Out of all the patients that receive a CRT-D ( a dual chamber pacemaker with defibrillator ) for cardiac resynchronization therapy there is approximately one-third that do not respond. We believe that by using a simple technique that includes routine echocardiography that are normally performed in these patients could help us better understand how to program their device to reach better optimization.

The purpose of this study is to evaluate the effects of BMS-986231 on systolic and diastolic parameters in patients with heart failure and low ejection fraction.
Aims: To test the hypothesis that Diastolic dysfunction severity correlates with adverse clinical outcome in patients with systolic heart failure.
The PREMEDIC is a prospective, observational study. Patients hospitalized for Systolic Heart Failure will be enrolled and health data will be collected at hospital admission and during hos...
This study will compare the ability of the heart to increase its contractile performance during stress in patients with a history of heart failure without systolic dysfunction and in contr...
This prospective observational study is designed to confirm the prognostic and economic impact of depression in ambulatory patients with systolic or diastolic heart failure, to explore the...
Quantification of systolic function in patients with atrial fibrillation (AF) is challenging. A novel approach, based on RR interval correction, to counteract the varying heart cycle lengths in AF has...
Heart failure is a common form of heart disease associated with progressive exercise intolerance and high risk of adverse clinical outcome events. The pathophysiology of chronic systolic heart failure...
The purpose of this study was to describe the temporal trends in prevalence of left ventricular systolic dysfunction (LVSD) in individuals without and with heart failure (HF) in the community over a ...
Heart failure (HF) is accompanied by major neuroendocrine changes including the activation of the natriuretic peptide (NP) pathway. Using the unique model of patients undergoing implantation of the CA...
This study investigated the impact on all-cause mortality of airflow limitation indicative of chronic obstructive pulmonary disease or restrictive spirometry pattern (RSP) in a stable systolic heart f...
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 contraction during SYSTOLE leading to defective cardiac emptying.
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.
Heart murmurs which are systolic in timing. They occur between the first and the second HEART SOUNDS, between the closure of MITRAL VALVE and TRICUSPID VALVE and the closure of semilunar aortic and pulmonary valves. Systolic murmurs include ejection murmurs and regurgitant murmurs.
A selective beta-1-adrenergic partial agonist. Because it is a partial agonist (DRUG PARTIAL AGONISM) it acts like an agonist when sympathetic activity is low and as an antagonist when sympathetic activity is high. It reduces MYOCARDIAL ISCHEMIA and improves ventricular function in patients with mild to moderate heart failure. In patients with severe heart failure it has been shown to produce benefits in systolic and diastolic function.
Cardiology is a specialty of internal medicine. Cardiac electrophysiology : Study of the electrical properties and conduction diseases of the heart. Echocardiography : The use of ultrasound to study the mechanical function/physics of the h...
