Abstract
BACKGROUND Polypharmacy was reported to be associated with major bleeding in various populations. However, there are no data on polypharmacy and its association with bleeding in patients undergoing percutaneous coronary intervention (PCI).Methods and Results: Among 12,291 patients in the CREDO-Kyoto PCI Registry Cohort-3, we evaluated the number of medications at discharge and compared major bleeding, defined as Bleeding Academic Research Consortium Type 3 or 5 bleeding, across tertiles (T1-3) of the number of medications. The median number of medications was 6, and 88.0% of patients were on ≥5 medications. The cumulative 5-year incidence of major bleeding increased incrementally with increasing number of medications (T1 [≤5 medications] 12.5%, T2 [6-7] 16.5%, and T3 [≥8] 20.4%; log-rank P<0.001). After adjusting for confounders, the risks for major bleeding of T2 (hazard ratio [HR] 1.21; 95% confidence interval [CI] 1.08-1.36; P=0.001) and T3 (HR 1.27; 95% CI 1.12-1.45; P<0.001) relative to T1 remained significant. The adjusted risks of T2 and T3 relative to T1 were not significant for a composite of myocardial infarction or ischemic stroke (HR 0.95 [95% CI 0.83-1.09; P=0.47] and HR 1.06 [95% CI 0.91-1.23; P=0.48], respectively). CONCLUSIONS In a real-world population of patients undergoing PCI, approximately 90% were on ≥5 medications. Increasing number of medications was associated with a higher adjusted risk for major bleeding, but not ischemic events.

Abstract
It is important to clarify the precise impact of mitral regurgitation (MR) on long-term outcomes in acute myocardial infarction (AMI) patients who underwent percutaneous coronary intervention (PCI). In the Coronary Revascularization Demonstrating Outcome study in Kyoto Acute Myocardial Infarction (CREDO-Kyoto AMI) Registry Wave-2, the study population consisted of 5,266 patients with AMI who underwent PCI. The clinical outcomes of all-cause death, cardiovascular death, and hospitalization for heart failure (HF) were compared according to the severity of MR. Mild and moderate/severe MR were identified in 2,112 (40%) and 531 patients (10%), respectively. Patients with greater severity of MR were more likely to be old, had more co-morbidities, and more often presented with large myocardial infarction with HF. During median follow-up duration of 5.6 (interquartile range: 4.2 to 6.6) years, as the MR severity increased from no, mild, to moderate/severe MR, the cumulative 5-year incidences of all-cause death, cardiovascular death and hospitalization for HF incrementally increased ([15.3%, 19.6%, 33.3%], [8.9%, 11.7%, 21.0%] and [5.9%, 12.4%, 23.9%], respectively, P for all<0.001). After adjusting for confounders, however, mild and moderate/severe MR were not independently associated with the higher risks for all-cause death (hazard ratio [95% confidence interval]:1.05 [0.92 to 1.19], p = 0.51, and 1.10 [0.92 to 1.32], p = 0.28) and cardiovascular death (1.01 [0.85 to 1.21], p = 0.89, and 0.93 [0.73 to 1.18], p = 0.54) as compared with no MR. Both mild and moderate/severe MR were independently associated with the higher risks for hospitalization for HF (1.73 [1.42 to 2.11], p <0.001, and 2.23 [1.73 to 2.87], p <0.001). In a large population of patients with AMI who underwent PCI, MR was not independently associated with higher long-term mortality risk but was independently associated with higher risk for hospitalization for HF.

Abstract
Aims There is a scarcity of studies comparing percutaneous coronary intervention (PCI) using new-generation drug-eluting stents (DES) with coronary artery bypass grafting (CABG) in patients with multi-vessel coronary artery disease. Methods and results The CREDO-Kyoto PCI/CABG registry Cohort-3 enrolled 14927 consecutive patients who underwent first coronary revascularization with PCI or isolated CABG between January 2011 and December 2013. The current study population consisted of 2464 patients who underwent multi-vessel coronary revascularization including revascularization of left anterior descending coronary artery (LAD) either with PCI using new-generation DES (N = 1565), or with CABG (N = 899). Patients in the PCI group were older and more often had severe frailty, but had less complex coronary anatomy, and less complete revascularization than those in the CABG group. Cumulative 5-year incidence of a composite of all-cause death, myocardial infarction or stroke was not significantly different between the 2 groups (25.0% versus 21.5%, P = 0.15). However, after adjusting confounders, the excess risk of PCI relative to CABG turned to be significant for the composite endpoint (HR 1.27, 95%CI 1.04–1.55, P = 0.02). PCI as compared with CABG was associated with comparable adjusted risk for all-cause death (HR 1.22, 95%CI 0.96–1.55, P = 0.11), and stroke (HR 1.17, 95%CI 0.79–1.73, P = 0.44), but with excess adjusted risk for myocardial infarction (HR 1.58, 95%CI 1.05–2.39, P = 0.03), and any coronary revascularization (HR 2.66, 95%CI 2.06–3.43, P<0.0001). Conclusions In this observational study, PCI with new-generation DES as compared with CABG was associated with excess long-term risk for major cardiovascular events in patients who underwent multi-vessel coronary revascularization including LAD.

