anticoagulant therapy had been prescribed in 4 out of 38 patients in the intervention group and 2 out of 40 patients in the control group (10.5% vs 5.0%, p=0.425). Conclusions: Our preliminary results showed that among patients ≥55 years of age with a recent cryptogenic stroke or TIA, 30-day smartphone electrocardiogram recording significantly improved the detection of AF as compared with the standard repeat 24-hour Holter monitoring. However, there was no change in clinical practice in response to detection of AF. doi:10.1016/j.ijcard.2019.11.007 3.

Krishinan a a Department of Cardiology, Hospital Sultanah Bahiyah, Alor Setar, Kedah, Malaysia b Department of Medical, Hospital Pulau Pinang, Malaysia Background: Atrial fibrillation (AF) is the commonest sustained cardiac arrhythmia encountered in clinical practice. Current guidelines recommend opportunistic AF screening with pulse taking or ECG rhythm strips in patients N65 years of age. Systematic screening for AF at the community level with smartphone-based single-lead ECG (SL-ECG) has been studied and shown to pick up undiagnosed AF. The experience and data on the use of SL-ECG in community AF screening in the Asia Pacific region is scarce and may potentially identify undiagnosed AF for early treatment and stroke prevention. Objective: This is a prospective cross-sectional community-based study to assess the feasibility of community screening for AF using SL-ECG among senior citizens at Northern regions of West Malaysia. We aim to study the prevalence of AF detected by SL-ECG, total burden of AF among senior citizens at northern regions of West Malaysia and the predictors of AF. Methods: The study was conducted from 1st January 2018 to 31st December 2018. All consented senior citizens age 65 years old and above at northern regions of West Malaysia who had attended the selected clinics or community program were assessed by an interview questionnaire, followed by anthropometric measurements and then SL-ECG was performed. The ECGs are classified into three groups, namely sinus rhythm, AF and uninterpretable. Participants with uninterpretable SL-ECG will be referred for conventional 12- lead ECGs. Results: There were 2149 senior citizens consented to the study. Out of 2149 participants, 173(8%) were diagnosed with AF. 147 (6.8%)of them were detected via SL-ECG while 22 (1%) were self- reported and 4(0.2%) were detected via conventional 12-lead ECG. Out of 49(2.3%) newly diagnosed AF, 45(2.1%) were detected by SL-ECG while 4(0.2%) were detected via conventional 12-lead ECG. Using multiple logistic regression, the predictors of AF include state (pb0.001), gender (p=0.028), diabetes mellitus (p=0.017), heart failure (pb0.001), valvular heart disease(pb0.001), stroke (pb0.001) and thyroid disease (pb0.001). Conclusions: The prevalence of AF among senior citizens at Northern regions of West Malaysia was higher compared to the Western population. The opportunistic screening for AF detection by using SL-ECG in elderly were effective and feasible to be carried out. doi:10.1016/j.ijcard.2019.11.008 4. Utility of 2-Dimensional Speckle-Tracking Echocardiography to Predict Severity of Coronary Artery Disease in Patients With Non ST-Elevation Acute Coronary Syndrome and Apparent Normal Global and Segmental Systolic Function K.H.

Ong a a Cardiology Department, Sarawak Heart Centre, Sarawak b Faculty of Medicine and Health Sciences, University Malaysia Sarawak (UNIMAS) c Sarawak Clinical Research Centre, Sarawak General Hospital Background: In Non-ST-elevation acute coronary syndrome (NSTE-ACS), 2-dimensional (2D) speckle-tracking echocardiography (STE) may help to predict significant coronary stenosis or occlusion. The diagnostic value of STE (analysed using PhilipQlab) in Asians with NSTE-ACS and normal global and regional systolic function has not been reported. Objectives 1. To determine the correlation of Global Longitudinal Strain (GLS) with CAD severity in NSTE-ACS patients with normal LVEF. 2. To determine if GLS can prognosticate severity of CAD in comparison with TIMI and GRACE score. 3. To evaluate if Territory Longitudinal Strain (TLS) can be used as a predictor for myocardial territory involved. Materials and Methods: 200 AMI subjects admitted to Sarawak Heart Centre from May to September 2017 were screened. 45 patients with NSTE-ACS and normal left ventricular systolic function based on LVEF (≥55%) and WMSI (=1.0) were enrolled. Coronary angiography was performed during index admission. STE was done using PhilipQlabs version 10.0 for GLS and TLS. Syntax score was calculated with online calculator. Results: Majority were males (87%) with mean age of 57±8 years. 28.3% had diabetes. Majority had hypertension (58.7%), dys- lipidaemia (52.2%) and smoking (52.2%) as risk factors. 34.8% had single vessel disease (SVD) and 65.2% multi-vessels disease (MVD). Those with SVD and MVD had mean GLS of -20.9%±3.54% and -17.9%±4.47% respectively (p value =0.021). Syntax scores of 22 (63%) and N23 (37%) correlated with mean GLS of -20.7±3.37% and -15.9±4.36% respectively (Spearman’s =0.435). ROC curves for GLS vs TIMI vs GRACE score for predicting Syntax score were 0.811, 0.624 and 0.687 respectively. GLS of -18.4% had 73.3% sensitivity and 72.4% specificity in predicting Syntax score. TLS for Left Anterior Descending (LAD) territory had AUC 0.715. LAD TLS of -20.7% has 72.2% sensitivity and 70% specificity in predicting LAD myocardial territory involvement. Conclusions: In patient with NSTE-ACS and normal LVEF, GLS predicted severity of CAD and correlated moderately with Syntax score. GLS cut off of -18.4% is sensitive in predicting syntax score. TLS was useful to predict involvement of the LAD territory only. doi:10.1016/j.ijcard.2019.11.009 5.
