Conservative strategy for treatment of stable coronary artery disease

Area of Science:

• Cardiology
• Clinical Medicine

Background:

• Prognosis in coronary artery disease (CAD) is highly variable.
• Ventricular function is a key determinant of patient outcomes.
• Current literature lacks clarity on optimal treatment strategies for CAD.

Purpose of the Study:

• To compare the efficacy of invasive myocardial revascularization versus conservative optimized medical therapy.
• To investigate treatment strategy effectiveness across different CAD subgroups.

Main Methods:

• Comparative analysis of treatment strategies.
• Evaluation of major adverse cardiac events (MACE) including death and myocardial infarction.
• Subgroup analysis based on coronary artery anatomy.

Main Results:

• No significant difference in major outcomes (death, myocardial infarction) between invasive and conservative strategies was found.
• This similarity in prognosis extended to most patient subgroups.
• Left main coronary artery disease was an exception where prognosis may differ.

Conclusions:

• For most patients with coronary artery disease, an invasive revascularization strategy does not appear superior to optimized medical therapy regarding major adverse cardiac events.
• Treatment decisions should consider individual patient factors and specific coronary anatomy, such as left main disease.
