Quality of Life in Patients with Multivessel Coronary Artery Disease: Ten-year Follow-up of a Comparison of Surgical, Angioplasty or Medical Strategies - MASS II Trial

Aims: We assessed quality of life (QoL) in patients with symptomatic multivessel coronary disease who randomly underwent surgery, angioplasty, or medical treatment. Although the clinical benefits of coronary interventions seem to be confirmed, their effects on QoL are still scarcely studied.
