Does preprocedural angina frequency predict quality-of-life improvement after percutaneous coronary intervention?
Preprocedural angina frequency is the primary driver of quality-of-life improvement after PCI, highlighting the need for careful consideration before intervening in asymptomatic patients.
Preprocedural angina frequency is the most important prognostic indicator of quality-of-life improvement after PCI. Although substantial quality-of-life benefits are attained in most patients with preprocedural angina, more careful consideration of the potential benefits and risks of the procedure are needed in asymptomatic patients.
Spertus et al. (2004) studied this question.