Abstract
BACKGROUND Diabetes is a well-known risk factor for adverse outcomes after coronary revascularization. OBJECTIVES This study sought to determine high-risk subgroups in whom the excess risks of diabetes relative to nondiabetes are particularly prominent and thus may benefit from more aggressive interventions. METHODS The study population consisted of 39,427 patients (diabetes: n = 15,561; nondiabetes: n = 23,866) who underwent first percutaneous coronary intervention (n = 33,144) or coronary artery bypass graft (n = 6,283) in the pooled CREDO-Kyoto PCI/CABG (Coronary Revascularization Demonstrating Outcome Study in Kyoto Percutaneous Coronary Intervention/Coronary Artery Bypass Graft) registry. The primary outcome measure was major adverse cardiovascular and cerebral endpoints (MACCE), which was defined as a composite of all-cause death, myocardial infarction, and stroke. RESULTS With median follow-up of 5.6 years, diabetes was associated with significantly higher adjusted risks for MACCE. The excess adjusted risks of diabetes relative to nondiabetes for MACCE increased with younger age (≤64 years: adjusted HR: 1.30; 95% CI: 1.19-1.41; P < 0.001; 64-73 years: adjusted HR: 1.24; 95% CI: 1.16-1.33; P < 0.001; >73 years: adjusted HR: 1.17; 95% CI: 1.10-1.23; P < 0.001; P interaction < 0.001), mainly driven by greater excess adjusted mortality risk of diabetes relative to nondiabetes in younger tertile. No significant interaction was observed between adjusted risk of diabetes relative to nondiabetes for MACCE and other subgroups such as sex, mode of revascularization, and clinical presentation of acute myocardial infarction. CONCLUSIONS The excess risk of diabetes relative to nondiabetes for MACCE was profound in the younger population. This observation suggests more aggressive interventions for secondary prevention in patients with diabetes might be particularly relevant in younger patients.

Abstract
BACKGROUND Optimal intensity is unclear for P2Y12receptor blocker therapy after percutaneous coronary intervention (PCI) in real-world clinical practice.Methods and Results:From the CREDO-Kyoto Registry, the current study population consisted of 25,419 patients (Cohort-2: n=12,161 and Cohort-3: n=13,258) who underwent their first PCI. P2Y12receptor blocker therapies were reduced dose of ticlopidine (200 mg/day), and global dose of clopidogrel (75 mg/day) in 87.7% and 94.8% of patients in Cohort-2 and Cohort-3, respectively. Cumulative 3-year incidence of GUSTO moderate/severe bleeding was significantly higher in Cohort-3 than in Cohort-2 (12.1% and 9.0%, P<0.0001). After adjusting 17 demographic factors and 9 management factors potentially related to the bleeding events other than the type of P2Y12receptor blocker, the higher bleeding risk in Cohort-3 relative to Cohort-2 remained significant (hazard ratio (HR): 1.52 95% confidence interval (CI) 1.37-1.68, P<0.0001). Cohort-3 compared with Cohort-2 was not associated with lower adjusted risk for myocardial infarction/ischemic stroke (HR: 0.96, 95% CI: 0.87-1.06, P=0.44). CONCLUSIONS In this historical comparative study, Cohort-3 compared with Cohort-2 was associated with excess bleeding risk, which might be at least partly explained by the difference in P2Y12receptor blockers.

Abstract
There is a scarcity of data comparing long-term clinical outcomes between percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) in patients with three-vessel coronary artery disease (3VD) in the new-generation drug-eluting stents era. CREDO-Kyoto PCI/CABG registry Cohort-3 enrolled 14927 consecutive patients who had undergone first coronary revascularization with PCI or isolated CABG between January 2011 and December 2013. We identified 2525 patients with 3VD (PCI: n = 1747 [69%], and CABG: n = 778 [31%]). The primary outcome measure was all-cause death. Median follow-up duration was 5.7 (interquartile range: 4.4 to 6.6) years. The cumulative 5-year incidence of all-cause death was significantly higher in the PCI group than in the CABG group (19.8% vs 13.2%, log-rank p = 0.001). After adjusting confounders, the excess risk of PCI relative to CABG for all-cause death remained significant (HR, 1.45; 95% CI, 1.14 to 1.86; p = 0.003), which was mainly driven by the excess risk for non-cardiovascular death (HR, 1.88; 95% CI, 1.30 to 2.79; p = 0.001), while there was no excess risk for cardiovascular death between PCI and CABG (HR, 1.19; 95% CI, 0.87 to 1.64; p = 0.29). There was significant excess risk of PCI relative to CABG for myocardial infarction (HR, 1.77; 95% CI, 1.19 to 2.69; p = 0.006), whereas there was no excess risk of PCI relative to CABG for stroke (HR, 1.24; 95% CI, 0.83 to 1.88; p = 0.30). In conclusion, in the present study population reflecting real-world clinical practice in Japan, PCI compared with CABG was associated with significantly higher risk for all-cause death, while there was no excess risk for cardiovascular death between PCI and CABG.

