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.

   It is almost always indicative of left ventricular systolic impairment, and carries a poor prognosis. The condition is relatively rare, and patients with the greatest risk for developing pulsus alternans include those with heart failure, cardiomyopathy, coronary artery disease, or other cardiac risk factors.

4. Pathophysiology of heart failure - Wikipedia

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

   The symptoms of heart failure are largely determined by which side of the heart fails. The left side pumps blood into the systemic circulation, whilst the right side pumps blood into the pulmonary circulation. Whilst left-sided heart failure will reduce cardiac output to the systemic circulation, the initial symptoms often manifest due to ...

   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. If one of the heart valves is affected, this may cause dysfunction, such as mitral regurgitation in the case of left-sided coronary occlusion that disrupts ...

   Alright, even though systolic failure is most common in left-sided heart failure, diastolic heart failure or filling dysfunction can also happen. In hypertension, remember how the left ventricular hypertrophied? Well that hypertrophy is concentric, which means that the new sarcomeres are generated in parallel with existing ones.
