2. Heart failure - Wikipedia

   en.wikipedia.org/wiki/Heart_failure

   In a person who is compensated, this may show cardiomegaly (visible enlargement of the heart), quantified as the cardiothoracic ratio (proportion of the heart size to the chest). In left ventricular failure, evidence may exist of vascular redistribution (upper lobe blood diversion or cephalization), Kerley lines, cuffing of the areas around the ...

3. Heart failure with preserved ejection fraction - Wikipedia

   en.wikipedia.org/wiki/Heart_failure_with...

   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.

4. Ejection fraction - Wikipedia

   en.wikipedia.org/wiki/Ejection_fraction

   It can refer to the cardiac atrium, [1] ventricle, [2] gall bladder, [3] or leg veins, [4] although if unspecified it usually refers to the left ventricle of the heart. EF is widely used as a measure of the pumping efficiency of the heart and is used to classify heart failure types. It is also used as an indicator of the severity of heart ...

5. Pathophysiology of heart failure - Wikipedia

   en.wikipedia.org/wiki/Pathophysiology_of_heart...

   Whilst left-sided heart failure will reduce cardiac output to the systemic circulation, the initial symptoms often manifest due to effects on the pulmonary circulation. In systolic dysfunction, the ejection fraction is decreased, leaving an abnormally elevated volume of blood in the left ventricle. In diastolic dysfunction, the end-diastolic ...

6. Left ventricular hypertrophy - Wikipedia

   en.wikipedia.org/wiki/Left_ventricular_hypertrophy

   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

7. Dilated cardiomyopathy - Wikipedia

   en.wikipedia.org/wiki/Dilated_cardiomyopathy

   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.

8. Ventricular hypertrophy - Wikipedia

   en.wikipedia.org/wiki/Ventricular_hypertrophy

   Ventricular hypertrophy (VH) is thickening of the walls of a ventricle (lower chamber) of the heart. [ 1 ] [ better source needed ] Although left ventricular hypertrophy (LVH) is more common, right ventricular hypertrophy (RVH), as well as concurrent hypertrophy of both ventricles can also occur.

9. Management of heart failure - Wikipedia

   en.wikipedia.org/wiki/Management_of_heart_failure

   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 ...
