“…Furthermore, Japanese physicians tend to believe that Japanese patients have a lower risk of IHD and decreased LVEF than those of western countries [24]. Indeed, Japanese patients who had received intracoronary thrombosis or an emergent and/or elective percutaneous transluminal coronary angioplasty, had a favorable prognosis [30]. Furthermore, the presence of non‐sustained VT was a significant predictor of death ( p =0.036) only in the patients who did not receive acute reperfusion, and the percentage of patients with LVEF<35% was only 5.7% at 13±8 days after myocardial infarction [31].…”

a b s t r a c tPurpose: The aim of this study was to describe the recent conditions associated with implantable defibrillation therapy for individual underlying heart diseases. Methods: Ten thousand six hundred and five patients with implantable cardioverter-defibrillators (ICDs) or cardiac resynchronization therapy defibrillators (CRT-Ds) that were implanted from 2006 to 2010 were selected from the Japan Cardiac Device Therapy Registry database. They were divided into 12 disease categories and further divided into either primary or secondary prevention of sudden cardiac death. Results: The major underlying diseases of the patients in this cohort were ischemic heart disease (IHD, 35%), dilated cardiomyopathy (DCM, 25%), hypertrophic cardiomyopathy (HCM, 8%), and Brugada syndrome (Brugada, 8%). There were no structural heart diseases in this cohort; the incidence of IHD was relatively lower than that of western countries, while the incidence of cardiomyopathy was higher. The percentage of primary prevention (% primary) among the individual diseases varied. IHD was the most prevalent underlying condition in the patient cohort; however, the % primary was 33%, which was relatively lower than that of the other structural heart diseases. The % primary was relatively higher in patients with DCM (57%) and Brugada (47%). Over 5 years, the % primary gradually increased in patients with DCM, IHD, and HCM, with a particularly dramatic increase in those with DCM. A decrease in the % primary among patients with Brugada began in 2008. Conclusions: In patients that underwent implantable defibrillation therapy, there was a relatively lower % primary in the IHD group, and a substantial increase in the % primary in patients with DCM.

“…We therefore considered the case-fatality rate of MI to be 0.23 in the first year after AMI. For the case-fatality rate of MI within 2 to 5 years after AMI, we used the 5-year mortality rates of MI (0.07 for men and 0.11 for women) derived from an observational study of 2733 Japanese patients [20]. After 6 years, we assumed that the annual mortality rate among patients with MI was similar to that in general population as estimated from Japanese Life Tables for 2002 [2].…”

“…There is little data available regarding the role of clinical examination upon hospital arrival on the long‐term prognosis after myocardial infarction. Hosoda et al [31] observed an excellent correlation between long‐term survival at a mean follow‐up of 2.9 years and either Killip's or Forrester's classification upon hospital admission, in patients with acute myocardial infarction subjected to emergency coronary arteriography. Of these, 25% were treated concomitantly with intracoronary thrombolysis and 15% were treated concomitantly with primary coronary angioplasty.…”

Background: Modern and sophisticated technology for the management of myocardial infarction has progressively devalued medical evaluation. Hypothesis: This study was undertaken to assess the importance of the findings of medical evaluation at hospital presentation, in patients with acute myocardial infarction. Methods: Data from 590 thrombolytic-treated myocardial infarction patients were analyzed. The patients were grouped according to their clinical status on arrival at hospital. A Ž . Ž . modified Forrester classification ᎏ subset II was divided according to the absence IIa or presence IIb of symptoms ᎏ was Ž . Ž . applied. Short-14 days and long-term up to 10 years survival was analyzed and 19 independent variables were included in the multivariate models. Results: Short-term survival was 95.6% for subset I, 83.3% for subset IIa, 60% for subset IIb, 54.6% Ž . Ž . for subset III, and 34.8% for subset IV P-0.001 . By multiple regression analysis, lower clinical subsets P-0.001 , fewer Ž . Ž . Ž . coronary arteries with disease Ps 0.006 , younger age Ps 0.014 , absence of reinfarction P s 0.034 , longer interval Ž . Ž . between streptokinase infusion and coronary arteriography P s 0.016 , and higher left ventricular ejection fraction Ps 0.037 demonstrated significant and independent correlation with short-term survival. Long-term survival for the total population was 71 " 3.6% for subset I, 54.4" 8.5% for subset IIa, 20.8" 9.4% for subset IIb, 54.5" 15% for subset III, and 0% for subset IV Ž . Ž . Ž . P-0.001 . Using Cox regression analysis, lower clinical subsets P-0.001 , younger age P -0.001 , higher global left Ž . Ž . ventricular ejection fraction P-0.001 , and fewer coronary arteries with disease P s 0.021 correlated independently and Ž . significantly with long-term survival. When excluding data from patients who died before the short-term follow-up n s 532 , Ž . lower clinical subsets remained an important predictor of long-term survival P -0.001 . Conclusion: Clinical classification at hospital presentation is a powerful predictor of short-and long-term survival post-myocardial infarction. ᮊ
