THE CAUSES AND CARE 1 The Causes and Care of Heart Failure A. Investigated Disease Process The investigated disease process I have chosen to focus on is heart failure. Heart failure affects nearly six million Americans with an estimated half of those dying within five years of diagnosis according to the American Heart Association, n.d. It is also estimated that most of all
THE CAUSES AND CARE 2 cardiovascular disease is preventable (American Heart Association, n.d.). Cardiovascular disease many times precedes heart failure and is primarily due to unhealthy lifestyles. It is projected that the number of people diagnosed with heart failure will increase by forty-six percent by the year twenty-thirty (American Heart Association News, n.d.). The author has selected this topic because her nursing career began as a cardiac nurse on a specialty floor at our local hospital. I want to expand my knowledge of heart failure causes and how it affects my local community. The scope of the impact of the disease is so broad I believe it is imperative I learn more about the subject to better educate the patients I care for and the community I live in. A1. Pathophysiology A general approach to understanding the sequence of factors that result in an alteration in normal functions at the systems level begin with comorbidities such as diabetes and hypertension. In addition to disease, unhealthy lifestyles contribute to a rise in those affected by heart failure. The growing aged population, obesity, and advances in medicine that prolongs life expectancies are also blamed for the increase of heart failure. People experiencing heart attacks are surviving instead of dying, and then facing a higher risk of heart failure after the infarction. Genetic disposition to heart disease also plays a part, and when combined with an unhealthy lifestyle, the chances of having heart problems are high. Smoking, excess alcohol, and eating unhealthy foods all contribute to an unhealthy lifestyle. Heredity factors, on the other hand, are ‘unmodifiable’ risks. Those with unmodifiable risks can still lower their overall dangers by altering their lifestyles and practicing proper nutrition, exercise, and smoking cessation. Hypertension is one comorbidity factor that occurs over time and can go uncontrolled and unnoticed. The pressure in the arteries gradually increase, and the inner lining of those arteries
THE CAUSES AND CARE 3 are damaged because of the high pressures. Those damaged linings provide better places for fats from foods to accumulate and get stuck in. Eventually, this causes the arteries to become less elastic in turn limiting blood flow through the body. Hypertension accounts for seventy-five percent of heart failure cases worldwide (Huether & McCance, 2018). Other factors that put people at high risk of heart failure are obesity, renal failure, age, smoking, cardiomyopathies, valvular heart disease, myocarditis, congenital heart disease and excessive alcohol use (Huether & McCance, 2018).
