Information provided by (Responsible Party):
Niguarda Hospital
  Purpose

A randomized study comparing an early aggressive with an initially conservative strategy in patients >74 y.o. with non-ST-elevation acute coronary syndrome.

This study had generated a secondary one:

"Causes of death in elderly patients with Non-ST-Elevation Acute Coronary Syndrome; predictors of in-hospital and follow-up death"


Condition Intervention
Acute Coronary Syndrome Other: systematic coronary intervention Other: coronary intervention only for cases refractory to medical therapy

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Italian Elderly ACS Study

Further study details as provided by Niguarda Hospital:

Primary Outcome Measures:
  • The composite of all-cause mortality, myocardial (re)infarction, disabling stroke and re-hospitalization for cardiovascular causes or severe bleeding within 1 yr. [ Time Frame: 1 year ]

Secondary Outcome Measures:
  • CV mortality at 1 yr; All-causes mortality, myocardial re/infarction 1 yr; Composite of death, myocardial re/infarction, disabling stroke, rehospitalization due to cardiovascular or clinically bleeding causes at 1 yr; Major bleeding, stroke at 1 yr [ Time Frame: 1 year ]

Enrollment: 313
Study Start Date: October 2007
Study Completion Date: June 2011
Primary Completion Date: June 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
Coronary angiography within 72h and revascularization as clinical indicated
Other: systematic coronary intervention
Coronary angiography within 72 hrs
No Intervention: 2
Initially conservative treatment with coronary angiography only for recurrent ischemia
Other: coronary intervention only for cases refractory to medical therapy
Initially conservative treatment with coronary angiography only for recurrent ischemia

Detailed Description:

Patients >74 y.o. with non-ST-elevation acute coronary syndrome will be randomised to an early aggressive (coronary angiography within 72 hours followed, when indicated, by revascularization) or an initially conservative strategy (medical therapy, and coronary angiography only for refractory ischemia).

As reported in Amendment 1, the trial was stopped in May 2010 after the enrolment of 313 patients, which was the minimum sample size calculated in order to achieve a 80% power of detecting a difference in the primary-endpoint rate from 40% in the conservative arm to 25% in the invasive arm, based upon the log-rank test for survival curves (1-beta 0.80; 2-tailed alpha 0.05)
