    Background: A previous study reported that amlodipine retarded coronary plaque progression in patients with coronary artery disease. The goal of this multicenter study was to determine which calcium-channel blockers (CCBs) other than amlodipine attenuated the progression of plaque volume (PV) accessed by intravascular ultrasound (IVUS). Methods and Results: ALPS-J was a prospective, randomized open-label study conducted at 5 centers. Patients who had hypertension and were scheduled for coronary intervention were enrolled. Subjects were randomly assigned to receive 16 mg/day of azelnidipine or 5 mg/day of amlodipine administered for 48 weeks. The primary endpoint was the percent change in coronary PV measured by IVUS. Between 2007 and 2009, 199 patients were enrolled; 115 had evaluable IVUS images at both baseline and after 48 weeks of treatment. Blood pressure significantly reduced to 128/68 mmHg at follow-up. The lipid profiles in the 2 groups were comparable (low-density lipoprotein cholesterol: 97 mg/di). The %change in PV showed a significant regression of -4.67 and -4.85% in the azelnidipine and amlodipine groups, respectively. The upper limit of the 95% confidence interval of the mean difference in %change PV between the 2 groups (0.18%, 95% confidence interval -4.62 to 4.98%) did not exceed the pre-defined non-inferiority margin of 6.525%. Conclusions: ALPS-J demonstrated that azelnidipine was not inferior to amlodipine for primary efficacy. In addition to standard medical therapy, dihydropyridine CCBs will retard PV progression in hypertensive patients. (Circ J 2011;75: 1071-1079)

    Background: A large clinical trial clarified that pioglitazone reduces cardiovascular events in diabetic patients. However, effects of pioglitazone on structure of coronary atherosclerotic plaques have not been demonstrated. We examined whether pioglitazone reduces volumes of coronary atherosclerotic plaques using intravascular ultrasound (IVUS). Methods: Twenty-six consecutive patients with type 2 diabetes mellitus (DM) or impaired glucose tolerance (IGT) undergoing percutaneous coronary intervention (PCI) were enrolled. Echolucent plaques without significant stenosis were selected in IVUS video images at non-PCI-influenced coronary segments and volumetric analysis of the targeted plaques was performed. The patients were randomly assigned into 2 groups: pioglitazone group consisted of 13 patients taking pioglitazone 15 mg/day for initial 14 days after PCI and subsequent 30 mg/day during 6-month follow-up, and control group with 13 patients as control. The plaque volumes and some parameters such as plasma lipid profiles and high-sensitive C-reacting protein (hs-CRP) levels were compared between baseline and the follow-up in those groups. Results: In the pioglitazone group after 6 months, the plaque volume was significantly reduced (101.3 +/- 32.1 to 94.6 +/- 33.6 mm(3), -7.2%; p=0.0023), plasma triglyceride was significantly decreased (-14.9%) and high density lipoprotein cholesterol was substantially increased (+20.0%) without any significant change in low density lipoprotein cholesterol (LDL-C). Also, hs-CRP level tended to be decreased. However, no significant change in plaque volumes and those parameters was observed in the control group. Conclusions: Pioglitazone may induce regression of coronary atherosclerotic plaques without LDL-C reduction in patients with DM and IGT. (C) 2008 Elsevier Ireland Ltd. All rights reserved.

    Background: This study examined feasibility and safety of granulocyte colony- stimulating factor ( G- CSF) treatment for patients with acute myocardial infarction ( AMI). Methods: Forty patients with AMI related with the left anterior descending coronary artery, who underwent successful percutaneous coronary intervention ( PCI), were randomized into G- CSF group ( n= 18) or Control group ( n= 22). G- CSF treatment was started within 24 h after PCI. Tc-99m- tetrofosmin single- photon emission computed tomography ( SPECT) was performed at 4 days and 6 months after AMI. SPECT data was analyzed for LV end- diastolic volume ( LVEDV), LV end- systolic volume ( LVESV), LV ejection fraction ( LVEF) and myocardial perfusion. Results: LVEF at 6 months was significantly better than that at 4 days in G- CSF group ( p= 0.013), but not changed in Control group ( p= 0.245). Although no significant difference was observed for LVEDV between the two groups, LVESV tended to be decreased only in G-CSF group. In G- CSF group, defect score ( DS) was significantly decreased from 4 days to 6 months after AMI. Restenosis rate at 6 months after AMI was not significantly different between the two groups. Conclusions: G- CSF treatment for patients with AMI was effective and did not have any clinical and angiographic adverse effects. (C) 2006 Elsevier Ireland Ltd. All rights reserved.