Abstract
BACKGROUND The prevalence of and expected bleeding event rate in patients with the Japanese version of high bleeding risk (J-HBR) criteria are currently unknown in real-world percutaneous coronary intervention (PCI) practice.Methods and Results:We applied the J-HBR criteria in the multicenter CREDO-Kyoto registry cohort-3 that enrolled 13,258 consecutive patients who underwent first PCI. The J-HBR criteria included Japanese-specific major criteria such as heart failure, low body weight, peripheral artery disease and frailty in addition to the Academic Research Consortium (ARC)-HBR criteria. There were 8,496 patients with J-HBR, and 4,762 patients without J-HBR. The J-HBR criteria identified a greater proportion of patients with HBR than did ARC-HBR (64% and 48%, respectively). Cumulative incidence of the Bleeding Academic Research Consortium (BARC) type 3 or 5 bleeding was significantly higher in the J-HBR group than in the no-HBR group (14.0% vs. 4.1% at 1 year; 23.1% vs. 8.4% at 5 years, P<0.0001). Cumulative 5-year incidence of BARC 3/5 bleeding was 25.1% in patients with ARC-HBR, and 23.1% in patients with J-HBR. Cumulative incidence of myocardial infarction or ischemic stroke was also significantly higher in the J-HBR group than in the no-HBR group (6.9% vs. 3.6% at 1 year; 13.2% vs. 7.1% at 5 years, P<0.0001). CONCLUSIONS The J-HBR criteria successfully identified those patients with very high bleeding risk after PCI, who represented 64% of patients in this all-comers registry.

Abstract
We herein report a case of congenital long QT syndrome (LQTS) in which the QT interval was prolonged by Takotsubo syndrome (TTS), inducing ventricular fibrillation (VF). The patient was a 55-year-old woman who had been diagnosed with LQTS. Cardiopulmonary arrest occurred while coughing during sleep. VF was observed, and her heartbeat returned after two defibrillations. An electrocardiogram showed marked QT prolongation and large negative T waves. Echocardiography demonstrated hyperkinesis at the base of the left ventricle and akinesis at the apex. As there was no significant stenosis in the coronary artery, she was diagnosed with TTS.

Abstract
We herein describe an adult case of double-chambered right ventricle (DCRV) with symptomatic drug-intolerant paroxysmal atrial fibrillation (PAf). The woman was referred to undergo radiofrequency ablation (RFA), and mapping of the pulmonary veins (PVs) demonstrated that a spontaneous spike potential originating from the left inferior PV (LIPV) induced sustained Af in the second procedure. Accordingly, the LIPV was regarded as the arrhythmogenic PV. Since complete isolation of the PVs, the sinus rhythm has been maintained for at least two years. This is the first report to describe that RFA for drug-intolerant PAf was useful in a patient with DCRV.

Abstract
BACKGROUND The Japan Atherosclerosis Society's 2007 Guidelines for Prevention of Atherosclerotic Cardiovascular Diseases (JAS2007GL) advocate reducing LDL cholesterol (LDL-C) to target levels in patients with dyslipidemia, but achievement rates are frequently unsatisfactory even in the presence of lipid-lowering therapy. This multicenter, open-label, randomized, parallel-group study compared the efficacy of rosuvastatin and atorvastatin on JAS2007GL LDL-C goals in Japanese patients not achieving their target goal with atorvastatin treatment. METHODS The study involved 20 clinical institutes in Japan (Kishiwada Atherosclerosis Prevention Study [KAPS] Group). Patients with category II or III risk of coronary artery disease (CAD), or those with a history of CAD (secondary prevention), who had not achieved their JAS2007GL LDL-C goals during treatment with atorvastatin for at least 4 weeks were switched either to rosuvastatin 5 mg/day (from atorvastatin 10 mg/day) or rosuvastatin 10 mg/day (from atorvastatin 20 mg/day) (n = 75) or continued to receive atorvastatin (n = 77). The primary endpoint was achievement of LDL-C goals at 3 months. The main secondary endpoint was achievement of LDL-C goal + high-sensitivity C-reactive protein level <1.0 mg/L at 3 months. RESULTS Achievement rates for the primary endpoint were 49.3% in the rosuvastatin group and 31.7% in the atorvastatin group (P = 0.022). Achievement rates for the main secondary endpoint were 40.0% in the rosuvastatin group and 20.8% in the atorvastatin group (P = 0.010). Rosuvastatin and atorvastatin were both well tolerated in this study. CONCLUSIONS Rosuvastatin is a useful treatment option for Japanese patients who are not achieving their JAS2007GL LDL-C goal with atorvastatin.

