2. Heart failure - Wikipedia

   en.wikipedia.org/wiki/Heart_failure

   The left side of the heart takes oxygen-rich blood from the lungs and pumps it to the rest of the circulatory system in the body (except for the pulmonary circulation). Failure of the left side of the heart causes blood to back up into the lungs, causing breathing difficulties and fatigue due to an insufficient supply of oxygenated blood.

3. 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 ...

4. Impella - Wikipedia

   en.wikipedia.org/wiki/Impella

   Transseptal intervention in addressing physiologic mismatch in perfusion between left- and right-sided heart failure is in experimental status. [ citation needed ] However, recent studies point to significantly greater in-hospital risks of major bleeding, death, and other adverse events for patients supported by Impella devices, compared with ...

5. Ventricular outflow tract obstruction - Wikipedia

   en.wikipedia.org/wiki/Ventricular_outflow_tract...

   This can lead to cardiac hypertrophy, dilatation of the heart, and ultimately heart failure in some cases. [1] The right side of the heart is much smaller and weaker than the left side of the heart. It pumps de-oxygenated blood into the lungs. The left side of the heart is more muscular than the right side of the heart.

6. Cardiac resynchronization therapy - Wikipedia

   en.wikipedia.org/wiki/Cardiac_resynchronization...

   Cardiac resynchronisation therapy (CRT or CRT-P) is the insertion of electrodes in the left and right ventricles of the heart, as well as on occasion the right atrium, to treat heart failure by coordinating the function of the left and right ventricles via a pacemaker, a small device inserted into the anterior chest wall.

7. Myocardial infarction complications - Wikipedia

   en.wikipedia.org/wiki/Myocardial_infarction...

   A myocardial infarction may compromise the function of the heart as a pump for the circulation, a state called heart failure. There are different types of heart failure; left- or right-sided (or bilateral) heart failure may occur depending on the affected part of the heart, and it is a low-output type of failure.
