Background Phase contrast ( PC ) cine‐magnetic resonance imaging MRI of the coronary sinus allows for noninvasive evaluation flow reserve CFR ), which is an index left ventricular microvascular function. The objective this study was to investigate in patients with heart failure preserved ejection fraction HF p EF ). Methods and Results We studied 25 (mean SD age: 73±7 years), 13 hypertensive hypertrophy LVH (67±10 18 controls (65±15 years). Breath‐hold cine‐ images were obtained assess blood...
In non-ST-segment elevation acute coronary syndromes (NSTE-ACS), the relation of level high-sensitivity C-reactive protein (CRP) to progression atherosclerosis remains unclear.The study group comprised 153 patients with NSTE-ACS who underwent percutaneous interventions (PCI) and follow-up (mean interval, 7 months) angiography. Rapid was defined as > or =10% diameter reduction a preexisting stenosis =50%, =30% <50%, development new in previously normal segment, any total occlusion....
Background: Few studies have examined whether high-responsiveness to antiplatelet therapy is associated with an increased risk of bleeding in patients receiving dual therapy. MethodsandResults: Elective drug-eluting stent implantation was performed 184 treated aspirin and a thienopyridine (200 mg/day ticlopidine or 75 clopidogrel). The subjects were divided into 3 groups according post-treatment platelet reactivity before stenting as measured by the response adenosine diphosphate: 1st...
Background:Although rapid progression (RP) of coronary artery disease (CAD) has been shown to be a powerful predictor cardiovascular events, predictors RP are not fully understood in patients with acute syndrome (ACS).Methods and Results:We prospectively investigated the clinical impact glycemic variability (GV), as determined on continuous glucose monitoring system (CGMS), non-culprit lesions 88 ACS. was defined ≥10% diameter reduction pre-existing stenosis ≥50%; ≥30% <50%; development new...
Cardiovascular magnetic resonance (CMR) provides non-invasive and more accurate assessment of right ventricular (RV) function in comparison to echocardiography. Recent study demonstrated that RV by echocardiography was an independent predictor for mortality patients with interstitial lung disease (ILD). The purpose this determine the prognostic significance CMR derived ejection fraction (RVEF) ILD patients. We enrolled 76 24 controls current study. By using 1.5 T scanner equipped 32 channel...
(1) Background: The probability of technical success in percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) represents essential information specifying the priority PCI treatment selection patients with CTO. However, predictabilities existing scores based on conventional regression analysis remain modest, leaving room improvements model discrimination. Recently, machine learning (ML) techniques have emerged as highly effective methods prediction and decision-making...
Long-term intake of long-chain n-3 polyunsaturated fatty acids (n-3 PUFAs), especially eicosapentaenoic acid (EPA) is associated with a low risk for cardiovascular disease. Phase-contrast cine magnetic resonance (PC CMR) can assess coronary flow reserve (CFR). The present study investigates the relationship between CFR evaluated by PC CMR and serum EPA.
Background Among patients treated with percutaneous coronary intervention for chronic total occlusion ( CTO ‐ PCI ), on long‐term hemodialysis are at significantly high risk cardiovascular mortality and morbidity. However, clinical or angiographic predictors that might aid in better patient selection remain unclear. We aimed to assess the acute impact of who underwent . Methods Results The Retrograde Summit registry is a multicenter, prospective undergoing 65 Japanese centers. Patient...
Background In patients with acute myocardial infarction (AMI), the relationship of serial changes in ST-segment elevation after reperfusion to left ventricular (LV) function remains unclear. Methods and Results The study group comprised 164 reperfused anterior AMI within 6 h symptom onset. sum deviation was calculated on admission (ΣST-admission), 1 (ΣST-1 h) 24 (ΣST-24 reperfusion. ST resolution defined as a reduction ΣST-1 ≥50% compared ΣST-admission. Patients were classified into 3...
The differential diagnosis between precapillary and postcapillary pulmonary hypertension (PH) is important for deciding on the appropriate therapeutic strategy. aim of this study was to assess whether atrial volume ratio can differentiate post-capillary PH.Seventy-seven patients with PH who underwent transthoracic echocardiography (TTE) right heart catheterization were retrospectively studied. Pulmonary defined as a mean arterial pressure 25 mm Hg or higher by catheterization. Patients...
Percutaneous coronary intervention (PCI) is widely used in patients with chronic total occlusion (CTO), but its benefit improving long-term outcomes controversial. We aimed to develop a prediction score for grading "survival advantage" conferred by successful results of CTO-PCI and scoring system the influence on major adverse cardiac cerebrovascular events (MACCEs). Follow-up data 2625 who underwent at 65 Japanese centers were analyzed. An integer was developed including statistical effect...
A case of double aortic arch that was well visualized using transthoracic echocardiography is reported. 38‐year‐old man underwent for the evaluation dyspnea. suprasternal view showed ascending aorta bifurcate to left and right arches, with blood flow from bilateral arches. The diagnosis side–dominant made, patient's symptom conceivably related compression trachea due a vascular ring. This report indicates potential usefulness noninvasive detection in adults.
A 62-year-old male was transferred to our hospital complaining of palpitations. His heart rate 185/min. Electrocardiogram showed a narrow QRS regular tachycardia and the changed spontaneously another with two alternating cycle lengths. The arrhythmia stopped by administration adenosine triphosphate. Findings from electrophysiological study suggested that there an accessory pathway (AP) dual atrioventricular (AV) nodal pathways. After AP ablation, any other tachyarrythmias were not induced....
Background: As percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) gains wider acceptance as a therapeutic option artery disease, the importance of appropriate patient selection has increased. Although cardiovascular magnetic resonance imaging (MRI) allows segmental and quantitative analyses myocardial ischemia scar transmurality, it limitations, including contraindications, cost, accessibility. This study established non-invasive method to evaluate patients undergoing...
Objective: Elevated pulse pressure (PP) is a well recognized predictor of adverse outcome in elderly hypertensive subjects whereas its clinical significance young individuals remains controversial.The aim the present study was to investigate elevated PP young-to-middle-age screened for stage 1 hypertension.Methods: We examined 1241 18-to-45-year-old participants from HARVEST study.The predictive role versus mean blood (MBP) incident hypertension and cardiovascular events (CVE) evaluated Cox...
