With the wide application of percutaneous coronary intervention (PCI) in patients with coronary heart disease (CHD), it is a popularly concerned problem within clinical doctors to promote the patients' early recovery and improve their health related quality of life (HR-QoL).

OBJECTIVETo study the effect of Suxiao Jiuxinwan on angiogenesis in experimental myocardial infarction rats.

METHODThe animal model was established by ligation of anterior decending coronary artery and the infarction areas as well as microvascular density (MVD) in the marginal infarction area of the myocardial infarction rats were observed.

RESULTInfarction areas in high dose and low dose Suxiao Jiuxinwan groups were significantly different from that of model group (P<0.01), and this effect was similar with the positive model group and had the dosage-dependent speciality. The microvascular density (MVD) of marginal infarction areas in Suxiao Jiuxinwan high and low groups was much more elevated than that in the sham group (P<0.05), and the effect of Suxiao Jiuxinwan high group was similar with that of the positive control group. But the difference between the Suxiao Jiuxinwan high and the low goups was not significant.

CONCLUSIONSuxiao Jiuxinwan has the obvious effcet on angiogenesis in eperimental myocardial infarction rats.

This study was aimed to investigate the effects of Shen-Y uan Y i-Qi Huo-Xue (SYYQHX) capsule com-bined with early percutaneous coronary intervention (PCI) on near-term quality of life (QOL) in unstable angina (UA) patients. Seventy-eight patients diagnosed with UA were selected and randomly divided into the treatment group and control group, with 39 patients in each group. Early PCI was undergone after coronary angiography. Before PCI, the control group was given routine western medication. The treatment group was given routine western medication plus SYYQHX capsule, three pills once, three times daily. The treatment lasted for 30 days. The QOL scores were evalu-ated among patients from both groups before and after treatment in order to determine the efficacy on angina, electro-cardiogram (ECG) and traditional Chinese medicine (TCM) main symptom. The results showed that compared to pre-treatment, the scores of physical limitation (PL), angina stability (AS), angina frequency (AF), and treatment satisfac-tion ( TS ) were significantly increased after treatment ( P < 0 . 05 ) . Compared with the control group , after treat-ment with SYYQHX capsule, the AF, duration time and symptoms of palpitation, fatigue and shortness of breath were obviously improved (P< 0.05). The scores of AS, AF and TS in the treatment group were significantly increased (P < 0.05). It was concluded that SYYQHX capsule combined with early PCI can improve the near-term QOL and TCM main symptoms among UA patients.
