Myocardial revascularization.

Comparison between Revascularization and Optimal Medical Therapy in Patients with Stable Angina Pectoris

Background and Purpose: Regarding usefulness of revascularization versus optimal medical therapy in patients with stable angina pectoris, data are challenging. The aim of this 12-month follow-up study was to compare the survival benefit associated with revascularization versus optimal medical therapy on the patients with stable angina pectoris. Materials and Methods: A prospective clinical s...

The value of myocardial perfusion imaging with Tc-99m MIBI for the prediction of perfusion improvement after percutaneous transluminal coronary angioplasty

  Introduction: Percutaneous transluminal coronary angioplasty (PTCA) is an effective method for revascularizing of stenotic coronary vessels. Lack of response to this treatment, either in symptomatic or asymptomatic patients, is usually due to incomplete revascularization, restenosis, and/or irreversibility of myocardial perfusion. Introduction of a noninvasive metho...

Risk factors for acute myocardial infarction during the postoperative period of myocardial revascularization.

OBJECTIVE To identify risk factors for acute myocardial infarction during the postoperative period after myocardial revascularization. METHODS This was a case-control study paired for sex, age, number, type of graft used, coronary endarterectomy, type of myocardial protection, and use of extracorporeal circulation. We assessed 178 patients (89 patients in each group) undergoing myocardial rev...

[Comparative study between the therapeutic effects of surgical myocardial revascularization and coronary angioplasty in equivalent ischemic situations: analysis through myocardial scintigraphy with 99mTc-Sestamibi].

OBJECTIVE To assess the myocardial ischemic load to previous and after myocardial revascularization. METHODS Ninety-six randomized patients, carriers of multivessel coronary artery disease, stable angina, preserved left ventricular function, and exercise-induced myocardial ischemia treated with revascularization (SMR) or coronary angioplasty (TCA). Myocardial scintigraphy with 99mTc-Sestamibi...

On-Pump versus Off-pump Myocardial Revascularization in Patients with Renal Insufficiency: Early and Mid-term Results

BACKGROUND Myocardial revascularization in patients with renal insufficiency is challenging to the cardiac surgeon, irrespective of utilizing extracorporeal circulation. This study aimed to compare the number of bypass grafts and the mid-term results and to evaluate independent survival predictors in patients with renal insufficiency undergoing on-pump or off-pump myocardial revascularization. ...
