DANAMI 3-PRIMULTI Substudy – Complete Revascularization Guided by FFR Improves Prognosis in STEMI Patients with Severe Nonculprit Lesions

Research Background In patients with ST-segment elevation myocardial infarction (STEMI), approximately 50% have multivessel disease (MVD), which is associated with a poor prognosis, especially when there are three-vessel lesions or chronic total occlusions. Although emergency PCI is the standard treatment for STEMI, there is still controversy regarding the management strategy for nonculprit lesions (complete revascularization … Read more

Subgroup Analysis of DANAMI-3-PRIMULTI: The Impact of Age on Prognosis After Complete Revascularization

Research Background With the increasing number of elderly patients receiving primary percutaneous coronary intervention (PPCI), the management strategies for non-culprit lesions have become controversial. Although multiple studies support that complete revascularization (treating all significant stenosed vessels) can improve prognosis, the benefits for elderly patients (≥75 years) remain unclear due to their comorbidities and shorter life … Read more

DANAMI-3-PRIMULTI Substudy—Cardiac Magnetic Resonance Confirms the Impact on Cardiac Structure and Function

Research Background Patients with ST-segment elevation myocardial infarction (STEMI) combined with multivessel disease (MVD) account for approximately 45% of all STEMI patients, and they have a poorer clinical prognosis. Previous studies (such as PRAMI, CvLPRIT) have shown that complete revascularization (treating all significantly narrowed vessels) can reduce major adverse cardiovascular events (MACE) compared to treating … Read more
