Epidemiology of Arrhythmias and Sudden Cardiac Death in Asia

Left Atrial Function After Radiofrequency Catheter Ablation of Atrial Fibrillation – Can Pre-Ablation Function Predict Contractile Improvement During Follow-up? –

“…28- 30 We can only suppose that patients with impaired baseline LAEF have a thromboembolic risk higher than that estimated only with traditional risk factors: despite sinus rhythm, high LA volumes and decreased LAEF may cause stasis of blood within the LA and LA appendage, promoting thrombus formation. After ablation, these patients had an important increase in LAEF, which could decrease blood stasis and presumably reduce thromboembolic risk during follow-up.…”

High Prevalence of the <i>SCN5A</i> E1784K Mutation in School Children With Long QT Syndrome Living on the Okinawa Islands

“…19 Regarding the prevalence of LQT3 in other Asian countries such as Taiwan, China, and South Korea, we speculate that the high prevalence of LQT3 is similar to that of BrS in Asia. 20 To the best of our knowledge, only a limited number of reports have addressed the prevalence of LQT3 in Asian countries. For example, the SCN5A mutation was detected in 17.5% of all genotyped patients with LQTS residing in South Korea.…”

Peer Review #3 of "Comparison of ventricular tachyarrhythmia recurrence between ischemic cardiomyopathy and dilated cardiomyopathy: a retrospective study (v0.1)"

“…Ventricular tachyarrhythmias are significantly associated with increased risks of cardiovascular complications and sudden cardiac death (SCD), consequently leading to a decreased quality of life and increased disability, high mortality, and greater healthcare expenses. In Asia, SCD occurs in approximately 40 cases per 100,000 individuals annually, and most cases of SCD are caused by myocardial infarction and ventricular tachycardia (VT)/ ventricular fibrillation (VF) (Murakoshi et al, 2013). Implantation of an Iimplantable cardioverter-defibrillator (ICD) implantation has been established as an effective secondary prevention strategy for SCD, and the number of ICD implantations has increased gradually because more and more patients with post-myocardial infarction and heart failure (HF) survive with contemporary optimal medical therapies, including ß-blockers, renin-angiotensin-aldosterone antagonists, and statins, as well as modifications of risk factors (Borne et al, 2017).…”
