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.

Background: We have reported that a prehospital 12-lead electrocardiography system (P-ECG) contributed to transport of suspected acute coronary syndrome (ACS) patients to appropriate institutes and in this study, we compared its usefulness between urban and rural areas, and between weekday daytime and weekday nighttime/holiday.Methods and Results: Consecutive STEMI patients who underwent successful primary percutaneous coronary intervention after using P-ECG were assigned to the P-ECG group (n=123; 29 female, 70±13 years), and comparable STEMI patients without using P-ECG were assigned to the conventional group (n=117; 33 females, mean age 70±13 years). There was no significant difference in door-to-reperfusion times between the rural and urban cases (70±32 vs. 69±29 min, P=0.73). Door-to-reperfusion times in the urban P-ECG group were shorter than those in the urban conventional group for weekday nighttime/holiday (65±21 vs. 83±32 min, P=0.0005). However, there was no significance different between groups for weekday daytime. First medical contact to reperfusion time (90±22 vs. 105±37 min, P=0.0091) in the urban P-ECG group were significantly shorter than in the urban conventional groups for weekday nighttime/holiday, but were not significantly different between the groups for weekday daytime.Conclusions: P-ECG is useful even in urban areas, especially for patients who develop STEMI during weekday nighttime or while on a holiday.

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)
