Abstract

Angiotensin-converting enzyme inhibitors have been reported to inhibit in-stent restenosis. To assess the effect of angiotensin-converting enzyme inhibition on in-stent restenosis and its relation to apoptosis, 86 patients with chronic coronary artery disease who required stent implantation in the left anterior descending coronary artery or a major diagonal branch were studied. Patients were randomized to receive quinapril 40 mg/day orally (n = 43) or a placebo (n = 43). Drug therapy was initiated 1 week before initial stenting and continued for 6 months. Plasma levels of the apoptotic signaling molecules soluble Fas and soluble Fas ligand obtained from blood drawn from the left anterior descending coronary artery were measured just before initial stenting and 6 months later, at the time of repeat coronary angiography. In-stent restenosis was present in 9.3% of patients in the quinapril group and 25.6% of patients in the placebo group (p = 0.047). Mean late luminal loss was 0.56 +/- 0.51 mm in the quinapril group and 0.95 +/- 0.95 mm in the placebo group (p = 0.003). There were no significant differences in plasma soluble Fas or soluble Fas ligand levels at baseline. At 6 months, the change in plasma soluble Fas level was signi...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Cardiovascular Diseases: Risk Factors

Cardiovascular disease is a significant health concern. Risk factors include hypertension, obesity, dyslipidemia and smoking. Women who are postmenopausal are at an increased risk of heart disease. Here is the latest research for risk factors of cardiovascular disease.
