Background:The mobile cloud electrocardiography (C-ECG) system is useful for reducing door-to-balloon (DTB) time in patients with acute coronary syndrome (ACS), but few studies have reported the usefulness of the C-ECG system across a wide provincial prefecture, such as Oita, in Japan.Methods and Results:On 17 April 2017, the C-ECG system was integrated into the Oita remote image transmission system, in 10 ambulances of 10 respective fire departments in Oita Prefecture. During 6 months, 162 ECG indicating suspected ACS were transmitted to 18 hospitals using the C-ECG system. Of 162 patients, 17 who received emergency percutaneous coronary intervention (PCI) were assigned to the cloud group (mean age, 71±11 years). The control group consisted of 29 consecutive ACS patients who were transported to Oita University Hospital without using the C-ECG system (mean age, 66±12 years). Another 40 consecutive patients were diagnosed with ACS before transportation to Oita University Hospital, and were assigned to the diagnosed group (mean age, 70±14 years). DTB time (70±26 min vs. 96±24 min, P<0.005) and door-to-catheterization laboratory time (33±20 min vs. 53±22 min, P<0.0001) were shorter in the cloud group than in the control group, respectively.Conclusions:C-ECG system integration in Oita Prefecture was useful to appropriately transfer ACS patients to hospital and to facilitate earlier PCI than in the conventional diagnostic system.

A 54-year-old man with early repolarization syndrome (ERS) implanted with an implantable cardioverter-defibrillator (ICD) developed persistent atrial fibrillation (AF) three years after the implantation. Similarly, the remote monitoring system begun frequently detecting ventricular fibrillation (VF) and polymorphic ventricular tachycardia (PVT). Longer RR intervals were repeatedly observed just before the initiation of PVT/VF. Catheter ablation for AF successfully diminished both the PVT and VF events.

Background: Cardiovascular autonomic neuropathy is a major complication in patients with diabetes mellitus (DM). However, the relationship between cardiovascular autonomic neuropathy and the incidence of cardiovascular events has been poorly investigated in type 2 DM. The present study aimed to assess the long-term cardiovascular predictive value of baroreflex sensitivity (BRS) in Japanese patients with type 2 DM without structural heart disease. Methods and Results: BRS was evaluated using the phenylephrine method in 210 patients with type 2 DM who did not have structural heart disease or other severe complications. BRS was considered depressed if <6 ms/mmHg. Accurate follow-up information for 3-10 years (mean 4.7 years) was obtained in 184 patients (90 females, 94 males; mean age 58±12 years). The initial onset of a major adverse cardiovascular event (MACE) was investigated. During follow-up, 19 patients presented with a MACE (4 cardiovascular deaths, 3 nonfatal myocardial infarctions, 4 coronary revascularizations, 5 strokes, 2 congestive heart failures). Cox proportional hazards regression analysis revealed that depressed BRS was independently associated with the incidence of MACE (hazard ratio 1.93, 95% confidence interval 1.09-3.82, P=0.0236). Conclusions: Depressed BRS at baseline has long-term cardiovascular predictive value in Japanese patients with type 2 DM without structural heart disease.  (Circ J 2010; 74: 1379 - 1383)
