Early Invasive Versus Initially Conservative Strategy in Elderly Patients Older Than 75 Years with Non-ST-Elevation...

Area of Science:

• Cardiology
• Geriatric Medicine
• Interventional Cardiology

Background:

• Invasive angiography is often withheld in elderly patients due to fear of complications and unclear benefits.
• Non-ST-elevation acute coronary syndrome (NSTE-ACS) management in older adults presents unique challenges.

Purpose of the Study:

• To evaluate the efficacy and safety of an early invasive strategy versus a conservative strategy for elderly patients (older than 75 years) with NSTE-ACS.
• To synthesize evidence from existing studies to inform clinical decision-making.

Main Methods:

• A systematic search of PubMed and Embase databases was conducted up to February 2016.
• Included studies enrolled patients over 75 years with NSTE-ACS, comparing invasive versus conservative management.
• Data from four randomized controlled trials (RCTs) and nine observational studies involving 832,007 patients were analyzed.

Main Results:

• The early invasive approach significantly reduced the risk of death at 6 months to 5 years (RR 0.65, p<0.001), particularly in observational studies.
• A trend toward reduced mortality was observed in RCTs (RR 0.82, p=0.119).
• Patients undergoing the invasive strategy had a higher risk of any in-hospital bleeding (RR 2.51, p<0.001), but no significant difference in major in-hospital bleeding was found.

Conclusions:

• Elderly patients with NSTE-ACS may benefit from an early invasive strategy, showing reduced mortality.
• The invasive approach is associated with an increased risk of any bleeding complications.
• Further high-quality RCTs are required to definitively assess the benefits and risks of early invasive strategies in the elderly NSTE-ACS population.
