Implication
Angioplasty may relieve symptoms in selected unstable angina cases; leaves open need for randomized confirmation of efficacy and safety.
Structured PICO
Does coronary angioplasty relieve ischemic symptoms and prevent progression to myocardial infarction in patients with unstable angina and transient marked ST-segment elevation?
P
Population
16 patients presenting with chest pain at rest associated with transient marked ST-segment elevation (≥0.5 mV) and at least one haemodynamically significant coronary artery stenosis.
I
Intervention
Coronary angioplasty (premedicated with a combination of nitroglycerin, calcium-antagonists, and beta-receptor blockers).
O
Outcome
Immediate and short-term results including initial success rate, complications, angina recurrence, and angiographic restenosis.
Coronary angioplasty is effective in relieving ischemic symptoms and preventing progression to myocardial infarction in patients with unstable angina and transient marked ST-segment elevation.
