Review of acute coronary syndrome diagnosis and management

Area of Science:

• Cardiology
• Internal Medicine

Background:

• Acute coronary syndrome (ACS) encompasses conditions like unstable angina and myocardial infarction (STEMI/NSTEMI) due to reduced blood flow to the heart.
• Accurate diagnosis is critical for timely intervention and improved patient outcomes.

Purpose of the Study:

• To provide primary care physicians with a concise review of ACS pathophysiology, clinical evaluation, and management.
• To highlight evolving treatment strategies based on recent clinical evidence and technological advancements.

Main Methods:

• Review of patient history, physical examination, electrocardiogram, radiographic studies, and cardiac biomarkers for diagnosis.
• Stratification of patients into low-, intermediate-, and high-risk categories for tailored management.
• Discussion of diagnostic tools including stress testing, CT angiography, and left heart catheterization.
• Overview of treatment modalities such as percutaneous coronary intervention and thrombolysis.

Main Results:

• Management approaches differ based on patient risk stratification.
• Low- and intermediate-risk patients are often evaluated in chest pain centers or emergency departments.
• High-risk patients typically undergo an early invasive strategy with left heart catheterization and revascularization.
• STEMI patients increasingly receive primary percutaneous coronary intervention, with thrombolysis used when facilities are limited.

Conclusions:

• The management of ACS is dynamic, influenced by new research and technology.
• Primary care physicians require updated knowledge on ACS evaluation and treatment.
• Evidence-based strategies are crucial for optimizing patient care in acute coronary syndromes.