    We describe a novel therapy of mononuclear cell transplantation combined with a left ventricular assist device (LVAD) for severe ischemic heart failure. Significant myocardial recovery by the LVAD rarely occurs in the severely failing heart. We undertook successful mononuclear cell transplantation in a patient who sustained an acute myocardial infarction that had resulted in the LVAD therapy. The heart regained good function after cell transplantation, and the LVAD was explanted 6 weeks later. These results suggest that this novel therapy could be an alternative to cardiac transplantation for severe ischemic heart failure.

    Circulation Journal 70(5) 548-552 2006年
    Background: Despite an increase in the frequency of coronary angiography (CAG) in Japan, the exact incidence of contrast-induced nephropathy (CIN) remains unknown in the Japanese population, especially in patients with chronic renal insufficiency. In addition, the nature of pharmacological interventions that would benefit the patients before or after procedures such as coronary bypass graft (CABG) and percutaneous coronary intervention (PCI) has not been fully investigated. Methods: In the trial 500 patients with renal insufficiency (defined as a glomerular filtration rate (GFR) of between 89 and 30 ml·min-1·(1.73 m-2) following CAG will be randomly assigned to receive either valsartan, an angiotensin receptor blocker or angiotensin converting enzyme (ACE) inhibitor plus valsartan.1 The primary end-point is a change in the GFR of patients, which will be followed up for 3 years, including following CABG surgery or PCI. The incidence of cardiac events as well as the adverse effects of pharmacological intervention will be evaluated. In addition, the incidence of renal artery stenosis at the time of CAG will be reported also however, the patients with renal artery stenosis will be excluded from the present study. Conclusion: The present study will provide data on: 1) the exact incidence and course of renal function of CIN after CAG and 2) the comparative therapeutic benefit of pharmacological intervention with valsartan alone or with valsartan and an ACE inhibitor in combination in patients with coexisting coronary artery diseases and chronic renal insufficiency, regardless of whether they receive CABG or PCI. In addition to these studies, an estimate of the incidence of renal artery stenosis in these patients will be demonstrated.

    Background Plaque stabilization by statins is important for reduction of cardiovascular events but has not been demonstrated enough in vivo. We examined whether statins clinically alter the structure of coronary atherosclerotic plaques using intravascular ultrasound (IVUS) radio-frequency (RF) signal analysis. Methods Fifty consecutive patients undergoing percutaneous coronary intervention were enrolled. Intravascular ultrasound radio-frequency signals were acquired from non-percutaneous coronary intervention-targeted echolucent plaques. The patients were randomly assigned into 2 groups: group S in = 25) taking atorvastatin 10 mg/d and group C (n = 25) as control. After 6-month follow-up, IVUS-RF signals were sampled at the some plaque sites. Several regions of interest were placed on each plaque. Intravascular ultrasound radio-frequency parameters were blindly calculated in all regions of interests (group 5, n = 148; group C, n = 191). Targeted plaque volumes were also measured. Those data were compared between baseline and follow-up. Results in group S after 6 months, plasma low-density lipoprotein level was significantly decreased (133 13 to 87 29 mg/dL, P <.0001), integrated backscatter of IVUS-RF signals was substantially increased (-53.8 +/- 4.5 to -51.2 +/- 4 9 dB, P <.0001), and plaque volume was significantly reduced, whereas no change was demonstrated in group C. Conclusions These results suggest that statins alter properties as well as volumes of coronary plaques within 6 months, which may be related to plasma low-density lipoprotein reduction. Intravascular ultrasound radio-frequency signal analysis may be useful to evaluate the effects of drugs on stabilization of coronary atherosclerotic plaques.

