The purpose of this study is to evaluate long-term performance of the 4196 LV Lead. This evaluation is based on the number of lead-related complications occurring during the study compared...
Heart failure is a progressive disease that decreases the pumping action of the heart. This may cause a backup of fluid in the heart and may result in heart beat changes. When there are ch...
The purpose of the study is to assess lead implant success and complication rate using the Medtronic Attain Family of left-heart leads and delivery catheters.
This study is designed to show that a new lead, which paces the left bottom chamber (left ventricle) of the heart, is safe. Using a lead on the left side of the heart has been shown to pot...
The purpose of the Optimize RV study is to determine the long-term effect of selective site pacing. Selective site pacing refers to which area of the right ventricle the lead is placed. T...
Heart failure or congestive heart failure remains a major public health concern on the global scale. End-stage heart failure is a severe disease where the heart is unable to pump enough oxygen and nut...
Long-term data on outcomes of participants hospitalized with heart failure (HF) from low and middle-income countries are limited.
The primary aim of the TRIAGE-HF trial was to correlate cardiac implantable electronic device-generated heart failure risk status (HFRS) with signs, symptoms, and patient behaviours classically associ...
To summarize current clinical data investigating the link between diabetes and heart failure pathophysiology, the association of glucose control with heart failure, and the impact of current antihyper...
This study evaluated whether alpha-blocker (AB) use following an admission for heart failure (HF) was associated with an increased risk of HF readmission or death.
A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.
Enlargement of the HEART, usually indicated by a cardiothoracic ratio above 0.50. Heart enlargement may involve the right, the left, or both HEART VENTRICLES or HEART ATRIA. Cardiomegaly is a nonspecific symptom seen in patients with chronic systolic heart failure (HEART FAILURE) or several forms of CARDIOMYOPATHIES.
Heart failure caused by abnormal myocardial relaxation during DIASTOLE leading to defective cardiac filling.
Heart failure caused by abnormal myocardial contraction during SYSTOLE leading to defective cardiac emptying.
Congenital arteriovenous malformation involving the VEIN OF GALEN, a large deep vein at the base of the brain. The rush of arterial blood directly into the vein of Galen, without passing through the CAPILLARIES, can overwhelm the heart and lead to CONGESTIVE HEART FAILURE.
