Insights
Interventional cardiology has advanced significantly since 1988, with new devices and molecular biology approaches tackling restenosis. Cardiologists now face complex choices regarding which interventional technologies to use.
Area of Science:
- Cardiology
- Interventional Cardiology
- Cardiovascular Research
Background:
- Review updates 1988 observations on percutaneous transluminal coronary angioplasty.
- Initial concerns focused on rethrombosis and restenosis, with the BARI study in planning.
- The field has evolved rapidly since 1988.
Purpose of the Study:
- To review the advancements in interventional cardiology since 1988.
- To highlight the progress in addressing restenosis.
- To discuss the evolving decision-making process for interventional technologies.
Main Methods:
- Literature review and synthesis of advancements in interventional cardiology.
- Discussion of the impact of new catheter devices.
- Examination of the role of basic science and molecular biology in cardiovascular research.
Main Results:
- Interventional cardiology now includes angioplasty, atherectomy, laser, and stents.
- Basic scientists are actively involved in solving restenosis.
- The Bypass Angioplasty Revascularization Investigation (BARI) trial is nearing completion.
Conclusions:
- The landscape of interventional cardiology has transformed with diverse technologies.
- Molecular biology approaches are crucial for addressing remaining challenges like restenosis.
- Clinicians face complex decisions regarding the selection and application of various interventional techniques.
Abstract:
This review updates and extends observations made in this journal in March 1988. The focus then was on percutaneous transluminal coronary angioplasty and the clinical results of its practical application. A concern was expressed that science lagged in solving the major problems of rethrombosis and restenosis. The NHLBI Bypass Angioplasty Revascularization Investigation (BARI) study was still in the planning phase. In 1991, the scene has changed. Interventional cardiology now embraces a multitude of different catheter devices--angioplasty, atherectomy, laser, stents. Basic scientists are increasingly involved in addressing the restenosis issue. Our national heart meetings are increasingly oriented towards molecular biology approaches to solving the remaining problems. The BARI trial has nearly completed patient entry, and we eagerly await its results. The cardiologist and surgeon are faced with increasingly complex decisions with respect to interventional technologies, involving not only whether to use them, but which ones.