    Background: In both cardiac and hepatic disorders it is desirable to accurately visualize the direction and scale of blood flow in the whole organ in pulsating 3-dimensional (D) images, which are known as 4-D images. Methods and Results: The present study used 256-slice cone-beam computed tomography (CT) (Athena, Sony-Toshiba) at one rotation per second and a section thickness of 0.5 mm to show the dynamics of cardiovascular circulation and hepatic perfusion by contrast injection in 4-D films of pigs. Four pigs (20 kg each) were anesthetized with isoflurane. The distal tips of the catheters were positioned in the inferior vena cava (IVC) (pigs 1-3) and in the proper hepatic artery (pig 4). Volumetric scanning and injection of contrast material were started simultaneously and continued for 25 s with image reconstruction at 1-s intervals. In pigs 1-3, 4-D filming revealed the dynamics of cardiovascular circulation, first in the IVC, followed by the right ventricle and pulmonary artery, then the left ventricle, left atrium, pulmonary vein, and finally, the right heart disappeared and only the left heart and aorta remained visible. In pig 4, the hepatic arterial trees, followed by the venous trees, could be easily visualized in turn on the 4-D images. Conclusions: This technology successfully demonstrated cardiovascular circulation and hepatic perfusion in 4-D and will have clinical applicability.

    Background: New equipment, the Cardiac Reader™, which can measure blood concentrations of troponin T (T) and myoglobin (M) in only 15 min at the bedside was evaluated for early diagnosis of acute myocardial infarction (AMI). Methods and Results: A total of 34 consecutive patients with AMI who came to hospital within 24 h after onset were studied. Blood samples were collected from the patients at admission and 6, 12, 24, 48 h after onset to qualitatively and quantitatively measure T, M and creatine kinase-MB fraction. There were 20 patients with positive results by qualitative troponin T test and 29 with positive results by quantitative test. Of the patients who visited hospital within 3 h of onset, 17% were positive by the qualitative test and 67% cases had positive results in the quantitative test. The patients were divided into 2 groups according to the flow grade in the infarct-related coronary artery. In the TIMI 0-1 group (n=28), serum myoglobin concentrations were higher than in the TIMI 3-4 group (n=6) at admission and at their peak. Conclusion: The rapid quantitative test of T and M is useful for early diagnosis of AMI and as an indicator of its severity, which can be evaluated from the myoglobin concentration in the hyper-acute phase.

    Churg-Strauss syndrome is characterized by asthma, eosinophilia and systemic necrotizing vasculitis cardiac involvement (ie, eosinophilic heart disease) is the major cause of morbidity and mortality, although there are no reports of an association between left ventricular dysfunction because of eosinophilic heart disease and myocardial blood flow or myocardial fatty acid metabolism. A patient presented with Churg-Strauss syndrome associated with eosinophilic heart disease that had progressed to dilated cardiomyopathy. Coronary angiography, thallium-201 (201T1) and iodine-123 β-methyl-iodophenyl pentadecanoic acid (123I BMIPP) myocardial single photon emission computed tomography (SPECT) were performed to evaluate left ventricular dysfunction. Although coronary angiography was normal and 201T1 SPECT showed no apparent image defect, 123I BMIPP SPECT showed diffuse decreased accumulation, excepting the apex. The left ventricular dysfunction in patients with eosinophilic heart disease is associated with impaired myocardial fatty acid metabolism rather than with impaired myocardial blood flow.

