Angina pectoris in patients with a history of myocardial infarction

Area of Science:

• Cardiology
• Internal Medicine

Background:

• Patients with angina pectoris and a history of myocardial infarction (MI) often present with coronary artery disease (CAD), impaired left ventricular function, or multivessel disease.
• Angina signifies ongoing myocardial ischemia, but its prognostic significance post-MI is not fully established, unlike left ventricular function.

Purpose of the Study:

• To review the prognostic implications of angina in post-MI patients.
• To discuss the role of coronary angiography and revascularization in managing angina post-MI.
• To highlight considerations for anti-anginal therapy in this patient population.

Main Methods:

• Literature review focusing on angina pectoris, myocardial infarction, coronary artery disease, and left ventricular function.
• Analysis of prognostic factors and treatment strategies for post-MI angina.
• Discussion of diagnostic and therapeutic interventions.

Main Results:

• Left ventricular function is the primary prognostic factor in patients with a history of MI.
• Coronary angiography is crucial for identifying left main or multivessel CAD before anti-anginal therapy.
• Revascularization may benefit patients with impaired left ventricular function, but its prognostic value requires further assessment.

Conclusions:

• Anti-anginal therapy is indicated when revascularization is unsatisfactory, contraindicated, or not indicated.
• Careful consideration of potential negative inotropic or chronotropic effects of beta-blockers and calcium antagonists is necessary.
