Cardiovascular and Cardiopulmonary pathophysiologic processes that result in the patient presenting symptoms of weight gain, shortness of breath, peripheral edema and abdominal swelling is the relationship between the heart and lungs. Left Heart Failure is characterized heart failure that has a poor ejection fraction. The normal ejection fraction for a heart is 60 to 65 %. When the heart presents with poor ejection less than 40%, we have what we call heart failure (McCance & Huether, 2019). Heart failure is defined as the pathophysiologic condition where the heart is unable to generate enough cardiac output to help push oxygenated blood that come from the lungs and then is push out the oxygenated blood to the vital organs in the body. The shortness of breath comes from pulmonary congestion, which means fluids is backing up into the lungs. Due to the poor cardiac output it leads to poor venous return and fluid is now pulling in the bilateral extremities causing peripheral edema. There is a hormone in the body called Arginine Vasopressin also known as an antidiuretic hormone causes peripheral vasoconstriction and renal fluid retention, thus leading to this patient weight gain. Aldosterone is also a major component that causes salt and water retention by the kidneys……..Continue
