Empagliflozin has favourable effect on frontal plane QRS‐T angle in diabetic patients with cardiovascular disease

alexandrossfakianakis shared this article with you from Inoreader Empagliflozin has favourable effect on frontal plane QRS‐T angle in diabetic patients with cardiovascular disease via Journal of Clinical Pharmacy and Therapeutics Empagliflozin treatment is associated with a significant decrease in the frontal plane QRS-T angle (fQRST) in patients with diabetes mellitus (DM). However, despite similar antihyperglycemic effect with empagliflozin treatment in patients with and without cardiovascular disease (CVD), the significant decrease in fQRST angle was observed only in patients with CVD and no significant decrease was observed in fQRST angle in patients without CVD. Therefore, as a sign of ventricular repolarization heterogeneity that can be easily measured from a standard 12-lead electrocardiography (ECG), fQRST angle may be a useful ECG parameter in the monitoring of cardiovascular effects of empagliflozin in type 2 DM patients with CVD. Abstract What is Known and Objective Empagliflozin treatment is significantly associated with lower risk of cardiovascular events in patients with diabetes mellitus (DM) independent of its antihyperglycemic effect. However, little is known regarding the impact of empagliflozin on electrocardiography (ECG) parameters. This study aimed to investigate whether empagliflozin has favourable effect on frontal plane QRS-T (fQRST) angle, which is an ECG sign of ventricular repolarization heterogeneity, in patients with type 2 DM. Methods We prospectively enrolled 111 patients with known diagnosis of type 2 DM who newly prescribed empagliflozin on top of their standard anti-diabetic therapy. Patients were divided into two groups according to presence or absence of cardiovascular disease (CVD) at baseline and followed-up for 6 months. The impact of empagliflozin treatment on fQRST angle was investigated and patient groups were compared regarding the pre- and post-treatment fQRST angle. Results and Discussion Among 111 patients, 32 (28.8%) had CVD and 79 (71.2%) had no CVD. Empagliflozin treatment lead a significant decrease in the mean fQRST angle throughout the study period and mean fQRST angle was significantly lower at 3- and 6-month follow-up visits compared to baseline values (62° ± 17.4° vs. 57.2° ± 14.8° vs. 50.5° ± 13.6°, p < 0.001 for all dual comparisons). However, despite similar antihyperglycemic effect with empagliflozin treatment in patients with and without CVD, the significant decrease in the mean fQRST angle was observed only in patients with CVD and no significant decrease was observed in the mean fQRST angle in patients without CVD. What is New and Conclusion Empagliflozin leads a significant narrowing in the fQRST angle in type 2 DM patients with known CVD. View on Web
