Coronary revascularization (surgical or percutaneous) decreases mortality after the first year in diabetic subjects...

Area of Science:

• Cardiology
• Interventional Cardiology
• Diabetology

Background:

• The impact of revascularization on mortality in diabetic patients remains unclear.
• Comparing surgical, percutaneous, and medical treatments is crucial for cardiovascular disease management.

Purpose of the Study:

• To investigate the long-term effects of coronary artery revascularization versus medical treatment on mortality in diabetic patients.

Main Methods:

• Analysis of the MASS II trial data, including 190 diabetic patients with stable multivessel coronary disease.
• Random assignment to medical treatment, angioplasty, or surgery.
• 5-year mortality follow-up, with separate analyses for the first year and subsequent years (2-5).

Main Results:

• No significant difference in 5-year cumulative mortality or first-year mortality among treatment groups for diabetic or non-diabetic patients.
• Diabetic patients undergoing angioplasty or surgery showed significantly lower mortality between years 2 and 5 compared to medical treatment (P=0.039).
• Non-diabetic patients showed no significant mortality differences between treatment groups during years 2-5.

Conclusions:

• Coronary revascularization (surgical or percutaneous) offers significant long-term survival benefits for diabetic patients compared to medical management alone.
• Mortality rates are similar for non-diabetic patients across medical, surgical, and angioplasty treatments.
• Revascularization strategies should be considered for diabetic patients with multivessel coronary disease to improve long-term outcomes.