Abstract
We report a case of a 50-year-old man with intractable hypotension, which led to ischemic electrocardiogram (ECG) changes and myocardial injury due to relative myocardial ischemia as a result of a disulfiram-ethanol reaction. This is the first report that assessed cardiac function during hypotension and ischemic ECG changes by emergency coronary angiography, left ventriculography, and right heart catheterization. This case indicates that disulfiram potentially has fatal side effects due to a disulfiram-ethanol reaction.

Abstract
BACKGROUND The cardio-ankle vascular index (CAVI) has been recently reported as a new index of aortic stiffness, which is less influenced by blood pressure than pulse wave velocity (PWV). The present study investigated the relationship between the levels of CAVI and carotid and coronary arteriosclerosis. METHODS AND RESULTS The 443 consecutive patients who underwent CAVI, carotid sonography, and coronary angiography in hospital were examined. Intima-media thickness (IMT) and carotid plaque were evaluated by ultrasonography. The severity of coronary artery disease (CAD) was evaluated by coronary angiography and the subjects were divided into 4 groups (0, no significant organic stenosis: 1, 1-vessel disease: 2, 2-vessel disease: 3, 3-vessel disease). Univariate analyses showed that both CAVI and brachial-ankle PWV (baPWV) were associated with IMT and the presence of carotid plaque. Multiple stepwise regression analyses revealed that CAVI (p=0.0427), but not baPWV, was associated with the IMT. Both CAVI (p<0.0001) and baPWV (p=0.0140) were significantly associated with the severity of CAD. Multiple logistic analyses revealed that CAVI (p=0.0342), but not baPWV (p=0.8027), was associated with the presence of multivessel disease. CONCLUSION High CAVI implies progression of carotid and coronary arteriosclerosis. CAVI may be more closely linked with arteriosclerosis than baPWV.

Abstract
BACKGROUND Hypoadiponectinemia has been reported to indicate an increased risk of cardiovascular disease, so the present study investigated the significance of serum adiponectin (APN) levels for predicting clinical outcomes after percutaneous coronary intervention (PCI). METHODS AND RESULTS The APN levels were evaluated in 184 consecutive patients who underwent PCI. The patients were divided into Group A [the lowest quartile of APN levels (APN < or =4.5 microg/ml), n=46] and Group B [the upper 3 quartiles of APN levels (APN >4.5 microg/ml), n=138]. During a mean follow-up period of 27.3 months, the rate of major adverse cardiac and cerebrovascular events (MACCE: death from any cause, re-infarction, repeat coronary revascularization, hospitalization because of congestive heart failure, and cerebral infarction) was higher in Group A (58.7%) than in Group B (37.0%, p=0.0101). Moreover, when the APN levels were calculated by adjusting for sex, age, body mass index, and triglyceride levels, patients in the lowest quartile of residual APN levels had a higher risk of MACCE (p=0.0405). Multiple logistic analyses showed that hypoadiponectinemia (APN < or =4.5 microg/ml) was independently correlated with MACCE. Kaplan-Meier analysis demonstrated a higher MACCE rate in Group A than in Group B (Log-rank chi(2)=7.89, p=0.0050). CONCLUSION The APN level may be helpful for predicting clinical outcomes after PCI.

