A 46-year-old woman complained of a 10-year history of headache, nausea, a precordial oppressive feeling and shortness of breath on miction. She had noted a marked elevation in her blood pressure after miction using home blood pressure measurement. Her catecholamine levels were less than twice the value of the normal upper limit.

Aims: Consensus-derived guidelines recommend renal stenting for patients with atherosclerotic renal artery disease (ARAD) and heart failure (HF). The aim of this prospective multi-centre observational study was to verify our hypothesis that changes in E/e', an echocardiographic correlate of left ventricular (LV) filling pressure, following renal stenting may differ between ARAD patients with and without HF.

Methods And Results: This study enrolled de novo ARAD patients undergoing renal stenting at 14 institutions.

Aim: The aim of the present study was to evaluate the natural course of acute incomplete stent apposition (ISA) after second-generation everolimus-eluting stent (EES) when compared with first-generation sirolimus-eluting stent (SES) by using optical coherence tomography (OCT).

Methods And Results: From the OCT substudy of the RESET trial, we identified 77 patients (EES = 38 and SES = 39) who successfully underwent serial OCT examination at post-stenting and 8-12-month follow-up. The presence of ISA was assessed in the OCT images, and ISA distance was measured from the centre of the strut blooming to the adjacent lumen border.

Background: The aim of this study was to evaluate the diagnostic potential of coronary flow velocity reserve (CFR) measurement by transthoracic Doppler echocardiography (TTDE) to detect restenosis in the 3 major coronary arteries: the left anterior descending coronary artery, right coronary artery, and left circumflex coronary artery.

Methods: The lesions of 175 patients who were scheduled for follow-up coronary angiography and TTDE 6 months after undergoing stents implantation were studied. CFR was assessed by TTDE in the targeted arteries into which stents had been implanted.

Objectives: The aim of this study was to clarify whether pioglitazone suppresses in-stent neointimal proliferation and reduces restenosis and target lesion revascularization (TLR) after percutaneous coronary intervention (PCI).

Background: Previous single-center studies have demonstrated the anti-restenotic effect of a peroxisome proliferator-activated receptor gamma agonist, pioglitazone, after PCI.

Methods: A total of 97 patients with type 2 diabetes mellitus (T2DM) undergoing PCI (bare-metal stents only) were enrolled.

Left ventricular (LV) ejection fraction (EF) was known as a conventional predictor of heart failure (HF). However, early transmitral flow velocity (E)/early diastolic velocity of mitral annulus (E') correlated well with LV end-diastolic pressure, and E/E' ratio >15 was an excellent predictor of adverse outcomes in patients with HF. This study was designed to determine the prognostic value of a new combined index, E/E' ratio and LVEF, in patients with HF.

A 76-year-old woman was admitted to our hospital because of exertional dyspnea and leg edema during the previous month. Her systolic blood pressure on admission was 80 mmHg with 12 mmHg of pulsus paradoxous, and her pulse rate was 110 beats/min. Chest radiography revealed marked cardiomegaly and echocardiography showed massive pericardial effusion mainly behind the left ventricle and collapse of the right ventricle.

Objective: This study was performed to determine the potential efficacy of an automated device with a load-distributing band (AutoPulse, Revivant Corporation), in improving neurologically intact survival after cardiac arrest.

Design: Randomized, controlled trial.

Setting: University animal laboratory.

Coronary flow reserve was evaluated using transthoracic Doppler echocardiography before and after 3 months of fluvastatin therapy in patients with hypercholesterolemia. Coronary flow reserve increased significantly after lipid-lowering therapy, and coronary microcirculation was improved in patients with hypercholesterolemia.

Two cases of dilated cardiomyopathy with intraventricular conduction delay, or left bundle-branch block and refractory heart failure, were markedly improved by biventricular pacing. The first patient's condition (Case 1) could not be improved despite administration of intravenous inotropic agents. He required mechanical ventilation and continuous hemodialysis as his condition worsened.
