Management of Elderly Patients with Non-ST-Elevation Myocardial Infarction

Risk Stratification and Diagnosis

The American College of Cardiology/American Heart Association (ACC/AHA) guidelines indicate that elderly patients with elevated and rising cardiac troponin levels, hypertension, and transient chest pain are at high risk for adverse outcomes 1, 2
A rising troponin pattern, such as 16→50→48 ng/L, confirms acute myocardial necrosis and is a critical diagnostic feature for non-ST-elevation myocardial infarction (NSTEMI) 3, 4
The European Society of Cardiology recommends that patients with NSTEMI undergo urgent coronary angiography within 24 hours, especially if they have high-risk features such as elevated troponin levels and multiple cardiovascular risk factors 1, 2, 4

The ACC/AHA guidelines recommend initiating antiplatelet and antithrombotic therapy immediately upon diagnosis of NSTEMI, including aspirin, a P2Y12 inhibitor, and anticoagulation with unfractionated heparin or enoxaparin 1, 2
Blood pressure management is crucial, with careful control of hypertension to reduce myocardial oxygen demand, and consideration of beta-blockers unless contraindicated 1, 2
Continuous cardiac monitoring and supportive care, including supplemental oxygen and pain control with morphine, are also essential 1, 2

Any troponin elevation predicts increased mortality risk, with the degree of elevation correlating directly with adverse outcomes 1, 2, 5
Early revascularization significantly reduces death, MI, and stroke in high-risk patients, and the maximum troponin level is more predictive of mortality than initial or change in troponin 1, 2, 5