Abstract
OBJECTIVES Adiponectin is an adipocyte-derived endocrine factor. Hypoadiponectinemia has been observed in obese patients, and plasma adiponectin levels are reported to increase during weight reduction. Moreover, hypoadiponectinemia has also been observed in patients with coronary artery diseases. The present study investigated the relationships between levels of adiponectin and carotid intimal-medial thickness, a marker of early vascular disease, and carotid artery plaque and the severity of coronary artery disease, a marker of advanced vascular disease. METHODS Four hundred thirty-one consecutive patients were enrolled from inpatients without acute coronary syndrome who underwent coronary angiography between August 2001 and August 2003. The residual adiponectin levels were calculated by adjusting for sex, age, and body mass index, and a logarithmic transformation was applied. The severity of coronary artery disease was evaluated by coronary angiography and divided into four groups (Group 0: no significant organic stenosis, Group 1: 1-vessel disease, Group 2: 2-vessel disease, Group 3: 3-vessel disease or left main coronary trunk disease). Carotid plaque was evaluated by ultrasonography and divided into two groups [Group(-) : patients without carotid plaque, Group (+): patients with carotid plaque]. The intimal-medial thickness was measured on a longitudinal scan of the common carotid artery at a point 1 cm proximal from the bifurcation bulb. RESULTS The logarithmic-transformed levels of residual adiponectin were associated with severity of coronary artery disease (Group 0: 0.18 +/- 0.59 microg/ml, Group 1: -0.02 +/- 0.56 microg/ml, Group 2: - 0.09 +/- 0.58 microg/ml, Group 3: - 0.10 +/- 0.66 microg/ml, p = 0.0013). The logarithmic-transformed levels of residual adiponectin were decreased in patients with carotid plaque [Group (-): 0.08 +/- 0.59 microg/ml, Group (+): - 0.08 +/- 0.59 microg/ml, p = 0.045]. However, the logarithmic-transformed levels of residual adiponectin were not associated with intimal-medial thickness (p = 0.6398). CONCLUSIONS Hypoadiponectinemia adjusted for sex, age, body mass index implies the progression of carotid and coronary sclerosis.

Abstract
Catecholamines can overcome myocardial stunning. However, a previous report on energy metabolism in stunned myocardium during catecholamine infusion was based on the conventional biochemical methods which might affect contractile function. Twenty farm pigs were anesthetized and underwent 15 min coronary artery occlusion and 2 h reperfusion. Ten pigs were given 10 micrograms/kg/min dobutamine from immediately after and throughout the reperfusion (dobutamine group). The other ten pigs were given saline (control group). Phosphorus-31 magnetic resonance spectroscopy and sonomicrometry were done alternately. Dobutamine improved percent segment shortening after reperfusion (control/dobutamine = 3.8%-5.7%/11.7%-13.4%; P < 0.01). At 15 min ischemia, adenosine triphosphate (ATP) decreased (control/dobutamine = 72 +/- 8%/73 +/- 10%, n.s.), and remained depressed after reperfusion in both groups. After reperfusion, phosphocreatine (PCr) returned to and maintained the preischemic value in the dobutamine group, while in the control group, PCr overshoot (112 +/- 5%) was observed. Except for the presence and absence of PCr overshoot, there was no significant difference of ATP and PCr between the two groups, although rate pressure product was significantly higher in the dobutamine group than in the control group. Regional myocardial blood flow after reperfusion was significantly higher in the dobutamine group. Dobutamine may improve "stunning" through effective improvement of energy utilization and production, indicated by the disappearance of PCr overshoot and maintained ATP level.

Abstract
The in vivo protective effects of diltiazem, nifedipine, and verapamil on large and small coronary artery constriction induced by intracoronary injection of acetylcholine were compared by coronary arteriography in pigs. The percent narrowing of the epicardial major right coronary artery was used as an indicator of large coronary artery constriction, and the time required for contrast medium to reach the posterior descending coronary artery from the ostium of the right coronary artery was used as an indicator of small coronary artery constriction. Doses of 12.5, 25, 50, 100, and 200 micrograms of acetylcholine were administered into the right coronary artery under left ventricular pacing to keep the systemic hemodynamics constant. Marked prolongation of the flow time of contrast medium to greater than or equal to 8.1 s (control of less than or equal to 1.8 s) with mild narrowing of the epicardial major right coronary artery (less than or equal to 35%) was observed at doses of 12.5-50 micrograms of acetylcholine and was accompanied by myocardial ischemia. Over 50% narrowing of the epicardial major coronary artery plus markedly slow flow of contrast medium were induced in 12 of the 15 pigs by 100-200 micrograms of acetylcholine. Narrowing of the epicardial major coronary artery and the delay time of contrast medium flow induced by acetylcholine were both significantly reduced to 12-33% (control: 36-81%) and to 4.3-16.8 s (control: 16.2-37.7 s) after intracoronary injection of 100 micrograms of diltiazem.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Failure to Reduce Infarct Size by Intracoronary Infusion of Recombinant Human Superoxide Dismutase at Reperfusion in the Porcine Heart: Immunohistochemical and Histological Analysis. Journal of Molecular and Cellular Cardiology (1991) 23, 1287-1296. We quantitatively determined the extent of infarction and contraction band necrosis in porcine hearts, and analyzed the distribution of administered recombinant human superoxide dismutase (h-SOD) in the myocardium using a polyclonal antibody to h-SOD. After 1 hour of occlusion, h-SOD was infused for the first 30 min of reperfusion in SOD group, while pigs received only arterial blood in control group. The extent of infarction or contraction band necrosis was not significantly different between SOD group and control group. Positive staining by polyclonal antibody to h-SOD was detected only in the infarcted area in SOD group. Thus, h-SOD only entered irreversibly damaged myocytes and neither diminished reperfusion injury nor reduced infarct size in pigs.

