What are the symptoms of heart failure?

  • eeling like you can’t catch your breath, which worsens when you lie flat
  • Feeling tired all over
  • Swelling in your feet, ankles, and legs
Symptoms usually develop slowly. At first you may feel out of breath only when you climb stairs and notice only a little leg swelling at the end of the day. Later, you may feel out of breath or tired when you do ordinary activities. When heart failure is severe, you may be out of breath even sitting in a chair and have a lot of leg swelling all the time.

Heart failure can shorten your life, especially when it's severe. Treatment can help you live longer.

Pathophysiology of heart failure

Pathophysiology of heart failure In heart failure, the heart may not provide tissues with adequate blood for metabolic needs, and cardiac-related elevation of pulmonary or systemic venous pressures may result in organ congestion. This condition can result from abnormalities of systolic or diastolic function or, commonly, both. Although a primary abnormality can be a change in cardiomyocyte function, there are also changes in collagen turnover of the extracellular matrix. Cardiac structural defects (eg, congenital defects, valvular disorders), rhythm abnormalities (including persistently high heart rate), and high metabolic demands (eg, due to thyrotoxicosis) also can cause HF.

Boyle’s Law

Boyle’s Law Changes in intrapulmonary pressure occur as a result of changes in lung volume. This follows from Boyle’s law, which states that the pressure of a given quantity of gas is inversely proportional to its volume. An increase in lung volume during inspiration decreases intrapulmonary pressure to subatmospheric levels; air therefore goes in. A decrease in lung volume, conversely, raises the intrapul- monary pressure above that of the atmosphere, expelling air from the lungs. These changes in lung volume occur as a consequence of changes in thoracic volume,
