effort angina were randomly divided into ZXKC group (34 cases) and control group (31 cases). Conventional western medical therapy was given to both groups, with ZXKC group receiving additional ZXKC treatment. Data of 20 healthy persons were taken as normal group. Forty-eight patients with hyperlipidemia were divided into ZXKC group treated with ZXKC (31 cases) and control group treated with Yixintong (17 cases). The changes of clinical symptoms and laboratory indexes in all the patients were observed before and after treatment. Results: In patients with unstable effort angina, the efficacy of treatment of ZXKC, the withdrawal rate of nitroglycerin, the relieving of symptoms, the improvement of the electrocardiogram, the counts of circulating endothelial cells, the content of platelet P-selectin, the content of plasma endothelin (ET), the activity of superoxide dismutase (SOD) and the activity of malonyldialdehyde (MDA) were all better than those in the control group. In patients with hyperlipidemia, there was no significant difference in lipids reduction between ZXKC group and the control group. In both groups, the total cholesterol (TC), triglyceride (TG), low density lipo-protein-cholesterol (LDL-C), lipoprotein(a) [Lp(a)] , ET, oxidized low density lipoprotein, MDA, arte-riosclerotic index (AI) all lowered obviously, while the SOD, HDL-C and calcitonin gene-related peptide (CGRP) were all elevated markedly. In the ZXKC group, the nitric oxide(NO) increased significantly whereas the ET/CGRP and ET/NO decreased markedly. The total effective rate in symptom relieving, the markedly effective rate, the reduction of TC, ET and ET/CGRP, and the elevation of SOD in ZXKC group were all superior to those in the control group. Conclusion: ZXKC could effectively resist myocardial ischemia, relieve angina, reduce blood lipids, protect vascular endothelial cells, inhibit the activation of platelets, and resist lipid peroxidation.

Management of unstable angina in a patient with Haemophilia A

Hemophilia A is an X-linked recessive disorder characterized by a deficiency of coagulation factor Ⅷ(FⅧ) and therefore by a greater risk of bleeding during percutaneous interventional procedures and during the dual antiplatelet therapy(DAPT) in patients with ischemic heart disease. Information regarding safe percutaneous procedures in hemophiliacs is limited. Since the introduction of FVⅧ concentrates, the life expectancy of hemophiliac patients has improved and consequently, the rate of ischemic heart disease in this population is increased. Frequently the replacement therapy can trigger the onset of an acute coronary syndrome. We report a case of a patient with mild Hemophilia A, who presents with unstable angina, treated successfully with coronary angioplasty and drug eluting stent implantation without replacement of FVⅧ, treated with long term DAPT without major bleeding after six months of follow up.

The renal and platelet functions and monitorsinpatients with unstable angina pectoris and diabetes mellitus undergoing interventional therapy with or without the treatment of alprostadil

Background Patients with unstable angina pectoris and diabetes mellitus are very common. When they receive interventional therapy, contrast agentscan causerenal injuryand platelet activation. Alprostadil has been shown to decrease inflammation and microvascular resistance. There is no any report on the protection effects of alprostadilon renal injuryand the platelet activation during cardiac interventional therapy. Methods A total of 57 patients were divided into two groups, alprostadil group （n=35） and normal group n=22）. BUN （blood urea ni- trogen） and SCr （serum creatine） were measured as the renal function parameters. GFR （glomerular filtration rate） was calculated by the MDRD formula. Platelet parameters： PLT （platelet count, 109）, PDW （platelet distribu- tion width, fL）, MPV （mean platelet volume, fL）, PLCR （large platelet scale ratio, %） were measured as the platelet activationindex. T test and Chi-square test were used as statistical methods, and P〈0.05 was considered statistically significant. Results In the alprostadil group, SCr was 71.1±13.8 μmoFL and 65.9±12.6 ＆tool/L, before and after interventional therapy （P〈0.05）. BUN was 5.68±1.79 mmol/L and 3.86±1.19 mmol/L （P〈0.001）, before and after interventional therapy. I n the platelet tests, MPV was seemed to be the only useful platelet parameter, before and after interventional therapy （11.8±1.8 fL and ll.l±1.2fL, P〈0.05）, while the PLT （109/L）, PDW （fl）, PLCR （%） didn＇ t show any significant difference. In the normal group, all these tests＇ results didn＇ t significantly change after interventional therapy. Conclusions The patients with the unstable angina pectoris and diabetes mellitus have on the risk of renal function damage and platelet activation when undertaking cardiac interventional therapy. Alprostadil protects renal function and alleviates olatelet activation.

New Developments in Anti-Anginal Therapy: Roles of Ivabradine, Allopurinol and of Agents Modifying Myocardial Metabolism

Over the last 20 years, it has emerged that, while surgical revascularisation of extensive ischaemic heart disease may have prognostic advantages, the main issues considered regarding individual management are usually those of symptomatic improvement only. The major impetus towards invasive intervention is therefore failure of prophylactic anti-anginal therapy. On the other hand, many patients, especially the elderly, now present the clinical problem of ongoing angina without residual invasive options. There is an ongoing need for more effective anti-anginal therapies. Of the currently available major classes of prophylactic anti-anginal agents, neither nitrates, β-blockers nor calcium antagonists generally produce marked improvements in exercise duration. Three areas of new therapeutic development in anti-anginal therapy are worthy of note. These involve the sinus node inhibitor ivabradine, high dose allopurinol (xanthine oxidase inhibitor) and a new class of “metabolic modulators” represented by perhexiline, trimetazidine and probably ranolazine. The current review addresses the therapeutic potential of these agents. Notably, all of these “new” drugs are potentially suitable for management of angina in the setting of impaired left ventricular systolic function, and they may also be utilized in patients with angina independent of the presence of coronary disease (for example in hypertrophic cardiomyopathy). The current evidence for efficacy and potential future development in this area are reviewed.

Effects of systematic cardiac rehabilitation training in elderly patients with unstable angina following cardiac stent implantation

BACKGROUND Coronary stent implantation is usually used to treat unstable angina to alleviate stenosis or occlusion,promoting blood flow restoration and alleviating symptoms such as myocardial ischemia.And postoperative cardiac rehabilitation is essential for enhancing recovery and prognosis.Nevertheless,conventional rehabilitation lacks specificity,particularly for elderly patients with multiple comorbidities and poor compliance,rendering it less effective.AIM To investigate the effects of systematic cardiac rehabilitation training in elderly patients with unstable angina following coronary stenting intervention.METHODS A retrospective enrollment was conducted comprising fifty-four elderly patients with unstable angina pectoris who underwent systematic cardiac rehabilitation training after receiving coronary intervention as the rehabilitation group,while fifty-three elderly patients who received basic nursing and rehabilitation guidance measures after coronary intervention were assigned to the control group.Differences in Seattle Angina Questionnaire scores,survival quality(SF-36)scores,cardiopulmonary exercise function assessment index,echocardiographic cardiac function index,and adverse cardiovascular events were compared between the two groups.RESULTS After intervention,the rehabilitation group observed greater VO2 Max,maximum metabolic equivalent,eft ventricular ejection fraction,left ventricular end-diastolic diameter and smaller left ventricular end-systolic diameter.And the rehabilitation group observed greater scores of physical activity limitation,stable angina pectoris,treatment satisfaction,and SF-36 score.The incidence of adverse cardiovascular events in the two groups,showed no significant difference.CONCLUSION Systematic cardiac rehabilitation following coronary stenting in elderly patients with unstable angina pectoris can enhance cardiac function recovery,consequently enhancing both quality of life and cardiopulmonary exercise tolerance.
