How Could Hyperthyroidism Affect Cardiac Output
Hyperthyroidism: Hyperthyroidism is a excess metabolic state. If other systems are normal it will usually cause increased heart rate and cardiac output. In the face of a weak heart, it could be associated with decrease in cardiac output. Chronic hyperthyroidism can be associated with a cardiomyopathy causing decreased heart function. ...Read moreSee 1 more doctor answer
Hypothyroidism is a medical condition that lowers the level of thyroid hormone to a point where the patient has a marked decrease in overall health. Often the patient does not notice the loss of thyroid hormone for several weeks or more. Once diagnosed with low thyroid hormone levels, the patient will be prescribed with thyroid hormone to a point where the thyroid levels are normal and ...Read more
Low blood pressure: Cardiac output is related to the heart rate, and volume of blood the heart can pump with each heart beat. A low cardiac output occurs when the pump function of the heart is compromised by an event such as a heart attack or when the blood volume is reduced by and event such as dehydration, or bleeding. ...Read moreSee 1 more doctor answer
Low cardiac output: Cardiac output depends on heart rate and stoke volume. Therefore, the cardiac output increases when heart rate goes up in normal heart. However, when the heart is failing the stroke volume is lower as well as the cardiac out which is called heart failure . Sometimes, heart failure could occur when cardiac output is high due to other medical problems such as a severe anemia , hyperthyroidism, etc ...Read more
Two ways: It can cause the heart muscle to get thick and stiff so that it does not relax and fill up with blood properly. It could also cause the heart muscle to become weak so that it does not squeeze or contract as forcefully. These are called diastolic dysfunction (too thick) or systolic dysfunction (weak and flabby). ...Read moreSee 1 more doctor answer
Cardiac output: is stroke volume times heart rate. if stroke volume goes down more than heart rate goes up, cardiac output won't increase. stroke volume depends on preload (filling of the heart), afterload (resistance to flow), and contractility (how much the heart pumps for how much it is filled. For instance, if the heart rate goes up but the the heart doesn't have time to fill, output won't increase. ...Read more
Cardiac output: Basically an increase in demand for oxygen by the body. This may be physiological (exercise) or pathological (sepsis - infection - fever) or increased metabolism (hyper active thyroid gland - hyperthyroidism) or abnormal conducts (shunting of blood). ...Read moreSee 1 more doctor answer
Venoconstriction?: Cardiac output is inversely proportional to total peripheral resistance (which is related to mean arterial pressure.) venoconstriction refers to the venous system and can't be measured. If venous return increases, preload increases, and by starling's law of the heart, cardiac output increases. However, severe venoconstriction could eventually diminish venous return and reduce co.
