Cardiovascular System Case Study

Better Essays
Cardiovascular system is an organ system that helps in the circulation of blood and transportation of nutrients, oxygen, carbon dioxide and hormones to and from the cells in the body to provide nourishment and prevent diseases, stabilize temperature and pH and maintain homeostasis. It consists of the heart and the blood vessels. This assignment contains different aspects of the same. The first question is about the various differences between the cardiovascular system of a normal adult and older adult followed by the brief description of the main medical problems related to cardiovascular diseases and the effects of various factors including genetics, gender and stress etc, as the determinants of these problems. Finally, it consists of various …show more content…
-High resistivity to infections due to -Resistivity towards infections and strong immunity (neutrophils). diseases decreases due to weak immunity (neutrophils).
BLOOD VESSELS: -Normal walls of capillary leading to -The capillary walls thicken slightly regular exchange of materials through leading to slower rate of exchange of blood. of nutrients and waste materials.
The five common medical problems related to cardiovascular diseases are:-

Coronary Artery Disease(CAD):
CAD is called atherosclerosis, or hardening, of the arteries that provide vital oxygen and nutrients to the heart. It occurs generally due to the settling down of excess cholesterol in the arteries, narrowing and blocking the space through which the blood flows. It leads to pain in the chest, shortness of breath and also becomes the cause of heart

Role of gender: Differences in sex does not affect the condition of failure of heart.
Role of psychological stress: Stress may affect behaviours and factors that increase heart disease risk including high blood pressure and cholesterol levels, leading to strokes in the heart.

Cardiomyopathy:
In cardiomyopathy, the heart muscle becomes enlarged, thick, or rigid. In rare cases, the muscle tissue in the heart is replaced with scar tissue. As cardiomyopathy worsens, the heart becomes weaker. It 's less able to pump blood through the body and maintain a normal electrical rhythm. This can lead to heart failure or irregular heartbeats called arrhythmias. In turn, heart failure can cause fluid to build up in the lungs, ankles, feet, legs, or abdomen.
Role of genetics: The risk of cardiomyopathies increases when there are pre-existing genetic condition known as monogenic conditions for it.
Role of gender: Men have an increased incident and severity of most cardiovascular diseases including cardiomyopathy than women.
Role of psychological stress: Intense emotional or physical stress leads to rapid and severe reversible cardiac dysfunction causing cardiomyopathy.

    What is Heart Failure? According to MayoClinic.Org,” Heart failure, sometimes referred to as congestive heart failure, occurs when your heart muscle doesn't pump blood as well as it should. Certain conditions, such as narrowed arteries in your heart (coronary artery disease) or high blood pressure, gradually leave your heart too weak or stiff to fill and pump efficiently.” Web. . January 12, 2016 There are contributing factors that can lead to heart failure such as coronary artery disease, diabetes, obesity, and high blood pressure.…

    Heart failure is when the heart stops functioning properly, this is a cause of death. Congestive heart failure would be when the heart does not pump blood as well as it should. According to Mayo Clinic it states that, angiotensin converting enzyme inhibitors help someones hearts get in good or even better conditions. Essentially, ACE helps people with systolic heart failure. Systolic heart failure is when the ejection fraction is decreased, this leaves an unusual volume of blood in the left ventricle.…

    High cholesterol is one of the causes of coronary artery disease which is a type of cardiovascular disease (Lewis, et al., 2014, p. 731). Chronic endothelial injury from hypertension, etc play a central role in the development of CAD. When there is already damage done cholesterol accumulates in the smooth muscle of the vessel called a fatty streak (Lewis, et al., 2014, p. 731). The next two stages are fibrous plaque and complicated lesion (Lewis, et al., 2014, p. 731). The vessel narrows due to this process which reduces the blood flow to tissues (Lewis, et al., 2014, p. 731).…

    Patients on PPV can have a weakened cardiac output based on their chest wall and lung compliance, their airway resistance (Raw) and the airway pressure (Paw). When the airway pressure in the patient increases it also increases intrapleural pressure and it compresses the blood vessels inside the heart causing the central venous pressure (CVP) to rise. When this occurs, the pressure gradient decreases between the systemic veins and the right side of the heart, which decreases the venous return to the right side of the heart. It also decreases preload or right ventricular filling. In effect, the right ventricular stroke volume…

    In the case of coronary heart disease, it directly affects the heart where the coronary arteries experience atherosclerosis which reduces the blood flow to the heart. In a result, the heart’s pumping ability is greatly reduced. Concerning other medical conditions like obesity, diabetes, and thyroid disease, if not cared or controlled for properly, will contribute to congestive heart…

    Insulin resistance can cause extremely detrimental effects on cardiac contractility by decreasing the body’s ability to supply ATP. Once again, this can lead to cardiac remodeling and heart failure. This heart failure will lead to the activation of RAAS which will perpetuate the cyclical problem. Between the mechanical and the neurohumoral issues seen with systolic ventricular dysfunction, one can see how each system and mechanism feeds the other. Hypertension from an unhealthy life style can cause a small amount of damage to the left ventricle.…

    Next, the causes of heart failure could be a virus like Myocarditis that influences the heart, fatty material that blocks the blood vessels, or a disease like High Blood Pressure that makes the heart work hard. After that, the symptoms divided into common like Breathlessness and fatigue, and uncommon like loss appetite and weight gain or loss. Next, the risk factors divided into controllable such as diabetes and overweight and uncontrollable like age and race. After that, the treatment could be a drug like Beta blockers, or surgical like heart transplant. finally, we have to be aware of heart failure because it could be fatal if not treated…

    This type of situation is called coronary artery disease, or atherosclerosis means the hardening of the arteries in which fatty deposits build up inside the coronary arteries. Heart attack, or againa occurs when a blood clot develops from plaque in one of the arteries. As the clot gets bigger, it becomes harder to supply blood and oxygen to the heart. The most common symptoms are chest pain, discomfort, burning, aching across the chest,…

    This hence determines the likelihood of a decompensated heart failure. Furthermore, it means that the wall separating the left ventricle is not working well like the muscles around it due to ventricular failure, causing fluid buildup which leaks into interstitial and pleural space and eventually into alveoli (Croft & Gordon…
