ABSTRACT
Background: Worldwide primary angioplasty is a recommended strategy of reperfusion in patient with acute myocardial infarction as because it ensures reperfusion of the infarct-related vessels more than 90% where as, with thrombolytics it is only 60-70%. Methods: It is a retrospective observational study includes all patients treated with primary angioplasty at United Hospital from Between March 2007 to August 2010. Total 237 consecutive patients with acute myocardial infarction were treated with primary angioplasty were included. Those presented beyond 12 hours of onset of chest pain, in cardiogenic shock, resuscitate and intubated before the procedural were excluded from the study. Results: Majority (76%) of the patient were male, age was minimum 28 years and maximum 80 years, 41.5% were diabetics, 58.4% were hypertensive, 43.5 %were dyslipidaemic, 17% were smoker, 29.3% with positive family history. Fifty seven percent patients presented with anterior MI, 42 % with inferior MI and 1 % with lateral MI. Left anterior descending (LAD) is the most common vessel involved (S7%), followed by Right coronary artery (RCA) 31 %, Left circumflex artery (LCD 8 %, Ramus 1.3 % and Graft vessel 2.7%. Our door to balloon time was minimum 23 min, maximum 184 min. We used drug eluting stents for most of the patients , GP IIbIIIa receptor Mockers used in 50% cases and thrombus suction device were used when indicated. We faced complications like arrhythmias in 24% hypotension in18 %, no flow or slow flow in 45%, cardiac arrest in 3% and coronary perforation in 1. %. Our overall survival was 97.9 %. Conclusion: Primary angioplasty is a emerging area in the context 149-154of our country . Many of the new centers start this novel strategy which helps to save many lives. Primary angioplasty is feasible and safe method of reperfusion in patient with acute myocardial infarction in our center.
ABSTRACT
Background: Carotid angioplasty & stenting is becoming an emerging therapeutic option for carotid revascularization. The use of cerebral protection system has expanded the area of application of the procedure worldwide. Purpose: To assess the feasibility, success rate, safety as well as in-hospital & early 30 days outcome in patients undergoing percutaneous carotid intervention. Methods: A retrospective, observational study where a total of 18 (Eighteen) consecutive patients who presented with symptomatic and > 70 % carotid artery stenosis & asymptomatic but > 90% stenosis underwent percutaneous carotid intervention. All of them had coronary artery disease; CABG was done in 3 patients & PCI in 9 patients. Three of them had previous stroke (Ischemic) & 7 had TIA. Results: Technical and angiographic success was achieved in all patients. Carotid artery obstruction diminishes from 85 + 14 % to 10 + 5 % (p< .001). Mean lesion length was 12 + 3 mm and mean time of carotid occlusion during balloon inflation was 10 + 2.5 sec. distal protection devices used in all patents. No major stroke or death occurred during procedure. One patient developed No-flow because of obstruction of distal protection device which was managed by thrombosuction. One patient developed TIA. All patients were discharged from hospital after an average of 3 days & all of them were prescribed dual antiplatalet therapy for 6 months. During follow-up one patient died secondary to acute myocardial infarction and one patient developed major stroke. Conclusion: Percutaneous angioplasty and stenting associated with distal protective devices appear feasible, effective and almost safe endovascular treatment modality for carotid artery stenosis.
