Left-Sided Congestive Heart Failure due: Describe the common causes of left-sided congestive heart failure. Discuss the disorders that typically result in left-sided failure. What are the classic signs and symptoms of left-sided failure?
Left-sided congestive heart failure is a fatal condition whereby the heart fails to pump sufficient blood to the body due to a malfunctioning left ventricle. It can manifest in two ways: systolic or diastolic failure. Systolic failure occurs when the left ventricle fails to contract strongly enough to push blood through the body, while diastolic failure occurs when the left ventricle cannot relax enough to allow in more blood due to stiffening of the muscles. Common causes of left-sided heart failure include excessive consumption of alcohol, history of heart attack, bacterial and viral infections to the heart muscles, hypertension and leaking and narrowing of the cardiac valves. This can be as a result of consumption of poor diets or unhealthy lifestyle (Timby & Smith, 2005).
Disorders leading to left-sided congestive heart failure can be seen in both children and adults. In children, it can be caused by birth defects involving the heart and heart muscles such as abnormal heart valves or blood vessel connection. In adults, such disorders include hypothyroidism and other inherited heart conditions that can lead to cardiomyopathy. High blood pressure, diabetes mellitus, obesity and coronary artery diseases are other risk factors for left-sided congestive heart failure (Hobbs & Boyle, 2014).
According to Robinson, N. E., & Sprayberry (2009), the most common symptom for left-sided heart failure is fatigue, weakness or faintness as a result of insufficient supply of oxygen to the body. Other symptoms include shortness of breath due to excess fluid accumulation in the lungs, decreased urine production and abrupt weight gain due to excessive fluid retention and cough that contains frothy or bloody mucus. Right ventricular systolic dysfunction could occur as a result of left-sided congestive heart failure (204).

Reliever inhalers are prescribed to reduce the asthma signs, and they do not minimize the swelling and inflammation in the airway (Wojciechowski, 2011). People suffering from mild asthma are treated with inhaled corticosteroid combined with a long-acting beta-two agonist (Wojciechowski, 2011). In such a case Flovent 110 and Severent is prescribed.

...Pathophysiology Diagnosis The physician should give Mr. Ally an eye exam. The examination should encompass dilating the eyes todetermine whether the retina is detached. Fundamentally, the physician should utilize the ophthalmoscopy and ultrasonography in the diagnosis. The ophthalmoscopy is essential for the examination of Mr. Ally’s eyes because it offers a highly defined three-dimensional view that enables the physician to see the presence of detachment or retinal holes. Similarly, the doctor should use the ultrasonography to create images of the retina on a video monitor for the diagnosis of the retinal detachment. The two tests will be crucial in the diagnosis of the retinal detachment in Mr. Ally’s eyes. Floaters and...
