In patients with heart failure and atrial fibrillation, the AF-CHF (Atrial Fibrillation and Congestive Heart Failure) trial did not demonstrate the superiority of rhythm control (RhyC) over a rate control (RaC) strategy on cardiovascular mortality. Nevertheless, deleterious hemodynamic effects of atrial fibrillation can lead to further decrease in left ventricular (LV) function and progression of symptoms. This echocardiographic sub-study was designed to compare the effects of the two treatment strategies o...
Structure and function of the ascending aorta in palliated transposition of the great arteries.
In transposition of the great arteries (TGA), the right ventricle (RV) is subaortic and abnormal aortic structure or function could adversely affect the capacity of the RV to supply the systemic circulation. Our aim was to assess aortic dimensions and distensibility and RV function in patients with palliated TGA using cardiovascular magnetic resonance imaging (CMR).
Health status of cardiac genetic disease patients and their at-risk relatives.
Health status is an important outcome measure that incorporates multiple dimensions of health, including symptoms, functional status, and psychosocial factors. While health status has been shown to be a predictor for hospital readmission, morbidity and mortality in the heart failure setting, there are limited data in cardiac genetic disease. We examined health status in a number of cardiac genetic disease groups compared to the general Australian population.
Chronic thromboembolic pulmonary hypertension (CTEPH) has been considered to be caused by single or recurrent pulmonary embolism (PE) arising from deep vein thrombosis (DVT). In Japan, female predominance and association of HLA-B*5201 with CTEPH unrelated to DVT were reported. In acute PE residual proximal DVT is associated with larger obstruction of pulmonary arteries. However, it remains uncertain whether DVT and the type of DVT are associated with clinical phenotype of CTEPH.
We investigated whether an additional intracoronary tirofiban bolus administration following upstream intravenous treatment could further improve myocardial reperfusion and clinical outcome in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI).
Refinement of echocardiographic criteria for left ventricular noncompaction.
Left ventricular hypertrabeculation/noncompaction (LVNC) is a cardiac abnormality whose echocardiographic criteria are still controversial. Cooperation between echocardiographic laboratories may contribute to uniformly accepted criteria, as illustrated by the following pilot study.
Low pulmonary vascular compliance predisposes post-Fontan patients to protein-losing enteropathy.
Protein-losing enteropathy (PLE) is a life-threatening and poorly understood complication after the Fontan operation. We sought to determine the pre-operative risk factors for PLE which developed after the extracardiac conduit Fontan operation.
Cardiac fibrosis and vascular remodeling are attenuated by metformin in obese rats.
Human obesity has been associated with alterations of vascular structure, especially in large and medium arteries, but the effects of insulin-sensitizers are not well known.
Pulmonary vascular remodeling with idiopathic pulmonary arterial hypertension (IPAH) is associated with impaired apoptosis of pulmonary artery smooth muscle cells (PASMCs). We have reported that high-dose prostaglandin I2 (PGI2) therapy markedly improved hemodynamics in IPAH patients. The therapy is thought to reverse vascular remodeling, though the mechanism is unclear. The aim of this study is to assess proapoptotic effects of PGI2 on PASMCs obtained from IPAH patients.
Previous echocardiographic studies using tissue Doppler imaging (TDI) and speckle tracking imaging (STI) have demonstrated that obstructive sleep apnea syndrome (OSAS) patients may develop subclinical left ventricular (LV) systolic and diastolic dysfunction. Our purpose was to evaluate the impact of OSAS on LV torsion dynamics and aortic stiffness by using TDI and STI echocardiography.
Pathologically, the lesions responsible for acute coronary syndrome (ACS) are ruptures of vulnerable plaques (and occasionally fibrous-cap erosions or calcified nodules) with a superimposed thrombosis. We aimed to clarify the clinical presentations related to the morphologies of coronary lesions of ACS using intravascular ultrasound (IVUS) and optical coherence tomography (OCT).
Cardiovascular diseases (CVDs) have a high prevalence in developing and developed countries and myocardial infarction accounts for majority of deaths and disabilities. The current study dealt with the protective role of Amaranthus viridis Linn on isoproterenol (ISO)-induced myocardial infarction (MI) in rats.
