Kinda: Coronary refers to the heart. Cerebrovascular refers to the brain. They aren't related other than diet can effect the buildup of plaques in the vessels that can lead to heart disease and strokes. So the answer is yes, diet can effect vascular disease, including the heart and brain.

What are factors that influence the cardiac output?

Dr. Mark Milunski
Cardiology 37 years experience
Cardiac output: In strict physiologic terms, cardiac output is determined by something called stroke volume and heart rate. Heart rate is self-explanatory. Stroke volume is the amount of blood that the heart pumps out with each beat. This in turn is dependent on blood pressure, total blood volume, and how strong the heart contracts.

Varies: Assuming a true high cardiac output syndrome, patients may feel flushed with a fast heart rate. Most are transient situations, but some illnesses and conditions may cause a sustained high output state, e.g., hyperthyroidism, anemia, arterio-venous malformations (congenital or acquired low resistance connections between arteries and veins), or disease like paget's. Requires confirmation by doctor.

Cardiac Eval: Look, of course I do not know you, but unless you are 9 ft tall, 343 is probably way overweight. The best way to find your answer would be to see a cardiologist and have a good cardiac evaluation, probably including a stress test and echocardiogram. They could then give you a rational program of exercise to help improve your health and/or make other suggestions.
A 31-year-old member asked:

I'm curious what could happen when cardiac output is low and what if it's high?

1 doctor answer2 doctors weighed in
Dr. Carlos Orrego
Cardiology 28 years experience
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
