Where do coronary arteries empty their blood?

Where do coronary arteries empty their blood?

Heart Muscle: The coronary arteries arise from the aorta and course over the surface of the heart. They supply blood to the heart muscle with nutrients and terminate in small connections called capillaries with heart veins. The health of these vessels is very important. If they become "clogged" with cholesterol plaque then the blood suppy to the heart is reduced leading to chest pain and heart attacks. ...Read more

Arteries: higher pressure, thicker walls, stretch (pulse) with each heart contraction & deliver blood to the arterioles which control the flow to individual capillaries. Veins are blood vessels which carry blood from capillaries back to the heart (body to right heart; ...Read more

What happens if someone with low blood flow due to coronary arteries receives Epinephrine due to anaphylaxis?

Is there a link to coronary artery atheroma and coughing up blood?

Is there a link to coronary artery atheroma and coughing up blood?

Not likely: Coughing up blood is usually a problem of the lung tissue or gastrointestinal track. Atheroma of the blood vessels is a complication of dietary intake and genetic makeup. While poor heart function as a result of atheroma may cause the lungs to function poorly, bloody coughs are not common. You should see your doctor for this condition as there may be something more serious going on. ...Read more

Why has my doctor not checked for coronary artery anomolies excercise chest pain.  Had echo, ecg, stress ecg, 24h ecg, bloods. 21 male.

Studies are negative: At 21 y/o with the above negative studies, i can say with certainty that you do not have coronary artery disease. I will look for chest wall pain/costochondritis, asthma induce exercise, acid reflux that can mimic pressure chest pain like from the heart, anxiety disorders. Trust your doctor, stay in shape, do not smoke or drink, eat healthy. ...Read more

Diagnosed with costochondritis.Blood, ekg,xray were normal.Could I have been misdiagnosed and have Coronary artery disease? Am 20 y/o healthy

Really, really not: You're making costochondritis sound like a big deal. Perhaps it wasn't explained to you that it isn't. Few people don't get shooting pains in their chests at some time. To doctors costochondritis is like the common cold: Can't be avoided, predicted, or prevented & it's benign. Costochondritis is a fancy word for "nothing's wrong with you." My advice: Find something else ro worry about. ...Read more

Asthma & chest pain: Asthma rarely, if ever, causes chest pains; although some triggers for asthma such as viral infections can cause 'pleurisy' (chest pains that occur with deep breathing). Other common causes for chest pains include gastric reflux (esophageal spasms) which can also triggger asthma. Chest pains that occur with a changing pattern of frequency or intensity, and with exercise should be investigated. ...Read more
