Accuracy of Myocardial Biomarkers in the Diagnosis of Myocardial Infarction After Revascularization as Assessed by Cardiac Resonance: The Medicine, Angioplasty, Surgery Study V (MASS-V) Trial.

Background: The lack of a correlation between myocardial necrosis biomarkers and electrocardiographic abnormalities after revascularization procedures has resulted in a change in the myocardial infarction (MI) definition.

Methods: Patients with stable multivessel disease who underwent percutaneous or surgical revascularization were included. Electrocardiograms and concentrations of high-sensitive cardiac troponin I (cTnI) and creatine kinase (CK)-MB were assessed before and after procedures.

Mortality and embolic potential of cardiac tumors.

Background: Cardiac tumors are rare, mostly benign with high embolic potential.

Objectives: To correlate the histological type of cardiac masses with their embolic potential, implantation site and long term follow up in patients undergoing surgery.

Methods: Between January 1986 and December 2011, we retrospectively analyzed 185 consecutive patients who underwent excision of intracardiac mass (119 females, mean age 48±20 years).

Effects of acute hormone therapy on recurrent ischemia in postmenopausal women with unstable angina.

Objectives: We tested whether acute hormone therapy reduces ambulatory electrocardiographic ischemia in postmenopausal (PMP) women with unstable angina (UA).

Background: Endothelial dysfunction contributes to the pathophysiology of UA. Acute estrogen administration improves endothelial function in PMP women with coronary artery disease and increases coronary artery blood flow.