Abstract
The time course of hypertrophy of surviving myocytes overlying the infarct after the onset was examined and the hypertrophy was analyzed in relation to the transmural extent of infarct in 34 autopsied hearts with Q wave infarction. The 34 hearts were divided into 4 groups according to the length of time between the onset of infarction and death. This was less than 5 days in group 1 (n = 10), 20-30 days in group 2 (n = 7), 40-60 days in group 3 (n = 7), and 12-24 months in group 4 (n = 10). To clarify the regional hypertrophy of myocytes overlying the infarct, the size of the surviving myocytes in the outer third of the left ventricular wall in the 1-cm wide central zone of the infarct was compared with that of the myocytes in the outer third of the left ventricular wall without infarction (control wall) in the same heart. To exclude factors which stimulate the hypertrophy of the whole left ventricle, the ratio of the monocyte diameter in the infarcted wall to that in the control wall was examined. It was 1.0 +/- 0.0 (mean +/- SD) in group 1, 1.0 +/- 0.1 in group 2, 1.2 +/- 0.1 in group 3, and 1.3 +/- 0.1 in group 4. The ratio was significantly higher in group 3 than in group 1 and 2, and was highest in group 4. In group 4, the corrected percentage transmural extent of infarct indicating the original transmural extent of infarct at the acute stage was 63 + 8%, and this transmural extent correlated positively with the ratio of myocyte diameter.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
To investigate the mechanism of cardiac dysfunction in myocarditis, myoglobin, an intracellular oxygen-transport, was immunohistochemically examined in biopsy specimens obtained from the right side of the ventricular septum and left ventricular free wall in 58 patients with myocarditis and 19 controls. Sections 4 microns thick were stained by the indirect immunoperoxidase method using a polyclonal antibody to human myoglobin as the primary antibody. Under light microscopy, the intensity of myoglobin immunoreactivity in the tissue section was semiquantitatively classified from grade 0 to grade 3. Then, the grade of myoglobin staining was compared with clinical, hemodynamic and histopathologic parameters. In right and left ventricular specimens, the grade of myoglobin staining was positively correlated with ejection fraction, but inversely with left ventricular end-diastolic and end-systolic volume indices. The percentage of myocytes with grade 0 was correlated with the number of mononuclear cells in the specimens. In addition, the grade of myoglobin staining in right ventricular specimens was positively correlated with the duration of illness but inversely correlated with the number of mononuclear cells. In 4 patients who had serial biopsies, the ejection fraction was improved and the grade of myoglobin staining was increased in the convalescent stage. These results indicate that myoglobin staining reflects the intensity of myocarditis and a decrease of myoglobin may be important as one of the pathogenetic factors of cardiac dysfunction in myocarditis.

Abstract
To investigate the ventricular expression of atrial natriuretic peptide (ANP) in human hypertrophic hearts, we conducted an immunohistochemical study of 130 endomyocardial biopsy specimens obtained from the right side of the ventricular septum (RVB), left ventricular free wall (LVB), or both from a total of 80 patients: 44 patients with hypertrophic cardiomyopathy (HCM), 14 with apical hypertrophic cardiomyopathy (APH), 13 with hypertensive hearts (HHD), and nine without hypertrophy (controls). No patients had apparent congestive heart failure. ANP was not seen in ventricular myocytes in controls but was identified in biopsy specimens of hypertrophic hearts, and its distribution was characteristic in each hypertrophic group: 15 RVB (37%) and two LVB (7%) of the HCM group, one RVB (7%) and two LVB (18%) of the APH group, and zero RVB (0%) and five LVB (46%) of the HHD group. Clinical data (including echocardiographic, hemodynamic, and angiographic data) were not directly related to ventricular ANP expression in HCM, APH, or HHD with one exception. In HHD patients, LVB specimens with ANP showed greater ventricular wall thickness than LVB specimens without ANP. According to histological data, however, the ANP-present RVB specimens of HCM or ANP-present LVB specimens of HHD had greater myocyte size than did the ANP-absent specimens. In addition, in HCM patients, the ANP-present RVB specimens showed more severe fibrosis and myofiber disarray than did the ANP-absent specimens. We conclude that a failing state and hemodynamic overload are not likely to be indispensable for ANP expression in human hypertrophic ventricles and that ventricular ANP expression occurs as a response to disease-specific changes: hemodynamic overload in HHD and histological changes such as myocardial fiber disarray, hypertrophy of myocytes, and fibrosis in HCM, which may reflect the characteristic distribution of intraventricular ANP.

