Change and significance of fibrinolysis in coronary heart disease patients with angina pactoris

Objectives To study change and the clinical significance of fibrinolysis in coronary heart disease(CHD) patients with angina pactoris(AP).Methods Levels of plas-min plasminogen activator inhibitor-1(PAI-1),tissue-type plasminogen activator(t-PA),fibrinogen(FIB) in 110 CHD patients with AP and 20 normal cases as control group were analyzed in the same ways.Results Levels of PAI-1,FIB in CHD patients with AP were significantly higher than those in control cases,and those of t-PA were significantly lower than control cases;Levels of PAI-1,FIB in UA patients with UA heart events were significantly higher than those in patients with SA,and those of t-PA were significantly lower than patients with SA;Levels of PAI-1,FIB in patients with AP events were significantly higher than those in patients without AP events,and those of t-PA were significantly lower than patients without AP events.Conclusions There was abnormal of fibrinolysis function in CHD patients with AP, specially in patients with UA or with AP events,the abnormal of fibrinolysis might be play an important rule in coronary heart disease(CHD) patients with angina pactoris.

Effects of N-3 Fatty Acids on the Coronary Heart Disease Patients

Objectives To evaluate the effects of n-3 fatty acids on the coronary heart disease patients. Methods From September 2007 to March 2008, 60 patients with coronary heart disease were randomly assigned to n-3 fatty acids group (group N) and control group (group C). Both groups received standard coronary artery disease secondary prevention treatment and group N also received eicosapentaenoic acid (EPA) 1.8 g plus docosahexaenoic acid (DHA) 1.2 g per day for 12 weeks. Plasma triacylglycerols, total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) and blood pressure were measured before and after the study. Results Plasma triacylglycerols, blood pressure and LDL-C level were lower in group N after n-3 fatty acids treatment while no change was found in group C (P<0.05). HDL-C level slightly increased and total cholesterol level slightly decreased after n-3 fatty acids but both change were not significant (P>0.05). Conclusions N-3 fatty acids have beneficial effects on the coronary artery disease patients.

Feasibility of percutaneous coronary intervention via transulnar artery approachin selective patients with coronary heart disease

Objective To probe the clinic feasibility of percutaneous coronary intervention(PCI) via transulnar artery approach (PCI TRU).Methods Fourty patients with unstable ischemic manifestation(male 34,female 6;age 59.3 ±9.10 years)whose radial artery of right hand was thin with a weak pulse that was not suitable to transradial artery PCI while whose ulnar artery was thick with a strong pulse based on their larger diameter in ulnar artery as compared with those in radial artery ( 3.30 ±0.22mm vs 2.43 ±0.33 mm, P <0.05 ) by the investigation of vessel echography,but revesered Allen’s test for radial and ulnar artery was positive,were selected as the subjects for PCI TRU. The radio of ulnar artery versus radial artery was 1.35:1.00 and the time of Allen’s test in ulnar artery side was shorter than that in radial artery side ( 2.70 ±0.36 s vs 4.68 ±0.52s , P <0.05 ) before PCI. The efficiency of PCI TRU was evaluated. The time of manipulative duration for each procedure of PCI TRU was recorded. The time of Allen’s test, luminal diameter (mm) , cross area of vessel lumin (mm 2), blood velocity (Vs max), blood resistance (RI) in ulnar artery and radial artery and the level of blood oxygen in finger (PaO 2、SatO 2) were measured and recorded , respectively , as well were compared quantitatively before and after 1 month of procedure . Results Fourty eight lesion segments of 42 vessels in all patients were angioplasticized successfully via TRU by 6F guiding catheter including 23 segments of type B1 , 14 segments of type B2 and 11 segments of type C. PCI TRU in all of 40 patients was performed successfully. Fourty eight stents were implanted including 2 lesions of intrastent restenosis angioplasticized with cutting balloon technique before re stenting . The average time of manipulative duration of guiding catheters engaging in osicum of target coronary, crossing the vessel lesions of guidewire, dilatation and implantation of stents,and under X ray fluoroscopy were 4.30 ±0.59 min , 2.52 ±0.40min , 2.66 ±0.40 min ,and 25.9 ±0.49 min , respectively, and the total time of the whole procedure was 56.6 ±14.8 min . When the ulnar introducer was taken off, the access site in ulnar artery was suppressed by tourniquet with no bleeding in the access site and no limitation of physical activation under maintaining infusion of heparin immediately after procedure . There was no significant change in the diameter of ulnar artery and the time of Allen’s test after 1 month of PCI procedure as compared with those before procedure ( 3.22 ±0.48mm vs 3.26 ±0.22 mm , P >0.05 ; 2.96 ±0.98 s vs 2.72 ±0.47 s , P >0.05 ). No significant change was found in the parameters of blood velocity , cross area of vessel lumin, blood resistance and the level of blood oxygen in finger after 1 month of PCI procedure. The average total hospital stay was 5.21 ±0.43 days. Following up 1 month, no complications such as occlusion of ulnar artery, abnormal sensitivity and movement disability were found in right hands in all patients.Conclusions The ulnar artery might be selected as one approach of antebrachial artery for PCI in the patients with coronary heart disease whose radial artery was difficulty as access vessels of PCI, while reversed Allen’s test for radial and ulnar artery are positive and the luminal diameter of ulnar artery was larger than that of radial artery.

