[The progress of autonomic parameters in patients after myocardial infarction with ST elevation]

Area of Science:

• Cardiology
• Autonomic Neuroscience
• Internal Medicine

Context:

• ST-elevation myocardial infarction (STEMI) poses risks including autonomic dysfunction, decreased baroreflex sensitivity, and altered heart rate variability.
• Increased sympathetic activity or decreased parasympathetic activity can exacerbate these post-STEMI complications.
• Effective management strategies are crucial for mitigating long-term cardiovascular risks in STEMI patients.

Purpose:

• To evaluate the one-year follow-up of autonomic function and cardiac mortality in STEMI patients treated with direct angioplasty and optimal pharmacotherapy.
• To assess the impact of modern cardiovascular interventions on autonomic nervous system parameters post-STEMI.
• To identify subgroups of STEMI patients at higher risk for persistent autonomic dysfunction and adverse cardiac remodeling.

Summary:

• One-year follow-up revealed no significant changes in autonomic dysfunction parameters (baroreflex sensitivity, heart rate variability, blood pressure variability) in STEMI patients.
• Direct angioplasty and optimal pharmacotherapy were associated with very low cardiac mortality.
• Autonomic dysfunction and negative left ventricular remodeling were observed only in a small, difficult-to-stratify subgroup of STEMI patients.

Impact:

• Current interventional and pharmacological treatments for STEMI appear effective in stabilizing autonomic function and reducing cardiac mortality.
• The findings suggest that most STEMI patients benefit significantly from contemporary management, with autonomic stability achieved.
• Further research is needed for precise risk stratification of the small patient cohort experiencing persistent autonomic dysfunction and adverse remodeling post-STEMI.