Abstract
STUDY OBJECTIVE Protective effects of nipradilol, a newly synthesised vasodilating beta adrenoceptor antagonist, isosorbide dinitrate, and bunazosin on coronary artery constriction induced by intracoronary injection of acetylcholine were determined by coronary arteriography and compared in vivo in pigs. DESIGN Acetylcholine (12.5, 25, 50, 100 and 200 micrograms) was given into the right coronary artery under left ventricular pacing to maintain constant systemic haemodynamics. Percentage narrowing of the major epicardial coronary artery was used as an indicator of constriction of the large coronary arteries, and the time required for the contrast medium to reach the posterior descending coronary artery from the ostium of the right coronary artery (blood flow delay) was used as an indicator of constriction of the small coronary arteries. SUBJECTS 15 farm pigs weighing 80 to 90 kg were used. MEASUREMENTS AND MAIN RESULTS A marked blood flow delay of over 7.0 s (control: less than or equal to 1.8 s) with less than 34% narrowing of the epicardial major coronary artery was observed in 13 of 15 pigs with 12.5-50 micrograms of acetylcholine, and in the other two pigs with 100 micrograms of acetylcholine. When marked blood flow delay occurred, the perfused right ventricular myocardium became macroscopically anaemic (ischaemic). Over 75% narrowing of the major epicardial coronary artery was induced in six of the 15 pigs, and over 50% narrowing in 12, with marked blood flow delay with 100 to 200 micrograms of acetylcholine. However, after intracoronary infusion of 10 micrograms of nipradilol, acetylcholine induced narrowing in the epicardial major coronary artery was significantly reduced from 44-79% in control to 19-37% despite 200 micrograms of acetylcholine, though the time delay in coronary blood flow did not change significantly. By pretreatment with intracoronary isosorbide dinitrate (2.5 mg), the percent narrowing of the large coronary artery and the time delay in coronary blood flow were significantly reduced (narrowing from 32-84% to 10-27%; time delay from 7.6-41.6 s to 2.7-22.7 s). Pretreatment with intracoronary bunazosin, an alpha 1 adrenoceptor antagonist (100 micrograms), showed no protective effect on narrowing of the epicardial major coronary artery or blood flow delay. CONCLUSIONS Isosorbide dinitrate prevents coronary artery constriction induced by acetylcholine in swine. Nipradilol prevents large, but not small, coronary artery constriction, probably through a direct nitrate like vasodilating action.

Abstract
The expression of atrial natriuretic polypeptide (ANP) in the ventricles of human hearts with myocardial infarction (MI) was studied immunohistochemically. Immunoreactive myocytes were identified in the ventricular tissues of all of 16 hearts with old MI (both with and without heart failure) and in all five hearts with subacute MI, but not in any of the eight hearts without MI nor in the five with acute MI. In the nonfailing hearts with MI, ANP positive myocytes surrounded the areas of infarction, and were also seen in the subendocardium of the infarcted segment. In the failing hearts with MI, ANP expression was noted in the whole ventricular subendocardial region, in addition to the border of infarcts. The sites of ANP expression corresponded well to those of marked stress attributable to tissue shrinkage or fibrosis due to MI, haemodynamic overload, or both. It thus appears that ANP expression is augmented in human hearts with MI regardless of the presence or absence of heart failure, and it is suggested that regional mechanical stress on the ventricular myocardium, as well as haemodynamic overload, may be very closely associated with ventricular ANP expression.

Abstract
We report a case of left atrial myxoma found when examination was made for the cause of orthostatic hypotension. The case was that of a man of 61 years of age. For the previous 2 years, the man had felt dizzy only at the standing or sitting position. The blood pressure was 90/50 at recumbency and 64/40 at the sitting position. Echocardiographic study revealed a left atrial tumor, which fell into the left ventricular cavity and prevented the blood from filling the left ventricular cavity. This effect was more severe at the sitting position than at recumbency. Resection of the tumor was carried out. It was a myxoma with a diameter of 3.5 cm with a stalk adhering to the postero-inferior wall of the left atrium. After the removal of the tumor, the patient's complaint and orthostatic hypotension disappeared; blood pressure was 102/60 at recumbency and 98/64 at sitting position. Orthostatic dizziness has been reported in some cases as one of the symptoms of the intracardiac tumor. But the state of aggravation at the sitting position has never been observed during actual echocardiographic study. The myxoma adhered to the postero-inferior wall of the left atrium, which site might be associated with the symptom (orthostatic hypotension).

