Abstract

Coronary artery stenting has been shown to improve the short- and long-term results of coronary angioplasty in mainly stable patients with 1-vessel disease, but it is uncertain whether its use in an unstable clinical setting may be safe and useful. To evaluate the stenting efficacy in patients with unstable angina, we retrospectively examined our experience with the Palmaz-Schatz balloon expandable stent in 231 consecutive patients. Patients were divided into 2 groups on the basis of symptoms at the time of stent implantation: group U (132 patients) had unstable angina, and group S (99 patients) had stable angina. After stent insertion, patients were treated with anticoagulant or combined antiplatelet therapy. Baseline characteristics of the 2 groups were comparable with the exception of age (higher in the unstable group) and angiographic characteristics of the target lesions (more unfavorable in unstable patients). In both groups, coronary stenting presented a high procedural success rate. Major in-hospital complications occurred in 9 unstable (6.8%) and in 2 stable (2%) patients (p = NS) and were mainly related to subacute stent thrombosis. In both groups, subacute stent thrombosis mostly occurred in patients treated with ant...Continue Reading

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.
