Valve (Definition)

A valve is a structure that regulates the direction of flow. The heart is a special kind of pump. It moves blood by squeezing and relaxing. There are 4 chambers and each chamber has a valve. This keeps blood from moving backwards when the heart squeezes. When a chamber squeezes it lets the blood move forward but when the chamber is relaxed it prevents the blood from ...Read more

How can we distinguish 'stunned' from 'hibernating' myocardium?

How can we distinguish 'stunned' from 'hibernating' myocardium?

Time: Stunned myocardium implies a short-term injury to the heart resulting in decreased function of the heart which recovers in 10-14 days. Hibernating myocardium implies a chronically decreased blood supply to the heart which results in poor heart function. Unlike stunned myocardium, the heart function in hibernating myocardium will not improve until the blood supply is repaired. ...Read more

Dad has weak myocardium and he had stents before he takes enalapril will his condition improve ?

Dad has weak myocardium and he had stents before he takes enalapril will his condition improve ?

Probably: Enalapril is one of the meds we use to strengthen myocardium. Revascularization of blockages with stents and bypasses is another important part if it! ...Read more

Nuclear stress test is fine but "perfusion is mildly nonuniform but appears preserved throughout myocardium."what does this mean? should i be worried?

Nuclear stress test is fine but "perfusion is mildly nonuniform but appears preserved throughout myocardium."what does this mean? should i be worried?

Don't worry: There is often a difference between true perfusion (circulation of blood) and the APPEARANCE of perfusion on a nuclear stress test. Variations in the thickness of the chest wall, caused by breast tissue or other factors, could explain the findings on your test. Most important, however is your doctor's overall assessment based on all known information. ...Read more

What is the medical definition of hibernating myocardium ?

What is the medical definition of hibernating myocardium ?

Alive but...: Hibernating myocardium is heart muscle that is viable and alive but unable to contract normally. It is generally related to inadequate blood supply to that area of the heart. ...Read more