PLATELET ACTIVATION IN PATIENTS WITH CHRONIC PULMONARY HEART DISEASE EFFECT OF DIPYRIDAMOLE TREATMENT

Plasma levels of /f-thromboglobulin (/?-TG), platelet fac-tor 4(P and platelet aggregation rate (PAR) were measured in remission phase of 15 patients affected with chronic pulmonary heart disease (CPHD). 0-TG, /?-TG / PF4, PF4 and PAR were significantly higher in the patients than in controls (/3<0.01 and 0.05, respectively). After 10 days of treatment with Dipyridamole lOOtng tid, fi-TG, /?-TG / PF4 and PF4 decreased significantly compared with pretreatment values (/><0.01 and 0.05, respectively). The results suggest that in vivo platelet activation is indeed present in patients with CPHD and that dipyridamole can antagonize platelet activation in vivo.

Thinking on Treatment of Post-reperfusion Events in Patients with Coronary Heart Disease by Integrated Traditional Chinese and Western Medicine

In the 1970＇s, promoting blood circulation to remove blood stasis （PCRS） was the main method in integrative traditional Chinese and Western medicine （ICWM） in treating acute myocardial infarction （AMI）. It decreased the case fatality rate of AMI from 30% to 13%-16% as compared with that treated by simple Western internal medical conservative treatment. Later in the 1980＇s, such therapeutic approaches as infarction related arterial revascularization, thrombolysis and percutaneous coronary intervention （PCI） became the most effective means in treating AMI, which could re-canalize the obstructed coronary vessels, recover the blood perfusion of myocardium, and thus to save the ischemic myocardium, diminute the infarcted size, preserve the ventricular function and improve the patient＇s near and long-term prognosis, with the fatality rate reduced by 5%-7%. Hence, the some-time superiority of ICWM in treating AMI was overshadowed with no more luster left.

CLINICAL OUTCOMES OF 22 PEDIATRIC PATIENTS WITH CONGENITAL HEART DISEASE MANAGED WITH MECHANICAL CIRCULATORY SUPPORT AFTER CARDIAC SURGERY

Objective To investigate the clinical outcomes of children with congenital heart disease （CHD） requiring extracorporeal membrane oxygenation （ECMO） and left ventricular assist device （LVAD） support after cardiac surgery. Methods A total of 22 patients with CHD who required postcardiotomy mechanical circulatory support between March 2004 and March 2011 （85 months ） were analyzed retrospectively. Median age of the patients was 420 d （ 15 d - 4 years） and median weight was 3.4 kg （ 2 - 14. 5 kg ）. Eight patients were put on ECMO, while 14 patients were placed on LVAD. Results Thirteen （59%） patients died and 9 （41% ） survived to discharge. In survivals, the duration of LVAD and the duration of ECMO were both shorter than those of nonsurvivals （P 〈 O. 05）. The main complication was bleeding. Conclusion The earlier treatment and application of more advanced cardiac support devices for CHD patients are key factors for reducing complications.
