The smoker's paradox after successful fibrinolysis: reduced risk of reocclusion but no improved long-term cardiac outcome

Contains fulltext : 81178.pdf (publisher's version ) (Closed access)BACKGROUND: In smokers treated with fibrinolysis for ST-elevation myocardial infarction (STEMI) a paradoxical beneficial short-term outcome has been reported. This was attributed to favorable clinical and angiographic baseline variables and a better response to fibrinolysis. During follow-up infarct artery reocclusion is an important prognosticator. We studied the effects of smoking on reocclusion and long-term cardiac outcome after successful fibrinolysis. METHODS: In the Antithrombotics in the Prevention of Reocclusion In COronary Thrombolysis trials (APRICOT-1 and -2) 499 STEMI patients with an open infarct artery <48 h after fibrinolysis received randomized antithrombotic treatment until 3-month follow-up angiography. Five-year clinical follow-up was complete. RESULTS: Current smokers (317 patients, 64%) had favorable clinical (age 54 vs. 60 years, P < 0.01) and angiographic (single vessel disease 61% vs. 49%, P = 0.02) baseline characteristics. Reocclusion rates were 21% (67/317) in smokers versus 32% (59/182) in non-smokers (P < 0.01). Five-year infarct-free cardiac survival did not differ: 82% vs. 85%. Reocclusion (HR 2.41, 95%CI 1.05-5.56, P = 0.04) independently predicted cardiac mortality. Smoking was independently associated with a reduced risk of reocclusion (OR 0.58, 95%CI 0.37-0.91, P = 0.02), but not with improved 5-year cardiac outcome (HR 1.34, 95%CI 0.79-2.25, P = ns). CONCLUSIONS: After successful fibrinolysis, smoking is independently associated with a more than 40% reduced risk of reocclusion, which is an independent predictor of adverse outcome. However, even with more favorable baseline characteristics smokers did not have improved 5-year cardiac outcome in this low-risk population

Acute myocardial infarction due to coronary artery embolism in a patient with atrial fibrillation.

A 66-year-old female was referred for primary coronary intervention because of acute inferior STelevation myocardial infarction. Electrocardiography also showed atrial fibrillation. Coronary angiography showed a distal occlusion of the right coronary artery. Two different wires did not pass the occlusion, but dislodged the apparent thrombus more distally. No abnormalities were seen in the course of the recanalised part of the vessel. The sequential angiographic images together with the presence of atrial fibrillation are highly suggestive of coronary embolism as the cause of the myocardial infarction. Anticoagulation and rate control strategy was initiated. The patient was discharged in good condition. (Neth Heart J 2009;17:297-9.)

[Antithrombotic therapy during percutaneous coronary interventions]

Antithrombotic therapy is essential during percutaneous coronary interventions for the prevention of peri-procedural death and myocardial infarction. The most commonly used agents are aspirin, clopidogrel and heparin in patients treated by percutaneous angioplasty or receiving an arterial stent. Glycoprotein IIb/IIIa receptor antagonists such as abciximab are indicated during percutaneous interventions in high-risk-patients as well as, in principle, in all patients with an acute coronary syndrome with ST-segment elevation undergoing primary percutaneous angioplasty. In patients with so-called drug-eluting stents, clopidogrel should be continued for several months longer than the usual 30 days

[Reperfusion therapy for patients with an acute myocardial infarct with ST-segment elevation: fibrinolysis versus transport to a cardiac center for primary angioplasty]

Although fibrinolytic therapy for acute myocardial infarction is widely used and can be administered prior to hospitalisation, it is only successful in restoring full early coronary patency in about 60% of patients and has a 0.5% to 1% risk of severe side effects. Primary percutaneous coronary angioplasty carried out as an alternative to fibrinolysis avoids the risk of fibrinolytic therapy and restores patency in nearly 90% of cases. Data from randomised trials of primary angioplasty versus fibrinolytic therapy in acute myocardial infarction reveal that angioplasty results in a significant reduction in mortality. Furthermore, primary angioplasty can be improved by means of a new pre-angioplasty drug therapy (so-called facilitated primary angioplasty). Transport to a cardiac centre for primary angioplasty (of which there are 14 in the Netherlands) is feasible and safe. Although the time to treatment is delayed by a further 90 minutes, it tends to save lives and prevent strokes and it also significantly reduces the incidence of reinfarction. Interestingly, the time gained to treatment with prehospital fibrinolytic therapy compared to in-hospital therapy gave an outcome similar to that found upon comparing transport and primary angioplasty. Rescue procedures (angioplasty) within 24 hours are necessary in about 30% of patients who are initially treated with lytic therapy. These results support prehospital triage for fibrinolysis or transport to a cardiac centre, where early angioplasty can be performed if clinically indicated. A trial to determine the policy of choice is at present being conducted in the Netherlands