  • Comparison of the effects of beta blockers and calcium antagonists on cardiovascular events after acute myocardial infarction in Japanese subjects
    H Yasue, H Ogawa, H Kawano
    AMERICAN JOURNAL OF CARDIOLOGY 93(8) 969-973 2004年04月
    The efficacy of beta blockers in managing patients with post-acute myocardial infarction (AMI) was established based on randomized controlled trials predating the era of modern therapy in Western populations. We compared the effects of 6 blockers on cardiovascular events with those of calcium antagonists in Japanese post-AMI patients on modern reperfusion therapy by performing a multicenter, prospective, randomized, open-blind end point study. Five hundred forty-five patients were assigned to the p-blocker group and 545 patients to the calcium antagonist group. The mean follow-up period was 455 days. There was no significant difference in the incidence of cardiovascular death (0.7% vs 1.1%), reinfarction (0.9% vs 1.3%), uncontrolled unstable angina (11.0% vs 10.6%), and nonfatal stroke (0.7% vs 0.2%) between the 2 groups. However, the incidences of heart failure and coronary spasm were significantly higher in the beta-blocker group than in the calcium antagonist group (4.2% vs 1.1%, p = 0.001; 1.2% vs 0.2%, p = 0.027, respectively). We conclude that the cardiovascular event rate is substantially lower in Japanese post-AMI patients receiving modern therapy than in those reported in the West, and that there are no significant differences in the cardiovascular event rate between the p-blocker and calcium antagonist groups.

    Circulation Journal 68(3) 192-197 2004年03月
    Background: It has been reported that both nicorandil and magnesium have a cardioprotective effect in experimental ischemia-reperfusion models. In the present study, the cardioprotective effects of nicorandil and magnesium as an adjunct to reperfusion therapy in patients with acute myocardial infarction (AMI) were compared. Methods and Results: Forty consecutive patients with AMI caused by occlusion of anterior descending coronary artery were randomized into 3 groups: (1) Group N: nicorandil was given as 4mg iv and 4mg ic before reperfusion, followed by continuous infusion at 4mg/h for 24h (2) Group M: magnesium was administered at 10 mmol iv before reperfusion, followed by continuous infusion at 0.4 mmol/h for 24 h and (3) Group C: neither nicorandil nor magnesium was given. Left ventriculography was performed immediately after reperfusion and 3 months later. There was no significant change in regional wall motion (RWM) in either Group C or M, whereas that of group N improved significantly. The change in RWM in Group N was significantly greater than in Group C (Group N: 0.92±0.92, Group M: 0.44±0.80, Group C: -0.01±0.65, p< 0.05). Conclusions: The early administration of nicorandil as an adjunct to reperfusion is useful for cardioprotection in AMI, but magnesium is not.

    冠動脈の動脈硬化の進展と各種動脈硬化促進因子の血清濃度との関係を調べ,第一にトロンボモデュリン(TM)が,冠動脈硬化の進展に比例して上昇するのではなく,内皮機能障害が進むことでTM産生能も低下する仮説を調べた。第二に,TM,VCAM-1,ホモシステイン(HC),TNF-αが相互に作用しあっている可能性の傍証として各種分子の血清濃度の相関関係を検討した。経皮経管冠動脈形成術(PTCA)を施行した48例(男性36例,女性12例,平均年齢59±8歳)に対し,空腹時の動脈血採血をヘパリン注射前に行った。冠動脈硬化の進展の指標として,1)病変枝数,2)Gensiniscore,および3)Coronary extent scoreを用いた。病変枝数で群分けした場合では,いずれの物質の血清濃度も群間で有意差は認められなかった。Gensini scoreが40未満の群と40以上の群で分けた場合では,Gensini scoreが40以上の群でHbAlcは有意に高く,TMは有意に低かった。Coronary extent score(狭窄箇所数)が1箇所の群と,2〜4箇所の群および5箇所以上の群で分けた場合では,群間有意差を認めた物質はTMのみであり,狭窄箇所数の増加に連れて血清濃度が低下する傾向にあった。また,TM,VCAM-1,HC,TNF-αの間には,互いに強い相関が認められた。この結果の説明として,病変の進展とともに血管内皮機能が障害されてTM産生が低下したと考えられる。また,HCとTMの間の強い相関は,HCが血管内皮細胞にダメージを与えてTMの遊離や発現を促している可能性を示唆している。同様に,HCがVCAM-1の発現に関与している可能性や,TNF-αが血管内皮細胞におけるTMの発現を促している可能性が考えられた。
