PURPOSE There is still debate about the timing of revascularization in patients with acute non-ST-segment elevation myocardial infarction (NSTEMI). We analyzed the long-term clinical outcomes of the timing of revascularization in patients with acute NSTEMI obtained from the Korea Acute Myocardial Infarction Registry (KAMIR). MATERIALS AND METHODS 2,845 patients with acute NSTEMI (65.6 +/- 12....
We have previously reported that angina pectoris persists in patients with coronary microvascular spasm (MVS) even on calcium channel blockers. Because measurement of myocardial lactate production in the coronary sinus is necessary to diagnose MVS, a more feasible diagnostic method needs to be developed. In this study, we examined the diagnostic significance of Thrombolysis in Myocardial Infarc...
A ngiography has been used to monitor the effects of thrombolytic therapy on coronary artery anatomy and flow during the early hours of acute of myocardial infarction since the early 1980s.1-3 Several early investigators noted a spectrum of responses of initially occluded coronary arteries to thrombolytic therapy using angiographic assessment.4,5 The Thrombolysis in Myocardial Infarction (TIMI)...
OBJECTIVES The aim of the study was to assess the angiographic and clinical benefits of the calcium T-channel blocker, mibefradil, in the coronary slow flow phenomenon (CSFP). BACKGROUND The CSFP is characterized by delayed vessel opacification on angiography (Thrombolysis In Myocardial Infarction [TIMI]-2 flow) in the absence of obstructive epicardial coronary disease and is often associated...
BACKGROUND When evaluating new reperfusion regimens for ST elevation MI, it is important to adjust for factors that influence the likelihood of achieving normal epicardial flow and complete ST resolution. METHODS AND RESULTS A total of 610 patients from TIMI 14 contributed to the angiographic analyses. The electrocardiographic analyses were based on 544 patients from TIMI 14 and 763 patients ...
INTRODUCTION Patients with ST elevation acute myocardial infarction (STEMI) comprise a heterogeneous population with respect to the risk for adverse events. Primary percutaneous coronary intervention (PCI) has shown to be better, mainly in high-risk patients. OBJECTIVE The purpose of this study was to determine if the Thrombolysis in Myocardial Infarction (TIMI) risk score for STEMI applied t...
BACKGROUND Although the TIMI score is the one most frequently used in acute coronary syndromes (ACS) without ST-segment elevation, the GRACE score has potential prognostic superiority, as it was created based on an observational registry, part of the variables is treated in a semi-quantitative form and renal function is taken into account in its calculation. OBJECTIVE To test the hypothesis t...
BACKGROUND Management of patients with acute non-ST segment elevation myocardial infarction (NSTEMI) depends on risk evaluation. The recommended approach involves the use of risk stratification tools such as TIMI and GRACE risk scores. However, these clinical scores do not include variables derived from coronary angiography which is currently performed in most patients. AIM To evaluate the pr...
The Western Washington Intracoronary Streptokinase randomized trial1 first demonstrated that intracoronary thrombolytic therapy improved survival for patients presenting within 12 hours of symptom onset of acute myocardial infarction (MI). Perhaps equally important, this invasive study demonstrated that in-hospital and long-term survival was greatly improved in patients with patent infarctrelat...
Introduction: No-reflow phenomenon in coronary vessels, manifested in some patients with reperfused acute myocardial infarction (MI), is associated with poor clinical and functional outcomes. Therefore, evaluation of predisposing risk factors can be helpful in risk assessment and identification of patients at higher risk. Herein, we aimed to study the predictive factors for the development of...
