Elderly patients represent 72.6 percent of patients who receive the percutaneous coronary intervention treatment for unprotected left main coronary artery stenosis (ULMCA) stenosis.
Trend data, however, indicate the use of this procedure is slowly increasing, and is being used more often for lower-urgency procedures.
Poor health outcomes in elderly ULMCA patients are common and are likely influenced by both patient and procedural factors, including the type of stent used.
The study showed 40% of elderly patients die within the first 3 years of followup after the procedure.
Researchers concluded that clinical trials are needed to examine the safety and effectiveness of angioplasty in patients with ULMCA disease, with attention to best practices and the generalizability of trial populations.
