急性心肌梗死患者血清新蝶呤的变化及其预后判断价值

目的:探讨心肌梗死急性期血清新蝶呤(Neopterin,Npt)的变化及其预后判断价值。方法:以86例急性心肌梗死(AMI)患者为对象,与88例不稳定型心绞痛(UAP)、62例稳定型心绞痛(SAP)及35例健康者行对照观察。检测两组血Npt水平(AMI、UAP患者测定入院时、3d后和出院前3个时点,SAP与健康者为单次检测),记录AMI组住院及随访期间(11～13个月,平均11.2个月)心脏性死亡、再发性梗死、心绞痛等事件发生情况。结果:AMI组Npt阳性率及平均水平明显高于UAP、SAP及健康者(均P<0.01)。AMI患者入院时及3d后血Npt相似,均明显高于出院前(P<0.01)。血Npt阳性者,住院及随访期间心脏事件发生率显著高于Npt阴性者(P<0.05)。但有与无事件发生者,入院时、3d后、出院前3个时点血Npt水平比较,仅出院前差异有统计学意义(P<0.01)。经校正其他因素后,3个时点血Npt对AMI患者事件发生的相对危险度(95%可信区间)分别为4.7(0.6～36.3,P>0.05)、4.2(0.8～5.1,P>0.05)、7.2(1.8～29.6,P<0.01)。结论:AMI急性期血Npt明显升高,病情稳定后逐渐下降,此时的水平反映了不稳定斑块的炎症活动状况,是AMI患者预后的独立预测因子。

Antithrombotic treatment and the incidence of angina pectoris

BACKGROUND: In primary prevention, anticoagulation with warfarin sodium to an international normalized ratio of 1.5 and 75 mg of aspirin per day each reduced the incidence of coronary heart disease (CHD). Effects on the development of angina pectoris and total CHD (resulting from angina, myocardial infarction, and coronary death) have been assessed, particularly in light of recent evidence that warfarin may have a "durable effect" on CHD through effects on the pathologic condition of the vessel walls involved. METHODS: The Thrombosis Prevention Trial was carried out in 5499 men aged 45 through 69 years who were at increased risk of CHD. The trial was factorial, with 1 group taking active warfarin and active aspirin, 1 taking active warfarin and placebo aspirin, 1 taking placebo warfarin and active aspirin, and 1 taking double placebo treatment. In addition to those with myocardial infarction and coronary death, men developing angina pectoris after entry to the trial were identified. RESULTS: Warfarin appeared to reduce the incidence of stable angina by 16% (95% confidence interval [CI], -14 to 38), although not significantly (P =.26), while aspirin increased the incidence by 39% (95% CI, 0 to 91) (P =.05). The incidence of stable angina was 37% (95% CI, -1 to 60) less in those taking warfarin than in those taking aspirin (P =.05). Warfarin reduced total CHD by 18% (95% CI, 4 to 30) (P =.01), while the reduction due to aspirin was 8% (95% CI, -10 to 22) (P =.36). CONCLUSIONS: The results are compatible with the concept of a durable effect of warfarin on the chronic pathologic conditions underlying angina, although this has not been established with certainty. Further research is needed to confirm or refute our findings, because they carry potentially important implications for the primary prevention of CHD with the use of antithrombotic agents.

Superiority of warfarin over aspirin long term after thrombolytic therapy for acute myocardial infarction

Results of recent clinical trials have unequivocally established the value of intravenous thrombolytic therapy in enhancing survival after acute myocardial infarction. However, the optimum long-term antithrombolytic strategy for prevention of recurrent cardiac complications after thrombolysis is unknown at the current time. To determine whether aspirin or warfarin best prevents postdischarge recurrent cardiac events (unstable angina, reinfarction, pulmonary edema, or/and death), we analyzed the long-term course of 203 patients at our institution who received intravenous thrombolytic therapy (streptokinase, tissue plasminogen activator, or urokinase) for acute myocardial infarction. Of these, 129 (64%) survived to hospital discharge without revascularization--92 patients (71%) received aspirin (325 mg/day). whereas 37 (29%) received warfarin. The choice of drug was made by the treating physician. By a mean of 2.5 years of follow-up, 34 of 92 patients receiving aspirin (37%) versus 6 or 37 receiving warfarin (16%) (p less than or equal to 0.02) had unstable angina, reinfarction, pulmonary edema, and/or death. No life-threatening hemorrhage occurred in either group. Warfarin appears to be superior to aspirin long term in patients with postlysis myocardial infarction for the prevention of recurrent cardiac complications.     

