Transforming post-STEMI care: The IMPACS study design and baseline patient profile

Area of Science:

• Cardiology
• Public Health
• Clinical Research

Background:

• Long-term outcomes after ST-segment elevation myocardial infarction (STEMI) are suboptimal due to gaps in secondary prevention.
• The IMPACS study was designed to address these gaps with a structured outpatient management strategy.

Purpose of the Study:

• To evaluate a standardized, intensified outpatient disease-management program for STEMI patients during the first year post-discharge.
• To compare the effectiveness of this intensified program against standard care.

Main Methods:

• A national, prospective, multicentre study comparing an intensified outpatient program with standard care.
• 1031 STEMI patients were enrolled, receiving four structured outpatient visits focusing on clinical assessment, pharmacotherapy, and risk-factor management.
• The primary endpoint is a composite of all-cause mortality and cardiovascular hospitalizations, compared to matched administrative data controls.

Main Results:

• The study included 1031 patients (mean age 62 years, 75% male) with high prevalence of cardiovascular risk factors (hypertension 73%, high LDL-C 75%, diabetes 23%, smoking 49%).
• Guideline-directed medical therapy at discharge was high (dual antiplatelet therapy 95%, statins 99%).
• Primary percutaneous coronary intervention (PCI) was performed in 96% of patients.

Conclusions:

• The IMPACS study introduces a novel approach to post-acute coronary syndrome (ACS) care.
• Baseline findings highlight the need for intensified secondary prevention in STEMI patients due to a high burden of cardiovascular risk factors.
• Further follow-up is required to determine the long-term impact of this strategy on clinical outcomes.
