Angiographic and clinical predictors of acute closure after native vessel coronary angioplasty.
Why the study?
What are the angiographic and clinical predictors of acute closure after native vessel coronary angioplasty?
Population
451 PTCA procedures selected from 4,772 procedures performed between April 1982 and March 1986.
Comparison
Clinical, angiographic, and procedural variables vs Successful PTCA attempts without acute closure
Design
Case-control

Implication
While preprocedural factors can estimate the risk of acute coronary closure after PTCA, the most powerful predictors are procedural factors assessed during the intervention itself.
Structured PICO
What are the angiographic and clinical predictors of acute closure after native vessel coronary angioplasty?
P
Population
451 PTCA procedures (140 complicated by acute closure and 311 representative successful attempts) selected from 4,772 procedures performed between April 1982 and March 1986.
I
Intervention
Clinical, angiographic, and procedural variables (including stenosis characteristics and procedural outcomes)
C
Comparator
Successful PTCA attempts without acute closure
O
Outcome
Acute coronary closure after percutaneous transluminal coronary angioplasty (PTCA)safety
While preprocedural factors can estimate the risk of acute coronary closure after PTCA, the most powerful predictors are procedural factors assessed during the intervention itself.
