A 19-year-old female asked:

is avnrt or atrial tachycardia more dangerous in an athlete?

1 doctor answer2 doctors weighed in
Dr. Milton Alvis, jr
Preventive Medicine 41 years experience
Unclear-Probably Yes: Athletic activity ↑es heart rates (per brain control to ↑ venous return, stroke volume & rate to ↑ cardiac output). It thus may compound atrial tachycardia in a partially additive way. Yet, more commonly what happens is that the brain induced rate ↑es simply over-ride the AVR induced rates. Best optimize NMR lipoprotens, HbA1c (best ≤5.0%), get a quality echocardiogram & review images carefully!

Can athletes benefit from fish oil?

2 doctor answers3 doctors weighed in
Dr. Albert Pizzo
Family Medicine 60 years experience
Fish oil/athletes: Yes. A major deficiency in the american diet are essential fatty acids e.g. Omega 3 oils from fish. Because omega 3 oils are part of the essential nutrients necessary for optimum health, anyone (including athletes) who is deficient would be healthier if they would optimize their intake of omega 3 fish oils.

Which layer of the heart enlarges in athletes?

1 doctor answer2 doctors weighed in
Dr. Danny Proffitt
Family Medicine 43 years experience
Left ventricle: It is usually the left ventricle that enlarges (hypertrophies) in athletes. This is the main pumping chamber of the heart. Other areas can enlarge depending on the condition causing it. If concerned, get it checked out. You may need an EKG and an echocardiogram (ultrasound of the heart).

What is the cause of sudden death in elite athletes?

Dr. James Chen
Sports Medicine 15 years experience
Thickened heart: The most common cause of sudden death in elite athletes in the US is hypertrophic cardiomyopathy. This is a rare condition of the actual muscle of the heart becoming so large and thick as to obstruct outgoing blood flow. Because outgoing flow is reduced the heart must work even harder to pump blood to supply oxygen to the body.
Dr. Ed Friedlander
Pathology 44 years experience
I have a special interest in this, and for the USA, Dr. Chen is correct. There are a variety of other molecular and anatomic birth defects involving the heart. Sadly, cocaine's killed too many athletes, as has neglecting common-sense safety in the heat. An athlete with known heart disease or sickle trait may still play the sport he/she loves, acknowledging the risks.

Will having polycythemia make my son a better athlete?

2 doctor answers5 doctors weighed in
Dr. Andrew Nordine
Pediatrics 20 years experience
No: Polycythemia (increased red cells in the blood) will not make him a better athlete. Within limits, it increases the oxygen deliverable by blood and may improve endurance. Elite endurance athletes sometimes train in lower oxygen (e.g. At altitude) to induce a form of polycythemia. This is not advised for children. Polycythemia should be evaluated as it can be dangerous and signal serious disease.
