Methods: A total of 150 patients with unstable angina pectoris who were treated in the hospital between February 2014 and February 2017 were divided into the control group (n=75) and the research group (n=75) according to the random number table method. Control group received clinical conventional therapy, research group received Yixinkangtai Capsule combined with diltiazem therapy on the basis of conventional therapy, and both groups received 3 months of treatment. Differences in endothelial function, blood viscosity and lipid metabolism were compared between the two groups of patients before and after treatment. 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.展开更多

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.展开更多

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.展开更多
