Acute cardiovascular complications of hemodialysis in patient with end-stage renal disease - a single center experience

Abstract

Hemodialysis (HD) is an important modality of renal replacement therapy and during HD, patients are at greater risk of cardiovascular complication compared with the general population, with estimated risk is as high as (8 to 20) fold. Most important cardiovascular complications during hemodialysis include; hypotension, arrhythmias, myocardial ischemia and heart failure. The aim of study is to evaluate patient on hemodialysis for occurrence of cardiovascular complication. One hundred patients on hemodialysis were enrolled in this study. Patients were evaluated for cardiovascular complication when they were undergoing hemodialysis through physical examination, electrocardiogram and echocardiography during their admission in hemodialysis unit. The age of the patients enrolled ranged from 30 to 75 years. The mean BMI was ranging from 19 to 29 kg/m2. In this study cardiovascular complications encountered are hypotension (the most frequent complication reported), followed by ventricular ectopic, angina, AF, SVT, LV dysfunction, peripheral vascular disease, AMI and stroke. Hypotension was significantly more in patients with UF >500 ml. Angina and PVD were significantly associated with graft type of venous access. Inconclusion: Hypotension was the most commonly reported cardiovascular complication of hemodialysis in patients who has had a high ultrafiltration rate; presence of other common comorbidity like diabetic mellitus, hypertension, and smoking increase the risk of angina, arrhythmia and infarction.
