[The no-reflow phenomenon: its incidence and clinical characteristics in a series of cases].
The no-reflow phenomenon refers to the inability to reperfuse myocardial tissue despite removal of an occlusion of a coronary artery. No reflow is a complication that may occur after revascularization of patients. This study examined the incidence and, clinical characteristics of no-reflow in a patient population treated with conventional percutaneous transluminal coronary angioplasty at the Instituto Nacional de Cardiología "Ignacio Chávez". We reviewed 204 elective angioplasties and 62 direct angioplasties; 14 patients were included (4 from the first group and 10 from the second group). No-reflow were more frequently in men, the mean age was 56 years and diabetes and smoking were the risk factors more frequently reported. No-reflow was found in left anterior descending coronary artery in 7 patients, the time of reperfusion, in direct angioplasty, was 10.6 hours (mean) and the strategy most frequently used to reestablish normal anterograde flow was intracoronary verapamil. The overall incidence of no-reflow for the two modalities was 5.2% (16.12% for direct angioplasty and 1.9% for elective angioplasty). The current study shows that the no-reflow phenomenon is not uncommon after angioplasty; no-reflow appears higher than the previous reports for both modalities of treatment.
