Cardiomyopathy: When the Heart Muscle is Sick

Several months ago, I devoted a couple blogs to the subject of CHF (congestive heart failure).  At the time, I discussed the differences between heart failure from systolic dysfunction (problems with the heart contracting/pumping) and that caused by diastolic dysfunction (problems during the relaxation phase of the cardiac cycle).  These are clinical syndromes and are brought on by a variety…

Why Are My Ankles Swollen?

Hardly a day goes by that I am not asked that question by a patient.  The causes are numerous, but most people’s biggest fear is that they have CHF (congestive heart failure).  Indeed, peripheral edema (edema fluid causing swelling of the extremities, usually the legs) is certainly seen with CHF, and probably is its most visible manifestation.  There, it is…

PFOs: The Most Common Hole in the Heart

What does it mean to have a “hole” in your heart? Is blood leaking out? How can you have this without knowing about it? A hole in the heart means that there is a connection between two chambers that shouldn’t be there. A patent foramen ovale (PFO) is a connection between the right and left atria. Blood normally passes from…

Aortic Aneurysms: The Danger of Dilation

We’ve spent the last several weeks discussing valvular heart disease.  Today I’ll turn our attention to a problem outside the heart—aortic aneurysms.  An aneurysm is a focal enlargement or bulging of a blood vessel.  It comes from the Greek word meaning “dilation.”  In fact, radiology reports will often use the term “dilated” to refer to a vessel that is larger…
