Clinical profile, management and outcome of pulmonary embolism in Shahid Gangalal National Heart Centre, Kathmandu, Nepal

Abstract

Background and aimsPulmonary embolism (PE) is associated with a significant mortality and morbidity. We aim to study clinical profile, management and outcome of PE at Shahid Gangalal National heart Centre, Kathmandu, Nepal.MethodsIt was a retrprospective, single centre study, conducted from January 2015 to December 2016. Haemodynamics was used for risk Simplified, PESI score, predisposing factors, symptoms, clinical features at the time of admission, ECG features, echocardiogram, treatment received and the outcome were reviewed.ResultsDuring the study period 23 cases of PE were admitted. Nine were males and 14 were females. Eleven patients were diagnosed as provoked PE. High risk PE was diagnosed in four patients, Non-high risk in 19 patients. The most common clinical presentation was shortness of breath. The most common finding in ECG is sinus tachycardia followed by ST-T changes in V1-V3. Eight patient had SPO2 less than 90%. Most of the patients had a normal chest radiograph. Echocardiography revealed dilated RA and RV in 20 patients.All high risk PE patients were thrombolyzed with streptokinase. All patients who were diagnosed as Non-high risk PE were treated with LMWH. All the patients were treated with oral anticoagulants. Mean hospital stay was 9.7 ± 4.9 days. Two patients died during hospital stay. S-PESI score was 1.4 ± 0.9 respectively. Mean warfarin dose at the time of discharge was 5.9 ± 1.6 mg.ConclusionPE is an under diagnosed clinical problem world over. Suspicion is the most important part to come to the diagnosis of PE.

Coronavirus disease 2019 death prediction by electrocardiographic abnormalities and elevated D-dimer levels

“…A study of 177 cases demonstrated that the proportion of ST-T changes on ECG was 49.15% in patients with PE ( 27 ). ST-T abnormalities are most common in precordial leads V 1 -V 3 on ECG in PE ( 28 ). Figure 4 also shows that inversion T-waves occurred in the right precordial leads, which might be associated with the right myocardial strain.…”