Echocardiographic determination of left atrial function and its application for assessment of mitral flow velocity pattern

Forty-three patients presenting with unstable angina or myocardial infarction were randomised double blind to warfarin [target international normalised ratio (INR), 2.0 to 2.5] and aspirin (150 mg) daily or placebo plus aspirin (150 mg) daily. Coronary flow was assessed with the thrombolysis in myocardial infarction (TIMI) flow grade and corrected TIMI frame count (CTFC). Coronary artery flow was reduced (higher CTFC) at baseline in culprit arteries (mean +/-SD, 37.1+/-15.4 frames) compared to nonculprit arteries (22.5+/-6.7 frames, P<0.0001). In patients with a patent artery at follow-up, coronary flow was unchanged after ten weeks of warfarin and aspirin (-2.0+/-19.9 frames) or aspirin alone (3.8+/-10.4 frames, P = 0.20). Patients randomised to aspirin alone were more likely to progress to total occlusion [aspirin, 7 of 19 (37%) vs. warfarin and aspirin, 1 of 24 (4%); P = 0.01). Higher baseline culprit artery CTFC was also associated with an increased risk of late occlusion [+10 frames; odds ratio (OR), 1.65; 95% CI, 1.01 to 2.33]. Coronary flow remained impaired ten weeks after presentation with myocardial infarction or unstable angina. Combination warfarin and aspirin therapy did not improve flow in vessels that remained patent but did reduce the risk of progression to occlusion.     

Prognostic value of C-reactive protein and troponin T level in patients with unstable angina pectoris

OBJECTIVES: The prognosis of unstable angina pectoris may be more accurately predicted by the combination of C-reactive protein (CRP), which is a known inflammation marker, and troponin T (TnT), which is used for risk assessment for the prognosis of acute coronary syndrome. The present study investigated the correlations between pathophysiology and prognosis of severe unstable angina pectoris and CRP and TnT levels. METHODS: The correlation between CRP at admission and the prognosis was studied in 367 patients with severe unstable angina pectoris (Braunwald type II and III) who were admitted to our hospital between January 1998 and December 2000. The in-hospital and long-term prognosis was investigated in TnT-positive patients. In-hospital cardiac events were defined as death, myocardial infarction, heart failure and angina attacks during hospitalization. Long-term cardiac events were defined as death, myocardial infarction, heart failure and recurrence of angina. RESULTS: The incidence of in-hospital cardiac events in all patients was 30.2%. The CRP levels were higher in patients with cardiac events (0.97 +/- 2.67 vs 0.53 +/- 1.29 mg/d/, p = 0.057), but there was no significant difference between the two groups. The incidence of long-term cardiac events was 26.8%. The mean CRP level was significantly higher in patients with cardiac events than in patients without cardiac events (1.17 +/- 1.86 vs 0.43 +/- 1.14 mg/dl, p = 0.098). In TnT-positive patients (TnT > 0.1 ng/ml, 23% of all patients), the incidence of in-hospital cardiac events was 47.6% (p < 0.0001), significantly higher than that in all patients. TnT-positive patients with CRP levels of 0.5 mg/dl or higher (8% of all patients) had a markedly higher incidence of in-hospital cardiac events of 56.7% (p = 0.001) and long-term cardiac events of 46.7% (p = 0.01). CONCLUSIONS: CRP levels were useful in prediction of the long-term prognosis. TnT levels were useful in prediction of in-hospital prognosis. The present study suggested the possibility that the combined use of these biological markers could predict the prognosis of patients with unstable angina at early stage and more accurately.