To evaluate the safety and feasibility of percutaneous coronary intervention and antiplatelet therapy in patients who have undergone endovascular graft exclusion.
Prior studies have shown a consistent relationship between coronary artery calcium (CAC) scores or the degree of coronary stenoses on coronary computed tomography angiography (CCTA) and all-cause mortality. Whether CCTA-targeted therapy, including intensive medical management, stress testing and/or invasive coronary angiography (ICA), can lead to a substantial reduction in adverse outcomes is not yet known.
Dual antiplatelet therapy (DAT, i.e. aspirin+thienopyridine) has been shown to reduce the risk of stent thrombosis (ST) and myocardial infarction (MI) after coronary stent implantation. Data regarding alternative antiplatelet therapy in patients with allergy or intolerance to aspirin are lacking.
Transendocardial gene delivery may expose patients to the risk of pericardial perfusion due to excessive needle injections. This study investigated the feasibility and safety of transendocardial gene injection using a newly developed multifunctional intracardiac echocardiography catheter.
Beta-blocker prevents sudden cardiac death in patients with hemodialysis.
Beta blockers were shown to prevent SCD in cardiomyopathy or coronary artery disease patients. Dialysis patients show elevated mortality rates, predominantly due to cardiovascular disease. SCD is now one of the leading causes of death in this population. However, the prevention of SCD remains to be elucidated.
Myocardial necrosis is a time-dependent event. Nevertheless, clinical studies on association between ischemic time and left ventricle function showed inconsistent findings. Aim of current study is to evaluate the association between ischemic time and the post-infarction left ventricular function in ST-elevation myocardial infarction treated with primary PCI.
Sirolimus- vs. paclitaxel-eluting stent to coronary intervention in dialysis patients.
Patients on maintenance hemodialysis (HD) are at high risk for restenosis after percutaneous coronary intervention (PCI) even if treated with a sirolimus-eluting stent (SES). The aim of this study was to compare the effects of SES and paclitaxel-eluting stent (PES) in preventing restenosis in HD patients with coronary artery disease.
To examine relationship between carotid intima-media thickness (IMT) and central obesity, cardiovasculary risk factors, and chronic inflammation markers in overweight and obese schoolchildren in Eastern Turkey.
Self-reported health status (EQ-5D) in adults with congenital heart disease.
Today, more patients with congenital heart disease (CHD) reach adulthood. There are conflicting findings concerning the relationship between quality of life (QoL) or health state for adults with CHD and the complexity of their CHD. The aim of the study was, firstly, to compare the reported health status and health perception of adult patients with CHD and, secondly, to investigate what variables influenced the patients' health status and health perception.
Currently, recanalization of chronic total occlusions (CTOs) in peripheral arteries remains a challenging obstacle encountered by clinical practitioners. Percutaneous CTO interventions are associated with low rates of procedural success using standard guidewires and catheters. When guidewires cannot cross the occluded segment or fail to reenter the true lumen after subintimal crossing of the occlusion, successful recanalization may be unachievable. In the last few years, the emergence of novel devices and n...
Targeting cell death in the reperfused heart: Pharmacological approaches for cardioprotection.
During acute myocardial infarction and in the reperfused heart, loss of cardiomyocytes is mostly caused by apoptosis and necrosis. As apoptosis was considered as the only form of regulated cell death for many years, initial studies investigating cardiomyocyte cell death mainly focused on direct inhibition of apoptosis. However, it has become clear that ischemic conditioning protocols - the application of alternating periods of non-lethal ischemia and reperfusion - can reduce necrotic cell death in the reper...
Animal models of organic heart valve disease.
Heart valve disease is a frequently encountered pathology, related to high morbidity and mortality rates in industrialized and developing countries. Animal models are interesting to investigate the causality, but also underlying mechanisms and potential treatments of human valvular diseases. Recently, animal models of heart valve disease have been developed, which allow to investigate the pathophysiology, and to follow the progression and the potential regression of disease with therapeutics over time. The...
