Heart failure is a chronic disease that usually progresses gradually. [20] The rate of progression and the degree of symptoms of the disease varies between different patients. Cardiac contractility modulation therapy aims to treat heart failure through a medium- to long-term treatment, over the course of weeks and months. [citation needed]
Heart failure is a leading cause of hospital readmissions in the U.S. People aged 65 and older were readmitted at a rate of 24.5 per 100 admissions in 2011. In the same year, heart failure patients under Medicaid were readmitted at a rate of 30.4 per 100 admissions, and uninsured people were readmitted at a rate of 16.8 per 100 admissions.
Cardiac monitoring generally refers to continuous or intermittent monitoring of heart activity to assess a patient's condition relative to their cardiac rhythm.Cardiac monitoring is usually carried out using electrocardiography, which is a noninvasive process that records the heart's electrical activity and displays it in an electrocardiogram. [1]
Before the development of the Bruce protocol there was no safe, standardized protocol that could be used to monitor cardiac function in exercising patients. Master's two-step test [7] was often used, but it was too strenuous for many patients, and inadequate for the assessment of respiratory and circulatory function during varying amounts of ...
Impedance cardiography (ICG) is a non-invasive technology measuring total electrical conductivity of the thorax and its changes in time to process continuously a number of cardiodynamic parameters, such as stroke volume (SV), heart rate (HR), cardiac output (CO), ventricular ejection time (VET), pre-ejection period and used to detect the impedance changes caused by a high-frequency, low ...
Acute decompensated heart failure (ADHF) is a sudden worsening of the signs and symptoms of heart failure, which typically includes difficulty breathing , leg or feet swelling, and fatigue. [1] ADHF is a common and potentially serious cause of acute respiratory distress. The condition is caused by severe congestion of multiple organs by fluid ...
By showing the relative amounts of radioisotope within the heart muscle, the nuclear stress tests more accurately identify regional areas of reduced blood flow. [12] Stress and potential cardiac damage from exercise during the test is a problem in patients with ECG abnormalities at rest or in patients with severe motor disability.
Congestive heart failure patients that were implanted with an ICD had an all-cause death risk 23% lower than placebo and an absolute decrease in mortality of 7.2 percentage points after five years in the overall population. 1 Reporting in 1999, the Antiarrhythmics Versus Implantable Defibrillators (AVID) trial consisted of 1,016 patients, and ...
