RESUMO
Background: Percutaneous coronary intervention (PCI) has been an effective and widely used treatment for patients with coronary artery disease (CAD). The presence of anaemia in critically ill patients undergoing surgical procedures has been associated with worse clinical outcomes. Hence, the current study was conducted to assess short term outcome of percutaneous coronary interventions in anaemic patients presenting with coronary artery diseases. Methods: This prospective observational study enrolled 200 patients who underwent PCI. Patients were classified into 2 groups: anaemic patients and non-anaemic patients. The anaemic patients were furtherly be classified according to severity of anaemia into 3 grades mild anaemia, moderate anaemia, and severe anaemia. All cases were subjected to complete history taking, clinical examination and baseline laboratory tests: including CBC, serum urea and creatinine, cardiac enzymes include serum troponin, CK-MB and standard 12-lead ECG. Results: The mean Heart Rate was statistically significantly higher in the anaemic group as compared with the non-anaemic group. The mean Ejection Fraction was statistically significantly lower in the anaemic group as compared with the non-anaemic group. The percentage of LM affection in the anaemic group was statistically significantly higher as compared with the non-anaemic group. The incidence of arrythmia in the anaemic group was statistically significantly higher as compared with the non-anaemic group. Severe anaemic and low EF% patients were associated with higher incidence of stroke and MI. Conclusions: Patients with baseline anaemia before PCI have a higher incidence of PCI associated complications. Therefore, anaemia could be a predictor of PCI related complications.
RESUMO
Background: This study describes cardiac pacing activity during 2021: demographic data of patients underwent permanent pacemaker implantation (PPM), risk factors, clinical presentations, indications, mode of pacing, and complications post PPM implantation. Cardiac pacemakers have become the common treatment of symptomatic bradycardia or high-grade atrioventricular block. Methods: The study was carried out at the department of cardiology Tanta University Hospitals. 102 patients were included in this study. This study was done over a period of six months from October 2020 until April 2021 and follow up for 6 months. All the data about the patients underwent permanent pacemaker implantation were collected by the coordinator in the participating cardiac center. Results: The most frequent risk factors of PPM implantation was hypertension (69%), followed by diabetes mellitus (29%), coronary artery disease (21%), chronic kidney disease (18%), hypothyroidism (6%), cardiomyopathy (3%), valvular heart disease (2%) and congenital heart disease (1%). The most common indication is complete heart block (69%), followed by second degree heart block "mobeitz type 2" (13%), slow atrial fibrillation (7%), symptomatic heart failure patients with LVEF ? 35% , QRS ? 150 ms (6%), trifascicular block (3%), sick sinus syndrome (2%). The most frequent mode of pacing used in our study was DDD mode (63%), followed by VVI mode (32%) with (78%) sinus rhythm and (22%) atrial fibrillation rhythm, then CRT-D (4%). Overall complication rate (9%) within 6 months. In our study the most common complication is infection (5%), followed by haematoma (1%), lead fracture (1%), pneumothorax (1%), and lead displacement (1%). Conclusion: Approximately three-quarters of the patients related to atrioventricular block underwent permanent pacemaker implantaion. Approximately more than half of pacemakers related to patients underwent permanent pacemaker implantation were dual chamber pacemakers. Infection is the most common complication in our study and this is important for strict infection control measures.
