revascularization are needed. We also agree with Conti’s opinion that, unless ischemia is present, collaterals do not appear angiographically; if the collateral provides excellent blood flow to ischemic myocardium, the collaterals will remain (2). Werner et al. (3) reported that even collaterals that appear well developed on angiography are not able to fully replace anterograde blood flow; ther...

BACKGROUND Patients with non-ST-elevation acute coronary syndrome complicated by congestive heart failure (CHF) have a poor prognosis. The aims of this study were to describe the use of revascularization in non-ST-elevation acute coronary syndrome and CHF and to analyze its impact on survival. METHODS AND RESULTS In the Global Registry of Acute Coronary Events, 29 844 patients with non-ST-ele...

BACKGROUND AND PURPOSE Higher rates of target vessel patency at 24 hours were noted in the thrombectomy group compared with control group in recent randomized trials. As a prespecified secondary end point, we aimed to assess 24-hour revascularization rates by treatment groups and occlusion site as they related to clinical outcome and 24-hour infarct volume in REVASCAT (Randomized Trial of Revas...

Clinical experience with transmyocardial laser revascularization has increased significantly over the last few years. Since several transmyocardial laser revascularization studies reported an apparent effect on the relief of angina and the FDA approved reimbursement of transmyocardial laser revascularization procedures in the USA, thousands of patients have been treated worldwide with different...

OBJECTIVES To determine the relative degree of revascularization obtained with bypass surgery versus angioplasty in a randomized trial of patients with multivessel disease requiring revascularization (Bypass Angioplasty Revascularization Investigation [BARI]), one-year catheterization was performed in 15% of patients. BACKGROUND Complete revascularization has been correlated with improved out...

this is a case of severely stunned left ventricle which occurred after a non-st elevation myocardial infarction in a 76-year-old woman who was a known case of three-vessel disease. her symptoms and cardiac function responded well to revascularization.

BACKGROUND Although practice guidelines recommend coronary revascularization for patients with heart failure, the evidence to support this recommendation is weak. The objective of our study was to determine the association of coronary revascularization with survival in patients who have had heart failure. METHODS Data were obtained from the Alberta Provincial Project for Outcomes Assessment i...

BACKGROUND Many ST-segment elevation myocardial infarction (STEMI) patients have multivessel disease. There is still controversy in treatment strategy in STEMI patients with multivessel disease. We compared clinical outcomes of multivessel revascularization with infarct- related artery (IRA) revascularization in STEMI patients. METHODS The 1,644 STEMI patients with multivessel disease (1,106 ...

We aim to evaluate the potential benefit and risk of addition of vorapaxar to standard medical therapy in patients who underwent coronary revascularization with either percutaneous coronary revascularization or coronary artery bypass graft surgery. We searched PubMed, EMBASE, the Cochrane Central Register of Controlled trials, and the clinical trial registry maintained at clinicaltrials.gov for...

introduction: in cases with potential diagnosis of ischemic chest pain, screening high risk patients for adverse outcomes would be very helpful. the present study was designed aiming to determine the diagnostic accuracy of thrombolysis in myocardial infarction (timi) score in patients with potential diagnosis of ischemic chest pain. method: this diagnostic accuracy study was designed to evaluat...
