Comparison of Triflusal with Aspirin in the Secondary Prevention of Atherothrombotic Events; Α Randomised Clinical Trial.

BACKGROUND: Triflusal has demonstrated an efficacy similar to aspirin in the prevention of vascular events in patients with acute myocardial infarction (ΜΙ) and ischaemic stroke but with less bleeding events. OBJECTIVE: We performed a randomised, multicentre, phase 4 clinical trial to compare the clinical efficacy and safety of triflusal versus aspirin, administered for 12 months in patients eligible to receive a cyclooxygenase-1 (COX-1) inhibitor. METHODS: Patients with stable coronary artery disease or with a history of non-cardioembolic ischaemic stroke were randomly assigned to receive either triflusal 300 mg twice or 600 mg once daily or aspirin 100 mg once daily for 12 months. The primary efficacy endpoint was the composite of: (a) ΜΙ, (b) stroke (ischaemic or haemorrhagic), or, (c) death from vascular causes for the entire follow-up period. The primary safety endpoints were the rate of bleeding events as defined by Bleeding Academic Research Consortium (BARC) criteria. RESULTS: At 12-month follow-up, an equivalent result was revealed between the triflusal (n=559) and aspirin (n=560) in primary efficacy endpoint. Specifically, the combined efficacy outcome rate (i.e. MI, stroke or death from vascular causes) difference was equal to -1.3% (95% confidence interval -1.1 to 3.5) and lied within the a-priori defined equivalence interval (p<0.001). Regarding the primary safety endpoints, patients on triflusal treatment were 50% less likely to develop bleeding events according to the BARC criteria, and especially any clinically overt sign of haemorrhage that requires diagnostic studies, hospitalisation or special treatment (BARC type 2). CONCLUSION: The efficacy of triflusal in the secondary prevention of vascular events is similar to aspirin when administered for 12 months. Importantly, triflusal significantly reduced the incidence of ΜΙ and showed a better safety profile compared with aspirin.

Continuous 12-lead electrocardiographic ST monitoring adds prognostic information to the thrombolysis in myocardial infarction risk score in patients with non-ST-elevation acute coronary syndromes.

BACKGROUND: Continuous 12-lead electrocardiographic (ECG) ST monitoring and the Thrombolysis In Myocardial Infarction Risk Score (TIMI-RS), both have been shown to be useful for early risk stratification in patients with non-ST elevation acute coronary syndromes (NSTACS). HYPOTHESIS: Transient ST ischemic events, detected by continuous 12-lead ECG ST monitoring, early in the course of NSTACS, may add prognostic information to the TIMI-RS. METHODS: In all, 567 consecutive patients with a NSTACS underwent 24-h continuous 12-lead ECG ST monitoring. An ST ischemic event was defined as a transient ST shift in any lead of > or = 0.10 mV compared with the reference ECG, lasting for > or = 1 min. RESULTS: The incidence of the composite of death, nonfatal myocardial infarction (or reinfarction) and recurrent ischemia by Day 14 was 22.2%. By Day 30, the incidence of the composite of death and nonfatal myocardial infarction (or reinfarction) was 14.7%. There was a significantly increased risk of 14-day (p value for trend < 0.001) or 30-day (p value for trend <0.001) composite endpoint with increasing of TIMI-RS. Moreover, the occurrence of > or = 1 ST shifts during ST monitoring was associated with a significantly increased risk of 14- (p value < 0.001) or 30-day (p value < 0.001) composite endpoint, and this was true throughout the groups of TIMI-RS. CONCLUSIONS: The present study suggests that continuous 12-lead ECG ST monitoring, early in the course of NSTACS, may serve as an affordable tool to add prognostic information to the TIMI-RS.
