Randomized Controlled Trial Multicenter Study Observational StudyCulprit vessel versus multivessel intervention at the time of primary percutaneous coronary intervention in patients with ST-segment-elevation myocardial infarction and multivessel disease: real-world analysis of 3984 patients in London.
It is estimated that up to two thirds of patients presenting with ST-segment-elevation myocardial infarction have multivessel disease. The optimal strategy for treating nonculprit disease is currently under debate. This study provides a real-world analysis comparing a strategy of culprit-vessel intervention (CVI) versus multivessel intervention at the time of primary percutaneous coronary intervention in patients with ST-segment-elevation myocardial infarction. ⋯ In this observational analysis of patients with ST-segment-elevation myocardial infarction undergoing primary percutaneous coronary intervention, CVI was associated with increased survival at 1 year. Acknowledging the limitations with observational analyses, our findings support current recommended practice guidelines.

Randomized Controlled Trial Multicenter StudyHealth-related quality of life in patients with atrial fibrillation treated with rhythm control versus rate control: insights from a prospective international registry (Registry on Cardiac Rhythm Disorders Assessing the Control of Atrial Fibrillation: RECORD-AF).
Improving health-related quality of life (HRQoL) is an important treatment goal in the management of patients with atrial fibrillation (AF). Uncertainty exists as to whether patients' HRQoL differ when treated with medical rhythm control or rate control. We compared HRQoL between patients treated with rhythm control or rate control in a large observational registry of patients with recent-onset AF. ⋯ In this observational cohort of recent-onset AF patients, treatment with medical rhythm- or rate control over 1 year was associated with an improvement in HRQoL. The magnitude of HRQoL improvement was minimally higher in patients treated with rhythm control than rate control. However, the overall degree of improvement was not large, and its clinical significance was uncertain.
