Why the study?
Does preprocedural angina frequency predict quality-of-life improvement after percutaneous coronary intervention?
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.
Emphasizes symptom evaluation prior to PCI; leaves open randomized confirmation of QoL gains by angina frequency.
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.