Abstract
In order to clarify the pathogenesis of acute myocardial infarction (MI) in hearts with normal coronary arteries, infarct size, and the extent of contraction band necrosis (CBN), coagulation necrosis, and hemorrhage were quantitatively examined using an image analyzer in 5 autopsy cases of MI with normal or nearly normal extracardiac coronary arteries. One patient died 40 h after acute MI. A second patient with acute MI due to severe spasm of segment 6, confirmed by cineangiography, died three days later. The third patient had already suffered a subarachnoid hemorrhage, and died 10 h after the onset of acute MI. The fourth patient had aortic stenosis and regurgitation. She developed acute MI due to total occlusion of segment 6, confirmed by cineangiography 4 h after the onset, and died 61 days later. Autopsy revealed old anteroseptal MI with normal coronary arteries and valvular thrombi. The fifth patient had a malignancy, and died one day after the onset of acute MI. Autopsy revealed multiple occlusive thrombi in the small intramural coronary arteries of the left ventricular wall supplied by segment 14, without any stenosis in the feeding vessel. Most infarcts were localized in the territory supplied by 1 or 2 of the 3 epicardial coronary arteries, and coincided with the clinically diagnosed infarct site. The infarct size ranged from 3%-26% of the left ventricular wall, and infarcts were generally localized to the inner third of the wall (67 +/- 20%). Histological examination of the four patients with acute MI revealed diffuse CBN (86 +/- 14% of the infarcted area) and/or hemorrhage.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
To define whether recanalization after occlusion can reduce the myocardial infarct size, we compared the infarct size in 25 pig hearts without collateral circulation, 35 dog hearts with collateral circulation and 11 human autopsied hearts with coronary thrombolysis at 2 to 6 hours after the onset of acute myocardial infarction. The data showed that % infarct size in the risk area increased according to the duration of occlusion. In the pig, % infarct size was 80 +/- 9% in the recanalization after 1 hour occlusion and 96 +/- 2% in the recanalization after 2 hour occlusion. There was no significant difference between these and the permanent occlusion group (95 +/- 3%). In the dog, % infarct size was 35 +/- 31% in the recanalization after 4 hour occlusion and 59 +/- 27% in the permanent occlusion group. In human autopsied hearts, the infarct size was the same between the recanalization group (82 +/- 6%) and the permanent occlusion group (80 +/- 11%). The % infarct size in the recanalization groups was less than or the same as that in the hearts with permanent occlusion in dog, pig and human. Thus, it is concluded that, to reduce conclusively the infarct size, recanalization should be done within 1 hour after the occlusion in the hearts without collateral circulation and within 4 hours in the hearts with collateral circulation. So called reperfusion injury which means the greater expansion of the % infarct size than that in the permanent occlusion is not present.

Abstract
The presence of atrial natriuretic polypeptide (ANP) was immunohistochemically demonstrated in the formalin-fixed and paraffin-embedded tissues of 25 autopsied normal human hearts using monoclonal antibody. The ANP amounts were immunohistochemically semiquantified and compared with amounts measured by radioimmunoassay (RIA). The 25 autopsied hearts were divided into 5 groups according to the interval of formalin fixation or the length of time between death and fixation. Formalin-fixation intervals were one week in group 1A and 1B; 1 year in group 2; 4 to 5 years in group 3 and 10 to 12 years in group 4. The hearts of group 1A, 2, 3 and 4 were fixed within 5 hours after death. Those of group 1B were fixed 14 to 18 hours at 4 degrees C. After fixation, the left and right atrial appendages (LAA and RAA), the left and right atrial free walls (LA and RA), the left and right ventricular free walls (LV and RV) and the ventricular septum (VS) were transmurally dissected from each heart. They were embedded in paraffin, cut into 4 microns sections and immunohistochemically stained by the avidin-biotin-peroxidase complex (ABC) method using monoclonal antibody against alpha-human ANP. Under a light microscope, they were evaluated semiquantitatively according to the incidence of ANP-positive cells and the intensity of immunostaining. For every heart in group 1A, the tissue concentrations of ANP in the different parts were also measured separately by RIA before fixation. ANP-positive myocytes were noted in the atria of all hearts of all groups, but no in any ventricular myocytes. Both their incidence and grade in the atria were similar among groups 1A, 1B and 2. However, they were less in group 3, and least in group 4 among all groups. For all groups, they decreased in the following order: LAA greater than RAA not equal to LA greater than RA; the inner 1/3 greater than the middle 1/3 greater than the outer 1/3 of the atrial walls. The order in LAA, RAA, LA and RA.(ABSTRACT TRUNCATED AT 250 WORDS)
