Quantification of myocardial flow reserve using a gamma camera with solid-state cadmium-zinc-telluride detectors: Relation to angiographic coronary artery disease.

Background: Previous studies have suggested using gamma cameras with cadmium-zinc-telluride (CZT) detectors to quantify myocardial blood flow (MBF) and flow reserve (MFR). In this study, we aimed to evaluate the feasibility and accuracy of MFR quantification using a CZT camera compared to coronary angiography.

Methods: Forty-one participants referred for coronary angiography underwent a rest/stress one-day myocardial perfusion imaging protocol using a CZT gamma camera.

[Gender influence on the immediate and medium-term progression after primary percutaneous coronary intervention and analysis of independent risk factors for death or events].

Objective: Determine gender-related differences and risk factors for death and events, both in-hospital and at six-month evolution, of patients admitted within the first twelve hours of ST-segment elevation acute myocardial infarction and who underwent primary percutaneous coronary intervention.

Methods: Between July 1998 and December 2000, 199 consecutive patients were enrolled in the study, with elevation myocardial infarction and without cardiogenic shock, outcome, in-hospital and six-month progression were studied.

Results: Clinical characteristics were similar in both groups, except that women were older than men (67.
