Filter by:The changes of left ventricular function in patients with sleep apnea were studied by three-dimensional speckle-tracking echocardiography to evaluate the changes of left ventricular function after CPAP treatment
To demonstrate that home-based exercise rehabilitation (HER) compared to usual care (UC) results in a significant reduction in healthcare utilization in HeartMate 3 (HM3) left ventricular assist device (LVAD) patients.(defined as rehospitalization, VAD Clinic visits, and ER visits during the 1st year after index discharge following LVAD implantation).
The purpose of this study is to evaluate how Eko AI performs in the real world, front-line setting where the availability of sophisticated, expensive diagnostic tools is limited, and where there is a premium on detecting VHD early in its course.
Right ventricular (RV) failure after cardiac surgery is associated with morbidity and mortality, but is hard to diagnose with conventional echocardiographic means. RV dysfunction may be associated with hepatic congestion, which may have an effect on portal veinous flow, but this has not been extensively. The investigators aimed determine whether an increased pulsatility in the portal venous flow was associated with RV dysfunction, after cardiac surgery at risk of RV dysfunction: mitral and tricuspid valve procedures.
To investigate the predictive value of inflammatory indexes and CHA2DS2-VASc score for anterior myocardial infarction (ANT-MI) with left ventricular thrombus(LVT) (LVT).
RV dysfunction has been associated with increased mortality in the ICU and cardiac surgical patients. Thus, early identification of RV dysfunction at less severe stages will allow for earlier intervention and potentially better patient outcomes. However, so far, no studies have reported prospectively the prevalence of abnormal RV pressure waveform during cardiac surgery and in the ICU. Our primary hypothesis is that the prevalence of abnormal RV pressure waveform occurs in more than 50% of cardiac surgical patients throughout their hospitalization. Those patients with abnormal RV pressure waveform will be more prone to post-operative complications related to RV dysfunction and failure in the OR and ICU.
Acute kidney injury (AKI) is classically described as an abrupt or rapidly reversible reduction in the excretion of nitrogenous waste products, including urea, nitrogen and creatinine. Acute kidney injury definition emphasizes on the filtration function of the kidney, a measure that is unique and easily and routinely measured . Acute kidney injury is associated with significantly increased resource utilization and health care costs. Major adverse cardiac events (MACE) after non cardiac surgery are a leading cause of morbidity and mortality. The reported incidence of postoperative myocardial infarction (POMI) among patients undergoing non cardiac surgery is between 3% and 6%.
This is an observational, prospective, multicenter study (12 hospitals belonging to the Italian Cardiology Network) in patients with STEMI ST elevation myocardial infarction (STEMI) treated successfully with primary percutaneous coronary intervention (PCI), that will be followed for 12 month after the acute event, in order to ascertain the predictive value of myocardial viability measured with cardiac magnetic resonance (1.5 T; based on the transmural distribution of late enhancement in the infarcted segments) for the identification of left ventricular (LV) remodelling (REM) 6 months after STEMI.
Patients undergoing coronary artery bypass grafting up tp 30% will develop postoperative right ventricle dysfunction. Its imperative for the physician to fully understand the severity of this complication in order to perform an early diagnosis and carry out the appropriate treatment. Aim: Investigate the correlation between echocardiographic measurements and hemodynamic changes at different time points in patients undergoing coronary artery bypass graft surgery Hypothesis: 1. Weak correlation between echocardiographic measurements and hemodynamic changes during coronary artery bypass graft surgery 2. Echocardiographic measurements would change across different time points during surgery independent of hemodynamic values.
COLUMBIA CARDS is a pilot study to understand how COVID-19 affects the heart. It is known that COVID-19 can affect the heart in different ways. COLUMBIA CARDS is studying why some COVID-19 survivors develop clinical conditions such as heart inflammation, fluid buildup, blood clots, and other cardiac problems during or after their COVID-19 illness, and why other ones do not. In this study, we will use cardiovascular magnetic resonance (CMR) and transthoracic echocardiography (TTE) to better understand the impact of COVID-19 on the heart.
