Sleep apnea is an under-recognized risk factor for heart failure. Uncontrolled sleep apnea may increase the risk of heart failure by up to 140%. [4] Weight reduction – through physical activity and dietary modification, as obesity is a risk factor for heart failure and left ventricular hypertrophy. Effective weight management has been shown ...
Cardiac contractility modulation (CCM) is a treatment for people with moderate to severe left ventricular systolic heart failure (NYHA classes II–IV), which enhances both the strength of ventricular contraction and the heart's pumping capacity.
Heart failure with preserved ejection fraction (HFpEF) is a form of heart failure in which the ejection fraction – the percentage of the volume of blood ejected from the left ventricle with each heartbeat divided by the volume of blood when the left ventricle is maximally filled – is normal, defined as greater than 50%; [1] this may be measured by echocardiography or cardiac catheterization.
In simplest terms, heart failure, or congestive heart failure, occurs when the heart can’t pump enough blood to meet the body’s needs. There are four stages of heart failure. People in this ...
Based on the approval of cardiac contractility modulation devices, the therapy is a treatment option for patients that are at least 18 years old who suffer from heart failure symptoms due to left ventricular systolic dysfunction (LVSD) despite adequate medical treatment. Further clinical research are under way to identify which patient group ...
Left ventricular hypertrophy; A heart with left ventricular hypertrophy in short-axis view: Specialty: Cardiology: Complications: Hypertrophic cardiomyopathy, Heart failure [1] Diagnostic method: Echocardiography, cardiovascular MRI [1] Differential diagnosis: Athletic heart syndrome
The average age of the patients was 65 years. Patients were eligible for enrollment if they had recently been diagnosed with severe heart failure (NYHA class III or IV) and a left ventricular ejection fraction (LVEF) of 35% or less, who were already receiving standard therapy (ACE inhibitors, loop diuretics, and, if tolerated, digoxin).
Illustration of a Normal Heart vs. Heart with Dilated Cardiomyopathy. The progression of heart failure is associated with left ventricular remodeling, which manifests as gradual increases in left ventricular end-diastolic and end-systolic volumes, wall thinning, and a change in chamber geometry to a more spherical, less elongated shape.
