Filter by:Differentiating hypertrophic cardiomyopathy (HCM) from hypertensive heart disease (HHD) unavoidably encounters diagnostic challenges especially in patient of suspected HCM with history of hypertension. Diverse and overlapping forms of HCM can often lead to ambiguity when diagnosis is based on a single genetic or morphological index. The investigators have deduced a integrated formula based on cardiac magnetic resonance (CMR) imaging and established a differentiating flow-chart between HCM and HHD, the investigators aim to identify their method in the current multi-center trial.
This study will evaluate if the introduction of a supported exercise programme can improve physical and psychological well-being for adults with congenital heart disease.
To evaluate the clinical safety and efficacy of a new Medtronic Coronary Drug-Coated Balloon Catheter in the treatment of de novo lesions, small vessel disease or In-Stent Restenosis with coronary lesions previously treated with drug-eluting or bare metal stents in native coronary arteries.
This study aims to examine the psychological well-being and QoL of Hong Kong Chinese adolescents with CHD by - comparing the self-esteem level, depressive symptoms, and quality of life of adolescents suffering from CHD with healthy norms and cancer survivors. - identifying possible factors affecting the quality of life of adolescents suffering from CHD.
Infants born with heart problems are at risk of developing gut disease due to reduced blood flow to the intestines which can result in poor weight gain, surgery and even death. At present, doctors are often unaware of any gut problems until clinical symptoms present (poor feed tolerance, blood stained stools or bloated stomach) which is often too late to prevent gut damage. Earlier diagnosis of gut disease may now be possible; calprotectin is produced when the gut is inflamed and can be found in faeces and blood. Calprotectin levels have been shown to be a reliable marker in diagnosing gut disease in premature infants. To date, calprotectin levels have not been monitored in infants with cardiac defects, who like premature infants are at high risk of gut disease but the cause of gut disease is different to that seen in premature infants and therefore requires specific monitoring. This study will implement a high risk feeding protocol which has been adapted from current feeding practices from the United States; the aim being to promote weight gain without increasing the risk of gut inflammation. Furthermore, the study will validate whether faecal calprotectin is a useful non-invasive marker in identifying gut disease in infants with cardiac defects. Currently, infants are diagnosed with necrotising enterocolitis by an abdominal X-ray (current 'Gold Standard'); infants who have a positive diagnosis will have faecal calprotectin levels cross-checked. From this data, cut-off values will be established which will provide data to diagnose necrotising enterocolitis eliminating the need for X-rays (radiation). Secondly, faecal calprotectin levels will be measured at strategic time points (longitudinal data) linked to increased risk of gut damage (following cardiac surgery and feeding) which will then be cross-checked against infants that developed NEC to identify whether high risk infants had raised calprotectin levels earlier.
The investigators will evaluate the accuracy of non-invasive hemoglobin monitor (Sp-Hb) compared to traditional laboratory hemoglobin (Lab-Hb) in children with congenital heart disease. The investigators will also compare the accuracy of Sp-Hb in cyanotic children to acyanotic children.
Currently there is an increase in the use of bioprosthesis worldwide (> 70% according to national data of the Spanish Society of Thoracic and Cardiovascular Surgery). There is conflicting evidence regarding the long-term survival of patients aged 50-65 years with mechanical (M) or biological (B) aortic prostheses. General consensus of greater complications associated with the use of long-life anticoagulation in M and of reoperation in B. Similar survival with lower MACCE complications in bioprosthesis could reconsider their choice in patients aged 50-65 years, specially in the current TAVI era. The investigators are going to perform a multicentric retrospective observational study (Registry) about 15 year-outcomes Following Bioprosthetic vs Mechanical Isolated Aortic Valve Replacement for Aortic Stenosis in Patients Aged 50 to 65 Years in 5 Cardiovascular Surgery Centers in Andalousia (south Spain)
CAROLE seeks to evaluate the relationship between chest Radiation Therapy and coronary artery disease. The purpose of CAROLE is to check the heart health of women who received breast cancer treatments in the past and protect them from future heart disease.
The primary reason the investigators are doing this study are to understand how the right side of the heart functions in heart failure patients with left ventricular assist devices (LVADs, or "mechanical hearts"). Second, the investigators are interested in understanding how different pacemaker settings influence function of the heart at rest and activity.
Evaluating the additional value of Macrophage Migration Inhibitory factor (MIF) in cardiovascular diseases when assessed in clinical routine.
