- Understanding the natural history and survival patterns is crucial for effective treatment.
- Surgical interventions have evolved significantly over time.
Purpose of the Study:
- To review the natural history and survival of coronary atherosclerosis.
- To examine the evolution of surgical treatments for ischemic heart disease.
- To compare survival rates between medical and surgical management.
Main Methods:
- Review of historical data on coronary atherosclerosis.
- Analysis of surgical techniques, including venous autografts and internal mammary artery grafts.
- Comparative survival analysis of medical versus surgical treatments.
- Evaluation of factors influencing revascularization selection and longevity.
Main Results:

- Improved surgical techniques and patient selection have led to reduced operative mortality and morbidity.
- Long-term survival rates have improved due to these advancements.
Conclusions:
- Modern surgical approaches offer improved long-term survival for patients with coronary atherosclerosis.
- Refined patient selection and technical proficiency are key to successful revascularization outcomes.
- Continuous improvement in surgical care enhances the prognosis for ischemic heart disease.
Abstract:
Coronary atherosclerosis is discussed from the standpoint of natural history and survival. The operative treatment for ischemic heart disease is reviewed beginning with the advent of the venous autograft to the most recent advance, the internal mammary artery graft. Comparative survival between medical and surgical modes of treatment are described as well as factors in the revascularization selection process that directly influence longevity. During the last 6 years, experience in selection and a steady improvement in technical proficiency have brought about a decline in operative mortality and morbidity, thus yielding further improvement in postoperative long-term survival.
