Which of the following recurring condition most commonly occurs in clients with cardiomyopathy?

Myocardial oxygen consumption increases as which of the following parameters increase?
A Preload, afterload, and cerebral blood flow
B Preload, afterload, and renal blood flow
c Preload, afterload, contractility, and heart rate
D Preload, afterload, cerebral blood flow, and heart rate.

A, C
HF is a result of structural and functional abnormalities of the heart tissue muscle. The heart muscle becomes weak and does not adequately pump the blood out of the chambers. As a result, blood pools in the left ventricle and backs up into the left atrium, and eventually into the lungs. Therefore, greater amounts of blood remain in the ventricle after contraction thereby decreasing cardiac output. In addition, this pooling leads to thrombus formation and ineffective tissue perfusion because of the decrease in blood flow to the other organs and tissues of the body. Typically, these clients have an ejection fraction of less than 50% and poorly tolerate activity. Activity intolerance is related to a decrease, not increase, in cardiac output. Gas exchange is impaired. However, the decrease in cardiac output triggers compensatory mechanisms, such as an increase in sympathetic nervous system activity.

What are complications of cardiomyopathy?

This can cause blood to flow backward in the valve. Cardiac arrest and sudden death. Cardiomyopathy can trigger irregular heart rhythms that cause fainting or, in some cases, sudden death if the heart stops beating effectively.

What are 4 signs of cardiomyopathy?

Signs and symptoms of cardiomyopathy include:.
Shortness of breath or trouble breathing, especially with physical exertion..
Fatigue..
Swelling in the ankles, feet, legs, abdomen and veins in the neck..
Dizziness..
Lightheadedness..
Fainting during physical activity..
Arrhythmias (abnormal heartbeats).

What happens when you have cardiomyopathy?

Cardiomyopathy refers to conditions that affect your heart muscle. If you have cardiomyopathy, your heart can't efficiently pump blood to the rest of your body. As a result, you may experience fatigue, shortness of breath or heart palpitations. Cardiomyopathy gets worse over time.

Which condition is most commonly responsible for myocardial infarction?

Most myocardial infarctions are due to underlying coronary artery disease, the leading cause of death in the United States. With coronary artery occlusion, the myocardium is deprived of oxygen. Prolonged deprivation of oxygen supply to the myocardium can lead to myocardial cell death and necrosis.
