Among them, 5 were maleand ! was female; their age ranged from 28 to 66 years. Fourpatients had LAD stenosis and 2 LCX lesions.Acuteangiographic and clinical success was achieved in all patientsbut one, with a success rate Of 83.3%. It was demonstratedthat PTELCA is a safe and effective therapy for selected pa-tients with coronary artery disease.展开更多

In this article, we compared patients’ illness perception (IP), treatment adherence and coping mechanisms of patients undergoing percutaneous transluminal coronary angioplasty (PTCA). Methods: In this descriptive, prospective observational study IP, treatment adherence and coping of 140 patients were evaluated pre-PTCA, at the time of hospital discharge and 1 to 3 months post-PTCA by Illness Perception Questionnaire, Morisky Treatment Adherence and Carver’s brief COPE questionnaires. Results: 1 - 3 months post-PTCA, all dimensions of IP changed significantly except personal and treatment control. Adherence scores decreased simultaneously. With respect to coping mechanisms, all increased except behavioral disengagement, emotional support, instrumental support and religion which decreased significantly post-PTCA. Conclusions: In Overall, an improved IP and increased use of controllable causal attributions led to an increase in medication adherence and adaptive coping strategies. Post-treatment health behaviors are predictable by assessing patients’ illness-related beliefs beforehand.展开更多

Thepatient suffered from rest chest pain characterized by transient ST-segment elevation involving inferior leads.He had been frsequently attacked by syncope due to transient second degree or complete atrioventricular blockand ventricular tachycardia. Coronary arteriography revealed significant spasm in the midportion of the rightcoronary artery, which occurred at a mild fixed coronary obstructive lesion. The patient still had angina accompanied by syncope in hospital despite maximal drug therapy, so an intracoronary stent was implanted tothe patient. The patient was free of angina during a follow-up of 8 months thereafter.展开更多
