Management of restenosis after coronary intervention
American Heart Journal, 1996Coronary restenosis has proven to be the "Achilles heel" of percutaneous coronary interventions, frequently leading to repeated procedures. The pathogenesis of restenosis can be divided into four phases: early elasic recoil (hours to days), mural thrombus formation (hours to days), neointimal proliferation and extracellular matrix formation (weeks ...

Restenosis in intervened coronaries with hyperhomocysteinemia (RICH)
American Heart Journal, 2003Controversy exists regarding the contribution made by elevated serum homocysteine evels in raising the risk of restenosis after percutaneous coronary interventions. The objective of this study was to determine whether elevated homocysteine evels increase the risk of restenosis.Two hundred and two consecutive patients undergoing percutaneous coronary ...

Consequences of restenosis after coronary angioplasty
International Journal of Cardiology, 1991The consequences of restenosis after angioplasty were evaluated in 466 patients who had coronary angiography 3 to 12 months after successful coronary angioplasty and were followed long term. The 236 subjects with restenosis resembled the 230 without restenosis with respect to age, sex, presence of multivessel disease, mean ejection fraction, prior ...

Restenosis After Coronary Balloon Angioplasty
Annual Review of Medicine, 1991A recurrence of stenosis (restenosis) following successful coronary angioplasty continues to be a frequent problem limiting the long-term efficacy of the procedure. An overexuberant reparative response to the arterial injury induced by balloon dilatation leads to intimal hyperplasia, the major mechanism responsible for restenosis. Although none has yet

Coronary restenosis: a review of mechanisms and management
The American Journal of Medicine, 2003Percutaneous coronary interventions represent an attractive alternative to surgical revascularization; nevertheless, these techniques continue to be characterized by their propensity to elicit restenosis. Despite an exhaustive search for an effective pharmacotherapy to treat or prevent restenosis, hundreds of clinical trials have failed to identify an ...

Treatment options for coronary stent restenosis
Comprehensive Therapy, 1999Treatment of in-stent restenosis with balloon angioplasty alone is adequate for focal lesions but is associated with a 50% recurrence rate for diffuse lesions. For diffuse in-stent restenosis, debulking with atherectomy or laser can significantly reduce the recurrence rate.

Precision management of coronary in-stent restenosis
Trends in Cardiovascular MedicineThe advent of percutaneous coronary intervention (PCI) and intracoronary stent development marked a pivotal milestone in the management of acute coronary syndromes, significantly reducing morbidity and mortality worldwide. However, despite ongoing advancements in stent technology, treatment modalities, and diagnostic tools, in-stent restenosis (ISR ...

The role of proto-oncogenes in coronary restenosis
Progress in Cardiovascular Diseases, 1997Arterial injury results in exposure of medial smooth muscle cells and adventitial fibroblasts to multiple growth factors that bind to specific cell surface receptors. These in turn activate second messengers and induce expression of immediate-early genes within minutes to hours after ligand binding to the receptor.
