What is left sided congestive heart failure?
Heart failure is a condition where the heart grows a lot larger due to it requiring a greater pumping force. This can be either due to increased blood volume or more likely, due to increased systemic resistance. A common cause of this is systemic atherosclerosis or aortic stenosis. The problem is, the large heart cannot be sustained for long and eventually the wall just thins out and becomes weak. So your heart can’t pump out as much blood as before, giving you symptoms such as breathlessness, palpitations, fluid swelling, raised JVP etc.
